聯接機生產商承諾守信

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.

切向鍵聯接：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。工作面上的壓力沿軸的切線方向作用，能傳遞很大的轉矩。

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.

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.

機用虎鉗的結構及原理。機用虎鉗是機械加工中常用的裝夾機構，其結構如圖1所示。其主要工作原理：轉動方頭帶動絲杠，在螺母（通過緊固螺釘固定在虎鉗體上）的作用下，做螺旋運動的絲杠帶動與之聯接的活動座沿絲杠軸線方向來回移動。

The structure and principle of machine vise. Machine vise is a common clamping mechanism in mechanical processing. Its structure is shown in Figure 1. The main principle: rotation of the lead screw nut in the square, (fixed in the vise body through a fastening screw) under the action of moving spirally driven screw connected with the movable seat to move back and forth along the screw axis.
