1、 Case 1: Alpine Ski Resort Cable Car System Environmental conditions: High altitude mountainous areas, winter temperatures can drop below -25 ° C. Problem faced: Gearboxes are prone to malfunction at low temperatures, directly affecting the safety of tourists. Selection and Solution: Special lubrication: Select special low-temperature gear oil to ensure good fluidity even at extremel
1. Loose heat sinks are primarily caused by equipment vibration and fall under the external fastener inspection category, which includes visual inspection and actual fastening checks Visual inspection (shift/day rounds) During inspection, visually check whether the heat sink is tilted or cracked. For operating conditions with significant vibration, gently shake the heat sink to determine if
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
