US 10,801,550 B1 · Encoder system and method of assembly for large bearings

Abstract

An encoder system mounted on a large diameter bearing, the large diameter bearing having an inner ring and an outer ring, the encoder system providing a tensioning assembly mounted in a pre-machined portion of the inner ring, the tensioning assembly including a first tensioning part having a first machined recess and a first groove, and a second tensioning part having a second groove, the second tensioning part conforming in size and shape to the first recess and disposed within the first machined recess. The tensioning assembly is centered and fixed on to the inner ring. An encoder assembly mounted on the outer ring, the encoder assembly including a first encoder part fixed to the outer ring, and a second encoder part fixed to the first encoder part and aligned in front of the encoder band. A method of assembling an encoder system to a large diameter bearing is also provided.

A method for assembling an encoder system to a bearing, the bearing having an inner ring and an outer ring, the method comprising the steps of:

providing a tensioning assembly including;
a first tensioning part having a first machined recess, and
a second tensioning part, the second tensioning part conforming in size and shape to the first machined recess and having a cleat,
inserting the second tensioning part into the first machined recess and securing it into place,
inserting the tensioning assembly in a pre-machined portion of the inner ring and securing it in place,
machining simultaneously a first groove in an outer diameter of the first tensioning part, a second groove in an outer diameter of the second tensioning part, and a third groove in an outer diameter of the inner ring, and wherein
the simultaneous machining of the first groove, the second groove, and third groove in their respective outer diameters assures the second groove of the second tensioning part is centered with respect to the third groove on the inner ring.
