Abstract

See full text

A counterweight for use in a cone crusher that includes an inner oil chamber and an outer oil chamber to collect lubricating oil during operation of the cone crusher. The counterweight includes a vertical separating wall that receives a splash shield. The vertical separating wall and splash shield define an inner oil chamber while an outer oil chamber is defined by the splash shield, the vertical separating wall and an inner wall of the counterweight. Both the inner and outer oil chambers include drain holes that allow lubricating oil to pass through a generally horizontal floor of the counterweight. The combination of the inner and outer oil chambers allows oil to quickly exit the counterweight into the main oil sump and reduces the amount of oil that gets exposed to the upper seal assembly which reduces the passage of oil past seal assemblies formed in the cone crusher.
