Description
Technical field
The utility model relates to a kind of link, specifically, relates to a kind of lengthened coupling device connecting motor and the pump housing.
Background technique
In prior art, horizontal centrifugal pump comprises support and the motor that is fixed on support and the pump housing, to be linked into an integrated entity transmission between the motor shaft of motor and the pump shaft of the pump housing by coupling.
Chemical centrifugal pump coupling system sold in the market, even if also without any revolution gap when bearing load, even if when having deviation to produce load, coupling or rigid of transmission moment of torsion, especially in running up, producing high temperature makes the relative displacement of between centers increase and make bearing load strengthen the deviation causing in system, thus may cause axle, bearing or the too early damage of coupling.
Summary of the invention
The object of the invention is to overcome above-mentioned deficiency, thus provide a kind of structure simple, connect and reliably, easily fill readily removable, have the lengthened coupling device of certain damping and damping capaicty, thus conveniently can carry out the dismounting maintenance work of pump, bring convenience to maintenance man, improve working efficiency.
A kind of lengthened coupling device, comprise pump coupling, intermediate shaft coupling, motor coupler, also include lengthened coupling, two end flange face of described lengthened coupling are provided with annulus boss, described intermediate shaft coupling and the end face of flange of motor coupler are respectively arranged with the groove coordinated with annulus boss, described lengthened coupling one end is connected with motor coupler flanged surface by bolt, the described lengthened coupling the other end is connected with pump coupling flange face through intermediate shaft coupling by bolt, elastic buffer block is provided with between described intermediate shaft coupling and pump coupling.
Further, described elastic buffer block is the equally distributed block rubber of six teeth.
As optimization, the thickness of described elastic buffer block is 25-35mm.
The utility model structure is simple, compact, reasonable, have employed lengthened coupling, applied widely, and during maintenance, motor does not need displacement, and easy accessibility, improves working efficiency; Meanwhile, allowable rotating speed is high, and can transmitting large torque, axially, radial displacement, has certain damping and damping capaicty.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is elastic buffer block structure schematic diagram of the present utility model;
Fig. 3 is the A-A sectional view of Fig. 2.
1 pump coupling, 2 intermediate shaft couplings, 3 lengthened couplings, 4 motor couplers in figure, 5 elastic buffer blocks, 6 bolts, 7 annulus boss.
