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.

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。

螺旋副的間隙大，旋轉時費力，使用中穩(wěn)定性差。機用虎鉗開合行程大，螺旋副的運行長度較長，為保證能夠快速裝夾，（金屬加工真不錯）機用虎鉗螺旋副的螺距較大。較大的螺距意味著較大的螺旋升角，轉動單圈進給量較大，使用時較費力；較大的螺距需要更大的配合間隙來確保螺旋副的正常使用。

The clearance of the helix pair is large, the rotation is hard and the stability of the use is poor. The machine has large opening and closing stroke, and the operation length of the screw pair is longer. In order to ensure quick clamping, metal machining is good. Larger pitch means larger spiral angle, larger single turn feed and more laborious use. Larger pitch needs more fit clearance to ensure the normal use of screw pair.

裝夾過程及工作原理。鉗臺底座在設備工作臺上固定好后，先調(diào)整可調(diào)鉗口座在鉗體底座上的位置，確保裝夾行程內(nèi)能有效對工件進行裝夾；再將待加工產(chǎn)品置于柔性虎鉗的兩個鉗口之間。

Clamping process and working principle. When the clamping platform is fixed on the equipment worktable, the  of the adjustable jaw seat on the base of the clamp body is adjusted first, so as to ensure that the workpiece can be clamped effectively in the clamping stroke, and then the processed product is placed between the two jaw openings of the flexible vice.
