Double-cone ring

Abstract

The invention provides a double cone ring, which belongs to the technical field of machinery. It solves the problems of poor wear resistance of the existing double-cone ring and the like. The double cone ring includes a ring-shaped body, the outer peripheral surface and the inner peripheral surface of the body are conical, and the outer peripheral surface of the body is arranged parallel to the inner peripheral surface of the body on the axial section of the body, and the side surface with a large outer diameter of the body There are several projections extending axially and evenly distributed in the circumferential direction, and the outer peripheral surface and the inner peripheral surface of the main body are attached with a molybdenum surface layer formed by spraying molybdenum wire. The invention has the advantages of good wear resistance and high synchronization performance.

Description

technical field [0001] The invention belongs to the technical field of machinery and relates to a synchronizer accessory, in particular to a double cone ring. Background technique [0002] Chinese patent literature discloses a combined synchronous device [application number: 201520920137.9; authorized announcement number: CN205136417U], which includes a shift gear, the shift gear has a spline hole in the axial direction and the shift gear is circumferentially meshed with teeth The outer peripheral surface of the ring gear is provided with gear slots, and both sides of the shift gear are provided with bevel teeth. There are several protrusions passing through the bevel teeth uniformly in the direction. The outer peripheral surface of the gear ring has transition teeth. The chute 2 in the axial extension direction, chute 1 and chute 2 are equipped with sliders, the inner peripheral surface of the ring gear is provided with a sliding hole for the slider to pass through, and th...

AI Technical Summary

Problems solved by technology

[0003] In the above combined synchronizing device, the outer peripheral surface and the inner peripheral surface of the synchronous ring (that is, the double cone ring) are conical, which increases the synchronous performance, but the friction coefficient of the outer peripheral surface and the inner peripheral surface of the synchronous ring is low, and the synchronous performance There is still room for improvement, and the wear resistance is not ideal. In addition, the outer and inner peripheral surfaces of the synchronous ring adopt surface contact. Due to the problems of machining accuracy and guiding accuracy, it is difficult to ensure the effective contact area and affect the synchronous performance. The wear debris generated in the process is not easy to discharge, which affects the working stability
