Ontology of pulley drive event.

Number	Proposition in the ontology
1	Inherits the ontology of the friction drive event.
2	Possesses the driving pulley with the diameter 𝐷1  and the rotational speed 𝑛1,  and 𝐷1>0,  𝑛1≥0.
3	Possesses the driven pulley with the diameter 𝐷2  and the rotational speed 𝑛2,  and 𝐷2>0,  𝑛2≥0.
4	Possesses N belts with the length L, and 𝑁≥1,  𝐿>0.
5	Works by the friction between the pulleys and belts.
6	Drive ratio is R.
6.1	𝑅=𝐷1/𝐷2.
6.2	𝑅=𝑛1/𝑛2.
