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
Application Areas
-
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.
