鍵是一種標(biāo)準(zhǔn)件,通常用于聯(lián)接軸與軸上旋轉(zhuǎn)零件與擺動零件,起周向固定零件的作用以傳遞旋轉(zhuǎn)運動和扭矩,楔鍵還可以起單向軸向固定零件。而導(dǎo)鍵、滑鍵、花鍵還可用作軸上移動的導(dǎo)向裝置。 根據(jù)鍵的結(jié)構(gòu)形式,鍵聯(lián)接可分為平鍵聯(lián)接、半圓鍵聯(lián)接、楔鍵聯(lián)接和切向鍵聯(lián)接等幾類。

The key is a standard part, which is usually used to connect the rotating parts and swing parts of the shaft and the axle to move the fixed parts to transmit rotary motion and torque, and the wedge key can also play a one-way axial fixation part. The guide, slippery key and the spline can also be used as a guiding device for moving on the axis. According to the structure of the key, key joins can be divided into a flat bond, a semicircle bond, a wedge bond and a tangent bond.


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)接按齒形的不同,可分為矩形花鍵和漸開線花鍵兩類,這兩類花鍵均已標(biāo)準(zhǔn)化。

矩形花鍵的定心方式為小徑定心,即外花鍵和內(nèi)花鍵的小徑為配合面。其特點是定心精度高,定心的穩(wěn)定性好,能用磨削的方法消除熱處理引起的變形。

The spline connection can be divided into two types: rectangular spline and involute spline. The two kinds of spline are standardized.

The centering way of the rectangular spline is the small diameter centering, that is, the small diameter of the outer spline and the inner spline is the matching surface. It is characterized by high centering precision and good stability of centering. It can be used to remove the deformation caused by heat treatment by grinding.



凡是在軸轂聯(lián)接中不用鍵、花鍵或銷時的聯(lián)接,統(tǒng)稱為無鍵聯(lián)接。無鍵聯(lián)接中我們介紹兩個常用的型面聯(lián)接和過盈配合聯(lián)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.
