Abstract
The invention is an improvement in a gear assembly having a gear segment attached to a spider. The improvement comprises a pair of spaced spider webs and a segment-attached mounting member received between the webs. The mounting member has a pair of spaced plates, one plate against each web. Each of a group of tube-like generally cylindrical segment coupling members extends between a particular web and its adjacent plate while each of another group of coupling members extends between the other web and its adjacent plate. The coupling members of a group are in opposed relationship to corresponding coupling members of another group. A bolt-like retaining member extends through each pair of opposed coupling members (with clearance therebetween) and prevents such members "working" out of position.
Claims7
In a machine assembly having a gear segment attached to a spider, the improvement comprising:
- a pair of spaced spider webs;
- a segment-attached mounting member received between the webs, the mounting member including spaced plates;
- a segment coupling member extending between a web, the mounting member and a plate;
- and,
- a retaining member extending through a web and the coupling member with at least slight clearance.
In a machine assembly having (a) an axis of rotation nd (b) a gear segment attached to a spider, the improvement comprising:
- a pair of spaced spider webs;
- a segment-attached mounting member received between the webs;
- a segment coupling member having a generally cylindrical interior surface, the coupling member extending between a web and the mounting member;
- a bolt which is (a) generally parallel to the axis of rotation, and (b) spaced from the interior surface, the bolt extending through a web and the coupling member with at least slight clearance;
- and
- a collar interposed between the bolt and the coupling member and supporting the bolt generally concentric to the coupling member.
