Abstract: Improved serviceability of cold metal cutting machines is accomplished in a modified gearbox structure enabling several annular components that are conventionally attached by press-fit to be attached instead by slide-fit for easy removal and replacement, eliminating hammering and/or heating required conventionally to release press-fit components. Press-fitting of a motor shaft coupling is eliminated by introduction of clamping slide-fit structure. Press-fits of two thrust bearings to the housing are eliminated by introduction of slide-fit adaptors. Instead of the conventional practice of making the saw rotor integral with the low speed shaft, a separate saw rotor bolted to the shaft enables easy replacement of the oil seal.

Abstract: The bearing assembly includes a synthetic resinous collar which circumscribes the tube and oscillates therewith against the inside of a metal bushing wedged within a metal housing that is bolted to the adjacent tine tube carrier arm of the reel. The bushing is constructed from a pair of generally semicircular half-sections that are abutted together to make a complete annulus when held within the housing, thereby permitting removal of the bushing from the tube by simply separating the two half-sections from one another after the housing has been slipped axially off the end of the bushing. A slit in one side of the collar permits opposed wall portions thereof to be spread apart so that the collar may likewise be removed from the tube in a transverse direction rather than requiring axial movement along the tube which would be obstructed by crop-engaging tines of the reel.
