Description

TECHNICAL FIELD

[0001] The utility model relates to the synchronous belt field especially a kind of synchronous belt with continuous tooth slot. BACKGROUND

[0002] Synchronous belt is a kind of transmission parts with the advantages of chain, gear and triangular rubber belt, which is composed of a ring belt with equidistant tooth shape on inner circumferential surface and a corresponding matching wheel. It plays an important role in transmission equipment and is widely used in mechanical transmission of various types in various industries such as textile, machine tool, tobacco, communication cable, light industry, chemical industry, metallurgy, instrument, food, mine, petroleum and automobile.

[0003] The existing conventional general synchronous belt tooth slot is linear or herringbone tooth type along the width direction of synchronous belt. When linear synchronous belt transmits or drives power, the tooth surface will be partially worn after long-term use, which will cause the destruction of one belt wheel tooth type and the phenomena of tooth shedding, tooth jumping and tooth scratching during the later meshing with synchronous belt wheel, affecting normal use. Similarly, the middle slot needs to be set in the middle of the width direction of herringbone tooth type synchronous belt, which provides a termination position during the process of manufacturing herringbone tooth and makes it more convenient to arrange and cut during processing.

[0004] The above-mentioned conventional general linear synchronous belt wheel is simple to process and has good transmission capacity, but long-term high-efficiency operation will cause the deviation of synchronous belt and synchronous belt wheel, and the synchronous belt wheel with the same tooth type needs to be installed with a stop ring or other structure to make the synchronous belt transmit between the stop ring or other structure, thereby reducing the deviation degree of synchronous belt and synchronous belt wheel. The above-mentioned conventional general herringbone tooth type synchronous belt has good guiding property, but the tooth type needs to be processed left and right respectively and the middle slot needs to be set in the middle direction of synchronous belt width, which increases the processing procedure.
