Abstract
A non-rotating sleeve type bushing in which an eccentric flange integral with the bushing and projecting radially outwardly therefrom is so formed as to be received in a complementarily contoured flange recess in a bearing housing whereby rotation of the bushing with respect to the bearing housing is precluded by a positive mechanical locking action provided by the shear resistance of the flange member.
Claims11
A non-rotating sleeve type bushing, said bushing including, in combination,
- a sleeve, said sleeve having
- an exterior surface formed and adapted to be received in a suitable receptacle, such as a bearing housing, and
- an interior surface formed and adapted to receive a rotating member, and
- a flange member,
- said flange member being integral with the sleeve,
- at least one protion of said flange member extending outwardly from the central axis of the sleeve to a point located radially outwardly beyond the exterior surface of the radially adjacent portion of said sleeve,
- said flange member having a continuous, smooth curve perimeter, and being characterized in that, with respect to the axis of the sleeve,
- the radial distance between the exterior surface of the sleeve and the perimeter of the flange continuously increases from each point of least radial distance between the exterior surface of the sleeve and the perimeter of the flange member
- to the point of maximum radial distance between the exterior surface of the sleeve and the perimeter of the flange
- along at least a substantial portion of the two arcs defined between the aforesaid points of least radial distance to the maximum radial distance
- whereby a shearing resistance will be induced in those portions of the flange member corresponding to the aforesaid arcs in response to forces applied to said bushing in a direction tending to cause the bushing to rotate with respect to a receptacle within which it is received.

In a non-rotating sleeve type bushing assembly, the combination of
- a sleeve, said sleeve having
- an exterior surface formed and adapted to be received in a suitable receptacle, such as a bearing housing, and
- an interior surface formed and adapted to receive a rotating member, and
- a flange member,
- said flange member being integral with the sleeve,
- at least one portion of said flange member extending outwardly from the central axis of the sleeve to a point located radially outwardly beyond the exterior surface of the radially adjacent portion of said sleeve,
- said flange member having a continuous, smooth curve perimeter, and being characterized in that, with respect to the axis of the sleeve,
- the radial distance between the exterior surface of the sleeve and the perimeter of the flange continuously increases from each point of least radial distance between the exterior surface of the sleeve and the perimeter of the flange member
- to the point of maximum radial distance between the exterior surface of the sleeve and the perimeter of the flange
- along at least a substantial portion of the two arcs defined between the aforesaid points of least radial distance to the maximum radial distance
- whereby a shearing resistance will be induced in those portions of the flange member corresponding to the aforesaid arcs in response to forces applied to said bushing in a dirction tending to cause the bushing to rotate with respect to a receptacle within which it is received, and
- a bearing housing,
- said bearing housing having a first portion formed and adapted to receive said sleeve portion, and
- a second portion,
- said second portion being contoured substantially complementarily to said flange member,
- the complementarily contour of said second, sleeve receiving portion being so disposed as to snuggly receive and hold said flange member, and thereby said sleeve, in non-rotatable relationship with respect to said bearing housing at at least a plurality of points about the periphery of the flange member.
