Description

Technical Field

[0001] The utility model belongs to the technical field of chain saws and relates to a low-energy-consumption chain saw guide plate. Background Art

[0002] The chainsaw guide is a crucial component of the transmission system of an oil saw or electric chainsaw. Its primary function is to support and guide the saw chain. After the chainsaw guide and chain are installed, the output sprocket at the rear end of the chainsaw guide drives the chain, while the sprocket at the front end guides the chain's rotation, ensuring stable and accurate sawing, transmitting power, and reducing wear, providing strong support and assurance for the chainsaw's cutting operation. However, existing chainsaw guides often have a large front sprocket. This larger sprocket diameter affects the chain's rotation, reducing the chain's linear speed, resulting in reduced power transmission efficiency and increased energy consumption during chain sawing. Furthermore, the increased sprocket size directly increases the overall weight of the chainsaw guide, further increasing energy consumption during cutting. Utility Model Content

[0003] The purpose of the utility model is to provide a low-energy-consumption chain saw guide plate in response to the above problems.

[0004] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0005] The two guide wheels have a first end fixedly mounted on the front of the two guide wheels, the second end being fixedly mounted on the front of the two guide wheels, the second end being installed in a circle connected to the top of the two guide wheels, and the other end being connected to the top of the two guide wheels.

[0006] The smaller sprocket diameter can drive the chain to rotate faster, increase the linear speed, optimize the power transmission efficiency, and transmit the power to the chain more directly, reducing the loss of power during the transmission process, thereby improving the sawing efficiency and reducing energy consumption. The volume of the inner and outer guide plates is correspondingly reduced, making the chain saw guide bar lighter as a whole, further saving energy consumption during sawing.

[0007] In the above-mentioned low-energy chain saw guide plate, a small sprocket mounting hole is provided at the front end of the outer guide plate, one end of the small sprocket is mounted in the small sprocket mounting hole, and the distance between the small sprocket mounting hole and the front end of the outer guide plate is smaller than the radius of the small sprocket.

[0008] The small sprocket mounting hole at the front end of the outer guide plate is used for assembling the small sprocket.

[0009] In the above-mentioned low-energy-consumption chain saw guide bar, the small sprocket is an eight-tooth sprocket.

[0010] The design of the eight-tooth sprocket can increase the contact area between the sprocket and the chain, improve stability during sawing, and has strong durability. In addition, compared with sprockets with other numbers of teeth, the eight-tooth sprocket has higher efficiency in power transmission.

[0011] In the above-mentioned low-energy-consumption chain saw guide plate, an oil hole is provided between the groove and the chain saw mounting slot.

[0012] The oil hole is used to add grease, which can reduce the friction resistance inside the guide bar and make the chain saw more labor-saving during the sawing process, which helps to improve the sawing efficiency and reduce the energy consumption of the chain saw.

[0013] In the above-mentioned low-energy chain saw guide plate, the rear ends of the outer guide plate and the inner guide plate are provided with rear concave arc grooves, and the ends of the rear concave arc grooves and the side edges of the outer guide plate or the inner guide plate are chamfered.

[0014] The rear concave arc groove provides a clear guide path for the chain to run, ensuring that the chain can move stably along the predetermined track, preventing the chain from deflecting or jumping during the sawing process, and the chamfer improves assembly and positioning.

[0015] In the above-mentioned low-energy chain saw guide plate, the front end of the outer guide plate is provided with a front convex arc portion, the maximum width of the rear convex arc portion is greater than the maximum width of the front convex arc portion, and the distance between the front end of the rear convex arc portion and the rear end of the outer guide plate is less than the distance between the front end of the rear convex arc portion and the rear end of the front convex arc portion.

[0016] The maximum width of the rear convex arc portion is greater than the maximum width of the front convex arc portion, ensuring that the diameter of the output sprocket at the rear end of the outer guide plate is greater than the diameter of the small sprocket at the front end of the outer guide plate, so that the torque output of the chain during the sawing process is enhanced. The increase in torque not only enhances the climbing ability of the chain saw, but also optimizes its sawing efficiency and performance, which can further save energy consumption during sawing.

