Problems solved by technology

Because the cycloidal bevel gear heavy-duty cycloidal bevel gear tooth line along the tooth length direction is an extended epicycloid and the height of the tooth height is equal, because of the particularity of the cycloidal bevel gear tooth shape, the domestic Foreign scholars' analysis rarely involves cycloidal bevel gears

Embodiment Construction

[0018] The present invention will be clearer through the following description combined with the accompanying drawings, and the accompanying drawings are used to explain the methods and embodiments of the present invention.

[0019] The invention provides a contour modification method for machining the main cutting edge of a cycloidal bevel gear. The specific implementation steps are as follows:

[0020] 1 Traditional linear cutter cutting edge model

[0021] In the traditional machining of cycloid bevel gears, straight-line cutting edges are often used, and then the gear teeth are modified by adjusting the size parameters of the machine tool, which not only makes the machining parameters too complicated but also affects the tooth surface profile. The surface profile of the cutting edge of the linear tooth, the convex and concave surfaces of the tooth cut the concave and convex surfaces of the gear respectively, α g Tooth profile angle, arc radius ρ w The rounded corners of...

Abstract

The invention relates to a profile shaping method for machining a cutter tooth main cutting edge according to a cycloid bevel gear, and belongs to the field of machine designing and manufacturing. The method is based on a gear tooth surface machining principle, a gear meshing principle is used, the surface profile of the cutter tooth main cutting edge of a machined tooth surface is modified, and a tooth surface equation is obtained according to space coordinate system changes. A meshing track and a transmission error of a gear tooth machined through a new method is analyzed through a TCA analysis method, and are compared with those of a gear machined through a traditional method, and the gear constructed in the invention is obtained, so that the transmission error is substantially reduced, and meanwhile the better contact track is obtained; and through an experimental verification and analysis method, the constructed gear conducts a loading experiment and analyzes the position of a contact zone, and stress concentration can be avoided through the gear constructed in the invention. Stress concentration during gear meshing is completely avoided, the transmission error is reduced, noise of the gear is reduced accordingly, and the transmission stability is improved.

Description

technical field [0001] The invention relates to a contour modification method for machining the main cutting edge of a cycloidal bevel gear, belonging to the field of mechanical design and manufacturing. Background technique [0002] Cycloidal bevel gear (Klingelnberg) is one of the two most commonly used spiral bevel gears, especially in heavy-duty, high-power transmission fields such as aviation, automobiles and heavy machine tools. As the mechanical transmission system is increasingly developing towards high speed and precision, as a key transmission component in the transmission system, cycloidal bevel gears often work under complex working conditions, such as heavy loads, impacts and variable loads, etc., so the tooth surface Problems such as vibration failure and noise then arise. Therefore, cycloidal bevel gears have been widely concerned and researched by relevant experts and scholars from various countries, and have become the key technology and commanding heights ...
