METHOD OF ASSEMBLING GEAR PUMP Russian patent published in 1995 - IPC

FIELD: mechanical engineering. SUBSTANCE: at first, driving and driven gears are received in the cylindrical bores made in the housing. The driving gear is set in the sliding bearings mounted in the covers through journals. The driven gear is mounted on the axle through a bearing bushing. The ends of the axle is set in bores made in the covers. For final assembling, the pump with loosened bolts is secured at the centers of an attachment for assembling through the driving gear. The covers bears on the spring-loaded members from the side of the driven gear. The spring- loaded members are secured to the fixed side of the attachment. Next, by applying an effort to the housing from the side of the inlet space, the housing is brought into engagement with toothings of both gear and the bolts is tightened finally. EFFECT: simplified assembling. 4 dwg
