Description
The utility model relates to a kind of transmission machinery with electric drive and the comprehensive one of machine driving, is applicable to the industrial technology field.
Existing speed control by alternate magnetic motor is made up of three-phase AC asynchronous motor, electromagnetic slip clutches and tachogenerator, it and the supporting stepless speed regulated AC drive unit that becomes of controller with the degeneration factor that tests the speed, speed ratio is 10:1 to the maximum, and speed adjustable range can be 120-1200r/mlm; The series of products electromagnetic speed regulator that the speed control by alternate magnetic motor derives from, speed ratio is 10:1 to the maximum.
Existing various types of variable-speed motors have any gear ratio of actual needs, and it is the manufacturing machine of stable drive ratio requirement and the intermediate gearing that engine is coupled.
In the reality, when manufacturing machine had both needed certain speed ratio, require to exceed 120-1200y/mlm scope rotating speed in addition again, only single employing speed control by alternate magnetic motor or variable-speed motor are unappeasable.In order to meet the demands, one of drive system design is: speed control by alternate magnetic motor-shaft coupling-variable-speed motor-shaft coupling-manufacturing machine; Perhaps, other engine-shaft coupling-electromagnetic speed regulator-shaft coupling-variable-speed motor-shaft coupling-manufacturing machine.
The purpose of this utility model provides a kind of speed ratio and is 10:1 to the maximum, output speed can be AC stepless accent, varying speed motor and subseries electromagnetism accent thereof, the speed changer of arbitrary value, and it can be reduced to the drive system scheme: alternating electromagnetic is transferred, varying speed motor-manufacturing machine; Perhaps, other engine-shaft coupling-electromagnetism accent, speed changer-manufacturing machine.
The purpose of this utility model realizes by adopting following measure: change the electromagnetic slip clutches output bearing of speed control by alternate magnetic motor into one or more levels gear, this gear can adopt one or more variable-speed bearings, if variable-speed bearing is when centre circle is exported, at centre circle dress shaft coupling.Subseries product electromagnetism for alternating electromagnetic accent, varying speed motor is transferred, speed changer, and its electromagnetic slip clutches axle goes out end bearing and changes one or more levels gear equally into, and this gear can adopt one or more variable-speed bearings equally.
Now in conjunction with the accompanying drawings the utility model is further described:
Fig. 1 is speed control by alternate magnetic electric motor structure figure.
Fig. 2 is the structure chart that the utility model has adopted a variable-speed bearing.
Fig. 3 is the partial structurtes figure that the utility model has adopted two variable-speed bearings.
Fig. 4 is the variable-speed bearing structure chart.
Fig. 5 is the utility model structure chart when being output as the transmission of single-stage speedup.
Fig. 6 is that the subseries electromagnetism is transferred, speed changer structure figure.
With the variable-speed bearing 10 that changes the outfit of the bearing 3 on the accompanying drawing 1 speed control by alternate magnetic motor, see accompanying drawing 2, or several variable-speed bearings, see accompanying drawing 3, axle shown in the accompanying drawing is 1, tachogenerator is 2, magnetic conductor is 4, excitation winding is 5, tooth very 6, support is 7, armature is 8, three-phase AC asynchronous motor is 9.In conjunction with Fig. 4, Fig. 2, when adorning a variable-speed bearing, axle 1 and the inner ring 1 of variable-speed bearing ' be connected, centre circle 2 ' output, gear are the single-stage deceleration transmission; When axle 1 and variable-speed bearing centre circle 2 ' be connected, inner ring 1 ' output, gear are the transmission of single-stage speedup, as accompanying drawing 5.When adorning several variable-speed bearing,, and the inner ring of adjacent two variable-speed bearings is connected by member 15 with centre circle, constitutes multi-stage acceleration or deceleration transmission as Fig. 3.Transfer, when varying speed motor is deceleration transmission, shaft coupling 11 be fixed on the variable-speed bearing centre circle by bolt and nut 12 when alternating electromagnetic, promptly constitute the version of single-stage deceleration or multi-stage speed-reducing transmission.
Alternating electromagnetic accent, varying speed motor are removed three-phase AC asynchronous motor 9, promptly constitute subseries electromagnetism accent, speed changer, as Fig. 6.
As shown in Figure 1, when the magnet exciting coil 5 of speed control by alternate magnetic motor passes through direct current, the tooth utmost point 6 will be responded to the some magnetic poles to alternating polarity of formation, when armature 8 rotates with motor 9, will respond to and produce eddy current, this eddy current and magnetic pole interact and produce torque, and the rotor of rotating band magnetic pole rotates in the same way.The exciting current that changes electromagnetic clutch is the rotating speed of the output torque of scalable electromagnetic clutch, but the mechanical property of itself is very soft.Adopt the controller of tape speed negative feedback (tachogenerator 2), can adjust exciting current automatically and make output speed constant basically according to the signal of tachogenerator.
As shown in Figure 4, the two eccentric bushings of the inner ring 1 of variable-speed bearing ' be, centre circle 2 ' on drive link and rolling element thereof in guide groove, do radial motion, this motion be subjected to outer ring 3 ' constraint, thereby make transport motion, outer ring 3 ' be ring gear.When outer ring 3 ' fixedly, inner ring 1 ' input, centre circle 2 ' the be output as deceleration transmission of sky gearratio; Centre circle 2 ' input, inner ring 1 ' output then are the speedup transmission of empty gearratio.
The utility model can realize that with the output shaft 1 of speed control by alternate magnetic motor and variable-speed bearing inner ring 1 ' or centre circle 2 ' be connected output shaft slows down or the purpose of speedup.When bigger deceleration of needs or speed increasing ratio, can adopt two or more variable-speed bearing, by member adjacent two inner ring and centre circle are connected respectively.Because variable-speed bearing has the version of general rolling bearing, can play bolster, therefore the output bearing 3 of former speed control by alternate magnetic motor can save.
The utility model compared with prior art has above characteristics:
Have the overall characteristic of the fast machine of speed control by alternate magnetic motor and change (subtract or increase), speed ratio is 10:1 to the maximum, and output speed can be arbitrary value, infinite expanding with the scope of application of manufacturing machine direct-coupling transmission; Speed control by alternate magnetic motor and subseries electricity thereof have been kept The advantage of magnetic speed regulator and variable-speed bearing has overcome the very low shortcoming of the former slow-speed of revolution transmission efficiency.
The utility model becomes (subtracting) fast mechanism owing to have machinery, can select during planing machine to drag slow-revving needs by the type of bigger change (subtracting) speed ratio to satisfy manufacturing machine, and allow electromagnetism slip clutch in the work of high rotating speed district, and improved electric property, improved transmission efficiency; The utility model integrates engine, speed regulator, the fast machine of change (subtract or increase), shaft coupling, has simplified transmission system, the characteristics such as have that applied widely, technological performance, control are simple, compact conformation, cost are low, easy to use.
