Detachable type triangular belt wheel with adjustable diameter

Abstract

The invention relates to a triangular belt wheel, in particular to a detachable type triangular belt wheel with an adjustable diameter. The detachable type triangular belt wheel comprises a shaft sleeve and a plurality of sector belt type grooves. Circular shaft sleeve end plates are fixed to the two ends of the shaft sleeve. Circular through grooves are evenly formed in the shaft sleeve end plates. The two ends of each belt type groove are connected with sector fixing plates. Two rows of arc protrusions are arranged at the positions, corresponding to the circular through grooves, of the fixing plates. The distance between the two rows of arc protrusions is equal to the distance between every two adjacent circular through grooves. The two rows of arc protrusions are embedded in the two corresponding adjacent circular through grooves. The shaft sleeve end plates at the two ends of the shaft sleeve and the sector fixing plates are fixed through studs and cover-shaped nuts. The detachable type triangular belt wheel is simple in structure and convenient to use, the diameter size of the triangular belt wheel can be adjusted at will, the belt type grooves and bearings are conveniently detached, the production cost is low, and the labor intensity is lowered.

Description

technical field [0001] The invention relates to a V-belt pulley, in particular to a detachable V-belt pulley with adjustable diameter. Background technique [0002] At present, the commonly used V-belt pulleys are all cast and formed, and the belt-shaped grooves of the V-belt pulleys are obtained by mechanical cutting. In this way, the leftovers after cutting account for about half of the weight of the original V-belt pulleys, not only Raw materials are wasted, and the labor intensity of operators is increased. An interference fit is used between the belt-shaped groove and the shaft sleeve. Once fixed, it cannot be disassembled. After the belt-shaped groove is worn out, it is not convenient to replace it, which increases production costs. In addition, in different usage occasions, there will be different requirements for the diameter of the V-belt pulley. The existing V-belt pulley has a fixed diameter and cannot be adjusted in size.

Problems solved by technology

[0002] At present, the commonly used V-belt pulleys are all cast and formed, and the belt-shaped grooves of the V-belt pulleys are obtained by mechanical cutting. In this way, the leftovers after cutting account for about half of the weight of the original V-belt pulleys, not only A waste of raw materials also increases the labor intensity of the operator. The interference fit between the belt-shaped groove and the shaft sleeve cannot be disassembled once it is fixed. After the belt-shaped groove is worn out, it is not easy to replace it, which increases production costs.

In addition, in different usage occasions, there will be different requirements for the diameter of the V-belt pulley. The diameter of the existing V-belt pulley is fixed, and the size cannot be adjusted.
