Description

Technical Field

[0001] This utility model relates to the field of glass production technology, and in particular to a manually disengaged one-to-three gearbox for a glass production line. Background Technology

[0002] In float glass and rolled glass production lines, the annealing furnace drive system typically employs a "one-to-three" structure, where a main motor drives three roller conveyors simultaneously via a gearbox. To facilitate equipment maintenance, troubleshooting, or parts replacement, the gearbox requires a disengagement mechanism to separate the motor from the load. Existing gearbox disengagement mechanisms are usually located on the side of the large gear with high torque and inertia. However, disengagement requires overcoming enormous torque and inertia, resulting in extremely high operating torque. This often necessitates specialized tools or even multiple personnel, making the operation very difficult. Furthermore, the massive energy release during disengagement generates a strong mechanical impact, easily leading to gear breakage, bearing damage, and other malfunctions. The entire disengagement and resetting process is time-consuming, increasing equipment downtime, reducing maintenance efficiency, and impacting overall production efficiency. Therefore, we propose a manually disengaged one-to-three gearbox for glass production lines. Utility Model Content

[0014] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings and examples. The following examples are only used to more clearly illustrate the technical solution of this utility model and should not be construed as limiting the scope of protection of this utility model.

[0015] like Figure 1-5As shown, this utility model is a manually detachable one-to-three gearbox for a glass production line, including a housing 1. An input shaft 2 is inserted into the upper end of the housing 1. Multiple equidistant first bearings 3 are located at one end of the input shaft 2 inside the housing 1. A first gear 4 is fixedly installed on the outside of the first bearings 3. A movable sleeve 5 is located on one side of the input shaft 2 near the first gear 4. The movable sleeve 5 is movably connected to the input shaft 2 and can reciprocate horizontally on the input shaft 2. The housing 1 is located near the first gear 4. An output shaft 6 is inserted below, with both ends of the output shaft 6 movably connected to the housing 1. A second gear 7, meshing with the first gear 4, is provided on the output shaft 6. A shaft 8 is located inside the housing 1 on one side above the second gear 7, with both ends of the shaft 8 movably connected to the housing 1. Sleeves 9 are provided at both ends of the shaft 8 inside the housing 1. A connecting rod 10 is fixedly connected to the upper part of each sleeve 9. The upper end of the connecting rod 10 is fixedly connected to a limiting block 11. A limiting ring groove 12, matching the limiting block 11, is provided on the movable sleeve 5. The cross-section of groove 12 is larger than that of limiting block 11. Sleeve 9 is fixedly connected to shaft 8. When shaft 8 rotates, the connecting rod 10 can drive limiting rod 11 to rotate through the transmission of sleeve 9. When connecting block 11 rotates, the connecting block 11 can push movable sleeve 5 to reciprocate horizontally through the transmission of connecting block 11. Guide blocks 13 are provided on both sides of movable sleeve 5. The input shaft 2 is provided with guide grooves 14 that match guide blocks 13. Guide blocks 13 can slide inside guide grooves 14. The cooperation between block 13 and guide groove 14 effectively improves the movement stability of movable sleeve 5. The first gear 4 is provided with four matrix-arranged positioning blocks 15 on the side near movable sleeve 5. The movable sleeve 5 is provided with positioning grooves 16 that match the positioning blocks 15. When the movable sleeve 5 moves, the positioning blocks 15 are inserted into the positioning grooves 16. Through the cooperation between the positioning blocks 15 and the positioning grooves 16, when the input shaft 4 rotates, the first gear 4 also rotates through the transmission of the movable sleeve 5.

[0016] The input shaft 2 is movably connected to the housing 1 via a second bearing 17. The second bearing 17 can reduce the friction between the input shaft 2 and the housing 1, improve the rotational stability of the input shaft 2, and reduce wear.

[0017] Bearing seats 18 are provided on both sides of the upper end of the housing 1. The input shaft 2 is inserted into the middle of the bearing seat 18. The bearing seat 18 plays a role in fixing and supporting the second bearing 17, further improving the stability of the installation of the input shaft 2 and preventing the input shaft 2 from shifting during high-speed rotation.

[0018] One end of the input shaft 2 passes through the housing 1 and is fixedly connected to the connecting flange 19. The connecting flange 19 facilitates the connection of the input shaft 2 to an external power source, and the connection is firm and easy to disassemble.

[0019] One end of the shaft 8 passes through the housing 1 and is fixedly connected to the push rod 20. The lower end of the push rod 20 is inserted with a limit bolt 21. The housing 1 has threaded holes 22 on both sides of the lower end of the push rod 20. By pushing the push rod 20, the shaft 8 can be rotated, which in turn drives the limit block 11 to move through the sleeve 9 and the connecting rod 10, thereby realizing the axial movement of the movable sleeve 5. When the movable sleeve 5 moves to the designated position for engagement or disengagement, the limit bolt 21 is screwed into the corresponding threaded hole 22 to limit and fix the push rod 20, ensuring the stability of the movable sleeve 5.

[0020] The housing 1 is provided with a mounting plate 23 at the bottom. The mounting plate 23 has a plurality of mounting holes 24 arranged in a matrix. The gearbox can be fixedly installed at a designated position on the glass production line through the mounting plate 23 and the mounting holes 24. The installation is firm and the installation position is easy to adjust.

[0021] Specifically, in this utility model, when three output shafts 6 need to operate simultaneously, the push rod 20 drives the shaft 8 to rotate. The shaft 8, through the sleeve 9 and connecting rod 10, drives the limiting block 11 to move, thereby pushing the movable sleeve 5 to move along the guide groove 14 of the input shaft 2 towards the first gear 4, so that the positioning block 15 on the first gear 4 is inserted into the positioning groove 16 of the movable sleeve 5. At this time, the movable sleeve 5 rotates synchronously with the first gear 4. The external power source drives the input shaft 2 to rotate through the connecting flange 19. The input shaft 2 drives the movable sleeve 5 to rotate through the guide block 13 and guide groove 14. The movable sleeve 5 drives the first gear 4 to rotate through the positioning block 15 and positioning groove 16. Gear 4 meshes with gear 7, thereby driving the three output shafts 6 to operate synchronously. When it is necessary to pause the operation of a certain output shaft 6, the limit bolt 21 is unscrewed, pushing the push rod 20 in the opposite direction to rotate the shaft 8. This, in turn, moves the limit block 11 through the sleeve 9 and connecting rod 10, pulling the movable sleeve 5 along the guide groove 14 away from the first gear 4, causing the positioning block 15 to disengage from the positioning groove 16. At this time, the movable sleeve 5 separates from the first gear 4, and the first gear 4 loses power and cannot rotate. The corresponding output shaft 6 stops operating. Then, the limit bolt 21 is screwed into the corresponding threaded hole 22 to fix the position of the push rod 20, ensuring that the movable sleeve 5 remains stable in the disengaged state. Through the above operation, the manual disengagement and engagement of a single output shaft 6 can be achieved, adapting to different production conditions.

[0022] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
