A cycloidal tooth profile curve simulation method and system for a reducer

Abstract

The invention provides a method for simulating the cycloidal tooth profile curve of a reducer, which includes obtaining the relevant motion data of the cycloidal gear teeth of the reducer, and drawing the actual curve of the cycloidal tooth profile motion; according to the geometric structure of the reducer, the The theoretical equation of the linear tooth profile curve and its specification parameters, as well as the calculation formula for determining the correction parameters and simulation parameters; determine the current correction parameter value, and after extracting the value of the specification parameter from the relevant motion data, calculate the specific value of the simulation parameter , to further simulate the theoretical curve of the cycloidal gear profile movement; compare the actual curve and the theoretical curve to see if there is a distance difference greater than the preset threshold; if yes, modify the current correction parameter value and continue the simulation; otherwise, output the final simulation theoretical curve. By implementing the present invention, combining the reality and theory of the cycloid gear teeth of the reducer, a plurality of characteristic parameters are formed for simulation to reduce the simulation error and improve the reliability, accuracy and high efficiency of the data.

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
