Abstract
Apparatus for affecting positional adjustment of a machine member has an adjustment screw nonrotatably connected to the machine member and screwed into a nut formed as a worm wheel. The worm wheel, meshes with a worm, connected by a worm shaft to an actuator assembly for rotating the worm. The worm shaft is rotatably and axially displaceably mounted in a housing in which the worm wheel is rotatably mounted and the worm shaft is rotatably and axially non-displaceably mounted in a slider, which is guided in the housing for movement in the axial direction of the worm shaft. The slider is reciprocable by a fluid-operable piston-cylinder unit to an extent which corresponds to the desired adjustment of the screw.
Claims4
Apparatus for affecting positional adjustment of a first machine member with respect to a second machine member comprising:
- a housing;
- an adjustment screw nonrotatably connected to a machine member;
- a nut formed as a worm wheel;
- a worm, said worm meshing with said worm wheel;
- actuating means for rotating the worm;
- a worm shaft, said worm shaft operatively connecting said worm to said actuating means;
- displacement means rotating and axially displacing said worm shaft with respect to said housing;
- a slider, said worm shaft being mounted in said slider;
- a fluid operable piston-cylinder operatively connected to said slider;
- guide means for restricting the motion of said slider to an axial direction of the worm shaft when said slider is subject to force imparted by said fluid operable piston-cylinder to an extent limited by said actuating means.
