[0002] The saw chain guide, also known as the chain plate or guide bar, is an important part of the saw chain transmission system. It mainly provides support and guidance for the saw chain to ensure that the saw chain can move smoothly and at high speed. The saw chain can cut trees during high-speed movement. During cutting, the saw chain will be under significant pressure. In this case, lack of lubrication will cause the saw chain to be damaged quickly. Therefore, most saw chains are lubricated with lubricating oil.

[0003] However, the existing lubricating oil is supplied by the oil supply unit of the logging equipment, and the lubricating oil is applied from the guide plate to the saw chain to lubricate the saw chain, and then the saw chain carries the lubricating oil to the parts of the saw chain guide plate that need lubrication for lubrication. This method causes the lubricating oil to move at high speed with the saw chain, and splash out when the saw chain passes through the driven end, so that the driven end drive wheel is often not fully lubricated, and the lower part of the saw chain that contacts the wood cutting is also difficult to lubricate, resulting in poor cooling effect of the saw chain, which affects the life of the saw chain.

[0053] The following is a detailed description in conjunction with the accompanying drawings and specific implementations. In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention can be implemented in many other ways different from those described herein, and those skilled in the art can make similar generalizations without violating the connotation of the present invention, so the present invention is not limited by the specific embodiments disclosed below.

[0054] The saw chain guide bar lubrication system of the present application can be applicable to occasions such as saw chain lubrication, and of course can also be used in other similar application scenarios. The saw chain guide bar lubrication system is described in detail below.

[0055] Example 1 See attached Figure 1 — Fig.12 As shown, a schematic diagram of the structure of a preferred embodiment of the saw chain guide lubrication system of the present application is shown. The saw chain guide lubrication system comprises a guide body 1, a driven support structure 2 is provided on one end of the guide body 1, a rotating structure 3 is installed on the driven support structure 2, and a transmission wheel 4 is installed on the rotating structure 3; wherein, a saw chain guide groove 11 is provided on the side of the guide body 1, and the saw chain guide groove 11 is used to guide the lateral movement of the saw chain; an oil delivery channel 5 is provided on the guide body 1 and the driven support structure 2, one end of the oil delivery channel 5 is connected to the oil supply unit of the logging equipment, and the other end of the oil delivery channel 5 is connected to the rotating structure 4.

[0056] The present invention guides the pressurized lubricating oil provided by the oil supply unit to lubricate the rotating structure 3 by setting the oil delivery channel 5. Compared with the existing method of directly lubricating the saw chain, the present application first delivers the lubricating oil to the rotating structure 3 through the oil delivery channel 5. After lubricating the rotating structure 3, the rotating structure 3 applies the lubricating oil to the saw chain, which can effectively ensure that the lubricating oil lubricates the rolling element 32 and prolongs the service life of the rotating structure 3. The lubricating oil after the rotating structure 3 is lubricated lubricates the saw chain after leaving the rotating structure 3. At this time, the saw chain is at the reversing position of the driven end. With the rotation of the transmission wheel, the lubricating oil will splash the lubricating oil onto the saw chain without dead angles. After part of the lubricating oil is thrown onto the saw chain after the reversing, the lubricating oil at this time will not be thrown away due to the centrifugal force of the reversing, so that the contact part of the saw chain with the tree can also be lubricated, and the utilization rate of the lubricating oil can be improved at the same time.

[0057] See attached Figure 5 — Fig.10 As shown, in the present invention, the height of the rotating structure 3 is greater than the groove width of the saw chain guide groove 11; the rotating structure 3 includes an inner support body 31, a rolling member 32 arranged around the inner support body 31, and an outer ring body 33 mounted on the rolling member 32 and arranged concentrically with the inner support body 31; the transmission wheel 4 is installed on the outer ring body 33.

