COMPENSATION DEVICE FOR RATCHET WHEEL WITH BEVEL TEETH

摘要

A compensation device for a ratchet wheel with bevel teeth is provided. Two rows of bevel teeth symmetrical to each other are made on the outer circumference of a large wheel (12) of a ratchet wheel body (1) of the compensation device. The bevel teeth are made up of circumferential teeth (24) and lateral teeth (25). The circumferential teeth (24) are located at two sides of the circumference surface of the large wheel (12), and the lateral teeth (25) are located on the sidewall of the large wheel (12). A U-shaped stop opening (26) is formed on the front end of a stop board (5). The width of the stop opening (26) is the same as the spacing between the bottoms of two lateral teeth. The ratchet teeth of the present invention adopts the bevel teeth structure formed by the circumferential teeth plus the lateral teeth, thus improving stop capability for compensation load and safety operation performance for brake, and enabling the use of a higher working tension and a larger compensation distance. Other aspects of the overall performance of the ratchet wheel compensation device are also improved.
