Description
Technical Field
[0001] This utility model relates to the field of gear technology, specifically to a gear with a tooth wear-resistant structure. Background Technology
[0002] Gears are mechanical components with teeth on their rims that can continuously mesh to transmit motion and power. Gears have been used in transmission for a long time. In the late 19th century, the principle of generating gear cutting and the emergence of special machine tools and cutting tools for gear cutting based on this principle were developed. With the development of production, the smoothness of gear operation has become important. The better the wear resistance of a gear, the longer its service life. Generally speaking, the higher the hardness of the gear, the higher its wear resistance. However, excessive hardness may also lead to cracking and breakage of the tooth surface.
[0003] In existing gear processing, gears are generally carburized to greatly increase the carbon concentration on the gear surface and improve its hardness. Quenching, on the other hand, changes the crystallization state of the gear through rapid cooling, which can also improve its hardness.
[0004] The friction of gears is concentrated at their meshing points, i.e., their tooth surfaces, while the remaining parts are largely unaffected by friction. Especially when the teeth come into contact, the rapid rotation of the gear causes intense friction on this contact surface. This leads to problems such as lubricant depletion and increased surface wear under long-term load operation, resulting in a shorter gear lifespan and requiring regular lubrication and maintenance. To address this, we propose a gear with an anti-wear structure for the teeth. Utility Model Content
[0005] The summary section of this application is intended to provide a brief overview of the concepts, which will be described in detail in the detailed description section below. This summary section is not intended to identify key or essential features of the claimed technical solutions, nor is it intended to limit the scope of the claimed technical solutions.
[0006] The purpose of this invention is to provide a gear with a tooth wear-resistant structure to solve the problems mentioned in the background art.
[0007] To achieve the above objectives, this utility model provides the following technical solution: a gear with a wear-resistant tooth structure, comprising a main body, an oil injection pile fixed at the center of the main body, the main body including a gear body, and a gear ring fixed around the outer wall of the gear body, the two sides of the gear body having concave annular grooves, and the annular grooves having circular holes inside, the outer walls of the gear ring having external teeth fixed around the perimeter, the ends of the external teeth having shaft grooves, and the bottom surface of the inner wall of the shaft grooves having oil drain holes, the two ends of the inner wall of the shaft grooves being axially connected to rollers, the gear body having an oil storage cavity inside the perimeter, and one end of the oil storage cavity being connected to a connecting pipe, the end of the connecting pipe being connected to an oil storage ring, and the outer walls of the oil storage ring having distribution pipes.
[0008] Furthermore, the outer wall of the gear body is fixedly connected to the gear ring around its perimeter, and the outer teeth are evenly distributed around the outer wall of the gear ring.
[0009] Furthermore, the oil storage cavity and the circular hole are arranged in an annular staggered pattern along the inside of the gear body, and the circular hole is opened in a through shape.
[0010] Furthermore, the oil storage chamber is connected to the inside of the oil injection pile, and the oil storage chamber is connected to the oil storage ring through a connecting pipe.
[0011] Furthermore, the oil storage ring is connected to the oil drain hole through a diversion pipe, and the oil drain hole is arranged at equal intervals along the bottom surface of the inner wall of the shaft groove.
[0012] Furthermore, the roller is axially connected to the end of the external tooth, and the diverter is embedded in the center of the external tooth.
[0013] Furthermore, the bottom surface of the roller is close to the surface of the shaft groove, and the oil drain holes are arranged along the bottom surface of the roller in the same horizontal line.
[0014] Furthermore, the oil injection pile includes a central pile, and gear shafts are fixed on both sides of the center of the central pile. A rubber hole is fixed at the center of the end of one set of gear shafts, and an oil injection pipe is opened at the center of the central pile and the gear shaft. Oil injection cavities are distributed around the outer wall of the oil injection pipe, and an oil storage cavity is connected to the end of the oil injection cavity.
[0015] Furthermore, the end of the oil injection pipe is connected to the rubber hole, and the rubber hole is embedded in the end of the gear shaft to form an inner conical opening.
[0016] Furthermore, the oil injection pipe is connected to the oil storage chamber through the oil injection cavity, and the oil injection cavity is evenly distributed around the bottom end of the oil injection pipe.
