Lovejoy Grid coupling reduces vibration by as much
as 30%, and cushions shock loads to safeguard your
driving and driven equipment. The flexible nature
of the spring-like grid absorbs impact
energy by spreading it out over time, thus reducing
the magnitude of the peak loads. This is possible
because of the progressive contact that occurs between
the curved profile of the hub teeth and the flexible
grid. Therefore, as the load increases, more of the
tooth comes into contact with the grid, thus supplying
superior protection and supreme performance.
Lovejoys Grid couplings are designed for versatility. Common hubs and grids are used within a given size range for both horizontal and vertical split cover models. Grid installation and replacement is a snap at only a fraction of the complete coupling cost.
Top Quality Manufacturing Made from high tensile alloy steel, the grid spring is carefully formed to shape, then hardened and tempered under controlled conditions. Next, the grids are shot-peened, compressing the surface molecules and leaving a residually stressed surface. This process creates a stronger surface in compression.
Any load applied on the coupling in operation must first surmount the compressive forces created by peening before the tensile stress reaches the grid. This provides a dramatic increase in rating over other coupling types, increases reserve strength for longer life and may permit selection of a smaller coupling, thus reducing cost.
