Description
The utility model is able to programme increase that square speed governing differential mechanism relates to be a kind ofly be applicable to that industries such as chemical industry, petrochemical industry, environmental protection, ore dressing, food, weaving are carried out feed separation, concentrated, classification is with the differential mechanism of horizontal helico-centrifuger.And be applicable to the various devices that need accurate speed governing and require two precise synchronization (as the elevator mechanism of consutrode electric furnace etc.).
Horizontal helico-centrifuger is the novel separation machinery that this century, the fifties grew up, and it has applied range, can turn round continuously automatic, for a long time, do not need filter screen, unit throughput is big, and the disintegrate-quality high cost is low, because it has outstanding advantage, is subjected to various countries and generally payes attention to.The horizontal helico-centrifuger principle is the coaxial high speed rotating in the same way of outer drum and spiral internal rotor, after material enters, heavy phase is deposited on the rotatory drum wall, light at internal layer, inside and outside two of horizontal screw machine all is connected on the differential mechanism, and differential mechanism makes inside and outside two to produce a poor rotating speed, makes helical rotor produce end thrust, sediment is pushed to slag exhausting mouth discharge, and gently discharge from flow-off.The domestic and international at present differential mechanism that uses, the poor rotating speed that it can provide determines during fabrication, a kind of poor rotating speed can only be provided, and in fact various material property differences, its centrifugal settling speed difference, require deslagging speed also different, have only the differential mechanism of changing different speed ratios, have the differential mechanism of paying belt pulley to have only to change the belt pulley of paying of different speed ratios to redefine another fixed speed ratio for the differential mechanism of fixed speed ratio.If change the on-stream difference rotating speed of accurately regulating in order to adapt to material concentration, above-mentioned differential mechanism is just powerless.Germany has developed hydraulic type stepless speed regulation differential mechanism abroad at present, and Sweden Alpha Co., Ltd adopts modes such as electromagnetic eddy current braking formula stepless speed regulation differential mechanism.Their shortcoming is a complex structure, difficult in maintenance.Though they have possessed speed-regulating function simultaneously, can't know how many inside and outside two speed discrepancies are, therefore inside and outside two an of cover must be set test the speed or dynamometry square sampling mechanism, not so can't control centrifuge.Because inside and outside two of horizontal screw machine seals, must transform just and can realize the centrifuge body, the square mode that tests the speed both at home and abroad at present has means such as photoelectricity, magnetoelectricity, hydraulic pressure, elastic element, it installs complicated, the information that sampling comes must just can show after treatment, because method is loaded down with trivial details, it is very complicated that horizontal screw machine difference rotating speed is shown, if horizontal screw machine is carried out automatic control, this cover mechanism is just more complicated so.
When the horizontal screw machine sludge buildup too much, when deslagging did not freely block, the frictional force of generation made inside and outside two rotating speeds trend consistent, and this process is called " synchronously ", it is zero that time difference rotating speed takes place synchronously, and the fixed speed ratio differential mechanism because of the fixing structure of speed ratio overload failure part in addition just takes place.And varied regulable speed type differential mechanism, the overload moment that produces in the time of synchronously also will directly put on the inner part in addition of differential mechanism, and the synchronous overload protection mechanism of different principle different structure all must be set.Because horizontal screw machine is individual coaxial, the very low drive line of high-power, interior outer shaft speed discrepancy in the same way, at a high speed,, on-streamly exist great circulating power, its value is tens times of input power, make driving component (that is differential mechanism) bear very big load, make differential mechanism be subjected to very big the influence working life, very fragile.
The purpose of this utility model is the deficiency that exists at above-mentioned horizontal screw centrifuger differential mechanism and system thereof and the square speed governing differential mechanism that increases able to programme that the horizontal helico-centrifuger of a kind of novelty that designs is suitable for, drive mechanism with a kind of novelty makes differential mechanism self not only can produce differential, and energy speed governing, but also has multiple function, but structure is simpler, easily manufactured, cost is low, is applicable to the horizontal helico-centrifuger of domestic and international any specification, any model.
The square speed governing differential mechanism main structure that increases able to programme is made up of speedup system, differential system, speed control system.It is characterized in that the speedup system is made up of a cycloidal-pin wheel train, have the preceding pinwheel of a rotation, cycloid wheel before a pair of and preceding pinwheel is intermeshing, a fixing pre-eccentric axle, front strut bearing pin, and bearing pin simply-support output mechanism comprise front support bracket, intermediate support frame;
Differential system is made up of a cycloidal-pin wheel train, back pinwheel with a rotation, cycloid wheel after a pair of and back pinwheel is intermeshing, can fix also rotatable back eccentric shaft for one, back axis pin of column, and the bearing pin tube props up the formula output mechanism and comprises shared intermediate support frame, rear support bracket, and pays the slipping toothed electromagnetic clutch that links to each other with the back eccentric shaft by the bearing external gear;
Speed control system has two electromagnetic speed regulators of I and II, input belt pulley, measure speed gears, sensor.Two electromagnetic speed regulator tandems are arranged, a shared main motor, the one-level electromagnetic speed regulator links to each other with tie-plate by belt, and the two-stage electromagnetic speed regulator links to each other with the input belt pulley by belt, the one-level electromagnetic speed regulator is used for the outer drum speed governing, and the two-stage electromagnetic speed regulator is used for the helical rotor speed governing.Back eccentric shaft is paid measure speed gears by the bearing external gear and is linked to each other, and differs from rotating speed and shows and automatic control and alarm.Two cycloidal-pin wheel train speed ratios of speedup system and differential system are the same, and what the speed ratio of two trains multiplied each other is long-pending for+1.
