<*n style="font-size:14px;">螺旋副的间隙大，旋转时费力，使用中稳定性差。机用虎钳开合行程大，螺旋副的运行长度较长，为保证能够快速装夹，（金属加工真不错）机用虎钳螺旋副的螺距较大。较大的螺距意味着较大的螺旋升角，圣霖联接机多少钱，转动单圈进给量较大，使用时较费力；较大的螺距需要更大的配合间隙来确保螺旋副的正常使用。

<*n style="font-size:14px;">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 need*ore fit clearance to ensure the normal use of screw pair.<*n style="font-size:14px;">

装夹过程及工作原理。钳台底座在设备工作台上固定好后，先调整可调钳口座在钳体底座上的位置，确保装夹行程内能有效对工件进行装夹；再将待加工产品置于柔性虎钳的两个钳口之间。

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.

一个切向键只能传递一个方向的转矩，传递双向转矩时，圣霖联接机，须用互成120°～130°角的两个键。用于载荷很大，对中要求不严的场合。由于键槽对轴削弱较大 ，圣霖联接机采购，常用于直径大于100mm的轴上。

A tangent key can only transfer the torque of one direction. When the two-way torque i*ssed， the two keys of 120 to 130 degrees are required. An occasion for he*y 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.
