Two methods of gear grinding and related instructions

The two methods of gear grinding and related instructions are as follows, for reference and understanding.

Two methods of gear grinding:

1. Parallel shaft grinding

The workpiece 1 rotates slowly and reciprocates quickly along the axis.The grinding wheel 2 is driven by 1 wheel to rotate, and does a short feed movement, and changes the direction of rotation after a certain period of time.When grinding teeth,gearPut the abrasive in between.

2. Grinding teeth of cross shaft

The workpiece meshes with the grinding wheels 2, 3, and 4, and the workpiece is the driving wheel, which performs axial reciprocating motion. After a certain period of time, the coup rotates in the direction of rotation.

Description of gear grinding:

1. The grinding wheel is usually cast iron, and the commonly used brand is HT300.The tooth profile of the grinding wheel is similar to that of the workpiece, and its diameter should be as large as possible to increase the number of regrinds and durability.In order to avoid the local wear of the grinding wheel or the periodic error of the grinding wheel tooth profile reflected in the tooth profile of the workpiece, the number of teeth of the grinding wheel cannot be an integral multiple of the number of teeth of the workpiece; the tooth thickness of the grinding wheel should be smaller than that of the standard workpiece, and the gap between the two should be The particle size of the abrasive is determined.

2. Cutting specification, the general cutting speed is 30~60m/min.

3. The precision of grinding is related to the grinding allowance.The normal tooth grinding process has two stages. The first stage is to grind the tooth surface unevenness and other scars and deformations.The second stage is the uniform wear stage.The margin is generally 0.01~0.04mm.
