Abstract

The invention discloses a method for detecting the sealing performance of a shell junction surface, and the method comprises the following steps: 1), building a three-dimensional digital model of a CAD of a gearbox shell, and importing the three-dimensional digital model into finite element software; 2) simplifying a gearbox shell model; 3) carrying out degree-of-freedom constraint on the simplified shell model, and loading bolt pre-tightening force; (4) performing working condition loading on the constrained shell model, and (5) setting solving parameters to obtain the deformation cloud picture, and comparing deformation parameters of the deformation cloud picture with a design target value to obtain sealing performance parameter. The detection method is completed in software, calculationresults are visual, high in precision and low in cost, and the result is not influenced by the external environment.

Description

technical field [0001] The invention relates to the judgment of the tightness of a gearbox casing, in particular to a method for detecting the tightness of a joint surface of a casing. Background technique [0002] The casing is an important component of the transmission structure, which plays a role in supporting, protecting the internal gear transmission mechanism and preserving lubricating oil. The joint surface of the transmission case mainly refers to the bolt connection joint between the front and rear cases, between the case and the bearing cover, and between the case and the oil pan, and its sealing performance is more critical to the performance of the transmission. Poor sealing, on the one hand, is likely to cause lubricating oil leakage and pollute the environment; on the other hand, a large amount of lubricating oil leakage is likely to cause poor gear lubrication, gear ablation, and affect transmission efficiency and assembly reliability. [0003] The tradition...
