Title:
A dressing device and a gear grinding device
Document Type and Number:
Japanese Patent JP5984615
Kind Code:
B2
Abstract:
This dressing device has: a gear grinding tool spindle (7) that rotatably supports a screw-shaped grindstone (10); and a dressing tool (30) that dresses the screw-shaped grindstone (10). The dressing device dresses the screw-shaped grindstone (10) by driving the screw-shaped grindstone (10) to rotate, and causing the relative motion of the screw-shaped grindstone (10) and/or the dressing tool (30). The dressing device performs a dressing process on the screw-shaped grindstone (10) in a manner such that the pressure angle changes along the direction of the tooth line by means of moving the screw-shaped whetstone (10) and/or dressing tool (30) at a fixed speed and altering the speed of rotation of the screw-shaped grindstone (10), or rotating the screw-shaped grindstone (10) at a fixed speed and altering the speed of motion in the axial direction of the screw-shaped grindstone (10) and/or the dressing tool (30).
