Torque tube and method for mounting and maintaining power transmitting forces

Claim 1

A torque tube and fixed coupling for mounting and coupling a power output member and a power receiving member, this torque tube of tubular configuration and adapted for the mounting of selected power members whose mounting holes fall within the planar extents of the tubular configuration, this tubular coupling including: (a) a tubular member having at least a pair of spaced-apart walls whose outer planar faces are parallel to each other, (b) a pilot hole formed in each of said pair of spaced-apart walls, these pilot holes axially aligned to form a common axis which is normal to the planar face of these spaced-apart walls; (c) a planar surface in each spaced-apart wall sufficient to accommodate mounting holes formed in that spaced-apart wall with one wall having a plurality of holes formed in a pattern and size according to the pattern of holes formed in the power output member and in the opposite wall of a plurality of holes in a pattern and size according to the pattern of holes formed in the power receiving member and after these mounting holes are formed enlarging the pilot holes to freely pass the shafts of the power output member and the power receiving member; (d) an internal space between said spaced-apart walls providing for the extending into said internal space of shaft portions of the power output and receiving members and means for connecting these internally extending shaft portions to provide a power transfer from one shaft to another, and (e) at least one permanently open side of the torque tube which provides always ready access for inserting tightening and adjusting bolts, nuts and couplings in the interior of the torque tube and said tube interior is absent an intended level of lubricant.
