Embodiment

[0025] Example: see Figure 1 to Figure 4 , a capstan two-way overrunning clutch 100, including a fixed outer ring 1, a first star wheel 2, a second star wheel 3, a third star wheel 4 and a number of rollers 5, wherein the first star wheel 2, the second star wheel The wheel 3 and the third star wheel 4 are coaxially arranged in the outer ring 1 in sequence. The first star wheel 2 and the third star wheel 4 have the same structure and are symmetrically distributed on both sides of the second star wheel 3. The outer ring 1 and the third star wheel A number of rollers 5 are evenly arranged in the circumferential direction, and a plurality of concave grooves 20, 30 are arranged on the side of each star wheel to form the inner raceway of the corresponding roller. A group of concave grooves 20, 30 corresponding to the three star wheels share One roller 5, the center of the first star wheel and the third star wheel has a hexagonal hole, the second star wheel 3 is connected to the pow...

Abstract

The invention discloses a winch two-way overrunning clutch which comprises an outer ring, a first star wheel, a second star wheel, a third star wheel and a plurality of rolling columns. The first star wheel, the second star wheel and the third star wheel are coaxially arranged inside the outer ring. The rolling columns are evenly distributed in the peripheral direction among the outer ring and the three star wheels. A plurality of concave grooves are formed in the peripheral side face of each star wheel to form inner roller paths corresponding to the rolling columns. The three star wheels and the concave grooves matched with the star wheels correspondingly share the same rolling columns. Hexagonal holes are formed in the centers of the first star wheel and the third star wheel. The second star wheel can rotate relative to the first star wheel and the third star wheel by an alpha angle so as to achieve the exceeding or self-locking state. The invention further provides a winch. Due to the adoption of the clutch, the transmission torque is large, the efficiency is high, braking is reliable, no heat is emitted, and the service life is long.

Description

technical field [0001] The invention discloses a winch two-way overrunning clutch and the winch, which belong to the technical field of clutches according to the International Patent Classification (IPC), and in particular relate to the clutch technology applied to the winch. Background technique [0002] The overrunning clutch is an important part used for the power transmission and separation function between the prime mover and the working machine or between the driving shaft and the driven shaft inside the machine. functional device. Overrunning clutches can be divided into one-way overrunning clutches and two-way overrunning clutches: the existing two-way overrunning clutches with shift forks are difficult to release when overrunning, have large wear and poor reliability, and require heat treatment and roller wedge groove processing in the manufacturing process. Also difficult. [0003] Chinese document CN103075440A discloses a roller type two-way overrunning clutch, ...
