grinding wheel

Abstract

The invention discloses a grinding wheel, which is used for grinding a belt. The grinding wheel comprises a base part capable of rotating around a rotating axis and a grinding part, wherein the grinding part is used for grinding the belt, and comprises wedge parts which outwards extend along the radial direction of the base part; a grinding material is arranged on the outer surfaces of the wedge parts; each wedge part comprises a trapezoidal main body part and a raised part positioned on the radial outer side of the main body part; each raised part comprises two vertical parts close to the corresponding trapezoidal main body part, two circular arc parts and a horizontal part arranged on the outermost side of the radial direction; the two circular arc parts of each raised part are connected with the corresponding vertical parts and the corresponding horizontal part respectively.

Description

technical field [0001] The invention relates to a grinding wheel, in particular to a grinding wheel for grinding belts. Background technique [0002] The automotive industry or other industrial machinery fields usually drive related equipment through conveyor belts, such as combined V-belts. Grooves are formed between the multiple belts of the combined V-belts, and the grooves usually need to pass through during the manufacturing process. The grinding wheel is ground so as to realize the match between the combined V-belt and the pulley. [0003] U.S. publication No. 5399116 discloses a grinding wheel, which is a cylinder, and its radially outer side is provided with several wedges for grinding belts, the wedges extend in the circumferential direction and are axially spaced, the section of the wedges Roughly triangular in shape, its radially outer terminal ends at a sharp angle. The belt ground by this type of grinding wheel has tooth crests and tooth valleys, and the tooth...

AI Technical Summary

Problems solved by technology

In the process of grinding the belt, this kind of grinding wheel has the following defects: first, in the process of grinding the belt by the grinding wheel, the abrasive material of the first end of the triangular section and the abrasive material of the second end radially outer end surface of the rectangular section are opposite to each other. When the belt is ground, the axial side of the second end will be ground with high-speed sliding friction with the belt because there is no abrasive material for grinding, thereby generating heat, which is likely to cause the rubber crumbs to catch fire, which is an unsafe factor in production, and this The heat may cause the rubber of the belt to melt and stick to the second end of the grinding wheel, thereby affecting the quality of the grinding; secondly, the parts of the first end and the second end that are provided with abrasive materials are likely to produce loss, reducing the service life of the grinding wheel; again, the ends of the wedge-shaped portion are set to multiple shapes, such as two first ends with a triangular cross-section, two second ends with a rectangular cross-section, and the first and second ends Alternately arranged, this structure increases the difficulty of the design and manufacture of the grinding wheel; finally, the belt groove formed by grinding the triangular and rectangular ends of the grinding wheel is rectangular, and its corners are sharp, so the belt has sharp corners during the use of the belt. The groove will easily produce stress concentration, which will cause the belt to break earlier and shorten the life of the belt
