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
The present invention relates to a kind of section's dress method of engine transmission case lid, relate in particular to a kind of section's dress method of pedal motorcycle engine transmission-case cover.
Background technique
As illustrated in fig. 1 and 2, at present, section's dress method of engine transmission case lid is: first transmission-case cover 4 is placed on supporting base 7, adopt pressure head respectively main shaft bearing 1, mistake wheel bearing 5, driving shaft bearing 6 to be press fit on the relevant position of transmission-case cover 4, then main shaft 2 is pressed into to the endoporus of main shaft bearing 1 by pressure head 8, press the transmission-case cover after rear upset section dress, be pressed into main shaft oil sealing 3.
While adopting the method section dress transmission-case cover, the length be pressed in the hole of main shaft bearing 1 due to main shaft 2 is longer, if main shaft 2 be placed with inclination slightly, main shaft 2 to be pressed into the centering process very long; In addition, main shaft 2 is pressed in the centering process and produces lateral pressure, and pressure is delivered on transmission-case cover 4 by main shaft bearing 1, causes the main shaft bearing hole of transmission-case cover 4 to be out of shape because of stressed, and then the circular runout that main shaft 2 is press fit into after transmission-case cover 4 becomes large.During the motor operation, can affect because of circular runout the transmission of power, thereby affect the happy property that car load is ridden.
Summary of the invention
In prior art, in engine transmission case cap process of assembling, the main shaft bearing hole stress deformation that main shaft causes transmission-case cover is installed, and then the circular runout that main shaft is press fit into after transmission-case cover becomes large technical problem, the purpose of this invention is to provide a kind of engine transmission case cap dress method, the method completes section's dress of main shaft and main shaft bearing by bearing support block, then the main shaft after section dress and transmission case cap are filled, solved the technical problem that main shaft is press fit into the main shaft bearing hole stress deformation after transmission-case cover.
To achieve these goals, the present invention has adopted following technological scheme:
A kind of transmission case cap dress method comprises the following steps:
The main shaft bearing that step 3. has filled main shaft by pressure head by section is press fit into the relevant position of transmission-case cover;
The transmission-case cover upset that step 4. has filled section main shaft bearing, crossed wheel bearing and driving shaft bearing, be pressed into the main shaft oil sealing, completes section's dress of transmission-case cover.
Preferably, in step 3, adopt long pressure head while press-fiting main shaft bearing.
Preferably, in step 1 and step 2, adopt common short pressure head to press-fit.
Useful technique effect of the present invention is:
Transmission case cap dress method of the present invention, first by bearing support block, complete section's dress of main shaft and main shaft bearing, then the main shaft after section's dress is pressed into to transmission-case cover, solved first section dress main shaft bearing, again main shaft is pressed in the process of transmission-case cover, because main shaft tilts to cause the technical problem of centering difficulty; Avoid causing in main shaft centering process the technical problem of transmission-case cover main shaft bearing bore deformation simultaneously, guaranteed section's packing quality of transmission-case cover, reduced the circular runout after main shaft is press fit into transmission-case cover, guaranteed the flat smooth property of engine power output.

Embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described in further details.
As shown in Figure 1, section's mounted engine transmission-case cover, need to be arranged on main shaft bearing 1, main shaft 2, main shaft oil sealing 3, mistake wheel bearing 5 and driving shaft bearing 6 relevant position of transmission-case cover 4.
As shown in Figures 3 and 4, engine transmission case cap dress method of the present invention comprises the following steps:
The main shaft bearing 1 that step 3. has filled main shaft 2 by pressure head 10 by section is press fit into the relevant position of transmission-case cover 4; In this step, pressure head adopts long pressure head 10, long pressure head 10 can be fixing by the section of press-fiting of main shaft 2, in the process press-fited, main shaft 2 is difficult for producing, guaranteed to press-fit quality, avoided the centering operation after main shaft tilts, the lateral pressure that while also having avoided centering, main shaft produces causes the main shaft bearing bore deformation of transmission-case cover.
Transmission-case cover 4 upsets that step 4. has filled section main shaft bearing 1, crossed wheel bearing 5 and driving shaft bearing 6, be pressed into main shaft oil sealing 3, completes section's dress of transmission-case cover.
Finally explanation is, above embodiment is only unrestricted in order to technological scheme of the present invention to be described, although with reference to preferred embodiment, the present invention is had been described in detail, those of ordinary skill in the art is to be understood that, can modify or be equal to replacement technological scheme of the present invention, and not breaking away from aim and the scope of technical solution of the present invention, it all should be encompassed in the middle of claim scope of the present invention.
