Abstract
A horizontal hobbing machine comprises a bed, a cutting section provided on the bed and including at least a horizontal rotary shaft and a hob. The cutting section generates a tooth form on a work piece supported around the rotary shaft by means of the hob. A conveyor is provided in a lower part of the cutting section below the bed to remove chips of the work piece resulting from the cutting process.
Claims8
A dry-cutting type horizontal hobbing machine comprising:
- a bed;
- a dry-cutting section provided on said bed and including at least a horizontal rotary shaft and a hob, said dry-cutting section generating a tooth form on a work piece supported around said rotary shaft by means of said hob, so as to perform dry cutting;
- a conveyor provided in a lower part of said dry-cutting section below said bed, said conveyor having a direction of conveyance which is perpendicular to an axial direction of said rotary shaft;
- and
- an opening formed in said bed beneath said dry-cutting section through which cut chips drop from said dry-cutting section onto said conveyor, wherein said opening has a first opening dimension, in a direction along the axial direction of said shaft, which is larger than a second opening dimension, in a direction along the direction of conveyance of said conveyor.
A dry-cutting type horizontal hobbing machine comprising:
- a bed;
- a dry-cutting section provided on said bed and including at least a horizontal rotary shaft and a hob, said dry-cutting section generating a tooth form on a work piece supported around said rotary shaft by means of said hob, so as to perform dry cutting;
- a belt conveyor for exhausting cut chips from the dry-cutting section, said belt conveyor being provided in a lower part of said dry-cutting section below said bed, and said belt conveyor having a direction of conveyance which is perpendicular to an axial direction of said rotary shaft and wherein said belt conveyor is a first conveyor and further comprising a second conveyor for receiving cut chips from said first conveyor and for further conveying the cut chips in a direction parallel to the axial direction of said shaft.
