Common faults and solutions of Dalian screw gears

Common faults and solutions of Dalian screw gears

Dalian screw gears achieve precise and stable transmission through their unique structural design, but they may also experience malfunctions due to various factors during long-term operation. Understanding common faults and their solutions can help maintain equipment in a timely manner and extend the service life of screw gears.

Wear and tear is one of the more common issues with screw gears. Due to the long-term meshing transmission between the screw and the gear, friction will occur on the contact surface, resulting in tooth surface wear. Especially when there is insufficient lubrication or impurity particles in the working environment, the wear rate will accelerate. To solve such problems, it is first necessary to regularly inspect the lubrication system and promptly replenish or replace suitable lubricating oil; If the wear is severe, the worn parts need to be replaced and the new parts need to be run in to ensure good engagement.

Poor lubrication can also cause a series of problems. Excessive or insufficient viscosity of lubricating oil, oil contamination, and oil circuit blockage can all lead to lubrication failure, resulting in increased temperature, abnormal wear, and even jamming of screw gears. At this time, appropriate lubricating oil should be selected according to the equipment manual, and the oil circuit and filter should be cleaned regularly to ensure that the lubricating oil is clean and flows smoothly; At the same time, establish a regular lubrication maintenance system, monitor the performance indicators of lubricating oil, and promptly identify and address potential issues.

Tooth surface damage such as tooth surface adhesion, pitting, etc. can affect the transmission accuracy and stability of screw gears. This is usually caused by overload operation, poor lubrication, or gear material defects. Once tooth surface damage occurs, different measures should be taken according to the degree of damage: minor damage can be repaired through grinding, polishing, and other methods; When the damage is severe, it is necessary to replace the gears and optimize the operating parameters of the equipment to avoid overload and strengthen lubrication management.

Abnormal transmission is manifested as inaccurate transmission ratio, abnormal noise or excessive vibration during operation. This may be caused by installation errors, gear coaxiality deviation, or loose components. When solving the problem, it is necessary to recalibrate the installation position to ensure that the parallelism and coaxiality of the screw and gear axis meet the requirements; Check and tighten the connecting components to eliminate looseness; If necessary, perform dynamic balancing debugging on the transmission system to restore smooth operation.

Mastering the causes and solutions of common faults in Dalian screw gears can help equipment maintenance personnel quickly diagnose problems, take effective measures, and ensure the reliable operation of mechanical transmission systems.
