A whirling wheelhead on a rasping machine is an executive unit that is used to process the ceramic tile, and it is a new type. The wheelhead uses eight groups high- speed whirling diamond grinding wheel to grind the surface of porcelain brick., and process minimally to the polishing brick in order to make the surface even and lubricious, then it can minish the comsuption of unprocessed brcik, reduce the production cost and improve productivity and efficiency.
This design is mainly on contruction designming and calculation of the high-speed rotation of grinding wheel and slow-speed revolution of wheelhead. Because of the difference of rotate speed of the two drives, so it has to use two electric machine to drive. The rotation of grinding wheel is degined into a big bevel gear running with eight samll bevel gear in mesh, so as to realize the high-speed rotation of diamond grinding wheel. Worm wheel and worm transmission designment is used to realize the revolution of it. And this design checks the strength of gear and the worm wheel, axis, bearing and bond separately. Two-dimensional view is drawn by CAD, and the weight calculation of the cabinet and shell is done by PRO/E medeling.
