Abstract The tapered roller bearing is the fundamental unit of machine components and the key element of the mechanical equipment. And the tapered roller is an important part of tapered roller bearing. The differences in diameter sizes of tapered rollers can simultaneously affect such aspects as bearing clearance, rotation accuracy, friction moment, vibration and noise.
Through analysis of the principles of spherical fiducial surface location of the rollers, this paper verifies the feasibility of location method of spherical fiducial surface, chooses double inductive sensors differential measuring method to measure the diameters of the rollers and designs a diameter measurement system of tapered rollers.
This paper first introduces the mechanical structure design of the diameter measurement system of tapered rollers, which mainly consists of roller location machine, roller compression machine, diameter measurement machine and position limitation unit.
The measurement and control system part consists of hardware control part and software control part, which realizes the control over diameter measuring movement of tapered rollers, collection, analysis and handling of data, and manifestation of the results, ect.
The diameter measurement system of tapered rollers designed in this paper takes the spherical fiducial surface of the rollers as the location basis, uses the double inductive sensors differential measuring method, and realizes functions like automatic location and loading of rollers, automatic attainment and analysis of diameters of the rollers.
Key Words: tapered roller, diameter, automatic test, inductive sensors
