Abstract

The gear transmission mechanism using the flexible belt as the meshing medium relates to the gear transmission mechanism. Aiming at the prior art metal gear skeleton and the gear composed of the polymer oil-containing alloy material cladding compounded or pasted on both sides of the gear, it has the advantages of good self-lubricating performance, etc. The layers are easy to peel off, and the manufacturing cost is high. The plane-tooth single-enveloping toroidal worm gear transmission pair covered with flexible materials on the worm gear tooth surface still has the above shortcomings, and a gear transmission mechanism with flexible belts as meshing medium is proposed. The technical solution adopted is that a movable closed flexible belt (3) is set on the gear teeth of one of the gears, retaining rings (5) and gear screws ( 7) Connect. It has the characteristics of reducing tooth surface friction and noise; it can be lubricated by oil or water, without environmental pollution; the elastic deformation of the flexible belt can automatically adjust the shape and position error, and the cost can be reduced when changing the belt without changing the gear.

Description

1. Technical Field

[0001] The invention relates to a gear transmission mechanism, in particular a gear transmission mechanism using a flexible belt as a meshing medium. 2. Background technology

[0002] Gear is a basic part of mechanical transmission widely used in industry, agriculture, national defense, science and technology and other economic sectors. In the current gear industry, from the perspective of materials, gears are divided into two categories: metal gears and non-metal gears. The metal gear pair is a high pair of "high modulus (metal)-high modulus (metal)". It has the outstanding advantages of high speed and large carrying capacity, but it has vibration and noise. It can only be lubricated with oil lubricant Therefore, it is easy to pollute the environment; and the hard-tooth surface gear needs to be quenched and ground, and the process is complicated; the required processing accuracy is high, and the production cost is high. Non-metallic gear pairs belong to the hi...
