Drum gear coupling drum curve technical requirements!

What are the technical requirements of the drum profile of the drum profile coupling? The following is a brief explanation of what requirements should be met by the drum profile of a qualified drum profile coupling. Next, learn about the technical requirements of the drum profile of the drum coupling with us.



There are also non-coincidence, the drum curve is mostly an arc, what are the requirements of the drum gear coupling on the drum curve? These circles are called drum circles, and the drum circle focus is on the axis of the gear, and the drum curve is a critical parameter of the drum gear coupling. The general intention is to point mainly, there are not on the axis; With an effective three-segment arc, the dashed line composed of the displacement and axial coordinates is called the drum curve, the center of the drum circle coincides with the spherical center of the tooth surface, and the drum tooth surface of the non-conjugate tooth surface is overlapping by the different end sections, in the arc drum curve, in general, the drum curve of the drum coupling technical requirements are described as follows:

(1) No edge contact occurs when the Angle between axes is at its maximum;

(2) Therefore, the radius of the drum circle should be as large as possible. Therefore, the radius of the drum circle should be slightly larger. The curvature of the tooth surface is proportional to the tympanite PI, and the backlash is large. The thinning amount is too large to weaken the strength of the teeth, the thinning amount is not enough may cause problems, the curvature radius of the drum curve and the internal tooth unilateral thinning amount is proportional, that is, it has nothing to do with the meshing gap of the teeth, the curvature radius of the drum curve and the internal tooth unilateral thinning amount is inversely proportional, the smaller the severance load of the drum gear coupling gear teeth, the better.
