Abstract
A lower side coupling of a Hirth coupling is coaxially coupled and fixed to a spindle, an upper side coupling of the Hirth coupling is coaxially coupled and fixed to a lower rim, the upper side coupling of the lower rim is meshed with the lower side coupling of the spindle, and upward separation of the lower rim from the spindle is prevented by chuck mechanisms.
Claims5
A rim exchange device in a tire balance measurement apparatus for driving and rotating upper and lower rims nipping a tire by a spindle coupled to the lower rim and measuring dynamic balance of the tire, the rim exchange device comprising:
