In the accompanying drawings: 1, pull bar; 2, clamp nut; 3, base plate; 4, jack; 5, pipe nipple; 6, jackscrew; 7, hollow shaft; 8, top board; 9, coupler; 10, coupler take-off (propeller) shaft.
The specific embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
Fluid coupling be take a kind of nonrigid coupling device that liquid is working media, claim again fluid coupling, the pump impeller of fluid coupling and turbine form an airtight working chamber that can make liquid-circulating flow, pump impeller is contained on power shaft, turbine cartridge is on output shaft, engine (internal combustion engine, when motor etc.) band driven input shaft rotates, liquid is centrifuged formula pump impeller and throws away, this high-speed liquid promotes turbine rotation after entering turbine, the energy obtaining from pump impeller is passed to output shaft, final liquid returns to pump impeller, what formation went round and began again flows, fluid coupling is by liquid and pump impeller, the variation that the blade interaction of turbine produces the moment of momentum carrys out transmitting torque, its output torque equals input torque and deducts moment of friction, so its output torque perseverance is less than input torque, between fluid coupling power shaft and output shaft, lean on liquid communication, between working component, there is not rigid attachment, the feature of fluid coupling is: can eliminate shock and vibration, output speed is lower than input speed, the speed discrepancy of diaxon increases with the increase of load, overload protection performance and starting performance are good, during excessive the and stall of load, power shaft is still rotatable, the unlikely damage that causes engine, when load reduces, output shaft rotating speed increases until close to the rotating speed of power shaft, in concrete application process, for reducing fluid coupling total quality, its shell all adopts aluminum alloy material casting to form, it is careful with anti-tamper main frame accessory during dismounting, to need, simultaneously because material property determines, frock cannot be installed on fluid coupling surface when dismounting fluid coupling, to maintenance, make troubles, reduce maintenance efficiency, for this reason, the utility model provides a kind of fluid coupling nondestructive demounting frock as shown in Figure 1, it comprises base plate 3, top board 8, pull bar 1, jack 4, hollow shaft 7 and jackscrew 6, described base plate 3 is connected by means of pull bar 1 with top board 8, pull bar 1 arranges two, two pull bar 1 two ends are respectively through the through hole setting on top board 8 and base plate 3, two pull bar 1 two ends are the supporting clamp nut 2 that arranges respectively, described base plate 3 and top board 8 be arranged in parallel, the radical of pull bar can be adjusted into more, minimum two, two pull bars and top board and base plate can form cage structure, its supporting role, described hollow shaft 7 is through the through hole setting at described top board 8 middle parts, described jackscrew 6 is through the through hole setting at hollow shaft 7 middle parts, described jack 4 bottoms are fixed on base plate 3 side relative to top board 8, and its axis and jackscrew 6 deads in line, the axis of described two pull bars 1 and jackscrew 6 axis are positioned at same plane, described hollow shaft 7 is multidiameter, its diameter equates with top board 8 middle through-hole internal diameters compared with the external diameter of segment, larger section of its diameter is positioned between top board 8 and base plate 3, described hollow shaft 7 diameters are provided with the external screw thread with fluid coupling end screw-internal thread fit compared with the end of segment, hollow shaft can be secondary multidiameter, also can be three grades of multidiameters, its large end is positioned at top board inner side, and its diameter is greater than the diameter of top board middle through-hole, rise and support and guide effect, described base plate 3 is circular ring, its middle part is provided with the through hole with jack 4 bottom tablings, and its lateral surface is provided with the shrouding for support jack 4.
In concrete application process (referring to Fig. 2), first by top board 8 and hollow shaft 7 assemblings, hollow shaft small end passes outwards through top board middle through-hole, the two matched in clearance, then hollow shaft 7 is connected fastening with fluid coupling outer casing end internal thread, secondly jackscrew 6 is inserted in hollow shaft 7, and according to Fig. 1 order mounting base and pull bar fastening with clamp nut, finally jack is inserted in top board mider hole, by jack piston rod over against jackscrew end face, adjust jack, make piston rod compress jackscrew painstaking, then adjust frock and align jackscrew, continue to adjust jack, make gradually fluid coupling output shaft separated with reductor power shaft, reach the object of dismounting fluid coupling, in use can also be along with jack-in process increases pipe nipple according to jack jacking stroke between jack piston end and jackscrew, guarantee jack stability in use.
In a word, the utility model by setting take over a business, chassis and pull bar be as the fixing parts of jack, corresponding jack is placed between two dishes, jack to stretch out piston rod relative with jackscrew, the nut check of pull bar both sides.Jack piston rod is stretched out and gradually power passed to jackscrew and coupler take-off (propeller) shaft, and along with jack piston rod extends, power transmission shaft just can be separated with fluid coupling, reaches the object of convenient and swift dismounting fluid coupling.
