[Related Art] Generally, it is said that meandering of a belt is caused not only by the material characteristics of the belt itself but also by adjustment on the pulley side and cannot be completely suppressed. It is known that a means for preventing meandering by adjusting the alignment of the pulley has difficulty in adjusting the alignment when the pulley has a cantilever structure, such as an automatic door, for example, and has difficulty in taking measures.

FIG. 4 shows an example of a structure used for preventing meandering of the belt. In the case of the example of this figure, the transmission is a belt transmission including a toothed belt 1 and a toothed pulley 2. That is, the rotational driving force is relatively transmitted by the meshing force between the teeth 3 of the toothed belt 1 and the teeth 4 of the toothed pulley 2. To prevent the toothed belt 1 from swaying and meandering in the width direction of the toothed pulley 2 during traveling, flanges 5 are coupled to both sides of the toothed pulley 2. The meandering is prevented by sliding the end faces.

[Problem to be Solved by the Invention] By providing the flange 5 as shown in FIG. 4, the initial purpose of preventing the toothed belt 1 from meandering is achieved. However, during operation, the toothed belt 1
Travel while contacting the flanges 5 on both sides, giving a discomfort to the surroundings due to the generation of contact noise,
Wear powder generated by contact scatters around and pollutes the environment. Therefore, it is not suitable for an assembly line for precision parts requiring quietness and a dust-proof environment, or an opening and closing mechanism for an automatic door as described above.

In general, black rubber or polyurethane rubber is known as a material of the belt. In the case of black rubber, noise generated by the contact with the flange 5 does not matter so much, but powder due to abrasion is considerable. Have an effect. Further, when made of polyurethane rubber, it is superior to black rubber in terms of abrasion resistance, but the contact noise is large, and both have such advantages and disadvantages.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a transmission pulley which has a structure in which belt meandering is prevented, abrasion resistance is improved, and noise generated by contact is suppressed.

[Means for Solving the Problems] The transmission pulley according to the present invention has an annular belt groove formed between a circumferential surface of the pulley and a peripheral end portion of the both-side flange, with flanges respectively connected to both side surfaces of the pulley. In the transmission pulley in which the belt travels in engagement with the belt, a plurality of annular grooves are formed concentrically on the inner surface of each peripheral end of both side flanges that contact both end surfaces of the belt, and between the annular groove and the annular groove. This is a configuration in which an annular ridge is formed.

[Operation] During operation, the belt runs while engaging with the annular belt groove. Since both end faces of the belt have annular grooves on the inner surfaces of the peripheral ends of the flanges on both sides, they do not contact the entire inner surface but only the annular ridge. In other words, the belt is restricted from moving in a meandering manner by coming into contact with the annular ridge during traveling. Further, since the contact is only with the annular ridge, the generation of the contact noise and the generation of the abrasion powder are all absent or minimized.

As shown in FIGS. 1 to 3, the pulley body 10 is in the form of a gear made of metal or synthetic resin having teeth 11 provided on its periphery. Disc-shaped flanges 20, 20 are coaxially connected to both side surfaces of the pulley body 10, respectively. As a method of connecting the flanges 20 and 20 to both sides of the pulley body 10, for example, adhesive bonding, caulking connection, or screwing connection can be considered.
The material of the flange 20 is, for example, a metal such as stainless steel. Considering that one of the gist of the present invention is to prevent powder generation on both side flanges 20 and 20 due to contact abrasion with the belt 30 described below, the material of the flange 20 is other than the above stainless steel. In particular, resins such as carbon fiber and nylon having a low coefficient of friction are effective. Further, a surface treatment material provided with a Teflon layer on the material is also effective.

The flange 20 is formed as a peripheral end 21 whose outer diameter is larger than the diameter (teeth diameter) of the teeth 11 of the pulley body 10. Therefore, the concave space between each peripheral end portion 21, 21 of the flanges 20, 20 on both sides and the teeth 11 of the pulley body 10 is formed as an annular belt groove A, and as shown in FIG. The belt 30 is engaged, and the teeth 32 formed on the main body 31 of the belt 30 mesh with the teeth 11 of the pulley main body 10. That is, if the illustrated transmission pulley is for driving, the rotation of the pulley body 11 is transmitted to the belt 30 by meshing the teeth 11 and the teeth 32, and if the illustrated transmission pulley is the driven side, the rotation of the belt 30 This is a rotating mechanism.

Further, as shown in the figure, a plurality of annular concave grooves 22 and 23 are formed concentrically on the inside of the peripheral end 21 of the flange 20, that is, on the inner surface facing and contacting both side surfaces 33 of the belt body 31. An annular ridge 24 is provided between the annular grooves 22 and 23. An annular ridge 25 is formed on the inner surface near the peripheral end 21. Therefore, the contact between the inner surface of the peripheral end portion 21 of the flange 20 and the side surface 33 of the belt 30 is only the annular ridges 24 and 25 on the flange 20 side or both of them.

Here, in the illustrated embodiment, two annular concave grooves 22 and 23 are provided on the inner and outer circumferences of concentric circles at the peripheral end 21 of the flange 20. As is apparent from FIG. 2, the side surface 33 of the belt 30 is normally in contact only with the annular ridge 24 on the flange 20 side and the annular groove 22 on the inner peripheral side. Looks like it's not there. However, by providing the annular concave groove 23 on the outer peripheral side, when the belt 30 competes during running in the state of FIG. 2, the contact of the side surface 33 of the belt 30 is caused only by the annular ridges 24 and 25. The area does not increase any more.

[Effects of the Invention] As described above, the transmission pulley according to the present invention is not only restricted from meandering by the flanges on both sides while the belt is running, but also on the inner surface of each peripheral end of the flanges on both sides. Since the annular groove is provided, the area where the both end surfaces of the belt come into contact with each other requires only a minimum annular ridge. Therefore,
The noise and abrasion powder generated due to the contact of the belt are not generated or minimized, and it is suitable for a quiet environment, a precision production line that dislikes the generation of dust, and the like.
