Technical Field
[0001] This invention relates to the field of chainsaw guide plates, specifically to a chainsaw guide plate head oil supply mechanism and the same. Background Technology
[0002] Chainsaw guide plates are the core support and guiding components of a chainsaw, also known as chainsaw guide plates. They are mainly used to support the saw chain, guide its cyclical operation, and work with the tensioning mechanism to adjust the chain tension, ensuring stable and efficient cutting operations. They are mostly made of high-strength alloys such as 65Mn manganese steel and often adopt a three-layer composite structure, balancing strength and lightweight. The core consists of the plate body, guide groove, guide wheel head, tail mounting base, and lubrication system. The guide plate specifications must be precisely matched with the saw chain. According to the structure, they can be divided into standard sprocket guide plates, fish belly-shaped guide plates, and double-sided flip-up guide plates. Among them, the double-sided flip-up model can extend the service life, while the professional model focuses on wear resistance and durability.
[0003] The chainsaw guide plate head oil supply mechanism is a key component for ensuring lubrication of the guide plate head and extending the equipment's lifespan. Its core function is to accurately deliver chain oil to the sprocket and bearing at the front end of the guide plate, solving the problems of friction and high temperature during high-speed operation. During operation, the chainsaw oil pump generates pressure and sends chain oil from the oil inlet at the tail of the guide plate into the main oil channel. The oil is then transported through the oil channel to the oil outlet at the head and sprayed onto the sprocket and bearing. With the help of the centrifugal force of the rotating sprocket, the oil film is diffused to the guide plate groove and the saw chain, achieving comprehensive lubrication and cooling.
[0004] In existing technologies, the oil supply mechanism at the head of a chainsaw guide plate generally adopts a traditional structure with a machine body oil pump for pressurization, long-distance oil delivery through the guide plate interlayer, and a single small-point oil outlet at the head. This excessively long oil supply path causes severe pressure attenuation at the end. The lubricating oil, starting from the chainsaw machine body oil pump, must pass through the oil inlet at the tail of the guide plate and the narrow main oil channel in the interlayer, with a total delivery distance reaching tens of centimeters. This process involves significant resistance and continuous pressure loss, resulting in a substantial pressure drop by the time the oil reaches the head outlet. Consequently, the oil output is weak and unstable. This insufficient pressure directly leads to the lubricating oil failing to adequately wet the needle rollers inside the sprocket. Ball bearings can only form a very thin oil film on their surface, or even no effective lubrication at all. The bearings are always in a state of boundary lubrication or even semi-dry friction, which leads to direct metal-to-metal contact friction, severe wear, a surge in frictional power consumption, and a rapid local temperature rise. This can cause the bearing to soften, seize, and lock up. At the same time, it can cause huge thermal stress and mechanical impact on the guide plate head, ultimately resulting in premature bearing failure, guide plate cracking and deformation, and chain derailment and breakage. This not only significantly shortens the service life of the equipment, but also poses serious safety hazards and greatly reduces the reliability and operational stability of the chainsaw. Summary of the Invention
[0005] Based on this, the purpose of the present invention is to provide a chainsaw guide head oil supply mechanism and a chainsaw guide plate thereof, so as to solve the technical problems in the background art mentioned above.

When the sprocket 23 rotates, it drives the multiple sets of limiting holes 24 to move, thereby driving the multiple sets of movable blocks 21 to move, which in turn drives the movable wheel 20 to rotate, and then drives the movable bevel gear ring 22 to rotate.
[0039] Please see Figure 1 - Figure 12 A second mounting chamber 26 is provided on the outer wall of the other side of the first clamping plate 1. A mounting plate 27 is installed on the outer end of the second mounting chamber 26, and multiple sets of bolts are used to fix the mounting plate 27 to the second mounting chamber 26.

When the movable bevel gear ring 22 rotates, it drives the movable bevel gear 30 to rotate, thereby driving the movable shaft 29 to rotate, and then driving the limit shaft 31 to rotate.
[0041] Please see Figure 7 - Figure 12 One end of the limiting shaft 31 is provided with a limiting block 32, and the outer wall of the limiting block 32 is movably connected to the inner hexagonal groove on one side of the outer wall of the transmission wheel 14. When the limiting shaft 31 rotates, it drives the limiting block 32 to rotate, thereby driving the transmission wheel 14 to rotate.
