The effect of the NSK bearing cooperation is that the stop ring and the rotating ring of the NSK bearing are fixed from the stop of the device (usually the bearing seat) and some of the rotation (usually the shaft); then the load is transmitted under the rotating state. The basic task of limiting the movement system relative to the orientation of the stopping system.
In the shaft and in the NSK bearing seat; the radial and tangential positioning is completed by the tight cooperation of the NSK bearing ring; the axial positioning is selected as the tight cooperation in a small number of cases, usually the axial limit parts are used; Covers and retaining rings limit the axial orientation within the clearance range.
The application method of NSK bearing is very messy; some rolling bearings are used in cooperation; this common knowledge is usually known to technicians; we usually don't know the people; let's analyze the application of this rolling bearing cooperation for us. Demand; also knows about NSK Bearings in the future.
The professor pointed out that the selection of cooperation should focus on the following four points:
(1) The circumferential surface of the NSK bearing ring should have excellent support and uniform force; to reduce deformation; and fully utilize the bearing capacity of the bearing.
(2) The ferrule cannot slide in the direction of the tangential direction in its cooperation appearance; otherwise, the cooperation surface will be damaged.
(3) It is necessary to be able to change the length of the shaft and the bearing housing hole with the NSK bearing at the free end; that is, it is necessary to have the ability to swim in a certain range with the customary axial orientation.
(4) It is necessary to pay attention to making the NSK bearing device and disassembly simple; saving labor and time.
