Description

Technical Field

[0001] The utility model relates to the technical field of gears, in particular to a clutch thin-wall gear. Background Art

[0002] Clutch gears are gear components used for clutch operation and power transmission. Thin-walled gears are a type of clutch gear, characterized by thin walls and long shafts. Existing thin-walled clutch gears generate significant heat over time. Prolonged overheating significantly reduces the gear's service life and prevents lubricant from quickly soaking into the gear, leading to significant wear. To address these issues, the following solution is proposed. Utility Model Content

[0003] The utility model aims to provide a clutch thin-wall gear, which has the advantages of good heat dissipation effect and convenient lubrication and infiltration.

[0004] The above technical objectives of the present invention are achieved through the following technical solutions:

[0005] A clutch thin-walled gear includes a helical gear body, a connecting shaft is provided on one side of the helical gear body, a spur gear is fixed to the other end of the connecting shaft, a mounting hole is provided at one end of the spur gear, and the other end of the mounting hole extends through the connecting shaft and the helical gear body, a plurality of heat dissipation grooves are provided on the surface of the connecting shaft, and the plurality of heat dissipation grooves are all arc-shaped, and each of the heat dissipation grooves is respectively connected to the mounting hole, and a plurality of groups of heat dissipation holes are provided on the spur gear, and the plurality of groups of heat dissipation holes are respectively connected to the mounting holes.

[0006] Preferably, the outer surfaces of the spur gear, the connecting shaft and the helical gear body are all provided with an anti-oxidation coating, and the anti-oxidation coating is a titanium nitride coating.

[0007] Preferably, the outer edge and the inner edge of the positioning protruding ring are both arc-shaped.

[0008] Preferably, two positioning ring grooves are further provided on the inner side of the mounting hole.

[0009] The beneficial effects of the utility model are:

[0010] When thin-walled gears rotate for a long time, meshing friction will generate a lot of heat. At this time, the heat can be dissipated through several heat dissipation grooves. Since the heat dissipation grooves are arc-shaped, when the connecting shaft rotates, the several arc-shaped heat dissipation grooves can rotate at the same time, which can further speed up the efficiency of heat dissipation, thereby greatly improving the service life of the thin-walled gears. The heat generated by the thin-walled gears can also be quickly dissipated through several groups of heat dissipation holes. The circulation of lubricating oil on the spur gears can also be guaranteed through several groups of heat dissipation holes, so that the lubricating oil can quickly infiltrate the inner and outer sides of the thin-walled gears, thereby making the rotation between the thin-walled gears and the clutch shaft components more lubricated, thereby reducing the wear of the thin-walled gears and further improving the service life of the thin-walled gears.

[0014] The following is only a preferred embodiment of the present invention, and the scope of protection is not limited to this embodiment. All technical solutions under the concept of the present invention should fall within the scope of protection of the present invention. The same parts are represented by the same figure marks. It should be noted that the words "front", "rear", "left", "right", "up" and "down" used in the following description refer to the directions in the accompanying drawings, and the words "bottom" and "top", "inside" and "outside" refer to the directions toward or away from the geometric center of a specific component, respectively.

[0015] like Figures 1 to 2 As shown, a clutch thin-walled gear includes a helical gear body 1, a connecting shaft 2 is provided on one side of the helical gear body 1, a spur gear 3 is fixedly provided on the other end of the connecting shaft 2, a mounting hole 4 is opened at one end of the spur gear 3, and the other end of the mounting hole 4 extends through the connecting shaft 2 and the helical gear body 1, and the mounting hole 4 can facilitate the connection between the thin-walled gear and the clutch shaft body, and two positioning ring grooves 8 are also provided on the inner side of the mounting hole 4, and the two positioning ring grooves 8 can make the installation position of the thin-walled gear more accurate.

[0016] The surface of the connecting shaft 2 is provided with a plurality of heat dissipation grooves 5, each of which is arc-shaped. Each heat dissipation groove 5 is respectively connected to the mounting hole 4. The spur gear 3 is provided with a plurality of heat dissipation holes 6, each of which is respectively connected to the mounting hole 4. When the thin-walled gear rotates for a long time and engages with friction, a large amount of heat is generated. At this time, the heat is dissipated through the plurality of heat dissipation grooves 5. Since the plurality of heat dissipation grooves 5 are arc-shaped, when the connecting shaft 2 rotates, the plurality of arc-shaped heat dissipation grooves 5 can rotate simultaneously, further accelerating the efficiency of heat dissipation, thereby greatly improving the service life of the thin-walled gear. The plurality of heat dissipation holes 6 can also quickly dissipate the heat generated by the thin-walled gear. The plurality of heat dissipation holes 6 can also ensure the circulation of lubricating oil on the spur gear 3, so that the lubricating oil can quickly penetrate the inside and outside of the thin-walled gear, thereby making the rotation between the thin-walled gear and the clutch shaft component more lubricated, thereby reducing the wear of the thin-walled gear and further improving the service life of the thin-walled gear.

[0017] The outer surfaces of the spur gear 3, connecting shaft 2, and helical gear body 1 are all coated with an anti-oxidation coating. This titanium nitride coating reduces oxidation on thin-walled gears, significantly extending their service life. A locating collar 7 is fixed to one end of the helical gear body 1. Both its outer and inner edges are curved, effectively preventing scratches between the thin-walled gear and the clutch shaft.

[0018] The specific embodiments described above further illustrate the technical problems, technical solutions and beneficial effects solved by the present invention. It should be understood that the above are only specific embodiments of the present invention and are 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 in the scope of protection of the present invention.
