DETAILED DESCRIPTION
[0029] The following is a combination of the appended examples of the present invention Figure 1-3 , clearly and completely describes the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts shall fall within the scope of protection of the present invention.
[0030] Example:
[0031] like Figures 1 to 3 As shown, a high-efficiency wear-resistant reducer includes a housing 11, a mounting cavity 12 is defined in the housing 11, a plurality of transmission components (not shown) are mounted in the mounting cavity 12, and a plurality of temperature monitors 31 are mounted on the side walls of the mounting cavity 12 to monitor whether the temperature in the mounting cavity 12 changes. When the external temperature is constant, when there is a lack of lubrication between the transmission components, the temperature in the mounting cavity 12 will rise, so that the temperature monitor 31 can determine whether the transmission components need lubrication based on the temperature change.
[0032] A base 17 is fixedly provided on the upper side of the housing 11, and an oil storage tank 14 is installed on the upper side of the base 17. An oil storage chamber 18 is provided in the oil storage tank 14, and an oil inlet pipe 15 is fixedly connected to the rear side wall of the oil storage chamber 18. The oil inlet pipe 15 is connected to an oil storage device (not shown in the figure). An oil spray pipe 13 for spraying oil lubrication on the surface of the transmission component is provided in the upper side wall of the installation cavity 12. The lower edge of the curved side wall of the oil spray pipe 13 is provided with a plurality of oil spray holes that penetrate the upper side wall of the installation cavity 12. 25. An oil delivery pipe 16 connected to the oil injection pipe 13 is fixedly connected to the left side wall of the oil storage chamber 18, and an oil squeezing assembly is installed in the oil storage chamber 18. Lubricating oil enters the oil storage chamber 18 through the oil inlet pipe 15, and under the squeezing of the oil squeezing assembly, enters the oil injection pipe 13 through the oil delivery pipe 16, and is then sprayed out through the oil spray hole 25 and sprayed onto the surface of each transmission component, thereby lubricating the transmission components in the installation cavity 12 to enhance the wear resistance of the transmission components.
[0033] The specific structure of the oil squeezing assembly is as follows: the oil squeezing assembly includes a piston plate 19, which is slidably connected to the oil storage chamber 18 from left to right. A drive rod 20 is hinged to the right side of the piston plate 19. A drive wheel 21 is installed in the oil storage chamber 18. The side of the drive rod 20 away from the piston plate 19 is eccentrically hinged to the drive wheel 21. A mounting frame 22 is fixed to the base 17. A motor 23 for driving the drive wheel 21 to rotate is installed on the mounting frame 22. The output shaft end of the motor 23 extends into the oil storage chamber 18 and is fixedly connected to the drive wheel 21. The motor 23 is connected to the temperature monitor 31 via an electrical signal.
[0034] The motor 23 drives the driving wheel 21 to rotate so that the driving wheel 21 can drive one side of the driving rod 20 to swing eccentrically with it, so that the driving rod 20 drives the piston plate 19 to perform a left and right reciprocating piston motion in the oil storage chamber 18, thereby pressurizing the lubricating oil in the oil storage chamber 18 to make it become a high-pressure and high-speed liquid flow and flow into the oil spray pipe 13, and then sprayed on the surface of the transmission component through the oil spray hole 25. In addition, a one-way valve 24 is installed on the oil inlet pipe 15 and the oil delivery pipe 16 to prevent the oil from flowing back.
[0035] In order to make the lubricating oil droplets sprayed from the oil spray hole 25 finer, thereby evenly and comprehensively lubricating the transmission components in the installation cavity 12, embodiment 2 is proposed here: the oil spray hole 25 is a trumpet-shaped slot hole that gradually expands from top to bottom. When the oil enters the oil spray hole 25, the cross-sectional area of the oil spray hole 25 increases, resulting in a decrease in the oil flow rate, so that a local low-pressure area is formed in the oil spray hole 25, thereby intensifying the turbulence intensity inside the oil, causing the oil to be further broken into smaller droplets due to turbulent disturbance when leaving the nozzle, and then the oil becomes a fine oil mist after leaving the oil spray hole 25, so as to ensure that each of the transmission components in the installation cavity 12 can be evenly and comprehensively lubricated.
[0036] In order to facilitate the recovery of the lubricating oil in the installation cavity 12, a third embodiment is proposed herein: a long slope 26 and a short slope 27 are respectively provided on the left and right sides of the bottom wall of the installation cavity 12. An oil leakage groove 28 that penetrates the bottom wall of the installation cavity 12 is provided at the intersection of the lower edges of the long slope 26 and the short slope 27. A placement rack 29 is fixedly provided on the lower side of the housing 11. An oil receiving box 30 is placed in the placement rack 29. The oil receiving box 30 is located directly below the oil leakage groove 28.
[0037] The oil on the surface of each transmission component drips downward onto the surface of the long slope 26 and the short slope 27, and flows downward along the slope of the long slope 26 and the short slope 27 into the oil leakage groove 28, and finally gathers in the oil collecting box 30, so that technicians can take it away and recycle it, thereby effectively saving costs.
[0038] The working principle of the present utility model is as follows: under the condition of constant temperature of the environment outside the housing 11, when the temperature monitor 31 detects that the temperature in the installation cavity 12 has increased significantly, an electrical signal is transmitted to the motor 23, so that the piston plate 19 pressurizes the lubricating oil into the oil spray pipe 13, and evenly sprays the lubricating oil onto the surface of each transmission component through the oil spray hole 25. After the oil spray hole sprays the oil mist on the transmission component for a fixed time, the piston plate 19 stops supplying lubricating oil to the oil spray pipe 13 to stop the lubrication operation, and the working procedure of the piston plate 19 is set to be at intervals for a period of time to avoid the piston plate 19 from operating multiple times without interruption.
[0039] It should be noted that the temperature monitor 31 is Figure 2 In addition to the installation position shown, several temperature monitors 30 are installed on the side wall of the installation cavity 12 near the gear meshing area and the bearing position to avoid monitoring distortion caused by position deviation of the temperature monitor 30.
[0040] It should be noted that, in another embodiment of the oil squeezing assembly, the piston plate 19 can be controlled only by time, that is, the piston plate 19 automatically runs a cycle after a certain time interval.
[0041] Excess oil on the surface of each transmission component drips onto the surface of the long slope 26 and the short slope 27 and then flows down into the oil leakage groove 28, and is collected in the oil receiving box 30 so that technicians can recycle and reuse it, thereby further saving costs and improving economic benefits.
[0042] It should also be pointed out that the terms indicated in the present invention, such as: "front", "rear", "vertical", "horizontal", etc., indicating the orientation or position relationship are based on the orientation or position relationship shown in the accompanying drawings, which is only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, it cannot be understood as limiting the scope of protection of the present invention.
[0043] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
