Description

Technical Field

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

[0002] A gearbox is a mechanism used to change the speed and torque from the engine. It can change the transmission ratio between the output shaft and the input shaft in a fixed or progressive manner. A gearbox consists of a transmission mechanism and a control mechanism. Some cars also have a power output mechanism. Most transmission mechanisms use ordinary gear transmissions, while some use planetary gear transmissions. Ordinary gear transmission transmission mechanisms generally use sliding gears and synchronizers, etc.

[0003] In existing transmissions, gears are typically lubricated by the splashing of lubricating oil. Some transmissions use a small oil pump to draw lubricating oil from the bottom of the transmission to the top and spray it out. However, using an oil pump is cumbersome to maintain, and the normal operation of the oil pump can be affected by the deterioration of the oil quality. Therefore, we propose a self-lubricating transmission gear. Utility Model Content

[0005] Therefore, the technical solution adopted by this utility model is as follows:

[0006] A self-lubricating gearbox gear includes: a housing assembly and a lubrication assembly disposed within the housing assembly. The housing assembly includes a gearbox body and a gear shaft assembly disposed within the gearbox body. The lubrication assembly includes a mounting mechanism disposed at the bottom of the gearbox body, a lubrication mechanism connected to the mounting mechanism, and a filter mechanism disposed at the end of the lubrication mechanism. The lubrication mechanism includes a mounting bracket mounted at the bottom of the gearbox body, a transmission gear assembled on the mounting bracket and meshing with the gear shaft assembly, a connecting rod connected to the middle of the transmission gear, a screw disposed at the middle of the connecting rod, a compression cylinder connected to the mounting mechanism and located outside the screw, a connecting pipe connected to the end of the compression cylinder, an upper oil flow channel opened on the gearbox body and connected to the connecting pipe, and a nozzle connected to the upper oil flow channel and located at the top of the gearbox body.

[0012] In a preferred embodiment, the present invention can be further configured such that: the bottom of the gearbox body is provided with an oil change hole connected to the upper oil flow channel.

[0013] The above-mentioned technical solution of this utility model has the following beneficial technical effects:

[0014] 1. This utility model, through a lubrication component, utilizes a gear shaft assembly to drive the transmission gear to rotate, which in turn drives the screw to rotate inside the compression cylinder. This allows the lubricating oil overflowing the compression cylinder to enter the compression cylinder and move towards one end of the connecting pipe under compression. In this way, the lubricating oil enters the upper oil flow channel and flows upward, and is then sprayed out from the nozzle to lubricate the gear shaft assembly below. Compared with splash lubrication and oil pump lubrication, this solution not only provides more thorough lubrication, but is also simpler and more convenient to use and maintain, making it easier to promote and use.

[0015] 2. This utility model uses a lubrication assembly to fix the compression cylinder using a mounting base, spring, and support rod. The connection and fixing position can be adaptively adjusted according to the installation height of the compression cylinder, making it highly practical.

[0016] 3. This utility model uses a lubrication assembly to filter the lubricating oil entering the compression cylinder using a filter cylinder. At the same time, when the connecting rod rotates, it drives the vibrating ball on the insertion rod to strike the filter cylinder, causing the filtered residue to fall into the filter box, thus achieving the collection of impurities in the lubricating oil and ensuring the effectiveness of the lubricating oil.

[0023] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be noted that, unless otherwise specified, the embodiments and features of the present utility model can be combined with each other.

[0024] The following describes, with reference to the accompanying drawings, some embodiments of a self-lubricating gearbox gear provided by this utility model.

[0025] Combination Figure 1-2 As shown, the present invention provides a self-lubricating gearbox gear, comprising: a housing assembly 100 and a lubrication assembly 200 disposed within the housing assembly 100, wherein the housing assembly 100 includes a gearbox body 110 and a gear shaft assembly 120 disposed within the gearbox body 110.

