Description
BMT series orbital hydraulic motor is an advanced hydraulic motor with end-face flow distribution structure. This series of motors use a column-mounted rotating stator pair, which has the characteristics of high working pressure, high working efficiency, good efficiency retention of the whole machine and long working life. On the basis of standard structure, multi-functional variant design can be carried out according to user requirements. Its characteristics:
• The use of advanced stator parameter design, low starting pressure, high efficiency and good retention.
• High working pressure and large output torque. Tapered roller bearing structure, bearing shaft, radial load capacity is strong, so that the motor can directly drive the working mechanism, the scope of use is expanded.
• Advanced end face flow distribution structure, so that the motor with high precision, wear after the automatic compensation function is strong, to ensure high volumetric efficiency, motor long life, to ensure that the motor speed is stable, smooth load speed characteristics.
