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.

花键联接由内花键和外花键组成。内、外花键均为多齿零件，在内圆柱表面上的花键为内花键，在外圆柱表面上的花键为外花键。显然，花键联接是平键联接在数目上的发展。

The connection of the spline is made up of the inner and outer spline. The inner and outer spline are multi tooth parts, and the spline on the surface of the inner cylinder is the inner spline, and the spline on the outer cylindrical surface is the outer spline. It is that the spline connection is the development of the number of flat bond connecti.

凡是在轴毂联接中不用键、花键或销时的联接，统称为无键联接。无键联接中我们介绍两个常用的型面联接和过盈配合联接。

The connection of no key, spline or pin in the hub connection is called the keyless connection. In keyless joins, we two commonly used type face joins and interference fit connecti.

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.
