Slewing bearing for low-noise anti-invasion dust removing equipment

Abstract

The invention discloses a slewing bearing for low-noise anti-invasion dust removing equipment. The slewing bearing for the low-noise anti-invasion dust removing equipment comprises an outer ring, an inner ring and steel balls, wherein a rollaway nest is formed between the outer ring and the inner ring; the steel balls are uniformly distributed inside the rollaway nest; wedged sealing strips are arranged on the top and at the bottom of a space between the outer ring and the inner ring; two V-shaped sealing strips are arranged between two wedged sealing strips; the two V-shaped sealing strips are symmetrically distributed relative to the steel balls; outer ring mounting holes are formed in the outer ring; elastic pins are arranged inside the outer ring mounting holes; outer ring positioningseam allowances are formed in the side edge of the outer ring. Compared with the prior art, the slewing bearing for the low-noise anti-invasion dust removing equipment, provided by the invention, hasthe advantages as follows: due to adhesion of the end surface of the outer ring to a large surface of equipment component, h8 high-precision fitting and elastic pin connection, high-precision rigid connection and flexible transmission greatly reduce noises during equipment operation; meanwhile, through mounting and use of the wedged sealing strips and the V-shaped sealing strips, external dust invasion and internal grease overflowing are effectively prevented, so that a slewing bearing product has a smooth working condition during the operation and the service life of the slewing bearing product is prolonged.

Description

technical field [0001] The invention relates to the field of slewing bearings, in particular to a slewing bearing for low-noise and anti-invasion dust removal equipment. Background technique [0002] Slewing ring products are widely used in modern industry and are called "joints of machines". They are necessary for machines that need to perform relative rotational motion between two objects and at the same time bear axial force, radial force, and overturning moment. important transmission parts. With the rapid development of the machinery industry, slewing bearings have been widely used in marine equipment, engineering machinery, light industrial machinery, metallurgical machinery, medical machinery, industrial machinery and other industries. [0003] The structure type and transmission connection method of the slewing bearing products used in dust removal equipment determine the use status and service life of this type of slewing bearing products. The traditional slewing b...

Problems solved by technology

[0003] The structure type and transmission connection method of the slewing bearing products used in dust removal equipment determine the use status and service life of this type of slewing bearing products. The traditional slewing bearings are noisy during use and have low stability. It will be contaminated with more dust, and the dust will easily enter the raceway, which will affect the service life of the slewing bearing
