摘要： Portable friction welding apparatus comprises a drive motor (20) for causing relative rotation between a pair of workpieces (70, 71). An auxiliary energy store such as the flywheel (29) is mounted coaxially to a drive shaft (20') of the drive motor. The two workpieces may be urged together in response to movement of the motor (20) relatively to its supporting casing (1, 2). The flywheel (29) is adapted to provide sufficient energy such that the resultant resistive torque between the workpieces (70, 71) on initial contact is reduced to be substantially the same as or less than the driving torque of the drive means.

摘要： Friction welding apparatus comprises a housing (1, 2) and a workpiece support (20', 24) rotatably and axially movably mounted in the housing. An air driven motor (20) is coupled to the workpiece support (20', 24) to cause the workpiece support to rotate relatively to the housing. A compression spring (33) urges the workpiece support in a first axial direction relatively to the housing while a piston (7) responsive to air pressure is provided to move the workpiece support (20', 24) relatively to the housing (1, 2) in a second axial direction opposite to the first direction. Air under pressure is communicated through a common inlet (6) in the housing (1, 2) to a valve arrangement (8, 9, 13, 14) so that air is conveyed along a first path to the drive motor (20) and along a second path to the piston (7). The valve arrangement is such that axial movement of the piston (7) relatively to the housing (1, 2) causes the valve gradually to close thereby gradually stopping rotation of the motor (20). The second path remains open.
摘要翻译：摩擦焊接装置包括壳体（1,2）和可旋转和轴向可移动地安装在壳体中的工件支撑件（20'，24）。气动马达（20）联接到工件支撑件（20'，24）上，以使工件支撑件相对于壳体旋转。压缩弹簧（33）相对于壳体沿第一轴向方向推动工件支撑件，同时提供响应于空气压力的活塞（7），以相对于壳体（1,2）移动工件支撑件（20'，24））在与第一方向相反的第二轴向方向上。在压力下的空气通过壳体（1,2）中的公共入口（6）连通到阀装置（8,9,13,14），使得空气沿着第一路径被传送到驱动马达（20），并且沿着通向活塞（7）的第二路径。阀装置使得活塞（7）相对于壳体（1,2）的轴向移动使得阀逐渐关闭，从而逐渐停止电动机（20）的旋转。第二条路线保持开放。
