Press-fitting mechanism, method and error-proof method thereof for tapered roller bearing

Abstract

The invention discloses a press-fitting mechanism for a tapered roller bearing. The press-fitting mechanism comprises a fixing frame. The top and bottom of the fixing frame are correspondingly provided with a stamping part and a press-fitting part matching press-fitting. The stamping part, an intermediate shaft to be press-fitting and the press-fitting part are coaxially connected together in a abutting mode at the moment of press-fitting, wherein the pressing part includes a driving part, a stamping fixture and a centering cone sequentially connected; the two sides of the driving part are correspondingly connected with two guiding shafts; the two guiding shafts are slidably arranged on the fixing frame in a mirror-symmetric mode; the stamping fixture, the centering cone and the guiding shafts move up and down with the driving part relative to the press-fitting part; and the press-fitting part comprises a guiding fixture, and the guiding fixture is arranged at the bottom of the fixingframe. Compared with the prior art, according to the actual situation of the intermediate shaft to be press-fitting, the intermediate shaft can complete the press-fitting of large and small tapered roller bearings at a time through pressing downward of the stamping part; and through the cooperation of the stamping part and the press-fitting part, the large and small tapered roller bearings can beinstalled stably and correctly on the intermediate shaft at the same time.

Description

technical field [0001] The invention relates to a press-fitting tool, which belongs to the field of automobile manufacturing, in particular to a tapered roller bearing press-fitting mechanism. Background technique [0002] The 6AT transmission is composed of more than 200 parts, large and small, mainly consisting of housing components, torque converter housing components, oil pump assembly, intermediate support assembly, C1 clutch and rear planetary carrier assembly, C2 / C3 Clutch and front planetary carrier assembly, hydraulic torque converter, valve body assembly, differential and planetary carrier assembly, intermediate shaft, intermediate support shaft gear and other parts, among which the role of shaft gear in the transmission is not necessary Undoubtedly, the shaft and gear parts are all rolling parts, and it is a big problem to press the bearing on the shaft and gear parts; in the practical application of 6AT gearbox, the shaft and gear parts occupy the core position, ...

AI Technical Summary

Problems solved by technology

[0003] The tapered roller bearing and the intermediate shaft belong to an interference fit. In the face of the demand for large production, ordinary mechanisms cannot meet the requirements.
