Problems solved by technology

But these bearings are all special bearings, and the size of the bearings is 4×6mm, which is not suitable for use on the cam water pump of the water jet loom
However, the traditional roller bearing used in the cam water pump of the water jet loom has problems in its structural design. The two rows of rollers are close together, the friction resistance is large, and it is not easy to inject oil. Under long-term operation, the lubrication will fail and it will easily generate high temperature. And then burned out, the service life is shorter

Embodiment Construction

[0009] The present invention is described in further detail now in conjunction with accompanying drawing. These drawings are all simplified schematic diagrams, which only illustrate the basic structure of the present invention in a schematic manner, so they only show the configurations related to the present invention.

[0010] Such as figure 1 As shown, a supporting roller bearing includes an outer ring 1, an inner ring 2 and two rows of rollers 3, and the two rows of rollers 3 are installed between the outer ring 1 and the inner ring 2, and the two rows of rollers 3 are separated by Distance, the inner ring 2 is provided with an oil injection hole 4, which corresponds to the space between two rows of rollers 3, the length of the roller 3 is 4mm, the outer diameter of the roller 3 is 4mm, one side of the inner ring 2 An inner retaining ring 5 for positioning the roller 3 is provided on one side, and the other side of the inner ring 2 has a rib 21 protruding toward the axis o...

Abstract

The invention relates to a supporting idler wheel bearing which comprises an outer ring, an inner ring and two rows of rollers, wherein the two rows of rollers are arranged between the inner ring and the outer ring and are separated from each other with certain distance; the inner ring is provided with an oil injection hole and corresponds to the interval space between the two rows of rollers; and the length of the roller is 4mm and the outer diameter of the roller is 4mm. The supporting idler wheel bearing has an unique structure; as the two rows of rollers are arranged at intervals, the frictional resistance is avoided; as the size of the roller is reduced, the distance among the rollers can be enlarged, and as the inner ring is provided with the oil injection hole, oil can be injected and stored conveniently, the lubrication effect is good, the service life of the bearing is prolonged by one time compared with a traditional bearing; and the supporting idler wheel bearing is mainly applied on a water pump of a water-jet loom cam.

Description

technical field [0001] The invention relates to a roller bearing, in particular to a supporting roller bearing used in the field of textile machinery. Background technique [0002] Imported supporting roller bearings are widely used in mechanical and electrical special bearings, rolling mill special bearings, metallurgy special bearings, automobile special bearings, ship special bearings, papermaking special bearings, industrial fan special bearings, industrial pump special bearings, and motor special bearings due to their advanced structural design. and many other fields. But these bearings are all special bearings, and the size of the bearings is 4×6mm, which is not suitable for use on the cam water pump of the water jet loom. However, the traditional roller bearing used in the cam water pump of the water jet loom has problems in its structural design. The two rows of rollers are close together, the friction resistance is large, and it is not easy to inject oil. Under lon...
