Embodiment 1

[0021] A ring gear rotation limiting mechanism includes a driving gear, a rotating flange, a fixed flange, an intermediate idler, and a ring gear; the driving gear and the intermediate idler are installed on the fixed flange, and the driving gear drives the ring gear to rotate through the intermediate idler. The ring gear is mounted on the rotating flange and driven to rotate by the ring gear.

[0022] The fixed flange has outriggers, which are installed and fixed through the outriggers, and the outriggers are evenly distributed on the periphery of the flange; the rotating flange has annular fan-shaped grooves; the legs of the fixed flange pass through the annular fan-shaped grooves of the rotating flange. The ring gear is an incomplete internal gear, the number of teeth depends on the rotation angle allowed by the rotation of the rotating flange. The length of the circular fan-shaped groove arc of the rotating flange depends on the allowable rotation angle of the rotating fla...

Abstract

The invention relates to a gear ring rotation limiting mechanism and belongs to the technical field of mechanical engineering. The gear ring rotation limiting mechanism comprises a driving gear, a rotary flange, a fixed flange, a middle idler wheel and a gear ring. The driving gear and the middle idler wheel are installed on the fixed flange which is fixed; the driving gear drives the gear ring to rotate via the middle idler wheel; the gear ring is installed in the rotary flange which is driven to rotate by the gear ring. The gear ring rotation limiting mechanism is scientific in design, convenient to use, safe and reliable and can be widely applied to rotation limiting devices with a driving shaft and a driven shaft installed coaxially.

Description

technical field [0001] The invention belongs to the technical field of mechanical engineering, in particular to a ring gear rotation limiting mechanism. Background technique [0002] The transmission mechanism with the coaxial installation of the main and driven shafts usually adopts a planetary gear carrier mechanism or an internal gear. At present, the coaxial transmission mechanism of the main and driven shafts is widely used in robot joints. The rotation angle of the joint rotation axis of the robot usually has a certain range. [0003] At present, on the joints of the robot, this kind of coaxial transmission mechanism with rotation angle limit is generally realized by position control commands. In this way, the control program of the drive system is complicated. If there is no mechanical limit, the control program will fail, which will cause the joint to rotate out of control. If the mechanical limit is added, the overload of the system needs to be realized through t...