[0058] The present invention increases the bearing capacity of the rotating structure 3 and prevents damage due to excessive bearing capacity by setting the height of the rotating structure 3 to be greater than the groove width of the saw chain guide groove 11; the inner support body 31 is set as the rotation center; the outer ring body 33 is set to isolate the transmission wheel 4 and the rolling element 32 so that the sprocket drives the outer ring body 33 to rotate through the outer ring body 33, so that when the transmission wheel 4 rotates, the outer ring body 33 and the rolling element 32 are subjected to rolling friction, ensuring that the bearing capacity of the rolling element 32 is uniform, avoiding local friction of the rolling element 32, and extending the service life of the rolling element 32.

[0059] See attached Figure 8 — Fig.10 As shown, in the present invention, the height of the inner support body 31, the rolling element 32 and the outer ring body 33 is greater than the groove width of the saw chain guide groove 11; the outer ring body 33 is provided with oil injection holes 332 at equal angles, the inner support body 31 is provided with an oil storage cavity 311, and the inner support body 31 is provided with a through hole 312 connected to the oil storage cavity 311.

[0060] The present invention increases the contact area between the rolling element 32 and the inner support body 31 and the outer ring body 33 by limiting the height of the rolling element 32 to be greater than the width of the saw chain guide groove 11, thereby improving the bearing capacity of the rolling element 32, preventing the rolling element 32 from being damaged due to being in a high-load state for a long time, and extending the service life of the rolling element 32; the oil storage chamber 311 is set to temporarily store the lubricating oil in the oil delivery channel 5, and the through hole 312 is combined to allow the lubricating oil to enter between the outer ring body 33 and the inner support body 31 through the oil delivery channel 5 to lubricate the rolling of the rolling element 32, reduce the friction of the rolling element 32 during the rolling process, reduce the wear of the rolling element 32, and extend the service life of the rolling element 32; the oil injection hole 332 is set to allow the lubricating oil to flow out through the oil injection hole 332 to cool the transmission wheel 4, and can flow along the transmission wheel 4 to cool and lubricate the saw chain.

[0061] See attached Figure 8 — Fig.10 As shown, in the present invention, covers 34 are provided on both ends of the inner support body 31, and the rolling element 32 is located between the two covers 34; grooves 35 corresponding to the covers 34 are provided on both ends of the outer ring body 33; the ratio of the height of the rolling element 32 to the width of the saw chain guide groove 11 is less than or equal to 2.

[0062] The present invention blocks the lubricating oil by setting the cover 34 to prevent the lubricating oil from flowing out directly, prolongs the residence time of the lubricating oil, cooperates with the inner support body 31 and the outer ring body 33 to form a space for temporary storage of the lubricating oil, ensures that the rolling element 32 is immersed in the lubricating oil, and the entire rolling element 32 is lubricated by the lubricating oil during the rolling process, reduces the friction of the rolling element 32, and prolongs the service life of the rolling element 32; by setting the groove 35, the cover 34 is avoided to ensure the flatness of the top and bottom surfaces of the entire rotating structure 3; by limiting the ratio of the height of the rolling element 32 and the width of the saw chain guide groove 11, it is prevented that the rolling element 32 is too high and the thickness of the driven support structure 2 is too small, which affects the service life of the driven support structure 2. At the same time, the cover 34 can be cooperated with the outer ring body 33 to limit the axial direction of the outer ring body 33. The cover 34 and the inner support body 31 are interference fit, and even one of the covers 34 can be integrally formed with the inner support body 31.

[0063] See attached Figure 4 and Figure 5 As shown, in the present invention, the oil delivery channel 5 includes an oil guide main channel 51 arranged on the guide plate body 1, two oil inlet channels 52 arranged on one end of the guide plate body 1 away from the driven support structure 2, an oil inlet port 53 arranged perpendicular to the oil inlet channel 52, an oil guide connecting channel 54 arranged on the driven support structure 2 and connected to the oil guide main channel 51, and an oil outlet port 55 arranged perpendicular to the oil guide connecting channel 54, and the oil outlet port 55 faces the rotating structure 3.

