The existing half shaft gear is in a wear environment for a long time, the problem of loss of the half shaft gear still exists in the past, particularly, for an internal gear in the half shaft gear, the loss is larger, the problem that operation is not sensitive enough in the use process of an automobile in the later period is caused, potential safety hazards are caused, but the whole half shaft gear is required to be replaced in the maintenance of the automobile, and therefore the transmission half shaft gear forging is provided for solving the problem.

SUMMERY OF THE UTILITY MODEL

The utility model provides a pair of gearbox half shaft gear forging has solved the easy loss of gear that the half shaft gear that uses at present exists and has leaded to changing inconvenient problem.

In order to achieve the above purpose, the utility model adopts the following technical scheme:

the utility model provides a gearbox half shaft gear forging, includes the leading pulley shell, the leading pulley shell surface is evenly distributed fixed mounting along the outer wall profile has the tooth, the lower surface central point of leading pulley shell puts fixed mounting has the leading shaft pipe, the internal gear section of thick bamboo has been placed to the leading shaft inside, the inner wall of internal gear section of thick bamboo is evenly distributed along the inner wall profile and has seted up the internal tooth, all be evenly distributed on leading shaft pipe and the internal gear section of thick bamboo and set up the installation screw hole of matcing, the inside hexagon socket head cap screw of having placed of installation screw hole, all seted up the mounting hole on leading shaft pipe and the internal gear section of thick bamboo, and be evenly distributed on leading shaft pipe and the internal gear section of thick bamboo and seted.

Preferably, the hexagon socket head cap screw is provided with a thread, and the inner wall of each fixed screw hole is provided with a thread groove matched with the thread.

Preferably, the fixing screw hole on the inner gear cylinder is located inside the inner gear cylinder and does not penetrate through the inner gear cylinder.

Preferably, a chamfer angle of C2 is formed at the bottom of the main shaft tube.

Preferably, the main guide wheel shell is in an inverted circular truncated cone shape, and spherical placing grooves are uniformly distributed on the lower surface of the main guide wheel shell.

The utility model has the advantages that: 1. in the half axle gear forging, high-strength and wear-resistant teeth are adopted, the inverted-truncated-cone-shaped main guide wheel shells are combined with each other, two half axle gears of the same type or different types are installed in a matching mode according to production requirements, a multistage transmission mode in the internal transmission relation of an automobile can be realized, and the wear degree of the teeth can be reduced through the high-strength teeth when an automobile engine is used for a long time, so that the service life of the half axle gear is prolonged. 2. In this side gear forging, the half shaft pipe that uses is independent to come out the inside used internal gear to cooperate the installation through hexagon socket head cap screw, because the internal gear wearing and tearing loss is great, the later stage that leads to uses not agilely, after a side gear damaged to some extent, only need to dismantle the internal gear section of thick bamboo, and the internal gear section of thick bamboo of more renewing, just can reuse, needn't change whole side gear again, the input fund of saving user in later stage maintenance and maintenance that can be great.

To sum up, this side gear forging has better service condition, increases life, the installation and the dismantlement in the later stage maintenance of being convenient for simultaneously, and the practicality is high.
