Technical Field

[0001] The utility model relates to the technical field of transmission devices, in particular to a wear-resistant gear for mechanical transmission. Background Art

[0002] In mechanical transmission systems, gears are core components, and their performance directly affects the operating efficiency and reliability of the equipment. With the continuous expansion of industrial production scale and the advancement of technology, higher requirements are placed on the wear resistance of gears.

[0003] Wear is a major problem facing gears today. In actual operation, friction between tooth surfaces, contact stress, and complex operating conditions lead to widespread gear wear. Wear not only reduces gear precision and transmission efficiency but also causes equipment failure, increasing repair costs and downtime. Specifically, gear wear is particularly severe under high-load, high-speed operating conditions. For example, in equipment such as automotive engines and large industrial machinery, gears must withstand enormous pressure and friction, making them prone to wear, fatigue, and galling. Furthermore, harsh operating environments, such as high temperature, high humidity, and dust, can accelerate gear wear. Furthermore, traditional gear lubrication methods have shortcomings and are unable to meet the lubrication needs of gears under complex operating conditions. Problems such as uneven lubricant distribution and the breakdown of the lubricating film prevent the tooth surfaces from being fully lubricated, further exacerbating wear. Therefore, a wear-resistant gear for mechanical transmission has been proposed to address this problem by improving the lubrication system. Utility Model Content

[0007] Furthermore, both sides of the tooth body have involute tooth shapes.

[0008] Furthermore, the two left and right oil guide grooves on both sides of the tooth body are arc-shaped and symmetrically arranged, and the middle oil guide groove is straight.

[0023] In order to more clearly and completely illustrate the technical solution of the present invention, the present invention will be further described below with reference to the accompanying drawings.

[0024] Please refer to Figure 1 - Figure 4 The present invention proposes a wear-resistant gear for mechanical transmission. When in use, lubricating oil is first added through the first oil supply hole 21, and the gears will mesh with each other and rotate. When the gears mesh with each other, the tooth body 11 of the contact part will compress the oil storage bag 20 and squeeze the lubricating oil in the oil storage bag 20 out of the second oil supply hole 22, so that the lubricating oil is distributed along the oil guide grooves 12 on both sides of the tooth body 11 to the contact parts on both sides of the tooth body 11, thereby lubricating the tooth body 11 and reducing wear. When the tooth body 11 is not in contact with the oil storage bag 20, the lubricating oil will not flow out of the oil storage bag 20, which can save unnecessary waste of lubricating oil, realize dynamic control, and dynamically adjust the lubrication of the gears, while saving lubricating oil and extending the lubrication time.

[0025] The gear includes a gear body 10, which is made of high-strength alloy steel, such as 40Cr, 42CrMo, etc. These materials have high strength, hardness, and toughness, can withstand large loads and friction, and ensure that the gear is not easily deformed during long-term operation.

[0026] A centrally symmetrical tooth body 11 is fixedly mounted on the edge of the gear body 10, and both sides of the tooth body 11 have an involute tooth profile. The involute tooth profile ensures the smoothness and accuracy of the gear transmission. During the meshing process, the relative sliding between the tooth surfaces is relatively uniform, which can effectively reduce wear. Three oil guide grooves 12 are provided on both sides of the tooth body 11. The left and right oil guide grooves 12 are arc-shaped and symmetrically arranged, and the middle oil guide groove 12 is straight. The width and depth of the oil guide grooves 12 are designed according to the flow rate and flow velocity of the lubricating oil to ensure that the lubricating oil can flow smoothly in the oil guide grooves 12. The surface roughness of the oil guide grooves 12 is required to be high to reduce the flow resistance of the lubricating oil.

[0027] The gear body 10 is provided with a conical mounting groove 13 between the two tooth bodies 11. The taper and size of the mounting groove 13 are designed according to the shape and size of the oil storage bag 20 to ensure that the oil storage bag 20 can be tightly installed in the groove. The surface roughness of the mounting groove 13 is required to be high to ensure the sealing between the oil storage bag 20 and the mounting groove 13.

