Description

Technical Field

[0001] The utility model relates to the technical field of speed reducers, in particular to a speed reducer capable of automatic lubrication. Background Art

[0002] A reducer is a mechanical device used to reduce the speed of moving parts while increasing torque. It is usually composed of gears, bearings, and housings, and is widely used in various mechanical equipment. When lubricating the transmission gear components of a reducer, an appropriate amount of lubricating oil is usually added to the inside of the gearbox.

[0003] Patent number "CN211737975U" discloses a "self-lubricating reducer". This device can automatically inject the externally stored lubricating oil into the reducer through the squeezing of an external spring, so that the lubricating oil inside the reducer is always filled, avoiding gear wear caused by too little lubricating oil. At the same time, the amount of lubricating oil can be clearly known, which is convenient for adding. As the reducer lubricating oil is placed for a long time, material stratification will appear inside it, and some lubricating oil will also contain solid impurity precipitation particles. If this kind of lubricating oil is directly added to the gear box and used for a long time, it will directly affect the normal transmission of the gear set. However, the above device has not made any improvements to this problem, and the overall practical effect is poor. Utility Model Content

[0004] The purpose of this utility model is to solve the above-mentioned problems and propose an automatic lubricating reducer, which improves the existing reducer lubricating oil. The phenomenon of material stratification will occur inside the lubricating oil after being placed for a long time, and some lubricating oil will also contain solid impurity precipitation particles. If this kind of lubricating oil is directly added to the gear box and used for a long time, it will directly affect the normal transmission of the gear set.

[0005] A speed reducer capable of automatic lubrication comprises a support base, a speed reducer body and an oil storage barrel: the speed reducer body is mounted on the top outer wall of the support base, and the oil storage barrel is provided on the top outer wall of the support base; a filling and lubricating mechanism is provided on the side of the speed reducer body; a filtering and purifying mechanism is provided on the side of the filling and lubricating mechanism; and a homogenizing mixing mechanism is provided inside the oil storage barrel;

[0006] The lubrication filling mechanism includes an oil pump, a first oil filling pipe, a second oil filling pipe, a third oil filling pipe and a one-way control valve. The oil pump is installed on the inner wall of the bottom end of the oil storage barrel. The oil outlet end of the oil pump is connected to one end of the first oil filling pipe. The side of the first oil filling pipe is provided with a second oil filling pipe, and the side of the second oil filling pipe is provided with a third oil filling pipe. The outer wall of the bottom end of the third oil filling pipe at the oil outlet end position is connected and installed with the outer wall of the top end of the reducer body at the gear box position. A one-way control valve is provided on the outside of the first oil filling pipe.

[0007] Preferably, the filtering and purification mechanism includes a limiting filter, a first flange assembly and a second flange assembly, and the second oil filling pipe is connected to the inner wall of the side near the position of the third oil filling pipe with a limiting filter, the first oil filling pipe and the second oil filling pipe are connected and installed through the first flange assembly, and the second oil filling pipe and the third oil filling pipe are connected and installed through the second flange assembly.

[0008] Preferably, the limiting filter is configured as a porous mesh plate structure.

[0009] Preferably, the homogeneous mixing mechanism includes a driving motor, a transmission shaft, a first stirring blade and a second stirring blade. The top outer wall of the oil storage barrel is provided with a driving motor, the output end of the driving motor is connected to the top outer wall of the transmission shaft, and the first stirring blade and the second stirring blade are provided at staggered positions outside the transmission shaft located inside the oil storage barrel.

[0010] Preferably, the first stirring blade is configured as a spiral structure, and the second stirring blade is configured as a strip plate structure.

[0011] Preferably, a drain pipe is installed on the side outer wall of the reducer body located near the bottom end of the gear box, and a control valve is provided on the outside of the drain pipe.

[0012] Preferably, an oil filling pipe is installed on the top outer wall of the oil storage barrel, and a window is provided on the side outer wall of the oil storage barrel.

[0013] The beneficial effects of the utility model are:

[0014] 1. When the automatic lubricating reducer is in use, a limit filter is added to the lubricating oil filling pipe. When the lubricating oil is added, the solid impurity particles entrained in the lubricating oil can be automatically filtered out through the isolation and filtration effect of the limit filter. This ensures that the lubricating oil entering the gear box is clean, which provides a guarantee for the lubrication effect of the subsequent gear set transmission. The oil filling pipe equipped with the limit filter is further set to a detachable design through the mechanism component, which greatly facilitates the cleaning process of solid impurity particles in the subsequent pipeline. The overall structural design is simple and has good practical effect.

