Embodiment Construction

[0008] The present invention will be specifically described below in conjunction with the accompanying drawings.

[0009] According to the number of V-belts required in the transmission, an appropriate number of transmission discs (3) are installed on the outer circle of the transmission shaft sleeve (1), and the keys (4) are used for circumferential positioning between them. Lock nuts (2) are respectively screwed on both sides of the sleeve, and the distance h between the trapezoidal grooves is adjusted so that the V-belt forms a suitable envelope radius on the pulley. In order to prevent the V-belt between the two pulleys from deflecting, the two pulleys must use the same structure.

Abstract

The invention relates to a novel v-belt pulley structure, according to the number of v-belts which are needed in the transmission, transmission plates (3) with proper quantity are arranged on the outer circle of a transmission shaft sleeve (1), the transmission plates (3) are located circumferentially by keys (4), locking screw nuts (2) are respectively screwed on two sides of the transmission shaft sleeve, the distance h between ladder-shaped grooves is adjusted to form a suitable enveloping radius on the belt pulley of the v-belt. In order to avoid the deflection of the v-belt between two belt pulleys, the belt pulleys need to be in the same structure. The novel v-belt pulley structure has the beneficial effects that the change of the transmission can be conveniently realized, thereby being suitable to the requirement of a transmission system which needs to change the transmission frequently.

Description

technical field [0001] The invention relates to a V-belt pulley, in particular to a novel V-belt pulley structure. It belongs to the technical field of electromechanical equipment. Background technique [0002] The V-belt pulley is an important part of the rotating system of mechanical equipment. It is known that the V-belt pulleys are all fixed structures. This kind of pulley cannot realize the purpose of conversion and transmission in some places where conversion and rotation are required. Contents of the invention [0003] The object of the present invention is to provide a new type of V-belt pulley structure, this kind of pulley can achieve the purpose of speed change only after making corresponding adjustments in places where speed change is required. [0004] The technical solution adopted to solve the technical problem is: install a number of rotating discs whose electric cross-sections are opposite isosceles trapezoids, and install them on the rotating shaft sleev...
