Noise testing device for speed reducer

Abstract

The invention discloses a noise testing device for a speed reducer. The device comprises a bottom plate, a connecting unit, a lifting unit, a lifting plate and a double-shaft motor, two symmetrically-distributed guide rails are arranged on the left side of the upper surface of the bottom plate. Rack grooves are formed in the inner sides of the guide rails; four supporting legs which are symmetrically distributed are arranged at the right end of the upper surface of the bottom plate; the upper surfaces of the support legs are connected with the lower surface of a bedplate; the upper surface ofthe bedplate is fixedly connected with the lower surface of a stator of the linear motor; the upper surface of a rotor of the linear motor is fixedly connected with a test motor; the connecting unit is arranged at the tail end of the output shaft of the test motor; the end head of the output shaft of a dual shaft motor is fixedly connected with the gear, the gear is connected with the inside of the corresponding rack groove in an engagement way, and a movable plate is fixedly connected on the upper surface of the dual shaft motor. According to the noise testing device for the speed reducer, anassembly line operation mode is adopted, the noise testing device for the speed reducer is high in testing speed, high in efficiency and accurate in testing result, manpower and labor force are saved, and convenience is brought to people.

Description

technical field [0001] The invention relates to the technical field of reducer assembly, in particular to a reducer noise testing device. Background technique [0002] The reducer is the intermediate link in which the power unit drives the actuator. It converts high-speed and low-torque into low-speed and high-torque. It is used in conjunction with the engine. During operation, the reducer will produce a certain amount of noise. If the noise exceeds a certain range, it means that the reducer is faulty. Problem, therefore, after the reducer is assembled, it is necessary to perform noise detection on it. In the prior art: the patent of authorized publication number CN207937158U discloses a reducer noise test platform, which includes a base platform fixed horizontally on the base platform The positioning table of the reducer, the guide column vertically fixed on the rear side of the abutment, the motor mounting plate slidably installed on the guide column, the motor fixed on th...

[0002] The reducer is the intermediate link in which the power unit drives the actuator. It converts high-speed and low-torque into low-speed and high-torque. It is used in conjunction with the engine. During operation, the reducer will produce a certain amount of noise. If the noise exceeds a certain range, it means that the reducer is faulty. Problem, therefore, after the reducer is assembled, it is necessary to perform noise detection on it. In the prior art: the patent of authorized publication number CN207937158U discloses a reducer noise test platform, which includes a base platform fixed horizontally on the base platform The positioning table of the reducer, the guide column vertically fixed on the rear side of the abutment, the motor mounting plate slidably installed on the guide column, the motor fixed on the motor mounting plate, and the wire that drives the motor mounting plate to slide up and down along the guide column The rod nut assembly needs to be manually tested one by one reducer, the test speed is slow, the efficiency is low, the test requires a lot of people, a waste of manpower and labor, and the test result is inaccurate, so we propose a reducer noise test device address the above deficiencies
