轴毂联接的方式有键联接、花键联接、成形联接、胀套联接、销联接、紧定螺钉联接、过盈联接等，有些联接方式仅用于轴毂联接，有些联接方式可兼作其它联接。键和花键是常见的轴毂联接方式。

The way of shaft hub connection includes key connection, spline connection, forming connection, expansion sleeve connection, pin connection, tight screw connection and interference fit. Some connection ways are only used for hub connection, and some connection ways can be used as other connecti. Key and spline are the most common hub connecti.

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，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.

胜过机用虎钳的柔性虎钳，在装夹中能有效防止工件的翻转、倾斜，克服了机用虎钳因配合间隙大导致工件受力不均、加工发颤等现象；解决了现有轻型、精密工件加工时装夹不可靠的问题。

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。

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.
