- What is Lovejoy known for?
The Lovejoy brand is recognized around the world as the premier supplier of flexible shaft couplings and other power transmission components. Lovejoy is the best of the best when it comes to coupling, power transmission, hydraulic components, and tensioning and vibration management technology.
- Why use a Lovejoy flexible coupling?
A flexible coupling connects two shafts, end-to-end in the same line, for two main purposes. The first is to transmit power (torque) from one shaft to the other, causing both to rotate in unison, at the same RPM. The second is to compensate for minor amounts of misalignment and random movement between the two shafts. Belt, chain, gear, and clutch drives also transmit power from one shaft to another, but not necessarily at the same RPM and not with the shafts in approximately the same line.
- What is angular misalignment in regard to couplings?
Angular misalignment is the measure of the angle between the centerlines of driving and driven shafts, where those centerlines would intersect roughly halfway between the shaft ends. Coupling catalogs will annotate the maximum angular misalignment tolerable in each coupling, and a coupling should not be operated in applications in which both angular and parallel misalignment at their maximum values.
- What constitutes axial displacement of couplings?
Axial displacement is the change in axial position of the shaft and part of the coupling in a direction parallel to the axial centerline. It can be caused by thermal growth or a floating rotor. Some couplings are designed to limit this particular type of displacement, and are called limited end float couplings.
- What is a fail-safe Lovejoy coupling?
A fail-safe coupling is one that will continue to operate for a period of time after the element that transmits torque has failed. This is a characteristic of couplings in which some portions of both halves operate within the same plane, allowing direct contact between them.
- What are the advantages of using Lovejoy compression couplings?
Generally speaking, compression type couplings offer two advantages over shear types. Firstly, because elastomers have higher load capacity in compression than in shear, compression types can transmit higher torque and tolerate greater overload. Secondly, they offer greater torsional stiffness, with some designs even approaching the positive-displacement stiffness of metallic couplings.
- Are jaw couplings compression type couplings?
Yes, jaw couplings are a classic example of compression style couplings, initially patented in 1927. This type is still one of the most widely used types of flexible coupling, and one available at the lowest cost.
- What are typical applications of jaw couplings?
Typical applications for jaw couplings include pumps, gearboxes, compressors, fans/blowers, mixers, conveyors, and generators, usually driven by an electric motor. Jaw couplings usually are not recommended for engine-driven, frequent stop-start or reciprocating loads because they are not designed to dampen torsional vibration.
- What is an L type coupling?
An L type coupling is the industry’s standard shaft coupling type, and they accommodate for angular and parallel shaft misalignment. This coupling type also comes in the industry’s largest stock selection available, and is resistant to oil, dirt, sand, moisture, and grease.
