Causes and solutions for broken teeth of ball mill pinion

2024-09-03 in /by

1. Causes of fatigue fracture of ball mill pinion （1）The main reasons for fatigue fracture of ball mill pinion are: （2）The dynamic load of the transmission system is too large; （3）The radius of the tooth root fillet is too small; （4）The surface roughness value of the tooth root is too large; （5）The tooth root is […]

Introduction to typical forging methods and process flow of large steel forgings

2024-08-15 in /by

Large steel forgings generally refer to products with ingot weight ≥150t and single forging weight ≥90t. The representative grades are generally 25Cr2Ni4MoV, 30Cr2Ni4MoV, 40Cr3MoV, 45Cr4NiMoV, 12Cr2Mo1, 12Cr2Mo1V, 20MnNiMo and other grades of forging materials. Large steel forgings are generally used to manufacture the main components of industrial equipment such as power, shipbuilding, metallurgy, and petrochemicals. […]

Why should large gear processing be finely produced?

2024-08-13 in /by

The production of large gears requires special processes to produce products. Are you curious about the specific processes? Here, the gear manufacturer editor will briefly popularize it for everyone: The large gears of the dryer adopt a unique heat treatment technology in casting to improve the hardness of the gear ring, improve the wear resistance […]

How to choose cast or forged gears?

2024-08-03 in /by

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 […]

Gear shaft processing technology analysis – arrangement of heat treatment process

2024-07-26 in /by

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, […]

Thickness determines the size of the gear

2024-07-16 in /by

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 […]
