2. EP Double Shaft Planetary Gearbox with Foot Dimensions
Engineered for industrial environments that demand consistent, high-torque power transmission across dual output points, the double shaft planetary gearbox in our EP-Double shaft planetary gearboxes series combines a rugged foot-mounted housing with the mechanical advantages of a planetary gear set. Whether your operation runs conveyor lines, crushing equipment, or mixers in the field, this unit is built to keep working where standard gearboxes fall short.
The foot-mounted design simplifies installation on flat surfaces, machinery bases, and structural frames — no complicated brackets or custom adapters required. Both output shafts deliver synchronized torque simultaneously, making this a go-to solution for twin-drive configurations across mining, cement processing, and general industry in Colombia and across Latin America.
3. Five Key Product Advantages
1. Dual Output Shaft Configuration
Unlike conventional single-output planetary reducers, the double output shaft gearbox transmits torque simultaneously to two driven axes. This eliminates the need for external shaft splitters or secondary drive systems, reducing both complexity and potential failure points in demanding production environments.
2. Foot-Mounted Structural Stability
The integrated foot bracket provides a rigid, bolted connection to the machine base. This mounting approach distributes mechanical load across a wider footprint, reduces vibration transmission to the frame, and enables quick field alignment — especially valued in mobile or temporary installations common across Colombian industrial sites.
3. High Torque Density in a Compact Body
The planetary gear arrangement — sun gear driving multiple planet gears within a fixed ring gear — distributes torque across several simultaneous mesh points. The result is exceptional torque output relative to physical size. As a high torque double shaft planetary gearbox, this series handles heavy-duty cycles without increasing the machine footprint.
4. Hardened Gear Surface for Extended Service Life
All gears are manufactured from 20CrMnTi alloy steel, carburized to achieve surface hardness of 58–62 HRC while maintaining a tough core at 33–48 HRC. Post-carburization gear grinding ensures consistent tooth geometry and surface finish below Ra 0.8μm, which directly reduces running noise and extends time between maintenance intervals.
5. Flexible Ratio and Stage Options
Available in both single-stage and double stage planetary gearbox configurations, the EP-Double shaft planetary gearboxes series covers ratios from approximately 3:1 up to 4000:1. Whether the application requires fine speed control for a packaging line or extreme reduction for a mining drive, the modular stage design allows the right ratio to be selected without major re-engineering of the mounting arrangement.
4. How the Double Shaft Planetary Gearbox Works?
At the core of every double shaft planetary gearbox is the epicyclic gear train. The input shaft connects to the central sun gear. As the sun gear rotates, it drives a set of planet gears — typically three — that orbit around it while simultaneously meshing with the internal teeth of the ring gear. The ring gear is fixed to the housing and does not rotate. The planet carrier, attached to the orbiting planets, becomes the output mechanism.
What distinguishes the EP-Double shaft planetary gearboxes series is the extension of this output through two shaft stubs — one on each side of the housing — both keyed and toleranced to the same shaft standard. Both shafts rotate at identical speed and torque, making them ideal for driving paired screws, rollers, augers, or conveyor drums that must remain perfectly synchronized. The coaxial nature of the planetary arrangement keeps input and output centered, which also minimizes the bending moment on mounted equipment.
In a Double shaft planetary gearboxes variant, the output of the first planetary stage becomes the input to the second, achieving significantly higher reduction ratios while keeping the overall housing length compact. This staged approach maintains the high efficiency characteristic of planetary designs — typically 97% per stage — meaning minimal energy is lost to heat even under continuous-duty operating conditions.
Lubrication is handled by an oil bath or grease-packed system depending on the frame size, with oil level indicators and drain plugs positioned for accessible servicing without removing the unit from its mounting.
5. Double shaft planetary gearboxes Material Construction
Material selection in the EP double planetary gearbox is deliberate — chosen not for cost reduction but for performance retention across extended duty cycles. Every component in the drivetrain load path is manufactured from verified-grade materials with documented heat treatment traceability.
