Abstract

The invention discloses a closed non-circular gear pitch curve design method capable of realizing quick start and sudden stop, which comprises the following steps: designing a pitch curve of a non-circular gear pair in a working stage (2) according to a given non-uniform speed ratio transmission relationship serving as a design basis; establishing pitch curve mathematical models of a non-circular gear pair starting stage (1) and a sudden stop stage (3) according to differential and kinematics according to non-uniform transmission design requirements of quick starting and sudden stop; and finally, according to a variational method and an Euler equation of a fixed boundary condition, solving the pitch curve of the non-circular gear pair in a starting stage and a sudden stop stage, and realizing the design of the closed non-circular gear pair pitch curve with quick starting and sudden stop characteristics. According to the invention, the closed design is more free and flexible, the closed non-circular gear pair pitch curve meeting any given non-uniform speed ratio transmission design requirement can be designed by modifying the boundary conditions of the pitch curve in the working stage, it is ensured that the non-circular gear pair has the characteristics of quick start and sudden stop, and the transmission efficiency of the non-circular gear pair can be improved.

Description

technical field [0001] The invention belongs to the field of non-circular gear design, and in particular relates to a design method of a pitch curve of a closed non-circular gear that can realize quick start and emergency stop. Background technique [0002] The non-circular gear pair is mainly used to realize the non-uniform speed ratio transmission relationship between two shafts. The design of the pitch curve of the driving and driven gears of the gear pair is the basis of the geometric design of non-circular gears and the first priority to meet the design requirements of specific non-uniform speed ratio transmission. [0003] There are two types of pitch curves of non-circular gears: non-closed and closed. The pitch curve of closed non-circular gears can realize continuous rotary motion and is widely used in mechanical equipment. However, the existing closed pitch curve design method cannot meet any given non-uniform speed transmission design requirements. Quick return ...
