Description

Technical Field

[0001] The utility model relates to the technical field of gear reduction motors, and particularly relates to a gear reduction motor convenient for replacing cooling oil. Background Art

[0002] A gear reduction motor refers to a combination of a gear reduction box and a motor. This combination is usually also called a gearbox motor or a reduction motor. The cooling oil of the gear reduction motor (usually called gear oil) can not only act as a protective film on the surface of the parts of the gear reduction motor, effectively reducing its wear and thus delaying the service life of the gear reducer, but also reduce its transmission noise and vibration. In addition, proper lubrication of the gear reduction motor is also a kind of maintenance for it, which has the effect of preventing the friction parts from rusting.

[0003] After the gear reduction motor runs at high speed for a long time, the cooling oil will become thick and may also carry impurities. Therefore, during the use of the gear reduction motor, adding and replacing the cooling oil is an essential process. Currently, when replacing the cooling oil, the cooling oil inside is drained by opening the oil plug at the bottom end outside the gear reduction motor, and then new cooling oil is injected through the oil plug at the top end outside the gear reduction motor. However, since a large amount of impurities are likely to accumulate at the bottom end inside the gear reduction motor, simply replacing the cooling oil is difficult to completely discharge all the impurities. Therefore, it is necessary to open the gear reduction motor to clean the impurities. The outer side of the housing of the gear reduction motor is fixedly connected by multiple groups of bolts, making its disassembly too cumbersome and resulting in low efficiency of replacing the cooling oil.

[0004] Therefore, it is particularly important to urgently design a gear reduction motor convenient for replacing cooling oil to solve the above defects. Summary of the Utility Model

[0005] In view of the deficiencies of the prior art, the utility model designs a gear reduction motor convenient for replacing cooling oil, which aims to solve the technical problem that the disassembly of the gear reduction motor is too cumbersome when replacing the cooling oil in the prior art, resulting in low efficiency of replacing the cooling oil.

[0006] To achieve the above object, the utility model provides the following technical solutions:

[0007] A gear reduction motor convenient for replacing cooling oil includes a motor and a gearbox. The output end of the motor is fixedly connected to the input shaft of the gearbox. A large gear is rotatably connected inside the gearbox, and the large gear meshes with the input shaft of the gearbox. An oil change groove is opened at the bottom of the gearbox, a cleaning bottom plate is fixedly installed inside the oil change groove, fixing mechanisms are installed at both the front and rear ends of the cleaning bottom plate inside the gearbox, an oil filling plug is threadedly connected to the top of the gearbox, and a filter oil tank is fixedly installed on the front of the gearbox.

[0008] As a preferred solution of the present utility model, a magnetic rod is fixedly connected to one side of the cleaning bottom plate inside the gearbox, and a first sealing ring is sleeved outside the cleaning bottom plate and inside the oil change groove.

[0009] As a preferred solution of the present utility model, the fixing mechanism includes movable grooves opened inside the gearbox and located at the front and rear ends of the cleaning bottom plate. Fixed blocks are slidably connected to the inner sides of the two movable grooves. Springs are fixedly connected to one ends of the two fixed blocks located inside the movable grooves. Operating blocks are fixedly connected to the bottoms of the two fixed blocks and extend to the outside of the gearbox.

[0010] As a preferred solution of the present utility model, fixing inclined grooves are opened on the opposite sides of the two fixed blocks and the cleaning bottom plate, and a moving groove is opened at a position corresponding to the operating block at the bottom of the gearbox.

[0011] As a preferred solution of the present utility model, an oil filling channel is opened inside the oil filling plug, and a second sealing ring is sleeved outside the oil filling plug.

[0012] As a preferred solution of the present utility model, oil through grooves are opened at the upper and lower ends inside the gearbox and inside the oil filter tank.

