Description
Technical field
The present invention relates to radial internal clearance predictor methods when a kind of four-point contact ball matching method and apolegamy.
Background technique
Bearing needs to carry out during trap the apolegamy of inner ring and outer ring according to clearance requirement.For with two-point contact
Common ball bearing for (such as deep groove ball bearing, angular contact ball bearing), due to its channel shape be circle, rolling element with
Trench bottom can contact, therefore its radial internal clearance can use formula (Gr=De-di-2·Dw) indicate, wherein GrFor the diameter of bearing
To clearance, DeFor bearing outer ring core diameter, diFor bearing inner race core diameter, DwFor rolling element diameter;Above-mentioned each value is ok
It is accurately measured by instrument.Internal and external cycle core diameter in this way convenient for being obtained according to measurement estimates the diameter of the bearing after trap assembles
To clearance, so that the radial internal clearance estimated according to these, which matches suitable Internal and external cycle progress bearing group, assembles efficiency with raising.
And for four-point contact ball, since its channel shape is peach-shaped, and rolling element and peach-shaped bottom of trench can not
It directly contacts, therefore the radial internal clearance of four-point contact ball cannot use formula (Gr=De-di-2·Dw) to indicate, and there is no at present
Simple and practical radial internal clearance expression formula calculates the radial internal clearance of four-point contact ball.Due to the diameter of four-point contact ball
It can not be determined before bearing assemble to clearance, therefore can not accurately match the radial internal clearance of four-point contact ball, assemble efficiency
It is low.
Summary of the invention
The purpose of the present invention is to provide a kind of for carrying out what radial internal clearance was estimated to the Internal and external cycle of apolegamy before assembling
Radial internal clearance predictor method when four-point contact ball is matched;Meanwhile the present invention also provides a kind of choosings of four-point contact ball
Method of completing the square.
