Description

Technical Field

[0001] The utility model relates to the field of gears, in particular to a wear-resistant insert gear. Background Art

[0002] Wear-resistant insert gear is a specially designed gear. It improves the wear resistance and service life of the gear by embedding wear-resistant materials in the wear-prone parts such as the tooth surface or tooth root of the gear. This technology is widely used in various industrial fields, especially in gear transmission systems under heavy load, high speed and harsh working environment.

[0003] The existing wear-resistant insert gears usually only have a simple gear body, resulting in relatively low overall performance and durability. After long-term use, the gear tooth surface will gradually become thinner due to wear, resulting in increased gear clearance and reduced transmission accuracy, which ultimately affects transmission efficiency and service life. Therefore, those skilled in the art provide a wear-resistant insert gear to solve the problems raised in the above background technology. Utility Model Content

[0004] The purpose of the utility model is to solve the shortcomings existing in the prior art, and a wear-resistant insert gear is proposed. The structure adopts a combination of an external gear and an internal gear, and a protective layer and a shield are sleeved on the outer side walls of the internal and external gears. A connecting groove and a wear-resistant structure and an insert structure are arranged at the inner center. This multi-level and multi-component design helps to improve the overall performance and durability of the gear. Through the bearing shell and the roller, the sliding friction is converted into rolling friction when the gear is running, which significantly reduces the friction force, reduces energy loss, improves the transmission efficiency, reduces internal wear, extends the service life, and reduces the maintenance cost. The rubber layer and the wear-resistant layer are composed of a rubber layer, and the rubber layer plays a buffering and shock absorbing role, absorbs vibration and impact during operation, and reduces stress and wear; the wear-resistant layer is made of cemented carbide, has high hardness and good wear resistance, directly bears friction and wear, and effectively resists external cutting and grinding.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a wear-resistant insert gear, comprising an external gear, the outer wall of the external gear is provided with a plurality of external gear rings in a transverse arrangement, a groove is provided at the center of the upper end surface of the external gear, an internal gear is provided at the center of the upper end surface of the groove, the outer walls of the internal gear and the external gear are both covered with a protective layer, the outer walls of the two protective layers are both covered with a protective layer, the outer wall of the protective layer at the upper part is provided with a plurality of internal gear rings in an annular arrangement, a connecting groove is provided at the inner center of the external gear and the internal gear, a wear-resistant structure is provided on the inner wall of the connecting groove, and an insert structure is provided at the inner center of the wear-resistant structure;

[0006] The wear-resistant structure comprises a rubber layer and a wear-resistant layer, wherein the rubber layer is sleeved on the inner side wall of the internal gear, and the wear-resistant layer is sleeved on the inner side wall of the rubber layer;

[0007] The insert structure comprises a bearing shell and a plurality of rollers. The bearing shell is arranged at the upper center of the wear-resistant structure, and the rollers are arranged in a ring shape on the inner side wall of the bearing shell.

Through the bearing shell and roller, the sliding friction is converted into rolling friction when the gears are running, which significantly reduces friction, reduces energy loss, improves transmission efficiency, reduces internal wear, extends service life, and reduces maintenance costs. The rubber layer and the wear-resistant layer are composed of a rubber layer, and the rubber layer plays a buffering and shock-absorbing role, absorbs vibrations and impacts during operation, and reduces stress and wear; the wear-resistant layer is made of cemented carbide, has high hardness and good wear resistance, directly bears friction and wear, and effectively resists external cutting and grinding.

[0009] Furthermore, the wear-resistant layer is made of hard alloy;

[0010] Through the above technical solution, the cemented carbide has high hardness and good wear resistance. During the operation of the gear, the wear-resistant layer directly bears friction and wear. Due to its high hardness, it can resist external cutting and grinding and reduce the loss of surface material.

[0011] Furthermore, the two protective layers are made of plating materials;

[0012] Through the above technical solution, the coating material usually has good chemical stability and corrosion resistance, and covers the surface of the outer gear and the inner gear to form a protective layer, preventing external corrosive substances from directly contacting the outer gear and the inner gear, and slowing down the process of oxidation and corrosion.

