A worm drive is a gear arrangement in which a worm (which is a gear in the form of a screw) meshes with a worm wheel (which is similar in appearance to a spur gear). Its main purpose is to translate the motion of two perpendicular axes or to translate circular motion to linear motion (example: band type hose clamp ).The two elements are also ...
In 1913, they established a joint venture in America with Timken for Radicon worm drive units. By the end of World War I the workforce had increased from 200 to 1,000 as they started building propulsion units for warships, and drive mechanisms for armaments. By 1921 the company was the largest worm gear manufacturer in the world. [2]
The slewing drive is a modernized take on the worm drive mechanism, which dates back many centuries and was widely used during the Renaissance Era. Pappus of Alexandria (3rd century AD), a Greek mathematician, is credited with an early version of the endless screw, which would later evolve into the worm drive. [1]
The global worm reduction gearbox market is analyzed to reach US$ 4.13 billion by 2034. Global sales of worm reduction gearboxes are projected to rise at 5.8% CAGR from 2024 to 2034. The double-reduction gearbox segment is forecasted to reach a value of US$ 2.68 billion by 2034.
The final drive used an underhung worm reduction gear slung below the differential leaving little ground clearance (described by road testers as "nearly six inches") but permitting a flat floor to the rear passenger compartment. Road testers commented that the new suspension provided good stability and "avoided tiresome pitch and toss".
The transaxle configuration combines the gearbox and final drive in one housing and is only built in individual cases; In the transverse direction, the gearbox and final drive are very often combined in one housing due to the much more restricted space available; Every type of transmission occurs in every type of installation.
