Abstract
The utility model relates to an ultralong coupling which is mainly used for cooling fans on large water cooling towers. The utility model is characterized in that a driving device and a driven device are connected together by two half couplings; the middle part is provided with a barrel the inner part of which is provided with a connecting pull rod. The utility model has the advantages of simple structure light weight, convenient installation and long service life.
Description
The utility model relates to a kind of coupling, belongs to machinery.
At present, on the large-scale cooling tower at home, cooling blower is installed in cooling tower inside, and motor is installed in the outside of cooling tower, between the two apart from bigger.Its Placement is to increase a driving support seat in the middle of blower fan and motor, with this driving support seat is mid point, with two axles motor is connected with blower fan respectively, the subject matter that this mounting type exists is that comparatively complexity is installed, centering is difficulty relatively, and in the process of operation, driving support seat is worn and torn easily, the situation that causes centering constantly to worsen finally causes machine breakdown.
The purpose of this utility model is to provide a kind of coupling of overlength.
The technical solution of the utility model is: it is made up of cylindrical shell, pull bar, block, half-coupling, is provided with baffle plate on the inwall of the two ends of cylindrical shell; Center at cylindrical shell is provided with pull bar; Two of pull bar is connected on the baffle plate by nut; The fixedly connected block in the two ends of cylindrical shell, half-coupling are arranged on the block shaft at two ends of cylindrical shell.
By this design, the driving support seat in the middle of having removed makes the installation of coupling become very simple, centering is also very simple, since removed middle driving support seat, the situation that in running, can not cause centering to worsen because of the driving support seat wearing and tearing, and therefore operation is comparatively reliable.
Fig. 1 is a structural representation of the present utility model
Fig. 2 is the pull bar schematic representation
Fig. 3 is the block schematic representation
Fig. 4 is the half-coupling schematic representation.
Describe embodiment of the present utility model in detail below in conjunction with accompanying drawing:
The utility model is made up of cylindrical shell 4, pull bar 3, baffle plate 5, nut 6, block 2, half-coupling 1, and cylindrical shell is a metal cylinder, welding baffle plate 5 on the inwall at cylindrical shell two ends, and two of pull bar 3 is connected in the center hole of baffle plate 5 by nut 6.The pretightening force of nut is for tight more good more.One of block is stretched into cylindrical shell end and cylindrical shell welding, and the other end of block is the axle of band keyway, and half-coupling is arranged on the axle of block, is the interference fit key connecting between half-coupling and the block.Will note following item when mounted: at first metal cylinder all will carry out dynamic balance running and coaxality inspection after the completion of processing, then, pull bar is welded in the cylindrical shell, will carry out the radial beat eccentricity inspection to cylindrical shell after welding finishes, block is installed then, the cooperation of block and inner barrel is a drive fit, after installing, to carry out the coaxality inspection, then block is welded on the cylindrical shell, after welding finishes, whole parts is carried out the coaxality inspection.At last half-coupling is installed on the block, links to each other with blower fan with motor respectively then.
