Abstract
The utility model provides a blender power transmission gear case. The gear case is characterized in that the gear case adopts a circular sealed combination structure, large reduction ratio is formed through a pair of screw umbrella gear pairs with large coprime numbers teeth number, each screw umbrella gear pair is of a structure with two ends supported, and eventually the screw umbrella gear pairs are connected with an output shaft of a spline and a spline housing so as to output torsion. The blender power transmission gear case has the advantages of being stable in transmission, capable of avoiding that a single tooth is meshed and stressed with the same tooth in a short meshing cycle and prolonging service life of gear transmission, compact in structure, small in size, attractive in appearance, high in rigidity, capable of achieving the blending function that large torque is transmitted by small power, and low in manufacturing cost.
Description
Technical field
The utility model relates to a kind of uni-drive gear box, relates in particular to a kind of mixer power transmission gear box.
Background technique
Stirrer is mainly used in agricultural, engineering machinery a kind of machinery that plays agitating function, is a kind of high efficiency type.The uni-drive gear box of its use feels that major part is Multi-stage transmission, and volume is large and not attractive in appearance, and its use and maintenance cost is high in addition.
Summary of the invention
The purpose of this utility model is to provide a kind of mixer power transmission gear box, and this gear box structure is compact, volume is little, handsome in appearance, stable drive, adequate rigidity, can realize the agitating function of small-power transmitting large torque, and low cost of manufacture.
The utility model is achieved like this, it comprises that it comprises bevel gear shaft, small end cover, large spiral shell umbrella, casing, case lid, spline output shaft, spline housing, it is characterized in that casing, case lid, small end cover adopt the round sealed combining structure, power meshes large spiral shell umbrella shape from right-hand member by bevel gear shaft and becomes larger reduction speed ratio, increases and turns round rear large spiral shell umbrella internal spline connection spline output shaft, the spline housing output high pulling torque of passing through.
Described gear-box is single-stage spiral bevel gear pair uni-drive gear box, and gear pair is the two end supports structure, and velocity ratio is 7.75:1, and modulus is 5.1, the large spiral shell umbrella number of teeth 62, the bevel gear shaft number of teeth 8.
Technique effect of the present utility model is: 1, the single-stage driving gearbox drive more steadily effectively, spiral bevel gear pair has the number of teeth of larger mutual prime rwmber, can avoid single tooth always within very little mesh cycle with same tooth engaging stress, improve the gear transmission life-span; 2, casing, case lid are the round sealed combining structure, and structural design is compact, volume is little, handsome in appearance; 3, the spiral bevel gear pair big retarding is than 7.75:1, and modulus 5.1 and be the layout of two end supports structure has strengthened the gear box structure rigidity, can realize the agitating function of small-power transmitting large torque, and low cost of manufacture.
The accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Bevel gear shaft 2, small end cover 3, large spiral shell umbrella 4, casing in the drawings, 1,
5, spline output shaft 6, case lid 7, spline housing.
Embodiment
As shown in Figure 1, the utility model is achieved like this, it comprises bevel gear shaft 1, small end cover 2, large spiral shell umbrella 3, casing 4, spline output shaft 5, case lid 6, spline housing 7.It is characterized in that casing 4, case lid 6, small end cover 2 adopt the round sealed combining structure, power forms big retarding than 7.75:1 from right-hand member by the large spiral shell umbrella 3 of bevel gear shaft 1 engagement, realizes increasing after turning round the internal spline that passes through again large spiral shell umbrella 3 and connects spline output shaft 5 and spline housing 7 output high pulling torques.The utility model is one-level spiral bevel gear pair uni-drive gear box, large spiral shell umbrella 3 numbers of teeth are 62, bevel gear shaft 1 number of teeth is 8, have the larger mutual prime rwmber number of teeth, can avoid single tooth always within very little mesh cycle with same tooth engaging stress, and a pair of spiral bevel gear pair modulus is 5.1, is again the two end supports structure, be well positioned to meet so the powerdriven requirement of stirrer of 40 horsepowers of inputs and the output of 4030N.M high pulling torque.
