This process of transmission is fairly imperative in various operations of numerous machineries. There are many power transmission equipments such as pulleys, Industrial Couplings, speed reducers, conveyor belts, transmission chains, gearboxes etc. Coupling is a piece of equipment used to join two shafts together at their ends, in order to conduct transmittiion of power. Normally Industrial Couplings does not allow shafts to disconnect during the process, but there are torque restraining couplings that may slide down or get disconnected, in case torque limit is surpassed. This sliding can be avoided, by selecting, installing and maintaining the couplings carefully; this is also lead to considerable savings and reduced maintenance costs and downtime. There is a variety of flexible Industrial Couplings available with different functionalities and purposes. Another, important power transmission equipment is the Cleated Belt Conveyor.power transmission power transmission equipments power transmission Transformer Oil Vacuum Dehydration And Purification Posted By: oilfiltration The primary function of vacuum dehydration and purification is to remove free, emulsified, and dissolved water from oil, as well as solid particulate contamination.

The gas generator that was used to run Boeing 747s and other aircrafts, were also used in power turbines for compressor, general applications and mechanical drive. Gas turbines are special functional machines that require special functional couplings. Generally, the special functional or special purpose machines are divided into high-powered and high speed. The usual horsepower is more than 1000 and the speed is above 3000 rpm. About the use of gear couplings in gas turbines Gear couplings have been in use for a long time to couple critical equipments. They are mostly chosen for critical equipments for their high power density. It provides more horsepower per weight pound and cubic inch of space. Because they are rough and even, they can withstand any type of beating coming from starts and stops or torque spikes. If properly lubricated, these equipments can last for several years. Gear couplings are used in gas turbines between the turbine and its driving item, be it a compressor, pump, gear box or generator.gear couplings gear couplings Posted By: BraydenBaker Rubber Bellows act as extension joints of rotating gears like pump, pipe works and chillers. They are highly flexible and hence fit easily to complete some misaligned installation allowing lateral, axial and angular movement. This is very similar to metal extension joints. These Bellows are also thin walled which isolates noise and vibration to the optimum. Rubber Bellows are extensively used in Fluid Filling System, Chemical Plants, Hydraulic Ram Protections and adjustments in the Duct line. Rubber being an unrefined compound has a limited life. External forces like temperature, ozone, ultraviolet light etc. hampers the bellows a lot. With these influences at work, the Bellows change their shape under high temperature and pressure. To reduce the expansion of the Bellows, the pipe works must be anchored. Components and Features of Rubber Bellows The Rubber Bellows are manufactured from Rubberised Canvas, Rubber, Rubberised Synthetic Fibres and many stiffeners to strengthen it to resist pressure. Even the rubber-molded Bellows are at times made of various types of Polymers, like Silicone, Neoprene etc. The Bellows can be compressed into many shapes like round, square and rectangle, depending upon the length desired.rubber bellows extension bellows bellows expansion joints rubber bellows A Complete Guide To The Different Causes Of Misalignment Of Gear Couplings Posted By: BraydenBaker In order to meet different requirements, various types of mechanical devices are being used in applications. Gear couplings is such a mechanical device that comprises two shaft hubs with external teeth and are connected with the help of sleeve, mainly of two pieces with internal teeth. Gear couplings can fix shafts of two different machines and can also adjust shaft alignments in small amounts. The coupling works like that of a flexible spline with hubs and sleeves rotating jointly. Generally, commercial couplings pass on more torque because of the huge physical size as compared to other types of couplings. Due to their load transmitting capability, these are widely used in high speed applications as well as on applications that requires high torque capacity coupled with low inertia of the drive system. Misalignment and failure Just like other machines are mechanical devices, gear couplings too can suffer failure from various causes. There are three types of misalignment that takes place in general -combination misalignment, parallel offset misalignment and angle misalignment. Here are some of the cause of misalignment and failure: -Misalignment wear is one of the causes of failures of gear couplings.gear couplings mechanical devices angle misalignment offset gear couplings Everything You Wanted To Know About A Thruster Brake Posted By: BraydenBaker The first thing you know about a thruster brake is that it is a machine that is used to hold back the speed of moving mechanism and to stop it in the required position. There is a pre-stressed comprising spring that applies a braking force to the brake shoes. The thruster releases the break drum and compresses the spring. Assembly of a thruster brake A thruster brake consists of cast iron shoes that are lined up with friction pads. Each shoe has a pivot fitted in the base and are situated on the main arm side arm of the brake. They are