Description

Technical Field

[0001] The utility model relates to the technical field of mechanical transmission, and specifically relates to a new type of copper worm wheel with high heat dissipation performance. Background Technique

[0002] A worm wheel refers to a gear that can mesh with a worm. As the large gear in an intersecting-axis gear pair, it forms a worm and worm wheel mechanism together with the mating worm, and is often used to transmit the motion and power between two intersecting axes.

[0003] The main functions of the worm wheel include: transmitting motion and power: The worm and worm wheel mechanism can transmit the motion and power between two intersecting axes, which is the basic function of the worm wheel. Through the meshing of the worm wheel and the worm, the motion on one shaft can be transmitted to another shaft, and at the same time, the power transmission is realized. Compact structure: Compared with the intersecting-axis helical gear mechanism, the worm and worm wheel mechanism has a more compact structure. This enables the worm and worm wheel mechanism to achieve efficient transmission in a limited space. Smooth transmission and low noise: The worm drive is equivalent to a screw drive and is a multi-tooth meshing drive. This transmission method makes the worm and worm wheel mechanism have the characteristics of smoothness and low noise during the transmission process. Self-locking property: When the lead angle of the worm is less than the equivalent friction angle between the meshing teeth, the worm and worm wheel mechanism has a self-locking property. This means that in some cases, the worm wheel can only be driven by the worm and cannot be driven by the worm wheel to drive the worm, thus playing a safety protection role.

[0004] However, in actual use of the existing technology, the worm and worm wheel drive is widely used in various mechanical equipment due to its characteristics such as compact structure, large transmission ratio, and stable operation. However, traditional worm wheel materials such as steel and cast iron will generate a large amount of heat due to friction and power loss under long-term high-load operation, resulting in an increase in the temperature of the worm wheel, which in turn affects its mechanical properties and lubrication effect, accelerates wear, and reduces the transmission efficiency and service life. Although copper is an excellent heat-conducting material and has good thermal conductivity, it is limited when directly applied to the manufacture of worm wheels due to insufficient strength and poor wear resistance. Content of the Utility Model

[0005] The purpose of the utility model is to provide a new type of copper worm wheel with high heat dissipation performance to solve the problems raised in the above background technique, that is, traditional worm wheel materials such as steel and cast iron will generate a large amount of heat due to friction and power loss under long-term high-load operation, resulting in an increase in the temperature of the worm wheel, which in turn affects its mechanical properties and lubrication effect, accelerates wear, and reduces the transmission efficiency and service life. Although copper is an excellent heat-conducting material and has good thermal conductivity, it is limited when directly applied to the manufacture of worm wheels due to insufficient strength and poor wear resistance.

[0006] To achieve the above purpose, the utility model provides the following technical solution: It includes a worm wheel main body, and a heat dissipation strengthening layer is sprayed on the outer surface of the worm wheel main body;

[0007] The outer periphery of the worm wheel body is provided with teeth, and ventilation grooves are penetrated through the outer side of the worm wheel body. Mesh support bars for supporting the ventilation grooves are fixedly installed on the inner walls of the ventilation grooves. A transmission shaft hole is penetrated through the middle of the worm wheel body. Adjusting ring grooves are provided on the outer side walls at both ends of the worm wheel body. Conductive square holes are provided on the inner side walls of the adjusting ring grooves. A conductive square column is fitted and movably connected to the inner wall of the conductive square hole. A heat dissipation disc is fixedly installed at the outer end of the conductive square column. Heat dissipation holes are penetrated through the end face of the heat dissipation disc. Vortex heat dissipation fins are fixedly installed on the outer side wall of the heat dissipation disc. An adjusting screw is threadedly connected through the outside of the heat dissipation disc.

[0008] Preferably, the heat dissipation strengthening layer is made of a high thermal conductivity metal material, so as to further improve the heat conduction efficiency of the worm wheel body through the heat dissipation strengthening layer.

[0009] Preferably, there are several teeth, which are symmetrically distributed in sequence around the outer periphery of the worm wheel body. There are several ventilation grooves, which are symmetrically distributed in sequence around the outer side of the worm wheel body. The middle of the ventilation groove penetrates upward to the bottom between the teeth of the teeth.

[0010] Preferably, there are two adjusting ring grooves, which are symmetrically distributed on the outer side walls at both ends of the worm wheel body. There are several conductive square holes, which are symmetrically distributed on the inner side walls of the adjusting ring grooves.

[0011] Preferably, there are several heat dissipation holes, which are symmetrically distributed in sequence at the outer end of the conductive square column. The inner side of the adjusting screw is rotationally connected to the inner side wall of the adjusting ring groove through a rotating shaft.

[0012] Preferably, a fastening nut for locking and fastening the adjusting screw is threadedly connected to the outside of the adjusting screw, and a knob for rotating the adjusting screw is fixedly installed on the outside of the adjusting screw.

