Ways to improve the life of drum gear couplings:
The tooth width coefficient affects the tooth root bending strength and tooth surface contact strength of the tooth. The larger the tooth width coefficient, the greater the strength of these two items. The tooth width coefficient affects the coincidence degree. When the tooth width coefficient is less than a certain value, its value The increase of φ has a greater impact on the increase of the coincidence degree, and when the value is greater than this certain value, the increase of the device value has a smaller impact on the increase of the coincidence degree. For the drum-shaped gear coupling with a circular bulge curve, the tooth width is still Determine the parameters of the drum radius and backlash. The larger the tooth width, the larger the drum radius and the larger the required backlash. Therefore, the following two requirements are required: The drum type of the drum gear coupling The tooth surface improves the contact conditions of the inner and outer teeth, avoids the disadvantages of the edge extrusion of the straight tooth tooth under the condition of angular displacement, and the stress concentration. At the same time, it improves the friction and wear of the tooth surface, reduces the noise, and reduces the maintenance cycle. long.The tooth end of the outer gear sleeve is in the shape of a horn, which makes the assembly and disassembly of the inner and outer gears very convenient.
