Abstract: A radially adjustable gearwheel for driving a cylinder of an offset press. The gear rim has three axially disposed tapered bores into which axially tapered bolts can be pressed to act radially on the gear rim. Additional axial bores are provided between the tapered bores to form expansion webs in the gear rim. The tapered bolts, in conjunction with the expansion webs, subject the gear rim to varying radial deformation in a gently rising parabolic curve depending on the tension applied to the tapered bolts so that the deformed gearwheel rolls with minimal impact and shock forces.

Abstract: A gear reducer kit has one shaft mounted in a rotatable quill which rotates along an axis offset from the shaft axis. The quill may be fixed with respect to the gear reducer at one of several discrete index position, each associated with a different input pinion gear corresponding to the distance between the shaft and an idler gear. A flange rim guides the rotation of the quill mode with respect to the housing. The idler gear is opposed to the mounting base of the gear reducer with respect to the shaft to permit spacing plates to be added to adjust the mounting spacing.

Abstract: A gear wheel driven air compressor that is constructed as a piston compressor, the drive gear wheel of which, on the air compressor crankshaft, meshes with a gear wheel on the camshaft of the internal combustion engine. With drives of this type, the negative torque of the air compressor, which is produced once the upper dead center position of the air compressor piston has been reached, leads to a sudden flank change in the tooth mesh, which is associated with an unpleasant noise. In order to reduce this noise, it is known to make the meshing flank clearance as small as possible. However, clearances which are too small lead to increased rotational bending strain on the air compressor crankshaft and the camshaft. In order to prevent this, a sinusoidal meshing flank clearance change is proposed, which is obtained via a specific eccentricity of the air compressor drive gear wheel, which is associated with the upper dead center position of the air compressor piston.

Abstract: A concrete wall forming apparatus is described that facilitates formation of an elongated concrete wall between opposed sheet forms. An assemblable frame mounts the sheet forms in upright opposed orientations. The frame supports pairs of driven rollers that move against external surfaces of the sheet forms along the length of the wall as concrete is being poured. Each pair of rollers is driven by a selectively removable drive assembly including a single motor drive and gear arrangement by which both rollers of the pair are driven simultaneously. At least one of the rollers is connected to the driving gears through a clutch arrangement. The clutch may be selectively operated to disengage the roller at the inside of a corner, thereby allowing that roller to remain stationary while the remaining roller rotates to move about the outward radius of the corner.

Abstract: A drive linkage is provided between a drive shaft and a driven shaft, each being rotated on a fixed axis. The linkage includes a pair of intermediate gears between gears mounted concentrically on the drive and driven shafts, respectively, with links fixing the center-to-center distances of adjacent gears and maintaining neighboring gears in driving engagement. The linkage further includes a pair of control gears, a primary control gear being maintained in driving engagement with the drive gear through a pivotally mounted link, and a secondary control gear linked to the primary control gear and rotatably mounted to one of the intermediate gears through a pin near but offset from the centers of these gears. A selective positioning of the primary control gear causes an oscillation in the intermediate gear engaged with the driven gear, resulting in cyclical accelerations and decelerations in the driven gear responsive to a constant rotational speed in the drive gear.

Abstract: A recording and/or reproducing apparatus (1) for a record carrier (12) in tape form which extends between two hubs (10, 11) has, for driving the two hubs, two winding spindles (16, 17) which are each connected to one winding spindle wheel (22, 23). For driving the two winding spindle wheels (22, 23) peripherally, the apparatus (1) has a drive wheel (21) which can be motor-driven in opposite directions of rotation. For alternatively driving the two winding spindle wheels (22, 23) the drive wheel is displaceable between two operating positions. When its direction of rotation is changed, the drive wheel is automatically displaced from one to the other operating position, whereby for its displacement the drive wheel (21) rolls peripherally along an associated rolling surface (73) which is provided on a roller member (51).

Abstract: A gear wheel drive air compressor which is constructed as a piston compressor, the drive gear wheel of which on the air compressor crankshaft meshes with a gear wheel on the camshaft of the internal combustion engine. The inventive construction prevents the reverse acceleration of the camshaft drive gear wheel and minimizes the knocking pulse and noise in the mesh of the camshaft gear wheel in that the transmission ratio between the air compressor drive gear wheel and the camshaft gear wheel is embodied as a multiple load cycle of the camshaft drive torque, and at the same time the angular position of the air compressor crankshaft relative to the camshaft is fixed such that negative torque components of the air compressor crankshaft are eliminated by the overlapping of positive torque components of the camshaft. Furthermore, the air compressor drive gear wheel is arranged in alignment with the air compressor crankshaft.

Abstract: In a multiple-step gear drive there are two stationary toothed wheels, comprising a driving wheel and a driven wheel. Their spacing and positions remain constant as the housing that supports gear trains is rotated. For each gear step or position there is a gear train. Each train comprising one or several gear-wheels and in engagement with each other, all these gear-wheels being rotatably jounalled in a housing. The housing is movable substantially parallel to a plane running perpendicular to the shafts of the stationary toothed wheels, to be brought into a specific engagement position for each gear step in which the gear train is in engagement with both stationary toothed wheels. The housing and gear wheels are thus arranged so that in at least one gear step the housing can be disengaged from its engaged position in two substantially opposite directions, thus moving the corresponding gear train in the selected direction and thereby breaking the driving connection between the two stationary toothed wheels.

Abstract: A gear train comprises a central wheel for rotation about a central axis and a plurality of pinions engaged with either inner or out circumferential teeth of the central wheel. The pinions are mounted on shafts and have teeth which are meshed with the teeth of the central wheel. A relative position of the pinion and central wheel teeth is influenced through external adjusting forces applied to the wheel and pinions. To this end, the pinions are mounted in active magnetic bearings whose magnetic force is controlled through sensors which sense the radial position of the central wheel. In this way, the radial position of the pinion shafts can be controlled using the magnetic bearings and as a function of the radial position of the circumference of the central wheel to maintain a desired spacing between the wheel and pinion teeth. This control can be used to compensate for centrifugal and thermal expansion or contraction forces.

Abstract: A telescopic assembly includes a yoke supported for rotation on a stationary member, a shaft fitted in telescoping relation inside the yoke, rotatably supported by a movable bracket and capable of being reciprocated together with the movable bracket relative to the yoke, a screw rotatably retained by a stationary bracket, and a nut threadedly engaged with the screw and fixed to the movable bracket. When the screw is rotated, the nut provided on the movable bracket moves axially along the screw so that the movable bracket is moved toward or away from the stationary bracket. Hence, the shaft supported by the movable bracket is displaced axially forward or backward, depending upon the direction of screw rotation, relative to the yoke, thereby enabling the portion of the shaft projecting from the yoke to be adjusted in length.
