我們聊聊在機械設計中，我們必須掌握的有關軸轂聯(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.

花鍵聯(lián)接由內花鍵和外花鍵組成。內、外花鍵均為多齒零件，在內圓柱表面上的花鍵為內花鍵，在外圓柱表面上的花鍵為外花鍵。顯然，花鍵聯(lián)接是平鍵聯(lián)接在數目上的發(fā)展。

The connection of the spline is made up of the inner and outer spline. The inner and outer spline are multi tooth parts, and the spline on the surface of the inner cylinder is the inner spline, and the spline on the outer cylindrical surface is the outer spline. It is  that the spline connection is the development of the number of flat bond connecti.

勝過機用虎鉗的柔性虎鉗，在裝夾中能有效防止工件的翻轉、傾斜，克服了機用虎鉗因配合間隙大導致工件受力不均、加工發(fā)顫等現(xiàn)象；解決了現(xiàn)有輕型、精密工件加工時裝夾不可靠的問題。

Flexible than vice machine vise, the clamping can effectively prevent the workpiece turning and tilt, overcome the machine vise for clearance to workpiece uneven stress, etc. to solve the phenomenon of processing tremble; the existing light and precision workpiece clamping reliability of the fashion。

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(lián)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.
