Description

Technical Field

[0001] The utility model relates to the technical field of reducers, in particular to a reducer gear box assembly with a lubrication mechanism. Background Art

[0002] The reducer gearbox refers to the gear reduction box. The gear reduction box works according to the principle that the prime mover is connected to the reduction box, and the reduction box is then connected to the working machine. It is a power transmission device. The commonly used prime movers are: steam engine, electric motor, hydraulic motor, gas turbine, internal combustion engine, etc. The prime mover is a machine that provides power. When there is a reduction transmission, the prime mover provides high-speed, low-torque power. Conversely, when there is a speed increase transmission, the prime mover provides low-speed, high-torque power. In mechanical transmission, the gear reduction box needs to drive its working object-the working machine to achieve the predetermined purpose.

The utility model relates to the technical field of gear reducers. The gear reducer with an overload protection component can lubricate the gear mechanism and export excess lubricating oil through the provision of a lubricating mechanism, thereby avoiding excessive lubricating oil affecting the operation of the gear reducer, thereby making the operation of the gear reducer more stable and improving the service life of the gear reducer.

[0004] However, in the implementation of relevant technologies, it was found that the above-mentioned design of the gear reducer with an overload protection component has the following problems: the excess lubricating oil is collected by the provided oil leakage pipe and the collection box for use next time.

Therefore, the present utility model is not limited by the specific embodiments disclosed below.

[0024] Secondly, the so-called "one embodiment" or "embodiment" herein refers to a specific feature, structure, or characteristic that can be included in at least one implementation manner of the present utility model. The "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment that is mutually exclusive with other embodiments.

[0025] Furthermore, the present utility model is described in detail in conjunction with schematic diagrams. When detailing the embodiments of the present utility model, for the convenience of explanation, the cross-sectional views showing the device structure will be enlarged locally out of the general proportion, and the schematic diagrams are only examples and should not limit the scope of protection of the present utility model herein. In addition, in actual production, three-dimensional spatial dimensions including length, width, and depth should be included.

[0026] Refer to Figures 1 - 3 , which is an embodiment of the present utility model, and provides a speed reducer gearbox assembly with a lubrication mechanism, including a lubrication unit 100 and a return unit 200.

[0027] Among them, the lubrication unit 100 includes a gearbox main body 101 and a diversion frame 102 that is installed in a matching manner with the gearbox main body 101. A collection box 103 is fixedly installed at the bottom end of the diversion frame 102. A fuel tank 105 is fixedly installed at the top end of the gearbox main body 101, and a sealing cover 106 is provided at the top end of the fuel tank 105. The gear structure inside the gearbox main body 101 is a prior art and has little connection with the technical problem, so it will not be elaborated here. Open the sealing cover 106 and deliver lubricating oil into the fuel tank 105. The lubricating oil drops on the gears inside the gearbox main body 101 to achieve the lubrication effect, and then the lubricating oil drops onto the diversion frame 102 and is collected into the collection box 103;

[0028] The return unit 200 includes a mounting base 201 fixedly installed on one side of the collection tank 103. At the top of the mounting base 201, an oil pump 202 is fixedly installed. The inlet end of the oil pump 202 is fixedly installed with an inlet pipe 203, and the inlet pipe 203 penetrates through the inner wall of the collection tank 103. The outlet end of the oil pump 202 is fixedly installed with an outlet pipe 204, and the outlet pipe 204 penetrates through the inner wall of the fuel tank 105. A chute 207 is provided on one side of the fuel tank 105, and an installation frame 205 is slidably connected to the inner cavity of the chute 207. A handle 208 is fixedly installed on one side of the installation frame 205. A filter screen 206 is installed in the inner cavity of the installation frame 205, and the filter screen 206 is located below the outlet pipe 204. A limiting structure is provided on one side of the fuel tank 105. When the oil pump 202 is started, the oil pump 202 extracts the collected lubricating oil from the collection tank 103 through the inlet pipe 203. Subsequently, this lubricating oil is conveyed into the fuel tank 105 through the outlet pipe 204. In the fuel tank 105, the lubricating oil will pass through the filter screen 206 for filtration to remove impurities and ensure the purity of the oil quality. The filtered lubricating oil is guided to the gear surface again to achieve continuous dripping lubrication, which not only significantly improves the lubrication effect of the gear and extends the service life of the equipment, but also solves the problems of cumbersome, time-consuming, laborious, cost increase and resource waste caused by manual extraction and re-infusion of lubricating oil in the traditional method. Then, the installation frame 205 can be pulled out of the chute 207 through the handle 208 to clean and replace the filter screen 206.

