detailed description

The utility model will be described in further detail below in conjunction with the embodiments provided by the accompanying drawings.

Refer to Figure 1-2

A cylindrical roller bearing with a flange, comprising an outer ring 1, an inner ring 2, a rolling body 3 arranged between the outer ring 1 and the inner ring 2, and a cage 4 for the rolling body 3, the outer ring 1 A flange 5 is provided on the end face of the roller, and the rolling element 3 is a cylindrical roller, and its axial sectional surface is square.

By arranging the flange 5, the interference fit installation method of the conventional outer ring 1 is avoided, thereby increasing the outer diameter of the bearing, increasing the internal space of the bearing, and thereby improving the bearing capacity of the bearing. Cooperating with square cylindrical rollers, it meets the high-speed and high-load performance. Under the high-speed performance requirements, the square structure runs smoothly, which can better meet the use requirements.

Preferably, the end edges of the cylindrical rollers are chamfered. The chamfer is formed by fine grinding, and the smoothness is improved by using the chamfer, and the contact between the end edge of the roller and the outer ring 1 and inner ring 2 is reduced. In addition, during the rolling process of the rolling element 3, the gap formed by the chamfering can allow the grease to pass through, which has a certain grease storage effect.

Specifically, in order to meet the high-speed performance requirements, the outer ring 1 is made of stainless steel, and the forming method is a forging, which is tempered at a high temperature. The cage 4 is supported by an alloy steel material, and the forming method is a forging. Wherein the guiding method of the cage 4 is external guiding.

In order to increase the stability of the connection of the flange 5 , the flange 5 has at least three connection ends 6 which are evenly distributed along the circumference of the outer ring 1 .

Further, the connection end 6 has a through hole for passing through a screw, and the side surface of the connection end 6 away from the outer ring 1 is provided with a circular array of embossments 7 with the center of the through hole as the center point.

The arrangement of the embossed lines 7 can increase the frictional force at the joints of the flanges 5 . Due to the increase in the frictional force, the relative vibration displacement between the joints of the flanges 5 can be weakened, thereby reducing the probability of bolt loosening.

More specifically, the embossed lines 7 are strip-shaped and form a reflective structure.

The radially distributed embosses 7 can further increase the frictional force, and because they are strip-shaped and distributed in the circumferential direction, they can sufficiently hinder relative displacements in all directions and improve the stability in the assembled state.

Preferably, the edge of the cage 4 corresponding to the side of the inner ring 2 is provided with a chamfer. The setting of the chamfer helps to reduce the weight of the cage 4, thereby adapting to the working condition of high-speed rotation, and also helps to improve the circulation of lubricating grease.

As an extended improvement of this solution, the other end of the outer ring 1 corresponding to the flange 5 is provided with a bump 8 .

In a special environment, multiple bearings may be installed at the same time. The set protrusion 8 can be installed in conjunction with the adjacent bearing, and a corresponding groove is provided on the adjacent bearing outer ring 1. When both are installed at the same time , the protrusion 8 can be embedded in the groove, the problem of slipping of the outer ring 1 of the two can be reduced, the stability of the use process can be improved, and the service life of the bearing can be improved.

The above descriptions are only preferred implementations of the present utility model, and the protection scope of the present utility model is not limited to the above-mentioned embodiments, and all technical solutions under the idea of the present utility model all belong to the protection scope of the present utility model. It should be pointed out that for those skilled in the art, some improvements and modifications without departing from the principle of the utility model should also be regarded as the protection scope of the utility model.
