[0001] This invention relates to the technical field of open gear protection, and particularly to the application of open gear fixing structures in heavy-duty winches. Background Technology

[0002] Open gear winches are prone to momentary overload during operation, and traditionally designed open gear mounting bases generally lack sufficient safety against such momentary overloads. Over prolonged use, this can easily lead to breakage or failure of the main shaft housing or screws. If not addressed promptly, this can cause significant equipment damage and losses. Summary of the Invention

[0003] This invention proposes a novel open gear fixing structure that is simple in structure and highly reliable, solving the aforementioned problems existing in the use of existing technologies.

[0004] The technical solution of this invention is implemented as follows:

[0009] Preferably, the spindle extension section has a spindle protrusion section drill hole, one end of the connecting rod extends into the spindle protrusion section drill hole and extends out to form a connecting section, and the connecting section of the connecting rod is fixedly connected by a locking member.

[0010] Preferably, the spindle sleeve adopts a transverse pressure plate, which is installed between the spindle and the locking element, and the locking element adopts a locking nut.

[0011] Preferably, the connecting rod is made of a high-strength material.

[0012] As shown in the above scheme, the open gear is mounted on the spindle, and spindle seats are located at both ends of the spindle. The spindle extension at the side end of the open gear protrudes beyond the spindle seat and is fastened to the base frame with screws. The spindle sleeve is fitted onto the protruding section of the spindle.

[0021] The following will refer to the appendices in the embodiments of the present invention. Figure 1-6 The technical solutions in the embodiments of the present invention are clearly and completely described herein. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention. Example

[0022] refer to Figures 1 to 6 As shown, this invention discloses a novel open gear fixing structure, including a base frame 1, a winch drum 6, and an open gear 5. The main shaft is fixed during equipment operation, and the open gear is mounted on the main shaft via bearings. The open gear 5 is mounted on the winch drum 6. The base frame 1 has two mounting platforms 2, each with a main shaft seat 3. The winch drum and the open gear are mounted on the base frame 1 via a main shaft 4. Both ends of the main shaft are respectively fitted with the main shaft seat 3. The main shaft extending from the side end of the open gear extends beyond the main shaft seat to form an extension section 41. A fixing component is mounted on the extension section 41. The fixing component includes a main shaft sleeve 7, a connecting rod 8, and a fixing seat 9. One end of the connecting rod 8 is fixedly connected to the main shaft sleeve 7, and the other end is fastened to the fixing seat 9. The fixing seat 9 is mounted on the side of the mounting platform 2 of the base frame. The fixing seat is installed to the base frame by welding or threaded connection.

[0023] To facilitate later disassembly of the spindle sleeve, the mounting base has a slot 91. The connecting rod is inserted into the slot and then secured with a nut. In use, simply unscrew the nut to remove the connecting rod from the slot, allowing for quick disassembly and maintenance.

[0024] The structure of the spindle bushing can vary; this solution lists three examples:

[0025] Implementation method one, refer to Figure 1 and Figure 2 The spindle sleeve 7 is a circular spindle sleeve that is adapted to the extension section of the spindle. The spindle sleeve has a threaded mounting hole 7-1, and the connecting rod is threaded into the threaded mounting hole. This structure is simple and easy to install.

[0026] Implementation Method 2, see reference Figure 4The spindle sleeve is an annular spindle sleeve. The annular spindle sleeve has an upper pressure end area 72 that is adapted to the extension section of the spindle and two mounting extension platforms 71. Both mounting extension platforms have mounting holes. The above-mentioned connecting rods are provided in two corresponding positions and are respectively connected to the mounting holes by nuts. At the same time, the fixing seat 9 is also widened and two matching slots are opened on it. The connecting rods are connected and fixed by upper nuts 10 and lower nuts 11.

[0027] Implementation method three, see reference Figure 5 , Figure 6 The spindle extension section 41 has a spindle protrusion section drill hole 41-1. One end of the connecting rod extends into the spindle protrusion section drill hole and protrudes to form a connecting section 81. The connecting section of the connecting rod is fixedly connected by a locking member 82, which is a locking nut. In this design, the locking nut functions similarly to a spindle pressure sleeve.

[0028] To further enhance stability and prevent loosening, the spindle sleeve uses a transverse pressure plate 7a, which is installed between the spindle and the locking element.

[0029] The above three embodiments are examples of embodiments of the present invention, but are not limited to these three. The overall structural purpose is to strengthen the fixed side of the open gear through the connecting rod assembly and improve the service life of the equipment.

[0030] To improve strength, the connecting rod is made of high-strength materials, such as alloy structural steel and other metal materials.

[0031] Further explanation of this solution: The main shaft protruding section is connected and fixed to the base frame by the main shaft pressure sleeve 7 and the connecting rod, which distributes the instantaneous overload force during the operation of the open gear transmission and prevents the main shaft seat or screws from breaking or failing. At the same time, it stabilizes the overall structure of the drum assembly and reduces the impact of machine vibration and other factors on structural stability.

[0032] It should also be noted that the terms used in this invention, such as "front," "rear," "vertical," "horizontal," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limiting the scope of protection of this invention.

[0033] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
