SWIVEL JOINT Russian patent published in 2012 - IPC B60N2/225 F16H1/32 

FIELD: transport.

SUBSTANCE: in the swivel joint, the first gear (1) is rigidly installed on one turning unit, and the second gear (3) is rigidly installed on the other turning unit, which gears have axially oriented ring gears (2,4). The first gear (1) interacts with the second gear (3) which has number of teeth differing from the first gear through rotating epicyclic train via which the first unit is turning relative to the second unit by means of cycling. The first gear (1) and the second gear (3) are made with mutually facing ring gears (2,4) and are positioned coaxially relative to the axis (8) and forming gap (12) in which ratchet (13) is located. The ratchet (13) on both its ends also has axial ring gears (14,15) with mutually shifted division. The ratchet (13) is driven by epicyclic train rotating around the axis (8) and is rotating and cycling respectively diametrically opposite on its one end in engagement with the first gear (1), and on its other end - in engagement with the second gear (3) forming gear mesh without gap. Difference in number of ring gear (2) teeth of the first gear (1) as against mating ring gear (14) of the ratchet (13) differs from difference in number of ring gear (4) teeth of the second gear (3) as against mating ring gear (15) of the ratchet (13). Using radial epicyclic train, the ratchet (13) is biased into tilted position relative to the axis (8) while forming engagement between its ring gears (14, 15) in the first and the second gears (1, 3). Driving shaft (16) is equipped with two diametrically opposite radially oriented chain levers (19, 19') which are adjacent to the ratchet (13) in axial direction.

EFFECT: creation of swivel joint allowing high load and providing smooth rear rotation.
