Power transmission arrangement for converting rotational movement into translational movement for dual pinion-steering gear for power steering of vehicle, has pinion shaft subjected with force, and rotor shaft held between worm wheels

摘要

The arrangement (1) has a drive worm (4) driven by an output shaft. Pinions (6, 8) and worm wheels (5, 7) are arranged on respective pinion shafts (13, 14). A toothed rack (9) includes two tooth series (10, 11), which are arranged parallel to each other. The pinions engage in the respective tooth series. The worm wheels engage on opposite sides in the drive worm. One of the pinion shafts is movably mounted in a direction to the drive worm and subjected with force. The rotor shaft is held between the worm wheels. The toothed rack is received between the pinion shafts by pressurization. The worm wheel includes a shaft made of molten plastic. An independent claim is also included for a method for mounting a power transmission arrangement with pinion shafts.
