Abstract
An improved load compensating roller support for a device having upper and lower frames moveable with respect to each other and having conical shaped roller bearings, each of which is rotatably mounted on a stretchable rod whereby when a load exceeding a predetermined amount is placed on one of said bearings, the rod temporarily stretches allowing the bearing to move axially along the converging inclined surfaces of the upper and lower bearing rails so as to allow the bearing to self-adjust and allow the upper and lower bearing rails to move closer together and cause the load to be distributed to adjacent bearings during relative movement of said upper and lower frames with respect to each other.
Claims18
A load compensating roller bearing construction for a device having upper and lower frames movable with respect to each other comprising:
- a. a roller bearing support having a plurality of conical roller bearings therein;
- b. an upper bearing rail attached to said upper frame,
- c. a lower bearing rail attached to said lower frame in juxtaposed relationship with said upper bearing rail,
- d. said upper and lower bearing rails forming at least one pair of converging inclined surfaces being supported by said conical roller bearings in said support, and
- e. means for mounting each of said conical roller bearings in said support for temporary radial movement as well as rotation such that any one of said bearings receiving a load greater than a predetermined amount will temporarily move radially along said converging inclined surfaces of said upper and lower rails so as to allow said bearing receiving said greater load to self-adjust and allow said upper and lower bearing rails to move closer together and cause said load to be distributed to adjacent bearings during relative motion of said upper and lower frames.
A method of constructing a load compensating roller bearing support for a machine having upper and lower frames moveable with respect to each other comprising:
- a. forming a roller bearing support having a plurality of conical roller bearings therein,
- b. attaching an upper bearing rail to said upper frame,
- c. attaching a lower bearing rail to said lower frame in juxtaposed relationship with said upper bearing rail,
- d. forming at least one pair of converging inclined surfaces with said upper and lower bearing rails, said surfaces being supported by said conical roller bearings in said support, and
- e. mounting each of said conical roller bearings in said support for temporary radial movement as well as rotation such that any one of said bearings receiving a load greater than a predetermined amount will temporarily moves radially along said converging inclined surfaces of said upper and lower rails so as to allow said bearing receiving said greater load to self-adjust and allow said upper and lower bearing rails to move closer together and cause said load to be distributed to adjacent bearings during relative motion of said upper and lower frames.