[0064] The present invention guides the flow direction of the lubricating oil by setting the main oil guide channel 51, so that the lubricating oil reaches the designated position, that is, the rotating structure 3; by setting the oil inlet channel 52 and the oil inlet port 53, the oil supply unit can supply the lubricating oil into the main oil guide channel 51, and by setting two oil inlet channels 52 and two oil inlet ports 53, the guide plate body 1 can be flipped for use, that is, after the guide plate body 1 is used for a long time, one side of the guide plate body 1 will be worn, and the entire guide plate can be flipped at this time to allow the other side to perform logging operations; by setting the oil outlet 55, the oil outlet 55 is connected to the oil storage chamber 311, so that the lubricating oil in the main oil guide channel 51 flows out and flows into the oil storage chamber 311 of the rotating structure 3 to lubricate the rotating structure 3.

[0065] It should be specially noted that the main oil guide channel 51 and the oil inlet channel 52 in the oil delivery channel 5 of the present application are first grooved on the guide plate body 1, and after the groove processing is completed, metal blocks of matching and the same material are used for welding at the groove to form a channel inside the guide plate body 1; the oil inlet 53 and the oil outlet 55 are formed by drilling and welding metal blocks, and the oil guide connecting channel 54 is formed by the same processing method of first grooving and then welding; in addition, pipelines can be laid in the channel to ensure the direction of lubricating oil flow during oil delivery, and metal debris on the groove wall during the grooving process can be effectively prevented from flowing with the lubricating oil, affecting the subsequent rotation of the rotating structure 3, thereby providing further protection for the rotating structure 3.

[0066] See attached Figure 1 — Fig.13 As shown, in the present invention, the driven support structure 2 includes two support plates 21 installed on one end of the guide plate body 1, and the support plate 21 is provided with a first groove 22 for installing the rotating structure 3, and the transmission wheel 4 is sleeved on the outer wall of the rotating structure 3; the minimum spacing between the two support plates 21 is equal to the width of the saw chain guide groove 11; the oil guide communication channel 54 and the oil outlet 55 are arranged on the support plate 21, and the oil outlet 55 is located in the first groove 22.

[0067] The present invention supports and limits the rotating structure 3 by setting the support plate 21; avoids the rotating structure 3 by setting the first groove 22 to prevent the height of the rotating structure 3 from being too high and affecting the installation of the support plate 21, and avoids the thickness of the support plate 21 from being greater than the link width of the saw chain to avoid jamming during use; by limiting the minimum distance between the two support plates 21, it is ensured that the two support plates 21 can guide the saw chain; by limiting the position of the oil outlet 55, the lubricating oil flowing out of the oil outlet 55 can flow into the oil storage chamber 311.

[0068] See attached Figure 1 — Figure 7 As shown, in the present invention, the guide plate body 1 is provided with a first sealing groove 12 , in which a first sealing ring 13 is installed. The first sealing groove 12 is located at the channel opening of the oil guide main channel 51 close to the oil guide connecting channel 54 .

[0069] The present invention can effectively prevent lubricating oil from flowing out from the connection between the oil guide main channel 51 and the oil guide connecting channel 54 by providing the first sealing groove 12 and the first sealing ring 13 .

[0070] See attached Figure 1 — Fig.12 As shown, the operation of the lubrication system of the present invention is as follows: First, the oil supply unit on the logging equipment provides pressurized oil to enter the oil inlet channel 52 through the oil inlet port 53 in the oil delivery channel 5, flows along the oil inlet channel 52 to the oil guide main channel 51, enters the oil guide connecting channel 54 along the oil guide main channel 51, and finally flows out from the oil outlet port 55 in the oil delivery channel 5 into the space between the inner support body 31 and the outer ring body 33, that is, the space where the rolling element 32 is located. As the lubricating oil continues to enter, and because the lubricating oil is a solid lubricating oil such as high-temperature lithium-based grease, the lubricating oil will not flow out immediately, but will gradually increase. When the lubricating oil is full, After the rolling element 32 is located in the space, the lubricating oil will continue to enter the control unit. At this time, the lubricating oil in the control unit will flow out through the through hole 312 and enter the space between the outer ring body 33 and the inner support body 31, that is, the rolling element 32 is lubricated, so that the rolling element 32 is in the lubricating oil during the rotation. As the lubricating oil fills the space between the outer ring body 33 and the inner support body 31, it will eventually spray out from the oil spray hole 332 and contact the transmission wheel 4. The centrifugal force generated by the rotation of the transmission wheel 4 will throw the lubricating oil away, and the thrown lubricating oil will contact the saw chain to lubricate and cool the saw chain.

