MOUNTING STRUCTURE FOR MOUNTING GAUGE WHEEL ASSEMBLY TO IMPLEMENT
First Claim
1. A row unit for an implement, comprising:
- a frame;
a gauge wheel assembly;
a pivot arm having a first end coupled to the gauge wheel assembly and a second end comprising a hub for pivotally mounting the pivot arm to the frame, said hub having a bore therethrough;
a cylindrical member having an inner end and an outer end, said cylindrical member extending through the bore of said hub with the inner end of the cylindrical member adjacent to the frame and the cylindrical member being coaxial with the bore of the hub;
an adjusting sleeve having an outer end, an inner end, an inner bore, and a threaded outer surface, said adjusting sleeve being positioned coaxial with said cylindrical member with the inner end of the adjusting sleeve adjacent to the outer end of the cylindrical member;
a mounting bolt having a head at one end, the bolt extending through the inner bore in the adjusting sleeve with the bolt head adjacent to the outer end of the adjusting sleeve and a threaded portion of the bolt extending beyond the inner end of the adjusting sleeve for insertion into a female threaded portion of said cylindrical member or the frame, said mounting bolt being threaded into the female threaded portion and tightened to fix the cylindrical member and adjusting sleeve to the frame while allowing rotation of the hub and pivot arm about the cylindrical member;
at least one disc spring positioned on said adjusting sleeve; and
a nut threaded onto said threaded outer surface of said adjusting sleeve, said nut compressing said disc spring to restrain said hub on said cylindrical member such that compression of said disc spring creates a lateral bearing force on said hub which is transferred to said frame.

Abstract
A mounting structure for mounting a pivot arm to an implement has a cylindrical member, an adjusting sleeve, and a mounting bolt extending through the cylindrical member and adjusting sleeve to fix the cylindrical member and adjusting sleeve together. The cylindrical member extends through a bore of a bearing housing for rotation within the bearing housing. The adjusting sleeve has a threaded external surface. A disc spring is positioned on the adjusting sleeve. An adjusting nut is threaded onto the threaded external surface of the adjusting sleeve. The adjusting nut can be tightened to compress the disc spring to create a lateral bearing force against the bearing housing. The bearing housing can be integral with a pivot arm for mounting a gauge wheel assembly on a planter row unit, or the bearing housing can be a fixed part for mounting a pivot arm for a closing/press wheel on a drill.
