我們聊聊在機械設計中，我們必須掌握的有關軸轂聯接的知識！軸轂聯接是軸轂與軸相連接的軸上零件，常見齒輪、帶輪等。聯接使回轉零件在軸上定位和固定，以便傳遞運動和動力。

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.

矩形花鍵聯接是應用為廣泛的花鍵聯接。 應用廣泛。如航空發動機、汽車、燃氣輪機、機床、工程機械、拖拉機、農業機械及一般機械傳動裝置等等。漸開線花鍵的齒廓為漸開線，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)。

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).

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

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.

機用虎鉗結構缺點及使用中的隱患。機用虎鉗有結構簡單、夾緊力大、操作和維護方便等特點。但由于其必須具有廣泛的適用性和操作的便捷性，其螺母與絲桿之間、活動座與虎鉗體之間存在著較大的配合間隙，導致在裝夾一些加工精度要求較高的產品時難以達到要求。

The structural shortcomings of the machine vise and the hidden danger in the use. The machine tool has the characteristics of simple structure, large clamping force, easy operation and maintenance. But because of its wide applicability and convenient operation, there is a large gap between the nut and the screw rod, the movable seat and the vice body, which results in the difficulty of meeting some requirements when clamping some products with high machining accuracy.
