What are the causes of errors in powder metallurgy gear machining?
Powder metallurgy gears can be used in all kinds of products. The quality of powder metallurgy gears will affect the quality of applied products. When purchasing powder metallurgy gears, we should pay more attention to the quality of powder metallurgy gears. For powder metallurgy gear manufacturers, the quality should be strictly checked when producing powder metallurgy gears, and unqualified powder metallurgy gears should be abandoned when they should be abandoned, The quality of P/M gears is influenced not only by the choice of manufacturing materials, but also by the use of manufacturing tools and technical means. Today, we will introduce the factors that affect the errors in the processing of powder metallurgy gears.
1. The accuracy of the transmission chain of the machine tool is not high, and vibration or impact occurs during operation, affecting the instability of the machine tool transmission.
2. The contact between the spindle of the worktable and the conical guide surface of the worktable shell is not satisfactory. The conical guide surface is hard to contact, and the worktable rotates heavily. Vibration occurs during operation, causing errors in processing.
3. If the cutter mechanism does not work properly, return the cutter to scrape the workpiece surface.
4. Poor grinding quality of gear shaper cutter.
5. The feed rate is too large, resulting in the untimely cutting of the powder metallurgy gear by the tooth cutter, which results in the rough surface of the powder metallurgy gear.
6. Powder metallurgy gear blanks cannot be installed reliably, and vibration occurs during cutting.
7. The cutting fluid is dirty, or it is flushed into the cutting gear case. The surface quality of P/M gear is not qualified.
These factors may lead to errors in the processing of P/M gears, which will lead to the use effect of finished P/M gears. Qualified P/M gears can be used more smoothly. However, P/M gears with poor quality will always have problems of one kind or another in the use process, and may even cause internal damage to mechanical equipment.
