Description
Technical field
The utility model relates to a kind of High Speed Light belt pulley, particularly Vee pulley V.
Background technique
Existing Vee pulley V, normally the outer surface at the belt pulley wheel rim processes the triangle trough of belt of at least one circle around circumference with method for turning, during use v belt is nested in the triangle trough of belt, drive belt pulley by v belt by frictional force and rotate (perhaps driving v belt by belt pulley moves), thereby reach the purpose of transmission.In transmission process, v belt is out of shape on the triangle trough of belt of belt pulley, rubs and produces heat, these heat accumulations particularly concentrate on belt pulley and reach on the belt in the triangle trough of belt, be not easy to distribute, v belt is operated under the environment of high temperature throughout the year, has shortened its working life greatly.In order to solve the problem of heat radiation, someone finds out and utilizes radial cut to offer the radially way of straight joint in the bottom of triangle trough of belt, these radially straight joint extend to the internal surface of wheel rim always, make heat to distribute to the internal surface of wheel rim from straight joint radially, though do the problem that has solved heat radiation like this, but adopt radial cut to offer radially straight joint in the bottom of triangle trough of belt, the comparatively difficulty that operates, and very bother.
The model utility content
In order to solve existing in prior technology the problems referred to above, the utility model provides a kind of High Speed Light belt pulley, it can utilize simple method fast to form the radially straight joint that is communicated to the wheel rim internal surface in the bottom of triangle trough of belt, when solving belt pulley heat radiation cooling problem, alleviated the weight of belt pulley, belt pulley can be used in the occasion that runs up, but also have easy to process, simple and reasonable advantage.
The technical solution of the utility model is to constitute like this, it comprises wheel rim, the outer surface of wheel rim is provided with the triangle trough of belt of at least one circle around circumference turning processing, the bottom of triangle trough of belt is provided with many along the equally distributed radially straight joint of circumference, these radially straight joint extend to the internal surface of wheel rim always, it is characterized in that: the internal surface of wheel rim is provided with many along the equally distributed groove of circumference, there is suitable distance the bottom of groove to the bottom of triangle trough of belt, so that after adopting method for turning processing triangle trough of belt, form radially straight joint automatically at vee belt groove bottom and bottom portion of groove intersection.
The utility model can adopt the method for casting to form many along the equally distributed groove of circumference at the internal surface of wheel rim in advance, and because there is suitable distance the bottom of these grooves to the bottom of triangle trough of belt, therefore after utilizing turning method for processing processing triangle trough of belt, can form radially straight joint naturally at vee belt groove bottom and bottom portion of groove intersection.Than prior art, the utility model High Speed Light belt pulley has following advantage: the one, be provided with many at the internal surface of wheel rim along the equally distributed groove of circumference, wheel rim position quality is reduced, in economical with materials, can reduce whole centrifugal force when running up; The 2nd, can adopt with processing the common nothing method that radially the straight joint belt pulley is identical and process, therefore need not to adopt special processing method, need not to increase manufacturing procedure, and need not to increase manufacture cost; The 3rd, the radially straight joint that is processed to form makes belt pulley have refrigerating function preferably when work, our experiments show that, there is not radially the traditional triangle belt pulley of straight joint compare with triangular groove bottom, use this belt pulley can make the temperature of belt reduce 10-15 ℃, therefore not only help the stability of the work of guaranteeing, and can prolong the working life of belt greatly; The 4th, owing to have advantage one and advantage three, make belt pulley to use in the occasion that runs up, can bring up to linear velocity more than 50 meter per seconds from 30 common meter per second linear velocities.
In the technique scheme, for fear of adopt independent core when casting, from axial direction, described groove is a trench structure.
Above-mentioned groove is other while leading to from wheel rim in the axial direction.
In order to ensure the balance of the heat radiation all even belt wheel of cooling own,, there is abundant radially straight joint to be evenly distributed on the circumference from circumferencial direction.
In order to make the attachment portion keep enough intensity, from circumferencial direction, radially the length of straight joint preferably and its gap adapt.
From circumferencial direction, radially the length of straight joint is 7-30mm, and radially the length of straight joint is preferably 12-25mm.Certainly according to the size of diameter pulley, radially the length of straight joint can suitably be adjusted.
For fear of in movement process radially straight joint belt is caused wearing and tearing or destroys, above-mentioned groove has suitable radial depth, the bottom that is arranged in the belt of triangle trough of belt when avoiding turning round touches the radially outside of straight joint.

Embodiment
Below in conjunction with specification drawings and specific embodiments the utility model content is elaborated:
Be the utility model embodiment as Figure 1-3, it is a kind of founding type Vee pulley V, by three spokes 6 (can do the spoke more than three during actual the manufacturing as required) and wheel hub 7, and wheel rim 1 be formed by connecting.During casting, the internal surface 12 of wheel rim forms many grooves 4, and above-mentioned groove is evenly distributed between the spoke along circumference.In the axial direction, groove 4 is trench structure, while other from extending to of wheel rim 1.At the outer surface 11 of wheel rim, process four triangle troughs of belt 2 (can process more or less triangle trough of belt according to the width and the diameter of wheel rim during actual fabrication, but have at least) with turning.
Because groove 4 has proper depth, when turning triangle trough of belt 2, form radially straight joint 3 naturally in the bottom 21 of triangle trough of belt and the intersection, bottom of groove.In other words, the bottom 41 of groove 4 is arranged in the outside of the bottom 21 of triangle trough of belt in a circumferential direction.In order to explain this viewpoint, the bottom 21 of triangle trough of belt is pointed out with the some lead-in wire in Fig. 1, and is made local amplify (as Fig. 3).
As shown in Figure 2, because groove 4 has suitable radial depth, the outside 31 of the radially straight joints 3 that processing triangle trough of belt 2 backs form is in belt 5 below of (dotted line is represented), and therefore, the bottom 51 that can prevent belt 5 touches the outside 31 of straight joint 3 radially and destroyed.Be provided with an axial taper hole (also can be the straight hole of band keyway as required) in the wheel hub, it can cooperate tapered sleeve this belt pulley to be installed on the axle (if straight hole, then need key).
From circumferencial direction, there is abundant radially straight joint to be evenly distributed on the circumference.
From circumferencial direction, radially the length of straight joint and its gap adapt, and wherein length is that 7-30mm is better, and length is 12-25mm better (radially the length of straight joint can be carried out suitable adjustment according to the size of belt pulley certainly).
Above-described Vee pulley V is processed by foundry goods, and this foundry goods can adopt any casting method, such as adopts expendable mo(u)ld or permanent mould.And foundry goods can be with any metal or ferro-alloy.Yet reasonable foundry goods forms by sand casting process with high strength cast iron.
The surface that needs in the Vee pulley V to process is: the periphery that the triangle trough of belt reaches, the side of wheel rim, center hole, the side of wheel hub etc.
Under the satisfiable condition of cool condition, the more special advantage of belt pulley of the present utility model is to match with the narrow v belt of a lot of types, such as SPA, SPZ, SPB, SPC class can certainly match with the vee belt of other types.
