Background technique
As shown in Figure 1, be existing NZS-9 highly performance concentrator transmission and resilience protective gear operational diagram.Because worm gear and worm screw all have the existence of helix angle, in the course of the work worm screw can be subject to worm gear impose on it axially, effect component to the right so that worm screw produces the trend of play to the right.It is larger that worm gear bears torque load, and worm screw is born the axial force that worm gear applies and strengthens thereupon, and the play trend of worm screw also increases thereupon.The play trend of worm screw is extruding one-level spring directly, one-level spring pressure-ram plectane, push rod plectane extruding two-level spring.When torque load up to a certain degree the time, one-level, two-level spring will be pushed fully, push rod also with play to maximum distance position, this moment, the push rod right-hand member touched the action of linked parking induction part, motor outage, out of service.Like this, just finished once the overload protection to NZS-9 type highly performance concentrator.The effect of Here it is resilience protective gear.But in actual production process, there is problem in the NZS-9 highly performance concentrator, 1, cause frequent parking.Theoretically, parking is just indicating that worm gear has been subject to the effect of overload moment of torsion.Overload should show that the thickening pond Mineral Material is too thick long-pending near the bottom.For the thick long-pending problem of possibility mineral aggregate, traditional way is exactly with high pressure water gun thick long-pending mineral aggregate to be impacted to disperse and suitable dilution.Stopping like this to process takies 12 hours nearly, very large on concentrated operation impact.2, each time linked parking nearly all is accompanied by the fracture of one-level spring.3, the worm screw phenomenon of " altering axle " is always arranged in the operation.Cause large and small gear shaft to cooperating dislocation 30～50mm (the gearwheel width only is 70mm).Gear wear is serious.The existence of these problems causes the repair cycle short, and maintenance cost is high, especially concentrated the carrying out smoothly of producing of impact.
Through the analysis to repeatedly shutting down, found problem, main shaft does not have the sign of distortion; harrow tooth structure is not obviously distortion also; observe the surfaces such as main shaft and rake teeth with magnifying glass, do not find any tiny crackle, this probes into the result and shows: " overload " in past mostly is illusion.Find after opening box body of speed reducer, one-level spring and accessory thereof all by fully squeezed broken, break, the shape of spring itself and associate member thereof is all gone.And two-level spring 4 and associate member thereof are all safe and sound.The true cause of " frequent stop ": at first be I and II spring scarce capacity, spring is easy to compressed, makes that push rod 3 is easy to be extruded, play is to maximum position, touches the induction part that links and causes parking; Next be because the one-level spring by squeeze crack, the offside immediate roof of worm shaft is pressed the push rod disk, causes interlock shutdown.The true cause of " the one-level spring is by squeeze crack ": at first because the ability of spring own is not good; Next be since one-level spring left end immediate roof on the shaft shoulder of worm shaft right-hand member, worm screw shaft shoulder rotation, and one-level spring itself does not rotate, and contacts so that the one-level spring left end one direct sum shaft shoulder is equivalent to the destructiveness of " dry friction " type.The reason that " gearwheel occurs seriously to alter axle with respect to small gear " phenomenon occurs: spring too is extruded, or the one-level spring is by squeeze crack, causes gearwheel with worm shaft play to the right.
