近读《设备管理与维修》1997年11期路剑峰文“一种新型带轮结构——锥套紧缩式带轮”,感到文中介绍的这种带轮结构仍有一些不完善之处:锥形紧缩套和带轮的紧固螺孔及顶出螺孔都采用半孔,且非通孔,工艺复杂,不便加工;这些螺孔需配钻,互换性差,不便于实现标准化;紧固螺钉孔和顶出螺钉孔都只有半边有螺纹,螺钉不易拧紧,安装时需锤击锥形紧缩套,而且由于光孔(半孔)孔径比螺纹大径稍大,如果传递的转矩
Recently, “equipment management and maintenance” 1997 the 11 road Jianfeng Wen “a new type of pulley structure - tapered sleeve shrink wheel”, I feel the article describes the structure of this pulley there are still some imperfections: Conical shrink sleeve and pulley fastening screw holes and the top of the screw holes are used half hole, and non-through hole, the process is complex, inconvenient to process; these holes need to be drilled, interchangeability is poor, not easy to achieve standardization; tight Screw hole and the top of the screw holes are only half of the screw thread, the screw is not easy to tighten the cone hammer to install tapping sets, and because the aperture (half hole) diameter larger than the major diameter of the thread, if the transfer of torque
