Abstract
In a belt transmission apparatus utilized between an engine of a motorcar and an auxiliary apparatus thereof, a pulley groove angle .theta. of V-belt pulleys is set in the range of 45.degree. to 60.degree., where slip of the belt easily occurs. A belt angle .alpha. between both sidefaces of the V-belt is set in the range determined by the inequality .theta.-7.ltoreq..alpha..ltoreq..theta. with respect to the pulley groove angle .theta..
Claims6
A belt transmission device for use in an engine of a motorcar, said belt transmission device comprising:
- a driving pulley for mounting on a crankshaft of an engine, said driving pulley having a first V-shaped pulley groove with a first pulley groove angle .theta. of 45.degree.-60.degree.;
- a driven pulley for mounting on a driving shaft of an auxiliary device of the engine, said driven pulley having a second V-shaped pulley groove with a second pulley groove angle .theta. of 45.degree.-60.degree.;
- and
- a belt trained between said driving pulley and said driven pulley, said belt having a pair of inclined sidefaces in a V-shape, said inclined sidefaces having a predetermined angle therebetween, to engage said V-shaped pulley grooves of said driving pulley and said driven pulley.
A belt transmission device for a diesel engine and an auxiliary device to be driven by the diesel engine, said belt transmission device comprising:
- a driving pulley mounted on a crankshaft of the engine, said driving pulley having a first V-shaped pulley groove with a first pulley groove angle .theta. of 45.degree.-60.degree.;
- a driven pulley mounted on a driving shaft of the auxiliary device of the engine, said driven pulley having a second V-shaped pulley groove with a second pulley groove angle .theta. of 45.degree.-60.degree.;
- and
- a belt trained between said driving pulley and said driven pulley, said belt having a pair of inclined sidefaces in a V-shape, said inclined sidefaces having a predetermined angle therebetween, to engage said V-shaped pulley grooves of said driving pulley and said driven pulley.
A belt transmission device for a diesel engine having an automatic speed-shifting gear and an auxiliary device to be driven by the diesel engine, said belt transmission device comprising:
- a driving pulley mounted on a crankshaft of the engine, said driving pulley having a first V-shaped pulley groove with a first pulley groove angle .theta. of 45.degree.-60.degree.;
- a driven pulley mounted on a driving shaft of the auxiliary device of the engine, said driven pulley having a second V-shaped pulley groove with a second pulley groove angle .theta. of 45.degree.-60.degree.;
- and
- a belt trained between said driving pulley and said driven pulley, said belt having a pair of inclined sidefaces in a V-shape, said inclined sidefaces having a predetermined angle therebetween, to engage said V-shaped pulley grooves of said driving pulley and said driven pulley.
