RV reducer delivery quality comprehensive performance quantitative detection experiment table and detection method thereof

Abstract

The invention discloses an RV reducer delivery quality comprehensive performance quantitative detection experiment table and a detection method thereof. The RV reducer delivery quality comprehensive performance quantitative detection experiment table comprises an eccentric sleeve arranged on a first sensor shaft, the eccentric sleeve is sleeved with a sensor outer cylinder, and the eccentric sleeve rotates along with the first sensor shaft and a second sensor shaft; displacement signals between the laser displacement sensor and the eccentric sleeve are obtained in real time through the high-precision laser displacement sensor, a characteristic signal curve is obtained through a data acquisition card and a LabVIEW design data acquisition system, and the transmission ratio of an input shaft to an output shaft of the RV reducer is calculated after frequency spectrum transformation. The transmission error of the RV speed reducer can be obtained by comparing the theoretical transmission ratio with the actual transmission ratio, non-contact measurement is achieved through combination of the high-precision laser displacement sensor and the eccentric sleeve, and characteristic signals of the RV speed reducer can be accurately captured and identified.

AI Technical Summary

Problems solved by technology

[0003] However, to achieve quantitative detection of RV reducer performance, the first problem is to have efficient signal extraction and signal processing methods, as well as high-resolution and high-precision sensors to accurately capture and identify its characteristic signals

The traditional feature signal extraction means mainly rely on the vibration acceleration sensor to obtain the vibration signal, or the encoder to obtain the instantaneous speed signal, but the structure of the RV reducer is complex, and it is mostly used in low-speed and heavy-duty working conditions, and the motion form is reciprocating motion. The vibration acceleration sensor and encoder have certain limitations in extracting the characteristic signal of the RV reducer. The vibration acceleration sensor is not suitable for low-speed working conditions, and the encoder is not suitable for reciprocating motion and can only be installed on the shaft end
