Planetary gearbox is a kind of commonly used reduction equipment, which has the characteristics of small size, large transmission ratio and low noise, and is widely used in various mechanical transmission equipment. What are the factors that affect the bearing of the planetary gearbox?
A planetary gear is a gear system in which, in addition to being able to rotate around its own axis as a fixed shaft gear, its shaft also rotates around the axes of other gears. Due to the complex structure of planetary gears, failures such as fatigue pitting and tooth root cracks are more likely to occur, which will affect the operation accuracy, transmission efficiency and service life of the equipment.
In planetary gear transmission, the load capacity of the planetary gearbox is affected by the size of the ring gear. In the actual design, the bearing capacity of this level is the same, the spatial structure will not change too much, and the general structure is the same. Planetary gearbox bearing life will be affected by factors such as lubrication, degree of contamination, and environmental conditions.
In practical applications, in the case of the same specification and the large difference in the life of the same bearing, we can initially consider revising the minimum bearing life to 3 times, and observe whether the analysis of the results can meet the needs of the project. If it does not meet the requirements, it is necessary to further consider other factors, or even replace the bearing model of the planetary gearbox.
For the gears in the planetary gearbox, the size of the ring gear has a certain relationship with the bearing of the planetary gearbox. Based on the same bearing capacity of the planetary carrier, the service life of the same bearing in different application environments or forms will vary greatly. When the force is the same, the life of the bearing will be inversely proportional to the rotational speed, but in the actual design, the bearing capacity of this stage is the same, and the spatial structure will not change much, generally the same structure. If the bearing life is very different, it will affect the general and borrowing relationship.
In addition to the variables in the basic rating life formula, planetary gearbox bearing life is also affected by other factors, including lubrication, degree of contamination, environmental conditions, etc.
In practical applications, in the case of the same specification and the large difference in the life of the same bearing, we can initially consider revising the minimum bearing life to 3 times, and observe whether the result meets the engineering needs. If it does not meet the requirements, it is necessary to further consider other factors, or even replace the bearing model of the planetary gearbox.
The above are the factors that affect the bearing of the planetary gearbox. In practical applications, the planetary gearbox has different application environments and methods, and the bearing is affected differently under different circumstances.
