A gearbox is characterized by its gear ratio i or its time T. Gear ratio i is the ratio of input speed ne and output speed na. T is the time for one revolution of the output shaft. Permissible Torque. The lifetime of a gearbox is determined by the load on the gear teeth and the number of revolutions of the gear wheels.

Oval gear meters are traditional, mechanical, positive displacement (PD) flow meters, first invented more than 50 years ago by OVAL Corporation of Japan and now widely used for flow metering applications..

How Spur Gears Work. The most commonly used type of gears is spur gears. Also called straight-cut gears, they have straight teeth that are cut or inserted parallel to the gear's shaft on a circular gear body. In mated pairs, these gears employ the parallel axes configuration to transmit motion and power.

Working of Differential :-So, first the power is transferred from engine's drive shaft to pinion gear, since the pinion gear & ring gear are meshed, power flows to ring gear.As the spider gear is connected with the ring gear, power flows to it. Finally from the spider gear, power gets transferred to …

The teeth of the gear are principally carved on wheels, cylinders or cone. Many devices that we use in our day to day life there working principle as the gear. Often gears that are meshed together will be of different sizes. In this case, The smaller gear is referred to as the pinion and; The larger one is simply referred to as the gear.

In an internal gear pump fluid enters int the suction port between the rotor and idler( it is a small interior gear) teeth. The fluid travel through the pump between the the teeth of the "gear-within-a-gear" principle.Liquid enters the suction port between the rotor (large exterior gear) and idler (small interior gear) teeth.

Working Principle of DC Servo Motor A DC servo motor is an assembly of four major components, namely a DC motor, a position sensing device, a gear assembly, and a control circuit. The below figure shows the parts that consisting in RC servo motors in which small DC motor is employed for driving the loads at precise speed and position.

Differential is an arrangement of gears which work together and allow the vehicle to take a turn smoothly. In the differential, bevel pinion gear is fixed to the propeller shaft which rotates the crown wheel. The crown wheel has another unit called the differential unit. It consists of two bevel gears (sun gear) and two bevel gears (planet gear).

Working Principle. The gear pump working principle can be explained as follows: When there is a revolution of toothed wheels inside of the casing section, air will get wedged in between and throughout the teeth which creates space. This shows a result of a positive up direction lift of the liquid on the way to the suction pump.

Working Principle of Planetary Gears. The principle of fixed gear transmission is very simple. In a pair of intermeshing gears, there is a gear as the driving wheel, and the power is input from it. Another gear acts as a driven wheel and power is output from it. …

Working of Switchgear: One of the main functions of switchgear is to keep a device, such as a fuse, switch relay circuit breaker, on and off. This allows operating devices such as electrical devices such as generators, distributors, transmission lines, etc. Once a short circuit occurs in the power system, a high current will flow from the device.

But if the further leak persists in the system, it initiates the bypass and isolation valve. Now steering gear run on 50% of its torque isolating the faulty set of rams. Rotary Vane Design: Rotary vane steering gear system works on a similar principle as of the two and four ram steering systems.

An interesting feature about planetary gearbox working principle is that, you can achieve many speed ratios from a compact and robust structure. First, I want you to understand that, the working principle of planetary gearbox involves three main components: Sun gear Planet gear Ring gear By changing the state of any of these gears, you […]

After a long, smooth flight, you have finally arrived at your destination and you hear the sound of landing gears opening up as the plane lands. The seatbelt...

The working principle of vacuum and the hydraulic clutch is almost the same. Although the significant difference between those is that, the hydraulic clutch operates through the pressure of oil, on the other hand, a vacuum clutch operates through a vacuum.

Gear Box. A gearbox is a mechanical method of transferring energy from one device to another and is used to increase torque while reducing speed. Torque is the power generated through the bending or twisting of a solid material. This term is often used …
