Analysis of bearing the use of the environment requirements

Time:2016.11.28 News Sources:Shandong Xinkaite bearing Co.,Ltd. Views:
Correctly grasp the use of bearings in the mechanical parts and conditions of use and environmental conditions is the premise of selecting the appropriate bearing. To this end, the following data and information need to be obtained:
(1) the function and structure of the mechanical device
(2) the use of bearing parts
(3) bearing load (size, direction)
(4) rotational speed
(5) vibration, shock
(6) bearing temperature (ambient temperature, temperature)
(7) Ambient atmosphere (Corrosivity, cleanliness, lubricity) Selection of Bearing Arrangement Generally, the shaft is supported by two bearings in radial and axial directions. At this time, the bearing on one side is called fixed side Bearings, it bear radial and axial load, from the fixed shaft and bearing box relative axial displacement between the role.
The other side called the free side, only to withstand the radial load, the axial relative movement can be solved in order to solve the temperature change caused by the expansion of the shaft and install the bearings of the interval error. For fixed-side bearings, select the bearings that can be moved in the axial direction (eg cylindrical roller bearings) or on the mounting surface (eg radial ball bearings). On shorter shafts, where the fixed side is on the same side as the free side, axially movable shafts (such as radial thrust ball bearings) are fixed with only deep groove balls.
