Description
Technical Field
The utility model is applied to the technical field of engine chain wheels, and particularly relates to a stator chain wheel for an engine.
Background
The sprocket is a wheel with cogged sprocket teeth for meshing with precisely pitched blocks on a chain link or cable. The chain wheel is widely applied to mechanical transmission and the like in the industries of chemical engineering, textile machinery, escalators, wood processing, three-dimensional parking garages, agricultural machinery, food processing, instruments, petroleum and the like.
In the automobile parts manufacturing field, the sprocket in the engine is taken as the key part, then the more tired more high the requirement to the sprocket, but current engine output sprocket has the structure unreasonable, and life is low, and is comparatively troublesome when processing manufacturing to improve manufacturing cost.
SUMMERY OF THE UTILITY MODEL
The utility model aims to provide a stator chain wheel for an engine, which solves the problems that the existing engine output chain wheel is unreasonable in structure, low in service life and troublesome in processing and manufacturing, so that the manufacturing cost is increased.
In order to achieve the purpose, the utility model adopts the technical scheme that:
the utility model provides a stator chain wheel for an engine, which comprises a chain wheel body, wherein the chain wheel body is arranged in a circular ring shape, chain wheel teeth are arranged on the outer peripheral wall of the chain wheel body, a plurality of convex blocks are arranged on the inner peripheral wall of the chain wheel body, a cavity for fixing a rotor is formed by enclosing the radial inner end surfaces of the convex blocks, a fixing through hole is formed in each convex block, the fixing through holes are arranged in a kidney-shaped hole, and positioning convex blocks are arranged on the opposite surfaces of two adjacent convex blocks in the convex blocks.
Further, each lug is provided with a smooth concave surface along the radial inner side surface of the chain wheel body.
Further, the height of the lug is equal to that of the sprocket body.
Due to the application of the technical scheme, compared with the prior art, the utility model has the following advantages:
the stator chain wheel for the engine is simple in structure, simpler to manufacture, low in cost and suitable for mass production.
Drawings
Some specific embodiments of the utility model will be described in detail hereinafter, by way of illustration and not limitation, with reference to the accompanying drawings. The same reference numbers in the drawings identify the same or similar elements or components. Those skilled in the art will appreciate that the drawings are not necessarily drawn to scale. In the drawings:
fig. 1 is a schematic view of the overall structure of the present invention.
Wherein the reference numerals are as follows:
1. a sprocket body; 2. a sprocket tooth; 3. a bump; 4. fixing the cavity; 5. a fixing through hole; 6. and positioning the projection.
Detailed Description
The technical solutions of the present invention will be described clearly and completely with reference to the accompanying drawings, and it should be understood that the described embodiments are some, but not all embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
In the description of the present invention, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc., indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, and are only for convenience of description and simplicity of description, but do not indicate or imply that the device or element being referred to must have a particular orientation, be constructed and operated in a particular orientation, and thus, should not be construed as limiting the present invention. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and are not to be construed as indicating or implying relative importance.
In addition, the technical features involved in the different embodiments of the present invention described below may be combined with each other as long as they do not conflict with each other.
Referring to fig. 1, the stator sprocket for an engine provided by the present invention comprises a sprocket body 1, the sprocket body 1 is arranged in a ring shape, sprocket teeth 2 are arranged on the outer circumferential wall of the sprocket body 1, a plurality of projections 3 are arranged on the inner circumferential wall of the sprocket body 1, a cavity 4 for fixing a rotor is formed by enclosing the radial inner end surfaces of the plurality of projections 3, each projection 3 is provided with a fixing through hole 5, the fixing through hole 5 is arranged in a kidney-shaped hole, positioning projections 6 are arranged on the opposite surfaces of two adjacent projections 3 in the plurality of projections 3, when the stator sprocket is assembled with other components in the engine, the rotor in the engine is assembled in the fixing cavity 4, a positioning groove is arranged on the rotor at a position corresponding to the positioning projection 6, when the rotor and the stator sprocket are assembled together, the positioning projection 6 is matched with the positioning groove, so as to position the rotor, prevent the rotor at 4 internal rotations of fixed die cavity, wherein be provided with the ring flange of being connected with the stator sprocket on the rotor, after rotor and stator sprocket cooperation, the flange dish lid on the rotor is established on the terminal surface of stator sprocket, is provided with set screw in the fixing hole 5, consequently fixes flange plate and the stator sprocket on the rotor together through set screw, and fixed screw 5 is waist type hole setting, and adjustable set screw's position makes flange plate and the more firm of stator sprocket terminal surface fixation.
Further, referring to fig. 1, each of the protrusions 3 is formed into a smooth concave surface along the radial inner side surface of the sprocket body 1, so that the contact area between the protrusion 3 and the rotor can be increased, and the rotor and the stator sprocket can be more stably matched.
Further, referring to fig. 1, the height of the protrusion 3 is equal to the height of the sprocket body 1, so that the flange on the rotor and the end face of the stator sprocket are more tightly covered, and dust and impurities are prevented from entering the stator sprocket when the stator sprocket works.
The above embodiments are merely illustrative of the technical concept and features of the present invention, and the purpose thereof is to enable those skilled in the art to understand the content of the present invention and implement the utility model, and not to limit the scope of the utility model, and all equivalent changes or modifications made according to the spirit of the present invention should be covered by the scope of the present invention.
