CONSTITUTION:On the top and the bottom side of a flat endless belt 1 in which tensile rope members, having low ductility and high tenacity, are embedded in spiral and parallel to each other in a rubber-like elastic material, cog-shaped reinforcing members 5 are located on the bottom side and reinforcing plates 6 on the top side so that they are positioned in a direction extending orthogonal to the longitudinal direction of a belt and facing each other, and the reinforcing plate on the top side and the reinforcing material on the bottom side are tightened and secured together by means of fastening materials 7 such as bolts which pierce through the flat belt 1. The cog-shaped reinforcing material 5 is formed in the shape of a cog by a metal, a resin, an FRP, a wood, or a plywood rod or pipe, with high rigidity, and the reinforcing plate 6 is made of a metal plate, a resin plate, or FRP.

Description

[Detailed description of the invention]

The present invention relates to a V-belt for power transmission, particularly a V-shaped cog belt for dynamic load movement, which has high lateral pressure resistance.
It is. Conventionally, V-shaped cog belts for power transmission have been manufactured by laminating and pasting rubberized canvas to upper and lower cushion rubber layers RUn in which lobe tensile members are buried in parallel, and creating a wave-like 0] cog on the lower part of the belt, that is, the contact surface with the pulley. Since the group is provided, it has good flexibility, but on the other hand, when the cog part glue joint rubber is usually flexible and the boule relay is fitted and driven, there is no damage to the entire belt or the blade. There are problems such as deformation and falling into the pulley, resulting in a gradual decrease in speed and early damage due to deformation. For this reason, various countermeasures have been taken to date to improve the lateral pressure resistance, but no satisfactory countermeasure has yet been obtained. In response to this current situation, the applicant has also been working on solving the cog belt σJ problem Fff as shown above, and has been working on various θ]
After repeated research, he proposed in Utility Model Application No. 1987-68793 that the lateral pressure resistance could be improved by inserting a metal vibrator or rod with high belt cog properties into the belt. However, he thought about it further and said,
If you insert a metal rod or a metal vibrator into the cog,
+ When the force is applied, shear force, tensile J force, and soil shrinkage 1 force are applied to the thin rubber layer between the tensile lobes and their reinforcement members, and the rubber is torn due to mechanical fatigue, thermal fatigue, oil, etc. It turns out that there is a problem when the reinforcing material falls off. Moreover, all the metals inserted in the above proposal are 1

When surface 10 G is exposed, it is necessary to lubricate from the outside 311. If the lubricating oil is not applied correctly, friction between the reinforcing metal of the belt and the metal 1/sight pulley will cause noise while the belt is being carried. 1? [0] Not only does it cause wear and tear, but it also generates heat and creates a seizure hole. Therefore, it is desirable to lubricate from the outside, but depending on the application, oil lubrication is avoided if there are hygiene problems, such as those related to food. It has also been found that in such a case (σ), even with the above method, θI is no longer convenient. That is, the present invention focuses on the above-mentioned situation, and

The purpose of the proposed invention is to prevent the above drawbacks, especially the former drawback, and to provide an improved V-belt for high-load transmission. Therefore, in order to quickly form the object of the present invention, a flat belt is intended to be used, and a reinforcing plate is placed on the upper part of the flat belt, and a cog-shaped reinforcing material is placed oppositely on the lower part of the flat belt. Reinforcement plate using anchoring phase such as. The flat belt penetrates through the reinforcing material and is integrally tightened. Here, a flat endless belt in which a flat belt (low elongation, high strength θ) lobe tensile bodies are embedded in parallel in a rubber-like elastic body in a spiral manner, and a canvas layer with one to several layers on the surface This includes both flat endless belts laminated and pasted.Of course, jl■?ft in the latter case σJ of 06
It is also important to prevent the above drawbacks, and for this purpose, first of all, use a porous sintered structure that has self-lubricating properties. Separately proposed.

Regarding the case of a flat belt embedded in a shaped elastic body and having a canvas layer k (L' layer) attached to both the upper and lower surfaces, it is of course a flat belt that does not have a canvas layer on the lower and lower sides, that is, a lobe. The same applies to the case of a flat bell in which a tensile member is spirally embedded in a rubber-like elastic body, and the fastening mode using bolts etc. σ] fastening 42 is also the same.

As described above, the power transmission V-belt of the present invention has a puffer part formed of a cog-shaped reinforcing material, and aluminum or an aluminum alloy attached to this. In addition to using reinforcing materials such as metal rods of When mated, there is no belt lateral deformation (Q), improving lateral pressure resistance compared to conventional cog belts, and the deformation prevention effect increases the transmission force per the same cross-sectional area. Moreover, by fixing the reinforcement A to the reinforcing plate with bolts, etc., the shearing force generated between the reinforcement and the tensile lobe, which was a problem in the past, can be reduced. Most of the material is supported by the reinforcement I and the fastening hole that penetrates the reinforcing plate, and by dispersing the shearing force, the cog part glue and J breakage are eliminated, the reinforcement material is prevented from falling off, and the side part is resistant. ffiEσ〕1 step θ】
