Description

Technical Field

[0001] The present application relates to the technical field of gear shafts, and in particular to a gear shaft connection structure. Background Art

[0002] Gear shafts are commonly used to mount gears and transmit power. A gear shaft is a cylindrical metal rod with a series of precise gear grooves that are used to hold gears and transmit torque or speed. By connecting gears of different sizes, a gear shaft can convert input motion (such as speed and torque) into the desired output motion. Gear shafts are widely used in various mechanical equipment and transmission systems, such as automobile engines, industrial machinery, and machine tools.

[0003] In the related art, when installing a gear on a gear shaft, there is usually a hole or keyway on the gear to match the flange or key on the gear shaft to ensure correct positioning; then bolts, pins, nuts and other fixings are used to fix the gear on the gear shaft. However, the gear can only be installed at a fixed position on the gear shaft, and the installation position cannot be adjusted according to the actual installation situation.

[0014] By adopting the above technical solution, after the gear is installed in the gear installation groove, the first locking block and the second locking block clamp the gear.

[0015] Optionally, the locking component further includes:

[0016] A locking rack fixedly connected to the gear mounting seat;

[0017] A locking tooth, slidably connected to the side walls of the first locking block and the second locking block; the locking tooth can be engaged with the locking rack;

[0018] A reset spring is installed on the side walls of the first locking block and the second locking block, and is used to achieve reset after the corresponding locking teeth slide.

[0019] Optionally, the first locking block and the second locking block are both slidably connected with a support block, and the locking tooth is coaxially fixedly connected to the corresponding support block; the first locking block and the second locking block are both fixedly connected with a stop block, and the locking tooth is slidably connected to the stop block; the return spring is sleeved on the locking tooth, and one end abuts against the stop block and the other end abuts against the support block.

[0020] Optionally, a connecting tube is fixedly connected to the stop block, and the locking tooth can pass through the connecting tube; one end of the locking tooth passing through the connecting tube is coaxially threadedly connected to a rotating tube, the end face of the rotating tube is fixedly connected to the locking nut, and the locking nut is threadedly connected to the connecting tube.

[0021] By adopting the above technical solution, the meshing stability between the locking tooth and the locking rack is enhanced.

[0023] Limiting rings are respectively fixedly connected to two sides of the gear mounting seat;

[0024] A threaded rod, one end of which is rotatably connected to the limiting ring;

[0025] The sleeve is fixedly connected to the shaft body, and the other end of the adjacent threaded rod is threadedly connected to the sleeve, and the internal threads at both ends of the sleeve are opposite.

[0026] By adopting the above technical solution, adjacent gear mounting seats can support each other, and because the sleeve is fixedly connected to the shaft body, the gear mounting seat cannot move when the threaded rod is not rotated.

[0027] In summary, the present application has at least the following beneficial effects:

[0028] The purpose of setting a gear mounting seat, a locking component and a limiting component, and making the gear mounting seat slide on the shaft body is to first install the gear on the gear mounting seat, then lock the gear by the locking component, adjust the position of the gear by sliding the gear mounting seat, and then limit the sliding of the gear mounting seat by the limiting component, so as to adjust the installation position of the gear.
