DETAILED DESCRIPTION

[0020] The following describes the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. It is obvious that the embodiments described are only some of the embodiments of the present invention, rather than all of the embodiments. Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely represents selected embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative work are within the scope of protection of the present invention.

[0021] like Figure 1 、 Figure 2 As shown, the present invention provides a quick-release gearbox structure comprising a housing 1, a driving gear 2, a driven gear 3, and a driven shaft system 4. The top of the housing 1 is open and provided with a cover 11. The cover 11 is made of a transparent material and is detachably connected to the housing 1 via screws. A sealing strip 15 is provided between the cover 11 and the housing 1. The driving gear 2 and the driven gear 3 are both mounted on the inner bottom of the housing 1. The driven shaft system 4 includes a rotating shaft 41, a bearing seat 42, a gear 43, and a shaft seal 44. A mounting opening 12 is provided on the right side wall of the housing 1. The bottom of the mounting opening 12 is an arc-shaped structure that matches the rotating shaft 41. One end of the rotating shaft 41 passes through the mounting opening 12. A bearing seat 42 is provided at the end and the middle. Gears 43 are provided on the rotating shaft 41 and on the right side of the two bearing seats 42. The two gears 43 are respectively meshed with the driving gear 2 and the driven gear 3. A shaft seal 44 is provided at the other end of the rotating shaft 41. The shaft seal 44 is located on the outside of the housing 1. A sealing assembly is also included. The sealing assembly includes a bottom plate 51 and a side sealing plate 52. The bottom plate 51 is provided on the outside of the housing 1 and close to the mounting opening 12. The side sealing plate 52 is located above the bottom plate 51. A circular mounting space is formed between the bottom of the side sealing plate 52 and the top of the bottom plate 51. The shaft seal 44 is installed in this mounting space.

[0022] In the above structure, both bearing seats 42 are centrally provided with through-holes through which the rotating shaft 41 passes, and the rotating shaft 41 is rotatably connected to these through-holes. The bottom plate 51 is integrally machined with the housing 1. Multiple mounting holes are provided around the mounting opening 12, and the side sealing plate 52 is detachably connected to the housing 1 via screws.

[0023] To further illustrate, the bottom of the housing 1 is provided with two positioning surfaces 13, to which both bearing seats 42 are screwed. Preferably, upwardly protruding stoppers 131 are provided on either side of the positioning surfaces 13, with the bearing seats 42 positioned between the two stoppers 131. Two stopper notches 14 are provided on the inner wall of the housing 1, into which both bearing seats 42 are nestled. The cooperation between the positioning surfaces 13 (including the stoppers 131) and the stopper notches 14 positions the driven shafting in a fixed position within the housing 1, preventing the shafting from drifting left or right or forward or backward during operation.

[0024] The driven shaft conventionally installed in the gearbox needs to pass through the hole in the box body. Due to functional requirements, the driven shaft needs to be connected in series with bearings, gears, shaft seals and other components. If a conventional structure is used, in the process of inserting the shaft into the box body, each bearing, gear, shaft seal and other components need to be inserted into the box body one by one. The box body is small in size and difficult to install. The utility model provides a quick-release gearbox structure, which vertically installs the driven shaft system into the box body from the top as an integral component, and then installs the side sealing plate and the box cover in sequence. Therefore, the parts on the shaft are easy to assemble, and the sealing effect of the box body will not be affected. The specific installation steps are as follows:

[0025] First, assemble the bearing seat, gear, shaft seal, and rotating shaft into a whole, place it vertically into the box, and then use screws to secure the bearing seat to achieve the positioning and installation of the driven shaft system. Then install the side sealing plate, adjust the gear position, and install the box cover to complete the installation of the entire gearbox. Compared with general shaft system installation, it saves a lot of time. During maintenance, only the box cover and side sealing plates need to be removed, and the screws of the bearing seat can be loosened to easily remove the entire shaft system. Then, replace the bearing, gear, or shaft seal; then reinstall it according to the original positioning surface, which has good reinstallability. When replacing, the box does not need to be dismantled as a whole, which is convenient and saves a lot of manpower and material resources.

[0026] The above description is only a preferred embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent structural transformation made using the contents of the description and drawings of the present invention, or directly or indirectly applied in other related technical fields, is also included in the patent protection scope of the present invention.
