A Method of Accurately Obtaining the Reduction Ratio of the Reducer

Abstract

The invention discloses a method for precisely calculating a reduction ratio of a reducer. The method comprises the following steps: determining a pulse number necessary for a servo motor of an input shaft of the reducer to run for a circle by a servo controller of the equipment, then, driving the servo motor to rotate for a circle by the equipment and obtaining data of an output shaft of the reducer, using a cyclic derivation method to calculate a cycle number when a condition is satisfied according to the obtained data, and finally, calculating the reduction ratio of the reducer by the obtained cycle number. By adopting the method disclosed by the invention, on the premise that the equipment is not dismounted, the reduction ratio of the reducer can be obtained quickly and precisely by a mathematic tool by detecting several parameters of the equipment.

Description

technical field [0001] The invention relates to the field of industrial control, in particular to a method for solving the reduction ratio of a reducer. Background technique [0002] In the industrial field, reducers are widely used in various numerical control equipment and industrial robots. In industrial robots, the input shaft of the reducer is driven by a servo motor to provide precise position input, and the output shaft of the reducer is connected to the collet or robot joint parts. [0003] For manufacturers, they generally only provide the output value at the end of the industrial robot, and do not give the proportional relationship between the motor pulse and the output value at the end. This proportional relationship is also the reduction ratio of the reducer. When you need to use this parameter, you will encounter the following problems: ① It is inconvenient for the manufacturer to provide the model of the reducer or the reduction ratio value in the equipment; ②...

Problems solved by technology

When you need to use this parameter, you will encounter the following problems: ① It is inconvenient for the manufacturer to provide the model of the reducer or the reduction ratio value in the equipment; ② It is inconvenient to obtain the model of the reducer by disassembling the CNC equipment or industrial robot ;③If the numerical control equipment or industrial robot end position change value is directly divided by the number of pulses passed by the motor to solve the deceleration ratio, the precise deceleration ratio cannot be obtained because the numerical control equipment or industrial robot only displays a limited number of output values

[0004] That is to say, in actual engineering applications, when engineers use CNC equipment or industrial robots for kinematics simulation purposes, they often cannot quickly and accurately know the reduction ratio of the reducer in CNC equipment or industrial robots.
