Self-aligning roller

Abstract

The invention discloses an automatic center adjusting support wheel which comprises a support wheel rib. The support wheel rib is divided into an inner ball rib and an outer ball rib. The inner ball rib is sleeved on the outer circumferential face of the outer ball rib, and the inner ball rib and the outer ball rib are in clearance fit. The outer circumferential face of the outer ball rib is the spherical face, and the spherical center point of the outer ball rib is coincident with the center point of the inner ball rib and the outer ball rib. A roller path is arranged on the inner wall of the inner spherical face, and the roller path is wedged with the spherical face shape of the outer ball rib. The inner ball rib is capable of rotating through 360 degrees relative to the outer ball rib. A limit member is arranged between the inner ball rib and the outer ball rib, and the limit member can limit the inner ball rib to be located at the rotating position of the outer ball rib. The support wheel rib is divided into the inner ball rib and the outer ball rib. Due to the fact that the inner ball rib can rotate through 360 degrees, the inner ball rib can rotate correspondingly with a furnace body when the furnace body deviates in the rotation process. Therefore, the support wheel and a rolling ring are completely contacted in the axial direction, and the aims of adjusting and protecting the support wheel initiatively can be achieved.

Description

technical field [0001] The invention relates to the technical field of calciner support, in particular to a support device for a chemical soda ash calciner, in particular to an automatic self-aligning supporting wheel. Background technique [0002] The soda ash calciner is a large rotary cylinder equipment with double support points. This kind of rotary cylinder with heavy load and large impact load supports the entire weight of the rotating part of the furnace body through the supporting wheels, so that the furnace body and the rolling ring on the furnace body can rotate smoothly on the supporting wheels. Because the furnace body has good rigidity, large load, and high speed, and the performance of the support wheel is weaker in the above aspects, it must be ensured that the contact width between the rolling ring on the furnace body and the surface of the support wheel is ≥ 75%. There are high requirements for the installation accuracy of the supporting roller. Since the ...

Problems solved by technology

[0005] From the description of the above technical solution, it can be seen that although the existing supporting roller adopts a two-layer structure, only the supporting roller sleeve 4 needs to be replaced when the supporting roller is damaged, which does reduce the overall maintenance cost of the supporting roller to a certain extent. But it still doesn't solve the problem that the supporting roller is in a passive damaged state

At the same time, the existing supporting rollers still require operators to carry out higher frequency monitoring

Therefore, the supporting rollers provided in the prior art cannot effectively solve the problem of high loss of supporting rollers and rolling rings.
