Description
Technical field
The utility model relates to milling machine variable-speed dynamic head.
Background technology
Present milling machine power speed changing transmission has following several mode: the one, and belt transmission; The 2nd, gear drive; The 3rd, frequency conversion (or servo) motor-driven; The 4th, the frequency conversion belt transmission.Though belt transmission should run up, easily skid when be difficult to realizing, moment of torsion is little, the speed change trouble than the slow-speed of revolution and low speed; Noise height, complex structure during the big but high speed of gear drive low speed torque; Frequency control drive mechanism simple variable-speed is convenient, but low speed torque is little; Also have patent (variable-frequency control dynamic head) to adopt frequency control through the two-stage belt deceleration, the low speed power output is still little, and high speed is limited.
The utility model content:
For overcoming the prior art defective, moment of torsion was big when technical problem to be solved in the utility model provided a kind of low speed, slewing range is wide and suitable high-speed cutting and noise is little, power loss is few, the technical scheme of infinite variable speed main drive gear.
The utility model is achieved through the following technical measures.Motor is by Frequency Converter Control, and motor shaft is provided with driving pulley, and connects driven pulley by belt, driven pulley is provided with on the I axle, the I axle is provided with shifting slide gear, shifting slide gear can with II axle (both parallel axes) fixed gear engagement, also can with the internal tooth engagement of fixed gear on the III axle (both concentric shafts); II axle lower end is provided with shifting slide gear, can mesh with the fixed gear external tooth on the III axle, and the III axle is connected with main shaft.
Because the utility model can pass through the further reduction of speed of one-level belt, two-stage gear and motor frequency modulation, can obtain the low speed segment infinitely variable speeds; Also can be by shifting slide gear and coaxial internal tooth engagement, power is only used the one-level belt transmission, and with motor frequency modulation speed change, can obtain the high regime infinitely variable speeds.
Description of drawings
Fig. 1 is the schematic diagram of the utility model main transmission structure.
The specific embodiment
The utility model is achieved through the following technical measures.Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
Among Fig. 1, motor 1 is by Frequency Converter Control, and motor shaft is provided with driving pulley 2, and by belt 3 connection driven pulleys 4, driven pulley 4 is provided with on the I axle 5, and the I axle is provided with shifting slide gear 6, shifting slide gear 6 can with the engagement of II axle 8 fixed gears 7, also can with the internal tooth engagement of fixed gear 10 on the III axle 11; II axle 8 lower ends are provided with shifting slide gear 9, can mesh with fixed gear 10 external tooths on the III axle 11, and the III axle is connected with main shaft.
The utility model can be operated in the following manner: low speed segment: power reaches driving pulley 2 by motor, reach I axle 5 by belt 3 driven pulleys 4, shifting slide gear 6 and 7 engagements of II axle fixed gear, power reaches the III axle to main shaft by the external tooth engagement of the shifting slide gear on the II axle 9 with fixed gear 10.Its power can obtain the low speed segment infinitely variable speeds through the three grades of reductions of speed and the further reduction of speed of motor frequency modulation of two pairs of gears of one-level belt; High regime: shift fork is stirred I axle shifting slide gear 6 and is moved down, and makes shifting slide gear and II axle fixed gear 7 throw off, also progressively mesh with fixed gear 10 internal tooths, and its power external tooth in the one-level belt is straight-through and cooperate motor frequency modulation, can obtain the speed change of high regime.When shifting slide gear 6 and II axle fixed gear 7 were thrown off, the shifting slide gear 9 that shift fork is stirred on the II axle was simultaneously thrown off simultaneously with the external tooth of fixed gear 10, and this moment, II axle two gears 7,9 were thrown off and stall fully with gear 6,10 respectively.The utility model is in order to obtain high rotational speed, and external gear is straight-through in conjunction with (leap backgear) in the employing, and power is directly reached main shaft, also passes through motor frequency modulation, obtains the high regime infinitely variable speeds.
The utility model is when high speed, interior external gear is straight-through, and power is only used the one-level belt transmission in conjunction with (backgear stall), and with motor frequency modulation speed change, shortened two-stage gear reduction of speed driving-chain, can obtain high rotational speed, its driving-chain is short, power loss is little, noise is little; And adopt one-level belt and the two-stage gear rotating speed of being degraded three ranks at low speed segment, and also can adopt the further reduction of speed of motor variable-frequency speed-regulating, can under lower rotating speed, obtain bigger moment of torsion, transfer motion power is big, and running is steady.
Because the utility model reasonably combines independent belt transmission, independent variable-frequency motor transmission or independent gear drive, can select low speed segment to adopt the mode of belt, gear combination reduction of speed to obtain the slow-speed of revolution, high pulling torque at the difference of concrete processing mode; Select high regime directly to reach main shaft, so that carry out high-speed cutting through the one-level belt.
The utility model adopts the optimum organization of motor variable-frequency speed-regulating, belt transmission, three kinds of speed change kinds of drive of gear reduction of speed when low speed, the drawback of making the best use of the advantages, mutual supplement with each other's advantages, and its running is steady, low speed torque is big; Shorten driving-chain during high speed, reduced power loss, reduced grating of gears.It is little to have solved current general unit head low speed torque, and the technical problem that slewing range is narrow, high speed is limited and noise is big because the utility model has adopted frequency control, can realize infinitely variable speeds, and is easy to use.
