Bearing Assembly With Inner Race Having One or More Flats

Номер: US20180003217A1
Автор: Andrew Carter, Majid Vigeh, Vivek Chopra
Принадлежит: Rexnord Industries LLC

A bearing assembly includes an outer race and an inner race. The outer race has a body extending between a pair of axial faces and defines a radially-inward facing bearing surface. The inner race is received in the outer race and has a radially-outward facing bearing surface that bears against the radially-inward facing bearing surface of the outer race. The radially-outward facing bearing surface has one or more flat surfaces removed from it. These flats on the inner race can reduce the dimensional entry requirements for insertion of the inner race into the outer race and either permits the receiving slots in the outer race to be reduced in dimension (thereby relatively thickening the wall of the outer race, which structurally strengthens the outer races) or permits the receiving slots to be eliminated altogether.

A roll device as a spreader roll has a rotating hollow roll tube which at the ends thereof is rotatably mounted by means of bearing ends which are mounted in rotary bearings. The roll device has a tension element which runs so as to be eccentric to the central longitudinal axis of the roll tube through the roll tube and by internal tension toward the ends of the roll tube is impinged by a force with pressure. As a result, the roll tube is capable of being bent by way of an impingement of the tension element with a force, the deflection being transversely away from the longitudinal extent of said roll tube, if the tension element is tensioned in relation to the roll tube in an axial direction.

The invention relates to an umbilical termination assembly for terminating a cable or umbilical. The termination assembly comprises a plurality of umbilical elements extending from an umbilical and which pass through a bulkhead plate. The seated ball element has a spherical body through which an umbilical element passes. The ball element is seated in a cup member which allows the ball element to rotate through a large range of angles allowing it to be aligned with the umbilical element without the umbilical element needing to be manipulated or forced into position. The umbilical element can then be attached to the ball element which is supported by the cup member on the bulkhead. This allows the axial tension in the umbilical element to be transferred to the bulkhead.