[0071] It should be noted that when the saw chain guide is in use, there will be a clamping plate on the oil supply unit to clamp the saw chain guide. Therefore, it is necessary to ensure that the oil supply port on the oil supply unit is connected to one of the oil inlets 53, and the extra oil inlet 53 will be blocked by clamping the clamping plate. The transmission wheel 4 in the present application can be a groove sprocket or a tooth sprocket.

[0072] Example 2 See attached Fig.13 — Fig.16 As shown, the difference between this embodiment and the above-mentioned embodiment is that, in this embodiment, the driven support structure 2 includes a connecting plate 201 arranged on one end of the guide bar body 1, a mounting plate 202 integrally formed with the connecting plate 201, a through hole 203 arranged on the mounting plate 202, and the rotating structure 3 is fixedly installed in the through hole 203, and the connecting plate 201 is integrally formed with the guide bar body 1 or fixedly connected by riveting; wherein, the thickness of the connecting plate 201 is equal to or greater than the thickness of the guide bar body 1, and the thickness of the connecting plate 201 is less than the width of the sawing path of the saw chain; the thickness of the mounting plate 202 is less than the thickness of the guide bar body 1, and the guide bar body 1 is symmetrically arranged with respect to the mounting plate 202.

[0073] In this embodiment, the mounting plate 202 is connected to the guide bar body 1 by setting a connecting plate 201, and the guide bar body 1 is symmetrically set with respect to the connecting plate 201, so as to ensure that the distances from the connecting plate 201 and the mounting plate 202 to the top and bottom surfaces of the guide bar body 1 are equal, and by limiting the thickness of the connecting plate 201 to be smaller than the saw path width generated by the movement of the saw chain, it is possible to effectively prevent the saw from getting stuck during logging operations; in this embodiment, a through hole 203 is set to provide an installation position for the rotating structure 3, and when the rotating structure 3 is installed, the outer ring body 33 in the rotating structure 3 is fixedly mounted on the hole wall of the through hole 203, and the outer ring body 33 is limited by the cover 34, and since the cover 34 and the inner support body 31 are interference fit, even one of the covers 34 can be integrally formed with the inner support body 31, so that the inner support body 31 can be fixed.

[0074] See attached Fig.13 — Fig.16 As shown, in this embodiment, a first lubrication hole 331 is provided on the outer ring body 33; the transmission wheel 4 is composed of two rotating plates 41 with the same structure, and the two rotating plates 41 are respectively installed on the two ends of the rotating structure 3; the rotating plate 41 is a circular plate, and the minimum spacing between the two rotating plates 41 is equal to the groove width of the saw chain guide groove 11, and the maximum spacing between the two rotating plates 41 is not greater than the thickness of the mounting plate 202, and a second groove 42 corresponding to the rotating structure 3 is provided at the center position of the rotating plate 41.

[0075] In this embodiment, the first lubrication hole 331 is provided to communicate with the oil delivery channel 5, so as to ensure that the lubricating oil can enter the space between the outer ring body 33 and the inner support body 31 to lubricate the rolling element 32; by providing the rotating plates 41 at both ends of the rotating structure 3, that is, installing the rotating plates 41 at both ends of the inner support body 31, the saw chain can be limited and guided by the two rotating plates 41; by providing the rotating plates 41 as circular plates, when guiding the saw chain, the distance between the center position and the saw chain will not change, so the tensioning force on the saw chain will not change, which can effectively prevent the saw chain from breaking, and the circular setting makes the distance moved by the lubricating oil from the center of the rotating plate 41 due to centrifugal force as equal as possible, so as to effectively ensure that the lubricating oil is not affected by the centrifugal force. The uniformity of the centrifugal force when it is thrown onto the saw chain can evenly lubricate the saw chain; by limiting the maximum distance and the minimum distance between the two rotating plates 41, it is ensured that the spacing between the rotating plates 41 will not be too large, which will affect the guide limitation of the saw chain, and ensure that it will not get stuck during the logging process. It should be noted that the maximum distance between the two rotating plates 41 is determined by the top and bottom surfaces of the two rotating plates 41. Specifically, the distance from the top surface of one rotating plate 41 to the bottom surface of the other rotating plate 41, and the two sets of distances obtained are the maximum distance and the minimum distance; by setting the second groove 42, an installation position is provided for the rotating structure 3, and the rotating structure 3 is avoided to prevent the height of the rotating structure 3 from affecting the overall thickness.

