Product family
EP600-series wheel drives with rotating flange support for wheels and drums, covering listed-model torque and ratio selections.
Category overview
Wheel drives place planetary reduction near the wheel or drum interface. Selection must coordinate output torque, wheel radius, vehicle speed, radial load, braking and the hydraulic or electric input.

Application context
Industrial vehicles, transport platforms and special mobile equipment.
Rotating drums and cable-handling mechanisms using a flange-supported output.
Compact vehicle layouts where drive, brake and wheel support must share a limited envelope.
Interfaces deserve the same discipline as the internal gearing. Define the input driver, adapter, shaft or spline, output shaft or flange, pilot diameters, fastener pattern, load application point, and the space available for installation and service. When the drive supports external radial or axial load, show the force direction and distance from the bearing reference. When the drive couples to a wheel, track sprocket, slew ring, rack pinion, pulley, or drum, include the mating geometry. Those details often decide whether a model that looks adequate for planetary wheel drives is actually suitable in the machine. Thermal and lubrication questions should be resolved before release rather than after a prototype runs hot. State ambient temperature, operating hours, input speed, duty cycle, mounting orientation, expected ventilation, and whether the gearbox is inside an enclosure. Confirm lubricant type, viscosity or manufacturer-approved grade, fill quantity, fill and drain access, and any oil-circulation or cooling requirement. The purpose is not to add paperwork; it is to ensure that the selected arrangement can maintain a stable oil film and acceptable temperature while delivering a defensible family-level shortlist. Acceptance criteria should be tied to function. For a precision axis, backlash, torsional stiffness, runout, pitch or tooth accuracy may matter. For mobile equipment, brake release, holding behavior, sealing, valve integration, and output-bearing loads may dominate. For process machinery, temperature, leakage, vibration, shaft loading, and service access may be more important. Define which characteristics are controlled on the drawing, which need inspection records, and which are verified by a functional test. This evidence-based approach reduces ambiguity around planetary wheel drives and gives both buyer and supplier the same release target.
When information is incomplete, mark the gap instead of replacing it with an invented value. A useful RFQ can still proceed with an application sketch, motor data, target motion, estimated duty, and the known interfaces, provided the missing confirmation is visible. The supplier can then return a data-request list or a provisional configuration. For Planetary Wheel Drives, the key is traceability: the final model, ratio, mounting, options, and acceptance method should all map back to the operating conditions that justified them. A final cross-check should ask what happens if one assumption changes. Consider a higher start frequency, a larger wheel or pinion radius, a warmer ambient condition, a different mounting orientation, or a new external load. If any of those changes can invalidate the selection, record the dependency in the quotation notes. That practice is particularly valuable for planetary wheel drives, because it prevents a technically correct selection from being copied into a second machine with a materially different duty. The released configuration should therefore be treated as application-specific, even when it belongs to a standard product family. Planetary Wheel Drives should be treated as an engineering decision about planetary wheel drives, not as a lookup exercise. The first objective is an application-specific model choice. Begin with the machine function and document the operating point in units that can be checked independently: torque at the driven member, rotational or linear speed, the timing of acceleration and deceleration, and the duration of normal and peak conditions. For planetary wheel drives, that sequence matters because the same nominal power can produce very different gearbox loads when ratio, inertia, start frequency, or external forces change. The working record should explicitly cover wheel or drum radius, ratio, external loads, brake and valves, design a/b.
A strong review separates source-backed product data from application assumptions. Published model values can define a feasible envelope, but the machine-side calculation remains the buyer or system designer input until it is confirmed. In the context of planetary wheel drives, record which values came from a controlled drawing or product source, which were calculated from machine geometry, and which remain provisional. This prevents unclear acceptance after order. It also makes later changes easier to manage because an engineer can see whether a revised motor, wheel radius, duty cycle, or mounting arrangement changes the gearbox requirement or only the surrounding interface. The selection should be checked at more than one operating condition. A normal production point establishes continuous demand; an acceleration or start point establishes short-duration torque; a jam, emergency, wind, slope, or braking event may establish a separate peak. Each condition should carry a duration and expected frequency. That distinction is especially important when reviewing planetary wheel drives, because mechanical capacity, bearing life, brake capacity, and thermal capacity do not respond to load in the same way. A concise duty table is more useful than a single oversized safety factor, and it gives the supplier a reproducible basis for confirming traceable acceptance evidence. Interfaces deserve the same discipline as the internal gearing. Define the input driver, adapter, shaft or spline, output shaft or flange, pilot diameters, fastener pattern, load application point, and the space available for installation and service. When the drive supports external radial or axial load, show the force direction and distance from the bearing reference. When the drive couples to a wheel, track sprocket, slew ring, rack pinion, pulley, or drum, include the mating geometry. Those details often decide whether a model that looks adequate for planetary wheel drives is actually suitable in the machine.
| Data group | Information to provide |
|---|---|
| Wheel or drum radius | Convert required tractive force into output torque at the actual radius. |
| Ratio | Match maximum travel speed and motor operating range. |
| External loads | Confirm radial and axial loads transmitted through the wheel or drum. |
| Brake and valves | Specify parking, holding and overcenter-control needs. |
| Design A/B | Select the mounting arrangement that matches the surrounding structure. |
That depends on the mounting and bearing arrangement. External load paths must be confirmed for each application.
Some arrangements can be adapted, but flange geometry, speed, load and brake requirements must be checked separately.
