Description

Technical Field

[0001] The invention relates to the technical field of chain oiling devices, and in particular to a toothed chain high-pressure oiling device and a use method thereof. Background Art

[0002] Through the analysis of the causes of wear failure of toothed chains, a large amount of data has proved that 65% of the reasons are caused by the lack of effective oil film protection in the initial stage of the hinge pair.

[0003] The reason for the above phenomenon is: compared with other types of chains, the hinge gap of the toothed chain is very small. The ordinary oiling method makes it difficult for the oil to penetrate evenly into the tiny gap of the hinge, and it is even more difficult to form a protective oil film in the tiny gap. Therefore, the toothed chain works for a long time without the protection of the oil film, resulting in rapid wear.

[0004] During the wear process, the hinge pair of the toothed chain generates a large amount of heat, causing metal dry friction and causing the chain to stretch rapidly. Although patent documents disclose the technology of oiling by negative pressure vacuum, the actual use effect is not ideal. The reason is that vacuum negative pressure oiling is affected by the viscosity of the oil, and the adsorption of the tiny gap of the hinge is poor.

[0005] In summary, to solve the oiling problem of the toothed chain hinge pair, it is necessary to make systematic improvements to the oiling solution. Summary of the invention

[0028] like Figure 1 As shown, a sealing bolt 17 is provided in the wear-resistant oil inlet 1, and a first filtering mechanism 3 is also provided in the horizontal direction at the top of the oil tank body. The wear-resistant oil added from the wear-resistant oil inlet 1 enters the bottom of the oil tank body through the first filtering mechanism 3, and soaks the chain part to be oiled on the traction sprocket 15 and the tensioning wheel 11 that are connected to the transmission.

[0033] In this embodiment, Figure 1 As shown, by spraying high-pressure oil directly onto the hinge pair of the chain through an oil spray nozzle, the wear-resistant oil can enter the tiny gap of the hinge pair under the pressure of the spray, thereby coating the tiny gap of the hinge pair with a wear-resistant oil film.

[0038] Embodiment 4,

[0039] This embodiment is an improvement made on the basis of Embodiment 3, specifically:

[0040] like Figure 1 As shown, the oiling mechanism also includes an oil blowing device, which includes a second air pipe 19 connected to the first air pipe 18 at one end, the second air pipe 19 passes through the side wall of the oil tank body and is connected to a high-pressure gas nozzle 14 at the other end inside the oil tank body, and the high-pressure gas nozzle 14 is opposite to the chain located on the side of the chain discharge port 21.

[0041] In this embodiment, the oil blowing device can be used to blow away excess wear-resistant oil from the chain before it is discharged, so as to avoid wasting the wear-resistant oil.

[0042] Embodiment 5,

[0043] This embodiment is an improvement made on the basis of Embodiment 4, specifically:

[0044] like Figure 1 As shown, a second filter mechanism 9 is also provided on one side of the bottom of the oil tank body, and the second filter mechanism 9 is communicated with the inside of the oil tank body and connected to the high-pressure oil pump 7 through an oil pipe;

[0045] like Figure 1 As shown, a third filtering mechanism 22 is further provided at the bottom of the discharge box 28 , and an oil drain pipe 23 is provided at the bottom end of the discharge box 28 . The oil drain pipe 23 is provided with a valve and is connected to a filtered oil recovery box 24 .

[0046] In this embodiment, the second filter mechanism 9 may be a circulation filter, and the third filter mechanism 22 may be a filter sponge; by providing the second filter mechanism 9 and the third filter mechanism 22, the recovery and recycling of the wear-resistant oil can be fully realized.

[0047] Embodiment 6,

[0048] This embodiment is an improvement made on the basis of Embodiment 5, specifically:

