Abstract

The utility model relates to the improvement on a bearing, in particular to an improved rolling ball bearing. The improved rolling ball bearing consists of an inner ring, a ball group and an outer ring, and is characterized in that a plurality of connection screw holes are uniformly formed on the ring surface of the shaft shoulder of the inner ring; the shaft shoulder of the outer ring adopts a stepped structure, and a plurality of connection screw holes are uniformly formed on the ring surface of the lower shaft shoulder of the outer ring; and ball group is in retainer-free arrangement, and balls are filled in deep rolling paths of both the inner ring and the outer ring. The utility model solves the problem that bearings of some heavy equipment have insufficient load-bearing capacity, and is mainly used for bearing improvement.

Description

A kind of modified model rolling ball bearing

(1). technical field: the utility model relates to the transformation of bearing, is a kind of modified model rolling ball bearing.

(2). background technique: the employed special bearing of domestic some introducing equipment, because of the defective bearing in the design often is in the overload operation state, bearing shortening in working life is changed frequent; And domestic existing standard rolling bearing product can't satisfy the requirement on the equipment replacement type selecting performance, and the improvement of bearing products has been proposed new requirement.

(3). summary of the invention: the purpose of this utility model is exactly the problem that will solve the bearing load carrying capacity deficiency of some jumbo, and a kind of modified model rolling ball bearing is provided.

Concrete scheme of the present utility model is: a kind of modified model rolling ball bearing, and it has inner ring, ball set and outer ring; It is characterized in that: evenly be furnished with several on the inner ring shaft shoulder anchor ring and connect screw; The shaft shoulder stepped structure in outer ring evenly is furnished with several and connects screw on the shaft shoulder anchor ring under the outer ring; Ball set adopts no retainer arrangement mode, and ball completely is contained in the deep trouth raceway of inside and outside blowout patche.

The utility model is compared with existing standard bearing product, has the not available property of standard rolling bearing, is characterized in: be furnished with the connection screw on the inside and outside circle shaft shoulder of bearing, when having reduced overhaul of the equipments to the dismounting difficulty of bearing; Ball set adopts no retainer directly to adorn mode, and ball completely is contained on the inside and outside circle raceway of bearing, has improved the bearing capacity of bearing to greatest extent.

The utility model is installed on the existing equipment, logical operation test in a few years, and the performance index of modified model rolling ball bearing have satisfied the required requirement of equipment fully; Also improved five times than original-pack bearing the working life of bearing.
