Description

Technical Field

[0001] This utility model relates to the field of high-speed saw technology, specifically to a self-lubricating high-speed saw. Background Technology

[0002] In the wood processing industry and daily operations, equipment with saw chains as the core cutting component plays a crucial role. These devices typically rely on electric motors for power. Once the motor is running, power is transmitted to the drive shaft via a gearbox. The drive shaft then drives the drive gears, which in turn drive the saw chain at high speed along the guide plate, thus cutting the material. During operation, there is continuous and intense relative motion between the saw chain, the guide plate, and the drive gears. This relative motion generates significant friction, which not only consumes a large amount of energy, reducing equipment efficiency, but also causes severe wear between metal components. To reduce wear between metal components, improve equipment performance and reliability, extend the service life of critical components, and reduce equipment replacement costs, effective lubrication is essential. Lubrication forms a lubricating film on the surface of metal components, reducing direct contact between parts, thereby lowering the coefficient of friction and reducing wear.

[0003] Existing equipment has several drawbacks in its use, such as inadequate lubrication. Firstly, some equipment lacks a dedicated lubrication system, requiring operators to manually add lubricating oil periodically. This method is not only cumbersome but also makes it difficult to ensure timely and even lubrication. Operators may forget to add lubricating oil due to negligence or busy schedules, leading to insufficient lubrication and accelerated wear of components. Furthermore, manually adding lubricating oil makes it difficult to precisely control the amount and application location, easily resulting in wasted oil or localized insufficient lubrication. Utility Model Content

[0004] The purpose of this invention is to provide a self-lubricating high-speed saw that solves the problem that it is difficult to accurately control the amount and application location of lubricating oil when manually adding it, which can easily lead to waste of lubricating oil or insufficient lubrication in certain areas.

[0005] This utility model provides the following technical solution: a self-lubricating high-speed saw, including a housing frame, an electric motor fixed inside the housing frame, a gearbox fixed at the output end of the electric motor, a drive shaft fixedly connected to the output end of the gearbox, a drive gear fixedly connected to the outer wall of the drive shaft, a side housing frame fixed to one side of the housing frame, a guide plate fixedly connected to the inner side of the side housing frame, a saw chain wound around the outer wall of the guide plate, the drive gear meshing with the saw chain, and a lubrication component for lubricating the saw chain provided inside the drive gear.

[0006] As a preferred embodiment of the above technical solution, the lubrication assembly includes a cavity formed inside the drive gear, the cavity being filled with lubricating fluid, a plurality of oil outlet holes being arrayed on the side wall of the drive gear in contact with the saw chain, and a fluid guide tube for introducing lubricating fluid being embedded on one side of the drive gear.

[0007] As a preferred embodiment of the above technical solution, an oil storage tank is fixedly installed inside the outer casing, a solenoid valve is fixedly connected to one end of the oil storage tank, a control switch is connected to the solenoid valve, the control switch extends to the outside of the outer casing, a liquid delivery pipe is fixedly connected to the bottom of the oil storage tank, and a liquid inlet pipe is embedded on one side of the oil storage tank.

[0008] As a preferred embodiment of the above technical solution, a front baffle for blocking splashes is fixedly connected to one side of the upper end face of the outer casing.

[0009] As a preferred embodiment of the above technical solution, a battery pack for supplying power to the motor and solenoid valve is fixedly connected to one side of the lower end face of the housing frame.

[0010] As a preferred embodiment of the above technical solution, a rear handle is fixed to the upper end face of the housing frame, and a front handle is fixedly connected to the end of the motor located outside the housing frame.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] In this invention, after the electric motor starts running, it transmits power to the drive shaft through the gearbox. The drive shaft drives the drive gear to rotate. During the rotation of the drive gear, the lubrication component continuously provides lubrication to the saw chain, reducing friction between the saw chain and the guide plate and the drive gear, and reducing wear between metal parts. Over a long period of use, it can significantly reduce the wear of the saw chain, guide plate and drive gear, extend the service life of these key components and reduce equipment replacement costs.

[0019] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0020] Example

[0021] like Figures 1-5 As shown, this utility model provides a technical solution: a self-lubricating high-speed saw, including a housing frame 1, an electric motor 11 fixed inside the housing frame 1, a gearbox 12 fixed to the output end of the electric motor 11, a drive shaft 13 fixedly connected to the output end of the gearbox 12, a drive gear 14 fixedly connected to the outer wall of the drive shaft 13, a side housing frame 15 fixed to one side of the housing frame 1, a guide plate 16 fixedly connected to the inner side of the side housing frame 15, a saw chain 17 wound around the outer wall of the guide plate 16, the drive gear 14 meshing with the saw chain 17 for transmission, and a lubrication component 2 for lubricating the saw chain 17 provided inside the drive gear 14. During the process, pressing the start button of the motor 11 starts the motor 11 to run. The power is transmitted to the drive shaft 13 through the gearbox 12. The drive shaft 13 drives the drive gear 14 to rotate, and the drive gear 14 drives the saw chain 17 to rotate. Then the saw chain 17 is brought close to the object to be cut, so that the saw chain 17 contacts the object and applies appropriate pressure. Cutting is performed by the high-speed rotation of the saw chain 17. During the process of the drive shaft 13 driving the drive gear 14 to rotate, the lubrication component 2 will continuously provide lubrication to the saw chain 17, reduce the friction between the saw chain 17 and the guide plate 16 and the drive gear 14, reduce wear, and improve cutting efficiency.

