我們聊聊在機(jī)械設(shè)計中，我們必須掌握的有關(guān)軸轂聯(lián)接的知識！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)動和動力。

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.

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.

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(yán)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.
