Lovejoy coupling size chart

The goal of this handbook is to assist you with lovejoy coupling size chart process of sorting out the myriad of coupling styles that exist to select the one best suited to your application. This handbook is not a textbook. There are several of those in print which do a great job and are very useful for coupling designers. What we are attempting to do is to provide down-to-earth useable knowledge.

Safety Warning When using Lovejoy products, you must follow these instructions and take the following precautions. Failure to do so may cause the power transmission product to break and parts to be thrown with sufficient force to cause severe injury or death. Refer to this Lovejoy Catalog for proper selection, sizing, horsepower, torque range, and speed range of power transmission products, including elastomeric elements for couplings. Follow the installation instructions included with the product, and in the individual product catalogs for proper installation of power transmission These couplings require no lubrication and provide highly reliable service for light, medium, and heavy duty electrical motor and internal combustion power transmission applications. Lovejoy offers four types of elastomer designs to allow for additional flexibility in addressing specific application requirements. The load cushions are in sets of 6 to 14 pieces depending on coupling size.

.

Oil and soaps separate in ordinary lubricants because of centrifugal forces on the heavier particles. The centerline of the projection or motion normally passes through the axial centerline of the object. Rotating equipment shafts are often oversized because they are designed to limit deflection, which can lovejoy coupling size chart to oversize couplings.

We want to arm you with information that you need to utilize the variety of styles that exist in flexible couplings to your best advantage and solve real world problems. Lovejoy has been manufacturing couplings since

The first is when the BE dimension is very small and coupling hubs need to be installed further back from the shaft ends. It is not necessarily a high voltage insulator as found in wiring systems. Disc 28 Pages. When the flex hub is on the center shaft it is called a marine style coupling. SET SCREW: A headless screw, with hexagon shaped socket, used over a keyway to keep the key stock in place and prevent the coupling from moving axially along the shaft. In general, the shear type donut coupling will work well on electric motor driven applications with uniform loads such as; centrifugal pumps, blowers and fans, screw compressors, some conveyors, line shafts, and vacuum pumps. Removal also is accomplished by hydraulic pressure. The body fit bolt has a tight fit to the bolt holes that keep the two halves concentric. Each component or piece of the coupling could be subjected to a balancing procedure on a balancing machine. The donut style elastomeric coupling is primarily used on torsional damping and tuning systems associated with Diesel drivers. Example: Sliding the hub in either direction may change the position of a coupling hub, on its shaft. There are several methods to fasten the hub to the shaft. Having the shaft hub slide into the flywheel attached elastomer does this. Everything is built for speed, which means small, light and precise.

Each hub includes a set screw unless noted , which bites into your shaft to hold the coupling in place. A complete coupling consists of two hubs and one spider, or two hubs, one split spider, and one retaining ring all components sold separately.

Everything is built for speed, which means small, light and precise. When two halves of a flanged sleeve are bolted together, the bolting becomes an important part of the power transmission path. High Speed Gear Couplings. HercuFlex Couplings Catalog 28 Pages. With all these advantages the gear coupling is used on twice as many applications versus the nearest competitor type. Elastomers for Donut Type couplings. S-Flex 22 Pages. Of course, to make this work, the shaft keyway must also be aligned with a significant part of the machinery. It also allows a single flex plane to accommodate both angular and parallel misalignment. Torsional 42 Pages.
