Flexible coupling have many advantage such as it can take up misalignment, it can dampen vibration, it is easy to install and it is low cost. However, the disadvantages of flexible coupling are that it have a shorter life span compare to rigid coupling, it is not suitable for high speed application and it can not take up much radial load.
Flexible coupling have several disadvantages which include: 1. They are not as strong as rigid coupling and thus are not suitable for heavy duty applications. 2. They are more expensive than rigid coupling. 3. They are not as accurate as rigid coupling and thus are not suitable for precision applications.
Flexible couplings are used to connect two shafts together and transmit torque while accommodating for misalignment. There are three common types of flexible couplings: compression, expansion, and universal. Compression flexible couplings work by press-fitting two hubs together with a central sleeve. The sleeve is usually made of metal or plastic and is perforated to allow for even distribution of pressure. This type of coupling is often used in small applications where precise alignment is not required. Expansion flexible couplings work by inserting a sleeve between two hubs and then expanding the
Couplers are devices used to join two pieces of equipment or connect two sections of pipe or tubing. There are three basic types of couplers: 1. Slip couplers have a smooth inner surface that allows them to slide over the ends of the pipes or tubing being joined. A slip coupler is held in place by the pressure of the fluid passing through it. 2. Threaded couplers have threads on the inner surface that match the threads on the ends of the pipes or tubing being joined. Threaded couplers are tightened by hand

It was simpler to order new shaft couplings than to adapt the ones that came with my CNC router kit since the previous ones were the wrong size. Amazon claimed to deliver these by Monday when I placed my late Friday order, but they arrived on Sunday. Gotta adore that Prime delivery from Amazon! I had some concerns based on some of the other reviews, but the quality was superb. These shaft couplers work well with motor shafts that have 0, 1, or 2 flats since they each have four set screws, as seen in the figure. Having previously experienced slipping shaft couplers and being aware of the hassle that can result, I already fitted the stepper motors and torqued the heck out of them. There were no stripped set screw heads or holes in the tapped aluminum. For these set screws, a 2mm hex key is required. Industrial suppliers' comparable shaft couplers cost more than three times as much.

The collet-style connection is quite functional and well manufactured. Just remember to back out the set screw before tightening the collet clamp bolt. For my use, I must drill the 12mm end to 1/2 inch (12.7mm). I turned this on a lathe. The coupler was thrown into my lathe, and I was able to measure the run-out, which was less than.001 inch. nice stuff

These came in the 6.35 x 6mm size, and I ordered 2. Despite coming from the same business, they were sold on two different Amazon pages due to their about $0.60 price difference.I got my first one from the other page yesterday, and it was great. The fit and finish were simply amazing. similar to a work of art.I received the second one today, and it appeared to have been fabricated by some high school students using a hacksaw and rough files. It appears awfully horrible! It is in good condition except from the need to slightly file one end to fit the shaft because it appears to have been dropped. It is perfect in terms of dimensions and usefulness, but it just looks awful (which is OK for my use)It's the distinction between a piece that was turned using good, crisp tooling and a piece that was made using old, worn out tooling.If the part's looks are significant to you, cross your fingers since you have a 50/50 chance. If appearances are not that essential to you, you'll still be happy because these are cute little couplers. Particularly for the cost!Good fortune.Jim

The set screws came out a couple times despite being well manufactured. If the factory-installed screws had some loctite (or a comparable product), I would have given it five stars. It appears that some oil leaked down the lead screw (which will happen!) and loosened the set screws, which eventually caused them to come loose. Being a petrolhead myself, I also have a ton of Loctite Blue (like http://a.co/db5wfxL) lying around, so the product is now fine.

There are many types of flexible coupling, but the most common are: -Bellows coupling: These consist of a series of metal bellows that allow for axial, angular, and sometimes radial movement. -Disc coupling: These have two hubs with a series of flat discs in between that act as flexible elements. -Diaphragm coupling: These have a flexible diaphragm that is sandwiched between two hubs. -Elastomeric coupling: These have an elastomeric element (usually rubber) that connects the two hubs
There are many types of couplers available on the market, each with its own advantages and disadvantages. The type of coupler that allows the greatest flexibility is the ball and socket coupler. This type of coupler allows for a wide range of movement, making it ideal for use in applications where a high degree of movement is required.
A beam coupling, also called a rigid coupling, is a device used to connect two shafts together while allowing for some degree of misalignment or end play. The coupling consists of two hubs that are connected by a central member, typically a beam or bar. The hubs are connected to the shafts using set screws, keys, or other fasteners.
A bellows coupler is a device used to connect two shafts together while allowing for axial movement between them. This type of coupler is often used in applications where one shaft is driving another, such as in a gearbox, and the axial movement is needed to compensate for misalignment between the shafts.
A flanged coupling is a device that is used to connect two pipes or other cylindrical objects together. The coupling consists of two halves, each with a flange (a flat ring with holes in it) that is bolted together with bolts.
A helical coupling is a device that is used to connect two shafts together. It is a type of coupling that uses a helical gear to transmit torque between the two shafts. Helical couplings are typically used in applications where high torque needs to be transmitted between the two shafts, such as in a gearbox.
