Abstract
A novel external spherical ball bearing with a concentric cover comprises an outer ring, an inner ring, steel balls, a retainer, sealing rings, check rings, a rivet, a concentric cover and a screw, wherein the inner ring is provided with a roller path and a concentric platform, and the concentric platform is provided with an elastic groove and a plurality of openings. The inner diameter of the concentric cover is matched with the outer diameter of the concentric platform of the inner ring, the concentric cover is provided with an opening, the left edge of the opening is provided with a through hole and a counter hole, and the right edge of the opening is provided with threads, and the opening realizes the fixed connection between the concentric platform and the concentric cover by the screw. The inner ring is sheathed in the outer ring, the inner side wall of the outer ring is provided with the roller path, the plurality of steel balls are fixed in the roller path between the inner and the outer ring by the retainer. The retainer is tightly fixed by the rivet. The sealing rings are arranged at two sides in the outer ring and seal the steel balls and retainer in the outer ring. The check rings are arranged at the outer sides of the sealing rings. A shaft passes through the inner ring and the concentric sleeve. The utility model does not damage the shaft, and can be assembled and disassembled rapidly, simply, conveniently and reliably.
Description
Technical field
The utility model relates to a kind of novel roller bearing units with concentric locking collar.
Background technique
A lot of roller bearing units are arranged in the market, and they select Cock screw, eccentric bushing or adapter sleeve to be mated the fastening effect that realizes with axle usually.But problem is, if select for use Cock screw to realize fastening effect, can exist like this to make axle produce eccentric defective easily, and when locking, Cock screw stays nonvolatil scar easily on axle; If select for use eccentric bushing to realize fastening effect, can exist the axle can only be toward the problem of direction rotation, when locking, Cock screw stays nonvolatil scar easily on axle; If select for use adapter sleeve to realize fastening effect, will there be the deficiency of installation and removal inconvenience like this, foul is access arrangement the cracking in the middle of adapter sleeve easily.
Summary of the invention
In order to remedy above-mentioned existing easy generation eccentric shaft, unidirectional rotation, on axle, stay permanent scar, to mount and dismount inconvenient defective, the utility model provides a kind of novel roller bearing units with concentric locking collar, it does not only produce infringement to axle, and can not produce the problem of eccentric shaft, unidirectional rotation, it can be quick, easy, installation and removal reliably, and can turn round on high rotating speed ground.
In order to achieve the above object, the utility model adopts following concrete technological scheme: the novel roller bearing units of band concentric locking collar, it mainly is made up of outer ring, inner ring, steel ball, retainer, seal ring, back-up ring, rivet, concentric locking collar, screw, its structure characteristic is, inner ring is provided with raceway, also be provided with the concentric platform concentric with internal diameter on the inner ring, platform is provided with elastic groove with one heart, also is provided with a plurality of openings on the platform with one heart; The concentric locking collar internal diameter matches with the concentric platform external diameter of inner ring, and concentric locking collar is provided with an opening, and the left side of opening is a through hole and a counterbore, and the right of opening is a screw thread, and this opening is realized being fastenedly connected of concentric locking collar and concentric platform by screw; The outer ring is placed in inner ring wherein, and the outer ring madial wall also is provided with raceway, and a plurality of steel balls are fixed in the raceway between outer ring and the inner ring by retainer; Retainer is realized fastening by rivet; Seal ring is arranged at the both sides of inside, outer ring, in so just steel ball and retainer being sealed in, prevents that foul from entering; Back-up ring is arranged at the outside of seal ring; Axle passes from inner ring and concentric locking collar.
Axle is packed into behind the inner ring, again concentric locking collar is packed on the concentric platform on the inner ring, tighten screw with wrench, concentric locking collar is shunk, therefore the endoporus of concentric locking collar diminishes, thereby concentric platform of inner ring and axle are riveted together tightly, so just can make brearing bore and axle with one heart, and can not damage the surface of axle.
The beneficial effects of the utility model are: it does not only produce infringement to axle, and can not produce the problem of eccentric shaft, unidirectional rotation, and it can quick, easy, installation and removal reliably.
The utility model is described in further detail below in conjunction with drawings and Examples.
