Abstract

The invention discloses a gear vibration testing device. The device comprises a motor, an output shaft of the motor is sequentially connected with a first gear box and/or a second gear box and a loadmechanism, the motor is further connected with a frequency converter, the first gear box is a straight/oblique gear box, the second gear box is a planetary gear box, and gears in the first gear box and the second gear box are respectively provided with sensors. Principal experiments of a transmission ratio, abrasion, a clearance, a temperature, pollution, lubrication and the like on gear influences in the gear transmission process can be carried out.

Description

technical field [0001] The invention belongs to the technical field of testing equipment, and relates to a gear vibration testing device. Background technique [0002] In Modern Machine Learning Work Trial Practice. Predictive maintenance (pdm) based on mechanical working status and diagnostic technology is a very reliable cost-saving method, through which scientific and reasonable maintenance strategies can be formulated, so that mechanical failures can be detected and repaired before irreversible damage. The existing testing equipment for the influencing factors in the mechanical transmission process cannot quickly and accurately obtain the vibration signal of the gear. Contents of the invention [0003] The purpose of the present invention is to provide a gear vibration testing device, which solves the problem in the prior art that the vibration signal of the gear cannot be obtained quickly and accurately. [0004] The technical solution adopted in the present inventi...
