Key Features of BM5-V Series Hydraulic Motors
-
Variable-displacement design, derived from the BM5 series, with advanced hydraulic variable control technology, realizing stepless adjustment of displacement (adjustable range 10%-100%), and flexibly matching speed and torque according to load changes, significantly improving energy efficiency and operation economy.
-
High-precision end face distribution structure with automatic wear compensation function, combined with variable control system, ensuring smooth operation at low speed, effectively reducing internal hydraulic loss, and the volumetric efficiency can reach 85%-92%, with excellent operation stability.
-
High-strength double-row tapered roller bearings on the output shaft, adopting precision machining and heat treatment technology, which can bear large static and dynamic radial loads, balancing variable performance and load-bearing capacity, and greatly extending the service life of the motor.
-
Optimized dual-seal structure, combining high-temperature resistant oil seal and dust-proof seal, with strong sealing performance, capable of withstanding high back pressure, and suitable for harsh working environments such as high temperature, dust, humidity and variable load operation.
-
Excellent low-pressure start performance and large starting torque (T启=(2~3) T额), which can realize stable start and continuous operation under low oil pressure conditions, and the variable system can quickly respond to load changes, adapting to complex working conditions.
-
Flexible compatibility, compatible with the mounting flanges, output shafts and oil port types of the BM5 series, supporting customized variable control modes (manual, electric or hydraulic control) according to user needs, easy to replace and maintain, and interchangeable with mainstream variable hydraulic motor models.
Performance Characteristics
The BM5-V series hydraulic motors are variable-displacement end face distribution orbital geroler hydraulic motors, developed for low-speed, heavy-duty operation scenarios that require flexible speed and torque adjustment. As a typical variable orbital geroler motor, it adopts internal curve gear meshing principle and advanced variable control technology to ensure efficient and stable power transmission. The displacement ranges from 80.3 cm³/rev to 1250.5 cm³/rev, covering a wide range of torque (205-2750 N·m) and speed requirements (5-850 rpm), and the maximum intermittent pressure can reach 21.0 MPa. The motor features stepless variable displacement, high energy efficiency, smooth operation, low noise, long service life and strong adaptability, and the total efficiency (actual output power and actual input power ratio) meets industrial standards, making it an ideal choice for heavy-duty applications that need load matching and energy saving.
Application Areas
BM5-V series hydraulic motors, as the variable-displacement version of the BM5 series, are widely used in various industries requiring flexible speed regulation and load matching due to their excellent variable performance and reliable operation, including:
-
Construction machinery: Hydraulic excavator travel and slewing drives, large rollers, heavy-duty cement mixers, crane luffing mechanisms, adapting to complex construction conditions that require frequent speed adjustment.
-
Industrial equipment: High-load winding machines, conveyor speed regulation systems, injection molding machine preplasticizing screw drives, high-pressure vulcanizing machines, suitable for equipment that needs stepless speed regulation and load matching.
-
Marine equipment: Ship anchor winches, net hauling equipment, steering systems, marine crane drives, with excellent corrosion resistance and variable speed performance, adapting to the complex working conditions of ships.
-
Mining machinery: Coal shearers, roadheaders, mine hoists, adapting to the variable load working conditions of mining sites and realizing energy-saving operation.
-
Agricultural machinery: Large combine harvesters, heavy-duty rotary tillers, high-power irrigation equipment, realizing stepless speed regulation according to different working conditions and improving operation efficiency.
Model Coding Explanation
The model coding of BM5-V series hydraulic motors is based on the BM5 series, adding the “V” identifier to indicate the variable-displacement version, which is composed of 7 parts, clearly indicating the motor type, variable mark, displacement, output shaft type, flange type and oil port type. For example, “BM5-V 500 H4 A Y5” means:
-
Type: BM5-V (variable-displacement end face distribution orbital geroler hydraulic motor)
-
Variable mark: V (indicating the variable-displacement version of BM5 series, with stepless displacement adjustment function)
-
Displacement: 500 (corresponding to 501.0 cm³/rev)
-
Output shaft type: H4 (40mm rectangular spline, 8-40×35×7)
-
Flange type: A (large flange with 4×18mm mounting holes, φ160mm spigot)
-
Oil port type: Y5 (inlet and outlet M18×1.5, drain port M14×1.5)
