Lovejoy is pleased to be able to provide quality grid couplings covering a
large number of industry standard sizes and lengths. The Lovejoy grid style
coupling has proven itself in performance and popularity over a wide range
Lovejoy’s grid style coupling design has demonstrated its ability to dampen
vibration by as much as 30% and can cushion shock loads that could cause
damage to both the driving and driven equipment. The tapered grid spring
design absorbs impact energy by spreading the energy out over the full
length of the grid spring thus reducing the magnitude of the torque spikes.
The Lovejoy design uses a curved hub tooth profile which creates a
progressive contact with the flexible grid spring as the application torque
increases. This feature provides a more effective and efficient transmission
of power in properly aligned couplings.
Lovejoy’s versatile design of industry standard hubs and grid springs
for both horizontal and vertical cover styles allow Lovejoy couplings
to be interchangeable with other industry standard grid couplings and
Proper grid coupling installation and maintenance can add to a longer
coupling life. Grid spring replacement is simple and can be performed at a
fraction of the cost and time of a complete coupling.
The Lovejoy Grid coupling is an ideal coupling for
applications where excellent performance is desired and
additional requirements for vibration dampening may
exist. The Horizontal Split Cover design is recommended
in applications where there may be some constraints
on the diameter of the coupling. The vertical design is
recommended for applications where higher speed is one of
- Designed for ease of maintenance and grid spring replacement
- High tensile grid springs ensure superior coupling performance and longer coupling life
- Split covers allow for easy access to grid springs
- Interchangeable with industry standard grid couplings
