れる。(Problem to be solved by the invention) In the above case, the cam pulley is removed after the engine is delivered to the engine assembly station. The work requires time to assemble the crank pulley and wind the timing belt.In this case, a jig table that moves forward and backward toward the engine is prepared for the assembly station, and the valve drive camshaft and crank A cam pulley and a crank pulley can be freely set at each position facing the shaft, and a dummy day IJ'i is provided on the jig stand facing the auxiliary pulley, and the cam pulley and crank pulley are set on the jig stand in advance. The timing belt is fully wrapped between both pulleys and the dummy pulley, and after the engine is brought in, the cam pulley and Did you complete the fitting with the crank pulley and pushing the timing belt on the dummy pulley into the auxiliary pulley? It is conceivable to improve the efficiency of the assembly work by doing so.

何にするかが問題となる。In this case, the valve drive camshaft and crankshaft are aligned in advance (I and held in this blank position), so it is necessary to set the cam pulley and crank pulley on the jig stand in the phase corresponding to each +h++. As the jig table moves forward, each pulley is fitted to each shaft, but since the internal friction of the replacement fluid pulley is relatively small and it can easily rotate, it is difficult to push the timing belt into the auxiliary pulley. It is necessary to align the two, and the problem is how to do this.

るタイミングベルトの組付装置。The cam pulley and crank pulley are mounted on a jig stand that moves back and forth toward the engine, in which the valve train camshaft, crankshaft, and auxiliary pulley are installed, so that the axes of these shafts and the axes of the respective shafts are on the same axis. each set member that is held in alignment with the axis and in phase with each axis, and the pulley is pushed from each set member onto each axis by advancing the jig stand toward the engine. At the same time, a dummy pulley is provided on the jig stand so as to be located on the same axis as the axis of the auxiliary pulley, so that the timing belt can be freely passed between each of the pulleys and the dummy pulley. Timing in an engine characterized in that a drive shaft that engages with and rotates the auxiliary pulley is provided on the inner periphery of the dummy pulley, and a pressing member that pushes the timing belt forward is provided on the outer periphery of the dummy pulley. Belt assembly device.
