Excellent quality 12v Dc Mini Hydraulic Power Unit - GRS series – Guorui Detail:
GENERAL INFORMATION
Cycloidal gear motors convert hydraulic energy (pressure, oil flow) into mechanical energy (torque, speed). Cycloidal gear motors operate on the principle of an internal gear (rotor) rotating within a fixed external gear (stator). The internal gear transmits the torque generated by the application of pressure from hydraulic oil fed into moto which is then delivered via the motor’s output shaft. Cycloidal gear motors have high starting torque and constant output torque at wide speed range.
DISTIBUTORVALVE
GR, GRS series motors have spool valve: the distributor valve has been integrated with the output shaft. The cardan shaft rotates distributor valve and transfers mechanical energy from gerotor set to output shaft. The valve has hydrodynamic bearings and has infinite life when load ratings are not exceeded.
GEAR WHEEL SET
There are two forms of gearwheel set:
Roll-gerotor set has teeth fitted with rollers. The rollers reduce local stress and the tangential reaction forces on the rotor reducing friction to a minimum. This gives long operating life and better efficiency even at continuous high pressures.
Roll-gerotor sets are recommended for operation with thin oil and for applications with continually reversing applications with continually reversing loads. GR, GRS series motors have roll-gerotor set.
