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.

與平鍵聯(lián)接比較，花鍵聯(lián)接在強(qiáng)度、工藝和使用方面有下列特點(diǎn)：在軸上與轂孔上直接而均勻地制出較多的齒與槽，故聯(lián)接受力較為均勻；因槽較淺，齒根處應(yīng)力集中較小，軸與轂的強(qiáng)度削弱較少。

Compared with the flat bond connection, the spline connection has the following characteristics in strength, process and use.More teeth and grooves are made directly and evenly on the shaft and hub hole, so the joint force is more uniform.

Because of the shallow groove, the stress at the root of the tooth is small, and the strength of the shaft and hub is weakened less.

銷聯(lián)接一般用來(lái)傳遞不大的載荷或作安全裝置；另一作用是起定位作用。常與帶孔螺栓和六角開槽螺母配對(duì)使用，把銷插入螺栓的孔與螺母的槽中，以防螺母松脫。銷按形狀分為圓柱銷、圓錐銷和異形銷三類。

Pin connecti are generally used to transfer small loads or safety devices; the other is to play the role of . It is often paired with hole bolts and six angle slotting nuts to insert the pin into the hole of the bolt and the slot in the nut so as to prevent the loosening of the nut. The pin is divided into three types: cylindrical pin, conical pin and special pin.

機(jī)用虎鉗結(jié)構(gòu)缺點(diǎn)及使用中的隱患。機(jī)用虎鉗有結(jié)構(gòu)簡(jiǎn)單、夾緊力大、操作和維護(hù)方便等特點(diǎn)。但由于其必須具有廣泛的適用性和操作的便捷性，其螺母與絲桿之間、活動(dòng)座與虎鉗體之間存在著較大的配合間隙，導(dǎo)致在裝夾一些加工精度要求較高的產(chǎn)品時(shí)難以達(dá)到要求。

The structural shortcomings of the machine vise and the hidden danger in the use. The machine tool has the characteristics of simple structure, large clamping force, easy operation and maintenance. But because of its wide applicability and convenient operation, there is a large gap between the nut and the screw rod, the movable seat and the vice body, which results in the difficulty of meeting some requirements when clamping some products with high machining accuracy.
