Bearing play adjusting assembly
A bearing play adjusting assembly is useable to adjust the bearing play in an axle journal of a printing plate cylinder of a rotary printing press. A pressure plate is secured to an end of the axle journal and bears against an inner bushing. A shim plate is placed between the pressure plate and the axle journal end. The thickness of the shim plate can be changed to adjust the bearing play of the cylinder axle journal bearing.
What is claimed is:
1. A bearing play adjusting assembly which is useable to effect adjustment of bearing play in a cylinder of a printing press, said bearing play adjusting assembly comprising:
an axle journal extending from a plate cylinder and being rotatably supported in a printing press;
a bearing having a conical inner race rotatably supporting said axle journal;
an inner bushing carried by said axle journal and having a first end which is engageable with said bearing;
a pressure plate securable to an end of said axle journal and engageable with said inner bushing;
a shim removably positioned between said pressure plate and said end of said axle journal;
an outer bushing concentrically supported on, and axially shiftable with respect to said inner bushing; and
means to adjust circumferential play between said inner and outer bushings.
2. The bearing play adjusting assembly of claim 1 wherein said shim is made of metal.
3. The bearing play adjusting assembly of claim I wherein said shim is made of plastic.
4. The bearing play adjusting assembly of claim 1 wherein said means to adjust circumferential play includes a frustoconical recess in an end of said axle journal and a frustoconical body receivable in said recess and slidable thereon to vary a diameter of said axle journal and said inner bushing.
