A Modeling Method for Encoder Knob Track Data

Abstract

The invention provides a data modeling method of encoder knob track, which includes obtaining the torque curve of the encoder knob track; determining the structural parameters according to the design requirements of torque or load, and constructing the climbing torque formula and formula through the relationship between geometry and force Downhill torque formula, and further divide the torque curve into a plurality of sequentially connected climbing straight lines and / or downhill straight lines, and the slope of each climbing straight line and downhill straight line can be transformed by polar coordinates to form a track The corresponding relationship between the radius and the angle increment; determine the starting point and its corresponding return angle, correction angle and track radius, and calculate each climb in sequence by using the climbing and downhill torque formula according to the preset angle increment. The orbital radius of the slope straight line and / or the downhill straight line; the orbital radius calculated in sequence is fitted to draw the target orbital curve. The invention is implemented to solve the problem of low efficiency of encoder knob track modeling in the prior art.

Description

technical field [0001] The invention relates to the technical field of machinery industry, in particular to an encoder knob track data modeling method. Background technique [0002] During the design process, mechanical parts need to be solidly modeled for strength analysis and structural optimization design. In addition, they can also be used for assembly analysis and CNC machining. [0003] In the prior art, the design of the encoder knob track has the following disadvantages: (1) The design curve of the tooth shape is too simplified, and the determined value of the spring is only the maximum compression load (stiffness and preload are uncertain), which cannot guarantee the torque change during the process, It is difficult to design complex torque (for example, the maximum torque value is not at the maximum compression position and the position is required), and it is impossible to control the torque growth slope to ensure the return position; (2) The maximum torque value ...
