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

Abstract

The invention provides a cycloid reduction gearbox of an interlayer air cooling box zinc base alloy bearing support. The cycloid reduction gearbox of the interlayer air cooling box zinc base alloy bearing support comprises a box body, an input shaft, a transmission mechanism and an output shaft and is characterized in that an inner cylinder and a round end cover connecting piece are arranged in the box body, the inner cylinder is connected with the box body, the input end of a round end cover is in close fit with an inner hole of the input end of the box body, the round end cover is connected with the box body through an annular disc, an interlayer is formed by the inner wall of the box body, the inner cylinder and the outer wall of the round end cover connecting piece, the top and the side of the box body are provided with a ventilation window and a fan, the transmission mechanism comprises a cycloidal gear, a pin wheel housing, a pin and an eccentric bearing, a wear-resisting ring on the output shaft supports the interior of a zinc base alloy bearing, a sponge with a 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, the zinc base alloy bearing is arranged in a uniform load ring, and therefore a simple output shaft zinc base alloy bearing supporting structure is formed. The cycloid reduction gearbox has the technical advantages that the structure is simple, manufacturing cost is low, the air volume is adjusted, thermal power is close to mechanical power, the alloy bearing is reliably lubricated, bearing cost is lowered by 60% to 80%, and steel for the bearing can be saved by 50% to 70%.

Description

【Technical Field】 [0001] The present invention relates to the improvement of K-V-H mechanism (N type) less tooth difference technology in the field of general planetary technology, in particular to the improvement of cycloid gearbox, a kind of cycloid gearbox supported by zinc-base alloy bearing of sandwich air-cooled box. 【Background technique】 [0002] Universal planetary transmission mainly includes 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 shortcomings: [0004] (1) The output shaft is supported by rolling bearings, and the cost is much higher than that of sliding bearings, especially high-power and high-torque models: the basis is found in the "Design and Manufacturing of Involute Gear Planetary Transmission" Chapter 12 Cement Ball Mill Reducer Calculation Examples: [000...
