J69 contact angle of bearing measuring instrument

• • • • • • • The instrument, ZYS developed, is specified for contact angle measurement, which applies planetary gear train principle, namely which is to fix the inner ring, balls and outer ring rotation at a certain ratio. The ratio is a function of bearing contact angle. By setting the rotational speed of cage, the instrument will measure corresponding rotational speed of outside ring. After being processed by the computer, the contact angle value will be shown.
