A high mounted hydraulic motor with balanced negative pressure, which is used to improve the low-speed gear in the current sales market Large torque Hydraulic motor In the current situation, a hydraulic motor with high efficiency (mechanical energy, high capacity efficiency), high pressure, high installation and further improved service life was invented. The basic principle of negative pressure equalization was flexibly used in this motor to improve the working characteristics of the motor.
In fact, we can grasp the characteristics of this motor according to the following four illustrations.
1、 In the case of our motor feeding fluid in cavity B, the pressure oil is fed from one plane of the oil distribution plate. According to the main oil passage to the other plane, because there is an annular oil groove, the pressure oil can be evenly distributed on the plane of the oil distribution plate, so it can ensure that the sliding friction between the two surfaces can be reasonably reduced when the oil distribution plate and the parallel surface of the surface are working, The leakage of pressure oil is very small, and the capacity and efficiency are further improved.
2、 In our Hydraulic motor of cone crusher In the case of cavity A, the pressure oil is fed from the round surface of the oil distribution plate. According to the main oil passage to the two planes, there are safety channels to reach the two planes of the motor immediately after the high pressure oil enters from the oil inlet hole. The oil in one plane immediately reaches the working cavity of the motor, and the oil in one plane flows to the oil inlet according to the gap between the oil distribution plate and the oil inlet, Therefore, the pressure oil can also have a symmetrical effect on the plane of the oil distribution plate, ensuring that the parallel surface between the oil distribution plate and the surface can reasonably reduce the sliding friction between the two surfaces during fitness exercises. The leakage of the pressure oil is very small, and the capacity efficiency is further improved.
3、 First, 20CrMnTi is selected as the material of plunger pump, which is suitable for making key parts that can bear heavy load, impact and friction.
Open a dialog box with a large total area on the mating surface between the plunger pump and the roller bearing surface, so that the high pressure oil can flow here and cause a driving force to the roller bearing surface, reducing the sliding friction of the two surfaces, thus achieving the balance of negative pressure, making the motor more stable and smooth during operation, and improving the mechanical energy.
Because the roller bearing is simple in structure, convenient in production and processing, and does not have stress points, it is more reliable. Therefore, the structure of roller bearing and plunger pump can bear a great load capacity and improve the working efficiency of the motor.
IV High speed high torque hydraulic motor During operation, high speed rotation and pressure will cause great deformation between the engine cylinder block and the housing, which will damage the motor. Therefore, our motors use new secret aluminum alloy materials, and immediately open oil grooves in the holes matching with the engine cylinder block, so that high pressure oil can flow into the housing oil groove, achieving the actual effect of negative pressure balance. It has got rid of the defect of oil-free bearings widely used in basic motors (oil-free bearings are very easy to deform under the condition of high speed ratio). On the one hand, it can improve the motor speed ratio, on the other hand, it can also improve the service life of the motor at a very large level.
