Embodiment

[0026] Such as Figures 1 to 3 shown. The invention discloses a non-traditional processing method for an RV cycloidal gear, comprising the following steps:

[0027] Step 1: Select the metal round blank as the original blank;

[0028] Step 2: Normalize the raw material described in step 1, that is, heat it to 900°C-920°C, keep it warm for 1 hour, then quickly cool it to 580°C-600°C and keep it warm for 1 hour, then take it out of the furnace Cool to room temperature;

[0029] Step 3: Carry out central circular hole 1 processing to the raw blank after normalizing treatment in step 2, then locate with the central circular hole, carry out slow wire-feeding cutting cycloid 3 to the raw blank, obtain cycloidal gear blank (such as figure 2 shown);

[0030] Step 4: The cycloidal gear blank obtained in Step 3 is subjected to stress-relief annealing treatment at a temperature of 580°C-600°C, after a holding time of 7 hours, and then cooled to 180°C-200°C with the furnace, and then ...

Abstract

The invention discloses a non-traditional machining method of a RV cycloid gear. The method comprises following steps: metal round blank material is selected as raw material and is subjected to normalizing and low-speed wire cutting and slicing; a via hole of the workpiece is processed using a cycloid as the reference; the workpiece is subjected to stress relief annealing and quenching; then the workpiece is subjected to drawing temper, finishing and abrasive flow polishing. According to the method of the invention, low-speed wire cutting is adopted to process gear cycloid and abrasive flow is adopted to polish cycloid gears; after processing, the surface roughness of the cycloid gears is low and the dimensional accuracy is high. Compared to the traditional rough turning-fine turning-gear hobbing-gear shaving-gear grinding process, the production efficiency is significantly improved, and the high cost of high accuracy machine tools required in rough turning-fine turning-gear hobbing-gear shaving-gear grinding process; the method has good production prospect.

Description

technical field [0001] The invention relates to the field of gear processing, in particular to a non-traditional processing method for RV cycloid gears. Background technique [0002] The development of the robot industry has far-reaching significance for promoting the transformation and upgrading of traditional industries and realizing innovation-driven development. With the robot industry included in the key strategy of "Made in China 2025", the "Thirteenth Five-Year Development Plan for the Robot Industry (Draft for Comment)" led by the Ministry of Industry and Information Technology has been drafted, and China's robot industry has ushered in a major strategic development. opportunity. Statistics show that in the past five years, China's robot market has grown at an average annual rate of 36%. Last year, the sales of industrial robots in the Chinese market soared by 54%, reaching 56,000 units, becoming the world's largest industrial robot demand country. [0003] The R&D...