[0013] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0014] 1. The present utility model improves the heat conduction efficiency of the worm wheel body through the heat dissipation strengthening layer. The ventilation grooves help the heat generated by the transmission friction of the teeth to be quickly transferred from the bottom between the teeth to the outer end for heat dissipation. At the same time, when the worm wheel body rotates during use, it will synchronously drive the vortex heat dissipation fins to rotate. When the vortex heat dissipation fins rotate, the rotation of the vortex heat dissipation fins can drive the convective movement of the surrounding air, so that the air can more fully contact the surface of the vortex heat dissipation fins, thereby further improving the heat transfer efficiency of the heat dissipation disc and the vortex heat dissipation fins. At the same time, the heat inside the worm wheel body is conducted to the heat dissipation disc through the conductive square holes and the conductive square columns, so as to achieve a high heat dissipation effect of the worm wheel body;

[0015] 2. When the fastening nut for locking and fastening the adjusting screw is loosened in the present utility model, the adjusting screw is rotated through the knob. When the adjusting screw rotates, the heat dissipation disc will move in and out due to the acting force generated by the threaded connection. When the heat dissipation disc moves in and out, it will drive the conduction square column to move linearly in and out along the inner wall of the conduction square hole, so that the heat dissipation disc is limited in linear movement through the cooperation of the conduction square hole and the conduction square column. When the heat dissipation disc moves linearly in and out, it will drive the scroll heat dissipation fins to move linearly in and out for adjustment. Thus, while achieving a high heat dissipation effect of the worm wheel body, it is convenient to adjust the inner and outer extension distances of the scroll heat dissipation fins, so that the worm wheel body can adapt to installation environments of different widths.

At the same time, by adding appropriate alloying elements (such as tin, zinc, nickel, etc.) into the matrix, the hardness and wear resistance of the worm wheel main body 1 are improved. The outer surface of the worm wheel main body 1 is sprayed with a heat dissipation strengthening layer, and the heat dissipation strengthening layer is made of a high thermal conductivity metal material, so as to further improve the heat conduction efficiency of the worm wheel main body 1 through the heat dissipation strengthening layer;

[0023] There are a number of teeth 2 provided on the outer periphery of the worm wheel main body 1, and they are symmetrically distributed in sequence along the outer periphery of the worm wheel main body 1. There are a number of ventilation grooves 3 penetrating through the outer side of the worm wheel main body 1, and they are symmetrically distributed in sequence along the outer side of the worm wheel main body 1. The middle part of the ventilation groove 3 penetrates upward to the bottom of the tooth space of the tooth 2. A grid support bar 4 for supporting the ventilation groove 3 is fixedly installed on the inner wall of the ventilation groove 3. A transmission shaft hole 5 penetrates through the middle of the worm wheel main body 1. There are two adjustment ring grooves 6 provided on the outer side walls at both ends of the worm wheel main body 1, and they are symmetrically distributed on the outer side walls at both ends of the worm wheel main body 1. There are a number of conduction square holes 7 provided on the inner side wall of the adjustment ring groove 6, and they are symmetrically distributed on the inner side wall of the adjustment ring groove 6. A conduction square column 8 is fitted and movably connected to the inner wall of the conduction square hole 7. A heat dissipation disc 9 is fixedly installed at the outer end of the conduction square column 8. A number of heat dissipation holes 10 penetrate through the end face of the heat dissipation disc 9, and they are symmetrically distributed in sequence at the outer end of the conduction square column 8. A scroll heat dissipation fin 11 is fixedly installed on the outer side wall of the heat dissipation disc 9. An adjustment screw 12 is threadedly connected through the outer side of the heat dissipation disc 9, and the inner side of the adjustment screw 12 is rotatably connected to the inner side wall of the adjustment ring groove 6 through a rotating shaft. A fastening nut for locking and fastening the adjustment screw 12 is threadedly connected to the outer side of the adjustment screw 12. A knob for rotating the adjustment screw 12 is fixedly installed on the outer side of the adjustment screw 12.

[0024] Working principle: When in use, the worm wheel body 1 of this utility model adopts a copper alloy with high strength and high wear resistance as the matrix, and at the same time, by adding appropriate alloying elements (such as tin, zinc, nickel, etc.) into the matrix, the hardness and wear resistance of the worm wheel body 1 are improved. The outer surface of the worm wheel body 1 is sprayed with a heat dissipation strengthening layer, and the heat dissipation strengthening layer is made of a high thermal conductivity metal material, so that the heat conduction efficiency of the worm wheel body 1 is improved through the heat dissipation strengthening layer. The ventilation grooves 3 help the heat generated by the transmission friction of the teeth 2 to be quickly transferred from the bottom of the teeth to the outer end for heat dissipation. At the same time, when the worm wheel body 1 rotates during transmission in use, it will synchronously drive the scroll heat dissipation fins 11 to rotate. When the scroll heat dissipation fins 11 rotate, the rotation of the scroll heat dissipation fins 11 can drive the convective movement of the surrounding air, making the air contact the surface of the scroll heat dissipation fins 11 more fully, thereby further improving the heat transfer efficiency of the heat dissipation disc 9 and the scroll heat dissipation fins 11. At the same time, the heat inside the worm wheel body 1 is conducted to the heat dissipation disc 9 through the conduction square holes 7 and the conduction square columns 8, so as to achieve a high heat dissipation effect of the worm wheel body 1;

[0025] At the same time, by rotating the fastening nut that locks and fastens the adjusting screw 12, when the fastening nut that locks and fastens the adjusting screw 12 is loosened, the adjusting screw 12 is rotated by the knob. When the adjusting screw 12 rotates, it will drive the heat dissipation disc 9 to move inward and outward due to the acting force generated by the threaded connection. When the heat dissipation disc 9 moves inward and outward, it will drive the conduction square column 8 to move linearly inward and outward along the inner wall of the conduction square hole 7, so that the heat dissipation disc 9 is limited in linear movement through the cooperation of the conduction square hole 7 and the conduction square column 8. When the heat dissipation disc 9 moves linearly inward and outward, it will drive the scroll heat dissipation fins 11 to move linearly inward and outward for adjustment. Thus, while achieving a high heat dissipation effect of the worm wheel body 1, it is convenient to adjust the inner and outer extension distances of the scroll heat dissipation fins 11, so that the worm wheel body 1 can adapt to installation environments of different widths.
