Embodiment 1

[0026] 1. The processing method of the stator:

[0027] In the present invention, two sets of high-precision powder metallurgy die-casting molds are manufactured according to the structure and technical parameters of the stator in the cycloid metering device, one of which is a die-casting mold for the stator, and the other is a fine-pressing shaping mold for the stator. The die-casting mold shaping mold is carried out by conventional methods of making molds. The mold material is made of mold steel and the like. Then choose the pressure-resistant and wear-resistant high-density powder metallurgy materials corresponding to the stator in the cycloid metering device, mix the powder metallurgy materials evenly, and die-cast the stator with a stator die-casting mold on a 500-ton hydraulic press. The above-mentioned die-cast stator is sintered at a high temperature of 1200 degrees for 30 minutes, and the performance required by the stator is obtained through sintering. The performan...

Description

Technical field: [0001] The invention relates to a method for manufacturing a rotor and a stator pair of a cycloid device, belonging to the technical field of mechanical manufacturing methods. Background technique: [0002] Before the present invention was made, in the prior art, the rotation and stator of the cycloid device used in the cycloid rotary valve type full hydraulic steering gear were carried out in the following manner. The rotor is ground by strong forming; the internal tooth profile of the stator is processed by forming tension broaching and inner cavity forming grinding, or by rotor forming grinder or cycloidal grinding machine, and the internal tooth profile of the stator is processed by a combined stator. Formed by boring studs. The process flow of rotor processing: steel material—sawing—cutting—drilling—spline broaching—shape broaching—heat treatment—grinding. Stator processing process: steel - sawing - cutting - drilling - shape broaching - heat treatmen...
