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(kāi)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(diǎn)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.

矩形花鍵聯(lián)接是應(yīng)用為廣泛的花鍵聯(lián)接。 應(yīng)用廣泛。如航空發(fā)動(dòng)機(jī)、汽車、燃?xì)廨啓C(jī)、機(jī)床、工程機(jī)械、拖拉機(jī)、農(nóng)業(yè)機(jī)械及一般機(jī)械傳動(dòng)裝置等等。漸開(kāi)線花鍵的齒廓為漸開(kāi)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(shù))。

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).

漸開(kāi)線花鍵的定心方式為齒形定心。受載時(shí)齒上有徑向力，能起自動(dòng)定心作用，有利于各齒受力均勻，強(qiáng)度高，壽命長(zhǎng)。用于載荷較大，定心精度要求較高以及尺寸較大的聯(lián)接，如航空發(fā)動(dòng)機(jī)、燃?xì)廨啓C(jī)、汽車等。壓力角45°的花鍵多用于輕載、小直徑和薄型零件的聯(lián)接。

The involute spline is centering in the shape of the tooth. The tooth has radial force on the tooth, and it can play the role of automatic centering, which is beneficial to the uniform force of each tooth, high strength and long life. It is used for large load, high precision and large size connection, such as aero engine, gas turbine, automobile and so on. The spline with a pressure angle of 45 degrees is used for the connection of light, small diameter and thin parts.
