Embodiment Construction

[0073] The present invention is described in detail below in conjunction with accompanying drawing:

[0074] The shape of the tooth surface of a hypoid gear can be in various forms, as long as the curved surface meets the principle of conjugate meshing transmission, it may be used as the tooth surface of a hypoid gear. Like the spiral bevel gear, the parameters that characterize the geometric shape of the tooth surface such as the tooth profile, tooth line, and tooth profile angle of the hypoid gear usually correspond to the gear cutting method under the premise of meeting the transmission performance requirements. As mentioned above, the complex shape of the tooth surface of the hypoid gear in the prior art makes design and cutting difficult, especially the processing and manufacturing of large gears is even more difficult. The present invention proposes a plane envelope ruled surface hypoid gear transmission form, aiming to use simple tools and simple machine tool movements ...

Abstract

The invention discloses a design method of a hypoid gear pair, aiming at solving the problem of difficulty in designing the hypoid gear pair by using the prior art. The design method of the hypoid gear pair comprises the following steps: 1, taking a plane as a hypoid gear pair transmission forming principle for a big gear tooth surface; 2, determining the geometric technical parameters of a big gear tooth surface shape; 3, determining the geometric technical parameters of a small gear tooth surface shape; and 4, since the gear parameters refers to right-handed rotation of a big gear and left-handed rotation of a small gear, when the big gear is in right-handed rotation and the small gear is in left-handed rotation, dereferencing opposite numbers for the parameters related to the y axle in the parameters. The determination of the geometric technology parameters of the big gear tooth surface shape comprises the following steps: definition of representing the geometric parameters of the big gear tooth surface shape, determination of the coordinates of an M point, determination of the component expression formula of a vector shown in the specification, solution of a tooth-shaped unit vector shown in the specification, solution of another tooth-shaped unit vector shown in the specification, solution of the normal vector shown in the specification one side tooth surface sigma2, determination of the equation of the one side tooth surface sigma2, determination of the equation of the other side tooth surface sigma1, determination of the equation of a tooth surface sigma1theta and formation of the gear teeth of the gear in array.

Description

technical field [0001] The invention relates to a design method of a gear pair, more precisely, the invention relates to a design method of a hypoid gear pair. Background technique [0002] In the space-staggered shaft transmission, the hypoid gear pair based on the theory of space-staggered shaft transmission usually uses a relatively simple conical surface instead of a single leaf hyperboloid as the indexing surface, and cuts teeth on the surface. It constitutes a hypoid-conical gear transmission, in which the bevel gears are mostly arc teeth and cycloidal teeth. The methods of Gleason and Olikon are the most widely used in the design and machining of hypoid gear pairs. [0003] The shape of the tooth surface of the hypoid gear can be in various forms, as long as the curved surface satisfies the principle of conjugate mesh transmission, it may be used as the tooth surface. Like the spiral bevel gear, the parameters that characterize the geometric shape of the tooth surfa...
