摘要
旋风磨头是用于粗磨机对瓷砖进行加工的执行部件,是比较新式的磨头,该磨头是采用八组高速旋转的金刚石砂轮对瓷质砖表面进行刚性磨削,对抛光砖进行粗加工,使砖面平整细滑,减小粗抛磨块的消耗量,降低生产成本,提高了生产效率。
本设计主要是对于旋风磨头的磨轮高速自转和磨头慢速公转进行结构设计和计算。由于两个传动的转速差较大采用两个电机分别进行驱动。磨轮的自转设计为大锥齿轮啮合八个小锥齿轮进行转动,用于实现金刚磨轮的高速自转,磨头的公转采用蜗轮蜗杆传动设计用来实现磨头的公转,并且分别对锥齿轮和蜗轮蜗杆进行了强度校核。本设计还对磨头中各轴、轴承和键进行了强度校核。使用CAD绘制完二维视图后还采用PRO/E建模对箱体壳体进行重量计算。

ABSTRACT
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 suption 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 and shell is done by PRO/E medeling.
