Abstract
A transmission pulley, for a power transmission system including a belt having longitudinal grooves, having at least one end cap, a stack (E) of identical crowns, as well as means of connecting the crowns and the cap, parallel to a rotational axis (X10) of the pulley and rotating about this axis. The cap defines a hollow housing wherein half of the adjacent crown is engaged on one side of a median plane of the crown.

A transmission pulley for a power transmission system including a belt having longitudinal grooves, comprising:
- at least one end cap,
- a stack (E) of identical crowns,
- means of connecting crowns and the cap, parallel to a rotational axis (X10) of the pulley and rotating about this axis, wherein
- the cap defines a hollow housing in which half of the adjacent crown is engaged on one side of a median plane of this crown.
The power transmission system (S) for a rotating part of an automobile engine, comprising:
- a belt having longitudinal grooves as well as rotary pulleys, wherein at least one of the pulleys includes at least one end cap, a stack (E) of identical crowns, means of connecting crowns and the cap, parallel to a rotational axis (X10) of the pulley and rotating about this axis, wherein the cap defines a hollow housing in which half of the adjacent crown is engaged on one side of a median plane of this crown.
A method for producing a transmission pulley for a power transmission system (S) a belt having longitudinal grooves as well as rotary pulleys, wherein at least one of the pulleys includes at least one end cap, a stack (E) of identical crowns, means of connecting crowns and the cap, parallel to a rotational axis (X10) of the pulley and rotating about this axis, and wherein the cap defines a hollow housing in which half of the adjacent crown is engaged on one side of a median plane of this crown;
- and comprises the following steps:
- a) determining the number of longitudinal grooves of the belt,
- b) forming a stack (E) of identical crowns with a number of crowns selected depending on the number of grooves of the belt, and
- c) connecting the stack (E) of crowns with at least one end cap.
