Electric locomotive speed reducer assembly noise testing device and testing method thereof

Abstract

The invention relates to an electric locomotive speed reducer assembly noise testing device and a testing method thereof. The electric locomotive speed reducer assembly noise testing device comprisesa rack, a speed reducer connecting mechanism, a half-shaft axle housing connecting mechanism and a load mechanism are connected with the rack, and the speed reducer connecting mechanism comprises a transmission mechanism which comprises a rotating base and a motor connecting flange base; the speed reducer assembly is pressed on the rotating base through a first driving air cylinder, the motor connecting flange base is connected with a driving motor in driving connection with the speed reducer assembly, the half-shaft axle housing connecting mechanism comprises an axle housing body, an upper axle housing body connecting oil filling port, a lower axle housing body connecting oil filling port and an oil drain valve, two half shafts penetrate through the two sides of the axle housing body, andthe axle housing body is further connected with a second driving air cylinder. The load mechanism comprises a sliding shaft, the two ends of the sliding shaft are connected with a rotating shaft anda third driving air cylinder respectively, the rotating shaft is connected with a disc brake disc, and the sliding shaft matching the disc brake disc is connected with disc brake pincers. The electriclocomotive speed reducer assembly noise testing device and the testing method thereof are used for testing noise generated when the speed reducer assembly runs, and testing installation and operationare simple.

Description

technical field [0001] The invention relates to a noise test of a reducer assembly, in particular to a noise test device and a test method for an electric locomotive reducer assembly. Background technique [0002] The electric vehicle reducer is an important part for connecting the drive end motor and the drive half shaft. When the reducer is working, the gears in the reducer rub against each other, which will generate noise. The load and sliding noise, the traditional test needs to be tested on the car, the test installation is troublesome, and the operation is troublesome. Contents of the invention [0003] In view of the above shortcomings, the applicant has made researches and improvements, and provides a noise testing device and testing method for an electric locomotive reducer assembly. [0004] The technical scheme adopted in the present invention is as follows: [0005] A noise test device for an electric locomotive reducer assembly, comprising a frame on which a...
