Product details

1. Basic Product Definition

The BM4 Cycloidal Motor is a heavy-duty cycloidal hydraulic motor, a high-performance Hydraulic orbit motor. It efficiently converts hydraulic energy into mechanical energy through a precision internal-meshing gerotor assembly. As a core power actuator for low-speed heavy-load scenarios in medium and large-sized hydraulic system, it features upgraded torque capacity and pressure resistance compared with the BM1 series, perfectly adapting to harsher heavy-duty industrial applications.

2. Core Structure & Working Principle

Core Structural Advantages

It adopts high-precision shaft/distributed end-face flow gerotor assembly with superior oil distribution accuracy. Double heavy-duty rolling bearings mounted on both ends of the output shaft can withstand massive combined radial and axial loads. Equipped with imported high-pressure shaft seals, it enjoys outstanding backpressure resistance and can be connected in series or parallel directly within the hydraulic system. Built-in automatic wear compensation units and bidirectional overload relief valves keep efficiency stable for long-term operation. Multiple options of flanges, output shafts and oil ports meet diverse installation requirements.

Operation Mechanism

High-pressure oil supplied by the hydraulic system flows into the motor's sealed chambers, driving the rotor to make eccentric orbital revolution inside the stator. The orbital motion is converted into low-speed high-torque rotation of the output shaft via transmission components. Forward and reverse rotation can be smoothly switched just by adjusting the oil inlet and outlet direction of the hydraulic system, with stable speed regulation and slight startup impact for continuous intensive cyclic operation.

3. Core Performance Advantages (Premium Hydraulic orbit motor Traits)

- Exceptional low-speed high-torque performance: Displacement ranges from 80 to 1250mL/r with maximum torque up to 2650N·m, capable of driving heavy loads without extra reducers, featuring low starting pressure and strong anti-overload capacity.

- Outstanding hydraulic system compatibility: High-backpressure seals support complex pipeline arrangement of the hydraulic system, flexible series-parallel connection to match conventional medium-high pressure pump stations and multi-circuit hydraulic schemes.

- Long service life & easy maintenance: The rotor-stator pair automatically compensates for wear to maintain stable performance in dusty and vibrating scenarios. Highly interchangeable spare parts cut long-term maintenance costs of the hydraulic system.

- Flexible installation: Multiple keyed/spline shafts, square/rhombic flanges enable seamless integration into large-scale hydraulic system for construction, mining, marine and other machinery.

4. Key Technical Specifications

- Displacement range: BM4-80 ~ BM4-1250 mL/r

- Continuous working pressure: 16~21MPa, peak shock pressure up to 25MPa

- Rated flow: 65~160L/min, matching the oil supply range of medium and large hydraulic systems

- Rotation speed: 5~650r/min, excellent stability under heavy low-speed conditions

- Torque range: 194~2650N·m, ideal for winch, travel and slewing heavy-duty drives

5. Application Fields

As a high-power standardized Hydraulic orbit motor, it is widely used in heavy-duty hydraulic system:

1. Construction machinery: Travel & slewing drives for medium-large excavators, attachment drives for loaders, heavy rotation units for aerial work platforms, hydraulic winches for small cranes;

2. Mining equipment: Traction drives for shearers, drilling machine actuators, hydraulic drive units for mine conveyors;

3. Agricultural machinery: Roller drives for large harvesters, seeder equipment, hydraulic units for farm dredging machines;

4. Special industries: Road milling & sweeping vehicles, high-torque plasticizing units for injection molding machines, marine anchor windlasses, fishing net winches, small transmission devices for petroleum machinery.
