Embodiment Construction

[0031] Hereinafter, specific embodiments of the present invention will be described in detail with reference to the accompanying drawings.

[0032] refer to figure 1 , figure 2 , image 3 and Figure 4 , The bearing limiting system provided by the specific embodiment of the present invention is applied to a long-axis bearing, the long axis of which is tapered, and the shaft diameter of the section farther from the load end is smaller. In the present invention, the end farther away from the load end and with a smaller shaft diameter is defined as the far end; the end closer to the load end and with a larger shaft diameter is defined as the proximal end. At a certain distance from the bearing installation part, a raised stopper or a raised retaining ring (that is, a limit protrusion 1) is designed, and the outer diameter of the stopper or retaining ring is not larger than the inner diameter of the bearing inner ring 2, so as to ensure that the inner ring of the bearing is no...

Abstract

The invention provides a bearing limiting system, which comprises a limiting protrusion (1) integrally formed with the shaft, a bearing inner ring (2) and a force transmission part (3), the force transmission part (3 ) is arranged between the limiting protrusion (1) and the bearing inner ring (2), and the inner diameter of the bearing inner ring (2) is larger than the outer diameter of the limiting protrusion (1). The invention also provides a bearing position limiting method. The bearing limiting system provided by the present invention is easy to install, and can effectively limit the inner ring of the bearing without affecting the strength of the shaft and the assembly and disassembly of the bearing, and is especially suitable for long-axis bearings.

Description

technical field [0001] The application relates to a bearing limiting system and a limiting method. Background technique [0002] The bearing is a component that fixes and reduces the friction coefficient of the load during the mechanical transmission process. Its main function is to support the mechanical rotating body to reduce the mechanical load friction coefficient of the equipment during the transmission process. According to the different friction properties of moving elements, bearings can be divided into two types: rolling bearings and sliding bearings. [0003] Bearing is an important basic component of various mechanical equipment, its precision, performance, life and reliability play a decisive role in the accuracy, performance, life and reliability of the main engine. Therefore, after the bearing is installed in place, it is necessary to take measures to limit the position of the bearing, so as to prevent the displacement of the bearing, which will cause the per...
