EC Series, Single Beam Clamp Style Couplings, Metric Bores
Motion control beam couplings are flexible couplings that use either one or more spiral slots cut in a single metal rod piece, thereby forming a spring centre section known as a beam or helical coil. The beam portions of these couplings flex for accommodating misalignments while continuing to transfer power between the attached shafts.
Lovejoy aluminium clamp style single beam couplings are designed for parallel, angular & axial misalignments of shafts requiring less weight & zero backlash. Lovejoy clamp style single beam couplings are recommended for use in light duty applications such as coupling a servo motor to a lead screw in motion control systems.
These single beam couplings have quicker response time as compared to stainless steel couplers. These beam couplings accommodate parallel misalignment up to 0.005 inches, angular misalignments up to 5 degrees and axial motion up to 0.01 inches. These clamp-style beam couplings can either be installed or replaced without the movement of shafts. These Lovejoy single beam couplings feature single piece construction with anodised aluminium finish to provide longer service life in comparison to couplings with moving parts. They are resistant to corrosion and can be operated at a maximum temperature of 200 degrees F.
Flexible power transmission couplings such as Lovejoy beam couplings are suitable for operations where there is some acceptable misalignment. These helical couplings can accommodate parallel offset, axial motion and angular misalignments between two shafts. These aluminium couplings are ideal for operations where a high level of responsiveness is required. Lovejoy beam couplings are suitable for light duty power transmission applications in medical equipment, imaging tools, lab analysis, encoding machines, small pumps, drives, motors and tachogenerators. These single beam style couplings are also used for machining, instrumentation and various motion control & automation applications.
Lovejoy beam couplings are designed from a single, solid piece of aluminium rod. These single beam style couplings have spiral slots throughout the length of the coupling. During power transmission, the spiral slots of these beam couplings adjust automatically for accommodating various parallel offset, axial motion and angular misalignments between two shafts.
Frequently Asked Questions
What are the early symptoms of excessive wear in couplings?
Some external signs which indicate potential coupling failure include abnormal noise, such as squealing, screeching or chattering; failed seals due to lubricant leakage or contamination; and excessive wobble or vibration.
What are the different types of couplings offered by Lovejoy?
Straight jaw type couplings
- Curved jaw type couplings
- Gear type couplings
- Grid type couplings
- Disc type couplings
- Torsional type couplings
- Specialty type couplings
What are the requirements of a good shaft coupling?
It should be easy to connect and disconnect.
- It should transfer full power from one shaft to the other without torque loss.
- It should hold the shaft in accurate alignment.
- It should minimise transmission of shock loads.
- It should not have have any projecting parts.
What is the difference between rigid and flexible couplings?
Rigid couplings offer a rigid connection between two shafts that are firmly connected, and facilitate the coupling to transfer torque smoothly throughout the system. Flexible couplings provide flexible connections, and there is a chance of losing some torque during transmission.
What are the advantages of flexible couplings?
Flexible couplings have an advantage over rigid couplings owing to the unavoidable misalignment between shafts in the machinery. In a flexible coupling, movement between the shafts is possible as a result of thermal expansion.
