Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of gears, in particular to a high-speed anti-twisting error helical gear. Background Art
[0002] Gears are a common part often used in mechanical transmission. Gears are made of high-quality high-strength alloy steel, with surface carburizing and hardening treatment, strong load-bearing capacity and durability. In practical applications, helical gears are widely used in high-speed and heavy-load occasions due to their stable transmission, low impact, vibration and noise. Helical gears are not completely helical gears. It should be said that helical gears are the meshing method of two helical gears, which are distinguished by the different directions of their force transmission in space. Ordinary spur gears mesh at the same time along the tooth width, thus generating impact vibration noise and unstable transmission.
[0003] Helical gears are usually installed in the gear shift transmission parts of automobile transmissions. Since helical gears generate a lot of heat when they rotate at high speed or shift gears, the heat dissipation effect of lubricating oil alone is poor, which will cause the helical gears to overheat and shorten their service life. At the same time, it will affect the meshing accuracy of the helical gears and cause abnormal noises over time. In response to the above problems, a solution is proposed below. Utility Model Content
[0004] The utility model aims to provide a high-speed anti-twisting error helical gear, which has the advantages of good heat dissipation effect, high meshing precision and prevention of abnormal noise.
[0005] The above technical objectives of the utility model are achieved through the following technical solutions:
[0006] A high-speed anti-twisting error helical gear comprises a helical gear body, a connecting column is provided on one side of the helical gear body, a shift gear is connected to the other end of the connecting column, a heat dissipation groove is provided on one side of the helical gear, a plurality of spoilers are fixedly provided in the heat dissipation groove, each of the spoilers is arranged at an angle, a plurality of flow holes are opened on the other side of the helical gear body, a mounting hole is opened on one side of the helical gear body, and the other end of the mounting hole extends into the connecting column and the shift gear, a plurality of the flow holes are all connected to the heat dissipation groove, and the outer surfaces of the helical gear body, the connecting column and the shift gear are coated with a reinforcing coating.
[0007] Preferably, a groove is provided on the surface of the connecting column, a plurality of lubrication holes are provided in the groove, and the other ends of the plurality of lubrication holes are connected to the mounting hole.
[0008] Preferably, the strengthening coating is a manganese phosphating coating.
[0009] Preferably, the helical gear body is arranged by a chamfering process.
[0010] Preferably, both ends of the mounting hole are rounded.
[0011] The beneficial effects of the utility model are:
[0012] 1. When the helical gear rotates for a long time or performs gear shifting, it will generate more heat. Therefore, when the helical gear rotates, it can drive several spoilers to rotate. Since several spoilers are arranged at an angle, the fluidity of the lubricating oil on the helical gear can be accelerated. The fluidity of the lubricating oil and the rotation of several spoiler blades can effectively dissipate the heat generated when the helical gear is working, thereby preventing the helical gear from overheating, so the service life of the helical gear can be effectively improved. The fluidity of the lubricating oil on the helical gear can be further improved through several flow holes, so that the lubricating oil can better contact with the helical gear, so that the helical gear can be more lubricated, so as to ensure the meshing firmness and meshing accuracy of the helical gear, and can effectively prevent the helical gear from overheating, so it can effectively prevent the helical gear from producing abnormal noise.
[0013] 2. The grooves can help the lubricating oil to penetrate better, and a number of lubrication holes can increase the fluidity of the lubricating oil, so that the lubricant can enter the mounting hole better, thereby reducing the friction between the helical gear and the shaft after installation, so the service life of the helical gear can be further improved, and the generation of abnormal noise can be effectively prevented.

[0019] like Figures 1 to 3 As shown, a high-speed anti-twisting error helical gear includes a helical gear body 1, a connecting column 2 is provided on one side of the helical gear body 1, a shift gear 3 is connected to the other end of the connecting column 2, a mounting hole 7 is opened on one side of the helical gear body 1, and the other end of the mounting hole 7 extends into the connecting column 2 and the shift gear 3. The mounting hole 7 can be used to facilitate the installation of the helical gear on the shaft of the transmission component, so that the helical gear can shift and slide, and at the same time can rotate around the shaft.
[0020] A heat dissipation groove 4 is provided on one side of the helical gear, and a plurality of spoiler blades 5 are fixedly arranged in the heat dissipation groove 4, and each spoiler blade 5 is inclined. A plurality of flow holes 6 are opened on the other side of the helical gear body 1, and the plurality of flow holes 6 are all connected with the heat dissipation groove 4. When the helical gear rotates for a long time or performs gear shifting, it will generate more heat. Therefore, when the helical gear rotates, the plurality of spoiler blades 5 can be driven to rotate. Moreover, since the plurality of spoiler blades 5 are inclined, the fluidity of the lubricating oil on the helical gear can be accelerated. Moreover, the fluidity of the lubricating oil and the rotation of the plurality of spoiler blades can effectively dissipate the heat generated when the helical gear works, thereby preventing the helical gear from overheating. Therefore, the service life of the helical gear can be effectively improved. Moreover, the fluidity of the lubricating oil on the helical gear can be further improved through the plurality of flow holes 6, so that the lubricating oil can be in better contact with the helical gear, thereby ensuring that the helical gear is more lubricated, so as to ensure the meshing firmness and meshing accuracy of the helical gear, and effectively prevent the helical gear from overheating and heating, thereby effectively preventing the helical gear from generating abnormal noise.
[0021] A groove 8 is provided on the surface of the connecting column 2, and a plurality of lubrication holes 9 are provided in the groove 8. The other ends of the plurality of lubrication holes 9 are connected with the mounting hole 7. The groove 8 can help the lubricating oil to penetrate better, and the plurality of lubrication holes 9 can increase the fluidity of the lubricating oil, so that the lubricant can better enter the mounting hole 7, thereby reducing the friction between the helical gear and the shaft body after installation, so that the service life of the helical gear can be further improved, and the generation of abnormal noise can be effectively prevented.
[0022] The outer surfaces of the helical gear body 1, the connecting column 2 and the shift gear 3 are all coated with a reinforcing coating, which is a manganese phosphating coating. By applying the manganese phosphating coating, the helical gear as a whole can have good corrosion protection and salt spray resistance, and at the same time has better oil resistance, solvent resistance, acid and alkali resistance, and better resistance to stamping, impact, scratch and wear, thereby greatly improving the service life of the helical gear.
[0023] The helical gear body 1 is chamfered, which can effectively reduce the wear between the helical gear and other gear components and make the meshing of the helical gear and other gear components more precise. Both ends of the mounting hole 7 are rounded, which can effectively prevent the helical gear from scratching the shaft.
[0024] 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 protection scope of the present invention.