[0017] Compared with the prior art, the beneficial effects of this utility model are: This gear uses a gear body as its framework, with annular grooves and distributed circular holes inside the gear body. This reduces the overall weight and stress, and decreases the load and blocks vibration propagation during long-term operation, thereby reducing the wear caused by the gear's own vibration. At the same time, the oil reservoirs distributed inside the gear body are all connected to the oil reservoir ring. When the gear is running, the centrifugal force generated by the rotation allows the oil reservoirs to continuously supply oil to the oil reservoir ring. This, together with the distribution pipe of the external gear, continuously and slowly discharges lubricating oil, thus maintaining the continuous lubrication of the gear and avoiding the drawback of periodically adding lubricating oil. In conjunction with the rollers, rolling friction is formed during the meshing process, which further reduces the wear on the tooth groove surface caused by insufficient lubrication and cornering. This gear has a centrally fixed stake, which can be assembled and used through the gear shafts at both ends of the central stake. Then, oil can be easily injected through the rubber hole at the center of the gear shaft end. The rubber hole has a conical opening structure, which can easily inject lubricating oil while preventing oil leakage. Together with the surrounding oil injection chambers, the oil storage chamber is evenly injected to maintain a long-term internal lubricating oil supply. Attached Figure Description

[0023] This disclosure will now be described in detail with reference to the accompanying drawings and embodiments.
[0024] This utility model provides, for example Figure 1-4 The gear shown includes a gear body 1 with an oil injection pile 2 fixed at the center of the gear body 1. The gear body 1 includes a gear body 101, and a gear ring 102 is fixed around the outer wall of the gear body 101. The two sides of the gear body 101 are provided with concave annular grooves 103, and the annular grooves 103 are provided with circular holes 104. External teeth 105 are fixed around the outer wall of the gear ring 102. The ends of the external teeth 105 are provided with shaft grooves 106, and the bottom surface of the inner wall of the shaft groove 106 is provided with oil drain holes 107. Rollers 108 are axially connected to both ends of the inner wall of the shaft groove 106. An oil storage cavity 109 is provided around the inside of the gear body 101, and a connecting pipe 110 is connected to one end of the oil storage cavity 109. An oil storage ring 111 is connected to the end of the connecting pipe 110, and a diversion pipe 112 is distributed around the outer wall of the oil storage ring 111. like Figure 1-3 As shown, this gear can be structured using a gear body 101. Inside the gear body 101, there is a ring groove 103 and distributed circular holes 104 through-structure, which can reduce the overall weight and reduce stress effects. During long-term operation, it reduces the load and blocks vibration propagation, thereby reducing the wear caused by the vibration of the gear itself. At the same time, the oil storage chambers 109 distributed inside the gear body 101 are all connected to the oil storage ring 111. When the gear is running, the centrifugal force generated by the rotation can make the oil storage chambers 109 continuously supply oil to the oil storage ring 111. This, together with the diversion pipe 112 of the external gear 105, continuously and slowly discharges lubricating oil, thereby maintaining the continuous lubrication of the gear and avoiding the disadvantage of periodically adding lubricating oil. Together with the roller 108, it forms rolling friction during the meshing process, thereby further reducing the wear phenomenon on the tooth groove surface caused by insufficient lubrication and cornering. The oil drain holes 107 are arranged in the same horizontal line along the bottom surface of the roller 108, so that when the oil drain holes 107 are drained with the distributor pipe 112, they are more evenly attached to the surface of the roller 108, thereby achieving a highly efficient and uniform lubrication effect.
[0025] like Figure 2-4 As shown, the oil injection pile 2 includes a central pile 201, and gear shafts 202 are fixed on both sides of the center of the central pile 201. A rubber hole 203 is fixed at the center of the end of one set of gear shafts 202. An oil injection pipe 204 is opened at the center of the central pile 201 and the gear shafts 202. Oil injection chambers 205 are distributed around the outer wall of the oil injection pipe 204, and the end of the oil injection chamber 205 is connected to an oil storage chamber 109. The aforementioned gear has a central post 201 fixed at its center. It can be assembled and used through the gear shafts 202 at both ends of the central post 201. Then, oil can be easily injected through the rubber hole 203 at the center of the end of the gear shaft 202. The rubber hole 203 has a conical opening structure, which can easily inject lubricating oil while preventing oil leakage. In conjunction with the surrounding oil injection chambers 205, the oil storage chamber 109 is evenly injected with oil to maintain a long-term internal lubricating oil supply.
[0026] In summary, when using this gear, the user first inserts a high-pressure injector or other oiling device into the rubber hole 203 and injects the oil into the oiling pipe 204 from the angle of the rubber hole 203. Then, the oil is discharged into the oil storage chamber 109 through the oiling chambers 205 around the oiling pipe 204. After the oiling is completed, the gear can be put into use. When the gear is in a rotating state after meshing, the centrifugal force generated by its rotation will continuously and slowly discharge the lubricating oil from the oil storage chamber 109 into the oil storage ring 111 through the connecting pipe 110. With the continuous centrifugal force, the lubricating oil flows evenly to the surrounding distribution pipes 112 along with the oil storage ring 111 until it flows to the oil drain hole 107 at the end. It is then evenly discharged along with the oil drain hole 107 and adheres to the surface of the roller 108. The roller 108 rotates with the meshing of the entire gear, forming lubrication of the entire tooth groove and meshing area, and can be lubricated synchronously with the meshing parts.
