Patent ID: 11852123

Abstract:
An oil bath geartrain for a powermill includes a gear casing defining an interior area having an oil reservoir that maintains a predetermined oil level and which includes structures for continuously distributing oil to gear teeth and babbitt bearings so that recurrent servicing of gear-related components is not necessary. The oil bath geartrain includes an oil lift gear having teeth that lift oil from the oil reservoir and then lubricates and input shaft bearing and communicates that oil via an oil ring so as to lubricate an intermediate shaft bearing. The oil ring acts as an oil scraper. The oil bath geartrain includes a main pinion gear, intermediate pinion gear, and accommodation of miter gears coupled to the output shaft. Another oil scraper plate communicates oil from the main pinion gear to the output shaft miter gear teeth. The gear casing includes passages for communicating oil to input shaft bearings.
