Key Features of BM6 Series Hydraulic Motors
-
High-performance heavy-duty design, upgraded from the BM5 series, adopting advanced precision end face distribution technology and internal curve gear meshing principle, with higher power density and load-bearing capacity, fully meeting the high-pressure and heavy-duty operation needs of large-scale equipment[4].
-
Enhanced high-precision end face distribution structure with automatic wear compensation function, optimized internal flow channel design, effectively reducing internal hydraulic loss, the volumetric efficiency can reach 86%-93%, and the total efficiency is higher than the industry average, ensuring ultra-smooth operation at low speed and long-term stable operation under heavy load.
-
High-strength reinforced double-row tapered roller bearings on the output shaft, adopting precision machining, heat treatment and anti-corrosion technology, which can bear larger static and dynamic radial loads than the BM5 series, with strong impact resistance (up to 150% of the rated load), greatly extending the service life of the motor[5].
-
Integrated intelligent monitoring and protection function, optional built-in pressure and temperature sensors, real-time monitoring of motor operation status, timely early warning of overload, overheating and other faults, reducing maintenance costs and improving equipment operation safety[5].
-
Excellent low-pressure start performance and large starting torque (T启=(2.2~3.2) T额), which can realize stable start and continuous operation under low oil pressure and heavy load conditions, with fast response speed and strong adaptability to complex working conditions.
-
Flexible compatibility and wide adaptability, compatible with the mounting flanges, output shafts and oil port types of the BM5 series, supporting customized design of pressure, torque and control mode according to user needs, easy to replace and maintain, and interchangeable with mainstream high-performance hydraulic motor models.
Performance Characteristics
Application Areas
-
Mining machinery: Large coal shearers, roadheaders, mine hoists, crushers and other equipment, adapting to the harsh and heavy-load working conditions of mining sites, with strong impact resistance and long service life[5].
-
Construction machinery: Large hydraulic excavators, heavy-duty rollers, large cement mixers, tower cranes and other equipment, adapting to large-scale construction projects that require high-pressure and heavy-duty operation.
-
Industrial equipment: Large winding machines, high-pressure vulcanizing machines, large injection molding machine preplasticizing screw drives, heavy-duty conveyors, suitable for high-efficiency and heavy-duty industrial production scenarios[4].
-
Marine equipment: Large ship anchor winches, marine cranes, offshore operation platforms and other equipment, with excellent corrosion resistance and load-bearing performance, adapting to the complex marine working environment.
-
Other fields: Large-scale agricultural machinery (heavy-duty combine harvesters), heavy-duty environmental protection equipment, large-scale port machinery, meeting the high-performance and heavy-duty operation needs of various large-scale equipment.