[0017] In the above-mentioned low-energy chain saw guide plate, the ratio of the maximum width of the rear convex arc portion to the maximum width of the front convex arc portion is 50.18:28.91, and the ratio of the distance between the front end of the rear convex arc portion and the rear end of the outer guide plate to the distance between the front end of the rear convex arc portion and the rear end of the front convex arc portion is 68.1:254.51.

[0018] In the above-mentioned low-energy chain saw guide plate, the ratio of the distance between the small sprocket mounting hole and the front end of the outer guide plate to the length of the outer guide plate is 13.64:336.25.

[0019] In the above-mentioned low-energy chain saw guide plate, the ratio of the length of the outer guide plate to the maximum width of the outer guide plate is 336.25:50.18, the ratio of the distance between the two first through holes on the outer guide plate to the maximum width of the outer guide plate is 25.8:50.18, and the ratio of the distance between the second through hole and the front end of the outer guide plate to the length of the outer guide plate is 64.05:336.25.

[0020] In the above-mentioned low-energy chain saw guide plate, the ratio of the horizontal distance between the oil hole and the first through hole to the distance between the first through hole and the rear end of the outer guide plate is 12:35.35.

[0021] Compared with existing technologies, the advantages of this utility model are: 1. The smaller sprocket diameter drives the chain faster, increasing linear speed and optimizing power transmission efficiency. It can transmit power more directly to the chain, reducing power loss during transmission, thereby improving sawing efficiency and reducing energy consumption. 2. The chain saw guide bar is lighter overall, further saving energy during sawing. BRIEF DESCRIPTION OF THE DRAWINGS

A strip hole 5 that penetrates the outer guide plates 1 and the inner guide plates 2 is provided between the two grooves 3. A second through hole 6 that penetrates the outer guide plates 1 and the inner guide plates 2 is provided between the strip hole 5 and the front end of the inner guide plate 2. A front concave arc groove 7 is provided at the front end of the inner guide plate 2, and a small sprocket 8 is provided in front of the front concave arc groove 7. The two ends of the small sprocket 8 are respectively arranged on the two outer guide plates 1, and the inner guide plate 2 is symmetrically arranged along its central axis, and the width of the inner guide plate 2 gradually widens from the front end to the front end of the groove 3, and the width of the inner guide plate 2 gradually narrows from the rear end of the groove 3 to the rear end of the inner guide plate 2. The outer guide plate 1 outside the groove 3 bulges outward to form a rear convex arc portion 9, and a chain saw mounting groove 10 is provided between the two sides of the inner guide plate 2 and the two outer guide plates 1, and the depth of the chain saw mounting groove 10 from the front end to the rear end is equal, that is, the distance between the side edge of the inner guide plate 2 and the side edge of the outer guide plate 1 except the groove 3 is equal.

[0027] In the present utility model, the chain is installed in the chain saw mounting groove 10 and cooperates with the small sprocket 8. The first through hole 4 on the outer guide plate 1 cooperates with the groove 3 of the inner guide plate 2. The second through hole 6 and the strip hole 5 on the outer guide plate 1 and the inner guide plate 2 respectively cooperate to facilitate the assembly between the outer guide plate 1 and the inner guide plate 2. The strip hole 5 on the inner guide plate 2 and the outer guide plate 1 facilitates the adjustment of the chain tension to avoid excessive heat generation due to excessive chain tension.

[0028] The diameter of the small sprocket 8 at the front end of the inner guide plate 2 is significantly smaller than that of the conventional sprocket. The smaller sprocket diameter of the small sprocket 8 can drive the chain to rotate faster, increase the linear speed, optimize the power transmission efficiency, and can transmit power to the chain more directly, reducing the loss of power during the transmission process, thereby improving the sawing efficiency and reducing energy consumption. The volume of the inner guide plate 2 and the outer guide plate 1 is correspondingly reduced, making the chain saw guide plate as a whole lighter, further saving energy consumption during sawing.

[0029] Specifically, combined Figure 1 As shown, a small sprocket mounting hole 11 is provided at the front end of the outer guide plate 1, and one end of the small sprocket 8 is installed in the small sprocket mounting hole 11. The distance between the small sprocket mounting hole 11 and the front end of the outer guide plate 1 is smaller than the radius of the small sprocket 8.

