摩擦により発熱するため、これらベルト等を空気
によつて強制的に冷却する必要がある。 Conventionally, a belt power transmission device was developed in 1983 as a belt power transmission device comprising a cover and a case that are fixed to each other to form a gap chamber, and a pulley and a clutch that are attached to a common rotating shaft and arranged within the gap chamber. -165968 is publicly known. In this type of belt power transmission device, since the belt and pulley generate heat due to friction, it is necessary to forcibly cool these belts and the like with air.

てベルト等の冷却効率が悪くなるものである。 By the way, as mentioned above, the idea of forcibly cooling belts etc. with air is well known, but this idea can be applied to the above-mentioned pulley and clutch mounted on a common rotating shaft in a cavity chamber. When applied to a belt power transmission device of the installed type, a major issue is how to exhaust the cooling air, that is, where to provide the exhaust holes. This is because, as mentioned above, the pulley and clutch are mounted on a common shaft and placed in the cavity, so heat from the clutch side is easily transferred to the belt side wrapped around the pulley. , therefore, the cooling efficiency of the belt etc. deteriorates.

By fixing it to the holder, it becomes an exhaust passage 21 for cooling air as shown in FIG. A lower exhaust hole 22 that opens into the groove 19 is provided at the lower portion of the peripheral wall of the cover 7 on the driven pulley 12 side. The lower exhaust hole 22 is protected from muddy water and the like by a protector 23 which is protruding from the outer surface of the partition wall 20 and has openings on both left and right sides. The cover 7
An upper exhaust hole 24 opening into the groove 19 is provided on the clutch 13 side of the upper part of the peripheral wall. Therefore, the upper and lower exhaust holes 24, 22 are offset by a distance l1 in the axial direction of the rotating shaft 11 as shown in FIG. 2, and at an angle θ in the circumferential direction of the rotating shaft 11 as shown in FIG.

is cooled. This cooling air comes into contact with the cover 7,
Release heat to the outside. The cooling air thus guided to the rear of the gap chamber 6 contacts the pulley 12 and then contacts the clutch 13 by the action of the axial fan 13a of the clutch 13, thereby cooling the clutch 13.

ものとなる。 In this case, the cooling air in the gap chamber 6 is finally exhausted from the upper exhaust hole 24 deviated toward the clutch 13 side, through the exhaust passage 21, and into the atmosphere from the lower exhaust hole 22 of the partition wall 20. Because it is a thing, clutch 13
Heat from the side is not transferred to the belt 14 side, and the cooling efficiency of the belt 14 is increased. Further, since the upper exhaust hole 24 and the lower exhaust hole 22 are arranged offset from the axial direction and circumferential direction of the rotating shaft 11,
It is difficult for rainwater etc. to enter the void chamber 6, and the waterproofness is high.

Since the air is exhausted to the atmosphere through the air holes, heat from the clutch side is not transferred to the belt, resulting in high cooling efficiency for the belt. In addition, the cavity chambers are offset from each other in the axial and circumferential directions, and are communicated with the atmosphere through the lower ventilation hole and the exhaust passage, so it is possible to reliably prevent rainwater etc. from entering the cavity chamber. It has effects such as high waterproofness.
