On the ball.
Preferably, the end of the stop bit bolt is equipped with an arc groove, and the ball is located in arc groove.
Preferably, the stop block is in cylindrical shape.
The beneficial effects of the utility model are：
It is the design its novel in structural design, compact, the axial movement of line shaft can be limited by the design of stop block, together
When, the use of ball can avoid stop block and contact generation the problem of influencing shell internal gear group that causes to be worn with line shaft, then
Person, the design is by removably designing convenient for safeguarding, replacement associated components.
Detailed description of the invention
Fig. 1 is the profile status structural schematic diagram of the utility model；
Fig. 2 is the portion A enlarged structure schematic diagram in Fig. 1.
Specific embodiment
The present invention will be further described with reference to the accompanying drawings and examples：
Embodiment 1：A kind of hub reduction gear, referring to Fig. 1, Fig. 2.
It includes shell, the reducing gear group being correspondingly arranged in shell；For one with driving axis connection in reducing gear group
Grade sun gear 3 is located at the intracorporal center position of shell, and the shell includes left housing 1 and right shell 2（The above are the prior arts）.
It is left that the design is equipped with protrusion in the left housing 1 that the center position with 3 end of level-one sun gear is oppositely arranged
The stop block 4 of 1 inner wall of shell, the stop block are in cylindrical shape, and the stop block 4 is flexibly connected with the left housing 1, specifically,
The left housing 1 is equipped with circular hole, and it further includes one and the matched plectane of the bore inner diameter that the end of circular hole, which is equipped with step cutting pattern,
11, the stop block is set to the center position of plectane 11, and plectane 11 is integrally formed with stop block, and the plectane 11 is located at
On step cutting pattern in circular hole, and the edge of the plectane 11 is connect by fixing bolt 12 with the step cutting pattern, is so set
The achievable stop block of meter is flexibly connected with left housing, and when left side is mobile in power axial view, line shaft can be against stop block
On, the axial movement of line shaft can be so limited by stop block.
Embodiment 2, place same as Example 1 repeat no more, the difference is that：The design is also in the plectane 11
Center position is equipped at least one through-hole 5, and the through-hole 5 runs through plectane and stop block 4, and 5 internal screw thread of through-hole is connected with stop bit
Bolt 9, the length of the stop bit bolt 9 is greater than the depth of through-hole, and the front end of stop bit bolt 9 extends to the outside of stop block 4
And for being contacted with the end of line shaft to limit line shaft and move to the left, stop bit is adjusted by the design of stop bit bolt 9
Spacing between 9 end of bolt and line shaft, meanwhile, lead to stop bit after the end of stop bit bolt 9 is contacted with line shaft end
Bolt 9 only needs to change stop bit bolt 9 after being worn.
Embodiment 3, referring to fig. 2, place same as Example 1 repeat no more, the difference is that：In the plectane 11
At least one through-hole 5 is equipped at heart position, plectane and stop block 4 are run through in logical 5 holes, positioned at the through-hole end of 1 inside of left housing
