Description
Technical field
The utility model belongs to planetary reduction gear field, in particular to a kind of planet pin mounting structure.
Background technique
Currently, driving axle of forklift can be divided into dry type braking bridge and wet braking bridge by the difference of mode of braking.Dry type braking
Bridge mostly uses drum brake, and drum brake configuration is simple, and cost is relatively low；Compared to dry type braking bridge, its braking of wet braking bridge
Performance is more stable, and braking ability is preferable, and the service life is longer for brake.Hub reduction gear is a kind of speed reducer in drive axle
Structure, deceleration mechanism mostly use planetary gear train to slow down.The fixation of planet pin is expert at frequently with resilient key in planet hub reduction gear
Mounting hole is radially opened up on star pin and planet carrier, by installing resilient key by planet finger setting on planet carrier, this limit
Position mechanism leads to the installation of planetary gear train and opens and inspect relatively complicated.
Utility model content
The purpose of this utility model is to provide a kind of planet pin mounting structures, it is ensured that planet pin and planet carrier cooperation are pacified
Dress, stable structure and easy to disassemble.
To achieve the goals above, the utility model takes following technical scheme: a kind of planet pin mounting structure, including row
Star pin, the border that the planet pin closes on upper surface are provided with convex block, and planet carrier, which is offered, to coincide with the shaft of planet pin
Through-hole, the peripheral wall of through-hole offer the groove that inlay card cooperation is constituted with convex block, and the one side wall of groove is open-like shape and planet carrier
Upper surface is concordant, and the upper surface of planet pin is provided with the cover board connecting with the upper surface of planet carrier.
The border that the planet pin closes on upper surface offers dome-type recess portion, and dome-type recess portion insertion steel ball forms convex
Block, the groove include coincideing from the upper surface of planet carrier to the semi-cylindrical groove of the interior arrangement that postpones and with dome-type recess portion
A quarter ball slot.
The dome-type recess portion uniform intervals are disposed with same circular section that is multiple and being in planet pin, groove corresponding half
Also uniform intervals arrangement is multiple for ball-type recess portion.
It is clearance fit between the steel ball and dome-type recess portion, a quarter ball slot.
The upper surface of the planet carrier offers mounting hole, and cover board is made up of bolt and mounting hole and connects.
In above-mentioned technical proposal, the border of the upper end of planet pin is provided with convex block, and planet pin is postponed through-hole merging, then convex
Block and the groove of through-hole peripheral wall setting carry out inlay card and form positioning, and at this moment planet pin is concordant with the upper surface of planet carrier, using lid
Plate is attached fixation, completes being coupled for planet pin and planet carrier, drives planet carrier to be rotated when planet pin rotates, adopt
It is installed with the inlay card mode of convex block and groove simple and easy to disassemble.
Detailed description of the invention
Fig. 1 is the utility model partly cut-away schematic diagram；
Fig. 2 is that planet pin and planet carrier cooperate cross-sectional view；
Fig. 3 is planet carrier partial sectional view.
Specific embodiment
It is made further instructions in conjunction with Fig. 1 ~ 3 pair the utility model:
A kind of planet pin mounting structure, including planet pin 1, the border that the planet pin 1 closes on upper surface are provided with convex
Block, planet carrier 2 offer the through-hole 3 coincideing with the shaft of planet pin 1, and the peripheral wall of through-hole 3 is offered matches with convex block composition inlay card
The groove 4 of conjunction, the one side wall of groove 4 are that open-like shape is concordant with the upper surface of planet carrier 2, the upper surface of planet pin 1 be provided with and
The cover board 5 of the upper surface connection of planet carrier 2.The border of the upper end of planet pin 1 is provided with convex block, and the through-hole 3 of postponing of planet pin 1 is set
Enter, the groove 4 of subsequent convex block and the setting of 3 peripheral wall of through-hole carries out inlay card and forms positioning, at this moment the upper end of planet pin 1 and planet carrier 2
Face is concordant, is attached fixation using cover board 5, completion planet pin 1 is coupled with planet carrier 2, and planet pin 1 drives when rotating
Planet carrier 2 is rotated, and is installed using the inlay card mode of convex block and groove 4 simple and easy to disassemble.
The border that the planet pin 1 closes on upper surface offers dome-type recess portion 6, and dome-type recess portion 6 is embedded in 7 shape of steel ball
At convex block, the groove 4 includes recessed from the upper surface of planet carrier 2 to the semi-cylindrical groove 41 of the interior arrangement that postpones and with dome-type
The identical a quarter ball slot 42 in portion 6.Merely during rotation using the inlay card mode of convex block and groove 3, convex block can be held
It by biggish torsion, is easy to happen abrasion and is easy to happen fracture, first by 7 inlay card of steel ball to dome-type recess portion 6, then be directed at half
Cylinder type groove 41, which postpones steel ball 7, slides into a quarter ball slot 42, completes the limit of steel ball 7, then consolidated using cover board 5
Even, when planet pin 1, which works, to be rotated, it is circumferential that steel ball 7 can carry out low-angle in dome-type recess portion 6 and a quarter ball slot 42
Rotation, while also will drive planet carrier 2 and being rotated；Cooperated simply using this inlay card mode of steel ball 7, and steel ball 7 uses
Service life is long, while stable structure will not there is a situation where be broken.
6 uniform intervals of dome-type recess portion are disposed with same circular section that is multiple and being in planet pin 1, and groove 4 is right
Answering dome-type recess portion 6, also uniform intervals arrangement is multiple.In order to ensure stable structure, can be arranged in the border of planet pin 1 multiple
Dome-type recess portion 6 and steel ball 7, it is ensured that transmission effect.
It is clearance fit between the steel ball 7 and dome-type recess portion 6, a quarter ball slot 42.Clearance fit can be really
Protecting steel ball 7 will not be stuck, but can be carried out small angle rotation, and radially can slightly move in planet pin 1, at this time not
It is to belong to rigidly connected state, and can slightly roll and slight displacement, planet carrier 2 can be also driven while guarantee will not be broken
Rotation.
The upper surface of the planet carrier 2 offers mounting hole, and cover board 5 is made up of bolt and mounting hole and connects.
