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.

与平键联接比较，花键联接在强度、工艺和使用方面有下列特点：在轴上与毂孔上直接而均匀地制出较多的齿与槽，故联接受力较为均匀；因槽较浅，齿根处应力集中较小，轴与毂的强度削弱较少。

Compared with the flat bond connection, the spline connection has the following characteristics in strength, process and use.More teeth and grooves are made directly and evenly on the shaft and hub hole, so the joint force is more uniform.

Because of the shallow groove, the stress at the root of the tooth is ***all, and the strength of the shaft and hub is weakened less.

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。