[0076] Example 3 See attached Fig.17 It is shown that the difference between this embodiment and the above embodiment is that, in this embodiment, the oil delivery channel 5 includes an oil delivery hole 501 set through the guide plate body 1, an oil inlet hole 502 set on the guide plate body 1, a blocking block 503 installed on one end of the oil delivery hole 501 close to the oil inlet hole 502, and an output oil hole 504 set on the driven support structure 2.

[0077] This embodiment adopts a punching method to set a hole that penetrates the guide plate body 1 as a guide channel for the lubricating oil. Compared with the above-mentioned embodiment using a slotting method, this embodiment saves the welding process, reduces material loss, and can save the subsequent treatment of welding slag and welding marks generated by welding; through the setting of the blocking block 503, the opening of the oil delivery hole 501 is blocked to ensure that the lubricating oil can only move in the direction of the output oil hole 504.

[0078] Example 4 See attached Fig.18As shown, the difference between this embodiment and the above embodiment is that in this embodiment, heat dissipation holes 341 are provided at equal intervals on the cover 34. The heat dissipation holes 341 can be round holes, waist-shaped holes, or can be provided on the edge of the cover 34 to form a groove structure.

[0079] The heat dissipation holes 341 of this embodiment can effectively increase the speed at which the lubricating oil flows out of the space formed by the outer ring body 33 and the inner support body 31, thereby increasing the cooling effect on the rolling element 32. It should be noted that the lubricating oil used here is different from the solid lubricating oil. In the absence of pressure, the lubricating oil will not flow out directly from the heat dissipation holes 341, thereby ensuring that the rolling element 32 rolls in the lubricating oil.

[0080] Example 5 See attached Fig.19 As shown, the difference between this embodiment and the above-mentioned embodiment is that, in this embodiment, limiting grooves 43 corresponding to the saw chain are provided at equal intervals on the arc surfaces of two rotating plates 41 whose interval is smaller than that of the saw chain guide groove 11 .

[0081] In this embodiment, the limiting grooves 43 are arranged to correspond to the transmission plates on the saw chain, so that the original friction transmission is changed to the limiting transmission, the transmission efficiency is improved, and the wear caused by friction between the saw chain and the transmission wheel 4 is reduced, thereby extending the service life of the saw chain and the transmission wheel 4. It should be particularly noted that the minimum distance between the two rotating plates 41 provided with the limiting grooves 43 is less than the groove width of the saw chain guide groove 11.

[0082] Example 6 See attached Fig. 20 and Fig.21 As shown, the difference between this embodiment and the above-mentioned embodiment is that, in this embodiment, a thickening ring 411 is provided on the transmission circular plate 41 , and the clamping groove 43 is provided on the outer ring wall of the thickening ring 411 .

[0083] It should be noted that the mounting plate 202 is provided with an avoidance groove corresponding to the thickening ring 411. In this embodiment, the distance between the two transmission circular plates 41 is reduced by the thickening ring 411, ensuring that the middle guide teeth of the saw chain can cooperate with the transmission circular plate 41; in this embodiment, only the outer end of the transmission circular plate 41 is thickened by the thickening ring 411, and the thickness of the mounting plate 202 only needs to be partially reduced, thereby ensuring the bearing strength of the mounting plate 202 and extending the service life of the mounting plate 202.

[0084] The above embodiments are intended to illustrate the present application, not to limit the present application. Any solution that is a simple transformation of the present application falls within the protection scope of the present application.
