Description

Technical Field

[0001] This utility model relates to the field of transmission component technology, specifically to a high-pressure cleaner with helical gear transmission. Background Technology

[0002] A high-pressure washer is a machine that uses a power unit to drive a high-pressure plunger pump to generate high-pressure water to wash the surface of an object. Current high-pressure washers generally use spur gears for internal transmission; however, spur gear transmissions have high friction, resulting in higher noise levels and a relatively shorter lifespan. Utility Model Content

[0003] In view of the above-mentioned shortcomings of the existing technology, the present invention provides a high-pressure cleaner with helical gear transmission, which can effectively solve the problems of high noise and short life of existing high-pressure cleaners.

[0004] To achieve the above objectives, this utility model provides the following technical solution:

[0005] This utility model provides a high-pressure cleaner with helical gear transmission, including a drive motor, and further comprising:

[0006] The transmission assembly includes a transmission box installed at the output end of a drive motor. The transmission box contains a first helical gear and a second helical gear that mesh with each other, and the first helical gear is installed at the output end of the drive motor.

[0007] The self-lubricating component includes a lubrication frame installed in the transmission box. The transmission box is provided with a piston tube and an oil storage tube for conveying lubricating oil. When the second helical gear rotates, the piston tube draws lubricating oil from the oil storage tube into the lubrication frame, and at the same time draws lubricating oil from the bottom wall of the transmission box into the oil storage tube.

[0008] Furthermore, a drive shaft is rotatably mounted in the transmission box, and the second helical gear is mounted on the drive shaft.

[0009] Furthermore, a transmission disc is fixedly installed at the top of the drive shaft, and an output shaft is movably inserted above the transmission disc. When the transmission disc rotates, the output shaft moves up and down reciprocally.

[0010] Furthermore, the self-lubricating assembly also includes a piston rod movably inserted into one end of the piston tube, a transmission plate fixedly installed at one end of the piston rod, the bottom end of the drive shaft movably penetrating through the inner wall of the transmission box, a cam fixedly installed at one end of the drive shaft located outside the transmission box, the cam and the transmission plate being slidably connected, an oil outlet pipe being connected between the piston tube and the lubrication frame, and an oil inlet pipe being connected between the piston tube and the oil storage pipe.

[0011] Furthermore, a groove is provided on the side wall of the cam, and a slider that matches the groove is provided on the cam.

[0012] Furthermore, the inner bottom wall of the transmission box is provided with an inclined groove, and an oil return pipe is inserted into the oil storage pipe, with the end of the oil return pipe away from the oil storage pipe extending through the outer wall of the transmission box to the inclined groove.

[0013] The technical solution provided by this utility model has the following advantages compared with the known prior art:

[0014] Replacing the spur gear drive with a helical gear can reduce noise and extend the service life of the equipment. Secondly, during the helical gear drive process, the piston tube will draw lubricating oil from the oil storage pipe and deliver it to the lubrication frame to add lubricating oil to the helical gear, further improving the transmission quality. At the same time, excess lubricating oil will be recovered to improve the lubrication effect. Attached Figure Description

[0020] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0021] The present invention will be further described below with reference to the embodiments.

[0022] Example: Reference Figure 1 A high-pressure washer with helical gear transmission includes a drive motor 1 and a transmission assembly, including a transmission box 2 installed at the output end of the drive motor 1. The transmission box 2 has a first helical gear 4 and a second helical gear 5 that mesh with each other. The first helical gear 4 is installed at the output end of the drive motor 1. A drive shaft 6 is rotatably installed in the transmission box 2. The second helical gear 5 is installed on the drive shaft 6. A transmission disc 7 is fixedly installed at the top of the drive shaft 6. An output shaft 8 is movably inserted above the transmission disc 7. When the transmission disc 7 rotates, the output shaft 8 moves up and down reciprocally. A conveying pipe 3 is provided at the top of the transmission box 2.

[0023] like Figure 1 and Figure 2 As shown, the transmission box 2 is equipped with a first helical gear 4 and a second helical gear 5, which replace the original flat gear transmission. In comparison, the helical gear has lower transmission noise and better transmission effect, thereby extending the overall service life of the equipment.

[0024] The drive motor 1 drives the output shaft 8 to slide up and down repeatedly via helical gear transmission. During the up-and-down sliding of the output shaft 8, the delivery pipe 3 is connected to the inlet pipe and the outlet pipe respectively (e.g., Figure 2 As shown, the water source is drawn from the external source by the up and down sliding of the output shaft 8. The above-mentioned function of drawing water source is existing technology and will not be described in detail.

[0025] refer to Figure 3 The transmission box 2 is equipped with a self-lubricating component, including a lubrication frame 17 installed inside the transmission box 2. The transmission box 2 is externally equipped with a piston tube 12 for conveying lubricating oil and an oil reservoir 14. When the second helical gear 5 rotates, the piston tube 12 draws lubricating oil from the oil reservoir 14 into the lubrication frame 17, and simultaneously draws lubricating oil from the bottom wall of the transmission box 2 into the oil reservoir 14. The self-lubricating component also includes a piston rod 13 movably inserted into one end of the piston tube 12. A transmission plate 11 is fixedly installed at one end of the piston rod 13, and the bottom end of the drive shaft 6 movably penetrates the interior of the transmission box 2. A cam 9 is fixedly installed at one end of the drive shaft 6 located outside the transmission box 2. The cam 9 and the transmission plate 11 are slidably connected. A groove 10 is provided on the side wall of the cam 9. A slider that matches the groove 10 is provided on the cam 9. An oil outlet pipe 16 is connected between the piston tube 12 and the lubrication frame 17. An oil inlet pipe 15 is connected between the piston tube 12 and the oil storage pipe 14. An inclined groove is provided on the inner bottom wall of the transmission box 2. An oil return pipe 18 is inserted into the oil storage pipe 14, and the end of the oil return pipe 18 away from the oil storage pipe 14 extends through the outer wall of the transmission box 2 to the inclined groove.

[0026] When the first helical gear 4 and the second helical gear 5 are in operation, the cam 9 is driven to rotate via the drive shaft 6. During the rotation of the cam 9, the transmission plate 11 is driven to slide back and forth using the slide groove 10 and the slider, thereby driving the piston rod 13 to slide back and forth in the piston tube 12. One-way valves are respectively installed on the oil outlet pipe 16 and the oil inlet pipe 15. During the reciprocating sliding process, the piston rod 13 draws lubricating oil from the oil storage pipe 14 into the piston tube 12, and then delivers it from the piston tube 12 to the lubrication frame 17. The lubrication frame 17 is equipped with multiple nozzles that spray lubricating oil onto the second helical gear 5, achieving a rapid and continuous lubrication effect along with the transmission of the first helical gear 4 and the second helical gear 5.

[0027] Excess lubricating oil drips onto the bottom wall of the transmission box 2 and concentrates in the inclined groove under the action of gravity. When the piston tube 12 draws lubricating oil from the oil storage tube 14, the air pressure in the oil storage tube 14 decreases, so the return oil tube 18 is used to draw lubricating oil from the inclined groove and return the excess lubricating oil to the oil storage tube 14, thereby achieving full utilization of the lubricating oil.

[0028] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the embodiments of this utility model.
