Abstract: A new and improved rack and pinion steering gear including a housing, a rack bar having a rack gear thereon, and pinion head having a pinion gear thereon. The pinion head is supported on the housing for rotation as a unit with a steering hand wheel. The rack bar is supported on the housing for back and forth linear translation by a sleeve bearing and by a thrust bearing behind the rack bar opposite the pinion gear. The rack and pinion gears cooperate in converting manual effort applied at the steering hand wheel into linear thrust on the rack bar. Lateral separation between the rack gear and the pinion gear is "actively" suppressed by a thrust control apparatus including a primary spring continuously biasing the thrust bearing against the rack bar, a secondary spring, and an electronic solenoid operated clutch operable to engage the secondary spring between the thrust bearing and the housing when the lateral thrust between the rack and pinion gears is high and to disengage the secondary spring from between the thrust bearing and the housing when the lateral thrust between the rack and pinion gears is low.

Abstract: A transmission device for converting a torque from rotary to linear movement includes a rack having a plurality of teeth and a pinion having rollers which mesh with the teeth of the rack, with pressurization provided therebetween. The rack has an arcuate tooth flank diametrically greater than each of the rollers of the pinion. The rack also has a tooth face which has an approach profile progressively moving away from the path of contact of each of the rollers along which each of the rollers would otherwise engage with the tooth face. A plurality of each of the rollers of the pinion concurrently mesh with the corresponding teeth of the rack. Another embodiment converts a torque between rotary and linear movement and comprises a pinion having a plurality of teeth and a rack having a plurality of rollers to mesh with the teeth of the pinion. The device achieves reduced transmission resistance, a silent intermeshing movement with no substantial noise and vibration, as well as reduced wear on the teeth and rollers.

Abstract: A drive system for the conversion of a rotary motion into a linear motion contains a belt drive similar to a block and pulley system, and a system of a rack and pinion that is driven synchronously with the belt drive. The pinion and the rack are adjusted with respect to each other such that the teeth of the pinion engage with relatively large play in the rack. When driving under normal load, the drive takes place without loading of the rack and pinion system by the belt drive, so that the reversal backlash and the play of the rack and pinion system remain without effect on the displacement motion. When an overloading of the moving part and a corresponding stretching of the drive belt occur, the tooth flanks of the pinion and of the rack are supported against each other and in this manner prevent tearing or overloading of the drive belt. The drive system has a high reproducibility and a small reversal back-lash, and is particularly applicable for the drive of the focusing motion in microscopes with automatic repositioning by means of a drive motor.
