[0003] Publication No. CN214578774U discloses an electric transmission gear reducer, which drives the movable rod to move up and down by rotating the knob to adjust the position of the plug plate in the oil storage box, thereby adjusting the oil discharge of the lubricating oil in the oil storage box. When not in use, the oil discharge state is maintained, and a small amount of lubricating oil or a large amount of lubricating oil can be discharged according to actual conditions. Users can make adjustments according to actual conditions to fully meet user needs; and effectively solve the trouble caused by disassembling the shell, but the patent still has the following problems in actual use:

[0004] Although this electric transmission gear reducer drives the movable rod to move up and down by rotating the knob to adjust the position of the plug plate in the oil storage box, thereby adjusting the oil discharge of the lubricating oil in the oil storage box and keeping it in a non-discharging state when not in use, it cannot achieve automatic addition of lubricating oil and requires human judgment on whether addition is needed. However, there is a certain deviation in the judgment results of each person, which can easily increase the wear of the gears and reduce the service life of the reducer.

[0005] A speed reducer provided with an oil storage tank is proposed to solve the above-mentioned problems. Utility Model Content

[0006] The purpose of the utility model is to provide a reducer with an oil storage tank to solve the problem proposed in the above background technology that the position of the plug plate in the oil storage box is adjusted by rotating the knob to drive the movable rod to move up and down, thereby adjusting the oil discharge of the lubricating oil in the oil storage box to keep the oil discharge state when not in use, but the automatic addition of lubricating oil cannot be achieved, and it is necessary to rely on human judgment whether it needs to be added. There is a certain deviation in the judgment result of each person, which is easy to increase the wear of the gears and reduce the service life of the reducer.

[0007] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a reducer provided with an oil storage tank, comprising a lubrication mechanism, and a guide tube installed inside the lubrication mechanism;

[0008] Also includes:

[0009] The lubrication mechanism comprises a reducer body, and an oil storage groove is provided at the center of the top of the reducer body;

[0010] Wherein, a movable plate is slidably connected inside the oil storage tank, an oil-absorbing sponge is fixedly connected to the top of the movable plate, and a support column is fixedly connected to the center of the bottom of the movable plate;

[0011] Wherein, a sleeve is sleeved on the outer side of one end of the support column away from the movable plate, and the bottom of the sleeve is fixedly connected to the reducer body.

[0012] Preferably, a first spring is fixedly connected to the bottom side of the sleeve, the top end of the first spring is fit-connected to the support column, damping particles are fixedly connected to the top side of the sleeve, and the inside of the damping particles is interlaced and connected to the support column.

[0013] Preferably, the reducer body is fixedly connected to the guide tube just above the oil storage tank, and a second spring is fixedly connected to one side inside the guide tube.

[0014] Preferably, one end of the second spring is fixedly connected to a movable block, and an outer side of the movable block away from the one end of the second spring is snap-connected to a sealing ring.

[0015] Preferably, the outer side of the sealing ring is closely connected to the guide tube, and a through hole is formed at one end of the movable block close to the sealing ring.

[0016] Preferably, a bolt is threadedly connected at the center position of the bottom of the reducer body, and one end of the bolt is fixedly connected to a third spring.

[0017] Preferably, one end of the third spring away from the bolt is fixedly connected to a sealing block, and the outer side of the sealing block is slidably connected to the reducer body.

[0018] Compared with the prior art, the beneficial effect of the utility model is that the reducer provided with an oil storage tank can not only realize the automatic addition of lubricating oil by setting a lubricating mechanism, but also can avoid the leakage of lubricating oil. The specific contents are as follows:

[0019] By setting up the lubrication mechanism, not only can the automatic addition of lubricating oil be realized, but also the leakage of lubricating oil can be avoided. When the lubricating oil in the reducer body is insufficient, the wear between the internal gears increases, thereby increasing the vibration frequency of the reducer body, so that the movable plate in the oil storage tank moves up and down. By utilizing the cooperation between the oil storage tank and the movable plate, the lubricating oil in the oil-absorbing sponge can be dripped from both sides onto the gears, thereby realizing the automatic addition of lubricating oil and restoring the reducer body to a normal operating state. At the same time, the restoring force of the first spring is utilized to drive the movable plate to move upward and reset, thereby avoiding the dripping of lubricating oil. During the upward movement of the support column, it contacts the damping particles, thereby absorbing the rebound force of the first spring, which can improve the stability of the upward movement of the movable plate. Through the cooperation between the second spring and the movable block, the one-way flow of lubricating oil in the guide tube can be realized, so that the lubricating oil can only enter the oil storage tank from the outside, thereby avoiding the leakage of lubricating oil. By utilizing the cooperation between the bolt and the sealing block, the lubricating oil at the bottom of the reducer body can be easily collected, and the lubricating oil can be reused to reduce costs.

During the upward movement of the support column 105, it contacts with the damping particles 108, thereby absorbing the rebound force of the first spring 107, which can improve the stability of the upward movement of the movable plate 103;

[0029] The reducer body 101 is fixedly connected to the guide tube 109 just above the oil storage tank 102, and a second spring 110 is fixedly connected to one side of the guide tube 109. A movable block 111 is fixedly connected to one end of the second spring 110. A sealing ring 112 is engaged and connected to the outer side of the movable block 111 away from one end of the second spring 110. The outer side of the sealing ring 112 is closely connected to the guide tube 109. A through hole 113 is provided at one end of the movable block 111 close to the sealing ring 112. The cooperation between the second spring 110 and the movable block 111 can realize one-way flow of lubricating oil in the guide tube 109, so that the lubricating oil can only enter the oil storage tank 102 from the outside, thereby avoiding leakage of the lubricating oil.

[0032] Secondly, when the lubricating oil in the reducer body 101 is insufficient, the wear between its internal gears increases, which leads to an increase in the vibration frequency of the reducer body 101, so that the movable plate 103 in the oil storage tank 102 moves up and down, and the cooperation between the oil storage tank 102 and the movable plate 103 can make the lubricating oil in the oil-absorbing sponge 104 drip from both sides onto the gears, thereby realizing automatic addition of lubricating oil and restoring the reducer body 101 to a normal operating state, and at the same time, the restoring force of the first spring 107 is used to drive the movable plate 103 to move upward and reset to avoid dripping of lubricating oil. During the upward movement of the support column 105, it contacts the damping particles 108, thereby absorbing the rebound force of the first spring 107, which can improve the stability of the movable plate 103 moving upward, and finally, the cooperation between the bolt 114 and the sealing block 116 can facilitate the collection of the lubricating oil at the bottom of the reducer body 101, so as to achieve repeated use of the lubricating oil and reduce costs.
