V belt Drive A V belt drive is used for high power; high toque and short distance transmissions. For example power transmission from motor to pumping section of water pump (Dokey pump).  V belt get their names from the shape of their cross section as it looks like the English alpha bet “V”.  Like their cross section shape, the pulley used in v belt drive is also like English alpha bet V.  they can easily cover come the shocks introduce in power transmission system because of greater belt strength and can avoid slipping due to greater belt and pulley friction.  Flat Belt Drive A flat belt drive is used for moderate power; moderate toque and moderate distance transmissions. For example power transmission from motor to pulley of conveyer belt.  Flat belt get their names from the flat geometry and rectangle shape of their cross section. The pulley used in flat belt drive has a simple cylindrical shape.  They can easily cover come the small shocks introduce in power transmission system b

Brakes A device whose sole purpose is to make any rotating mechanism slow or stop or control it as required is called brake. Brake can generally be divided in to two main parts; one forces applying part and second force transferring part. Force taking part is one which takes force from operator and turns that force into pressure which can be applied to second part. Second part takes pressure from first part and transferring it to rotating mechanism after converting it to torque.  There are two main types of braking mechanism available  1. Drum Brake 2. Disk Brake Drum Brake Drum brakes get their name from the one of their part shape which looks like an empty drum. Drum brake usually consist of three main parts; shoes, shoes pad and drum. Drum is the part which is attached with the rotating part of the mechanism where shoes pads which are attached to shoes are attached to the hydraulic or any other force providing mechanism. When force is provided by the hydraulic

Power transmission is one of the most comment phenomena which happen in most of the mechanical powered machines.  Power transmission is the transfer of power from primary mover to the mechanism which provides the useful output.  Following are four different types of power transmission methods used in each and every mechanically powered device. 1. Gear Drive Power Transmission System 2. Chain Drive Power Transmission System 3. Rope Drive Power Transmission System 4. Belt Drive Power Transmission System Four Different Power Transmission Methods Gear Drive Power Transmission System This methods of transmitting power using gears is one of most commonly used method in vehicles where power from motor or engine is transfer to the tires using one or more gear sets.  Gear drives are mostly used in those applications where length between the primary mover and driving mechanism is very small and power or rpm value requirement at the output is fixed.  Gears used in gear drives are

One of the tasks in designing of any mechanical product like  Belt Drive Power Transmission Mechanism   is the selection of material for it.  Material selection for the belt drive is the most important task in designing of the Belt Drive Power Transmission Mechanism,  as the strength and density of the material will decide the dimensions and working parameters of the product. Material selection of Belt Drive Power Transmission Mechanism consists of follow steps 1. Product Requirements 2. Material Selection Criteria 3. Available Material Analysis 4. Final Material Selection Belt Drive Mechanism Product Requirements for  Belt Drive Power Transmission Mechanism Product requirements are based to the working of the product. They are those mechanical, physical and economical properties which are required for the effective working of the product.  For the effective working of the belts following are the mechanical, physical and economical properties which are required. 1. Tensile Stren

There is a certain design criteria and standards on which the selections of the belt derive is done.  Following is the four point criteria in which selection of belt depends IS: 2494-2017  1. Belt velocity 2. Belt contact arc 3. Belt tension 4. Belt working conditions Belt Velocity of Belt Drive Velocity with which belt moves, has a great effect on its selection because when belts moves over pulley it bears wear and tear.  So greater the velocity with belts moves over the pulley, grater will be the wear and tear.  Along with this there is certain some certain limit of velocity up to which belt can transfer power effectively and after the system does not work effectively. Belt Contact Arc with Pulley Belt contact arm with the smaller pulley has great influence on its selection because more the contact arc of the belt more of its area will face friction effects.  Greater the contact arc of belt more effectively it can transmit power from one pulley to another Belt Tension in Drive M

In most of mechanically moving item there is a mechanism installed whose main purpose in to stop the motion of that item when required. This mechanism is called braking mechanism. They are design to stop the motion of vehicle (type of motion of the vehicle does not matter) and it does so by producing friction between its components. Friction produce by the braking system uses the energy present in moving body resulting in decrease in speed of vehicle and finally stop of motion of body. Kinetic energy of vehicle which is utilized by the friction of brake is converted into heat and that heat is them move to the surrounding atmosphere. Types of Brake There are two basic types of braking system 1. Disk Brake  2. Drum Brake Disk Brake Disk brake system consists of two main parts, one is called rotor and other is called pad. Working of disk is starts when operator applies pressure on hydraulic pad of which transfer pressure to the pad of the brake. Pad of the braki

Power transfer from primary mover to any mechanism which gives some useful outcome is one of the most common works done in mechanically engineered products.  In order to transfer power form primary mover to any mechanism products like gears, belts, rope and chains are used.  These products transfer power from one place to another and also can provide mechanical advantages in terms of increase speed or torque at output.  From the above mention products belts are one which can be used to transfer power from primary mover to mechanism when primary mover and mechanism is far apart and light weight power transfer mechanism is required.  Belts have the ability to effectively transfer power even when primary power and mechanism are even meters away from each other.  Flat belt vs V-belt drive What is a Belt Power Transfer System? Belt power transfer mechanism consists of at least two pulleys (from which one is attached to shaft of primary mover and second is attached to input shaft of mec
