Abstract

The invention discloses an engineering machinery gearbox rack durability test connection device and relates to the technical field of engineering machinery. The connection device comprises a flange seat with a through hole. An input flange is arranged on the upper portion of the flange seat, an inner cavity used for sleeving a gearbox input shaft is arranged in the input flange, and a flange connection portion connected with the motor output shaft portion is arranged at the front end. A cover plate connected with the casing is arranged on the shoulder of the flange seat. Compared with the prior art, the device ensures that the input end and the output end of the gearbox are in rigid connection, gearbox durability test is conducted under intensified load, and the durability test time can be effectively reduced.

Description

technical field [0001] The invention relates to the technical field of engineering machinery, in particular to a connection device for durability test of an engineering machinery transmission bench. Background technique [0002] In the process of R&D and design of construction machinery gearboxes, bench test verification is an indispensable and important link in the research and development process. The bench test verification includes dry running test, load characteristic test, etc.; during the test, the motor needs to be placed on the test bench It is connected with the gearbox, and for the durability test of the gearbox of construction machinery, the design service life of the gearbox is generally required to be ≥10000h, and the test time requirement is generally correspondingly longer. The existing bench durability test installation methods are as follows: figure 1 As shown, the guide wheel seat 11 is installed on the housing 7, on which there is a torque converter core...
