Description

Technical Field

[0001] The utility model relates to the technical field of the drive of a four-sided planer, in particular to a two-stage gear bevel gear reducer. Background Technique

[0002] A four-sided planer is a planer product in the category of woodworking machines, mainly used for processing wood products such as wooden squares, wooden boards, decorative wood strips, and wooden floors, and performing planing treatment on the upper and side surfaces of the wood. Excellent four-sided planers generally have a compact structure, a workbench surface plated with hard chromium, and are durable. As an important component of the four-sided planer, the two-stage gear bevel gear reducer mainly plays the role of reducing the rotational speed of the output shaft.

[0003] Chinese Patent with the authorization announcement number CN213685124U discloses a two-stage gear bevel gear reducer for supporting a four-sided planer, including a gear box. A drive speed change component is fixedly installed inside the gear box. One side of the top of the gear box is fixedly installed with a lubricating oil tank. One side of the lubricating oil tank is fixedly installed with an oil pump. The output end of the oil pump is sleeved and installed with a lubricating component. The bottom of the gear box is fixedly installed with a shock absorption component. The bottom of the shock absorption component is fixedly installed with an installation component. In the utility model, an oil pump fixedly installed on one side of the lubricating oil tank adds lubricating oil through the oil inlet. The oil pipe is connected to the oil pump. The oil pump leads the lubricating oil into the lubricating pipeline, and the oil outlet sprays the lubricating oil on the surfaces of the first gear set and the second gear set to play a lubricating role.

Detailed implementation mode

[0017] Embodiment 1

[0018] As Figures 1 to 3 shown, a two-stage gear bevel gear reducer proposed by the present utility model includes a gearbox body 1, a heat preservation box 2, a temperature sensor 3, a floating plate 302 and a heat dissipation mechanism; a drive speed change assembly is arranged inside the gearbox body 1; the heat preservation box 2 is installed outside the gearbox body 1 and is communicated with the bottom end of the gearbox body 1, and a tempered glass observation window 201 is arranged on the side wall of the heat preservation box 2, and a scale 202 is arranged on one side of the tempered glass observation window 201; the temperature sensor 3 is installed on the top end of the heat preservation box 2; the floating plate 302 is arranged inside the heat preservation box 2, a detection probe 303 is installed on the floating plate 302, and a connecting wire 301 is connected between the detection probe 303 and the temperature sensor 3; the heat dissipation mechanism is arranged on the gearbox body 1 and is used for timely discharging and cooling the heat of the lubricating oil inside the gearbox body 1.

[0019] Furthermore, a first oil passage 101 and a second oil passage 204 are respectively opened at the bottom ends of the side walls of the gearbox body 1 and the heat preservation box 2, and the first oil passage 101 is communicated with the second oil passage 204 for the passage of lubricating oil, so that the heights of the lubricating oil in the gearbox body 1 and the heat preservation box 2 are kept consistent, which is convenient for intuitively observing the amount of lubricating oil inside the gearbox body 1.

[0020] Furthermore, a mounting seat 203 is detachably installed at the top end of the heat preservation box 2 through bolts, which is convenient for disassembling and assembling the mounting seat 203 and the heat preservation box 2, and the temperature sensor 3 and the detection probe 303 can be taken out for maintenance and replacement; a sealing ring is arranged at the connection between the mounting seat 203 and the heat preservation box 2, which is convenient for improving the sealing performance of the connection and avoiding the leakage of lubricating oil.

[0021] In this embodiment, an appropriate amount of lubricating oil is added into the gearbox body 1 to start the driving and speed-changing assembly. The lubricating oil inside the gearbox body 1 enters the heat preservation box 2 through the first oil passage 101 and the second oil passage 204, so that the height of the lubricating oil in the heat preservation box 2 is the same as that in the gearbox body 1. And through the toughened glass observation window 201 and the scale 202, the height of the lubricating oil in the heat preservation box 2 can be visually observed, and then the height of the lubricating oil inside the gearbox body 1 can be known, so that the lubricating oil inside the gearbox body 1 can be replenished in time to avoid damage to the driving and speed-changing assembly. The floating plate 302 rises or falls following the lubricating oil inside the heat preservation box 2, driving the detection probe 303 to monitor the temperature of the lubricating oil inside the heat preservation box 2 in real time. The detection probe 303 transmits the monitoring information to the temperature sensor 3 through the connecting wire 301, and the temperature sensor 3 transmits the detection information to the controller. The heat dissipation mechanism is started through the controller to dissipate the heat of the lubricating oil inside the gearbox body 1, avoiding the normal operation of the driving and speed-changing assembly being interfered by too high oil temperature and prolonging the service life.

[0022] Embodiment 2

[0023] As Figure 1 and Figure 3 shown, a two-stage gear bevel gear reducer proposed by the present utility model, compared with Embodiment 1, the heat dissipation mechanism includes a conduction rod 5, a heat absorption plate 501, heat dissipation fins 502 and a protection net 4; multiple groups of conduction rods 5 are provided, and multiple groups of conduction rods 5 are evenly installed on the gearbox body 1; the heat absorption plate 501 is installed between one ends of multiple groups of conduction rods 5 and is not located inside the gearbox body 1; the heat dissipation fins 502 are installed between the other ends of multiple groups of conduction rods 5 and are located outside the gearbox body 1; the protection net 4 is detachably installed on the outside of the gearbox body 1 through bolts, and the protection net 4 surrounds the outside of the heat dissipation fins 502. A fan 504 is installed inside the protection net 4 through a bracket 503, and the fan 504 is attached to the heat dissipation fins 502.

[0024] Furthermore, the conduction rod 5 is made of copper rod, and the heat absorption plate 501 is made of copper plate. Copper material is not easy to be corroded and polluted by lubricating oil and has strong thermal conductivity. The heat of the lubricating oil inside the gearbox body 1 is absorbed by the heat absorption plate 501 and transmitted to the external heat dissipation fins 502 through the conduction rod 5, and is dissipated to the outside through the heat dissipation fins 502, accelerating the cooling of the lubricating oil and avoiding interfering with the normal operation of the driving and speed-changing assembly inside the gearbox body 1 and prolonging the service life.

[0025] In this embodiment, when the detection probe 303 detects that the lubricating oil temperature in the incubator 2 exceeds the set safety threshold, the detection information is transmitted to the controller, and the controller starts the fan 504 to accelerate the discharge of the heat on the heat dissipation fins 502 into the air, further accelerating the heat dissipation and cooling of the lubricating oil inside the gearbox body 1. The setting of the protective net 4 facilitates the protection of the fan 504 and the heat dissipation fins 502, avoiding scalding the staff by the heat dissipation fins 502 and also avoiding damage to the fan 504.

[0026] The embodiments of the present invention have been described in detail above in conjunction with the accompanying drawings. However, the present invention is not limited thereto. Various changes can be made within the scope of knowledge of those skilled in the art without departing from the purpose of the present invention.
