This application discloses an electronically controlled moving chainring mechanism, a shifting system, and a bicycle. The bottom bracket is installed in a cylinder body and is fixed circumferentially to the bushing. The piston is detachably connected to the bushing. When the pedal drives the bottom bracket to rotate, the bottom bracket drives the bushing to rotate, which in turn drives the chainring to rotate. When the freewheel shifts gears, the electronically controlled drive mechanism can actively drive the piston to move axially, and drive the bushing and chainring to adjust their positions synchronously, thereby reducing the angle between the chain, chainring, and freewheel, and improving riding efficiency. Furthermore, the reduced angle expands the meshing range between the chain and the teeth, reducing chain slippage, asymmetrical wear, and axial stress, lowering the risk of tooth deformation, and extending the service life of components. Compared to the traditional passive adjustment method of the chain driving the chainring, this embodiment actively controls the chainring movement through an electronically controlled drive mechanism, resulting in smoother and more precise chainring movement, avoiding jamming, and ensuring stable positioning after reaching the correct position, thus improving riding stability.

This utility model relates to the field of welding technology. An embodiment of this utility model provides a welding device for ship steel plates, including a workbench. A base is fixedly connected to the bottom of the workbench, and foot pads are fixedly connected to the bottom of the base. A welding device is mounted on the top of the workbench. In this utility model, the operator places the plate to be welded onto the workbench, thereby starting a dual-output shaft motor. Its two output shafts rotate synchronously, driving two active power gears to rotate. Because the number of teeth on the active power gear is less than the number of teeth on the driven power gear, the driven power gear rotates at a slower speed. This gear ratio design allows the threaded rod to rotate slowly and stably. As the threaded rod rotates, the threaded sleeve gradually moves along the circumference of the threaded rod. This technical solution solves the problem of unstable clamping and welding of plates in related technologies.
