MINIMIZING BEARING FAILURE DUE TO STALK ROLL MISALIGNMENT

摘要

A corn header has a plurality of row units disposed adjacent each other. Each row unit has a frame and a gearbox coupled to the frame. The gearbox has a gearing assembly coupled to a rotatable shaft extending from an opening of the gearbox. Each row unit also has a stalk roll coupled to the rotatable shaft and a coupling interface comprising a self-aligning ball or roller bearing assembly. A support bracket is secured to the frame with the coupling interface operably coupling the stalk roll to the support bracket within a defined tolerable limit of misalignment.

主权项

1. A row unit for a corn header comprising:
a frame; a gearbox coupled to the frame, the gearbox having a gearing assembly coupled to a rotatable shaft extending from an opening of the gearbox; a stalk roll having first and second ends, the first end coupled directly to the rotatable shaft, the second end coupled via a coupling interface to a support bracket, the support bracket coupled to the frame; and a self-aligning ball bearing assembly located at the coupling interface, the self-aligning ball bearing assembly compensating for misalignment between the first end and the second end.