[0015] 2. When the automatic lubricating reducer is in use, a mechanism component is set inside the oil storage barrel to synchronously drive the rotation of two groups of stirring blades of different shapes. The first stirring blade is set to a spiral structure so that when it rotates, it can achieve a longitudinal mixing effect on the lubricating oil inside the oil storage barrel by conveying it in a longitudinal trajectory. The second stirring blade is set to a strip plate structure so that when it rotates, it can achieve a transverse mixing effect on the lubricating oil inside the oil storage barrel. The synchronous mixing in the transverse and longitudinal directions can quickly complete the homogenization process of the lubricating oil inside the oil storage barrel, thereby ensuring the uniform mixing of the lubricating oil material components and the subsequent lubricating effect of the lubricating oil on the gear assembly. The overall structural design is ingenious and has good practical effect. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] When implementing: Figure 1-5As shown, a speed reducer with automatic lubrication includes a support base 1, a speed reducer body 2 and an oil storage barrel 3: the speed reducer body 2 is mounted on the top outer wall of the support base 1, and the oil storage barrel 3 is provided on the top outer wall of the support base 1, a filling and lubricating mechanism 4 is provided on the side of the speed reducer body 2, a filtering and purifying mechanism 5 is provided on the side of the filling and lubricating mechanism 4, and a homogenizing mixing mechanism 6 is provided inside the oil storage barrel 3;

[0024] The lubricating mechanism 4 includes an oil pump 41, a first oil filling pipe 42, a second oil filling pipe 43, a third oil filling pipe 44 and a one-way control valve 45. The oil pump 41 is installed on the inner wall of the bottom end of the oil storage barrel 3, and the oil outlet end of the oil pump 41 is connected to one end of the first oil filling pipe 42. The side of the first oil filling pipe 42 is provided with a second oil filling pipe 43, and the side of the second oil filling pipe 43 is provided with a third oil filling pipe 44. The outer wall of the bottom end of the third oil filling pipe 44 at the oil outlet position is connected and installed with the top outer wall of the reducer body 2 at the gear box position. A one-way control valve 45 is provided on the outside of the first oil filling pipe 42. When the lubricating oil in the built-in gear box of the reducer body 2 is completely discharged and new lubricating oil needs to be added, it is only necessary to turn on the oil pump 41. When the oil pump 41 is turned on, it will automatically fill the oil storage barrel 3 The internal lubricating oil is drawn into the first oil filling pipe 42, and then transported to the second oil filling pipe 43 through the drainage of the first oil filling pipe 42, and finally transported to the interior of the gear box through the drainage of the second oil filling pipe 43. After the appropriate amount of lubricating oil is transported, the oil pump 41 can be closed. The setting of the one-way control valve 45 here ensures that the lubricating oil will not flow back into the oil storage barrel 3 after being sent out through the first oil filling pipe 42.

[0025] The filtering and purification mechanism 5 includes a limiting filter 51, a first flange assembly 52 and a second flange assembly 53. The limiting filter 51 is connected to the inner wall of the side of the second oil filling pipe 43 near the third oil filling pipe 44. The first oil filling pipe 42 and the second oil filling pipe 43 are connected and installed through the first flange assembly 52, and the second oil filling pipe 43 and the third oil filling pipe 44 are connected and installed through the second flange assembly 53. The setting of the limiting filter 51 here enables some solid impurity particles entrained in the lubricating oil when it is transported through the first oil filling pipe 42 to be automatically isolated on the side of the limiting filter 51, thereby ensuring the cleanliness of the lubricating oil entering the device on the basis of filtering and removing impurities. When the second oil filling pipe 43 needs to be removed from the inside of the device to clean the solid impurity particles accumulated inside it, it is only necessary to remove the first flange assembly 52 and the second flange assembly 53 installed on both sides of the second oil filling pipe 43 in turn according to the existing operating technical means to remove the second oil filling pipe 43 as a whole. After cleaning, the installation is similar.

[0026] The limiting filter 51 is configured as a porous mesh plate structure; with this design, the limiting filter 51 can conveniently filter out solid impurity particles entrained in the lubricating oil.

