Description

Technical Field

[0001] This application relates to the field of air compressor drives, and in particular to a high-speed gear drive structure. Background Art

[0002] An air compressor, also known as an air compressor, is a device that converts freely flowing air into usable compressed air and is widely used in various industrial and commercial fields. The air compressor increases its pressure by reducing the volume of the gas, thereby providing power. Common working principles include positive displacement and dynamic compression.

[0003] The drive of the air compressor is generally driven by a single drive motor. The output end of the drive motor drives the air compression mechanism in the compressor to work, and then the air compression mechanism sucks and compresses the outside air.

[0004] When the traditional drive motor drives the compressor to work, the output end of the drive motor drives the compressor through a synchronous conveyor belt, and the transmission efficiency is relatively low. Generally, multiple gears are installed at the output end of the drive motor for speed change. Although the transmission efficiency can be improved, multiple sets of gear transmissions are likely to generate a large amount of heat, which may affect the normal operation of the gears in the long run. Utility Model Content

[0005] The purpose of this application is to solve the problem that generally multiple gears are installed at the output end of the drive motor for speed change. Although the transmission efficiency can be improved, multiple sets of gear transmissions are likely to generate a large amount of heat, which may affect the normal operation of the gears in the long run. This application provides a high-speed gear drive structure.

[0006] To achieve the above purpose, this application specifically adopts the following technical solutions:

[0007] A high-speed gear drive structure includes a drive motor. A protective shell is fixed on the drive motor. The output end of the drive motor penetrates through the protective shell and is fixed with a first gear. A second gear is meshed with the first gear. A third gear is fixed on the second gear. The third gear is rotatably connected to the protective shell. A fourth gear is meshed with the third gear. A drive rod is rotatably connected to the protective shell. One end of the drive rod penetrates through the protective shell and is fixed with the fourth gear. A heat dissipation mechanism is arranged on the protective shell. A dust prevention mechanism is arranged on the protective shell.

[0008] By adopting the above technical solution, the output end of the drive motor drives Gear 1, Gear 1 drives Gear 2, Gear 2 drives Gear 3, Gear 3 drives Gear 4, and Gear 4 drives the drive rod, enabling the compressor to operate at high speed. At the same time, Gear 2 drives the heat dissipation mechanism to work, and the heat dissipation mechanism extracts the heat inside the protective case, so that the drive motor can drive the compressor at high speed, improving the working efficiency of the compressor, and reducing the influence of the heat generated by the transmission between gears on normal operation.

[0009] Further, the heat dissipation mechanism includes a support rod arranged on the protective case. A heat dissipation opening is provided on the protective case. The support rod is located inside the heat dissipation opening and is fixedly connected to the protective case. A heat dissipation fan is rotatably connected to the support rod. A drive assembly is arranged between the heat dissipation fan and Gear 2. A plurality of evenly distributed air inlet openings are provided at one end of the protective case away from the heat dissipation opening.

[0010] By adopting the above technical solution, Gear 2 drives the drive assembly, the drive assembly drives the heat dissipation fan on the support rod, and the heat dissipation fan extracts the hot air in the protective case from the heat dissipation opening, so that the heat generated by the high-speed operation of several gears in the protective case can be discharged from the protective case, reducing the influence of high temperature on the gears.

[0011] Further, the drive assembly includes a first transmission wheel fixed on Gear 2. The first transmission wheel is rotatably connected to the protective case. A second transmission wheel is fixed on the support rod. The second transmission wheel penetrates the support rod and is fixedly connected to the heat dissipation fan. A transmission belt is drivingly connected between the first transmission wheel and the second transmission wheel.

[0012] By adopting the above technical solution, Gear 2 drives the first transmission wheel, and the first transmission wheel drives the second transmission wheel by means of the transmission belt, so that it is convenient for the second transmission wheel to drive the heat dissipation fan to rotate.

[0013] Further, a protective pipe is fixed on the heat dissipation opening. The protective pipe corresponds to the heat dissipation opening. A protective net is fixed on the protective pipe.

[0014] By adopting the above technical solution, the protective pipe and the protective net cover the heat dissipation opening, so that it can play a protective role without affecting heat dissipation.

[0015] Further, the dust prevention mechanism includes a dust-proof cover arranged on the protective case. A plurality of evenly distributed filter holes are provided on the dust-proof cover. Two symmetric connecting plates are fixed on the dust-proof cover. A clamping component is arranged between the connecting plates and the protective case.

[0016] By adopting the above technical solution, the two connecting plates on the dust cover are fixed to the protective shell using a snap-on assembly. The outside air passes through the dust cover and then enters the protective shell from the air inlet, so that the dust cover can protect the air inlet on the protective shell and reduce the possibility of dust entering the protective shell and affecting the operation of the gears.

[0017] Furthermore, the clamping assembly includes a resistance block fixed on the protective shell, the resistance block is slidably connected with a clamping block, and the connecting plate is provided with a clamping groove corresponding to the clamping block.

[0018] By adopting the above technical solution, when the connecting plate contacts the contact block, the clamping block is inserted into the clamping groove on the connecting plate through the contact block, so that the connecting plate can be easily fixed and disassembled.

[0019] Furthermore, a support spring is provided between one end of the clamping block away from the connecting plate and the abutment block, and both ends of the support spring are fixedly connected to the abutment block and the clamping block.

[0020] By adopting the above technical solution, the support spring is used to limit the clamping block, so that the possibility of the clamping block falling off can be reduced when the clamping block is inserted into the clamping groove.

[0021] Furthermore, an end of the clamping block close to the connecting plate is provided with an abutting inclined surface, and the abutting inclined surface corresponds to the edge of the connecting plate.

[0022] By adopting the above technical solution, when installing the connecting plate, the edge of the connecting plate contacts the contact slope on the clamping block, and then the contact slope is moved. After the clamping block is aligned with the clamping groove, the clamping block is inserted into the clamping groove under the push of the supporting spring, thereby facilitating the insertion of the clamping block into the clamping groove.

[0023] In summary, the present application includes at least one of the following beneficial effects:

[0025] 2. In this application, when dissipating heat, the connecting plate on the dust-proof cover can be aligned with the abutting block on the protective case, and then the connecting plate is abutted against the abutting block. At the same time, the connecting plate abuts against the abutting slope on the clamping block, causing the clamping block to slide on the abutting block. Meanwhile, the clamping block pulls the supporting spring. When the clamping block is aligned with the clamping groove on the connecting plate, under the push of the supporting spring, the clamping block is inserted into the clamping groove to fix the connecting plate, thereby fixing the dust-proof cover on the protective case. Then, the outside air passes through the dust-proof holes on the dust-proof cover and enters the protective case from the air inlet, achieving the purpose of protecting the air inlet on the protective case with the dust-proof cover, reducing the possibility of dust entering the protective case and affecting the operation of the gears, and being convenient for disassembly and cleaning at the same time.
