Coolant delivery system and skiving machine equipped with the system

摘要

A coolant delivery system which serves to deliver a cooling agent whose purpose is to carry away the heat that is generated in the process of machining a toothed profile by means of a skiving wheel rotating about its rotary axis. The coolant delivery system provides for a delivery path section which, seen in a projection onto a plane extending orthogonal to the rotary axis, is arranged closer to the axis than the toothed profile of the skiving wheel and has a dimensional component in the axial direction.

1. Coolant delivery system for the delivery of a cooling agent that serves to carry away the heat generated in the skiving of a toothed profile by means of a skiving wheel (2) rotating about its rotary axis (C2), said skiving wheel including tooth profiles (4) and having a far side defined by cutting surfaces (10) with respective cutting edges,
characterized by a first delivery path section which, with respect to a projection of said first delivery path section onto a plane extending orthogonal to the rotary axis, is arranged closer to the rotary axis than the toothed profile (4) of the skiving wheel and has a first coolant delivery path component in the axial direction of said rotary axis, said first coolant delivery path component extending in the axial direction to radially directed outlets, said outlets being located axially beyond said far side of said skiving wheel, said coolant delivery system comprising a second delivery path section having a second coolant delivery path component extending in an outward radial direction relative to said rotary axis, said first coolant delivery path component being in fluid communication with said second coolant delivery path component via said radially directed outlets, wherein at least a part of the second delivery path section is delimited by a barrier shield arranged axially beyond said far side of said skiving wheel, said barrier shield having a shape of one of a cone or a surface segment of a sphere whereby cooling agent will flow along an inside surface of said barrier shield and be directed toward said cutting surfaces.
