Embodiment
Below in conjunction with accompanying drawing the utility model is carried out detailed description:
Extremely shown in Figure 5 like Fig. 3: the mill gear-box, be used to connect drive motor and mill, it comprises that casing 6, casing are provided with cavity volume.Input shaft 5, first output shaft 1, second output shaft 2 and the 3rd output shaft 3 are arranged on the casing 6 through bearing rotationally.Input shaft 5, first output shaft 1, second output shaft 2 and the 3rd output shaft 3 all run through cavity volume.Through the key connection main two gearwheels 51 and two small gears 52 are installed removably on the input shaft 5.Two gearwheels 51 are between two small gears 52.Gearwheel 51 diameters are greater than small gear 52 diameters.Through the key connection two first driven gears 11 are installed removably on first output shaft 1.Through the key connection two second driven gears 21 and secondary driven gear 22 are installed removably on second output shaft 2.Through the key connection two the 3rd driven gears 31 are installed removably on the 3rd output shaft 3.Driving gear 51 and first driven gear 11, second driven gear 21 and the 3rd driven gear 31 distribute according to square or rectangular.The driving gear 51 and second driven gear 21 are positioned on the diagonal of square or rectangular.
Two small gears 52 mesh with two first driven gears 11 respectively.Two gearwheels 51 mesh with two second driven gears 21 respectively.Secondary driven gear 22 and 31 engagements of the 3rd driven gear.
Details are as follows for the working principle of the utility model mill gear-box: drive motor is given input shaft 5 with transmission of power, and input shaft 5 is given second output shaft 2 through the engagement of the gearwheel 51 and second driven gear 21 with transmission of power.Input shaft 5 is given first output shaft 1 through the engagement of the small gear 52 and first driven gear 11 with transmission of power.Through the engagement of secondary driven gear 22 and the 3rd driven gear 31, power is sent to the 3rd output shaft 3.The other end of input shaft 5 stretches out in outside the casing, plays output shaft, transmits rotating speed and moment of torsion.Because input shaft 5 has played the effect of input and output simultaneously; The outputting power of input shaft 5 and three output shaft transmission obtains mean allocation, compares five 17 bearings of original gear case sprocket drive spindle with original design; The utility model only needs eight bearings of four rooted tooth wheel shafts, provides cost savings greatly.Former casing divides three-decker, and existing need be two-layer, makes the utility model mill gear box structure compact like this; Because input shaft 5 is even with the power that output shaft transmits, makes and improved working life by the stressed even of gear and bearing on input shaft 5 and the output shaft.
