The maintenance method decision of hard tooth surface reducer

Regarding the maintenance countermeasures for speed reduction machinery and equipment, and based on the details of the N42 hard-tooth surface reducer, it is clear that the common faults of its key components are all over the solid model, maintenance methods and optimal maintenance cycle time.

The actual work is as follows:

1. Starting from the consideration of the key functions of maintenance decision-making in China's processing and manufacturing industry, the development history of reliability maintenance is introduced in detail, and the research status and development trend of reliability maintenance in various countries in the world are analyzed in the field of system software. At this stage, a series of problems that have emerged in the specific application of maintenance decision-making are explained in detail on the theoretical basis, standards, basic problems, core technology and basic implementation process of Reversible AC Gear Motors Company, and establish a theoretical basis for the research on maintenance decision-making of speed reduction machinery and equipment.

2. The common failure modes and hazards of the key components of the N42 worm planetary reducer are analyzed in detail, the lethality of each component is measured, and the failure description fault tree of the N42 hard tooth surface reducer is created. After analyzing the FMECA and FTA of the N42 hardened gear reducer, the reliability entity model and the maintainability entity model of the reducer are built.

3. Consider the maintenance method of the rack and pinion in the N42 hard-tooth surface reducer from the three levels of reliability, maintainability and rationality, and use the entropy method to make detailed calculations to determine the key maintenance method of the rack and pinion. . Subsequently, a group of common fault data information of rack and pinion is obtained arbitrarily, and the research is carried out using mathematical statistics to make it clear that the common faults of rack and pinion are all regular. Then, according to the measurement entity model that measures the protective maintenance cycle time according to the reasonable degree, the maintenance cycle time of the rack and pinion is decided.

4. Developed and designed the planetary reducer maintenance decision-making terminal software. The system software can carry out the basic information management of the reducer, and can clarify the maintenance method of the speed reduction mechanical equipment according to the influence factors selected by the customer, and make decisions based on the maintenance cycle time selected by the customer The solid model calculates the best preventive maintenance cycle time of the speed reduction mechanical parts.
