Reasons for peeling, pitting, chipping and broken teeth of reducer gear teeth and treatment methods

For low-speed gears, the phenomenon of block and tooth breakage is the most frequent. When the oil quality, oil volume, oil pressure, transmission load, etc. are normal, the output gear of the reducer has the lowest speed and the highest torque. The force is the largest, the diameter and unit weight of the gear are the largest, and the requirements for rough forging, machining, heat treatment, and installation are also the most difficult. If a certain process such as technology, control, and quality inspection is not strictly checked, it may cause the gear to fail A problem occurred during use.After the gears are broken, the repair is difficult, costly, and has a long cycle, which has a great impact on the production of the factory.

cause:

(1) Defects or excessively high harmful residual stresses may be induced by inclusions, fine grinding cracks or partial fractures caused by improper heat treatment

(2) It may be due to material inclusions and rough forging problems;

(3) The quenching and carburizing process is not good, or other reasons cause the quality of the gear itself.

Approach:

Select the reducer produced by a regular manufacturer, and keep track of records, and contact the manufacturer for maintenance in time for such problems.To make the reducer run efficiently, it is necessary to have advanced technology as a guarantee. For specific failures, choosing a reasonable solution is the prerequisite for the safe and stable operation of the reducer.In the common faults of the reducer, there are a considerable part of human factors, which can be avoided. To implement them well, we must do:

1. Strengthen the training of technical personnel, enhance the technical level, and ensure the accuracy of installation and commissioning.

2. Establish a lubrication maintenance system, select qualified lubricating oil, and strictly implement the oil change interval and oil injection standards, and no excess or shortage.

3. Strengthen inspections, enhance the sense of responsibility, find problems in time and deal with them in a timely manner.

Do not drop foreign objects into the reducer's box.During normal use, the warehouse should purchase gearbox spare parts at a ratio of 5:1. At the same time, prepare a plan for the gearbox that frequently fails. When the reducer fails, it can be replaced in time to ensure that the equipment is in the shortest Normal operation will resume within time.Then disassemble the reducer in the maintenance unit to observe and analyze it in detail to find out the fault situation. For the easily damaged parts such as: seal ring, purchase appropriate spare parts and keep it; for the quality problems of the product itself, contact the manufacturer to identify the replacement or Maintenance; according to the above methods to deal with different failure situations
