軸轂聯(lián)接的方式有鍵聯(lián)接、花鍵聯(lián)接、成形聯(lián)接、脹套聯(lián)接、銷(xiāo)聯(lián)接、緊定螺釘聯(lián)接、過(guò)盈聯(lián)接等，有些聯(lián)接方式僅用于軸轂聯(lián)接，有些聯(lián)接方式可兼作其它聯(lián)接。鍵和花鍵是常見(jiàn)的軸轂聯(lián)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.

花鍵聯(lián)接由內(nèi)花鍵和外花鍵組成。內(nèi)、外花鍵均為多齒零件，在內(nèi)圓柱表面上的花鍵為內(nèi)花鍵，在外圓柱表面上的花鍵為外花鍵。顯然，花鍵聯(lián)接是平鍵聯(lián)接在數(shù)目上的發(fā)展。

The connection of the spline is made up of the inner and outer spline. The inner and outer spline are multi tooth parts, and the spline on the surface of the inner cylinder is the inner spline, and the spline on the outer cylindrical surface is the outer spline. It is  that the spline connection is the development of the number of flat bond connecti.

勝過(guò)機(jī)用虎鉗的柔性虎鉗，在裝夾中能有效防止工件的翻轉(zhuǎn)、傾斜，克服了機(jī)用虎鉗因配合間隙大導(dǎo)致工件受力不均、加工發(fā)顫等現(xiàn)象；解決了現(xiàn)有輕型、精密工件加工時(shí)裝夾不可靠的問(wèn)題。

Flexible than vice machine vise, the clamping can effectively prevent the workpiece turning and tilt, overcome the machine vise for clearance to workpiece uneven stress, etc. to solve the phenomenon of processing tremble; the existing light and precision workpiece clamping reliability of the fashion。

螺旋副的間隙大，旋轉(zhuǎn)時(shí)費(fèi)力，使用中穩(wěn)定性差。機(jī)用虎鉗開(kāi)合行程大，螺旋副的運(yùn)行長(zhǎng)度較長(zhǎng)，為保證能夠快速裝夾，（金屬加工真不錯(cuò)）機(jī)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(zhuǎn)動(dòng)單圈進(jìn)給量較大，使用時(shí)較費(fèi)力；較大的螺距需要更大的配合間隙來(lái)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.
