Abstract:
1. A transmission apparatus for balance test operation, comprising a frame; a rotating disk fitted on the frame in a rotatable manner; two working platforms, the working platforms being fitted on the rotating disk in a symmetric and rotatable manner; each of the working platforms having a plurality of clamping jaws for clamping a work piece; an inner rotating member, the inner rotating member being fitted on the frame in a rotatable manner; a power source fixed on the frame; the power source being connected with a transmission gear for causing rotation of the transmission gear; a clutch joined to the inner rotating member in a movable manner; the clutch being capable of being engaged with and disengaged from the transmission gear; the clutch having plural engaging teeth on a first side thereof; the clutch and the inner rotating member being gong to rotate together when the clutch is engaged with the transmission gear at the engaging teeth thereof; and an actuating mechanism, the actuating mechanism being used for moving the clutch between a disengaged position and an engaged one, in which engaged position the clutch is engaged with the transmission gear; whereby after the rotating disk is rotated so as to make one of the working platforms face and securely joined to the inner rotating member, the actuating mechanism will exert force to separate the clutch from the transmission gear, and the clamping jaws clamp a work piece on said working platform, and next the actuating mechanism will make the clutch engage the transmission gear; thus, rotation of the power source will cause rotation of the transmission gear, the clutch, the inner rotating member, and said working platform so as to carry out a test in respect of balance of the work piece.
