Couplings are used in every facet of machinery; they are a device that is used to connect two shafts at their ends to create and transmit power. They stay connected while in operation, but some types of torque connecting can slip or disconnect if the limit is exceeded. The basic use of these devices is to join together these two pieces of rotating equipment while allowing for movement for both pieces. Choose the right type of devices and you can reduce your maintenance costs and limit downtime.
There are many uses for these shaft couplings. They provide connection for units that were originally created separately, like a motor and generator; they provide for easy connection and disconnection in the case of repairs and maintenance. These connections provide mechanical flexibility, as well as a reduction of shock loads from one shaft to another. Connections of this sort will protect against overloads of weight, as well as too much vibration.
There are a few different types of couplings, rigid, flexible and torque limiting setup. Each type is used for a different project. Rigid units join two shafts within a motor or mechanical system. Flexible units are used to pass torque from one shaft to another when they are slightly misaligned; they are used for noise reduction as well. Torque limiting connections will work with a chain joint that will prevent over loading. If you have more questions, speak with these trusted resources.
