Description

Technical Field

[0001] The utility model relates to the technical field of mechanical design, and specifically relates to a split sun gear mechanism for overload protection. Background Technique

[0002] The split sun gear mechanism is a device for overload protection, mainly composed of components such as an input shaft, an output shaft, a sun gear, planet gears, a planet carrier, and a fixed external gear ring. Its working principle is similar to that of planetary gear transmission. Through the meshing and cooperation between the sun gear, planet gears, and fixed external gear ring, the transmission between the input shaft and the output shaft is realized;

[0003] When the existing device is in use, when the teeth or splines of the sun gear are damaged after overload failure, the broken teeth may break into the shafting and damage the planet gears, bearings, etc., and even break into the box body, seriously damaging the entire gearbox. At the same time, the construction period for replacing the sun gear is relatively long, and more materials and processes are required. The traditional device usually uses bolts to splice and fix the device, but in actual use, the bolts are prone to loosen under a vibrating environment, resulting in problems such as loosening and malfunction of the device. Therefore, a split sun gear mechanism for overload protection is needed to improve the above problems. Content of the Utility Model

A plurality of bolts 5 are threadedly connected between the sun gear gear section 1 and the sun gear spline section 2, and the sun gear gear section 1 and the sun gear spline section 2 are clamped with each other;

[0025] The limiting component 4 includes a connecting ring 401 and a plurality of connecting plates 402. A plurality of grooves 404 are evenly formed on the side wall of the connecting ring 401. A plurality of springs 406 are respectively fixedly installed on the side walls of the plurality of grooves 404.

[0027] In this embodiment, refer to Figure 1 , Figure 2 and Figure 3 As shown, a receiving groove 6 is formed at one end of the bolt 5, and a plug-in block 409 is clamped in the receiving groove 6;

[0028] The receiving groove 6 and the inserting hole 409 are engaged with each other to restrict the rotation of the bolt 5 provided with the receiving groove 6 .

[0029] In this embodiment, refer to Figure 1 and Figure 2 As shown, a clamping block 405 is slidably installed in the inner cavity of the plug hole 403, and the side wall of the connecting plate 402 is in contact with the inner wall of the connecting ring 401;

[0030] The clamping block 405 and the plugging block 403 are clamped with each other to limit the positions of the connecting plate 402 and the plugging hole 409 .

[0031] In this embodiment, refer to Figure 1 and Figure 2 As shown, the connecting ring 401 is fixedly mounted on the middle of the side wall of the sun gear spline segment 2, and the sun gear segment 1, the sun gear spline segment 2 and the horizontal upward are located on the same axis;
