People in the foundry industry know that large gears are transmission parts of mechanical equipment and play a key role in the operation of the entire machine. If the large gear (also called the large gear ring) is worn, it needs to be replaced to delay production. In addition, the large gear is a consumable […]
In the entire process of shaft processing, sufficient heat treatment processes should be arranged to ensure the mechanical properties and processing accuracy requirements of the gear shaft and improve the processing performance of the workpiece. Generally, normalizing treatment is arranged first after the shaft blank is forged to eliminate forging internal stress, refine the grains, […]
The machining sequence is arranged according to the principle of base surface first, rough first then fine, main first then secondary. For general parts of gear shaft, after the center hole is prepared, the outer circle is processed first, and then other parts are processed, and it is important to separate rough and fine processing. […]
The main function of the gear is transmission. Why are some gears large and some gears small? Some people may say it is because of the size of the mold, but not all gear moduli are the ratio of pitch to circumference. The larger the modulus, the stronger and thicker the teeth, and the larger […]
Large gear rings are important and indispensable parts of equipment, just like gears. Although the two are similar, their main function is to transmit and change the direction of force. However, in addition to this, the protection of the main body of the machine system by the drive of the gear ring cannot be ignored. […]
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 […]
New progress in the manufacturing and application of large-scale mechanical rollers: Safety production and industry exchanges are equally important. Recently, a series of new progress has been made in the field of large-scale mechanical roller manufacturing, which not only improves production efficiency, but also expands the application field, and also puts forward higher requirements for […]
Recently, a series of new progress has been made in the field of large-scale mechanical roller manufacturing, which not only improves production efficiency, but also expands the application field, and also puts forward higher requirements for safe production. In terms of manufacturing, the application of new materials makes the rollers have higher strength and wear […]
In the past, gears were usually made by casting, but now more and more gears are produced by forging. 1. Forging can provide higher strength and toughness. Gears are subjected to huge pressure and load during operation, so their materials must have sufficient strength and durability. In contrast, gears made by casting usually have internal […]
The large gear ring of the drum dryer plays a very important role in the entire dryer transmission system. The quality of the large gear ring directly affects the operation and life of the dryer. To choose a good quality large gear ring, you need to understand from the following aspects? Material selection and hardness […]
