The primary cause of high temperature in the gearbox is abnormal lubrication, which can be divided into three situations: lack of oil, excessive oil, and poor oil quality. Insufficient lubricating oil leads to heat generation due to dry wear and friction of gears and bearings; If the oil level is too high, the resistance of the oil stirring will increase, generating a large amount of heat; Deterio

Type 1: Sharp screeching sound. Continuous high-pitched screeching during equipment operation is mostly caused by poor gear meshing, severe tooth surface wear, or insufficient lubricating oil. Prolonged operation of a grinding machine with insufficient lubrication leads to dry grinding wear on gear teeth and increased meshing clearance, resulting in screeching. Immediate shutdown is required to in

1、 Preparation before trial operation 1. Disconnect the load from manual turning: Before officially loading, disconnect the output end load and manually rotate the input shaft to confirm that it rotates smoothly and smoothly without any jamming. 2. Check lubrication and connection: Confirm that the specified model and viscosity of lubricating oil have been injected into the box, and that the

1、 Hierarchical loading and running standards Gradual loading: It is strictly prohibited to run directly at full load. It should be loaded step by step at 25%, 50%, 75%, and 100% of the rated load. Run time: Each load stage needs to run continuously for at least 30 minutes, and the next level of loading can only be carried out after all parameters have stabilized. Preheating in high tempe

1. Excessive wear and damage to core components Lack of proper lubrication or cooling can lead to increased friction between key components such as gears, worm gears, and bearings, resulting in excessive wear. For example, low viscosity, failure, or impurities in lubricating oil can make it difficult for the gear tooth surface to form an effective oil film, leading to fatigue pitting and even l

1. Running status monitoring (listening, touching, measuring) Abnormal noise and vibration: Listen to the sound of the gearbox running. If there is high-frequency whistling, dull impact, or periodic abnormal noise, it is usually a signal of gear damage, bearing damage, or improper assembly; Simultaneously feel the vibration of the box with your hands or a vibration meter. Increased vibration of

1. Optimize design and manufacturing processes Material and heat treatment optimization: Select high-strength and high toughness alloy steel materials (such as 20CrMnTi, 42CrMo, etc.). By using heat treatment processes such as carburizing, quenching, and carbonitriding, the tooth surface can achieve high hardness (such as HRC 58-62) to improve wear and compression resistance, while maintaining

1、 Lightweight conveying equipment 1. Lightweight belt conveyor: feeding, sorting and conveying of lighter materials, without significant impact, short distance belt conveyor 2. Roller conveyor line: Light roller conveyor, sorting assembly line roller drive, continuous and smooth operation 3. Small screw conveyor: light powder conveying, non large displacement heavy-duty winch 4. Light
