Embodiment Construction

[0020] The present invention will be further described in conjunction with specific embodiment now. These drawings are simplified schematic diagrams only to illustrate the basic structure of the present invention in a schematic way, so they only show the components relevant to the present invention.

[0021] Such as Figure 1 to Figure 6 As shown, a cylindrical roller bearing suitable for a long shaft includes an outer ring 1 and an inner ring 2, the inner ring 2 is arranged inside the outer ring 1, a raceway is formed between the outer wall of the inner ring 2 and the inner wall of the outer ring 1, and the rolling A number of cylindrical rollers 3 are arranged in the track. In order to improve the stability of the movement of the cylindrical roller 3, a cage is arranged in the raceway, and each cylindrical roller is arranged on the cage.

[0022] The outer surface of the raceway inner ring 2 forms a circle of convex outer surface 21, the raceway forms a circle of rolling g...

Abstract

The invention relates to a cylindrical roller bearing suitable for a long shaft. The cylindrical roller bearing comprises an outer ring and an inner ring, wherein the inner ring is arranged in the outer ring; a rolling way is formed between the outer wall of the inner ring and the inner wall of the outer ring; multiple cylindrical rollers are arranged in the rolling way; the rolling way is provided with a lap of outer curved surface outwards projected on the outer ring surface of the inner ring, and is provided with a lap of rolling groove on the inner ring surface of the outer ring; the bottom surface of the rolling groove is a lap of inner curved surface outwards projected; and the cylindrical rollers are positioned between the outer curved surface and the inner curved surface. The cylindrical roller bearing has 2-3 times of misalignment adaptability, can adapt to the long shaft, is high in flexibility, can bear different shaft degrees and flexibilities, can enable the inner ring and outer ring to be inclined by 8 degrees, and can satisfy the thermal expansion displacement demands of a free end of the long shaft.

Description

technical field [0001] The invention relates to a cylindrical roller bearing suitable for long shafts. Background technique [0002] In the metallurgical industry, continuous casting machines are needed. Due to the relatively long rolls, there will be a certain curvature of the shaft when it rotates. In the past, ordinary cylindrical roller bearings can only withstand a deflection error of 2.5′, so that the long axis lies in the normal bearing. When it is easy to damage the inner and outer rings of the bearing. [0003] And because the long shaft is long, ordinary bearings are set at both ends of the long shaft to support the long shaft. The bearing at one end of the long shaft is the positioning end, and the bearing at the other end of the long shaft is the movable end. As the long shaft heats up and expands, the long shaft The movable end of the bearing needs to be able to move freely in the axial direction, but the previous bearings cannot meet it.
