A cycloidal tooth profile curve simulation method and system of a speed reducer

Abstract

The invention provides a cycloidal tooth profile curve simulation method of a speed reducer, which comprises the following steps of obtaining related motion data of cycloidal gear teeth of the speed reducer, and drawing an actual curve of the cycloidal tooth profile motion; according to the geometric structure of the speed reducer, obtaining a theoretical equation of the cycloid tooth profile curve and specification parameters in the cycloid tooth profile curve, and determining a calculation formula of correction parameters and simulation parameters; determining a current correction parametervalue, extracting a value of a specification parameter from the related motion data, calculating to obtain a specific value of a simulation parameter, and further simulating a theoretical curve of cycloidal gear tooth profile motion; comparing whether a distance difference value between the actual curve and the theoretical curve is greater than a preset threshold; if yes, modifying the current correction parameter value, and then continuing the simulation; otherwise, outputting a finally simulated theoretical curve. According to the implementation of the method, a plurality of characteristic parameters are formed for simulation by combining the reality and theory of the cycloidal gear teeth of the speed reducer, so that the simulation error is reduced, and the reliability, accuracy and high efficiency of data are improved.

Description

technical field [0001] The invention relates to the technical field of motion simulation of a reducer, in particular to a method and system for simulating a cycloidal tooth profile curve of a reducer. Background technique [0002] Since the end of the 1970s, with the rapid development of technology, reducers with miniaturization, high speed, low noise and high reliability have brought unprecedented power to various industries such as metallurgy, sewing and military. By the 1980s, the hard tooth surface technology researched abroad had become increasingly mature. For general-purpose reducers, in addition to the general use of hard tooth surface technology, its only development direction is modular design technology, aiming at pursuing high performance while reducing the variety, specifications and quantity of parts and blanks as much as possible to reduce costs , gain economies of scale. [0003] As we all know, in the reducer, the precision of the tooth profile of the cycl...

Problems solved by technology

If the deviation of the cycloid tooth profile fitting is too large, noise will be generated when the reducer is running, and it will generate heat at the same time, which will increase the loss of parts and reduce the service life of the reducer

[0004] Especially in recent years, with the rapid development of modern design methods and computer technology, software system development plays an incomparable role in the field of construction machinery, so more and more simulation software has been specifically applied to cycloid gear tooth profiles The simulation of the motion curve, but the characteristic parameters involved in the simulation of the existing cycloid tooth profile motion curve are relatively simple, which makes the simulation result have a large error and will bring damage to the actual application of the reducer
