Description

Technical Field

[0001] The utility model relates to the technical field of bearings, in particular to a roller bearing assembly. Background Art

[0002] Roller bearing assemblies are usually used in situations where heavy loads and impact loads are required, such as metallurgy, mining, ships, ports and cranes. They reduce friction resistance and transmit loads through rolling friction, have a low friction coefficient and high efficiency, and are therefore widely used in a variety of equipment that require high precision, high efficiency and heavy load capacity.

[0003] Most of the current roller bearing assemblies usually need to match the size when installed on the shaft. If the size of the shaft is slightly smaller than the size of the roller bearing assembly, the shaft will easily shake, resulting in poor overall stability. This need for size matching makes the use environment of the roller bearing assembly relatively single and its practicality is low. Utility Model Content

[0010] The utility model provides a roller bearing assembly, which has the following beneficial effects:

[0011] The utility model drives the driven inclined block to move in the adjusting groove by rotating the screw rod, so that the driven inclined block contacts the pressing inclined block, and generates an extrusion force on the pressing inclined block under the action of the screw rod. Under the action of the extrusion force, the elastic fixing plate is bent and deformed, so that the surface of the elastic fixing plate is in close contact with the outer surface of the shaft to be installed, thereby realizing rapid fixation of the shaft and the bearing, and enabling the bearing to be fixed to a shaft slightly smaller than its size, thereby improving the use range and practicality of the bearing, and having a simple structure and convenient fixation.

[0019] like Figure 3 and Figure 4 As shown, the outer surface of the inner ring 1 and the inner surface of the outer ring 9 are both provided with limit grooves 14, and a plurality of balls 7 are rollingly connected inside the two limit grooves 14. By setting the limit grooves 14, the moving trajectory of the balls 7 can be positioned, and by setting the balls 7, the friction force generated when the inner ring 1 and the outer ring 9 rotate can be reduced.

[0020] like Figure 2 and Figure 4 As shown, the outer surfaces of multiple balls 7 are rollingly connected to a stabilizing frame 8, and both ends of the stabilizing frame 8 are slidably connected to a positioning ring 11. One end of the two positioning rings 11 is respectively fixedly connected to the two ends of the outer ring 9.

[0023] The utility model provides a roller bearing assembly, and the specific working principle is as follows:

[0024] When the bearing and the shaft need to be installed and fixed, the staff moves the bearing assembly to the position where it needs to be fixed, and then provides a screwdriver to rotate the four screw rods 3 in turn. During the rotation of the screw rods 3, the driven bevel block 4 is driven to move inside the adjustment groove 2, so that the driven bevel block 4 is in contact with the pressing bevel block 6, and under the action of the thrust of the screw rod 3 on the driven bevel block 4, an extrusion pressure is generated on the pressing bevel block 6, and under the action of the extrusion pressure, the elastic fixing plate 5 is bent and deformed, so that the surface of the elastic fixing plate 5 is in close contact with the surface of the shaft to be installed, and the shaft and the bearing are quickly fixed. When the size of the shaft is slightly smaller than the size of the bearing assembly, it can still be fixed.
