Description

A kind of ring gear sealing block

Technical field

The utility model relates to shift fork ring gear technical fields, and in particular to a kind of ring gear sealing block.

Background technique

The shift fork of existing starter generallys use baffle, sealing block compresses sealing, and not only structure is complicated, but also sealing effect It is bad with fixed effect.

Utility model content

The purpose of the utility model is to overcome above-mentioned technical deficiencies, provide a kind of ring gear sealing block, solve existing skill The seal structure complex of shift fork and the bad technical problem of sealing effect fixed effect in art.

To reach above-mentioned technical purpose, the technical solution of the utility model provides a kind of ring gear sealing block, including internal tooth Circle ontology and bracket, the bracket are connected on the outer wall of the ring gear ontology, offer on the bracket and shift fork Handle set matches and is used to push down the groove of the shift fork, and the groove seals the mounting hole on the handle set.

Compared with prior art, the beneficial effects of the utility model include: the utility model by baffle, sealing block, internal tooth Circle and ring gear bracket are integrated, and open up groove on bracket, and the handle set of groove and shift fork matches, therefore can rise To the effect of fixed shift fork, while the mounting hole on handle set being covered using groove, plays sealing function.The utility model mentions The ring gear sealing block of confession has the technical effect of simple for structure, sealing effect and good fixing effect

Specific embodiment

In order to make the purpose of the utility model, technical solutions and advantages more clearly understood, below in conjunction with attached drawing and implementation Example, the present invention will be further described in detail.It should be appreciated that specific embodiment described herein is only to explain this Utility model is not used to limit the utility model.

Embodiment 1:

As shown in Figure 1, the embodiments of the present invention 1 provide a kind of ring gear sealing block, including ring gear ontology 1 with And bracket 2, the bracket 2 are connected on the outer wall of the ring gear ontology 1, and the hand with shift fork 10 is offered on the bracket 2 Handle seat 101 matches and the groove 21 for pushing down the shift fork 10, the groove 21 seal the installation on the handle set 101 Hole.

The function of baffle in the prior art, sealing block, ring gear and bracket is integrated by the utility model, in bracket Groove 21 is opened up on 2, groove 21 and the handle set 101 of shift fork 10 match, to substitute the work that baffle plays fixed shift fork 10 With, and then the mounting hole on handle set 101 is covered by groove 21, replacement seal block plays sealing function.So that shift fork is whole Body structure is more simplified, and is easy to use.

Preferably, as shown in Figure 1, the bracket 2 is an integral molding structure with the ring gear ontology 1.

Integrated formed structure is stronger.Specifically, the bracket 2 uses plastic pallet, the ring gear ontology 1 is used Plastics ring gear, compared with the prior art in metal material bracket and ring gear, plastic pallet and plastics ring gear weight Lighter, cost is lower, it is easy to accomplish.

Preferably, as shown in Fig. 2, further including buffer gasket 3, the buffer gasket 3 be set to the groove 21 with it is described Between handle set 101.

Increase buffer gasket 3, strength when buffer starting machine starts reduces vibration, reduces the mill of shift fork 10 and bracket 2 Damage, prolongs the service life.

Preferably, as shown in Fig. 2, the buffer gasket 3 includes annular ring 31, uniformly divide in the circumferential direction of annular ring 31 The multiple buffering spacers 32 of cloth, are provided with buffer stopper 33 on each buffering spacer 32, and the buffer stopper 33 is towards described recessed Slot 21 is arranged.

The thickness of buffer stopper 33 is greater than the thickness of buffering spacer 32, also greater than the thickness of annular ring 31, therefore, buffer stopper 33 Buffer function can be preferably played, the space among each buffer stopper 33 forms cushion space.

Preferably, the card slot to match with the buffer stopper 33 is offered on the groove 21, card slot is not shown in the figure, institute Buffer stopper 33 is stated to engage with the card slot.

The card slot to match with buffer stopper 33 is set, so that buffer gasket 3 is easy to position during installation, in use process not It easily walks, preferably plays the role of bumper and absorbing shock.

Preferably, as shown in Fig. 2, the lateral surface of the lateral surface of the buffering spacer 32 and the buffer stopper 33 is circle Cambered surface.

Arc surface is more matched with the shape of 101 shape of handle set of shift fork 10 and groove 21 so that buffer gasket 3 with Compatible degree before handle set 101 and groove 21 is higher, and the effect of bumper and absorbing shock is more preferable.

Specific embodiment of the present utility model described above does not constitute the restriction to scope of protection of the utility model. Any other various changes and modifications that any technical concept according to the present utility model is made should be included in practical In novel scope of protection of the claims.
