Problems solved by technology

[0004] Aiming at the technical problem in the prior art that during the installation of the engine transmission case cover, the installation of the main shaft causes the main shaft bearing hole of the transmission case cover to be deformed by force, which further increases the radial runout of the main shaft after it is press-fitted to the transmission case cover. The purpose of the invention is to provide a method for installing the cover of the engine transmission case. This method completes the partial assembly of the main shaft and the main shaft bearing through the bearing support seat, and then installs the partially assembled main shaft and the cover of the transmission case to solve the problem of pressing the main shaft to the The technical problem of the deformation of the main shaft bearing hole behind the transmission case cover

Embodiment Construction

[0024] The specific implementation manner of the present invention will be described in further detail below in conjunction with the accompanying drawings.

[0025] Such as figure 1 As shown, to partially install the engine transmission case cover, it is necessary to install the main shaft bearing 1, the main shaft 2, the main shaft oil seal 3, the wheel shaft bearing 5 and the drive shaft bearing 6 on the corresponding positions of the transmission case cover 4.

[0026] Such as image 3 and 4 Shown, the engine transmission box cover part adornment method of the present invention may further comprise the steps:

[0027] Step 1. Place the main shaft bearing 1 on the bearing support seat 9, then put the main shaft 2 into the inner hole of the main shaft bearing 1, press the main shaft 2 into the hole of the main shaft bearing 1 through the pressure head, and complete the main shaft bearing 1 and the main shaft 2; in this step, the indenter adopts the short indenter 8, which ...

Abstract

The invention discloses a fitting method of a transmission case cover. The method includes: fitting a spindle and spindle bearings through bearing supports and pressing the fitted spindle to a transmission case cover body to allow the spindle bearings to be fitted first. The problem that inclination of the spindle causes difficulty in alignment during the process of the spindle pressed to the transmission case cover body is solved; the technical problem that spindle bearing holes of the transmission case cover body deform during the alignment process of the spindle is also avoided; fitting quality of the transmission case cover is guaranteed; after pressed to the transmission case cover body, the spindle rarely jumps radially, and power output smoothness of an engine is guaranteed.

Description

technical field [0001] The invention relates to a partial installation method of an engine transmission case cover, in particular to a partial installation method of a scooter engine transmission case cover. Background technique [0002] Such as figure 1 and 2 As shown, at present, the partial installation method of the engine transmission case cover is as follows: first place the transmission case cover 4 on the support seat 7, and press the main shaft bearing 1, the passing wheel shaft bearing 5, and the drive shaft bearing 6 to the transmission case respectively by using a pressure head. On the corresponding position of the box cover 4, then press the main shaft 2 into the inner hole of the main shaft bearing 1 through the pressure head 8, after pressing, turn over the installed transmission case cover, and press the main shaft oil seal 3. [0003] When using this method to install the cover of the transmission box, since the length of the main shaft 2 to be pressed int...
