Chosen bearing, should be based on the actual working conditions, first determine the type of the bearing, and then calculation is selected bearing the relevant data, to audit the performance of the selected bearing, select the bearing lubricant and lubrication method to determine bearing and related components with the fastening, pretension, installation and removal of the way. The specific choice elements are as follows:
1, the rolling bearing selection
(1) Rolling outside uninstall the determination of the charge.
(2) Rolling choice.
(3) bearing material selection.
(4) the choice of rolling bearing clearance.
(5) the choice of rolling bearing tolerance class.
2, the rolling bearing selection and calculation
(1) Calculation of rolling bearing reliability.
(2) calculation of rolling bearing fatigue life.
(3) Rolling equivalent dynamic load calculations.
(4) the calculation of the rolling bearing friction torque.
3, rolling bearing performance audit
(1) audit of the rolling bearing static strength.
(2) Rolling audit of the limit speed.
(3) Rolling swing angle of the audit.
(4) the rolling bearing self-aligning performance audit.
4, the rolling bearing lubrication choice
(1) the choice of rolling bearing lubrication.
(2) Rolling lubricant selection.
(3) the determination of the amount of lubricant of the rolling bearing.
(4) the determination of the replacement cycle of rolling bearing lubricants.
5, rolling bearing applications design
(1) with the determination of the rolling bearing.
(2) determination of the shaft and the bearing bore tolerance.
(3) Rolling axial fastening and preload design.
(4) Rolling seal options.
(5) mounting and dismounting of rolling bearings.
