Embodiment Construction

[0014] The present invention will be further described below in conjunction with the accompanying drawings.

[0015] Such as figure 1 and figure 2 As shown, a belt pulley includes a pulley body 1, a ring-shaped belt placement groove 2 is provided in the middle of the outer wall of the pulley body 1, the cross section of the belt placement groove 2 is an isosceles trapezoid, and the short side is the belt placement groove 2 Opening, the width of the belt is slightly larger than the width of the short side of the isosceles trapezoid, which is the same as the width of the long side of the isosceles trapezoid. Due to the elasticity of the belt, it can be placed in the belt placement groove 2 by force. This design can prevent the belt from rotating at high speed. In case of falling off, to improve the reliability, the middle part of the mounting surface of the roulette body 1 is provided with a driving bearing mounting hole 3, and the hole wall of the driving bearing mounting hol...

Abstract

The invention discloses a belt wheel disc. The belt wheel disc comprises a wheel disc body, wherein a circle of an annular belt containing groove is formed in the middle part of the outer wall of the wheel disc body; a drive bearing mounting hole is formed in the middle part of the mounting surface of the wheel disc body; a clamping groove is formed in the hole wall of the drive bearing mounting hole; a circle of an annular bump is also arranged on the outer side of the drive bearing mounting hole; a screw thread is formed in the outer wall of the bump; four positioning pins are annularly distributed on the circumference of the bump at equal intervals and are located on the mounting surface of the wheel disc body; lightening holes are formed between adjacent positioning pins; the section of the belt containing groove is a isosceles trapezoid; the short sides are the openings of the belt containing groove. The belt wheel disc is convenient in installation as the positioning pins are arranged, can prevent a belt in high-speed rotation from falling off, reduces the weight of the belt wheel disc as the lightening holes are formed, is convenient in transportation and installation, simple in structure and easy to implement, and achieves good application prospect.

Description

technical field [0001] The invention relates to the technical field of mechanical parts, in particular to a belt pulley. Background technique [0002] Pulleys, which belong to hub parts, are mainly used for long-distance transmission of power, such as small diesel engine power output, agricultural vehicles, tractors, automobiles and other mechanical fields. The existing pulleys are all bolted to the drive mechanism. The assembly is complicated, and the pulley is generally heavy in weight, which is not convenient for installation and transportation. Moreover, the belt placement groove on the pulley is generally a rectangular groove. When running at high speed, the pulley is easy to fall off and needs to be replaced, which affects the transmission effect. Contents of the invention [0003] The technical problem solved by the present invention is to overcome the existing belt pulley, which is complicated to assemble, heavy in weight, inconvenient to install and transport, and...
