Embodiment Construction

[0014] Such as figure 1 It is a structural schematic diagram of the present invention, figure 2 A partial enlarged view of the friction surface of the rim, a high-efficiency worm gear, including a wheel 1 and a rim 2. The rim 2 is tooth-shaped and evenly distributed on the outer surface of the wheel body 1. The rim 2 is provided with convex teeth 3 and concave teeth. Slot 4. The convex teeth 3 are hemispherical protrusions, evenly distributed on the friction surface of the wheel rim 2 . The grooves 4 are hemispherical pits evenly distributed on the friction surface of the rim 2 . The diameter of the protruding tooth 3 is consistent with the diameter of the groove 4 . The protruding teeth 3 and the grooves 4 are distributed at intervals.

[0015] Change the smooth design of the friction surface of the worm wheel flange 2 to a concave-convex design, and use it with the worm designed with the same concept. When the worm wheel and the worm mesh to transmit power, the convex t...

Abstract

The invention relates to the technical field of mechanical transmissions, in particular to an efficient worm gear which comprises a gear body and a rim. The rim is toothed and is uniformly distributed on the circumferential surface of the gear body, and convex teeth and grooves are arranged on the rim. The convex teeth and the grooves are arranged on a friction surface of the rim of the worm gear, and sliding friction is greatly reduced; when the efficient worm gear and a worm designed according to an identical idea are used together, convex teeth and grooves of the worm are respectively meshed with the convex teeth and the grooves of the efficient worm gear, and the power transmission efficiency can be greatly improved; and accordingly, friction, heating and abrasion are reduced, and the service life of the efficient worm gear is prolonged.

Description

technical field [0001] The invention relates to the technical field of mechanical transmission devices, in particular to a high-efficiency worm gear. Background technique [0002] At present, the worms and worm gears in the known worm gears and worm gears all have gear teeth, which are contacted by sliding friction during operation to transmit power, so the transmission efficiency is low, the friction force is large, and the heat generation is high, causing serious wear and tear, and the service life is greatly improved. reduce. Contents of the invention [0003] In order to overcome the disadvantages of low efficiency, large wear and serious heat generation of the existing worm gear, the invention provides a high-efficiency worm gear. [0004] The technical solution adopted by the present invention to solve the technical problem is: a high-efficiency worm gear, including a wheel body and a rim, the rim is tooth-shaped, evenly distributed on the outer circular surface of ...
