Description
Technical field:
The utility model relates to the belt pulley in a kind of mechanical transmission component, particularly a kind of composite spinning belt sheave.
Background technique:
The V-shaped groove belt pulley is as important mechanical transmission component, be widely used in automobile, farm machinery, on the various mechanical transmissions such as textile manufacturing machine, wherein, the application of Composite Skin belt wheel also more and more widely, this belt pulley has the unequal V-shaped groove of twice diameter, traditional Composite Skin belt wheel all is to adopt cast blank to make through the method for cutting, this belt pulley not only wall thickness is thicker, integral body is relatively heavier, and in course of working, to remove a large amount of metallic material, wasted material, (sand holes have been arranged because castability is inhomogeneous, pore etc.), so each belt pulley all need carry out Balance Treatment, thereby manufacturing efficiency is low, and cost is higher; At present, along with updating of Composite Skin belt wheel production technology, someone adopts earlier big V-shaped groove, little V-shaped groove processes respectively with the method for spinning, and then they are welded on respectively on the good bearing block of machining (referring to Fig. 3), the belt pulley that this method makes and traditional casting belt wheel compare have in light weight, good product quality, advantages such as beautiful shape, but still there is following shortcoming in it: (1), welding easy deformation: because this product is with good big of spinning, little V-shaped groove is welded on the bearing block respectively, and good big of spinning, little V-shaped groove wall thickness generally only is 1.5～2.5mm, compares easy deformation when therefore welding; (2), because the bearing spider of this product is to adopt mach method processing, still will remove metallic material, so its cost of production is still higher relatively.
The model utility content:
The technical problems to be solved in the utility model is: provide a kind of not yielding, composite spinning belt sheave that cost of production is low, to solve the problems referred to above that present Composite Skin belt wheel exists.
The technological scheme that solves the problems of the technologies described above is: a kind of composite spinning belt sheave, it constitutes an integral body for five sections by the big vee-belt groove, dish-shaped former, carrying cylinder, the little vee-belt groove that connect successively and the mounting plate that is positioned at belt pulley small end end face, described big vee-belt groove one end is the large end face of belt pulley, the other end is connected with the excircle of dish-shaped former, and the inner circumference of dish-shaped former is tilted to down and is connected with an end of carrying cylinder towards the big extreme direction of belt pulley; Described carrying cylinder is inwardly shrinking formation one concave station rank near little vee-belt groove end, its endoporus also forms a step hole; Little vee-belt groove is connected with the concave station rank of carrying cylinder on one side, and another side is connected with the cylindrical of mounting plate; Described mounting plate is made of the circular mounting plane middle with being positioned at this dish plane, dish-shaped plane, and a center hole is arranged on the circular mounting plane; Above-mentioned each joint is rounding off and connects.
Described big vee-belt groove outer diameter D with the span of the ratio D/d of little vee-belt groove outside diameter d is: 1≤D/d≤3.
Further technological scheme of the present utility model is: described belt pulley is to adopt Cold Rolled Sheet Steel to form through the method manufacturing of continuous drawing, rotary press modelling.
The composite spinning belt sheave of the utility model is compared with existing Composite Skin belt wheel, has following beneficial effect:
1, product is not yielding, the quality height:
Because big vee-belt groove, little vee-belt groove and the carrying cylinder of the composite spinning belt sheave of the utility model form an integral body by Cold Rolled Sheet Steel through continuous drawing, spinning operation, avoided because the distortion that welding causes, and have higher surface finishment and surface hardness by the race of this belt pulley after the spinning operation, therefore, its quality of product is higher.
2, cost of production is low:
Because the composite spinning belt sheave of the utility model is to form with Cold Rolled Sheet Steel carries out rotary press modelling again behind continuous drawing method manufacturing, whole course of working need not be removed metallic material, not only conditions of manufacture is good, saved material, nor need carry out Balance Treatment, thereby the manufacturing efficiency height, cost of production is lower.
3, product size precision height:
Because the big vee-belt groove of the composite spinning belt sheave of the utility model and little vee-belt groove are to form like this: the big vee-belt groove of first spinning, the interior step hole of pre-then railway carriage belt wheel carrying cylinder, locate the little vee-belt groove of spinning with the interior step hole of carrying cylinder more at last; This processing method can guarantee the dimension precision requirement between the large and small V-shaped groove, so this dimensional accuracy of products height.
4, intensity is good, the profile better appearance:
Because the composite spinning belt sheave of the utility model is in the joint of big vee-belt groove and dish-shaped former, all have stiffening rib in the joint of little vee-belt groove and mounting plate, increased wall thickness in the corner joint, that has avoided being easy to generate because of corner is excessive loses, thereby its intensity is better, and, be rounding off in each section joint of this belt pulley and connect, so this belt pulley profile better appearance.
Below, the technical characteristics to the composite spinning belt sheave of the utility model is further described in conjunction with the accompanying drawings and embodiments.