connected with each other by tie rod on the top which is locked in the swivel block in the side arm and pivoted to the main arm by a lock nut. There is a crank liver that is hinged on the main arm, whereas the other end is attached to the top clevis of the thruster with the help of a hinge pin. There is also a brake spring connected to the main arm and a locknut pre-loads it on the lever.thruster brake thruster brake Everything You Wanted To Know About Flexible Gear Couplings Posted By: BraydenBaker Gear couplings are mechanical device used for power transmission and use a hub with gear teeth on the outer diameter of the input shaft. The hub on the output shaft is joined by a sleeve or flange with the teeth found in the inside diameter. This helps to transfer the torque as well as house shaft misalignment. Gear couplings are generally made of metals and so, they really need proper lubrication for a problem free running. These couplings are generally very rigid and can transfer high torque via small packages. What does a coupling comprises of Gear couplings consist of a clutch with an input connection to power take off and an output to transfer power input of trailer unit. The tension generated as the coupling joins the trailer units and tractor is generally monitored and the clutch slippage in also controlled in reaction to monitored tension. This monitoring is needed to regulate the speed of the trailer unit which is same as the speed of the tractor unit. About flexible coupling Flexible coupling joins rotating members like drive shafts and motors as well as allow misalignment in either parallel or angular offset orientation.gear couplings gear couplings Are You At Risk Of Gear Coupling Failures? Posted By: BraydenBaker Gear couplings are mechanical devices used to join shafts of two different machines. Commercial gear couplings are best for more torque transferring due to their size. Gear couplings are widely used in high speed applications for their high load transmitting capacity in applications that require high torque capacity. Gear couplings have two shaft hubs with external teeth that are connected with sleeve of two pieces containing internal teeth. A gear coupling works like flexible spline that has sleeves and hubs moving together. Proper lubrication of the right type is required to help the gear couplings work properly. Since, gear couplings are mechanical devices; they are subjected to failures as well. So, here we will discuss the different causes of failures of gear couplings: Failures due to lubrication Adequate maintenance of lubrication is extremely important for the proper working of gear couplings. It has been found that the lack of lubrication is the primary cause of failure of gear couplings. When there is loss of lubrication between the external and internal teeth, the surface rubbing against each other leads to breakage of small metal particles. In some rare cases, you can also find fretting corrosion.gear couplings gear coupling failures coupling failures g gear couplings Tips To Extend The Life Of Your Gear Couplings Posted By: BraydenBaker gear couplings good quality speed gear couplings performance gear couplings A Brief Guide On The Different Types Of Gear Couplings Available Posted By: BraydenBaker Couplings are used to attach two shafts at their ends. Precisely, these are mechanical devices that are used to transmit the torque in between the two non-coaxial shafts. Generally, gear couplings include a flexible joint that is joined to each of the shafts and there is a third shaft known as spindle which fixes the two joints. Well maintained and properly functioning gear couplings are very important for better performance of gears. Well designed gear couplings are expected to take in the misalignment forces, thus saving some of the most important components from any kind of harm. A gear coupling generally includes a clutch with an input connection. The tension generated when the coupling connects the trailer and tractor units and the slippage of the clutch is well controlled in answer to monitored tension. This is very important to maintain the speed of the trailer unit when it is driven which is more or less same as the speed of the tractor unit.gear couplings gear coupling types flexible couplings gea gear couplings Lubricating Gear Couplings – A Complete Guide Posted By: BraydenBaker If you want to increase the life of the gear couplings in your machine, then proper lubrication is the only way. Remember, periodic lubrication is the secret to long lasting couplings. However, choosing the right lubrication is also important and the principles of lubricant properties and gear wear should be kept in mind too. The advantages and disadvantages of gear couplings Before you get to know about the right kind of lubrication needed for gear couplings, you must know the advantages first. Some of the advantages of using gear couplings are: -Gear couplings can send more power per inch of diameter and per pound than any other coupling. -Even if you mishandle them or improperly install them, gear couplings will go on giving satisfactory service -They are safer and consistent -The only disadvantage is wearing of the teeth, which takes place gradual in process. Complete worn out of the teeth will only result in power loss. How does a lubricant work on gear couplings? The force generated by mating teeth along with the oscillatory motion generally wipes off the lubrication from the surface of contact.gear couplings lubrication gear coupling lubricating gear gear couplings Energy Generation Equipments – Why There Is A Surging Demand In The Market!
