Abstract

The invention discloses a modeling method of a non-linear contact arc tooth surface, which comprises the following steps of: establishing a convex circular arc turning tool and a worm coordinate system; establishing The worm tooth surface equation, and obtaining the worm axial tooth profile equation and the worm normal tooth profile equation; establshig The meshing coordinate system of worm gear and worm is established, and establishing the transformation relation of each coordinate system; Establishing a worm gear tooth surface equation; According to the established worm gear and worm arc tooth surface equations, simulating the three-dimensional entity of worm gear arc tooth surface, worm arc tooth surface and worm gear-worm transmission pair arc tooth surface. According to the established worm gear and worm arc tooth surface equation, the invention adopts MATLAB software for data processing and simulation to construct the arc tooth surface with low induced curvature, lubrication angle closer to 90 DEG and more easy to form oil film, which establishes a good foundation for manufacturing and modifying the arc tooth worm gear tooth surface.

Description

technical field

[0001] The invention relates to the technical field of worm gear machining, in particular to a modeling method for nonlinear contact arc tooth surfaces. Background technique

[0002] Worm gear transmission is a transmission type characterized by compact size and large speed ratio. It is often used to transmit motion and power between two interlaced shafts, and is widely used in modern industry. Since the worm gear mechanism is driven by sliding friction, more heat will be generated during operation, which will cause differences in thermal expansion among the parts in the transmission mechanism, which will easily cause lubricating oil leakage, so that the gears cannot get proper lubrication protection, causing mechanical damage. Abrasion or even damage affects the performance of the worm gear transmission mechanism in practical applications, making it unable to work stably for a long time or frequently breaking down during the transmission process.
