Network optimization information:

The high-voltage motor A6VM adopts a conical plunger (conical angle A=2-4), and its head structure is a ball head structure. The return plate is used to contact the flange surface of the transmission shaft, which can reduce the contact stress and withstand greater working pressure. The hydraulic oil can also leak along the sliding surface through the central hole of the main plunger and the central hole of the transmission shaft, so as to ensure a layer of oil film lubrication between the transmission shaft and the bearing and reduce friction and wear. The plunger with cone structure simplifies the process structure, reduces the processing cost, reduces the volume and improves the quality.

Plunger diameter d, plunger distribution circle radius r and plunger number z are mutually limited and related to the structure type. Cycloidal hydraulic motor mb4 In order to ensure the performance, strength and rigidity of the structure, BMV cycloidal hydraulic motor Generally, the sketch method is used to calculate the most compact structure size, while considering the improvement of technology. The plunger motor designed in this paper is a semi axial structure, and the number of plungers z=7 can make the motor structure more compact and reduce flow fluctuations.

Now most of the cylinders are bimetallic. The outer layer is made of high-quality steel, and the spherical surface of its hole, plunger and port plate is a copper layer High torque cycloidal hydraulic motor It is a cast copper alloy. So the process requirements are:

Cast copper alloy shall be consistent with the designed chemical composition and mechanical properties;

The cast copper layer shall be free from sand holes, looseness, severe segregation and other defects;

The copper layer shall be firmly combined with the base material without layering;

The dimensional tolerance, cylindricity, surface roughness, diameter tolerance of seven hole circle and bisector tolerance of the matching hole between the cylinder block and the plunger must meet the design requirements.

The diameter, sphericity, runout and roughness of the ball surface equipped with the orifice plate shall meet the design requirements.