[0028] A detachable elastic oil storage bag 20 is installed in the mounting groove 13, and oil-resistant nitrile rubber is selected. Nitrile rubber has good elasticity, oil resistance and sealing properties, and can withstand a certain amount of pressure and deformation, ensuring that the oil storage bag 20 will not leak during storage and use. The oil storage bag 20 is conical and adapted to the mounting groove 13. Liquid lubricating oil is stored inside the oil storage bag 20, and its capacity is determined according to the lubrication requirements of the gear and the working environment. The wall thickness of the oil storage bag 20 is uniform, ensuring that the lubricating oil can be evenly squeezed out during the compression process. A first oil supply hole 21 is provided in the middle of the upper part of the oil storage bag 20, and three second oil supply holes 22 are provided on both sides of the upper part of the oil storage bag 20. The second oil supply holes 22 are respectively communicated with and matched with the oil guide groove 12.

[0029] Lubricating oil is injected into the oil reservoir 20 through the first oil supply hole 21. This hole is designed in the middle position above the oil reservoir 20, which is convenient for operation and can ensure that the injected lubricating oil enters the oil reservoir 20 smoothly. When the gears start to engage and rotate with each other, the contact points between the tooth bodies 11 will produce an extrusion effect on the oil reservoir 20. Since the tooth bodies 11 are centrally symmetrically distributed, when the gears engage, the contact parts of the tooth bodies 11 will exert pressure on the oil reservoir 20. Under the extrusion of the tooth bodies 11, the oil reservoir 20 produces elastic deformation. This deformation causes the lubricating oil in the oil reservoir 20 to be squeezed out from the second oil supply hole 22. These holes are located on both sides of the upper part of the oil reservoir 20, corresponding to the oil guide groove 12. After the lubricating oil is squeezed out, it flows along the oil guide grooves 12 on both sides of the tooth body 11. The design of the oil guide groove 12 is exquisite. The arc-shaped oil guide grooves 12 on both sides cooperate with the straight oil guide groove 12 in the middle. The arc-shaped oil guide groove 12 can guide the lubricating oil to the key contact parts of the tooth body 11 as the contact trajectory changes when the tooth body 11 is engaged; the straight oil guide groove 12 assists the lubricating oil to be evenly distributed on the surface of the tooth body 11, so that the contact parts on both sides of the tooth body 11 can be fully lubricated. When the tooth body 11 is not in contact with the oil storage bag 20, the oil storage bag 20 will not be squeezed, and the lubricating oil will not flow out from the second oil supply hole 22. This realizes dynamic control, avoids unnecessary waste of lubricating oil in the non-working state, and extends the lubrication time. During the continuous meshing of the gears, as the tooth body 11 continuously squeezes and releases the oil storage bag 20, the lubricating oil is continuously squeezed out from the second oil supply hole 22 and lubricated through the oil guide groove 12. As long as there is lubricating oil in the oil storage bag 20, this process will be circulated to ensure that the gears are always well lubricated during operation.

[0030] The involute tooth profile on both sides of the gear body 11 ensures uniform relative sliding between the tooth surfaces during meshing, reducing friction and wear between the gear bodies 11. Furthermore, the oil guide groove 12 ensures that the lubricant fully covers the contact area of ​​the gear body 11, effectively reducing surface wear and extending the gear's service life. The wear-resistant gear design reduces the risk of wear-related failures, improving equipment reliability and stability. During long-term operation, the gears maintain excellent working condition, reducing maintenance and replacement costs.

[0031] The design of the elastic oil reservoir 20 and the oil supply hole ensures that oil is released only when the reservoir 20 is squeezed during gear meshing, preventing leakage and waste of lubricating oil when not in operation. This dynamic control method significantly improves lubricating oil utilization and reduces lubricating oil consumption. The lubricating oil stored in the reservoir 20 continuously lubricates the gear body 11, ensuring long-term normal operation of the gears without frequent lubricating oil replenishment. Furthermore, dynamic control prevents excessive lubricating oil consumption, thereby extending the lubrication period.

[0032] Good lubrication reduces friction and energy loss between the teeth 11, making gear transmission smoother and improving transmission efficiency. This helps reduce energy consumption and improve overall performance. Good lubrication reduces friction and vibration between the teeth 11, thereby reducing noise generated during gear operation. This helps improve working comfort and minimizes impact on the surrounding environment.

[0033] The design of the oil guide groove 12 allows for efficient distribution of lubricating oil under varying operating conditions, adapting to a variety of complex operating conditions. Whether operating at high speeds, low speeds, or under heavy loads, the gears can achieve excellent lubrication. The removable design of the oil reservoir 20 facilitates inspection, replacement, and replenishment of lubricating oil, simplifying maintenance and reducing costs.

[0034] Of course, the present invention may have many other implementations. Based on this implementation, other implementations obtained by ordinary technicians in this field without any creative work are all within the scope of protection of the present invention.
