ABSTRACT:
A rolling contact bearing comprises a central screw 1 threaded on its outside surface and a nut 13 threaded on its inside surface. Rollers 4 are disposed between screw 1 and nut 13 and have threads that are in mesh simultaneously with those of the screw and the nut. One end of nut 13 contains an internally toothed crown 14 whose toothing meshes with pinions 5 on rollers 4. An end ring 15 is pivoted on crown 14 between two flanges 16, 17 and has holes through which pass the trunions 18 of the rollers 4. An end of each trunion 18 has a part-spherical recess 19 receiving a ball 20, the balls 20 being maintained spaced apart by a cage 21. A ring 22 having a part-toroidal rolling path 23 is located above the balls 20, and a cover 24 is threaded in an end of nut 13 and permits setting under compression the roller-nut assembly in order to eliminate any play.
