Abstract
PURPOSE: To obtain a large variable ratio, by providing a bevel gear as a pinion coupled to a steering shaft and by curving the central part of a rack so that its position of engagement with the pinion can be displaced along the standard pitch cone surface of the bevel gear.
CONSTITUTION: A pinion 1, which is coupled to a steering shaft (not shown in Fig.) through a serration part 1a, is a bevel gear which has straight or curved teeth defined by a standard pitch cone surface with an appropriate circular cone angle of α. The central part of a rack 5, which is supported by a housing 4 slidably in the direction of the length and engaged with the pinion 1, is so curved that the position of engagement of the rack with the pinion can be continuously displaced to a maximum displacement quantity Z by the rotation of the pinion 1, on a plane along the standard pitch cone surface of the pinion, centering the point A of engagement with the pinion in the neutral position of the rack. According to this constitution, the effective pitch circle radius in the engagement is changed from x to y by the rotation of the pinion 1.
