Shaft material selection

The main shaft of the motor supports the cylinder body and outputs the torque with the help of the rotation of the cylinder body. There are bearings, sealing rings, compression springs, etc. on it to cooperate with it, and the force is complex. To estimate its size, first select the material.

The main shaft transmits torque, OMS cycloidal hydraulic motor There are also eight ball sockets connected with the plunger and the ball head of the central shaft respectively, one of which is matched with the skeleton oil seal, so it is required that:

The size tolerance, radial runout, roughness, etc. of the outer circle shall meet certain requirements when matching with the bearing;

2. One section matched with framework oil seal, OMP cycloidal hydraulic motor Its roughness is required to reach 0.2 um Ra, and no spiral knife marks are allowed;

There are requirements for the diameter tolerance of the ball socket distribution circle of the spindle disk and the seven equal division of the ball socket.

Nitrogen steel 38CrMoA1A can be used under the condition of high wear resistance, high strength and minimal heat treatment deformation. Start mechanical performance parameters.

Residual shaft design

Through the matching of various parts of the main shaft, the main shaft drawing is drawn as follows. Its length and diameter are determined by the matching size, such as the matching with standard parts such as bearings and sealing rings.

Volume V Hydraulic motor The volume of liquid discharged every week is called volume. The volume depends on the structure of the motor. The measuring motor has the same volume, and the measuring motor has the same volume.

The flowmeter q consists of theoretical and practical parts. When the hydraulic motor forms a certain speed in unit time, the flow rate q required due to the change of the volume of the closed chamber is equal to the product of the displacement of V and the speed n.