[0022] As one implementation method in this embodiment, such as Figure 5As shown, the lubrication assembly 2 includes a cavity 21 opened inside the drive gear 14. The cavity 21 is used to fill lubricant. Multiple oil outlet holes 22 are arrayed on the side wall of the drive gear 14 that contacts the saw chain 17. A guide tube 23 for introducing lubricant is embedded on one side of the drive gear 14. In actual use, an appropriate amount of lubricant is filled into the cavity 21 inside the drive gear 14 through the guide tube 23. When the motor 11 starts and drives the drive gear 14 to rotate, the lubricant in the cavity 21 will move towards the side wall of the drive gear 14 that contacts the saw chain 17 under the action of centrifugal force due to the contact between the drive gear 14 and the saw chain 17. The lubricant seeping out from the oil outlet holes 22 will adhere to the chain links, chain teeth and other parts of the saw chain 17. As the saw chain 17 rotates at high speed, the lubricant will be evenly distributed on the contact surface between the saw chain 17 and the guide plate 16 and the drive gear 14.

[0023] As one implementation method in this embodiment, such as Figure 3 and Figure 5 As shown, an oil reservoir 31 is fixedly installed inside the outer casing 1. A solenoid valve 32 is fixedly connected to one end of the oil reservoir 31, and a control switch 33 is connected to the solenoid valve 32. The control switch 33 extends to the outside of the outer casing 1. A liquid delivery pipe 34 is fixedly connected to the bottom of the oil reservoir 31, and an inlet pipe 35 is embedded on one side of the oil reservoir 31. In actual use, when it is necessary to add lubricating fluid to the oil reservoir 31, the operator connects the external lubricating fluid supply device (such as a lubricating oil tank) to the inlet pipe 35. Since the inlet pipe 35 is embedded on one side of the oil reservoir 31, the lubricating fluid can flow smoothly into the oil reservoir 31 through the inlet pipe 35. After replenishment, the connection between the external lubricating fluid supply device and the inlet pipe 35 is disconnected. When it is necessary to supply lubricating fluid to the lubrication assembly 2, the operator... When the operator presses the control switch 33, the control switch 33 sends a signal to open the solenoid valve 32. At this time, the lubricating fluid in the oil tank 31 flows out through the liquid delivery pipe 34 fixedly connected at the bottom under its own weight or slight pressure, and then pours onto the drive shaft 13. The drive shaft 13 moves by tilting the main body of the device and then slowly starting the saw chain 17. This can lubricate the drive gear 14 and the saw chain 17. (This method can quickly lubricate but cannot be used during the high-speed operation of the high-speed saw. Therefore, it can be used according to the actual situation. For example, if the high-speed saw has been idle for too long and the internal mechanism has become stuck due to excessive friction during the initial low-speed operation, quick lubrication can be performed. If there is no obvious jamming, lubrication can be performed through the lubrication component 2.)

[0024] As one implementation method in this embodiment, such as Figure 1As shown, a front baffle 18 for blocking splashes is fixedly connected to one side of the upper end face of the housing frame 1, and a battery pack 19 for powering the motor 11 and solenoid valve 32 is fixedly connected to one side of the lower end face of the housing frame 1. A rear handle 101 is fixedly fixed to the upper end face of the housing frame 1, and a front handle 102 is fixedly connected to the end of the motor 11 located outside the housing frame 1. In actual use, the operator holds the front handle 102 and the rear handle 101 firmly with both hands to pick up the high-speed saw. Press the power switch on the battery pack 19. At this time, the power indicator light will light up, indicating that the motor 11 and solenoid valve 32 are powered on. The front baffle 18 provides reliable protection for the operator and effectively blocks the splashes generated during the cutting process.

[0025] Working principle: Before using the equipment, fill an appropriate amount of lubricant into the cavity 21 inside the drive gear 14 through the liquid guide tube 23. When the motor 11 starts and drives the drive gear 14 to rotate, the lubricant in the cavity 21 will move towards the side wall where the drive gear 14 contacts the saw chain 17 under the action of centrifugal force due to the contact between the drive gear 14 and the saw chain 17. The lubricant seeping out from the oil outlet 22 will adhere to the chain links, chain teeth and other parts of the saw chain 17. As the saw chain 17 rotates at high speed, the lubricant will be evenly distributed on the contact surface between the saw chain 17 and the guide plate 16 and the drive gear 14.

[0026] The above embodiments are only used to illustrate the technical solution of this utility model, and are not intended to limit it.
