Abstract
In an augering apparatus for rotating and advancing a cutting head longitudinally of the apparatus driven by a string of auger flights with helical flighting, an auger flight support comprising a plurality of radially extending support legs affixed to a bearing housing surrounding a bearing rotatably affixed to the auger drive shank disposed at one end of a two-ended auger flight to support the auger flight independently of the support provided by the auger flighting to reduce wear and tear of the helical flighting and to eliminate frictional drag of the string of auger flights.
Claims4
In an augering apparatus for rotating and advancing a cutting head driven longitudinally of the auger by a string of two-ended auger flights having helical flighting, the improvement of an auger flight support adapted to support at one end auger flight with helical flighting and comprises:
- A bearing rotatably affixed to an auger drive shank at one end of an auger flight with two ends;
- A bearing housing surrounding the bearing and adapted to accept a plurality of support legs extending radially from the bearing housing and the drive shank of the auger flight;
- A plurality of support legs extending radially from the bearing housing to a predetermined length;
- A bearing seal disposed between the bearing housing and bearing.
