DRB rotary motor
Features are as follows: small volume, large power, stable speed, with a large load, the maximum static load 3OKN, large working pressure, the maximum pressure can reach 25MPA;
- Imported thrust bearing, can withstand large axial load;
Can be used for excavators, truck cranes, port machinery, wood grabber, steel grabber, cane grabber forestry machinery grabber, light weight, convenient disassembly and assembly, simple operation; one
Set rotary lifting in one, in the use of the process will not appear the situation of winding hose;
Suitable for equipment with rotating action, wide range of use.
1. Because the piston and cylinder have no side force, the piston bottom design scheme is negative pressure balance, piston and engine crankshaft according to roller bearing torque, gear type hydraulic motor reduces the friction damage of the transmission system, so GM product series hydraulic motor has high mechanical efficiency, high starting torque (starting mechanical efficiency above 0.92).
2, the plane distribution device is simple and reliable, improve the sealing characteristics, so the pump hydraulic motor low speed reliability, less leakage, piston and swing cylinder with plastic piston ring seal no leakage, so it has a high capacity and high efficiency (up to 0.98).
3, because of the structure to reduce friction damage, improve the sealing characteristics, so low speed reliability is good, can be in 1r/min working condition stable operation, variable speed range (speed adjustment ratio can reach 1000).
4. Because the piston and roller bearings are firmly attached according to the spring, there will be no gap, so the hydraulic motor series of this product can run under pump condition, when the oil inlet hole is closed, the motor can run at high speed under free wheel condition.
