Non-Standard Bearings Limited movement system
Application of non - standard bearings
The bearing mating function is such that the stationary ring and the rotating ring of the bearing are respectively engaged with the stationary part (usually the bearing seat) of the mounting part and the rotating part (usually the shaft), so as to realize the transfer of the load and the limited movement in the rotating state The basic task of the system relative to the still system location. In the shaft and the bearing seat, the rolling bearing in the radial, axial and tangential direction of the three directions to fix its position. Radial and tangential positioning is achieved by tight fitting of the bearing rings. Axial positioning is only tightly used in a few cases. Axial limit parts, such as end caps and retainers, are generally used to limit the axial position Within the clearance range. The same time as
Bearing is an important part of the mechanical parts, it can be said that the mechanical joints, and we humans, if there is no joint that is not enough, if there is no joint that paralyzed, and that what role? It is no use, the machine is the same, there is no bearing, the mechanical use is not up, so the machine is inseparable from the bearings, leaving the bearings on the live, it is tantamount to waste. The use of the bearing is very complex, and some need to cooperate with the use of rolling bearings, the general technical staff to know the knowledge, we certainly do not know the general people, we come here to tell you about the use of rolling bearings and requirements , But also familiar with the future you know the foundation of the RBI.
Select the cooperation should pay attention to the following four points:
(1) bearing ring circumferential surface should be well supported and uniform force to reduce the deformation, and can give full play to the bearing capacity. The same time as
(2) the ring in its mating surface can not slide along the tangential direction, otherwise it will damage the mating surface. The same time as
(3) free end bearings must be able to adapt to changes in the length of the shaft and bearing bore, that is, must have the ability to adapt to the axial position within a certain range of swimming.
(4) must pay attention to the installation and removal of bearings easy, save time and money.
