WORM GEAR DRIVE LOCKING APPARATUS |
摘要 |
A worm gear is connected to a machine tool component and has teeth mating with teeth on a power driven worm rotatably supported by a housing enclosing the worm. A clamping shoe is supported for sliding movement within a slot in the housing and has a compound curved inner surface positioned to engage the teeth on the worm. A cam shaft is supported for rotation by the housing and extends laterally through a hole within the clamping shoe. A fluid cylinder is connected to rotate the cam shaft for moving the clamping shoe radially between a released position and a clamping position pressing the teeth on the worm against the teeth on the worm gear by slightly deflecting the worm to lock the head from any movement. |