[0029] The limiting structure includes movable cavities 209 symmetrically opened on one side of the fuel tank 105. Slide rods 210 are fixedly installed in the two groups of movable cavities 209. An L-shaped plate 212 is vertically slidably connected to the outer surfaces of the two groups of slide rods 210, and the inner walls of the two groups of L-shaped plates 212 are attached to the surface of the installation frame 205. When the two groups of L-shaped plates 212 are moved upward, the L-shaped plates 212 are no longer attached to the installation frame 205, and the limitation of the installation frame 205 is cancelled. Then, the filter screen 206 can be pulled out of the inner cavity of the fuel tank 105 to clean and replace it.

[0030] A connecting strip 213 is fixedly installed on the opposite surfaces of the two groups of L-shaped plates 212, and the connecting strip 213 is located above the handle 208. The two groups of L-shaped plates 212 are simultaneously driven to move upward through the connecting strip 213.

[0031] A telescopic spring 211 is sleeved on the outer surfaces of two groups of sliding rods 210, and two ends of the telescopic spring 211 are fixedly connected to the top end of the L-shaped plate 212 and the inner wall of the movable cavity 209 respectively. When the L-shaped plate 212 moves upward, the L-shaped plate 212 will squeeze the telescopic spring 211. When the movement of the L-shaped plate 212 is cancelled, the telescopic spring 211 rebounds and drives the L-shaped plate 212 to move downward. The inner wall of the L-shaped plate 212 fits against the outer wall of the mounting frame 205 to limit the mounting frame 205, facilitating the installation and disassembly of the filter screen 206.

[0032] A drain pipe 107 is fixedly installed at the bottom end of the inner cavity of the fuel tank 105, and the drain pipe 107 penetrates through the top end of the gearbox main body 101. A sub-drain pipe 108 is fixedly installed at the bottom end of the drain pipe 107, and a number of uniformly distributed oil outlet holes are formed at the bottom end of the sub-drain pipe 108. The lubricating oil in the fuel tank 105 enters the sub-drain pipe 108 through the drain pipe 107, and the lubricating oil in the sub-drain pipe 108 falls onto the gears that need to be lubricated through the oil outlet holes to achieve the lubrication effect.

[0033] A support frame 104 is arranged on the outer surface of the gearbox main body 101, and legs are fixedly installed at the four corners of the bottom end of the support frame 104. The support frame 104 and the legs ensure the stability of the gearbox main body 101.

[0034] During use, open the sealing cover 106 and deliver lubricating oil into the fuel tank 105. The lubricating oil in the fuel tank 105 enters the distribution pipe 108 through the guide pipe 107. The lubricating oil in the distribution pipe 108 falls onto the gears that need to be lubricated through the oil outlet holes, achieving the lubrication effect. Then, the excess lubricating oil on the gears drips onto the diversion frame 102 and is collected in the collection box 103. Start the oil pump 202. The oil pump 202 extracts the collected lubricating oil from the collection box 103 through the inlet pipe 203. Subsequently, this lubricating oil is delivered into the fuel tank 105 through the outlet pipe 204. In the fuel tank 105, the lubricating oil will be filtered through the filter screen 206 to remove impurities and ensure the purity of the oil quality. The filtered lubricating oil is again guided to the gear surface to achieve continuous dripping lubrication, which not only significantly improves the lubrication effect of the gears, extends the service life of the equipment, but also solves the problems of cumbersome, time-consuming, laborious, increased cost, and resource waste caused by manually extracting and refilling lubricating oil in the traditional method. Cancel the limit on the installation frame 205 by the limit structure, and then the installation frame 205 can be pulled out of the sliding groove 207 through the handle 208 to clean and replace the filter screen 206. By means of the connecting strip 213, the two groups of L-shaped plates 212 are simultaneously driven to move upward. The L-shaped plates 212 no longer fit the installation frame 205, and the limit on the installation frame 205 is cancelled. Then, the filter screen 206 can be pulled out from the inner cavity of the fuel tank 105. When the L-shaped plates 212 move upward, they will squeeze the telescopic springs 211. When the movement of the L-shaped plates 212 is cancelled, the telescopic springs 211 rebound and drive the L-shaped plates 212 to move downward. The inner walls of the L-shaped plates 212 fit the outer walls of the installation frame 205 to limit the installation frame 205, which is convenient for installing and disassembling the filter screen 206.

[0035] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not restrictive. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the spirit and scope of the technical solutions of the present invention, and they should all be covered within the scope of the claims of the present invention.
