Abstract

The invention discloses a mechanical transmission closed test bed and a test method thereof. The test bed comprises a motor, connection gear boxes, a torque and rotation speed sensor, a tested transmission, an accompanying transmission and a loader, wherein the loader comprises a spiral spline shaft, a loaded gear, a plane bearing, a pair of wedge cushion blocks, a sliding bearing, a thrust bar and an oil cylinder; the motor is connected with the left connection gear box for providing rotation power for the overall closed test bed; the two transmissions are connected in a back-to-back mode, the tested transmission is connected with the left connection gear box via the torque and rotation speed sensor and the accompanying transmission is directly connected with the right connection gear box; and the loader is arranged onto the right connection gear box for providing different loads for the overall closed test bed. A transmission fatigue life test and a reliability test can be carried out, the closed structure is adopted, the cost is low, energy is saved, the structure is compact, the use is convenient, and the test bed can be applied to transmissions of various models.

Description

technical field [0001] The invention belongs to the technical field of mechanical transmissions, and in particular relates to a closed test bench for mechanical transmissions and a testing method thereof. Background technique [0002] With the rapid development of the economy, more and more people buy family cars. In the auto market, the basic performance of each component of the car is an important indicator for evaluating the car. The durability and service life of the transmission are one of the most important. item. There are two types of transmission test benches: open type and closed type. The mechanical closed type test bench is a test device used to test the performance of transmissions in the machinery industry, especially in the automotive industry. It is mainly used to determine the durability and service life of the transmission. , Transmission efficiency and the influence of various factors, such as design factors, manufacturing process, materials, load, speed,...
