BALL STEERING SWIVEL Russian patent published in 2013 - IPC F16C11/06 B62D7/16 

FIELD: machine building.

SUBSTANCE: ball steering swivel comprises a seamless vessel (1), made integral with a cylindrical tail (2), via which the a vessel (2) is fixed to a steering mechanism rack, a finger (4) installed in a vessel (4) with a ball head (8), a thread (5), a polyhedral element (6) and an element (7) for fixation of a protective jacket, and also an insert (9) placed on the ball head (8). The insert (9) is made of a polymer composite material characterised by good resistance to wear and high anti-friction property. On the external cylindrical surface of the tail (2) there is at least one groove (10) in the direction parallel to the axis of the vessel (1) symmetry, stretching onto a flat end support surface of the vessel (1). Grooves (10) have alternating area of a profile along the groove length (10).

EFFECT: provision of effect of groove self-cleaning in a ball swivel, which considerably increases reliability of swivel operation and steering mechanism operation in general, lower labour intensiveness of a swivel dismantling process during disassembly of a steering mechanism, eliminates potential hazard of threaded joint operability loss and damage of a swivel vessel during disassembly of a steering mechanism.
