Description

Spherical roller bearing outer guide solid cage for vibrating machinery

technical field

The utility model relates to a cage, in particular to a spherical roller bearing external guide entity cage for vibration machinery.

Background technique

In the application of vibrating machinery, the early failure of the cage accounts for a large proportion of the early failure of the bearing. Because in the application of vibrating machinery, rotational acceleration and linear acceleration are generated between the rollers of the bearing and the cage, the cage needs to bear the rotational load caused by the rotation of the unloaded roller when bearing the rotational acceleration, and needs to bear the unloading when bearing the linear load Roller knock load. The spherical roller bearings used in this working condition need to withstand much higher acceleration than normal standard bearings. This also greatly increases the design requirements of the bearing cage.

Utility model content

In order to solve the above technical problems, the purpose of this utility model is to propose a spherical roller bearing external guide solid cage for vibration machinery.

The utility model adopts following technical scheme for accomplishing above-mentioned invention task:

A spherical roller bearing outer guide solid cage for vibration machinery, the spherical roller bearing outer guide solid cage includes two outer guide double-half solid cages arranged oppositely, and the two outer guide double-half solid cages There is a gap between the solid cages; there are multiple oil grooves I distributed along the circumference on the contacting end faces of the two outer guiding double semi-solid cages, and there are multiple oil grooves I distributed along the circumference perpendicular to the contacting end faces of the two outer guiding double semi-solid cages. There are multiple oil grooves II distributed along the circumference on the outer spherical surface; there are slopes on the outer circular surface of the contacting end faces of the two outer guiding double semi-solid cages to increase the lubrication effect; the outer guiding solid cage The radial surface is a spherical arc surface, the minimum diameter of the outer diameter surface of the outer guide solid cage is a plane, and the maximum length H of the outer diameter surface of the outer guide solid cage is smaller than the inner diameter of the rib of the outer ring of the bearing.

The utility model proposes a self-aligning roller bearing external guide entity cage for vibrating machinery. The above-mentioned technical scheme is adopted to better solve the problem caused by the self-aligning roller bearing cage for vibrating machinery when it is subjected to rotational acceleration and linear acceleration. The impact of the load on the cage prolongs the service life of the cage, thereby improving the life of the spherical roller bearings used in vibrating machinery.

Detailed ways

As shown in Figure 1, and with reference to Figures 2 and 3, a spherical roller bearing outer guide solid cage for vibration machinery, the spherical roller bearing outer guide solid cage includes two oppositely arranged outer guide solid cages Guide the double semi-solid cage 3, and there is a gap between the two outer guide double semi-solid cages 3; there are multiple oil grooves I5 distributed along the circumference on the contacting end faces of the two outer guide double semi-solid cages, On the outer spherical surface perpendicular to the contacting end faces of the two outer guiding double semi-solid cages, there are multiple oil grooves II6 distributed along the circumference; In order to increase the lubricating effect of the slope 4, the width h angle α of the slope 4 is determined according to the size of the cage; the outer diameter surface of the outer guide double semi-solid cage is a spherical arc surface, combined with Figure 3, the outer guide double The minimum diameter of the outer diameter surface of the semi-solid cage is a plane, and the maximum length H of the outer diameter surface of the outer-guided double semi-solid cage is less than the inner diameter of the rib of the outer ring of the bearing. The specific method is to cut the diameter direction of the outer diameter surface of the cage. Top, to ensure that the H value after the top is cut is smaller than the inner diameter of the bearing outer ring rib, in order to facilitate the assembly of the outer guide double semi-solid cage.

When the self-aligning roller bearing outer guide cage is used, it is guided by the bearing outer raceway. The outer diameter of the cage is a spherical arc surface. After assembly, the gap between the end faces of the two outer guide double semi-solid cages is 2s. The diameter SR is the diameter of the outer raceway of the bearing minus twice the guide clearance, and the center of the ball is at the symmetrical center of the bearing, so the distance between the center of the ball and the end face of the cage is s.
