Floating-type gear transmission device

Abstract

The invention discloses a floating-type gear transmission device which comprises a base. The base is provided with two bearing pedestals, and bearings are installed in the corresponding bearing pedestals. A supporting shaft is installed in the bearings, and two shaft shoulders are arranged in the middle of the supporting shaft. A first gear is arranged on the supporting shaft and located between the two shaft shoulders, and inner spherical tiles are arranged on the supporting shaft and located at the two outer sides of the shaft shoulders correspondingly. A second gear is arranged at the outer side of the first gear. The inner side of the second gear is engaged with the first gear. The outer sides of the inner spherical tiles are provided with outer spherical tiles matched with the inner spherical tiles separately. The two sides of the second gear are each fixedly connected with a transparent cover, and a distance is kept between the inner side of the middle part of each transparent cover and the supporting shaft. Each transparent cover comprises a limiting part, and the limiting parts are connected with the corresponding outer spherical tiles. According to the floating-type gear transmission device, the spherical tile structure is adopted, the purpose that the gears can swing along with swinging of driven gears can be achieved, and the tooth surface combining condition is effectively improved; and the spherical tiles are simple in structure, the gear size cannot be greatly increased, cost is low, the second gear and the supporting shaft are in gear connection, and the supporting shaft cannot swing.

Description

technical field [0001] The invention relates to the field of transmission devices, in particular to a floating gear transmission device. Background technique [0002] Gear transmission is widely used in various mechanical equipment, especially in asymmetric gear pairs such as tube mills and rotary kilns. Due to the bending of the equipment, the contact coefficient of the tooth surface of the gear is low, and the wear is not uniform, which also limits the transmission. ability. [0003] In the existing equipment, there are generally two ways to deal with it. The first one: most of them are installed in parallel, and generally do not deal with the non-parallel joint surface caused by the bending of the equipment during operation. In order to improve the service life, Generally, the strength of the gear is improved, the degree of surplus is increased, and the opposite side is used after a certain period of wear. The second method is to add a rubber pad to the gear base to i...

Problems solved by technology

The second method: add a rubber pad to the gear base to improve the contact of the tooth surface by the deformation of the rubber pad, but this form causes the pinion shaft to swing, and the design requirements for the base are relatively high and the design is complicated
