[0026] figure 2 It shows a schematic cross-sectional view of a non-circular planetary gear hydraulic motor system in coal mining machinery according to another embodiment of the present invention. Such as figure 2 The shown non-circular planetary gear hydraulic motor system in coal mining machinery also includes an end cover 206 and a flow plate 207. One side of the non-circular external gear is an end cover, and the other side of the non-circular external gear It is a distribution plate 207 , the output shaft 204 runs through the middle part and the end cover of the non-circular external gear, and one end of the output shaft is connected with the distribution plate 204 .

[0027] The distribution plate 204 is provided with a distribution hole.

Embodiment 3

[0029] The non-circular internal gear, the end cover and the flow plate are fixed together to form the housing of the motor, and the non-circular external gear is connected with the output shaft to realize the output of the motor torque. During the working process of the motor, the working fluid is input from the distribution plate through the distribution hole into the closed working chamber composed of non-circular external gears, planetary gears, non-circular internal gears, end covers and distribution plates, and its pressure pushes the cylindrical planetary gears to produce revolution and rotation. , and drives the noncircular external gear to rotate. At this time, the volume of the airtight working chamber changes. The distribution plate can ensure that the liquid inlet hole is opened and the liquid discharge hole is closed when the volume of the sealed working chamber reaches the minimum, and the liquid discharge hole is opened and the liquid inlet hole is closed when t...

Description

technical field [0001] The invention relates to the technical field of coal mine machinery, in particular to a noncircular planetary gear hydraulic motor system in coal mine machinery. Background technique [0002] The non-circular planetary gear hydraulic motor is a new type of low-speed high-torque hydraulic motor. Due to the low speed and high output torque, the low-speed high-torque hydraulic motor can generally directly drive the load without a deceleration device. It has the advantages of stable low-speed operation, high starting efficiency, small moment of inertia, short acceleration and braking time, compact structure, and flexible layout. And other advantages, so it has been more and more widely used in engineering equipment. [0003] At present, the low-speed high-torque motors widely used in domestic and foreign markets have the problem that the transmission chain is complex, consisting of several plunger unit cylinders, the structure is relatively complicated, t...
