A coupling is a unit employed to link two shafts together at their finishes for the purpose of transmitting energy. Couplings do not generally allow disconnection of shafts throughout procedure, nevertheless there are torque limiting couplings which can slip or disconnect when some torque limit is exceeded.
The primary function of couplings is to be a part of two pieces of rotating tools whilst allowing some diploma of misalignment or end motion or each. By watchful selection, installation and servicing of couplings, substantial financial savings can be made in lowered servicing costs and downtime.

Rigid
A rigid coupling is a device of components utilised to sign up for two shafts within a motor or mechanical system. It may be used to hook up two independent systems, this sort of as a motor and a generator, or to repair a connection inside a one system. A rigid coupling might also be added between shafts to decrease shock and use at the level where the shafts fulfill.
When joining shafts inside of a machine, mechanics can decide on among adaptable and rigid couplings. While versatile models supply some movement and give amongst the shafts, rigid couplings are the most powerful selection for precise alignment and secure hold. By exactly aligning the two shafts and holding them firmly in location, rigid couplings help to improve performance and boost the envisioned daily life of the equipment. These rigid couplings are accessible in two simple designs to suit the needs of distinct purposes. Sleeve-style couplings are the most reasonably priced and least difficult to use. They consist of a single tube of content with an internal diameter that’s equal in size to the shafts. The sleeve slips over the shafts so they satisfy in the center of the coupling. A sequence of established screws can be tightened so they touch the best of every single shaft and keep them in area with out passing all the way by means of the coupling.
Clamped or compression rigid couplings arrive in two parts and match collectively about the shafts to type a sleeve. They provide much more overall flexibility than sleeved designs, and can be used on shafts that are set in area. They usually are massive adequate so that screws can pass all the way by way of the coupling and into the 2nd 50 % to make certain a secure maintain. Flanged rigid couplings are made for heavy loads or industrial equipment. They consist of short sleeves surrounded by a perpendicular flange. One particular coupling is positioned on each and every shaft so the two flanges line up encounter to encounter. A sequence of screws or bolts can then be put in in the flanges to hold them together. Due to the fact of their measurement and toughness, flanged models can be employed to bring shafts into alignment ahead of they are joined together. Rigid couplings are utilized when exact shaft alignment is necessary Shaft misalignment will impact the coupling’s overall performance as nicely as its life. Examples:
Sleeve coupling
A sleeve coupling consists of a pipe whose bore is completed to the required tolerance based on the shaft dimension. Based on the usage of the coupling a keyway is made in the bore in get to transmit the torque by implies of the essential. Two threaded holes are presented in buy to lock the coupling in position.
Sleeve couplings are also acknowledged as Box Couplings. In this scenario shaft ends are coupled collectively and abutted from every single other which are enveloped by muff or sleeve.
