Principle of Operation

A battery is a device that converts chemical energy directly to electrical energy.   It consists of a number of voltaic cells; each voltaic cell consists of two   half cells connected in series by a conductive electrolyte containing anions and cations. One half-cell includes electrolyte and the electrode to which   anions   (negatively charged ions) migrate, i.e., the   anode   or negative electrode; the other half-cell includes electrolyte and the electrode to which   cations   (positively charged ions) migrate, i.e., the   cathode   or positive electrode. In the   redox   reaction that powers the battery, cations are reduced (electrons are added) at the cathode, while anions are oxidized (electrons are removed) at the anode.   The electrodes do not touch each other but are electrically connected by the   electrolyte . Some cells use two half-cells with different electrolytes. A separator between half cells allows io...

Gear Train

A   gear train   is formed by mounting   gears   on a frame so that the teeth of the gears engage. Gear teeth are designed to ensure the pitch circles of engaging gears roll on each other without slipping; this provides a smooth transmission of rotation from one gear to the next. •     A gear train is two or more gear working together by meshing their teeth and turning each other in a system to generate power and speed •       It reduces speed and increases torque •      Electric motors are used with the gear systems to reduce the speed and increase the torque Types of gear train §   Simple gear train §   Compound gear train §   Epicyclic gear train §   Reverted gear train

Construction & Working of Differential Assembly

Image
Torque   is supplied from the engine, via the   transmission , to a   drive shaft   (British term: 'propeller shaft', commonly and informally abbreviated to 'prop-shaft'), which runs to the   final drive unit   that contains the differential. A   spiral bevel   pinion   gear takes its drive from the end of the propeller shaft, and is encased within the housing of the final drive unit. This meshes with the large spiral bevel   ring   gear, known as the   crown wheel . The crown wheel and pinion may mesh in   hypoid   orientation, not shown. The crown wheel gear is attached to the differential   carrier   or cage, which contains the 'sun' and 'planet' wheels or gears, which are a cluster of four opposed bevel gears in perpendicular plane, so each bevel gear meshes with two neighbours, and rotates counter to the third, that it faces and does not mesh with. The two sun wheel gears are aligned on the same axis as...
