Description

Technical Field

[0001] This utility model relates to the field of saw chain technology, and in particular to a saw chain. Background Technology

[0002] Currently, chainsaws are mainly used for logging and timber processing. Their working principle is based on the lateral movement of the interlaced blades on the chainsaw to perform the cutting action. During the operation of the chainsaw, it is necessary to lubricate the chainsaw with lubricating oil to prevent the chainsaw from overheating and wearing due to friction.

[0003] In the prior art, there is no lubricating oil through groove on the saw chain drive blade. For example, in the published document CN218639863U, the contact surface between the friction part and the bottom surface of the guide plate groove is a plane to extend the service life between the saw chain and the guide plate. However, an oil film cannot be formed on its surface, and it cannot provide lubrication during operation, resulting in local oil shortage, incomplete oil film, and increased friction coefficient and wear rate. Utility Model Content

[0009] In the above scheme, preferably, the drive plate is provided with a through lubricating oil through hole.

[0010] In the above scheme, preferably, there is a distance G between the center hole of the tank and the center hole of the lubricating oil through hole, and the distance G ranges from 0.2mm to 1mm.

[0011] In the above scheme, preferably, the tank has a volume E, and the volume E ranges from 0.03 mm³ to 0.05 mm³.

[0012] In the above scheme, preferably, the average range of the volume E is 0.04 mm³.

[0013] In the above scheme, preferably, at least two grooves are provided on the side of the drive plate.

[0014] In the above scheme, preferably, the left cutting tooth chain piece, the right cutting tooth chain piece, the connecting piece, and the driving piece are all provided with corresponding chain shaft holes.

[0022] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments: Example 1: See Figures 1-6 A saw chain includes a saw chain body, which is composed of a left cutting tooth chain piece 2, a right cutting tooth chain piece 3, a connecting piece 4, a driving piece 5, and a chain shaft 6. The left cutting tooth chain piece 2, the right cutting tooth chain piece 3, the connecting piece 4, and the driving piece 5 are all provided with corresponding chain shaft holes 11 and are riveted together by the chain shaft 6.

[0023] In this embodiment, the drive plate 5 has a plurality of grooves 7 on its side, and at least two grooves 7 are provided on the side of the drive plate 5. Each groove 7 has a volume E and is filled with lubricating oil. The main function of the lubricating oil is to form an oil film between the mechanical parts to reduce the direct contact between the metals, thereby reducing wear and friction resistance, and can play the roles of cooling, cleaning, rust prevention and sealing.

[0024] The groove 7 has an average diameter D and a maximum depth T. The average diameter D of the groove 7 ranges from 0.5 mm, and the maximum depth T of the groove 7 ranges from 0.05 mm.

The center hole of the outermost groove 7 has a distance F between the outer edge 8 of the drive plate 5 and the outer edge 8 of the drive plate 5. The distance F is 1 mm.

[0025] The lubricating oil through hole 9 on the saw chain drive plate 5 is mainly used to lubricate the gears inside the guide plate, and automatically delivers lubricating oil to the friction surface when needed to improve lubrication conditions and reduce wear. Through the filling of lubricating oil in the lubricating oil through hole 9 and the groove 7, the lubricating oil is evenly distributed to each friction part of the saw chain to form an oil film to reduce friction and extend service life.

[0026] Example 2: See Figures 1-6 A saw chain includes a saw chain body, which is composed of a left cutting tooth chain piece 2, a right cutting tooth chain piece 3, a connecting piece 4, a driving piece 5, and a chain shaft 6. The left cutting tooth chain piece 2, the right cutting tooth chain piece 3, the connecting piece 4, and the driving piece 5 are all provided with corresponding chain shaft holes 11 and are riveted together by the chain shaft 6.

[0027] In this embodiment, the drive plate 5 has a plurality of grooves 7 on its side, and at least two grooves 7 are provided on the side of the drive plate 5. Each groove 7 has a volume E and is filled with lubricating oil. The main function of the lubricating oil is to form an oil film between the mechanical parts to reduce the direct contact between the metals, thereby reducing wear and friction resistance, and can play the roles of cooling, cleaning, rust prevention and sealing.

[0028] The groove 7 has an average diameter D and a maximum depth T. The average diameter D of the groove 7 is in the range of 1 mm, and the maximum depth T of the groove 7 is in the range of 0.1 mm. There is a distance G between the center hole of the groove 7 and the center hole of the lubricating oil through hole 9. The distance G is in the range of 0.6 mm. The groove 7 has a volume E. The volume E is in the range of 0.04 mm³. The center hole of the outermost groove 7 is in the range of 1 mm with the outer edge 8 of the drive plate 5.

[0029] The lubricating oil through hole 9 on the saw chain drive plate 5 is mainly used to lubricate the gears inside the guide plate, and automatically delivers lubricating oil to the friction surface when needed to improve lubrication conditions and reduce wear. Through the filling of lubricating oil in the lubricating oil through hole 9 and the groove 7, the lubricating oil is evenly distributed to each friction part of the saw chain to form an oil film to reduce friction and extend service life.

[0030] Example 3: See Figures 1-6 A saw chain includes a saw chain body, which is composed of a left cutting tooth chain piece 2, a right cutting tooth chain piece 3, a connecting piece 4, a driving piece 5, and a chain shaft 6. The left cutting tooth chain piece 2, the right cutting tooth chain piece 3, the connecting piece 4, and the driving piece 5 are all provided with corresponding chain shaft holes 11 and are riveted together by the chain shaft 6.

[0031] In this embodiment, the drive plate 5 has a plurality of grooves 7 on its side, and at least two grooves 7 are provided on the side of the drive plate 5. Each groove 7 has a volume E and is filled with lubricating oil. The main function of the lubricating oil is to form an oil film between the mechanical parts to reduce the direct contact between the metals, thereby reducing wear and friction resistance, and can play the roles of cooling, cleaning, rust prevention and sealing.

[0032] The groove 7 has an average diameter D and a maximum depth T. The average diameter D of the groove 7 ranges from 1.5 mm, and the maximum depth T of the groove 7 ranges from 0.15 mm. There is a distance G between the center hole of the groove 7 and the center hole of the lubricating oil through hole 9. The distance G ranges from 0.4 mm. The groove 7 has a volume E, which ranges from 0.04 mm³. The center hole of the outermost groove 7 has a distance F between the outer edge 8 of the drive plate 5 and the outer edge 8 of the drive plate 5. The distance F is 1 mm.

[0033] The lubricating oil through hole 9 on the saw chain drive plate 5 is mainly used to lubricate the gears inside the guide plate, and automatically delivers lubricating oil to the friction surface when needed to improve lubrication conditions and reduce wear. Through the filling of lubricating oil in the lubricating oil through hole 9 and the groove 7, the lubricating oil is evenly distributed to each friction part of the saw chain to form an oil film to reduce friction and extend service life.

[0034] During operation, the lubricating oil in the lubricating oil through hole 9 and the lubricating oil in the groove 7 together provide a continuous oil surface between the mechanical parts to avoid oil loss. Lubricating oil should be added every 30 minutes to 1 hour, and the specific frequency should be adjusted according to the intensity of use. Each time oil is added, attention should be paid to the amount of oil to ensure that the chain is fully lubricated but not over-lubricated. Add oil through the special oil filling port on the chainsaw chain to avoid oil overflow.
