Abstract

PURPOSE:To enable a clutch housing and a V-pulley to be manufactured in a large quantity to uniform quality, by molding one halved part of the V-pulley integrally with the clutch housing by sheet metal working while the other halved part independently by sheet metal working and welding the both halved parts to each other. CONSTITUTION:A clutch housing 18 is molded by sheet metal working, while the clutch housing both integrally molds in its side wall one halved part 7a of a V- pulley 7 and rotatably supports a part of the V-pulley 7 to a crankshaft 4 through a bearing 19. Further the other halved part 7b molded separately by sheet metal working is welded to said halved part 7a, and the pulley 7 is formed by the both halved parts. Accordingly, the clutch housing and the V-pulley of uniform quality can be manufactured in a large quantity further easily because generation of unreasonable stress is eliminated in the clutch housing when it is molded.

However, when trying to mold an integrated product with a clutch housing and a V-pulley from a single sheet metal,
■The side wall surface of the pulley located on the opposite side to the clutch housing side undergoes plastic deformation that is bent outward in the radial direction and further extends in the circumferential direction. Under stress, the wall thickness becomes too thin and cracks begin to appear. Therefore, it is extremely difficult to mass-produce products of uniform quality from sheet metal.

The above-mentioned V pulley with clutch housing is V pulley 7.
is divided into two half parts 7a and 7b, and only one half part 7a is molded from sheet metal integrally with the clutch housing 18, and the other half part 7b is molded independently from this clutch housing 18. I try to do that. Therefore, when the clutch housing and the V pulley are press-formed from sheet metal at the same time, considerable stress is generated on the side wall portion of the V pulley opposite to the clutch housing side, that is, the side wall portion corresponding to the half portion 7b. There is no problem in letting it happen.

As mentioned above, the V-pulley with clutch housing of the present invention has two parts: (i) one half of the pulley is molded integrally with the clutch housing from a sheet metal, and the other half is molded from a sheet metal independently from the clutch housing; However, since the two halves are welded together to form a V-pulley, the other half (the side wall of the V-pulley opposite to the clutch housing side) is free from undue stress. It is possible to mold the product, which makes it possible to mass-produce products of uniform quality even though they are made of sheet metal.
