Embodiment Construction

[0018] Through the following description in conjunction with the accompanying drawings, the present invention will be clearer, 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 the main cutting edge of a cutter tooth of a cycloid bevel gear. The specific implementation steps are as follows:

[0020] 1Traditional linear cutter tooth cutting edge model

[0021] Traditional machining of cycloid bevel gears often uses linear cutting edges, and then modifies the gear teeth by adjusting the size parameters of the machine tool. This 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 cutter tooth, the convex and concave surfaces of the cutter tooth respectively cut the concave and convex surfaces of the gear, 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 the main cutting edge of a cutter tooth of a cycloid bevel gear, which belongs to the field of mechanical design and manufacturing. Background technique [0002] Cycloidal bevel gears (Klingelnberg) are one of the two commonly used spiral bevel gears, especially in the heavy-duty and high-power transmission fields of aviation, automobiles and heavy-duty machine tools. As the mechanical transmission system is increasingly moving towards high speed and precision, as a key transmission component in the transmission system, cycloid bevel gears often work under complex conditions such as heavy load, impact and variable load, so the tooth surface Problems such as vibration failure and noise will follow. Therefore, cycloid bevel gears have been widely concerned and studied by relevant experts and scholars from various countries, and have become the key technology and commanding heights in gear production....
