Precise component adaptation matching process technical method

Abstract

The invention discloses a precise component adaptation matching process technical method, which comprises the following steps of: adapting a front cycloidal gear and a rear cycloidal gear on the basisthat the phase difference of the front cycloidal gear and the rear cycloidal gear is abs (Be-Ce) and the tooth root difference of the front cycloidal gear and the rear cycloidal gear is abs (Bb-Cb);on the basis that Aa-(Bb + Cb) / 2-Da * 2-Fa * 2 meets the matching coefficient of the cycloidal gear, the needle shell and the rolling needle, enabling the cycloidal gear, the needle shell and the rolling needle to form an adaptive combination; on the basis that Db1 + 2 * Ga-Bc, Db2 + 2 * Ga-Bd, Dc1 + 2 * Ga-Cc and Dc2 + 2 * Ga-Cd meet the matching coefficients of the eccentric shaft, the cycloidalgear and the retainer at the same time, enabling the eccentric shaft, the cycloidal gear and the retainer to form an adaptive combination; selecting an eccentric shaft according to the minimum weightprinciple, wherein the total weight of eccentric shaft matching is Qz + m * Qc. Waste of precision components can be effectively reduced, the consistency of products is improved, and then the productperformance is improved.

Description

technical field [0001] The invention relates to the technical field of precision component selection and matching, in particular to a precision component matching and matching process technical method. Background technique [0002] RV reducer is a product of the precision machinery industry supporting system. It is assembled by high-precision components. It has the characteristics of low backlash, high precision, high efficiency and high speed ratio, so it is widely used in high-precision large deceleration of robot joints and machine tools. than the occasion. The overall accuracy of the reducer is less than 1 arc minute. According to the minimum rotation diameter of the RV reducer of 100mm, the conversion clearance of the reducer needs to reach 0.02mm. In the actual operation process, from input to output, the transmission needs to be matched by the needle shell cycloid and the needle roller. For the fit of cycloid eccentric shaft and cage bearing and the fit of eccentric ...

Problems solved by technology

[0003] Under the existing processing technology conditions, it is difficult to control the precision of parts at the micron level, and it is difficult to effectively guarantee the yield rate. The following defects are prone to occur in the assembly process: 1) The waste of precision components, the processing of precision components needs to be controlled In the precision range of the national standard 2-3 level, the requirements for equipment, personnel, etc. are extremely high, and the waste of precision components will be huge; 2) The consistency of the product is poor, and the cooperation of product components cannot be consistent, which will cause the RV to decelerate Under different assembly conditions, the performance of the product varies greatly, which will eventually cause a great waste of products and performance; 3) Due to the assembly process requirements of the reducer, it will put forward high requirements for equipment, personnel quality, and technology. As a result, the cost of the reducer is greater than its own value, and the cost is inflated
