Abstract
The invention provides a ratchet wheel. The ratchet wheel comprises a circular body and pawls, wherein a through hole is formed in the circular body; the pawls are annularly distributed on the edge of the body and are arranged irregularly; the through hole is formed in the axis of the body and penetrates through the body; a keyway is formed on the inner wall surface of the through hole along the longitudinal extension direction of the body in a concave way; and a plane is formed at the tail end of each pawl. Through the structure, the strength of the pawls is improved effectively, and the load bearing capacity of the ratchet wheel is improved.
Description
Technical field
The present invention relates to mechanical field, relate in particular to a kind of ratchet.
Background technique
As everyone knows, ratchet is a kind of unidirectional drive parts.It can through lock pawl and ratchet each other against, with realization unidirectional drive or stop.Ratchet comprises: body and being periphery in said body edges and the rule ratchet of arranging.In the existing technology, the situation of fracture in use often takes place in the ratchet in the ratchet.
In view of this, be necessary ratchet of the prior art is improved, to address the above problem.
Summary of the invention
The object of the present invention is to provide a kind of ratchet, it can improve the intensity of ratchet, to improve the ability of ratchet bearing load.
For realizing the foregoing invention purpose, the invention provides a kind of ratchet, comprising:
Circular body, its inside is provided with a through hole;
Be periphery in said body edges and regular ratchet of arranging;
Said through hole is arranged at the axle center of said body and connects said body, and the internal face of said through hole is along being concaved with a keyway on the said body lengthwise bearing of trend, and the end of said ratchet is provided with a plane.
As further improvement of the present invention, said ratchet is along the thickness of the thickness on the said body lengthwise bearing of trend less than said body.
As further improvement of the present invention, said keyway connects the two ends end face of said body fully.
As further improvement of the present invention, the degree of depth of said keyway is thickness half the of the sidewall of said body.
As further improvement of the present invention, the groove angle of said ratchet is 60 degree.
As further improvement of the present invention, the tooth drift angle of said ratchet is 0 degree.
Compared with prior art, the invention has the beneficial effects as follows: through this structure, improved the intensity of this ratchet effectively, improved the ability of ratchet bearing load.
Description of drawings
Fig. 1 is the front view in ratchet one embodiment of the present invention;
Fig. 2 is the sectional view along A-A line among Fig. 1.
Embodiment
Below in conjunction with each mode of execution shown in the drawings the present invention is elaborated; But should be noted that; These mode of executions are not limitation of the present invention; The function that those of ordinary skills do according to these mode of executions, method, or structural equivalent transformation or substitute all belong within protection scope of the present invention.
Please join shown in Figure 1ly, wherein Fig. 1 is the front view in ratchet one embodiment of the present invention.In this mode of execution, a kind of ratchet 10, it comprises: circular body 1, its inside is provided with a through hole 31; Be periphery in said body 1 edge and regular ratchet 2 of arranging.
Wherein, this through hole 31 is arranged at the axle center of said body 1 and connects said body 1, and the internal face of this through hole 31 is along being concaved with a keyway 311 on the body 1 lengthwise bearing of trend.This ratchet 10 can cooperatively interact with rotating shaft (not shown) and key (not shown), makes whole ratchet 10 along with rotating shaft pivots together, and through lock pawl (not shown) and ratchet 2 each other against, to realize the unidirectional drive or the stop of ratchet 10.More specifically, the end of this ratchet 2 is provided with a plane 21.
Shown in Figure 2 in conjunction with reference, this ratchet 2 is along the thickness of the thickness on said body 1 lengthwise bearing of trend less than said body 1.Simultaneously, this keyway 311 connects the two ends end face 1a of said body 1,1b fully.
In this mode of execution, the degree of depth of this keyway 311 is thickness half the of the sidewall of said body 1.
More specifically, the groove angle of this ratchet 2 is 60 degree, and the tooth drift angle of this ratchet 2 is 0 degree, with unidirectional drive or the stopping effect that improves this ratchet 10 further.
The listed a series of detailed description of preceding text only is specifying to feasibility mode of execution of the present invention; They are not in order to restriction protection scope of the present invention, allly do not break away from equivalent mode of execution or the change that skill of the present invention spirit done and all should be included within protection scope of the present invention.
To those skilled in the art, obviously the invention is not restricted to the details of above-mentioned example embodiment, and under the situation that does not deviate from spirit of the present invention or essential characteristic, can realize the present invention with other concrete form.Therefore; No matter from which point; All should regard embodiment as exemplary; And be nonrestrictive, scope of the present invention is limited accompanying claims rather than above-mentioned explanation, therefore is intended to the implication of the equivalents that drops on claim and all changes in the scope are included in the present invention.Should any reference character in the claim be regarded as limit related claim.
In addition; Describing according to mode of execution though should be appreciated that this specification, is not that each mode of execution only comprises an independently technological scheme; This narrating mode of specification only is for clarity sake; Those skilled in the art should make specification as a whole, and the technological scheme among each embodiment also can form other mode of executions that it will be appreciated by those skilled in the art that through appropriate combination.
