| Lovejoy offers a variety of designs and models in its gear coupling family. From standard, off-the-shelf stock to new, high speed, special designs, Lovejoy can satisfy your gear coupling needs. The original Continuous Sleeve, or “C” coupling, offers a lightweight, compact, and simple design without compromising torque carrying capacity. The Flanged Sleeve, or “F” coupling, is available in exposed or shrouded bolt styles in which the number of bolts, size of bolts, and bolt circle are identical with industry standards. The nylon sleeve gear couplings, Nyflex and Mite, are compact, lightweight couplings that use a nylon sleeve and two sintered iron hubs. Lubrication is not required with the nylon sleeve. Lovejoy also has an All Metal Labyrinth Seal coupling and an Alloy Steel coupling. The All Metal Labyrinth Seal coupling is a flanged sleeve style, but uses no elastomeric seals. The Alloy Steel coupling is made from AISI 4140 steel. |

The size of the coupling should be selected so that the nominal torque is greater than the highest torque to be regularly transmitted. (Acceleration or load torque). The shaft misalignments must not exceed the previously mentioned values. Otherwise this will limit the working life of the coupling. |

Metal bellows couplings:
- high torque range
- high torsional stiffness
- high temperatures
- patended connection method
- high speed |
|
| The perfect servo coupling - Low cost | Plug-in type, variable bore diameters | Larger shaft misalignment compensation capability | Minimal mass moment of inertia |
|
Precision motion control applications require mechanically tight systems, especially between motors, driven loads, and feedback devices, to ensure accurate positioning. Such systems often require shaft couplings that are both torsionally rigid, to accurately transmit rotational position and laterally flexible to accommodate shaft misalignment.
Servometer couplings exhibit both low windup due to the bellows' radial rigidity, and low side thrust due to the bellows' lateral flexibility. Other coupling types have either low windup or low side thrust, but not both.
Since the flexible element is a bellows, the coupling can absorb parallel shaft misalignments of 0.068 in., angular misalignments as large as 31°, or axial movements of 0.230 in. while transmitting torque. Servometer's stock lines of flexible shaft couplings are available with stainless steel hub bore diameters ranging from .079 in. (2 mm) to 1.0 in. (25.4 mm), and with torque capabilities ranging from 2.0 in-oz (1.4 N-cm) to 4000 in-oz (2825 N-cm). Outside diameters range from 0.250 in. (6.35 mm) to 2.40 in. (61 mm) and overall lengths from 0.480 in. (12.19 mm) to 2.16 in. (54.9 mm). Specialized dynamic requirements can be custom designed to fit customer specifications.
Some unique characteristics of Servometer bellows-type flexible shaft couplings are:
- Extremely low elastic windup
- Zero backlash
- Zero cyclic speed variation during 360° rotation
- Minimal side loading
Typical applications include:
- Encoders
- Resolvers
- Servos
- Motion control instrumentation
- Robotics
- CNC machine tools
- Precision positioning |

These torsionally stiff couplings serve for the connection of two shaft ends compensating for angular and parallel misanlignment as well as axial backlash. They are used for the backlash-free and precise angular drive of:
-potentiometers / angle encoders
-resolvers / transducers
-low powered drives
The mounting of the coupling onto the shaft ends is achieved by two set screws each with one cup point per hub. In the case of a smaller than indicated size of bore, an accurate transmission or peak-torque is no longer guaranteed. Larger borings can be supplied on request. |
