As an ordinary transmission, the main function of gear transmission is to generate power.It has the advantages of fast transmission rate and long service life.In recent years, with the development of industrialization, companies have put forward stricter requirements on gear machining accuracy to ensure the orderly progress of various productions.This article discusses the main factors affecting gear machining accuracy.It is hoped that this research can improve the machining accuracy of gears.

    Factors affecting gear machining accuracy

    There are many factors that affect gear machining accuracy, and the strength and accuracy of each factor are different. From a large amount of experimental data and statistical data, the influencing factors of gear machining accuracy are analyzed in detail, and the main factors affecting gear machining accuracy are analyzed.So as to analyze the main solution to the problem.

    The error of the accuracy of the machine tool itself

    Analyzing the accuracy error of the machine tool from a large amount of data is the main factor that affects the machining accuracy of the gear.The accuracy of the machine tool itself is also related to many factors.The occurrence of this error is caused by the following reasons:

1. There is a radial runout phenomenon in the two middle of the machine,

2. There are different working shafts between the two, and the third working table is divided into errors.

    Error of workpiece and tooling clamping

     The reason for the error is:

1. Generally, there are reference holes and the center axis of the fixture on the processing equipment, which is easy to cause errors;

2. The intermediate shaft of the fixture is sometimes easy to cause radial runout during operation.

3. There is a certain gap between the rotation of the worktable and the mold;

4. When it is used to process gears, the rotation center of the table is completely different from the center of the tire.

Errors caused by the process system itself

1. Radial error: When machining gears, the radial distance between the tool and the gear being machined will be different, which causes the so-called radial error.

2. Tangential error: There are some differences in the indexing between the tool and the gear being cut, which is easy to cause errors.

3. Axial error: In the process of using a cutter to cut gears, the axis of the cutting will sometimes deviate, which will cause errors;

4. Errors of the developing surface: the tool itself will wear out during long-term use, so errors will inevitably occur in the process of machining gears.
