Abstract

For reduced vibration and uniform load distribution, a threaded spindle for linear drives is guided in a chamber, filled with an elastic packing material, which is positioned between the housing and the track along which the balls of the bearing move. Threaded spindle 1 is rotated by a motor (not shown), performing proportional linear motions in an axial direction in response to balls 3 engaging threads 2. Balls 3 are guided in wire windings 4 embedded in elastic packing material 5. Material 5 fills a chamber 6 formed by a metal sheath 7. Metal sheath 7 is provided with at least one hole 8 for injecting packing material 5. For producing this support means, hard metal wire 4 is initially wound around a master spindle with balls 3 resting against the threads.

Support Means for Threaded Spindle Running in Ball Bearing

For reduced vibration and uniform load distribution, a threaded spindle for linear drives is guided in a chamber, filled with an elastic packing material, which is positioned between the housing and the track along which the balls of the bearing move. Threaded spindle 1 is rotated by a motor (not shown), performing proportional linear motions in an axial direction in response to balls 3 engaging threads 2. Balls 3 are guided in wire windings 4 embedded in elastic packing material 5. Material 5 fills a chamber 6 formed by a metal sheath 7. Metal sheath 7 is provided with at least one hole 8 for injecting packing material 5. For producing this support means, hard metal wire 4 is initially wound around a master spindle with balls 3 resting against the threads. Then, elastic packing material 5 is injected into metal sheath 7 through hole 8. After curing, the master spindle is removed and threaded spindle 1 is inserted.
