聯(lián)接機(jī)廠家直銷(xiāo)在線咨詢

切向鍵聯(lián)接：它由兩個(gè)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(guò)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(gè)切向鍵只能傳遞一個(gè)方向的轉(zhuǎn)矩，傳遞雙向轉(zhuǎn)矩時(shí)，須用互成120°～130°角的兩個(gè)鍵。用于載荷很大，對(duì)中要求不嚴(yán)的場(chǎng)合。由于鍵槽對(duì)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.

機(jī)用虎鉗結(jié)構(gòu)缺點(diǎn)及使用中的隱患。機(jī)用虎鉗有結(jié)構(gòu)簡(jiǎn)單、夾緊力大、操作和維護(hù)方便等特點(diǎn)。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(dòng)座與虎鉗體之間存在著較大的配合間隙，導(dǎo)致在裝夾一些加工精度要求較高的產(chǎn)品時(shí)難以達(dá)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.