The magnetic rod adsorbs and aggregates metal debris together. When disassembling the cleaning bottom plate for oil change, it is convenient to clean out the metal debris together. When the cooling oil needs to be replaced, the fixing of the cleaning bottom plate can be quickly released through the fixing mechanism. After the cleaning bottom plate is released from the fixing, it automatically falls out of the oil change groove, which is convenient to quickly discharge the cooling oil and the impurities accumulated at the bottom end inside the gearbox, thereby improving the convenience of oil change and the replacement efficiency of the cooling oil.

[0016] 2. In the present utility model, through the design of the filter oil tank, when the gearbox is working normally, when the cooling oil enters the filter oil tank, impurities in the cooling oil can be filtered when passing through the filter cotton inside the filter frame, and then flow back into the inside of the gearbox through the through holes inside the partition plate.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0023] The technical solutions in the embodiments of the present utility model will be clearly and completely described below in conjunction with the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0024] Embodiment:

[0025] Please refer to Figures 1 - 5 , the present utility model provides a technical solution:

[0026] A gear reduction motor facilitating the replacement of cooling oil, comprising a motor 1 and a gearbox 2. The output end of the motor 1 is fixedly connected to the input shaft 3 of the gearbox 2. A large gear 4 is rotatably connected inside the gearbox 2, and the large gear 4 meshes with the input shaft 3 of the gearbox 2. An oil change groove 5 is formed at the bottom of the gearbox 2, and a cleaning bottom plate 6 is fixedly installed inside the oil change groove 5. Fixing mechanisms 7 are installed at both the front and rear ends of the cleaning bottom plate 6 inside the gearbox 2. An oil filling plug 8 is threadedly connected to the top of the gearbox 2, and a filter oil tank 9 is fixedly installed on the front surface of the gearbox 2.

[0027] First, a magnetic rod 601 is fixedly connected to one side of the cleaning bottom plate 6 inside the gearbox 2. A first sealing ring 602 is sleeved outside the cleaning bottom plate 6 and inside the oil change groove 5. As the input shaft 3 and the large gear 4 work for a long time, they will be worn, and the worn metal debris will circulate inside the gearbox 2 together with the cooling oil, thus exacerbating the internal wear of the gearbox 2 and reducing the service life of the gearbox 2. When the cleaning bottom plate 6 is closed, the magnetic rod 601 adsorbs and aggregates the metal debris together. When the cleaning bottom plate 6 is disassembled for oil change, it is convenient to clean out the metal debris together. At the same time, when the cleaning bottom plate 6 is closed, the first sealing ring 602 ensures the sealing between the cleaning bottom plate 6 and the gearbox 2.

[0028] Then, the fixing mechanism 7 includes movable grooves 701 formed inside the gearbox 2 at both the front and rear ends of the cleaning bottom plate 6. Fixed blocks 702 are slidably connected to the inner sides of the two groups of movable grooves 701. Springs 703 are fixedly connected to one ends of the two groups of fixed blocks 702 located inside the movable grooves 701. Operating blocks 704 are fixedly connected to the bottoms of the two groups of fixed blocks 702 and extend outside the gearbox 2. Fixed inclined grooves 705 are formed on the opposite sides of the two groups of fixed blocks 702 and the cleaning bottom plate 6. Moving grooves 706 are formed at the positions corresponding to the operating blocks 704 at the bottom of the gearbox 2. When the cleaning bottom plate 6 is closed, the fixed blocks 702 are pushed outward of the movable grooves 701 under the action of the springs 703, and the fixed inclined grooves 705 on the opposite sides of the fixed blocks 702 and the cleaning bottom plate 6 are fitted, so that the fixed blocks 702 always have a force to push the cleaning bottom plate 6 upward, thus firmly fixing the cleaning bottom plate 6 to avoid the risk of oil leakage. At the same time, when the cooling oil needs to be replaced, the fixed blocks 702 are slid by the operating blocks 704, so that the fixed blocks 702 lock the inner sides of the movable grooves 701, and the fixing of the cleaning bottom plate 6 can be quickly released. After the cleaning bottom plate 6 is released from the fixing, it automatically falls out of the oil change groove 5, which is convenient to quickly discharge the cooling oil and the impurities accumulated at the bottom end inside the gearbox 2, thereby improving the convenience of oil change and the replacement efficiency of the cooling oil.

