Embodiment Construction

[0025] 1. Description of single worm overrunning clutch

[0026] 1. Structure description

[0027] As shown in FIG. 1 : the worm gear 2 is assembled in the volute shaft hole 11 a through the worm gear shafts 1 and 8 . The worm gear shaft 8 is fixedly connected with the bevel gear 9 and meshed with the bevel gear 7 with a key. The shaft 12 of the bevel gear 7, the disk 13 is an integral component (according to the needs of the process, it can also be made into discrete components and assembled into a fixed assembly) and is assembled in the volute shaft hole 11c. The gear 5 is concentrically assembled on the disc 13 through the screw 6 and meshed with the gear 3 . The plane of the gear 5 is milled into a waist groove at the fastening hole of the screw 6, which is used for fine-tuning the left or right offset of the meshing of the worm screw and the tooth surface of the worm gear during assembly. The worm 10 is fitted with shafts 4, 14 in the volute shaft hole 11b. The gear 3...

Abstract

The present invention discloses a single-worm surpassing clutch and its stepless speed variator. It is single-worm surpassing clutch type stepless speed variator assembled using the single-worm surpassing clutch. The present invention is novel in structure, and compared with the existent technology, the output power is more stable and possesses the characteristics of long service life, high reliability low cost, etc.

Description

technical field [0001] The invention relates to a single worm overrunning clutch, in particular to a continuously variable transmission composed of an eccentric shaft, a connecting rod, a planetary gear train, a fixed shaft gear train and an overrunning clutch. Background technique [0002] The core components used in the gear meshing drive CVTs disclosed in Chinese Patent No. ZL97202412.2 and Chinese Patent Application No. 98115713.0 are double worm overrunning clutches. [0003] The double worm overrunning clutch has been in development and trial operation in recent years. It proves that it has a substantial breakthrough to the traditional ratchet, pawl type, roller, wedge sleeve type overrunning clutch (also known as mechanical secondary tube through lock device). Played the great value of structural adjustment of old and new products. However, in continuous practice and exploration, we found that the double worm overrunning clutch has many parts and requires high machi...
