Transfer case

Abstract

The invention provides a transfer case. The transfer case comprises an upper case body formed by welding and a lower case body formed by welding. The upper case body is in threaded connection with the lower case body, and at least two pairs of bearing holes are formed in the lower case body and used for an input shaft and an output shaft to penetrate in. By means of the transfer case, the problem of poor matching between a bearing and the bearing holes of an existing transfer case is solved, and therefore, the service life of the transfer case is prolonged.

Description

technical field [0001] The invention relates to mechanical transmission equipment technology, in particular to a transfer case. Background technique [0002] The transfer case is a device that can redistribute the power output by the engine to drive other equipment. For example, in the field of construction machinery, the power output by the diesel engine can also drive hydraulic pumps, generators, etc. after the speed is adjusted by the transfer case to drive the construction machinery equipment to drive and operate. [0003] At present, the transfer case body is mostly made of casting technology. figure 1 It is a structural schematic diagram of a transfer case in the prior art, such as figure 1 As shown, the transfer case includes two parts, the upper case body 1 and the lower case body 2, which are respectively cast. The upper case body 1 and the lower case body 2 are respectively provided with semicircular gaps, and the upper case body 1 and the lower case body 2 pass ...