[0049] A method for using a high-pressure oiling device for a toothed chain, comprising the following steps: Step 1, installing the chain, adding wear-resistant oil, and performing primary filtration: after the chain to be oiled is installed, the wear-resistant oil is added through the wear-resistant oil inlet 1, and after being filtered and removed by a first filtering mechanism to remove impurities, the wear-resistant oil enters the bottom of the oil tank body and partially soaks the chain; Step 2, reducing the viscosity of the wear-resistant oil by a heating device 29: starting the heating device, observing the temperature index through a display, heating the wear-resistant oil in the oil tank body to a specified temperature, and then turning off the heating device after the viscosity of the wear-resistant oil decreases. ; Step 3, start the high-pressure air pump 20 for high-pressure oiling: tighten the sealing bolt 17, close the valve on the oil drain pipe 23, allow the high-pressure gas to enter the oil tank body through the first air pipe 18, and observe the pressure gauge 16 to make the specified pressure in the oil tank body; Step 4, start the high-pressure oil pump 7 for high-pressure oil injection; Step 5, start the drive motor 26 and the vibration motor 10, so that the chain is oiled in a running-in state under the action of the vibrating wear-resistant oil; Step 6, after the oiling is completed, take out the chain: the oiled chain is cooled to room temperature in the discharge box 28 and then taken out.

[0050] In this embodiment, installing the chain means opening the sealing door of the feed box 28 and the oil tank body, and gradually installing the chain; the function of the heating device is to reduce the viscosity of the wear-resistant oil, so as to facilitate the wear-resistant oil to enter the tiny gap of the chain hinge pair. Due to the different types of wear-resistant oil, the temperature required for heating by the heating device is also different, so the specific heating temperature is not limited.

[0051] Furthermore, in the present embodiment, a specific description is given of the method of oiling the toothed chain, namely, the wear-resistant oil needs to be heated to reduce the viscosity before the multiple oiling procedure is started. The multiple oiling refers to oiling through a high-pressure air pump 20 and a high-pressure oil pump 7, wherein the former enables the oiling pressure to be reached in the oil tank body, thereby promoting the wear-resistant oil to enter the tiny gap of the chain hinge pair. Since the viscosity of the wear-resistant oil is reduced, it is easy to form an oil film in the tiny gap of the hinge pair under high pressure, while the latter oils by high-pressure injection through an oil nozzle. Due to the injection pressure, the wear-resistant oil can easily enter the tiny gap of the hinge pair. At the same time, since a second filtering mechanism 9 is provided, the sprayed wear-resistant oil still undergoes a high-temperature step to reduce the viscosity, and thus the sprayed wear-resistant oil can enter the tiny gap of the chain hinge pair under a low-viscosity state to form an oil film.

[0052] Furthermore, the multiple oiling procedures involved in this embodiment also include running-in oiling and vibration oiling. In the running-in state, the hinge pair of the chain realizes relative movement between the hinge pair parts, thereby causing the air pressure in the tiny gap to change dynamically, which is conducive to the rapid entry of wear-resistant oil; during the vibration oiling process, the wear-resistant oil generates impact force through vibration, making it easier for the wear-resistant oil to enter the tiny gap of the hinge pair.

[0053] Embodiment 7,

[0054] This embodiment is an improvement made on the basis of Embodiment 6, specifically:

[0055] In step 3, the pressure in the fuel tank is 0.95 MPa;

[0056] In the step 4, the injection pressure of the high-pressure oil pump 7 is 0.75 MPa.

[0057] Embodiment 8,

[0058] This embodiment is an improvement made on the basis of Embodiment 6, specifically:

[0059] In step 3, the pressure in the fuel tank is 1.25 MPa;

[0060] In the step 4, the injection pressure of the high-pressure oil pump 7 is 0.95 MPa.

[0061] The use principle of the present invention:

[0062] In view of the special structural characteristics of the toothed chain, the present invention makes improvements to the oiling device and oiling method of the toothed chain, and its principles are embodied in the following aspects:

[0063] A. Determine the idea of ​​"first reduce the viscosity of wear-resistant oil, then oiling", and improve the structure of the oiling device;

[0064] B. Determine that the lubrication method is mainly high-pressure lubrication, and divide the high-pressure lubrication into high-pressure lubrication in the fuel tank body and lubrication by high-pressure oil injection;

[0065] C. On the basis of high-pressure lubrication, running-in lubrication and vibration lubrication are also used as auxiliary.

[0066] In summary, the present invention combines a variety of oiling methods to solve the problem that the gap of the hinge pair of the toothed chain is too small to be oiled on the basis of reducing the viscosity of the wear-resistant oil. By improving the oiling device and setting special steps of the oiling method, an oil film layer can be formed in the tiny gap of the chain hinge pair before the toothed chain enters the use state, thereby avoiding premature wear of the toothed chain and effectively extending the service life of the toothed chain.
