Product details

BM6 series orbital hydraulic motors are designed with geroler element and pressure balanced valve plate. It has the following structure assembly, see Drawing 1, and features of performance:
· Advanced design of disc valve, realizing small size, compact structure and higher distributing accuracy.
· Adopt geroler element, ensuring higher mechanical efficiency and longer lifttime under high back pressures.
· Adopt pressure balanced organ, balancing both axial clearance between balanced valve and disc valve and axial clearance between disc valve and auxilliary valve and balanced valve could automatically move to the left side and then ensuring the higher volumetric ficiency of the motor.
· Adopt double conical rolling bearings to the output shaft in order to guarantee he higher radial load of the motor, which ensures the motor could be used to directly drive the orking organ, needless to add any other bearings, simplifying the whole systems.
· Adopt double deep groove ball bearings, ensuring much more radial load and axial load, reducing friction forces and improving the mechanical efficiency.
· Special splines design of the cardan shaft ensures the good performances on stable between rotation speeds and loads and speed could be easily adjusted. It adopts 2 cardan shafts, ne is long shaft particular for torque transmission, the other is short shaft particular for completing he oil distribution during the synchronous rotations of rotor and distribution valve, which only needs a little moment, reducing the frictions and guaranteeing the higher oil distribution accuracy.
· Advanced design of dynamic oil seals, framework oil seal for shaft rotations, and O-rings which could bear 5Mpa back pressures normally.
· A variety of connection types of flange, output shaft and oil port:
    Standard motor: Mounting flange is near at the end of the output shaft, being a usual connection mode.
    No-bearing motor: It has no output shaft and bearings. The torque could be outputed through shaft coupling with external splines, which is used for special applications that has higher demand on the compact volumes. It demands the right internal splines which could match with the external splines of shaft couplings when it’s installed with other parts.