Housing and Structural Body: The main housing is cast from HT250 grey iron or ductile iron (nodular cast iron), which provides excellent rigidity under bending loads while absorbing vibration from abrupt torque changes. The foot plate is integrally cast — not bolted on — ensuring structural continuity and eliminating a common failure point found in aftermarket foot-mount retrofit solutions.
Gear Set: All sun gears, planet gears, and ring gears are machined from 20CrMnTi high-alloy steel. After initial machining, gears undergo carburization to create a hard, wear-resistant surface layer (58–62 HRC) while preserving a tough, impact-absorbing core (33–48 HRC). Each gear tooth is finish-ground to ISO 1328-1 Grade 5–6 — a precision level that keeps backlash minimal and surface contact noise well within acceptable industrial limits.
Shafts and Carriers: Output shafts are produced from 42CrMo alloy steel — a material known for its strength-to-fatigue ratio in rotary applications. Planet carriers are precision-bored and pin-fitted to maintain consistent planet gear positioning across the operating temperature range.
Bearings and Seals: Rolling element bearings are selected to handle both the radial loads from gearing forces and the axial loads that can develop in inclined or vertically-mounted installations. Shaft seals are oil-resistant and rated for continuous service in dusty or humid environments, which is particularly relevant for installations near Barranquilla's port facilities or in the interior mining corridors of Antioquia.
6. Application Scenarios
The double shaft planetary reducer in the EP series is specified across a wide range of driven-equipment categories. The following industries in Colombia and neighboring markets represent the most common deployment environments — each placing distinct demands on the gearbox that this series is specifically designed to meet.
Mining & Mineral Processing
For operations running jaw crushers, cone crushers, and belt feeders — particularly prevalent in Colombia's carbón and nickel extraction zones — the double shaft planetary gearbox mining Colombia variant delivers consistent high torque under shock-load conditions. The dual output simplifies twin-roller crusher drives, removing one mechanical coupling point from the drivetrain.
Conveyor & Material Handling
Long horizontal and inclined belt conveyors often require drives at both head and tail ends. The double shaft planetary reducer conveyor belt Colombia configuration allows a single gearbox to drive both drum ends in a symmetrical arrangement, ensuring even belt tension and reducing belt wear. This is standard practice in quarry operations near Bogotá and the Eastern Cordillera.
Cement & Building Materials
Kiln drives, cement mill drives, and raw material roller presses all demand sustained heavy torque with minimal maintenance interruptions. The double shaft planetary gearbox cement industry Colombia designation reflects this gearbox's suitability for continuous 24-hour operation under the thermal and mechanical stress of clinker grinding and kiln rotation.
Agro-Industry & Sugar Processing
Sugar cane mills, feed pellet presses, and grain auger systems require a double output shaft gearmotor agro-industry Colombia that can handle sticky, fibrous material loads without stalling. The EP series handles the high starting torque typical of loaded conveyors at harvest time, and is compatible with variable frequency drive (VFD) control panels for energy savings.
Construction & Concrete Industry
Concrete mixer drives and aggregate batching plant conveyors benefit from the foot-mounted format's easy floor installation. The compact body fits into mixer drum frames where space is limited, while the dual shaft output enables simultaneous drive of mixing blades without a secondary countershaft or chain drive.
Textile & Chemical Processing
For winding, dyeing machines, and chemical reactor stirrers, precise low-speed high-torque drive is required at consistent output. The double stage planetary gearbox configuration reaches the very high ratios that these applications demand, while maintaining quiet operation compatible with factory floor noise regulations in Colombia's industrial zones
7. Regulatory Compliance & Industry Standards
Industrial machinery and mechanical power transmission equipment sold in Colombia and the broader Latin American market is subject to a layered set of national, regional, and international regulations. Buyers specifying a double shaft planetary gearbox supplier Colombia should confirm that the product they procure complies with the applicable frameworks governing machinery safety, noise, and environmental protection.

