Chain Drives

The need for producing more energy increases with our rising need for commercial, industrial, and residential space. In North America including the U. In any industrial facility, turbines and motors are used to produce rotational mechanical motion to perform different kind of tasks. The industrial power transmission market works with basic power transmission open-drive products like belt drives, chain drives, gear drives and each has its own set of advantages and disadvantages. In this post, we will look into the pros and cons of these components of power transmission technology. One of the most common devices, belt drives are used to transmit motion from one shaft to another with the help of a thin inextensible band that runs over two pulleys.

A prime mover is used to generate mechanical energy by converting from other form of energy. For example, electric motor converts electrical energy to mechanical energy and delivers the same in the form of shaft rotation. Similarly, hydraulic turbine, steam turbine, wind mill, etc. Mechanical drives are used to transmit motion, torque and power from such prime movers driver shaft to machine parts driven shaft. Apart from transmission, they can also change the direction of rotation and alter the speed according to the requirement in the machine unit. There are four mechanical drives, namely gear drive, belt drive, chain drive, and rope drive. Such drives also take help of other power transmission elements like shaft, key, coupling, brake, clutch, pulley, sprocket, etc.

Both a chain drive and a belt drive are part of mechanisms that allow locomotion and a transfer of power within a particular piece of machinery. The usual application of a chain drive and a belt drive is to transfer power or as a method to move objects, like hoisting or conveying. Chain drives and belt drives are often used in many vehicles like bicycles, motorcycles, and automobiles as well as other mechanical applications, including garage doors. Both chain drives and belt drives are designed as continuous and endless loops that move when the engine is running or in use. The chain drive, as its name implies, is made up of chains with special structures like teeth on one side and a corresponding etch on the other side drive shafts.

Belt Drive. The belt drive sits in the middle of the chain and shaft, working very much like a chain drive but with a Kevlar composite belt and pulley s instead of a chain and sprockets, the ride is smooth and quiet with the belt requiring very little attention. The rubber belt sits between both the pulleys and transmits power. A nylon coating on the upper surface of the belt protects it from cracking. As friction plays the primary role in power transmission, so it is also called a friction drive. Slip can occur between belt and pulley when load exceeds the rated capacity. All are great provided you properly maintain them.

Ba-sic to power transmission design with belt drives is to maintain friction de-veloped between the belt and the sheave or pulley contact surface. Belt creep and slip — All belts except synchronous creep, but creep must be differentiated from slip. For example, a V-belt under proper ten-sion creeps about 0.

The belt is a flexible element of a mechanical system. It is used to transfer the power from one System to another System. In this, the shafts rotate in the same direction that means the direction of rotating is the same as driving and driven pulley.

Basic purpose of mechanical drive is to transmit torque, motion and power from driving shaft usually a prime mover like an electric motor to driven shaft, and also to alter the intensity, direction and speed as per the requirement. There exist several mechanical drives to fulfill varying industrial and machinery requirements. Such drives can be classified into two major categories—positive drive and non-positive drive. A positive drive is free from slippage and thus provides constant velocity ratio. Contrary to this, a non-positive drive cannot provide fixed velocity ratio due to slippage or other similar issues.

What is a belt-drive?

Джабба поднял брови. - Хорошо, это ничего не дает. Начнем вычитание. Я беру на себя верхнюю четверть пунктов, вы, Сьюзан, среднюю. Остальные - все, что внизу. Мы ищем различие, выражаемое простым числом. Через несколько секунд всем стало ясно, что эта затея бессмысленна.

 - Ему не стоило напоминать о поразительной способности Мидж Милкен предчувствовать беду.  - Мидж, - взмолился он, - я знаю, что ты терпеть не можешь Стратмора, но… - Это не имеет никакого значения! - вспылила .

На пальцах ничего. Резким движением Халохот развернул безжизненное тело и вскрикнул от ужаса. Перед ним был не Дэвид Беккер. Рафаэль де ла Маза, банкир из пригорода Севильи, скончался почти мгновенно.

Он не верил своим глазам. Немец не хотел его оскорбить, он пытался помочь. Беккер посмотрел на ее лицо. В свете дневных ламп он увидел красноватые и синеватые следы в ее светлых волосах.
