MERITT Flexible Gear Coupling has teeth of involute flanks, and faces curved in both directions, so that they are able to accommodate anguler misalignment by a ball and socket action. Flexibility is obtained by play between the teeth.
MERITT Flexible Gear Coupling gear improves the fit, result in smoother and quieter operations, and offers long service life with minimum maintenance. It also provide high power / size ratio. Lubrication is provided by heavy oil, enclosed in a dust and grit-proof casing and distributed over the gear teeth by centrifugal action. The large area of lubricated surface also cushions shock and permits fairly high-speed operations.
Full geared coupling accomodated both parallel offset and anguler misaligment.... or a combination of the two, as well as end float.
