Introduction of the Bushes

     Bushes with high degree of standardization, high precision, compact structure, convenient installation and removal. By 8 givers cone and pulleys, sprockets and other transmission parts inside the cone compression connection, make a variety of transmission parts centering accuracy greatly improved. Drogue size standard design for the series. Which bore keyway according to ISO standard processing. Interchangeability good versatility for a variety of occasions when the transmission parts after a long operation, the inner hole and chain groove damage may occur, if you are using this drogue transmission parts, When this happens, simply replace the the same size can be restored using the sleeve. Thus greatly improving transmission parts life, reduce maintenance costs and save time.
       Bushes category:  TB, QD Bushes and STB sleeve of the points, with the pulley sleeve holes are matched at the half, and put the two light cone pulley hole and two threaded holes are constitute a complete hole, a threaded sleeve tapered bore of the pulley and an optical aperture formed on a complete hole. In the assembly, the two screws in the threaded holes of the two pulleys, with the threaded screw holes on the pulley constantly tighten the screw thread action cone pulley toward the small end, the tapered sleeve two optical aperture and is not completely processed to wear, so that when the screw head against the bottom of the aperture, it will force to the sleeve, the sleeve relative to the pulley of the pulley movement small end of cone, This is because the taper reasons, drogue has continually package tight shaft, and the shaft reacts on the sleeve, and then acting on the pulley. Such pulleys, taper sleeve and the shaft assembly on tightly together.

Taper Bush

     Conversely, when removing from the exit pulley screw threaded hole on the tapered sleeve with a threaded hole in the continuous process of tightening the screw is tapered toward the small end of the pulley direction, when the screw head against the pulley light bottom of the hole, it will force transmitted to the pulley, then the pulley on the relative Bushes to the pulley small end of cone direction, so that the pulley with taper suites are out of open, while the sleeve is also because of the loss from the pulley cone hole binding, coupled with its own recovery roundness some flexibility, but also with the shaft from the open.
     When the pulley and shaft sleeve are connected together to form an interference fit connector. Cone kit with key hole and shaft connected to transmit torque through the key and force. Bushes and although there is no linkage between the pulley, but there is a positive pressure joints, resulting friction can transmit torque and force.
