Key Features

  • Single beam coupling for use in angular, parallel, and axial misalignment scenarios requiring zero backlash
  • Aluminum for less weight and quicker response time than stainless steel
  • Clamp mounting style installation helps increase positioning accuracy
  • Single-piece coupling for longer service life than couplings with moving parts
  • Operating temperatures up to 200 degrees F

Product Description

This Lovejoy aluminum clamp style single beam coupling is intended for use in angular, parallel, and axial misalignment scenarios requiring zero backlash and less weight and quicker response time than a stainless steel coupler has. Beam couplings, a type of flexible coupling, use one or more spiral slots cut in a single piece of metal rod to form a "spring" center section, referred to as a helical coil or beam. The beam portions of the coupling flex to accommodate misalignment while continuing to convey power between the attached shafts. This beam coupling corrects angular misalignment up to 5 degrees, parallel misalignment up to 0.005", and axial motion up to 0.010". This beam coupling's clamp-style mount can be installed or replaced without moving the shafts, which eases installation. Its single-piece construction provides longer service life than couplings with moving parts. The aluminum coupling is resistant to corrosion and can operate in temperatures up to 200 degrees F. This Lovejoy clamp style single beam coupling is suitable for use in light duty applications such as coupling a servo motor to a lead screw in a motion control system.

Flexible couplings are used to link two rotating shafts that are not aligned in order to transmit the rotational power, known as torque, from one shaft to the other. Most flexible couplings consist of two hubs and a middle assembly; each hub attaches to a shaft while the middle assembly flexes between the hubs to accommodate the misalignment of the two shafts. Shaft misalignments are generally either parallel or angular and cause complications to transmitting rotational power from one shaft to another in the form of stresses, loads, vibrations, and other forces, which vary from one type of misalignment to another. Flexible couplings are used in a broad range of applications, such as in motor vehicles, conveyors, escalators, agricultural, forestry and mining equipment, aeronautics, robotics and space exploration, among others.

Lovejoy manufactures flexible couplings, universal joints, variable speed drives and various other transmission and mechanical power products. Their products meet the standards of the International Organization for Standardization (ISO), the Deutsches Institut für Normung (DIN), the American National Standards Institute (ANSI), the American Gear Manufacturers Association (AGMA), the Society of Automotive Engineers (SAE) and Japanese Industrial Standards (JIS) for quality assurance. The company, founded in 1900, is based in Downers Grove, IL.