[0042] The working principle of this invention is as follows: When the chainsaw guide plate is produced and assembled, firstly, the operator installs the connecting shaft 10 and the transmission shaft 15 into the first mounting chamber 13, so that the connecting bevel gear 11 and the transmission bevel gear 16 are meshed. At the same time, the booster vortex 12 enters the docking groove 9. Then, the operator inserts the mounting base 8 from bottom to top into the first mounting port 17, so that the docking groove 9 is in contact with the oil passage 6. The booster vortex 12 enters one end of the oil passage 6. At the same time, one end of the transmission wheel 14 enters the reserved port 18. Then, the operator fixes the mounting base 8 into the first mounting port 17 with bolts. Next, the workers insert the movable wheel 20 into the second mounting port 19. Then, they install a toothed synchronous belt between the movable shaft 29 and the limiting shaft 31, so that the movable shaft 29 and the limiting shaft 31 are connected by the toothed synchronous belt. One end of the movable shaft 29 and one end of the limiting shaft 31 are respectively installed into the two sets of mounting holes 28. After that, the workers install the mounting plate 27 into the second mounting chamber 26, so that the movable bevel gear 30 meshes with the movable bevel gear ring 22. The mounting plate 27 is then fixed to the second mounting chamber 26 with multiple sets of bolts. After the mounting base 8 is fixed to the mounting plate 27, the worker installs the limiting wheel 25 into the sprocket 23. Then, the worker installs the limiting wheel 25 to one end of the second clamping plate 3 and aligns the first clamping plate 1, the guide plate body 2, and the second clamping plate 3 together. When the first clamping plate 1 is aligned with the guide plate body 2, the worker rotates the sprocket 23 and the transmission wheel 14, adjusting the position of the multiple sets of limiting holes 24 on one side of the outer wall of the sprocket 23 and the angle of the inner hexagonal groove on one side of the outer wall of the transmission wheel 14, so that the multiple sets of movable blocks 21... The chainsaw guide plate enters the interior of multiple sets of limiting holes 24, and the limiting block 32 enters the inner hexagonal groove on the outer wall of one side of the transmission wheel 14. Then, the workers fix the first clamping plate 1, the guide plate body 2 and the second clamping plate 3 with rivets. After the chainsaw guide plate is assembled, the workers install the chain to the outer end of the chainsaw guide plate, so that the inner wall of one end of the chain is movably connected to the outer wall of the sprocket 23. The chainsaw guide plate is assembled with the chainsaw host, so that the oil outlet of the oil pump inside the chainsaw host is connected to the oil inlet 5 at one end of the guide plate body 2. When the operator uses the chainsaw, the chain rotates, which in turn drives the sprocket 23 to rotate. Multiple sets of movable blocks 21 are connected to multiple sets of limiting holes 24, so the multiple sets of limiting blocks 21 rotate around the sprocket 23, thereby driving the movable wheel 20 to rotate, which in turn drives the movable bevel gear ring 22 to rotate. The movable bevel gear ring 22 meshes with the movable bevel gear 30, so the movable bevel gear 30 rotates, thereby driving the movable shaft 29 to rotate. The movable shaft 29 is connected to the limiting shaft 31 through a toothed synchronous belt, so the limiting shaft 31 rotates, thereby driving the limiting block 32 to rotate. When the limiting block 32 rotates, it connects with the hexagonal groove on the outer wall of the transmission wheel 14. Therefore, the transmission wheel 14 rotates, which in turn drives the transmission shaft 15 to rotate, and then drives the transmission bevel gear 16 to rotate. The transmission bevel gear 16 meshes with the connecting bevel gear 11, so the connecting bevel gear 11 rotates, which in turn drives the connecting shaft 10 to rotate, and then drives the booster vortex 12 to rotate, which boosts the pressure of the lubricating oil inside the oil circuit 6. The pressure of the lubricating oil is increased, and then the oil spray nozzle 7 sprays the lubricating oil onto the sprocket 23, so that the lubricating oil fully wets the needle rollers or ball bearings inside the sprocket, improving the lubricating oil spraying effect.
