For spiral bevel gear design, there is indeed a series of specific steps, we must have a clear and accurate understanding of these steps, so that we can avoid major problems in the subsequent design.
7. Advance Calculation and Parameter Determination
first of all, it is necessary to calculate in advance, and determine the gear module, the diameter of the index circle and the width of the gear. These parameters play a key role in the performance and installation of bevel gears. The gear modulus determines the size and carrying capacity of the gear, the indexing circle diameter affects the gear transmission ratio and meshing characteristics, and the gear width is closely related to the strength and stability of the gear. Through accurate calculation and reasonable determination, it can lay a solid foundation for the subsequent design work.
8. determination of geometric parameters and dimensions
next, the geometric parameters and dimensions of the gear are determined, including gear displacement parameters. Gear geometry parameters such as the number of teeth, pressure angle, helix angle, etc. directly affect the gear transmission performance and meshing quality. The determination of the displacement parameters can be optimized according to the specific design requirements and conditions of use, the strength and coincidence of the gear. Accurate determination of these parameters can ensure smooth and efficient operation of the gear during transmission.
9. check calculation
then, according to the tooth surface contact fatigue strength check formula to check the calculation of gear. If necessary, the tooth surface should also be anti-gluing capacity calculation. Tooth surface contact fatigue strength check is to ensure that the gear in the working process, the tooth surface will not be subjected to excessive contact stress and fatigue damage. The tooth surface anti-gluing ability calculation is aimed at high speed, heavy load and other special working conditions, to prevent the occurrence of gear tooth surface gluing phenomenon. Through these checking calculations, we can further verify the rationality and reliability of the gear design.
10. determine the lubrication method
finally, according to the design structure of bevel gear, the lubrication mode of gear transmission is determined, so as to select a suitable lubrication mode. Good lubrication can reduce the friction and wear between gears, reduce transmission noise, and increase the service life of gears. Different design structures and working conditions require different lubrication methods, such as oil lubrication, grease lubrication, etc. Choosing the appropriate lubrication method according to the specific situation can effectively protect the gear and improve the performance of the transmission system.
Through these steps, we are spiral bevel gear at the time of design, a better design effect can be obtained to ensure that spiral bevel gear in practical application, it can run stably and efficiently.
