Patent ID: 8479379

Claim:
A blower alignment apparatus, comprising: a base; a housing clamp, articulately mounted to the base, wherein the clamp is configured to releasably engage a roots-type blower to the base, the roots-type blower comprising a blower housing having a driving helical rotor and an idler helical rotor disposed therein, the driving rotor and the idler rotor disposed on a driving shaft and an idler shaft, respectively, and a driving gear and an idler gear disposed on a proximal end of the driving shaft and the idler shaft, respectively; an idler gear control group comprising an idler clamp gear disposed on an eccentric shaft and an idler rotation locking lever configured to rotationally fix the eccentric shaft, wherein the idler clamp gear is configured to mesh with the idler gear; a lever arm comprising a bore configured to engage a distal end of the driving shaft, the level arm further comprising a shaft clamp configured to clamp the distal end of the driving shaft and having a reference surface extending substantially perpendicular to an axis of rotation of the driving shaft deflection gauge, configured to detect and to provide indication of displacement of the lever arm over a range of displacement based on displacement of the reference surface; and a lever arm lock comprising a first and second lever arm deflection screw configured to clamp the lever arm at a position within the range of displacement.
