Abstract

PURPOSE:To simplify the structure while to facilitate assembling and maintenance by holding the bearing section at the side face of gear of motor fittably to the gear box then gearing the gear at the end of motor shaft with the gear of gear shaft at the impeller side thereby shortening the axial length considerably. CONSTITUTION:An impeller 2 is over hanged from a pinion shaft 4 having a pinion 3 while the motor shaft 12 is supported by bearings 18, 19 in end brackets 16, 17 where a gear 8 is over hanged from one end of motor shaft 12. The bearing section 21 for supporting the bearing 18 at the gear 8 side is projected and held fittably in the gear casing 5 to gear the gear 8 at the end of motor shaft with a pionion 3 of pinion shaft. Consequently, the axial length is shortened considerably to reduce the installation area. Consequently, parts such as coupling, gear bearing can be eliminated resulting in simplification of structure and facilitation of assembling, maintenance.
