subject: Learning The Basics Of Coupling From Gear Coupling Manufacturers [print this page] Couplings are mechanical devices which are used to connect the two shafts at their ends to achieve some mechanical purpose. Whether the coupling will get disjointed during the operation or not will depend on the precise purpose for which these are to be used. For example, the gear coupling manufacturers use these devices to transfer the torque between the two shafts that are not collinear. The use of these devices could be done in situations where there is a requirement of some movement or misalignment at the ends.
Types of Couplings
These are of two basic types: rigid and flexible. The rigid ones are those which are used to join two shafts either within a machine such as motor or within a system such as a motor and a generator. The use of the rigid ones is done in those situations where there is a requirement of firmly securing the system and precise alignment is required to be done between the two connecting shafts.
The flexible couplings are those which are used to make connection in a slightly misaligned manner. However, this misalignment is precise to a certain level of degree only, as per the requirement of the machine but not exceeding 3-5 degrees in most of the cases. Another major use of these by the gear coupling manufacturers in India is to create high backlash (called as- play- in common parlance to denote certain lose of motion while the reconnection is established between the movements of mechanical devices such as automobiles). Besides the gear, the flexible couplings could be of types beam, diaphragm, fluid and many others.
Applications of the Gear Couplings
Some of the most common applications of the flexible gear couplings made by the gear coupling manufacturers in India are used in conveyors, elevator drives, industrial fans, air compressors, cement mills, EOT cranes, rolling mill drives and in the mining machinery. The gear coupling is believed to have the highest torque capacities as compared with any other flexible coupling which makes these suitable for heavy industry applications.
The couplings need regular maintenance but not too much. While checking these, there shall be focus on proper lubrication and wear and tear. Sometimes, you can also make out the problem with the coupling with the sounds which it generates such as that of screeching or chattering, or even with the noticeable wobbling which it creates. By paying attention to the problems or ignoring these could result in inefficient operation and also in mechanical failure leading to some major accident.
