The use of displacement processing can effectively avoid root cutting. When the gear is machined by the Fan method, the tooth tip of the cutting tool cuts off a part of the root of the gear of the machined gear. The undercut gear not only weakens the bending strength of the gear teeth, but also reduces the overlap coefficient. The CQ magnetic transmission pump may reduce the smoothness of the transmission and avoid the stress.
The reason for this is because the height of the tip line of the tool exceeds the meshing limit point. When machining standard gears, the centerline (index line) of the tool should be tangent to the indexing circle of the wheel blank. When the indexing circle modulus and pressure angle of the machined standard gear are determined, the position of the tooth top line and the meshing line of the IH stainless steel chemical pump rack-shaped tool is also determined. Therefore, whether the tip line of the tool exceeds the meshing limit point N1 will depend on the base circle size of the gear being machined. In the case of modulus determination, it depends on the number of teeth of the gear being machined.
In order to avoid undercutting, the tool must be positively displaced; when the calculated minimum displacement coefficient of the undercut is negative, it means that even if the machining tool makes a negative displacement, the undercut will not occur, if it is invariant or positive There will be no undercutting in the displacement.
