键是一种标准件，通常用于联接轴与轴上旋转零件与摆动零件，起周向固定零件的作用以传递旋转运动和扭矩，楔键还可以起单向轴向固定零件。而导键、滑键、花键还可用作轴上移动的导向装置。 根据键的结构形式，圣霖国际联接机选购，键联接可分为平键联接、半圆键联接、楔键联接和切向键联接等几类。
The key is a standard part， which is usually used to connect the rotating parts and swing parts of the shaft and the axle to move the fixed parts to tran***it rotary motion and torque，圣霖国际联接机， and the wedge key can also play a one-way axial fixation part. The guide， slippery key and the spline can also be used as a guiding device for moving on the axis. According to the structure of the key， key joins can be divided into a flat bond， a semicircle bond， a wedge bond and a tangent bond.
销联接一般用来传递不大的载荷或作安全装置；另一作用是起***作用。常与带孔螺栓和六角开槽螺母配对使用，圣霖国际联接机生产，把销插入螺栓的孔与螺母的槽中，以防螺母松脱。销按形状分为圆柱销、圆锥销和异形销三类。
Pin connecti are generally used to transfer ***all loads or safety devices; the other is to play the role of . It is often paired with hole bolts and six angle slotting nuts to insert the pin into the hole of the bolt and the slot in the nut so as to prevent the loosening of the nut. The pin is divided into three types: cylindrical pin， conical pin and special pin.
切向键联接：它由两个普通楔键组成。其上下两面（窄面）为工作面，圣霖国际联接机价格，其中之一面在通过轴心线的平面内。工作面上的压力沿轴的切线方向作用，能传递很大的转矩。
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 tran***it a large torque.
