我們聊聊在機(jī)械設(shè)計(jì)中，我們必須掌握的有關(guān)軸轂聯(lián)接的知識(shí)！軸轂聯(lián)接是軸轂與軸相連接的軸上零件，常見齒輪、帶輪等。聯(lián)接使回轉(zhuǎn)零件在軸上定位和固定，以便傳遞運(yùn)動(dòng)和動(dòng)力。

We talk about the mechanical design, we must master the knowledge about the shaft hub connection. Shaft hub connection is the axle hub and shaft connected to the shaft parts, common gear, belt wheel, and so on. The connection enables the rotating parts to be  and fixed on the axis to transmit motion and power.

楔鍵聯(lián)接：鍵的上下兩表面是工作面，鍵的上表面和輪轂鍵槽底面均有1∶100的斜度，裝配后，鍵即楔緊在軸和輪轂的鍵槽里，工作表面產(chǎn)生很大預(yù)緊力。

Wedge key connection: the upper and lower two surfaces of the key are the working faces. The upper surface of the key and the bottom of the hub keyway have 1 to 100 slope. After assembly, the key is wedged tightly in the keyway of the shaft and hub, and the working surface has a large pre tightening force.

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.

裝夾后產(chǎn)品靠近活動(dòng)鉗口附近容易上翹、抬起，多次裝夾一致性差。傳統(tǒng)機(jī)用虎鉗的螺旋副間隙較大，在使用中會(huì)產(chǎn)生較大振幅的振動(dòng)；而活動(dòng)座和虎鉗體之間的滑動(dòng)接觸面較大，采用的間隙也較大。

After the clamping, the product is easy to  and lifted near the movable jaw, and the cistency of the clamping is poor many times. The spiral pair clearance of traditional machine vice is bigger, which will cause large amplitude vibration in use. The sliding contact between movable seat and jaw vice body is larger, and the gap used is bigger.
