Abstract
The invention discloses a large pulley comprising a central shaft and a gear. The central shaft is a polished shaft having one end grooved. The gear is composed of a wheel, a central hole, gear teeth, a fastening threaded hole, a projection, two large hollows and a small hollow, wherein the wheel is provided with the central hole, the gear teeth, the fastening threaded hole, the projection, the large hollows, and the small hollow. The gear teeth are evenly distributed on the outer periphery of the wheel. The central hole is a through hole in the center of the wheel. The fastening threaded hole is formed in the projection. The projection is connected with the central hole. The edge of the lower portion of the fastening threaded hole is connected with the edge of the upper portion of the central hole. The large hollows are arranged on two sides of the projection. The small hollow is arranged below the central hole and between the bottoms of the two large hollows. The grooved end of the central shaft is in interference fit with the gear through the central hole. Therefore, the large pulley is light in weight, convenient to process, fine in operational stability, high in overall strength, convenient to demount, and suitable for applications in gear-belt drive systems.
