Description

Technical Field

[0001] The utility model relates to the technical field of mechanical accessories, in particular to a helical gear structure with improved stability. Background Art

[0002] As an important component in mechanical transmission, helical gears are widely used in various industrial equipment and mechanical systems. They transmit torque and rotational motion through the meshing between gears, and have the advantages of high transmission efficiency, strong load-bearing capacity, and smooth operation. The existing helical gear structure still has some technical defects in practical applications. The tooth material and structural design of some traditional helical gears may not meet the requirements of high-intensity working conditions. When faced with high-load power transmission tasks, the teeth may wear too quickly or even suffer fatigue damage on the tooth surface. This is mainly because the material selection is not optimized enough and the tooth structure has not undergone special strengthening treatment. Secondly, the stability is insufficient during operation, which not only affects the transmission efficiency, but also may shorten the service life of the equipment. Utility Model Content

[0027] A helical gear structure that improves stability, such as Figure 1-Figure 3As shown, it includes a helical gear body 10 and a rotating shaft 20 arranged at the center, and bearing seats 30 are installed at both ends of the rotating shaft 20 to improve stability; the helical gear body 10 includes a rotating disk 101 arranged at the center and an alloy steel body 102 arranged on the outside, and a plurality of alloy steel helical teeth 11 uniformly and equidistantly arranged in a ring are installed on the outer wall of the alloy steel body 102, and a connecting sleeve 12 and a fixing sleeve 14 for connecting to the rotating shaft 20 are coaxially arranged at both ends of the rotating disk 101; a plurality of first locking bolts 13 uniformly and equidistantly arranged in a ring are installed on the outer wall of the connecting sleeve 12, and a plurality of second locking bolts 15 uniformly and equidistantly arranged in a ring are installed on the outer wall of the fixing sleeve 14. By installing the bearing seats 30 at both ends of the rotating shaft 20, the stability of the overall helical gear structure can be effectively improved; Through the setting of the helical gear body 10, a connecting sleeve 12 and a fixing sleeve 14 are respectively provided at both ends of the rotating disk 101 at the center thereof, and a number of first locking bolts 13 installed on the outer wall of the connecting sleeve 12 and arranged in a ring at a uniform and equidistant manner, and a number of second locking bolts 15 installed on the outer wall of the fixing sleeve 14 and arranged in a ring at a uniform and equidistant manner can achieve a stable connection between the rotating disk 101 and the rotating shaft 20, thereby ensuring the reliability of the helical gear body 10 during the rotation process; and the alloy steel body 102 outside the helical gear body 10 and the number of alloy steel helical teeth 11 installed on its outer wall and arranged in a ring at a uniform and equidistant manner can not only ensure the strength of the helical gear structure, but also enable it to better complete related functions such as transmission during operation, so that the helical gear structure has good performance in terms of stability, reliability and functionality.

[0028] It is worth noting that the rotating disk 101, the alloy steel body 102 and the alloy steel helical teeth 11 are an integrally formed structure, which makes the overall structure of the helical gear more compact and stronger. The helical angle of the alloy steel helical teeth 11 is 10°-25°, which optimizes the transmission efficiency and load-bearing capacity of the gear.

[0029] Furthermore, the rotating shaft 20 includes a main shaft 21 and a wear-resistant sleeve 22 arranged on the outer wall. The main shaft 21 adopts a carbon steel shaft to ensure the strength and rigidity of the rotating shaft. The thickness of the wear-resistant sleeve 22 is 0.5-2mm, which effectively improves the wear resistance and service life of the rotating shaft 22.

[0030] Specifically, the outer wall of the rotating shaft 20 is provided with first fixing screw holes 23 which are the same in number and corresponding in position as the first locking bolts 13 and are threadedly connected, so that the connecting sleeve 12 can be firmly fixed on the rotating shaft 20, thereby enhancing the connection stability between the helical gear body 10 and the rotating shaft 20.

[0031] In addition, the outer wall of the rotating shaft 20 is provided with second fixing screw holes 24 with the same number, corresponding positions and threaded connection of the second locking bolts 15, so that the fixing sleeve 14 can also be firmly installed on the rotating shaft 20, further improving the stability and reliability of the overall structure.

[0032] Working principle of this helical gear structure with improved stability:

[0033] First, during installation, the rotating shaft 20 is passed through the connecting sleeve 12 on the rotating disk 101 at the center of the helical gear body 10. Then, the rotating shaft 20 and the connecting sleeve 12 are firmly connected using the first locking bolts 13 arranged evenly and equidistantly in a ring shape on the outer wall of the connecting sleeve 12 to ensure a tight fit between the two.

[0034] Next, the fixing sleeve 14 is placed on the rotating shaft 20 at a suitable position and further fixed by a plurality of second locking bolts 15 arranged evenly and equidistantly in a ring shape on the outer wall of the fixing sleeve 14 to ensure that the helical gear body 10 does not experience axial displacement on the rotating shaft 20.

[0035] Afterwards, the two ends of the rotating shaft 20 with the helical gear body 10 installed are respectively installed with bearing seats 30 for improving stability, so that the entire structure can be placed stably and remain stable during subsequent operation;

[0036] During actual use, the shaft 20 is driven to rotate by external power, driving the helical gear body 10 to rotate. At this time, the alloy steel helical teeth 11 on the alloy steel body 102 outside the helical gear body 10 will engage with other transmission components to complete the corresponding power transmission and other tasks.

[0037] The above shows and describes the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are merely preferred examples of the present invention and are not intended to limit the present invention. Various changes and improvements may be made to the present invention without departing from the spirit and scope of the present invention, and such changes and improvements fall within the scope of the present invention.
