What is the main reason for the radial runout tolerance of gear ring?
There are many reasons for the radial runout error of gear ring. The main cause of the radial runout error of gear ring is the geometric eccentricity, that is the gap between the hole of the gear blank and the mandrel of the fixture. If the production of small batch, with as little as possible gap fit (gear hole and mandrel); if large quantities, as far as possible to use expansion type centering method, to eliminate the gap, to reduce the gear jump has a certain role.
4, workpiece or tool loading card positioning is not good, no longer the correct position theory.Think of these, hope you useful points.
3, the tool scene is larger, or the center of rotation of the tool axis and geometric center error is larger.
The main reason for the radial runout tolerance of gear ring is that:1, the material uniformity is poor.2, the machine tool workpiece spindle rotation accuracy is low.
