In recent years, the hydraulic motor with brachytely and big torsional moment has great changes, the new structure continuously appears. But, all the hydraulic motors can be divided into two broad categories of single and multi-role according to the role of the number of plunger in each turn. The motors also can be divided into radial and horizontal direction according to the arrangement of the plunger. And the radial motors can be divided into different types according to structure and the summon power way of the plunger.
No matter single and multi-role, the plug-hole of radial-piston hydraulic motor is equated by circle, arrayed radial. The plunger displaced by the impul of pressure oil, then the volume of the cylinder changed, the summon power formed the rotation of the motor, all of the above are the mechanism of action of the motors.
The rotor of the single role hydraulic motor has a circle of rotation, each plunger worker onc
scoiattolo四级成绩查询官网e reciprocation. The principal axis is eccentric axis in all the radial-piston hydraulic motors. The multi-role hydraulic motor had a guide rail curve, who numbers are the action times. The rotor had a circle of rotation, the plunger worker many times reciprocal at the same time. The radial motors can be divided into veral categories of plunger, ball blocker, blade.
The structure of the single-role motors is simpler, the machine element number of it is less, the technology is better, and the cost is less. But the structure dimension of the single-role motor is longer than the multi-role motor in the same displacement each turn (or output torsional moment), and the single-role motor also have fluctuation of the output torsional moment and rotary speed.The homonymy
high-pressure column tune of the single-role motor had major radial unbalance force that caus the brachytely stabilization of the motor became wor. Only increasing the capacity of the bearing, it can meet the requirements of the operating life of the bearing at the same time.
睡美人阅读答案教学方法Generally speaking, the speed of single-role motors is higher than the multi-role in the same displacement becau of the work feature of the single-role motors. The structure of the multi-role motors is complicated than single-role, the number of machine element is bigger as well. Some machine element needs some special equipment to process them. The heat treatment of the guide rail is more difficult. And the lection of the texture parameters in design is more difficult and harder. The cost is higher without a doubt.

But the multi-role motor output larger torsional moment and had lighter weight of unit power in the same working pressure. The radial force of hydraulic motor can completely equilibrate and had higher started torsional moment efficiency as long as lecting the suitable plunger number and action number. In abstract the pulsation work of output torsional moment would be zero if one lect guide rail curve reasonable and assign argument to the principle of non-pulsation in design. All of the can made it’s low speed stab ility better.快递惊魂

Multi-role within the curve of the radial piston hydraulic motor is divided into transmission plunger, beam transmission, wheel transmission .The most ud are Beam transmission and Wheel Transmission motor .the france Crane Park motor produces the most ,the Rated working pressure is 30 MPa in all the Low Speed and High Torque motors Crane Park motor has the highest working pressure Recently , end assignment wheel motors is developed ,and the function was greatly improved . In recent years, Accompanied by Ball Cypriot Vice static and dynamic pressure bearing theory developed, Multi-role Radial ball plug Hydraulic Motor Developed quickly , such as Japan’s HMA ries . Which are widely ud in engineering and architecture. The hydraulic motor with brachytely and big torsional moment , commonly can be designed into Rotating shell or Axis rotation ,they are named shell
