Description :

The crankshaft design radial piston hydraulic motor, by using static equilibrium structure on the hydraulic motor, reduce friction loss in the process of force, this unit has high mechanical efficiency (> 93%), With oil technology is simple and reliable, sealed performance is good, so it has the high volume efficiency (> 99). Due to the improvement of the organization to minimize friction losses and adopts the imported seal, and low efficiency, stable performance in Grimm/MIN mining can be stable operation, the speed under large scope (1-1000R/MIN).

 Main characteristics:

1.High mechanical efficiency.

2.High volume efficiency.

3.Hhigh torque.

4.Low speed.

GM series motors are a result of the many years of experience based on italy technology,and incorporate a number of design variations with respect to the technology intended to increase the strength of the motor casings and the load capacity of the internal dynamic components.The result is the series of motor with high continuous power ratings,both because of the reduced internal specific loads,and because of the high mechanical and volumetric efficiency that contribute in reducing the amount of heat produced and therefore also the negative effects associated with it.The main characteristics are as follows:

• The side loading between the piston and swiveling cylinder has been eliminated;the hydrostatic balance is built between the piston feet;the piston transmit load to the shaft via a rolling bearing.All above reduces the friction loss in the load transmission.Therefore GM series hydraulic motor features high mechanical efficency and high staring torque.
• Rotary axial distributor(patent technology)ensures simply and reliable performance,good sealing capability,low leakage.The plastic piston ring between pistons and cylinder reduces the leakage,so the volumetric efficiency of motor is very high.
• Due to reduced friction loss in structure and improved sealing capability,so the motor can operated at low speeds with a high degree of speed stablility,even if at 1r/min of speed.hereby the speed control range is wide(the speed control ratio is up to 1000)
• The pistons and bearing sleeve is matched well via supporting ring to eliminate the clearance.so the series motors can run in pump condition.When the inlet port and outlet port is closed,the motors could run in freewheeling condition.
• The working pressure of the series motor is very high,and the maximum pressure is up to 45Mpa.The motor also features light weight,small size and high specific power.
• Because of simple struture,reasonable design,and using large load capacity bearing,the series motors has many excellent features as follow good reliability,long lifetime and low noise.transmission shaft endure radial load.Circumrotate way could be reverse
