Abstract
The renovated bearing and the method of constructing the renovated bearing includes a trimmed off foundation base with a new wear block secured to the foundation base and adapted to bear against a rotating shaft to keep it from vibrating or otherwise rotating out of true. By reusing, or rather continuing using, a foundation base portion of an existing bearing, only the duty wearing block component can be replaced simply and economically. This reduces wastage of the larger bearing composition mass. A like-new bearing can be assembled quickly and more economically than a complete replacement of a bearing.
Claims12
A renovated shaft bearing comprising:
- a foundation base and a replacement wear block;
- wherein the foundation base is adapted to fit securely in a bearing housing, and the foundation base includes a contact side that is adapted to be oriented to face a rotating shaft;
- wherein the replacement wear block has a back side and on its opposite side to the back side a wear face, and the back side is fixed to the contact side of the foundation base and the wear face is shaped to engage an outside diameter of the rotating shaft.
A method of making a renovated shaft bearing comprising the steps of:
- removing a shaft bearing from a bearing housing;
- wherein the shaft bearing has a contact face that engages a rotating shaft;
- cutting off the face of the shaft bearing to form a foundation base of the remaining portion of the shaft bearing, and the foundation base includes a contact side that is adapted to be facing the rotating shaft;
- providing a replacement wear block that has a back side and a wear side, and wherein the back side of the replacement wear block has a surface that is adapted to be secured to the contact side of the foundation base;
- securing the back side of the replacement wear block to the contact side of the foundation base;
- and
- milling a radius of the rotating shaft into the wear side of the replacement wear block,
- whereby the combination of the wear block face and the foundation base form a new shaft bearing.
