For worm gearboxes
Worm gears in continuous operation
Norelem now offers a wide range of worms and worm gears for the realization of worm gearboxes. They are available from stock in center distances from 17 to 80 mm, with several gear ratios available per center distance. The right-handed, case-hardened steel worms have ground flanks and bores.
Bronze was chosen for the worm gears due to its better sliding and emergency running properties, while the aluminum content ensures high chemical resistance. According to the manufacturer, the worm gears are suitable for continuous operation at high speeds and high torques. Most of them are supplied ready for installation and can be used without reworking. Several gear ratios are available per center distance. The background: Only worms and worm wheels with the same center distance or the same transmission ratio can be combined to form functioning worm and wheel sets. The center distances are available from stock in close increments from 17 to 80 mm.
A worm gear set is used for right-angled power transmission with simultaneous height offset (center distance of the crossed axles). The drive is usually provided by the worm gear. With a worm gearbox, very high ratios of up to 100:1 can be achieved with just one stage. Depending on the reduction ratio, self-locking is possible. sw
