键联接在苏联发明了一种新的键联接。由于键同轴与套筒的接触总面积增加，故键的承载能力提高了。除此之外，由于用铣键槽代替插键槽，故此联接的制造生产率也提高了。该联接由轴１，套筒２，两排键４和７，盖３．套筒２上的螺纹孔８，螺钉６组成。横过轴铣出一个贯通的键... Bond in the Soviet Union invented a new bond. Due to the increased contact area between the key and the sleeve, the load capacity of the key is increased. In addition, the manufacturing productivity of the coupling is also improved because the keyway is replaced by the keyway. The coupling consists of shaft 1, sleeve 2, two rows of keys 4 and 7, Sleeve 2 threaded holes 8, 6 screws. Through the shaft milling a through key ...
