軸轂聯接的方式有鍵聯接、花鍵聯接、成形聯接、脹套聯接、銷聯接、緊定螺釘聯接、過盈聯接等，有些聯接方式僅用于軸轂聯接，有些聯接方式可兼作其它聯接。鍵和花鍵是常見的軸轂聯接方式。
The way of shaft hub connection includes key connection, spline connection, forming connection, expansion sleeve connection, pin connection, tight screw connection and interference fit. Some connection ways are only used for hub connection, and some connection ways can be used as other connecti. Key and spline are the most common hub connecti.
矩形花鍵聯接是應用為廣泛的花鍵聯接。 應用廣泛。如航空發動機、汽車、燃氣輪機、機床、工程機械、拖拉機、農業機械及一般機械傳動裝置等等。漸開線花鍵的齒廓為漸開線，分度圓壓力角α有30°及45°兩種。齒頂高分別為0.5m和0.4m(m為模數)。
The rectangular spline connection is the most widely used spline connection. It is widely used. Such as aero engine, automobile, gas turbine, machine tool, engineering machinery, tractor, agricultural machinery and general mechanical transmission equipment and so on. The tooth profile of the involute spline is involute, and the pressure angle of the dividing circle is 30 and 45 degrees. The top of the tooth is 0.5m and 0.4m respectively (M is the modulus).
凡是在軸轂聯接中不用鍵、花鍵或銷時的聯接，統稱為無鍵聯接。無鍵聯接中我們介紹兩個常用的型面聯接和過盈配合聯接。
The connection of no key, spline or pin in the hub connection is called the keyless connection. In keyless joins, we two commonly used type face joins and interference fit connecti.
螺旋副的間隙大，旋轉時費力，使用中穩定性差。機用虎鉗開合行程大，螺旋副的運行長度較長，為保證能夠快速裝夾，（金屬加工真不錯）機用虎鉗螺旋副的螺距較大。較大的螺距意味著較大的螺旋升角，轉動單圈進給量較大，使用時較費力；較大的螺距需要更大的配合間隙來確保螺旋副的正常使用。
The clearance of the helix pair is large, the rotation is hard and the stability of the use is poor. The machine has large opening and closing stroke, and the operation length of the screw pair is longer. In order to ensure quick clamping, metal machining is good. Larger pitch means larger spiral angle, larger single turn feed and more laborious use. Larger pitch needs more fit clearance to ensure the normal use of screw pair.