[0013] Furthermore, the two protective layers are made of polymer coatings;

[0027] The multiple outer gear rings 2 on the outer wall of the outer gear 1 mesh with the teeth of other gears to achieve power transmission and conversion. The inner gear 4 works in conjunction with the matching components. The protective layer 6 set on the outer walls of the outer gear 1 and the inner gear 4 can prevent the outer gear 1 and the inner gear 4 from being directly eroded and damaged by the outside world. The protective layer 7 further enhances the protection performance and reduces the influence of external factors such as impact, wear, corrosion, etc. on the outer gear 1 and the inner gear 4. The inner gear ring 8 is used to cooperate with the corresponding components to achieve a specific transmission function. The wear-resistant structure 5 in the connecting groove 10 bears the main friction and wear when the outer gear 1 and the inner gear 4 are running, reducing damage to the internal structure. The wear-resistant structure 5 at the center inside The insert structure 9 helps to improve the stability and wear resistance of the structure. The two protective layers 6 are made of plating materials. The plating materials usually have good chemical stability and corrosion resistance. They cover the surfaces of the outer gear 1 and the inner gear 4 to form a protective layer 6 to prevent external corrosive substances from directly contacting the outer gear 1 and the inner gear 4, thereby slowing down the process of oxidation and corrosion. The two protective layers 7 are made of polymer coatings. The polymer coatings have certain elasticity and toughness. When the outer gear 1 and the inner gear 4 are working, the protective layers 7 can buffer external impacts and collisions and reduce direct damage to the outer gear 1 and the inner gear 4. At the same time, the polymer coating can fill tiny surface defects and pores and provide a certain sealing effect.

[0028] The wear-resistant structure 5 includes a rubber layer 501 and a wear-resistant layer 502. The rubber layer 501 is sleeved on the inner wall of the internal gear 4, and the wear-resistant layer 502 is sleeved on the inner wall of the rubber layer 501. The rubber layer 501 serves as an intermediate layer to provide a buffer and shock absorption effect. It can absorb the vibration and impact generated by the external gear 1 and the internal gear 4 during operation, thereby reducing the stress and wear transmitted to the external gear 1 and the internal gear 4. On the other hand, the wear-resistant layer 502, as the innermost layer, directly contacts the rolling or sliding parts, providing extremely high wear resistance. The wear-resistant layer 502 can effectively resist friction and wear. The wear-resistant layer 502 is made of cemented carbide, which has high hardness and good wear resistance. During the operation of the gear, the wear-resistant layer 502 directly bears friction and wear. Due to its high hardness, it can resist external cutting and grinding and reduce the loss of surface material.

[0029] The insert structure 9 includes a bearing shell 901 and a plurality of rollers 902. The bearing shell 901 is arranged at the upper center of the wear-resistant structure 5. The rollers 902 are arranged in a ring shape on the inner wall of the bearing shell 901. When the gear is running, the rollers 902 can roll freely. When subjected to external force, the rolling of the rollers 902 can convert sliding friction into rolling friction, thereby greatly reducing the friction force. By converting sliding friction into rolling friction, the friction resistance is significantly reduced, the energy loss is reduced, the transmission efficiency is improved, the wear inside the gear is reduced, the service life of the gear is extended, and the maintenance cost is reduced.

[0030] Working principle: Multiple outer gear rings 2 on the outer wall of the outer gear 1 mesh with the teeth of other gears to achieve power transmission and conversion. The internal gear 4 works in conjunction with matching components. The protective layer 6 sleeved on the outer walls of the outer gear 1 and the inner gear 4 can prevent the outer gear 1 and the inner gear 4 from being directly eroded and damaged by the outside world. The protective layer 7 further enhances the protection performance and reduces the influence of external factors such as impact, wear, corrosion, etc. on the outer gear 1 and the inner gear 4. The inner gear ring 8 is used to cooperate with corresponding components to achieve specific transmission functions.

[0031] The rubber layer 501 is used as an intermediate layer to play a role in buffering and shock absorption. It can absorb the vibration and impact generated by the outer gear 1 and the inner gear 4 during operation, thereby reducing the stress and wear transmitted to the outer gear 1 and the inner gear 4. On the other hand, the wear-resistant layer 502, as the innermost layer, directly contacts the rolling or sliding parts, providing extremely high wear resistance. The wear-resistant layer 502 can effectively resist friction and wear. When the gear is running, the roller 902 can roll freely. When subjected to external force, the rolling of the roller 902 can convert sliding friction into rolling friction, thereby greatly reducing friction. By converting sliding friction into rolling friction, the frictional resistance is significantly reduced, the energy loss is reduced, the transmission efficiency is improved, the wear inside the gear is reduced, the service life of the gear is extended, and the maintenance cost is reduced.
