Geared universal joint 90°

A geared universal joint for connecting a pair of shafts, comprising:

• two joint forks with rotatably mounted bevel- and spur gear pairs for the positive transmission of a rotational movement at an angular offset of the pair of shafts or variable diffraction angle between the pair of shafts up to 90°,
• wherein each joint fork (4, 22) comprises a connection bevel gear (1, 25) with a coaxial recess disposed at a front of the joint fork,
• wherein in each joint fork (4, 22) a 1st bearing (3, 24) accommodates the connection bevel gears (1, 25), and a 2nd bearing (7, 19) accommodates first bevel gears (5, 21) and first spur gears (8, 18), further a 3rd bearing (11, 16) accommodates second spur gears (9, 17), which are in turn connected to second bevel gears (12, 14), and the second bevel gears (12, 14) are mutually engaged with each other via a cross-axle (13), hinged, and each are freely rotatably connected, and
• in each joint fork (4,22) the connection bevel gear (1, 25) is in mutual engagement with at least one first bevel gear (5, 21) and via a coaxial 1st bearing (3, 24) is free-rotationally connected to the joint fork (4, 22).