The utility model device has following advantage: (one) allows device long-term work under sync state, does not overload.This makes its (1) save the overload protection mechanism that traditional differential mechanism must be placed; because this installs and does not produce overload moment when synchronous; only make that to retrodeviate an axle rotating speed to be zero; if speed control system moment can overcome sediment frictional force; can stop synchronous generation; if this moment is during greater than cycloid train intensity; also malicious event will take place; but at this moment the power source of Po Huaiing is not the horizontal screw machine from sync state; but from electromagnetic speed regulator, and the electromagnetic speed regulator self character has a maximum moment and critical slippage under certain exciting curent, when load surpasses maximum moment; electromagnetic speed regulator output shaft rotating speed begins rapid decline, until last parking.Because electromagnetic speed regulator self has limit square overload protective function, so synchronous overload protection mechanism also need not be set.
(2) can make horizontal screw machine not have carrying out centrifugal settling under the helical blade disturbance, and then input difference rotating speed deslagging, centrifugal settling synchronously once more, deslagging again, make horizontal screw machine energy and scraper centrifugal machine, piston push centrifuge is equally realized interrupted deslagging, can be used for the separation of difficult separation of material, will enlarge the horizontal screw machine using scope.(2) no matter horizontal helico-centrifuger turns round under which kind of rotating speed, from the rotating speed of speed control system input is exactly poor rotating speed, difference rotation speed change and loading moment are varied to direct proportaion, this can accomplish it: (1) makes horizontal screw machine practicable stepless speed regulation in moving the commentaries on classics, and speed adjustable range can be arbitrarily theoretically.
(2) self have poor rotation-speed indication function, just link to each other with the instrument that tests the speed, just can on-stream direct demonstration difference rotating speed.Can remove from the centrifuge body is transformed, and save complicated inside and outside two and test the speed torque measuring mechanism, and computing servo electronics.
(3) electromagnetic speed regulator has permanent torque-output characteristics, and the inside and outside two moment variations immediate responses of horizontal screw machine do not need the moment sampling mechanism during operation to the difference fluctuation of speed, just can carry out the moment sampling.Also differential mechanism itself is exactly main sensor in the automatic control system in other words, thereby simple electric circuit only need be set just can carry out accurate control automatically to horizontal screw machine, will make complicated loaded down with trivial details horizontal screw machine automatic control and alarm become thing simply and easily.(3) electromagnetic speed regulator of speed governing system is dragged by main motor, and speed governing institute wasted work rate is very little, and the adjusting speed accuracy of speed regulator is very high, adds the function of tens times of differential input shaft reductions of speed of the present utility model, makes its adjusting speed accuracy very high.(4) main part in addition of the present utility model all is to be assembled with GB general part, instrument, accessory in addition, and interchangeability is good, and quality is guaranteed, and cost is low, needn't undergo technological transformation just can start.(5) mechanical transmission is the cycloidal-pin wheel train, and volume is little, and transmission efficiency is up to 98%, and transmission is part arrangement mode advanced person in addition, and carry-over moment can be up to one meter to thousands of kilograms one meter of hundreds of kilogram, and intensity is big, long service life.(6) the utility model can carry out stepless speed regulation to outer drum is on-stream, and its maximum speed is limited by horizontal screw machine main bearing limit speed, can arbitrarily change the separation factor of horizontal screw machine, makes horizontal screw machine that very big flexibility and adaptability be arranged.(7) the utlity model has automatic increase moment function, and its structure only increases by three contacts and a variable resistor, can replace the autoelectrinic control gear of an external complexity.
The utility model is described in further detail below with reference to accompanying drawing.
Fig. 1 is the supporting use schematic representation of the utility model and horizontal helico-centrifuger.
Fig. 2 is a horizontal helico-centrifuger with the square speed governing differential design schematic representation that increases able to programme.
