Embodiment Construction

[0007] The specific implementation of the present invention will be described in detail in conjunction with the accompanying drawings and technical solutions. When the ratchet-gear integrated one-way transmission device is used, the gear device is installed on the transmission shaft. The left bush 2 and the right bush 9 are made of anti-friction materials, such as ceramics, polytetrafluoroethylene, etc., which have two functions: one is to reduce the friction and wear when the transmission shaft and the gear 1 move relative to each other; Replacing the bushing can increase the life of the gear unit. A left retaining ring 3 is installed inside the gear 1, and anti-friction material is used to avoid the direct contact between the driving wheel 4 and the gear 1, and reduce the friction and wear of the end face. The right retaining ring 12 installed on the end cover 10 also uses anti-friction material to reduce the friction and wear of the driving wheel 4 and the end cover 10, and...

Abstract

The invention relates to a unidirectional transmission device integrated with a ratchet gear, belonging to a mechanical transmission part, in particular to a unidirectional-transmission overrunning clutching transmission device integrated with a ratchet gear. The outer contour of a gear of the transmission device is provided with gear teeth; an internal cavity of the gear is provided with a ratchet; an internal hole of the gear is provided with a left bush in an interference mode, and the right side of the left bush is provided with a left stop ring; a driving wheel is installed at the internal part of the gear, and the left side of the driving wheel contacts with the right side of the left stop ring; the internal hole of the driving wheel is provided with a key groove, and the driving wheel is connected with a transmission shaft through the key groove and keys; a sunken table is milled on the driving wheel, and a pawl is installed on the driving wheel through a pawl fixing screw; and the sunken table and the pawl of the driving wheel are respectively provided with a pin column, and a spring steel sheet is installed between the pawl fixing screw and the pin column. The invention has compact structure, reliable working and stable performance, can ensure the constant proportion transmission due to the gear structure arranged outside, and can realize convenient overrunning clutching due to the ratchet structure arranged inside.

Description

technical field [0001] The invention belongs to mechanical transmission components, in particular to a one-way transmission overrunning clutch transmission device with integrated ratchet gears. Background technique [0002] At present, the known gear mechanism transmits motion and power between two shafts through the meshing of gear teeth. Compared with other transmission mechanisms, it has the advantages of compact structure, reliable operation, high efficiency, constant ratio transmission and long service life. The involute gears widely used now, as well as arc and parabolic tooth profile gears, etc., can realize bidirectional transmission of motion. However, in some occasions that require one-way transmission motion, a one-way transmission mechanism must be used to achieve the functional requirements, resulting in a relatively bloated transmission mechanism, poor structural compactness, and decreased motion accuracy. noise. Contents of the invention [0003] The tech...
