Reduction box with small tooth difference for interlayer water-cooling tank zinc-based alloy bearings

Abstract

The invention provides a reduction box with small tooth difference for interlayer water-cooling tank zinc-based alloy bearings. The reduction box comprises a tank body, an input shaft, a transmission mechanism and an output shaft, and is characterized in that an inner cylinder and circular end cover connecting part is arranged in the tank body, an inner cylinder is connected with the tank body, the input end of a circular end cover is in close fit with an inner hole of the input end of the tank body, the circular end cover is connected with the tank body through a circular ring plate, an interlayer is formed between the inner wall of the tank body and the outer wall of the inner cylinder and circular end cover connecting part, and a water inlet valve and a water drain valve are arranged on the top and the lateral of the tank body; the transmission mechanism comprises a planet wheel, an inner tooth ring and an eccentric bearing, a wearing ring on the output shaft is supported in one zinc-based alloy bearing, a sponge with the T-shaped section is arranged in the output shaft, an oil storage cavity Q is formed by the sponge in the output shaft and a shaft hole of the output shaft, the other zinc-based alloy bearing is arranged in a uniform load ring, and an output shaft zinc-based alloy bearing simple support structure is formed. The reduction box has the technical advantages that the structure is simple and constructing cost is low; water flow is adjusted so that thermal power can approach to mechanical power; the alloy bearings are reliable in lubrication, cost can be lowered by 60-80 percent, and steel for the bearings can be saved by 50-70 percent.

Description

【Technical field】 [0001] The invention relates to the improvement of the K-V-H mechanism (N type) less tooth difference technology in the field of general planetary technology, in particular to the improvement of a cycloidal reduction box, a kind of small tooth difference reduction box supported by a zinc-based alloy bearing in a sandwich water-cooled box. 【Background technique】 [0002] The general planetary transmission mainly includes two types: 2K-H negative sign mechanism (NGW type) and K-V-H mechanism (N type), and K-V-H mechanism (N type) includes cycloid and involute with less tooth difference. [0003] The study found that the existing universal planetary transmission technology has two deficiencies: [0004] (1) The output shaft is supported by rolling bearings, and the cost is much higher than that of sliding bearings, especially for high-power and high-torque models: the basis for this can be found in "Design and Manufacture of Involute Gear Planetary Transmissio...

AI Technical Summary

Problems solved by technology

[0018] Purpose of the present invention: to solve the prior art (1) the output shaft is supported by rolling bearings, and the cost is much higher than that of sliding bearings, especially for high-power and high-torque models; (2) the gearbox itself does not have a heat dissipation function, so the thermal power is low defect
