Low-speed gears have the most frequent blockage and broken teeth. When the oil supply quality, oil quantity, oil pressure, transmission load, etc. are all normal, the output gear of the reducer has the lowest speed and the largest torque. The force is greatest, the diameter and unit weight of the gear are the largest, and the requirements for blank forging, machining, heat treatment, and installation are also the most difficult. If certain processes such as technology, control, and quality inspection are not strictly controlled, it may cause the gear to fail. A problem occurred during use. After the reducer has a broken tooth, repairing it is difficult, expensive and takes a long time, which has a great impact on the production of the factory.

 Causes of pitting corrosion on reducer tooth surfaces: (1) Induced by defects or excessive harmful residual stress, which may be local fractures caused by inclusions, micro-grinding cracks or improper heat treatment (2) It may be material inclusions, blanks There is a problem with the forging; (3) The quenching and carburizing process is poor, or other reasons cause quality problems in the gear itself. 

Solution: Choose a reducer produced by a regular manufacturer, keep track and record it, and contact the manufacturer for maintenance in a timely manner if such problems occur. In order for the reducer to operate efficiently, it must be guaranteed by advanced technology. Selecting a reasonable solution to specific faults is the prerequisite for the safe and smooth operation of the reducer. A considerable part of the common failures of reducers are caused by human factors and can be avoided. To implement them well, we must: 1. Strengthen the training of technical personnel, enhance their technical level, and ensure accuracy during installation and debugging. sex. 2. Establish a lubrication maintenance system, select qualified lubricating oil, and strictly implement the oil change cycle and oil filling standards, without exceeding or underpaying. 3. Strengthen inspections, enhance responsibility, discover problems in a timely manner and handle maintenance in a timely manner.
