Abstract
The invention relates to a precise escalator bearing. The precise escalator bearing comprises an inner ring and an outer ring, wherein a holder is arranged between the inner ring and the outer ring; rolling bodies are uniformly distributed in the holder; sealing rings are arranged at the two sides of each rolling body. The precise escalator bearing is characterized in that the two ends of each sealing ring are respectively arranged in a first dustproof slot in the outer side surface of the inner ring and a second dustproof slot in the inner surface of the outer ring; the first dustproof slot and the second dustproof slot are stepped slots; and outer side walls of the first dustproof slot and the second dustproof slot are inclined surfaces which are inclined towards the inner side. The height of the outer sides of the first dustproof slot and the second dustproof slot is greater than that of the inner sides of the first dustproof slot and the second dustproof slot. The inner ring protrudes by 0.5mm at two axial ends relative to the outer ring. The outer circle chamfer angle of the outer ring is 2.0 +/-0.02mm in the radial direction, and 1.0+/-0.01mm in the axial direction. The diameter of the inner hole of the inner ring is 5.1+/-0.3mm. The precise escalator bearing is good in sealing performance, so that the service life of the bearing is prolonged, and the utilization rate of the product is increased.
Description
Technical field
The present invention relates to a kind of bearing, especially a kind of escalator precision bearing, belongs to micro precision bearing field.
Background technique
For the bearing of escalator primarily of compositions such as outer ring, inner ring, retainer, rolling element, seal ring, lubricating grease.Between outer ring and inner ring, rolling element is installed, with retainer location, the even separation roller of retainer and maintenance rolling element proper exercise; Seal ring plays dust-proof and effect that is that prevent lubricating grease from leaking outside, and lubricating grease plays lubrication and forms the effects such as oil film.On the rotor that this bearing assemble rotates at high temperature and high speed, the bearing of High Rotation Speed can produce very large heat, bearing can be made like this to occur stuck, cause bearing failure, thus this just to the sealing of product and lubricating grease requirement very strict.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art, provide a kind of escalator precision bearing, favorable sealing property, improve the working life of bearing, improve the utilization ratio of product.
According to technological scheme provided by the invention, a kind of escalator precision bearing, comprises inner ring and outer ring, between inner ring and outer ring, arranges retainer, be uniformly distributed rolling element in retainer, arranges seal ring in rolling element both sides; Feature is: the two ends of described seal ring are arranged in the first dustproof groove of inner ring outer side surface and the second dustproof groove of outer ring inner side surface respectively, first dustproof groove and the second dustproof groove are stepped slot, and the outer side wall of the first dustproof groove and the second dustproof groove is the inclined-plane tilted to the inside.
Further, the height outside described first dustproof groove, the second dustproof groove is lower than the height of inner side.
Further, described inner ring gives prominence to 0.5mm than outer ring respectively at axial two ends.
Further, the outer rounded corner radial direction of described outer ring is 2.0 ± 0.02mm, is axially 1.0 ± 0.01mm.
Described inner ring diameter of bore is 5.1 ± 0.3mm.
The present invention compared with prior art has the following advantages: (1) sealing structure of the present invention performance is better, adopt contact sealing ring, improve the sealability of bearing, lubricating grease uses low-noise lubricating grease, and the abrasion resistance of this lubricating grease lubricating grease under high voltage load, corrosion resistance and water resistance are better; (2) the present invention can improve the working life of bearing, improves the utilization ratio of product.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Embodiment
Below in conjunction with concrete accompanying drawing, the invention will be further described.
As shown in Figure 1: described escalator precision bearing comprises inner ring 1, outer ring 2, rolling element 3, retainer 4, seal ring 5, first dustproof groove 6, second dustproof groove 7 etc.
As shown in Figure 1, the present invention includes inner ring 1 and outer ring 2, retainer 4 is set between inner ring 1 and outer ring 2, rolling element 3 is uniformly distributed in retainer 4, in rolling element 3 both sides, seal ring 5 is set, the two ends of seal ring 5 are arranged in the first dustproof groove 6 of inner ring 1 outer side surface and the second dustproof groove 7 of outer ring 2 inner side surface respectively, first dustproof groove 6 and the second dustproof groove 7 are stepped slot (i.e. the first dustproof groove 6, height outside second dustproof groove 7 is lower than the height of inner side), the outer side wall of the first dustproof groove 6 and the second dustproof groove 7 is the inclined-plane tilted to the inside, effectively can play waterproof, etch-proof effect, meet in escalator and use in complex environment,
Described inner ring 1 gives prominence to 0.5mm than outer ring 2 respectively at axial two ends, and mainly for meeting the use of handrail elevator, handrail elevator adopts radial transmission, and traction sheave diameter is little, uses Steel Belt Transmission;
The outer rounded corner radial direction of described outer ring 2 is 2.0 ± 0.02mm, is axially 1.0 ± 0.01mm; Described inner ring 1 diameter of bore is 5.1 ± 0.3mm; Inner ring adopts V-shaped groove structural design, effectively plays waterproof, etch-proof effect, meets in escalator and use in complex environment.
