Thompson coupling
From Wikipedia, the free encyclopedia
The Thompson coupling is a type of universal joint that, unlike traditional universal joints, has true constant velocity between the drive and driven shaft. It consists essentially of two universal joints assembled coaxially[citation needed] and therefore also incorporates an advantage of the universal joint, no load bearing sliding surfaces. The Thomson coupling is the first constant-velocity coupling to have this property.[1] The elimination of sliding surfaces is claimed to reduce energy losses, and improve longevity compared to constant-velocity joints.[1] According to its inventor, Glenn Thompson, the coupling uses about 8 per cent less energy than an equivalent system.[2]
The coupling has earned its inventor the Australian Society for Engineering in Agriculture Engineering Award.[3]
