When manufacturing gears, several typical errors such as eccentricity, pitch error, base pitch error and tooth profile error are usually generated. There are many reasons for gear manufacturers to generate these errors, including errors from machine tool movement, cutting tool errors, errors from improper installation and debugging of tools, workpieces, and machine tool systems, fixture […]
1. Forging and blanking Hot die forging is still the most widely used blank forging process for automotive gear parts. In recent years, wedge cross rolling technology has been widely promoted in shaft processing. This technology is particularly suitable for blanking for relatively complex step shafts. It not only has high precision and small subsequent […]
Recently, Luoyang Hengchang Heavy Machinery Co.,Ltd. cooperated with a company in the wind turbine industry to develop and manufacture a full set of main gear shaft and gear ring. The R&D personnel adopted advanced design concepts to integrate the gearbox main shaft and main shaft bearing into the interior. Under the premise of ensuring the […]
Rotary kiln large gear ring processing manufacturers can produce various large gear rings according to drawings, and can ensure the product quality of large gear rings. So how should the large gear ring be adjusted during use? 1. The construction process of the rotary kiln large gear ring is as follows: divide the circle between […]
How to choose the positioning datum for the processing technology of gear shaft? The processing order of the main surface of the gear shaft depends to a large extent on the selection of the positioning datum. The structural characteristics of shaft parts and the position accuracy requirements of the main surface of the spindle determine […]
Recently, many customers have asked how to choose the material suitable for the large spindle shaft, and how to choose the hard spindle material suitable for their products. Today, Hengchang Heavy machinery will introduce to you how to choose the material. The hardness of the large spindle shaft is a relatively important parameter. Whether the hardness […]
The big gear ring is one of the important transmission parts in mining machinery rotary kiln, ball mill, dryer and other equipment. Its quality is directly related to the continuous stability time and service time of rotary kiln, ball mill and other equipment, so the quality requirements for big gear ring products will be relatively […]
Gears are an important part of mechanical transmission and there are many types of them. Among them, non-standard gear customization has gradually become the mainstream of the market. However, if we accidentally choose unqualified products during the purchase process, it will bring great troubles to our work and life. In order to help everyone avoid […]
