Abstract
The utility model relates to a kind of poly Vbelt belt pulley, comprise belt pulley, belt pulley comprises foreign steamer and wheel hub former, it is characterized in that, foreign steamer is roughly thin walled cylinder, and its outer wall is provided with multiple wedge slot tooth, wheel hub former is in one end of foreign steamer, substantially be lamellar, stiffening plate and wheel hub former weld together, and stiffening plate is in the central position of wheel hub former.The belt pulley of the utility model poly Vbelt belt pulley can be manufactured by sheet metal spinning, welds stiffening plate and improve bearing capacity on wheel hub former, and simple in structure, lightweight, material is economized, and manufacturing efficiency is high, balance quality is good.
Description
Technical field
The utility model relates to belt pulley technical field, relates to or rather a kind of poly Vbelt belt pulley.
Background technique
The advantages such as poly Vbelt belt pulley has that velocity ratio is large, long service life, stable drive and driving force abundance, be widely used on internal-combustion engine, nearly all motor vehicle with internal-combustion engine all adopt " snakelike " transmission system of multi-rib-belt, realize bent axle and drive various car accessories, as engine blower, power steering pump, air conditioning pump, air-conditioning unit and alternator etc.From design angle, poly Vbelt can make its belt wheel pitch diameter reduce, and can increase thus the quantity of the annex that drives with positive and negative wedge surface driving pulley, has both saved space, does not reduce again power.Therefore, on Foreign Automobile, mostly adopt poly Vbelt to drive motor front-end wheel system at present.But existing poly Vbelt belt pulley is all complex structure, quality weight mostly.
Summary of the invention
The purpose of this utility model is, a kind of simple in structure, lightweight, poly Vbelt belt pulley of saving material is provided.
To achieve these goals, the technical solution adopted in the utility model is: a kind of poly Vbelt belt pulley, comprise belt pulley, belt pulley comprises foreign steamer and wheel hub former, it is characterized in that, foreign steamer is roughly thin walled cylinder, its outer wall is provided with multiple wedge slot tooth, and wheel hub former, in one end of foreign steamer, is lamellar substantially, stiffening plate and wheel hub former weld together, and stiffening plate is in the central position of wheel hub former.
The belt pulley of the utility model poly Vbelt belt pulley can be manufactured by sheet metal spinning, welds stiffening plate and improve bearing capacity on wheel hub former, and simple in structure, lightweight, material is economized, and manufacturing efficiency is high, balance quality is good.
Accompanying drawing explanation
Fig. 1 is the sectional view of the utility model poly Vbelt belt pulley.
Below in conjunction with accompanying drawing, the utility model is described in detail.
Embodiment
Referring to Fig. 1, poly Vbelt belt pulley comprises belt pulley, and belt pulley comprises foreign steamer 11 and wheel hub former 12, and foreign steamer 11 is roughly thin walled cylinder, and its outer wall is provided with multiple wedge slot tooth 13.Wheel hub former 12, in one end of foreign steamer, is lamellar substantially.Belt pulley first adopts process for stamping base by the metal blank of 3.5mm, then on spinning machine, shapes.By to have the sheet metal rotation of plastic deformation or mobile performance make it force bearing point by putting line, by line to face, in certain direction, give certain pressure simultaneously and make metallic material along this Direction distortion and flow the belt pulley shape that reaches required.When belt pulley is made, material streamline is not cut off, and surface is by flow harden, and tissue density improves, and the intensity of wheel rooved face is high, and dimensional accuracy is high, makes that the belt transmission of matching running is steady and driving force is sufficient, the life-span is long.
Stiffening plate 2 welds together with wheel hub former 12, and stiffening plate 2 is in the central position of wheel hub former 12.Stiffening plate 2 is by the stamping part of No. 20 steel plate material punching one-tenth of 4mm, is welded on the bearing capacity that can improve poly Vbelt belt pulley on wheel hub former 12.
Poly Vbelt skin belt pulley of the present utility model, simple in structure, lightweight, material is economized, is a kind ofly to save material, environmental protection, energy-conservation new product, and manufacturing efficiency high (2～4 of processing per minute), balance quality is good, without Balance Treatment.