Frequently Asked Questions
Q1. What is a double shaft planetary gearbox and how does it differ from a standard single-output planetary reducer?
A double shaft planetary gearbox extends the planet carrier output through both ends of the housing rather than just one. Both output shafts rotate at the same speed and deliver the same torque, allowing a single gearbox to drive two separate machine elements simultaneously — such as both drums of a conveyor or both screws of a twin-screw extruder. A standard planetary reducer exits through one shaft only, requiring an external splitter box if dual output is needed. The EP series integrates this capability directly into the gearbox housing.
Q2. What lubrication does a high torque double shaft planetary gearbox require, and how often should it be changed in Colombian climate conditions?
Larger frame sizes use an oil bath lubrication system with ISO VG 220 or VG 320 gear oil depending on ambient temperature and input speed. In Colombia's highland climate (Bogotá at 2,600 m elevation) where ambient temperatures average 14–18°C, VG 220 is generally appropriate for standard gearboxes. In coastal or valley installations (Barranquilla, Cali) at higher ambient temperatures, VG 320 is recommended. For a high torque double shaft planetary gearbox Colombia under heavy-duty cycling, the first oil change is recommended after 500 hours of initial operation, with subsequent intervals of 5,000 hours or annually — whichever comes first. Never allow the gearbox to start with oil temperature below 0°C without preheating.
Q3. How do I calculate the correct gear ratio for a double output shaft gearbox driving a conveyor belt system in Bogotá?
The ratio is determined by the required output shaft speed divided into the motor input speed. For example, if your motor runs at 1,450 RPM and the conveyor drum must turn at 29 RPM, you need a ratio of 50:1. For a double shaft planetary reducer Bogotá application, you should also confirm that the output torque at that ratio — calculated as (motor torque × ratio × efficiency) — meets or exceeds the maximum running torque plus an appropriate service factor for your load type. Our engineering team can assist with this calculation at no charge.
Q4. What does foot-mounted mean for a planetary gearbox, and what installation advantages does it offer on industrial sites in Medellín?
Foot-mounted refers to an integrally cast base plate on the gearbox housing that allows the unit to be bolted directly to a structural surface — a machine frame, concrete foundation, or steel skid. For double shaft planetary gearbox Medellín installations, particularly in facilities where vertical height is constrained, the foot mount keeps the drivetrain close to the floor, simplifies shaft alignment to the driven equipment, and eliminates the need for a separate mounting bracket or torque arm that is typically required with hollow shaft or shrink disc output configurations.
Q5. What gear ratio range is available for a dual shaft planetary gearbox used in crushing applications in Bucaramanga?
For a planetary gearbox dual shaft Bucaramanga crusher application, the EP series covers ratios from 3:1 in single-stage configurations up to 4,000:1 in multi-stage combinations. Jaw crushers and cone crushers typically require ratios in the 6:1 to 50:1 range to step the motor speed down to the crusher main shaft speed while multiplying torque. The exact ratio selection depends on the crusher eccentric shaft speed requirement and the available motor. We can confirm the optimal frame size and ratio within 24 hours of receiving your motor nameplate and crusher speed specification.
Q6. How do I get a quote for a double shaft planetary gearbox for sale in Cali Colombia for a sugar mill application?
To receive an accurate quotation for a double shaft planetary gearbox for sale Cali Colombia for sugar mill service, you will need to provide the input power (kW), motor speed (RPM), required output speed or ratio, and the service factor applicable to your crusher or mill type. Sugar milling applications typically involve high shock loads at startup and during cane feeding, which require a service factor of 2.0 or higher. Submit your specifications through our inquiry form or contact our Latin America sales team directly, and we will return a written quotation with dimensional drawings within two business days.
Q7. Is repair service available for a damaged double shaft planetary gearbox in Colombia, and what does it typically involve?
Yes. Double shaft planetary gearbox repair Colombia services are available for units within the EP-Double shaft planetary gearboxes and for equivalent third-party planetary gearboxes with comparable internal geometry.
