By 1921 the company was the largest worm gear manufacturer in the world.

At the center of the platform a handle turned a worm gear.

Take the "worm gears" on the top deck, for example.

Tom frantically worked the worm gear that opened the tower.

Probably he saw me enter, but how could he knew enough to work the worm gear and close the door?

This was connected to the worm gear final drive by a transmission shaft.

He is probably best known for applying worm gear drive to tramcars.

Four cogs, six screws, and a worm gear are left over, but the thing works.

Worm gears are used when large gear reductions are needed.

It is common for worm gears to have reductions of 20:1, and even up to 300:1 or greater.

Often a worm gearing is used to reduce the high output speed of the electric motor.

They contain anti-wear additives and are designed for worm gears.

Early trucks had a worm gear rear-end that limited the top speed of the truck.

Strange words from a man whose art literally revolves around worm gears and drive shafts.

How had she set the worm gear?

"The worm gear must have shut of itself.

Normally, worm gears provide a gear ratio of 14:1.

The reel should be an old bait-caster with the worm gear busted and the handle off.

I know that because we still make some little parts out of it, sleeve bearings mostly, and the worms for the big worm gears.

He decided to use a worm drive transmission and designed a machine to cut the worm gears.

It used a toothed index plate and a worm gear to advance the mechanism.

She bent back down and began turning a small crank handle connected to a worm gear that ran the length of the table.

Very heavy trucks, such as those used to carry aggregates, often use a worm gear differential for strength.

Drive was to the rear wheels through a live axle with worm gear final drive.

Worm wheels are first gashed to rough out the teeth and then hobbed to the final dimensions.

The second are single-throated worm gears, in which the worm wheel is throated.

Steering gear is by worm and worm wheel.

Hobbing is used to produce most throated worm wheels, but certain tooth profiles cannot be hobbed.

The process is performed on gashers or universal milling machines, especially in the case of worm wheels.

A worm wheel is fixed to the rotating platform and meshes with a worm in the base.

The leadscrew engaged with a worm wheel instead of the usual halfnuts.

Note that is process cannot be used on a small worm wheel that mate with a multiple threaded worm.

The worm wheel that engaged with the cogs set into the top of the tower was latterly a cast-iron one, replacing an earlier wooden one.

These don't have a throat, or groove, machined around the circumference of either the worm or worm wheel.

Michel mounted a mixer motor onto a standard machete, as well as a worm wheel gearbox and a 2 inch circular blade.

At the worm wheel, the different modules result in different addendum modification coefficients and rolling circle diameters at both flanks.

The three speed gearbox was in-unit with the engine and drove the rear wheels via a worm wheel type rear axle.

This disc can rotate freely, for indexing, or under the control of a worm (handwheel), with the worm wheel portion being made part of the actual table.

Gashing was first used to rough out worm wheels using a universal milling machine, but then dedicated gashers were built to rough out other types of gears.

A worm gear is usually meshed with a spur gear or a helical gear, which is called the gear, wheel, or worm wheel.

The speed ratio of shafts depends upon the relation of the number of threads on the worm to the number of teeth in the worm wheel or gear.

It is commonly used on worm wheels before hobbing, but also used on internal and external spur gears, bevel gears, helical gears, and gear racks.

Positioning goniometers typically use a worm drive with a partial worm wheel fixed to the underside of the stage platform meshing with a worm in the base.

No. 34: The Master Worm Wheel of the Hobbing Machine HRS-500, (machining by Hobbing machine of Rhein-Neckar from Germany in 1943).
