Maintenance method of drum gear coupling

Good lubrication is drum tooth typeCoupling*A necessary guarantee for reliable operation is also to slow down wear.Under the conditions of sufficient tooth root bending strength and tooth surface contact strength, the tooth width should be determined with a larger degree of overlap, and the tooth width should not be increased blindly to avoid unnecessary increase in the structural size.The general tooth width factor is 8-14. *The small tooth width should be determined by the allowable root stress, and the width required for the displacement of the force point along the tooth width caused by the inclination between the shafts should also be considered.
     An important way to increase the service 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 it 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 the arc drum curve, the tooth width is still Determine the parameters of the bulge circle radius and the backlash. The larger the tooth width, the larger the bulge circle radius, and the larger the backlash required. Therefore, the following requirements are required: the smaller the concentrated load of a wheel, the better, and The curvature of the tooth surface is proportional to the circumference of the drum, so the radius of the drum is as large as possible.The curvature radius of the bulge curve is proportional to the single-sided thinning of the internal tooth, so the bulge circle radius should be as large as possible.The radius of curvature of the bulge curve is proportional to the single-sided thinning of the internal tooth, that is, it is related to the meshing gap of the tooth. Insufficient thinning may cause interference, and excessive thinning will weaken the strength of the tooth, and the backlash will be large.
