Abstract
The utility model discloses a drive gear which comprises a gear body, wherein an outer tooth is arranged on the peripheral surface of the gear body; an inner tooth and a convex tooth are respectively arranged in the gear body; the tooth direction of the inner tooth faces the interior of the gear body, and the inner tooth is positioned at the inner end part of the gear body; the tooth direction of the convex tooth faces the exterior of the gear body, and the convex tooth is positioned at the inner middle end part of the gear body; a step is arranged between the inner tooth and the convex tooth; a certain gap is formed between the inner tooth and the step. The drive gear disclosed by the utility model has the advantages that the structure is simple, the inner tooth and the convex tooth can be in tight fit with a transmission shaft, and the work is more stable without generating more noise.
Description
Technical field
The utility model belongs to mechanical transmissioning technology field, especially relates to a kind of actuation gear.
Background technique
Actuation gear is the requisite power transfer units of all kinds of mechanical transmissions, and it has a wide range of applications in each occasion.Existing actuation gear if rely on an inner projection or recessed be in transmission connection and then carry out work with axle, being connected between the actuation gear of this structure and axle is not tight, sealing is poor there will be in working again loosening, so not only cause wearing and tearing larger, and be prone to idle running between gear and gear shaft, have a strong impact on normal work, use for a long time backgear be easily corroded and then cause damage; Also have this structure larger because not tight gear vibrates in the course of the work, while causing work, produce a large amount of noises, affect staff's physical and mental health; Therefore be necessary to be improved.
Model utility content
The purpose of this utility model is the deficiency existing for above-mentioned prior art, provides a kind of simple in structure, and between transmission shaft, is connected fastening actuation gear.
To achieve these goals, the technological scheme that the utility model adopts is: a kind of actuation gear, comprise gear body, the outer circumferential face of described gear body is provided with external tooth, in described gear body, be respectively arranged with internal tooth and double wedge, the teeth directional of described internal tooth towards the inside of gear body and its be positioned at the inner end of gear body, the teeth directional of described double wedge is positioned at the medial end portions of gear body towards the outside of gear body and its; Between described internal tooth and double wedge, be provided with step, between internal tooth and step, there is certain gap.
The planar central point of described external tooth, internal tooth and double wedge is overlapped.
The top of described external tooth, internal tooth and double wedge is provided with plane.
Adopt after said structure, the advantage that compared to the prior art the utility model had is: of the present utility model simple in structure, internal tooth and double wedge can coordinate closely with transmission shaft, and work can more be stablized and can not produce too much noise.
Accompanying drawing explanation
Fig. 1 is plane structure schematic diagram of the present utility model.
Fig. 2 is that sectional view is looked on a left side of Fig. 1.
Embodiment
The following stated is only preferred embodiment of the present utility model, does not therefore limit protection domain of the present utility model, below in conjunction with drawings and Examples, the utility model is further illustrated.
Embodiment, see Fig. 1 to and Fig. 2 shown in: a kind of actuation gear, comprise gear body 10, the outer circumferential face of described gear body 10 is provided with external tooth 11.In described gear body 10, be respectively arranged with internal tooth 12 and double wedge 13, the teeth directional of described internal tooth 12 towards the inside of gear body 10 and its be positioned at the inner end of gear body 10; The teeth directional of described double wedge 13 is positioned at the medial end portions of gear body 10 towards the outside of gear body 10 and its; Transmission shaft can coordinate closely with it like this, then in working, there will not be because of loosening generation and vibrate and then cause wearing and tearing, allows more stable work.Between described internal tooth 12 and double wedge 13, be provided with step 14, between internal tooth 12 and step 14, there is certain gap, and the gap between step 14 can allow internal tooth 12 and the power tooth on transmission shaft have certain slipping space, make it there is better flexibility.The planar central point of described external tooth 11, internal tooth 12 and double wedge 13 is overlapped, and its top is provided with plane, and this plane makes it have better tightness, allows more stable work.
