Abstract

The invention provides a convex-convex engaged pure rolling helical bevel gear mechanism for cross shaft transmission. The convex-convex engaged pure rolling helical bevel gear mechanism comprises a pinion and a main gear which form a transmission pair; the pinion is fixedly connected with a driver through an input shaft; the main gear is connected with an output shaft; the axis of the pinion is intersected with the axis of the main gear; the conical outer surface of the pinion is provided with n1 helical circular arc teeth which are distributed uniformly; the center lines of all helical circular arc teeth all are equal-lift conical helical lines; a transition fillet is arranged between the helical circular arc teeth and the conical outer surface of the pinion; the conical outer surface ofthe main gear is provided with n2 helical circular arc teeth which are distributed uniformly; the center lines of all helical circular arc teeth all are equal-lift conical helical lines; a transitionfillet is arranged between the helical circular arc teeth and the conical outer surface of the main gear; and the helical circular arc teeth of the pinion and the helical circular arc teeth of the main gear are engaged in a point-contact pure rolling engagement transmission manner. The convex-convex engaged pure rolling helical bevel gear mechanism provided by the invention has the beneficial effects of being high in transmission efficiency, large in overlap ratio, high in bearing capacity and widely applied to the fields of tiny machinery, micro machinery and general machinery which are difficult to lubricate.

Description

technical field

[0001] The invention relates to a bevel gear transmission, in particular to a convex-convex meshing pure rolling helical bevel gear mechanism for cross shaft transmission. Background technique

[0002] As the core basic components of machinery, gears are widely used in machine tools, automobiles, robots, wind power, coal mines, aerospace and other equipment manufacturing fields and the main battlefield of the national economy. Their performance directly determines the quality of major equipment and high-end industrial products. performance and reliability.

[0003] At present, the main problem facing my country's gear industry is the obvious lack of design and manufacturing capabilities for high-efficiency, large-carrying capacity, lightweight, and high-reliability high-performance gear products. The traditional spur gears, helical gears and bevel gear pairs widely used in the field of industrial production and manufacturing have never completely solved the ...
