Abstract
The utility model discloses a profile gear capable of preventing accompanying rotation, and the profile gear comprises an inner hole assembled together with a shaft, wherein an opening along the axial direction is arranged on the wall surface of the outer end of the inner hole; the opening extends to the edge of the outer end to form an opening petal; the aperture of the inner end of the inner hole is matched with the axle diameter of the assembled shaft, and the aperture of the outer end of the inner hole is smaller than the axle diameter of the assembled shaft. The profile gear has the advantages that the profile gear and the assembled shaft are held and fixedly located through the opening arranged on the wall surface of the inner hole of the gear by the facts that the opening petal of the inner hole of the opening has inward and outer elasticity along the radial direction and the aperture of the inner hole of the opening is smaller than the axle diameter of the assembled shaft, and the gear is prevented from rotating under the drive of the other external gears. The profile gear is simple in structure and convenient to assemble, has no additional part, and can achieve the purpose of preventing accompanying rotation at the same time.
Description
Technical field
The utility model relates to a kind of special shape gear that can prevent in company with rotation.
Background technique
Driving force transfer mechanism and have its throttle setting (country origin: China; Publication number: 1439941, the open date: 2003-9-3) disclose and a kind ofly bring into play suitable prevention power and follower do not produce the driving force transfer mechanism of problems such as torque increase and wearing and tearing and have it in the interlock interval that rotation drives throttle setting in company with rotation for what prevent follower.Having wherein: with the cam member of follower one rotation with flexiblely push the resilient member of the camming surface of this cam member in company with rotary preventing mechanism; Said camming surface has: the circular arc portion in the big footpath that resilient member described in the interlock interval slides; Path part with this circular arc portion adjacency; The rib part that this path part is connected with said circular arc portion; The butt position desire of utilizing said resilient member and said camming surface through the load that said rib part produces when the said circular arc portion side shifting, stops said follower state in company with rotation and constitute from said path part side.The resilient member that pushes the camming surface of this cam member is the leaf spring that two ends are fixed, the roughly neutral position of this leaf spring and camming surface butt.
Though the above-mentioned purpose that can effectively reach prevention companion rotation in company with rotary preventing mechanism; But its complex structure; Not only follower is outer will have the special cam member of shape, but also leaf spring need be set, and component increase; No matter be its structure itself or production assembling, all increased no small difficulty.
The model utility content
The model utility purpose: to the problems referred to above, the purpose of the utility model provides a kind of simple in structure can preventing in company with the special shape gear that rotates.
Technological scheme: a kind of special shape gear that can prevent in company with rotation, comprise and the endoporus of axle assembling that the outer end wall of said endoporus is offered one section opening vertically, said opening forms the opening lobe until outer end edges; The aperture of the inner of said endoporus cooperates with the assembled shaft diameter of axle, and the aperture of the outer end of said endoporus is less than the assembled shaft diameter of axle.
The quantity of offering of said opening is at least one.
Beneficial effect: compared with prior art; The utility model has the advantages that the opening of offering through the bore wall; Utilize the opening lobe of this section opening endoporus to have radially inside, outside elasticity; The aperture of this section opening endoporus is held stationary positioned less than the assembled shaft diameter of axle tightly with the axle that is assemblied in wherein simultaneously, prevents the externally drive companion rotation down of other gear of gear.This is simple in structure, does not have other component, can reach the purpose that stops in company with rotation equally, and is easy to assembly.

Fig. 2 is the utility model plan view;
Fig. 3 is the A-A sectional view of Fig. 2;
Fig. 4 is the B-B sectional view of Fig. 2.
Embodiment
Below in conjunction with accompanying drawing and specific embodiment; Further illustrate the utility model; Should understand these embodiments only be used to the utility model is described and be not used in the restriction the utility model scope; After having read the utility model, those skilled in the art all fall within the application's accompanying claims institute restricted portion to the modification of the various equivalent form of values of the utility model.
Shown in accompanying drawing 1-4, a kind of special shape gear that can prevent in company with rotation, Gear center is offered the endoporus 1 with axle assembling, and axle is during with endoporus 1 assembling, enters to outer end 2 by the inner 4 of endoporus 1.The 2 one sections walls in the outer end of endoporus 1 are offered opening 3 vertically, and opening 3 forms the opening lobe until 2 edges, outer end; The aperture D of the inner 4 of endoporus 1
2D cooperates with the assembled shaft diameter of axle, i.e. D
2＞d, the aperture D of one section wall of opening 3
1Less than assembled shaft diameter of axle d.The quantity of offering of opening 3 is at least one, so that the opening lobe at 2 places, outer end has radially inside, outside elasticity.
Claims (2)
1. one kind can prevent the special shape gear in company with rotation; Comprise endoporus (1) with the axle assembling; It is characterized in that: outer end (2) wall of said endoporus (1) is offered one section opening (3) vertically, and said opening (3) forms the opening lobe until edge, outer end (2); The aperture of the inner (4) of said endoporus (1) cooperates with the assembled shaft diameter of axle, and the aperture of the outer end (2) of said endoporus (1) is less than the assembled shaft diameter of axle.
2. a kind of special shape gear that can prevent the companion rotation according to claim 1, it is characterized in that: the quantity of offering of said opening (3) is at least one.