[0026] The lubrication assembly 200 includes a mounting mechanism disposed at the bottom of the gearbox body 110, a lubrication mechanism connected to the mounting mechanism, and a filter mechanism disposed at the end of the lubrication mechanism. The lubrication mechanism includes a mounting bracket 210 mounted at the bottom of the gearbox body 110, a transmission gear 220 assembled on the mounting bracket 210 and meshing with the gear shaft assembly 120, a connecting rod 230 connected to the middle of the transmission gear 220, a screw 240 disposed at the middle of the connecting rod 230, a compression cylinder 250 connected to the mounting mechanism and located outside the screw 240, a connecting pipe 260 connected to the end of the compression cylinder 250, and a filter mechanism opened on the gearbox body 110 and connected to the gear shaft assembly 120. The upper oil flow channel 270 connected by the connecting pipe 260 and the nozzle 280 connected to the upper oil flow channel 270 and located at the top of the gearbox body 110, through the lubrication assembly 200, can drive the transmission gear 220 to rotate by the gear shaft assembly 120, thereby driving the screw 240 to rotate in the compression cylinder 250, so that the lubricating oil overflowing the compression cylinder 250 enters the compression cylinder 250 and is compressed and moved towards one end of the connecting pipe 260. In this way, the lubricating oil enters the upper oil flow channel 270 and flows upward, and then is sprayed out from the nozzle 280 to lubricate the gear shaft assembly 120 below. Compared with splash lubrication and oil pump lubrication, this solution is not only more thorough in lubrication, but also simpler and more convenient to use and maintain, and is easy to promote and use.

[0027] Furthermore, the mounting mechanism includes a mounting base 310 mounted on the bottom of the gearbox body 110, a filter cotton 320 embedded in the mounting base 310, a spring 330 disposed in the mounting base 310, a support rod 340 connected to the end of the spring 330, and a connecting block 350 fixed to the bottom of the compression cylinder 250 and sleeved with the support rod 340. The compression cylinder 250 can be fixed using the mounting base 310, the spring 330, and the support rod 340, and the connection and fixing position can be adaptively adjusted according to the installation height of the compression cylinder 250, making it highly practical.

[0028] Furthermore, the filtration mechanism includes a filter cylinder 360 fixed to the end of the connecting rod 230, a fixing block 370 fixed to the connecting rod 230 and located inside the filter cylinder 360, an insert rod 380 inserted into the middle of the fixing block 370, and vibrating balls 390 fixed to both ends of the insert rod 380. The filter cylinder 360 can be used to filter the lubricating oil entering the compression cylinder 250. At the same time, when the connecting rod 230 rotates, it will drive the vibrating balls 390 on the insert rod 380 to strike the filter cylinder 360, so that the filtered filter residue falls into the filter box 321, thereby realizing the collection of impurities in the lubricating oil and ensuring the effectiveness of the lubricating oil.

[0029] It should be noted that the filter cylinder 360 has an annular groove structure in the middle, which makes it easier for the vibrating ball 390 to clean the debris off the filter cylinder 360, making it highly practical.

[0030] On the other hand, the filter cotton 320 is provided with a filter box 321 located at the end of the compression cylinder 250, which can collect the impurities filtered down from the filter cylinder 360. The filter cotton 320 also plays the role of adsorbing impurities in the lubricating oil, thus ensuring that the lubricating oil has a longer service life.

[0031] Furthermore, the end of the compression cylinder 250 is provided with a limiting groove 251 for the filter cylinder 360 to be inserted, which facilitates the positioning of the filter cylinder 360 and makes it more stable.

[0032] It should be noted that the bottom of the gearbox body 110 is provided with an oil change hole 111 connected to the upper oil flow channel 270. The lubricating oil in the gearbox body 110 can be cleaned and replaced through the oil change hole 111, which is highly practical.

[0033] The working principle and usage process of this utility model are as follows: First, the gear shaft assembly 120 drives the transmission gear 220 to rotate, which in turn drives the screw 240 to rotate inside the compression cylinder 250. This allows the lubricating oil overflowing the compression cylinder 250 to enter the compression cylinder 250 and move towards one end of the connecting pipe 260. This causes the lubricating oil to enter the upper oil flow channel 270 and flow upwards. Then, it is sprayed out from the nozzle 280 to lubricate the gear shaft assembly 120 below. At the same time, the filter cylinder 360 filters the lubricating oil entering the compression cylinder 250. Meanwhile, when the connecting rod 230 rotates, it drives the vibrating ball 390 on the insertion rod 380 to strike the filter cylinder 360, causing the filtered filter residue to fall into the filter box 321, thus achieving the collection of impurities in the lubricating oil.

[0034] Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.
