ベルト。[Claims for Utility Model Registration] Consisting of an endless tension band and a large number of blocks having a fitting part for fitting the tension band and sliding contact parts on the left and right sides to slide on the groove surface of the pulley. On the upper and lower surfaces of the tension band, the same number of grooves as the blocks are formed at equal intervals in the length direction and correspond to the upper and lower sides, while the above-mentioned grooves are formed on the upper and lower surfaces of the fitting part of each block. A protrusion is formed that can fit into the groove of the tension band, and the block is locked and fixed to the tension body in the longitudinal direction of the belt by engagement of the groove of the tension band and the protrusion of each block. This is a V-belt for high-load transmission, and a concave portion having an inner circumferential surface with an arcuate cross section is formed on one side in the direction of belt movement at the left and right centers of the center pillars of each of the above blocks, while on the other side ,
A convex portion is formed which has an outer circumferential surface having an arcuate cross-section and can be fitted into the concave portion of the adjacent blocks, and the inner circumference of the concave portion has its center on the pitch line of the belt and extends between the blocks. The outer periphery of the convex part is made up of two upper and lower arcuate surfaces with different radii of curvature, with the pitch line as the boundary, and the upper half is located on the pitch line. It is an arcuate surface having a center and a radius of curvature smaller than the recess, while the lower half is curved from the pitch line to prevent the lower half from coming into contact with the recess when the belt is bent in the normal direction to the minimum radius. V for high load transmission, characterized in that the V has a center located on the upper side of the concave portion, and is an arcuate surface having a radius of curvature greater than the radius of curvature of the recessed portion.
belt.
