近年来,国外出现许多新颖的无键联结,在引进的设备中能经常见到。其特点就是在传动轴上不用键联结,因此也无须加工键槽,既减少了加工工序,又降低了成本,目前这种形式的无键联结已成为很有发展前途的工具。一、几种新型的无键联结1.锥型环式无键联结 In recent years, there have been many novel bondless connections abroad that can often be seen in imported equipment. Its characteristic is that there is no key connection on the transmission shaft, so there is no need to process the keyway, which not only reduces the processing work but also reduces the cost. At present, this form of keyless connection has become a promising tool. First, several new types of bond-free 1. Cone-type ring-free bond