[0030] The small sprocket mounting hole 11 at the front end of the outer guide plate 1 is used to assemble the small sprocket 8. The radius of the small sprocket 8 is larger than the distance between the small sprocket mounting hole 11 and the front end of the outer guide plate 1, and some sprocket teeth of the small sprocket 8 are exposed from the front end of the outer guide plate 1.

[0031] Preferably, combined Figure 1 As shown, the small sprocket 8 is an eight-tooth sprocket.

[0032] The design of the eight-tooth sprocket can increase the contact area between the sprocket and the chain, improve stability during sawing, and has strong durability. In addition, compared with sprockets with other numbers of teeth, the eight-tooth sprocket has higher efficiency in power transmission.

[0033] Specifically, combined Figure 1 As shown, an oil hole 12 is provided between the groove 3 and the chain saw mounting groove 10 .

[0034] The oil hole 12 between the groove 3 and the chain saw mounting groove 10 is used for adding grease, which can reduce the friction resistance inside the guide plate and make the chain saw more labor-saving during the sawing process, which helps to improve the sawing efficiency and reduce the energy consumption of the chain saw.

[0035] Specifically, combined Figure 1 and Figure 3 As shown, a rear concave arc groove 13 is provided at the rear end of the outer guide plate 1 and the rear end of the inner guide plate 2, and a chamfer is provided between the end of the rear concave arc groove 13 and the side edge of the outer guide plate 1 or the side edge of the inner guide plate 2.

[0036] The rear concave arc groove 13 at the rear end of the outer guide plate 1 and the rear end of the inner guide plate 2 provides a clear guide path for the operation of the chain, ensuring that the chain can move stably along the predetermined trajectory, preventing the chain from deflecting or jumping during the sawing process, and the chamfering plays a role in improving assembly and positioning.

[0037] Specifically, combined Figure 1 As shown, the front end of the outer guide plate 1 is provided with a front convex arc portion 14, the maximum width of the rear convex arc portion 9 is greater than the maximum width of the front convex arc portion 14, the distance between the front end of the rear convex arc portion 9 and the rear end of the outer guide plate 1 is less than the distance between the front end of the rear convex arc portion 9 and the rear end of the front convex arc portion 14, the ratio of the maximum width of the rear convex arc portion 9 to the maximum width of the front convex arc portion 14 is 50.18:28.91, and the ratio of the distance between the front end of the rear convex arc portion 9 and the rear end of the outer guide plate 1 and the distance between the front end of the rear convex arc portion 9 and the rear end of the front convex arc portion 14 is 68.1:254.51.

[0038] The maximum width of the rear convex arc portion 9 is greater than the maximum width of the front convex arc portion 14, ensuring that the diameter of the output sprocket at the rear end of the outer guide plate 1 is greater than the diameter of the small sprocket 8 at the front end of the outer guide plate 1, so that the torque output of the chain during the sawing process is enhanced. The increase in torque not only enhances the climbing ability of the chain saw, but also optimizes its sawing efficiency and performance, which can further save energy consumption during sawing.

[0039] Specifically, combined Figure 1 As shown, the ratio of the distance between the small sprocket mounting hole 11 and the front end of the outer guide plate 1 to the length of the outer guide plate is 13.64:336.25.

[0040] Specifically, combined Figure 1As shown, the ratio of the length of the outer guide plate 1 to the maximum width of the outer guide plate 1 is 336.25:50.18, the ratio of the distance between the two first through holes 4 on the outer guide plate 1 to the maximum width of the outer guide plate 1 is 25.8:50.18, and the ratio of the distance between the second through hole 6 and the front end of the outer guide plate 1 to the length of the outer guide plate 1 is 64.05:336.25.

[0042] The working principle of the present invention is as follows: the chain is installed in the chain saw mounting groove 10 and cooperates with the small sprocket 8. The diameter of the small sprocket 8 is significantly smaller than that of the conventional sprocket. The smaller sprocket diameter of the small sprocket 8 can drive the chain to rotate faster, increase the linear speed, optimize the power transmission efficiency, and can transmit power to the chain more directly, reducing the loss of power during the transmission process, thereby improving the sawing efficiency and reducing energy consumption. The volume of the inner guide plate 2 and the outer guide plate 1 is correspondingly reduced, and the chain saw guide plate as a whole becomes lighter, further saving energy consumption during sawing.
