Abstract

The invention provides a convex-concave meshing pure rolling spiral bevel gear mechanism for cross shaft transmission. The convex-flat meshing pure rolling spiral bevel gear mechanism comprises a small gear and a large gear, and the small gear and the large gear form a transmission pair. The small gear is fixedly connected with a drive through an input shaft, and the large gear is connected with an output shaft. The axis of the small gear intersects with the axis of the large wheel, and n1 uniformly distributed convex spiral circle-arc teeth are arranged on the outer surface of a cone of the small gear. The center lines of all the spiral circle-arc teeth are equal pitch conical spiral lines, and transitional fillets are arranged between the spiral circle-arc teeth and the outer surface ofthe cone of the small gear. n2 uniformly distributed spiral arc grooves are formed in the outer surface of a cone of the large gear, and the center lines of all the spiral arc grooves are equal pitchconical spiral lines. Transitional fillets are arranged between the spiral arc grooves and the outer surface of the cone of the large gear, and the engagement system of the spiral circle-arc teeth ofthe small gear and the spiral arc grooves of the large gear is pure rolling meshing transmission of point contact. The convex-flat meshing pure rolling spiral bevel gear mechanism for the cross shafttransmission has the beneficial effects that transmission efficiency is high, contact ratio is large, carrying capacity is high, and the convex-flat meshing pure rolling spiral bevel gear mechanism for the cross shaft transmission can be widely applied to the fields of small, micro machines and conventional machines which are not easy to lubricate.

Description

technical field

[0001] The invention relates to a bevel gear transmission device, in particular to a convex-concave engagement 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 ...
