Embodiment Construction

[0013] 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 lubricating worm gear, including a wheel 1 and a rim 2, the rim 2 is tooth-shaped, evenly distributed on the outer surface of the wheel body 1, and the rim 2 is provided with oil storage holes 3 and Oil tank 4. The oil storage holes 3 are circular pits, which are evenly distributed on the friction surface of the rim 2 . The oil filling grooves 4 are evenly distributed on the friction surface of the rim 2, arranged in a longitudinal row, and parallel to the rim 2. Each oil filling groove 4 runs through all the oil storage holes 3 on the same column.

[0014] When the lubricating oil is sprayed on the friction surface, a part of the lubricating oil adheres to the friction surface of the rim 2, and the other part flows into the oil storage hole 3 and the oil filling groove 4, and will not flow away immediately, prolongin...

Abstract

The invention relates to the technical field of mechanical transmission devices, in particular to a lubricating worm gear. The lubricating worm gear comprises a gear body and a toothed rim, teeth are uniformly distributed on the external circular surface of the gear body, oil storage holes and a plurality of oil filling grooves are arranged on the rim, the oil storage holes which are circular pits are uniformly distributed on the friction surface of the rim and can absorb more lubricating oil, the oil filling grooves penetrate through all oil storage oil holes in the same column, and convergence and running-through of the lubricating oil are facilitated, so that utilization efficiency of the lubricating oil is improved greatly, friction and heating are lowered, and abrasion is reduced.

Description

technical field [0001] The invention relates to the technical field of mechanical transmission devices, in particular to a lubricating worm gear. Background technique [0002] At present, the known worm and gear transmissions mainly rely on oil pool lubrication or use a pump to spray oil on the friction part for lubrication, but the amount of oil in the friction surface is very small, only relying on the external moisture of the friction surface, and no lubricating oil is exerted on the friction surface. Due to the lubricating effect in the worm gear, the friction between the worm wheel and the worm is large, the wear is large, and the heat is large. Contents of the invention [0003] In order to overcome the disadvantages of insufficient lubrication, large wear and serious heat generation in the existing worm gear, the invention provides a lubricated worm gear. [0004] The technical solution adopted by the present invention to solve the technical problem is: a lubricati...
