Description

End face driving bevel gear tooth-shaped connecting structure

Technical Field

The invention relates to an end face driving bevel gear tooth-shaped connecting structure.

Background

The end face teeth mainly transmit motion and power through continuous meshing of teeth, one of the most widely applied transmission modes in modern equipment and the automobile industry is that the end face teeth are straight grooves and straight teeth directly manufactured on the end face of a shaft at present, and in order to avoid other parameter changes of the shaft, the lengths of the teeth and the grooves are short, the stress surface is small, the transmission stability is poor, the wear resistance is poor, and the service life is short. And the terminal surface of two terminal surface teeth that the meshing is in the same place all is the plane, and the plane roughness is poor, causes the contact position of point or line more, further causes the stress surface to diminish, and transmission stability and wearability are poor, and the life-span is short. The plane flatness is poor, noise is easy to generate in the transmission process, and the comfort of the whole transmission system is influenced. The whole process is complicated due to high requirements on the plane flatness. The automatic centering function is not provided, so that the deviation caused by the non-concentricity of the connecting piece is easily caused, and the rotating connecting piece is caused to jump; in order to guarantee the service life, the axial size is larger, and the rotary joint is not suitable for occasions with higher rotating speed and higher power.

Disclosure of Invention

The invention aims to solve the problems in the prior art and provide a novel wear-resistant rubber belt which has the advantages of large stress surface, good transmission stability, strong wear resistance and long service life; the end face driving bevel gear tooth-shaped connecting structure has the advantages of greatly shortening the axial size, having a self-centering function, avoiding the jumping caused by rotation, having low noise and simple manufacturing process, and is suitable for occasions with higher rotating speed and higher power rotation connection.

In order to achieve the purpose, the technical solution of the invention is as follows: an end face driving bevel gear tooth-shaped connecting structure comprises a component I and a component II, wherein parameters of the component I and the component II are completely matched; the outer end part of the end face of the component I is an externally tangent inclined circular ring-shaped inclined plane I, a plurality of inclined conical teeth I are uniformly and convexly arranged on the circular ring inclined plane I, conical grooves I are formed among the conical teeth I, and the conical teeth I and the conical grooves I form bevel gears; the outer end part of the end face of the component II is an inwards concave inclined circular inclined plane II; the width and the inclination angle of the inclined plane II are the same as those of the inclined plane I; conical grooves II which are the same in number as the conical teeth I and are matched with the conical teeth I are uniformly and inwards recessed on the inclined plane II, the conical teeth II which are matched with the conical grooves I are arranged among the conical grooves II, and each conical tooth II and each conical groove II form an inwards recessed bevel gear; the component I and the component II are axially pressed, and the bevel gear and the concave bevel gear are completely meshed together.

Further preferably, gaps are arranged between the conical teeth I and the conical grooves II and between the conical teeth II and the conical grooves I in a matched mode at the bottoms of the grooves. Prevent the interference from assembling badly.

Further preferably, the upper end surfaces of the bevel teeth I and the bevel teeth II are plane or arc transition surfaces, the inner end surfaces and the outer end surfaces are planes, and the two side surfaces are in an asymptotic line shape. The contact of awl tooth I and awl tooth II is the face contact to the great moment of torsion of transmission increases wear-resisting life, makes the stability of product better.

The bevel gear on the end face of the component I and the concave bevel gear on the end face of the component II are inclined, and compared with the existing straight groove and straight tooth, the bevel gear on the end face of the component I and the concave bevel gear on the end face of the component II have the advantages that the length can be made very long under the condition of the same thickness and width, so that the stress surface between the bevel tooth I and the bevel tooth II is very large, the transmitted torque is large, the axial size can be greatly shortened under the condition of achieving the same function with the straight groove and the straight tooth in the prior art, the bevel gear is compact and reliable, the weight of a shaft is reduced to a certain degree, and the bevel gear is more easily made to be suitable for occasions of high-speed and high-power rotary connection; the stress is uniform, the failure caused by stress concentration can be avoided, the self-centering function is realized, the jumping caused by rotation is avoided, the transmission stability is good, the wear resistance is good, the noise is reduced, and the service life is prolonged; the manufacturing process is simple through precision forging.
