切向鍵聯(lián)接：它由兩個普通楔鍵組成。其上下兩面（窄面）為工作面，其中之一面在通過軸心線的平面內(nèi)。工作面上的壓力沿軸的切線方向作用，能傳遞很大的轉(zhuǎn)矩。

Tangent key join: it cists of two common wedges. Both sides of the upper and lower sides (narrow surface) are working faces, one of which is in the plane of the axis of the axis. The pressure on the working face acts along the direction of the shaft and transmit a large torque.

一個切向鍵只能傳遞一個方向的轉(zhuǎn)矩，傳遞雙向轉(zhuǎn)矩時，須用互成120°～130°角的兩個鍵。用于載荷很大，對中要求不嚴的場合。由于鍵槽對軸削弱較大 ，常用于直徑大于100mm的軸上。

A tangent key can only transfer the torque of one direction. When the two-way torque is passed, the two keys of 120 to 130 degrees are required. An occasion for heavy load and no strict requirement. As the keyway is greatly weakened to the axis, it is often used on a shaft with a diameter larger than 100mm.

漸開線花鍵的定心方式為齒形定心。受載時齒上有徑向力，能起自動定心作用，有利于各齒受力均勻，強度高，壽命長。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)動機、燃氣輪機、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.

型面聯(lián)接：是利用非圓剖面的軸與相應(yīng)形狀的零件的轂孔配合而構(gòu)成的聯(lián)接，作為機械傳動中的聯(lián)接方式，型面聯(lián)接相對于傳統(tǒng)的鍵聯(lián)接相比，具有聯(lián)接強度高，沒有應(yīng)力集中，可以傳遞大扭矩且的同時也可以承受沖擊載荷，并且對于一些大型機械裝備來講其拆裝方便及維修便利。

is the hub hole type surface connection: the non-circular section axis and the corresponding shape parts with a connection, as the connection mode in mechanical transmission, compared with the traditional linkage type surface connection compared with connecting strength, no stress , can  large torque and high efficiency at the same time it can withstand the impact load, and for some large mechanical equipment for its disassembly and convenient maintenance.
