points of the teeth coinciding, as in the usual practice, these teeth are actually staggered to ensure that all the teeth on one side of a good wheel are opposite the spaces between your pearly whites belonging IC) the spouse of the steering wheel. It is found that these gear wheels arc practically noiseless owing to the absence of again lash. The clutches that control the locking of the wheels giving the different gear ratios are often adjusted to take up have on, without dismantling the gear-box.

they run in bushes of phosphor-bronze, and ball-bearings are interposed between the ends of the worm and the bushes. The illustration of the complete back axle shows the structure which is perfect for commercial vehicles, and the differ ential gearing, which is definitely of the bevel pinion type, is included within the worm wheel.

THE ENERGY Plant Company also may make a speciality of a gear-box, the wheels where are always in mesh, and so are locked by means of friction clutches. The gear wheels are all of the double helical type, and the reducing of this forms the subject of a individual patent. Rather than the central

The manufacturers claim that, by this particular system, only to %. of the power is lost in friction. The most common practice is to cut the worms with a single thread, but, for reductions of speed between the worm and wheel of significantly less than 8 to at least one 1, multiple threads are employed. The complete unit is supplied in a dirt and oil-retaining case, which includes an inspection beginning at its higher part. In the typical design the worm is placed beneath the wheel, where it revolves in a bath of essential oil. The worm shafts are manufactured from mild steel, and are afterwards hardened and floor true;

The ” Globoid ” Worm Gear.
The gear can be adapted to a variety of purposes, such as driving machine tools, hoisting equipment, or in practically any circumstance where a silent reduction of initial velocity is desirable. The makers have got turned their focus on certain requirements of the motorbus and lorry builder, and are now prepared to supply complete hack axles for any type of motor vehicle which is motivated by a cardan shaft. The worm wheel in this particular system has, rather than the usual cut pearly whites, revolving rollers which happen to be carried on hardened, and ground, metal pins fixed in to the circumference of the nice wheel. The rollers, as could be observed in the illustration, happen to be of conical form, and the worm is trim to fit these accurately. The products for the various parts are selected so that the metal used in the making of the rollers is softer than either the pins, which they revolve, or the worm. Consequently, if any wear should happen after long use, it is an easy matter to replace the worn rollers. This characteristic is a significant one on the score of economy, because instead of the entire worm and wheel having to be changed at much cost, only the tiny parts must be renewed.
