The screws (40) have helical flights that intermesh during rotation, and extend between inner and outer ends (44 and 42). The shafts (50) extend between inner and outer ends (68 and 74), and are cantilevered from the base (26) from about the inner end (68) thereof. Each screw (40) is formed with a hollow core (80) for receiving its shaft (50) such that the screw (40) slips onto the respective shaft (50) therefor over the outer end (74) of its shaft (50). The screw pump further includes a keyless locking mechanism (56, 58, 96, or 98) intermediate each shaft (50) and screw (40), which is operative to rotationally lock the shaft (50) and screw (40) together without a key or keyway. | ||||||

| An external gear pump including seals, bearings, bushing/seal housings, choke collars and shafts that are all removable for maintenance and/or replacement without removing either endplate or internals from the case assembly. The preferred pump includes four bearing caps that can be removed without removing the pump from its mounted position. By removing the four bearing caps, access is gained inside the pump housing to all of the seals, bearings, bushing/seal housings, choke collars and most importantly, the drive and idler shafts within the pump housing. Further, the two shafts can be slipped out of the pump without disturbing the internal parts and endplates. This capability facilitates maintenance and replacement of major components without removing the pump from its mounted position. | ||||||
| 80 | Method and apparatus for compressor re-manufacture | US11283800 | 2005-11-22 | US20070116589A1 | 2007-05-24 | Terence Young |
| In a method of repairing a scroll compressor, the casing 100 of the compressor is cut open by making two transverse cuts through the casing to give access to the internal components of the compressor. The casing 100 is then resealed, using two annular reinforcing structures 300, one at each cut, to conserve the dimensions of the casing 100. This allows a scroll compressor to be repaired and re-assembled without losing the fine positioning of internal components which are held in place by the casing 100. Each annular reinforcing structure 300 comprises a ring 310 with an outwardly directed flange 305. The flange 305 has a thickness chosen to conserve the dimensions of the re-assembled casing while allowing single-pass welding and the ring 310 has a length which is chosen to provide at least location of the cut surfaces of the casing 100 during re-assembly and, optionally, shielding to prevent weld pool, slag or splatter entering the canister 100. | ||||||
