Finished internal gear ring
Baohua uses the seamless rolling ring process to provide forged gear manufacturers with shape, size and material flexibility, lower volume requirements and close to the final processing shape to save the final processing cost. Forged gears hand damaged by higher quality and higher strength and wear are formed by grain flow. The mechanical properties and metallurgical stability of the open die forging process are improved. All our forgings can be subjected to hot die forging, rough machining, heat treatment and other processes. Most of the forgings can be finished to meet the final assembly conditions
Customers in any industry using gears and gear rings can request quotations for any number of forged gears and gear rings, from one prototype at a time and small batch to mass production. Our expansion includes gear cutting to finished gear sizes.
The planetary transmission system has the advantages of compact structure, large transmission power, high bearing capacity, strong resistance to shock and vibration, and stable transmission, so it has a very wide range of applications. As one of the important components of the planetary transmission system, the dynamic meshing characteristics of the internal gear ring directly affect the load sharing and dynamic load performance of the transmission system. Analyzing the vibration mechanism of the internal gear ring and proposing the corresponding vibration reduction and noise reduction measures are of great practical significance for designing a planetary gear transmission device with excellent dynamic performance.
Both theoretical analysis and experimental research show that the influence of the flexibility of the internal gear ring on the dynamic characteristics of the system cannot be ignored [1-4]. Increasing the flexibility of the inner gear ring in the planetary gear train will make the load distribution between the planetary gears more uniform.
Hidaka et al. [3] conducted in-depth research on the structure of traditional internal gear ring and obtained the influence of flange thickness on deformation, stress and load sharing coefficient. The results show that the bending deformation of the inner gear ring plays a leading role when the flange thickness is small. With the increase of tooth thickness, the maximum stress on the inner gear ring gradually transfers from the tooth groove to the tooth root, but its load sharing performance is not significantly affected.
Kahraman et al. [5] also established a quasi-static model of the planetary gear train using the finite element method to analyze the influence of the flexibility of the traditional internal gear ring on the gear stress and load distribution.
