Abstract
The utility model discloses a milling machine power transmission mechanism, which aims to provide a main transmission technical scheme with the advantages of simple structure, short high-speed transmission chain, and reduction of gear noise and power loss. The mechanism comprises a motor, a coupling connected between the motor and a shaft I, wherein the shaft I is a gliding shaft and is provided with a gliding gear; a shaft II is provided with a fixed gear and a gliding gear; a shaft III is concentric with the shaft I and provided with three fixed gears; inner teeth are formed at the upper end of the fixed gear at the upper part of the shaft III; the gliding gear of the shaft I can be meshed with the fixed gear of the shaft II, or meshed with the inner teeth of the gear of the shaft III; a shaft IV is a gliding shaft; upper triple gliding gears are respectively meshed with the three fixed gears of the shaft III; and lower duplex gliding gears are respectively meshed with two fixed gears of a shaft V (a spline housing) and transmitted to a main shaft. As the mechanism adopts a back gear mechanism, only two pairs of gears are required for six-stage high-speed transmission, the transmission chain is short, the power loss is low, and the noise is low.
Description
Technical field
The utility model relates to the milling machine power drive mechanism.
Background technology
The high speed of milling machine gear graduation transmission usually adopts with the low speed reduction of speed gear graduation kind of drive of speedup again.Existing milling machine gear graduation transmission mechanism, the one, its complex structure of transmission chain length, the 2nd, owing to high speed meshing gear logarithm has increased machine noise more or has increased expensive expense in order to reduce noise making gear, the 3rd, because the transmission chain length has reduced transmission efficiency.
The utility model content:
Short, the technical scheme that reduces the main drive gear that wastes loss, reduction grating of gears of driving-chain when technical problem to be solved in the utility model provides a kind of high speed.
The utility model is achieved through the following technical measures.It comprises the shaft coupling that motor, motor are connected with the I axle, and the I axle is slip shaft, shifting slide gear is housed; Split axle has a fixed gear and a shifting slide gear, and the III axle is concentric and three fixed gears are housed with the I axle, and there is internal tooth its fixed teeth upper end, top, I axle shifting slide gear can be respectively with the engagement of split axle fixed gear, also the gears engaged of internal tooth can be arranged with III axle upper end; The IV axle is a slip shaft, and three shifting slide gears mesh with three fixed gears of III axle respectively down, and last double crosslinking sliding gear reaches main shaft with two fixed gears engagements of V axle (spline housing) respectively.
Because the utility model is when high speed, I axle shifting slide gear combines with the inside and outside direct geared of III axle, has only used two pairs of gears to reach main shaft, has shortened drive path, has reduced machine noise.
Description of drawings
Fig. 1 is the schematic diagram of the utility model main transmission structure.
The specific embodiment
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
As can be seen from Figure 1, it is direct-connected with I axle 3 that motor 1 passes through yielding coupling 2, and the shifting slide gear 4 on the I axle can mesh with the fixed gear 5 on the II axle 7, also can mesh with the fixing interior external gear 8 on the III axle 9; 12 times three shifting slide gears 13 of IV axle mesh with III axle 9 fixed gears 11,10,8 respectively; Last duplicate gear 14 can mesh with 16 liang of fixed gears of V axle 15,17 respectively.Shifting slide gear 6 upper ends have dial on the II axle 7, and its dial can slide in shifting slide gear 4 grooves, and shifting slide gear 4 and shifting slide gear 6 are STATEMENT OF FEDERALLY SPONSORED, slippage up and down synchronously in the time of respectively with I axle, the rotation of II axle.
The utility model adopts four pairs of gear reductions of speed in order to obtain lower rotating speed by backgear mechanism.Motor 1 reaches shifting slide gear 4 by yielding coupling 2 and I axle 3, fixed gear 5 engagements on shifting slide gear 4 and the II axle 7, reach shifting slide gear 6 by II axle 7, the external tooth engagement of the fixing interior external gear 8 on shifting slide gear 6 and the III axle 9 reaches fixed gear 8,11,10 on the III axle with power; Stir IV axle three shifting slide gears 13 and double crosslinking sliding gear 14 respectively and can obtain (3x2=) 6 grades of low speed with its respective gears engagement respectively.
The utility model is in order to obtain high rotational speed, and external gear is straight-through in conjunction with (leap backgear) in adopting, and power reaches main shaft and backgear stall by two pairs of gears engaged.Shift fork is stirred II axle shifting slide gear 6 with I shifting slide gear 4 slippage downwards synchronously, makes shifting slide gear 6 and shifting slide gear 4 progressively throw off simultaneously with external tooth, the fixed gear 5 of fixed gear 8 respectively; When shift fork continues to stir the downward slippage of two interlock shifting slide gears 6,4, shifting slide gear 4 promptly with fixing in the internal tooth of external gear 8 mesh, power is directly reached fixed gear 8,11,10 on the III axle 9; Stir IV axle 12 3 shifting slide gears 13 and double crosslinking sliding gear 14 respectively and can obtain (3 * 2=) 6 grades of high speeds with its respective gears engagement respectively.This moment, II axle two gears 5,6 were thrown off stall fully with gear 8,4 respectively.
During 6 grades of high speeds of the utility model, two pairs of gear drives are only arranged, and backgear stall under this state, its driving-chain is short, power wastes little, noise is low.