[0027] The homogenizing mixing mechanism 6 includes a driving motor 61, a transmission shaft 62, a first stirring blade 63 and a second stirring blade 64. The driving motor 61 is provided on the top outer wall of the oil storage barrel 3, and the output end of the driving motor 61 is connected to the top outer wall of the transmission shaft 62. The first stirring blade 63 and the second stirring blade 64 are provided at staggered positions outside the transmission shaft 62 located inside the oil storage barrel 3; when the lubricating oil has been placed for too long and needs to be homogenized when used again, it is only necessary to turn on the driving motor 61. When the driving motor 61 is turned on, it will automatically drive the transmission shaft 62 to rotate and then drive the first stirring blade 63 and the second stirring blade 64 to rotate synchronously.

[0028] The first stirring blade 63 is set to a spiral structure, and the second stirring blade 64 is set to a strip plate structure; here, the first stirring blade 63 is set to a spiral structure so that when it rotates, it can achieve a longitudinal mixing effect on the lubricating oil inside the oil storage barrel 3 by conveying it in a longitudinal trajectory, and the second stirring blade 64 is set to a strip plate structure so that when it rotates, it can achieve a transverse mixing effect on the lubricating oil inside the oil storage barrel 3, and then the synchronous mixing in the transverse and longitudinal directions can quickly complete the homogenization process of the lubricating oil inside the oil storage barrel 3.

[0029] The reducer body 2 is located on the side outer wall near the bottom of the gear box and is connected to a drain pipe, and a control valve is provided on the outside of the drain pipe; the drain pipe here is used to discharge the old lubricating oil inside the gear box, and the control valve is used to control the opening and closing of the drain pipe.

[0030] An oil filling pipe is installed on the top outer wall of the oil storage barrel 3, and a window is provided on the side outer wall of the oil storage barrel 3; the oil filling pipe is provided here for adding lubricating oil to the inside of the oil storage barrel 3, and the window is provided for convenient observation of the remaining lubricating oil inside the oil storage barrel 3 to determine whether lubricating oil needs to be added thereto.

[0031] When the present invention is in use, if the lubricating oil has been stored for too long and needs to be homogenized before being used again, it is only necessary to turn on the driving motor 61. When the driving motor 61 is turned on, it will automatically drive the transmission shaft 62 to rotate, thereby driving the first stirring blade 63 and the second stirring blade 64 to rotate synchronously. Here, the first stirring blade 63 is set as a spiral structure so that when it rotates, it can achieve a longitudinal mixing effect on the lubricating oil inside the oil storage barrel 3 by conveying it in a longitudinal trajectory. The second stirring blade 64 is set as a strip plate structure so that when it rotates, it can achieve a transverse mixing effect on the lubricating oil inside the oil storage barrel 3. Then, the synchronous mixing in the transverse and longitudinal directions can quickly complete the homogenization process of the lubricating oil inside the oil storage barrel 3.

[0032] When the lubricating oil in the gearbox built into the reducer body 2 is completely drained and new lubricating oil needs to be added, it is only necessary to start the oil pump 41. When the oil pump 41 is turned on, the lubricating oil in the oil storage barrel 3 is automatically pumped into the first oil filling pipe 42, and then delivered to the second oil filling pipe 43 through the drainage of the first oil filling pipe 42. Finally, it is delivered to the interior of the gearbox through the drainage of the second oil filling pipe 43. After the appropriate amount of lubricating oil is delivered, the oil pump 41 can be turned off. The one-way control valve 45 is set here to prevent the lubricating oil from flowing back into the oil storage barrel 3 after being delivered through the first oil filling pipe 42.

[0033] The setting of the limiting filter 51 here ensures that some of the solid impurity particles entrained in the lubricating oil when it is transported through the first oil filling pipe 42 will be automatically isolated on the side of the limiting filter 51, thereby ensuring the cleanliness of the lubricating oil entering the device on the basis of filtering and removing impurities. When the second oil filling pipe 43 needs to be removed from the inside of the device to clean the solid impurity particles accumulated inside it, it is only necessary to remove the first flange assembly 52 and the second flange assembly 53 installed on both sides of the second oil filling pipe 43 in turn according to existing operating technical means to remove the second oil filling pipe 43 as a whole. The same installation can be performed after cleaning.

[0034] It is noted here that the above-mentioned drive motor 61 can be powered by existing operating technical means, whether it is powered by a power supply component or an external wire, which belongs to existing conventional operating technical means and will not be described in detail here.

[0035] In addition, it should be understood that although this specification is described in terms of implementation methods, not every implementation method contains only one independent technical solution. This narrative method of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other implementation methods that can be understood by those skilled in the art.
