Description
Technical Field
The utility model relates to a shaft coupling for vertical pipeline pump belongs to mechanical transmission technical field.
Background
The vertical pipeline pump is a centrifugal pump capable of conveying clear liquid or conveying turbid liquid containing a small amount of solid particles, and is widely applied to industries such as petrochemical industry, papermaking, thermal power generation, seawater desalination, industrial water circulation, cooling tower water supply, diesel oil conveying, regional centralized heat supply, regional centralized cooling and the like. The shaft coupling is the main driving medium of vertical tubing pump, and the shaft coupling of traditional vertical tubing pump includes that two overlap respectively at the half-couplings of driving shaft link and driven end axle link, and every half-coupling is the cylinder adapter sleeve, and every half-coupling inner wall passes through the parallel key with the transmission shaft that links respectively and is connected, and the butt joint end of two half-couplings is equipped with flange, and the flange of two half-couplings passes through the screw nut to be fixed, realizes the transmission of driving shaft and driven shaft. In the long-term rotation process of the driving shaft and the driven shaft, radial vibration can inevitably occur, so that shearing force is formed on the screws of the two connecting flanges of the fixed coupling, the screws and the nuts are loosened, and the radial vibration effect is aggravated. In order to solve the problem, a rubber elastic sleeve is arranged between each connecting screw and the screw hole of the connecting flange so as to eliminate the radial vibration effect; however, the rubber elastic sleeve is easy to damage and needs to be replaced frequently.
SUMMERY OF THE UTILITY MODEL
The utility model aims at providing a shaft coupling for vertical tubing pump in order to solve the shaft coupling structure of traditional vertical tubing pump and have rubber elastic sleeve fragile, the inconvenient scheduling problem of dismouting of pump, and provide a shaft coupling for vertical tubing pump.
The utility model aims at realizing through the following technical scheme:
the utility model discloses a shaft coupling for vertical pipeline pump, overlap the half-coupling at driving shaft link and driven shaft link including two respectively, every half-coupling is the cylinder adapter sleeve, and every half-coupling inner wall passes through the parallel key with the transmission shaft that connects respectively, and the butt joint end of two half-couplings is equipped with flange, and two half-coupling's flange passes through screw nut fixed, and is equipped with the elastic sleeve between every connecting screw and flange's the screw hole, the elastic sleeve supports the cover including two cylinders of inside and outside setting to and cement at two cylinder metals and support the elastic interlayer between the cover.
The two cylindrical supporting sleeves of the elastic sleeve are made of metal materials.
The elastic interlayer of the elastic sleeve is made of rubber materials.
Elastic interlayer flushes with the axial both ends of outer layer support cover in the elastic sleeve, and elastic interlayer is good at inner layer support cover axial both ends, and the shearing effect of screw to elastic interlayer tip when avoiding radial tremble.
Has the advantages that:
the utility model discloses a shaft coupling for pump, simple structure, easy dismounting, the special design of packing rubber in the middle of the elastic sleeve adopts inside and outside metal ring, has avoided the rubber spare direct and connecting piece contacts such as screw, flange, and the protection rubber spare that can be better has prolonged the shaft coupling life-span, makes the atress of rubber spare more even simultaneously, absorption vibration that can be better, compensation installation deviation.
