    Shenzhen ZHAOWEI Machinery & Electronics Co., Ltd is a professional manufacturer of precision gear reducer. With many years of practical experience, our engineers analyze and share the reasons and solutions of hardened tooth surface gear reducer damage to the customers.

Gear transmission is the most widely used in the application of mechanical transmission, and the plastic gear is a kind of gear product. Because of its low quality, low transmission noise, high temperature resistance and high load capacity, the application of plastic gears is more and more widely used in various fields. In the gear transmission, the gear transmission is accurate, smooth and uniform, especially the high end of the machine.

The important feature of plastic products is the nominal wall, the thickness of the nominal wall will affect the strength, cost and accuracy of parts. And gear products in the process of transmission noise and abnormal sound control is particularly important, the different sound and the gear radial beat, tooth pitch accumulated error has important relationship and with the housing center from size and position tolerances have great southern incense. At the same time, it is important to know that the production of the mold is a decisive factor in the accuracy of the gear, the mold production precision and processing method and processing technology has a vital link.

With the development of science, as well as the light weight requirements of gear products, the gear has been transformed from metal gear into plastic gear, because the plastic gears need better compatibility, durability and wear resistance, as well as the requirements of long life. The plastic gear grease can reduce noise, reduce wear and prolong life. Using synthetic lubricating oil of gear grease, at the same time, the appropriate addition of extreme pressure additives and solid lubricant, not only can improve the bearing capacity of the tooth surface, but also can improve the transmission efficiency, but also can prolong the service life of the gear.

Plastic gear is a kind of plastic structure, its main function is used for the transmission of power and movement. Therefore, the structure of plastic gear must be designed according to the design of the transmission parts and the structure of the plastic structure in two aspects. The gear tooth is an important part of the transmission, is the core of the whole gear, gear design to pay attention to the two aspects, one is the tooth shape correction, two is the balance of tooth thickness.

Tooth shaped dressing: plastic gear using the molding method, the shape of the mold to rely on the shape of the mold cavity to ensure that. At the same time as the cavity by wire cutting processing, so there is no undercutting phenomenon in metal gear machining. But there is no undercut does not mean that the tooth does not produce interference, so to ensure plastic gear has a good meshing tooth profile must be tooth profile correction.
