Abstract

A method for manufacturing a cone-surface-enveloping cone-worm pair, belonging to the technical field of offset worm transmission. The cone surface enveloping cone worm pair includes an enveloping cone worm and a bevel worm gear. The helical surface of the enveloping cone worm is a developable curved surface, which is formed by grinding a disc-shaped cone surface grinding wheel. The enveloping cone worm and bevel worm gear mesh. , the cone-surface enveloping cone-worm pair is suitable for transmission ratio i 12 When the axes are orthogonally or non-orthogonally offset by ≥10; the manufacturing method of the cone-surface enveloping cone worm pair includes: step 1. setting the coordinate parameters of the enveloping cone worm to be manufactured; step 2. manufacturing the package Enveloping cone worm, Step 3. Set the coordinate parameters of the cone worm gear to be manufactured, Step 4. Manufacturing the cone worm gear and Step 5. Assemble the cone surface enveloping cone worm pair. The tooth surfaces of the cone-surface enveloping cone worm pair are not prone to curvature interference, are suitable for a wide range of worm heads and transmission ratios, and the instantaneous contact lines are evenly distributed, sparse, and non-intersecting, which is beneficial to heat dissipation and lubrication, and has a large load-bearing capacity. High transmission efficiency and long service life.

Description

technical field

[0001] The invention relates to the technical field of offset worm transmission, in particular to a method for manufacturing a cone enveloping cone worm pair. Background technique

[0002] The helical surface of the classic cone-worm screw is formed by turning with a straight-edge turning tool. It is a non-developable ruled surface, and it is difficult to precisely grind according to the forming principle. This is not conducive to the finishing of the helical surface of the bevel worm after hardening, and is also not conducive to further improving the load-carrying capacity of the transmission pair. The meshing boundary of the classic bevel-worm drive may enter the bevel-worm tooth flank, thereby creating an unusable zone, and this part of the corresponding bevel-worm gear face will cause the mating bevel-worm gear tooth flank to undercut. Furthermore, the ability to control the asymmetry of the flank meshing of a tooth is not ideal for a classic bevel-worm ...