With reference to accompanying drawing 1, horizontal helico-centrifuger is with square speed governing differential mechanism (1) and the horizontal helico-centrifuger adapted of increasing able to programme, horizontal helico-centrifuger has outer drum (3), helical rotor (4) is housed in the outer drum, and clear liquid exhaust port (5) is equipped with in outer drum (3) front portion, and taphole (2) is equipped with at the rear portion, main motor (6) is equipped with in horizontal helico-centrifuger outer drum (3) side, first order electromagnetic speed regulator (7), second level electromagnetic speed regulator (8) is by the pulley belt transmission.Form by speedup system, differential system, speed control system with the square speed governing differential mechanism main structure that increases able to programme with reference to accompanying drawing 2 horizontal helico-centrifugers.The speedup system is made up of a cycloidal-pin wheel train, by the preceding pinwheel (11), preceding cycloid wheel (13), the bearing pin simply-support output mechanism front support bracket (10) that are connected with horizontal helico-centrifuger outer drum garden axle, preceding axis pin of column (12), pre-eccentric axle (21), output mechanism intermediate support frame (14) are formed.Preceding pinwheel (11) and horizontal helico-centrifuger outer drum (3) in the speedup system are connected to input shaft.Differential system is by the back pinwheel (15) that links to each other with horizontal helico-centrifuger helical rotor (4), back cycloid wheel (16), and output mechanism rear support bracket (17), back axis pin of column (20), back eccentric shaft (18) constitutes.Back pinwheel (15) and helical rotor (4) in the differential system are connected to output shaft with spline, pre-eccentric axle (21) is a stationary axle, back eccentric shaft (18) and electromagnetic speed regulator are connected to the speed governing axle with belt, it is that speedup system and differential system are shared that the bearing pin tube props up formula output mechanism intermediate support (14), output mechanism is the output shaft of speedup system, also be the input shaft of differential system, two trains are serially connected structures, and speedup system and differential system are contained by the shell that the preceding pinwheel that rotates constitutes.Because the output mechanism of speedup system and differential system is a coaxial configuration, a shared intermediate support (14), its effect is: the transmission of power that the speedup system is come is gone to differential system, and speedup is to be that the speed ratio of two trains is the same with differential simultaneously.So just form current back eccentric shaft and fix, power pinwheel in the past passes to preceding cycloid wheel, passes to the back cycloid wheel by coaxial wheel output mechanism again, and when passing to back pinwheel output then, the speed ratio phase product of two trains is+1.That is the speed ratio of speedup systems communicate be (+a1/b1), the speed ratio that differential system transmits be (+b2/a2), owing to a-1=a2, b1=b2, so (+a1/b=1) * (+b-2/a-2)=+ 1, the a-cycloid wheel number of teeth in the formula, the b-pinwheel number of teeth.Speed control system is arranged a shared main motor (6) by first, second level two electromagnetic speed regulators (7), (8) tandem; one-level electromagnetic speed regulator (7) links to each other with input belt pulley (24) by belt; outer drum (3) is dragged and speed governing; two-stage electromagnetic speed regulator (8) links to each other with input belt pulley (24) by belt, is dragged by main motor helical rotor (4) is carried out constant-torque stepless speed-regulating and the protection of limit square.Back eccentric shaft (18) is paid with measure speed gears (22) by the bearing external gear and is linked to each other, and sensor (23) is contained in measure speed gears (22) side, differs from rotating speed and shows and automatic control and alarm.
The utility model working principle and process:
Drive the I and II electromagnetic speed regulator during main motor rotation, the logical exciting curent of one-level electromagnetic speed regulator drives the outer drum rotation, outer drum drives coaxial preceding pinwheel (11) and drives preceding cycloid wheel (13) again, rotation, because pre-eccentric axle (21) is fixing, and the pinwheel number of teeth is greater than the cycloid wheel number of teeth, so the rotating speed of input is by speedup, and rotating speed is delivered to differential system through output mechanism after this speedup, drives back cycloid wheel (16) and does the constant speed rotation.When back eccentric shaft (18) maintains static when moving because the cycloid wheel number of teeth is less than the pinwheel number of teeth, again because speedup system is that two train speed ratios are the same with differential, so still be lowered by original input speed by the rotating speed of speedup, output to helical rotor by back pinwheel (15), horizontal screw machine is rotated with the sync state input shaft that main motor rotation also drives the two-stage electromagnetic speed regulator (8) of tandem simultaneously that turns round, when the two-stage electromagnetic speed regulator feeds exciting curent, the electromagnetic speed regulator output terminal drives input belt pulley (24) rotation, the big more rotating speed of exciting curent is high more, carries out constant-torque stepless speed-regulating with regulating the exciting curent size.From the rotating speed of back eccentric shaft (18) input and the rotating speed of back cycloid wheel (16), after synthetic in the differential system, the rotating speed of back pinwheel (15) output is changed, break away from sync state and preceding pinwheel (11) and produce a speed discrepancy, thereby two also produce a poor rotating speed inside and outside the horizontal screw machine, thereby reach the purpose of differential function.
