Abstract

The utility model relates to a bearing provided with double rows of rollers. The bearing comprises the double rows of the rollers and inner rings, wherein mounting sleeves are arranged on the outer surfaces of the rollers; inner clamping springs clamped with the mounting sleeves are mounted at two ends of each roller; and space rings are arranged between the inner clamping springs and the rollers. The bearing provided with the double rows of the rollers has the benefits as follows: the mounting sleeves are arranged, so that the bearing can be protected; and the usage effect of the bearing can be improved, the service life of the bearing is prolonged, requirements of various working environments are met, and the usage range of the bearing is enlarged.

Description

Double-row roller bearing
Technical field
The utility model relates to a kind of double-row roller bearing.
Background technique
In traditional bearing installing area, bearing mounting type is all directly bearing to be arranged between rotor and fixed block, between bearing and rotor, bearing and fixed block, all can only rely on extruding to be connected, mutual annexation is interference fit completely, corrosion for a long time, affects the mounting or dismounting of bearing then, or excessive wear, generation is skidded, and affects the transmission performance of bearing.Meanwhile, outside bearing is exposed to for a long time, lubricant oil easily volatilizees; also be easily subject to the pollution of foreign matter; for improving using effect and the working life of bearing, need to carry out long-term oil lubricating and regular bearing cleaning to bearing, the shortcoming of existing bearing is that bearing can not get protection.
Model utility content
The technical problems to be solved in the utility model is: based on the problems referred to above, provide a kind of double-row roller bearing.
The utility model solves the technological scheme that its technical problem adopts: a kind of double-row roller bearing, comprise biserial roller and inner ring, roller outer surface is provided with installation sleeve, and the two end part of roller are all provided with the interior jump ring with installation sleeve clamping, between interior jump ring and roller, are provided with spacer ring.
Further, the material of installation sleeve is polypropylene.
The beneficial effects of the utility model are: installation sleeve can be protected bearing, improve using effect and the working life of bearing, meet the demand of various working environments, expand the using scope of bearing.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the utility model is further illustrated.
Fig. 1 is structural representation of the present utility model.
Wherein: 1. roller, 2. inner ring, 3. installation sleeve, 4. interior jump ring, 5. spacer ring.
Embodiment
