Description
Technical Field
The invention belongs to the technical field of machinery, and particularly relates to a composite gear.
Background
Gears are mechanical elements that continuously mesh to transmit motion and power. The existing gear is generally of an integrated structure, so that the strength of the existing gear is guaranteed, but the existing gear is made of a metal material integrally, so that the cost of the existing gear is higher.
Particularly, the requirement on the body strength of the gear body is not high on the occasions of low-strength power transmission. If an integral metal gear is adopted, the cost is higher.
Disclosure of Invention
In view of the above, the present invention provides a compound gear that can solve the above-described problems.
The utility model provides a compound gear, includes body, connecting cylinder and reference column, body and connecting cylinder all are cylindricly, the body outside is equipped with the tooth of a plurality of circumference equipartitions, the body cover is located the connecting cylinder outside is just the connecting cylinder with body tip looks parallel and level, reference column inner connect in the connecting cylinder outside, the reference column outer end inlay in this is internal, the connecting cylinder inboard is equipped with along its recessed keyway of axial, the connecting cylinder lateral wall is equipped with the connecting hole that runs through, reference column inner connect in the connecting hole.
Further, the body is made of nylon.
Further, the connecting cylinder is made of metal materials.
Further, the material of the connecting cylinder is copper.
Further, the connecting cylinder is made of cast iron.
Furthermore, the positioning column is connected with the connecting hole of the connecting cylinder through threads.
Furthermore, the outer end of the positioning column is provided with a clamping structure clamped with the body.
Furthermore, the joint structure includes the convex fender edge in reference column outer end.
Compared with the prior art, the composite gear provided by the invention is connected through the positioning column, can be stably connected with the shaft parts, has lower cost, and can stably connect the connecting cylinder with the shaft parts through the key groove and the key corresponding to the key groove.

Detailed Description
Specific examples of the present invention will be described in further detail below. It should be understood that the description herein of embodiments of the invention is not intended to limit the scope of the invention.
Fig. 1 is a schematic structural diagram of a composite gear according to the present invention. The utility model provides a compound gear, includes body 10, connecting cylinder 20 and reference column 30, body 10 and connecting cylinder 20 all are cylindricly, the body 10 outside is equipped with the tooth of a plurality of circumference equipartitions, the body 10 cover is located the connecting cylinder 20 outside just the connecting cylinder 20 with body 10 tip looks parallel and level, reference column 30 the inner connect in the connecting cylinder 20 outside, reference column 30 outer end inlay in the body 10, connecting cylinder 20 inboard is equipped with along its axially recessed keyway 21, connecting cylinder 20 lateral wall is equipped with connecting hole 22 that runs through, reference column 30 the inner connect in connecting hole 22. The body 10 is made of nylon. The connecting cylinder 20 is made of a metal material. The body 10 is connected with the connecting cylinder 20 through the positioning column 30, the connecting cylinder 20 is made of metal materials and can be stably connected with shaft parts, and the body 10 is made of nylon materials and has lower cost under the requirement of full low-strength power transmission. The key slot 21 and the corresponding key can stably connect the connecting cylinder 20 and the shaft part together.
The material of the connecting cylinder 20 is copper.
The connecting cylinder 20 is made of cast iron.
The positioning column 30 is connected with the connecting hole 22 of the connecting cylinder 20 through a screw thread. The inner end of the positioning column 30 is connected with the connecting hole 22 through threads, and then the positioning column 30 can be stably and fixedly connected to the side part of the connecting cylinder 20.
The outer end of the positioning column 30 is provided with a clamping structure clamped with the body 10. The body 10 and the connecting cylinder 20 can be stably connected together through a clamping structure.
The clamping structure comprises a blocking edge 31 protruding from the outer end of the positioning column 30. The retaining edge 31 can improve the connection stability between the body 10 and the connecting cylinder 20. Of course, the body 10 of nylon material is molded at the outside of the connector barrel 20 by the existing injection molding process during the manufacturing process.
Compared with the prior art, the composite gear provided by the invention is connected through the positioning column 30, can be stably connected with the shaft parts, has lower cost, and can stably connect the connecting cylinder 20 with the shaft parts through the key groove 21 and the corresponding key.
The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the scope of the present invention, and any modifications, equivalents or improvements that are within the spirit of the present invention are intended to be covered by the following claims.
