Description

This historic book may have numerous typos and missing text. Purchasers can usually download a free scanned copy of the original book (without typos) from the publisher. Not indexed. Not illustrated. 1913 edition. Excerpt: ... on the engine shaft is driving a larger gear on the counter shaft which in turn is driving the intermediate gear through a small spur pinion. When the sliding gear is moved over so that it is out of mesh with the large gear on the counter shaft and engaged directly with the intermediate drive gear, the highest speed ratio is obtained. The Differential Gear and Its Use.--The differential gearing is one of the most important parts of the gas tractor as well as the automobile. This arrangement of gearing permits the rear wheels to revolve at different speeds and at the same time act to drive the tractor. When a tractor turns a corner the inner wheel must revolve slower than the outer one because it is not covering as much ground. The differential gear makes this possible in a very simple manner. The construction of a typical differential gear is shown in outline at Fig. 111 in the form that it is usually employed on gas tractors. In this application the differential gear is mounted on a cross shaft, which is the usual method of installing it on both gas and steam-propelled traction engines. The bull pinion A is attached to a continuous shaft which passes through the center of the differential gearing and which is driven by the bevel gear A. The bull pinion B is attached to a sleeve forming part of bevel gear B and can revolve independently of the continuous through shaft when desired. The differential driving gear, which is turned by the source of power, is mounted independent of the continuous shaft and is coupled to bevel gears A and B only through the medium of bevel pinions C and D, which are attached to and revolve upon studs carried by the differential spider. v Assuming that all the gears are in mesh, as outlined, if the resistance...show more
