Abstract

The invention belongs to the technical field of test and evaluation of gear box reliability, specifically relates to a method of static bending test of gear box assembly and a special test device. The invention fills the blank in the rigidity test and evaluation of the gear box assembly. The method for static bending test of gear box assembly comprises the following steps: 1) clamping the gear box, applying pressures on the upper and bottom surfaces, starting, recording data; 2) dividing 8 equal parts of the gear box assembly, measuring; and 3) comparing the measured data. The special test device comprises a frame, a rotator clamping system, a gear box calibrating system, and a system for applying pressures on the supper and bottom of an output flange of the gear box to be test. The invention fills the blank in the related test of the gear box, provides the data support for the measurement and evaluation of reliability of gear box assembly, efficiently shorts the development cycle of the gear box assembly, realizes the quality control of batch products, and reduces the development costs of new products. The invention has improved social and economic benefits.

Description

technical field [0001] The invention belongs to the technical field of transmission reliability test evaluation methods and equipment, and specifically relates to a transmission assembly static bending test method and its special test equipment, which is suitable for the development of new products and mass-produced products of transmissions in automobiles, engineering machinery, and agricultural machinery engineering Quality supervision and evaluation. Background technique [0002] The transmission assembly is an important part of automobiles, construction machinery, and agricultural machinery.
