Abstract
The utility model discloses a hoop type belt pulley, which is composed of a wheel hub, belt spacing grooves, etc. The belt spacing grooves are composed of annular hoop groove plates which are positioned on the surface of the wheel hub and are perpendicular to a central axial cord. The utility model has the advantages of low manufacture cost and easy manufacture, and can be processed and produced by facilities in common medium and small factories.
Description
The utility model belongs to machinery, and especially the major diameter belt pulley is made the field.
General Vee pulley V all is a global formation, and wheel blank turning after casting processes the belt restraining groove.This structure is unchallenged for the processing of the belt pulley of minor diameter, but for major diameter or large diameter belt pulley, for example the diameter used of Production of Ceramics shredder is greater than two meters belt pulley, adopt this structure that difficulty of processing is increased greatly, processing charges increases, material expends and expends man-hour a lot ofly, and owing to will use special equipments such as large-scale vertical lathe toward contact, makes general middle-size and small-size factory be difficult to manufacture.
The purpose of this utility model is the belt pulley of a kind of new structure of design, and the manufacture difficulty that makes it the major diameter belt pulley reduces, and reduces production costs, and uses the equipment of general middle-size and small-size factory to produce.
The purpose of this utility model is to realize by following design.
Hoop formula belt pulley is made up of wheel hub and belt restraining groove etc., and described restraining groove is by standing on hub surface and being constituted with the perpendicular circumferential band frid of its central axis.
After adopting design as above, be divided into two major components in the making that adds whole belt pulley in man-hour: a part is for serving as the drum segment of wheel hub, and another part is the circumferential band frid that is divided into multistage.Circumferential band frid segmentation processing is assembled at last and forms the belt pulley restraining groove on the outer surface of cylinder and draw the pine back to produce axial motion to stop belt.Obviously, adopt structure of the present utility model, avoided the complicated processing to heavy castings, the manufacture difficulty of major diameter belt pulley is reduced, cost of production reduces, and the equipment of general middle-size and small-size factory can be produced.
Description of drawings is as follows:
Fig. 1 is the structural drawing of the utility model typical structure.
Fig. 2 is the sectional view of Fig. 1
Below in conjunction with accompanying drawing structure of the present utility model is described in further detail.
Can see that in Fig. 1 and Fig. 21 is cylinder, 2 and 3 is the side plate that places in the cylinder, On the hub surface vertical have the perpendicular circumferential band frid of number and the axis L of centre of the drum (such as 4,5 among the figure, 6) consist of several V belt stopper slots (such as 7,8 among the figure, 9). The circumferential band frid can adopt The modes such as welding, riveted joint are stood on the cylinder. Add man-hour actual, the circumferential band frid adopts has ladder The dull and stereotyped roll bending of shape groove is bent into the garden arcuation, again with its sectional on cylinder, during assembling to roll The tube axle center is benchmark campus, fixing, forms at last the belt stopper slot. Certainly, can be with the circumferential band frid Do compactly, gap to each other is as far as possible little.
Embodiment: with D type 8 groove diameter 3.12M belt pulleys is example, and cost decline situation is described:
Adopt integrated type: HT250 blank 6000-7000 unit; Cutting (5232 garden car) processing charges 4000-5000 unit, cost accounting 10000-12000 unit.
Adopt the utility model structure: a235 sheet material (thick 45mm), 15 of hoop frids, feed consumption 3000-3500 unit; 650 planers processing dovetail groove, the fixing processing charges 2000-3000 unit of welding behind the curved assembling of the plate bending rolls volume campus, cost accounting 5500-6500 unit reduces closely half.
Claims (2)
