The beneficial effect of the utility model is: the product of the utility model has significantly reduced the noise that produces in the dough mixing machine working procedure because transmission device all is arranged in the gear-box, alleviates the dough mixing machine user because the uncomfortable feeling that noise causes; Transmission device adopts the tertiary gear transmission, and velocity ratio is high, and output speed is low, safety and reliability; Adopt the helical teeth structure on the high speed shaft of driving mechanism, improved the bearing capacity of gear, prolonged the working life of gear, and made its transmission more stable, noise is littler, and meshing performance is better, has reduced equipment failure rate.The utility model compact structure, cost is low, and applicability is strong.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the utility model is done further detailed explanation.
Fig. 1 is the structural representation of the utility model;
Fig. 2 is the sectional view of the utility model;
Fig. 3 is the decomposing schematic representation of the utility model.
Embodiment
Shown in Fig. 1-3, the dough mixing machine transmission device of a kind of low noise, high transmission comprises gear-box 1, is provided with duplicate gear 2 in the gear-box 1.The lower gear outer gearing of duplicate gear 2 has first driving gear 3, and the outer gearing that cogs has second driving gear, 4, the first driving gears 3 and second driving gear 4 to be positioned at the both sides of duplicate gear 2.First driving gear 3 is a helical gear, is engaged on the left side of duplicate gear 2, and its transmission shaft lower end is fixed on gear-box 1 base, and gear-box 1 top is stretched out in the upper end, and is fixed with synchronous gearwheel 5.The transmission shaft upper end of second driving gear 4 is fixed on gear-box 1 top cover, and gear-box 1 bottom is stretched out in the lower end, and is fixed with the rotating mechanism 6 of kneading dough.Gear-box 1 bottom also is fixed with internal gear 7, and internal gear 7 can not rotate, and is equivalent to be fixed on the annular rack on the gear-box 1.
First driving gear, 3 moduluses are 1, and the number of teeth is 13, and helix angle is 18 °, because this gear rotational speed is higher, load is heavier, and volume is less, so its gear material is a powder metallurgy.
The modulus of duplicate gear 2 lower gears and first driving gear 3 and helix angle pairing, its number of teeth is 58.
Synchronously gearwheel 5 be provided with the synchronous pinion gear 8 that cooperates with it, and connect with synchromesh gear band 9.
