Description

Technical Field

[0001] The utility model relates to the field of high-strength impact-resistant gears, and more specifically, to a novel high-strength impact-resistant gear. Background Art

[0002] Gears are widely used and are important parts in various mechanical equipment, such as machine tools, airplanes, ships, and watches and electric fans used in daily life. There are many types of gears, including cylindrical spur gears, cylindrical helical gears, spiral gears, spur bevel gears, spiral bevel gears, worm gears, etc. Among them, the most commonly used and simplest are cylindrical spur gears, also known as standard cylindrical gears. There are two methods for processing gear tooth profiles. One is the forming method, which is a method of cutting out tooth profiles using a forming milling cutter that is completely consistent with the shape of the gear tooth groove to be cut, such as milling; the other is the development method, which is a processing method that uses the mutual meshing movement of the gear cutter and the passive gear to cut out tooth profiles, such as hobbing and slotting (demonstrated with a hob and slotting cutter). The following introduces the method of processing gears using a milling machine. Gears are mechanical parts with teeth that can mesh with each other. They are extremely widely used in mechanical transmission and the entire mechanical field. Modern gear technology has achieved: gear module 0.004 ~ 100 mm; gear diameter from 1 mm to 150 meters; transmission power can reach hundreds of thousands of kilowatts; speed can reach hundreds of thousands of rpm; the highest circumferential speed is 300 meters per second;

[0003] Gears have vibration and noise problems due to the meshing sound caused by transmission error and the tooth collision sound caused by the backlash. Since gears are used in combination, they need to have higher fatigue strength, high wear resistance, high heat resistance and high impact resistance than existing uses. In addition, they are also required to have high oil resistance, high gasoline resistance and low impact on the gears on the meshing side.

[0004] In the prior art, such as the authorization announcement number CN218118525U in the field of gear technology, specifically a new impact-resistant gear, including a gear body, the inner ring of the gear body is provided with a connecting mechanism, the connecting mechanism is provided with a buffer mechanism inside, the connecting mechanism includes a connecting shaft, and the connecting shaft is fixed to the inner ring of the gear body. The utility model adds a connecting member between the gear and the shaft inside, so that the gear can get a certain buffer when it stops, thereby solving the problem of deformation of the gear due to excessive inertia;

[0005] The gears thereof adopt a separation structure and the internal axial springs are used for buffering. The stability of the mechanism is poor when it is used, the pressure generated by the gears when they are pushed to rotate is large, and the above structure is unstable. Utility Model Content