[0029] Further, an oil filling channel 801 is provided inside the oil filling plug 8, and a second sealing ring 802 is sleeved outside the oil filling plug 8. After the cooling oil inside the gearbox 2 is discharged, the cleaning bottom plate 6 is closed, and then new cooling oil is added through the oil filling channel 801 inside the oil filling plug 8. Here, it should be noted that a one-way valve is also installed inside the oil filling channel 801, which can cooperate with the second sealing ring 802 to avoid oil leakage problems while facilitating oil filling.

[0030] Secondly, oil through grooves 901 are provided at both the upper and lower ends inside the gearbox 2 and on the inner side of the oil filter tank 9. A partition plate 902 is fixedly connected inside the gearbox 2. A filter frame 903 is inserted into the partition plate 902. A filter cotton 904 is fixedly installed inside the filter frame 903. A through hole 905 is provided at the front end of the partition plate 902. When the gearbox 2 is working normally, the cooling oil inside can be introduced into the oil filter tank 9 through the oil through grooves 901. When the cooling oil enters the oil filter tank 9, the impurities in the cooling oil can be filtered when passing through the filter cotton 904 inside the filter frame 903, and then flow back into the inside of the gearbox 2 through the through hole 905 inside the partition plate 902. Thus, by increasing the service life of the coolant, the number of oil changes is reduced, and the convenience of maintenance is improved.

[0031] Finally, a transparent observation window 906 is installed on the left side of the oil filter tank 9. A positioning plug 907 is slidably connected to the outside of the oil filter tank 9 and on the top of the filter frame 903. When the gearbox 2 is working, the cooling oil entering the inside of the oil filter tank 9 can be observed through the transparent observation window 906 to judge in advance whether the cooling oil needs to be replaced, so as to replace the cooling oil in time to ensure the normal operation of the gearbox 2. When the cooling oil needs to be replaced, the corresponding filter cotton 904 also needs to be replaced. At this time, the positioning plug 907 is pulled out, and the filter frame 903 can be pulled out from the inside of the oil filter tank 9, thus facilitating the replacement of the filter cotton 904 inside.

[0032] In this embodiment, the implementation scenario is specifically as follows: When the cleaning bottom plate 6 is closed, under the action of the spring 703, the fixed block 702 is pushed outward to the active groove 701, and the fixed inclined groove 705 of the fixed block 702 is attached to the cleaning bottom plate 6, so that the fixed block 702 always has a force to push the cleaning bottom plate 6 upward, thereby firmly fixing the cleaning bottom plate 6 to avoid the risk of oil leakage. The magnetic rod 601 is used to adsorb and gather metal debris together. When disassembling the cleaning bottom plate 6 for oil change, it is convenient to clean out the metal debris together. When the cooling oil needs to be replaced, the fixed block 702 is slid by the operation block 704, so that the fixed block 702 locks the inner side of the active groove 701, and the fixing of the cleaning bottom plate 6 can be quickly released. After the fixing of the cleaning bottom plate 6 is released, it automatically falls out of the inside of the oil change tank 5, which is convenient to quickly discharge the cooling oil and the impurities accumulated at the bottom end inside the gearbox 2 together. After the cooling oil inside the gearbox 2 is discharged, the cleaning bottom plate 6 is closed, and then new cooling oil is added through the oil filling channel 801 inside the oil filling plug 8. When the gearbox 2 is working normally, the internal cooling oil can be introduced into the oil filter tank 9 through the oil passage 901. When the cooling oil enters the oil filter tank 9, the impurities in the cooling oil can be filtered when passing through the filter cotton 904 inside the filter frame 903, and then flow back into the inside of the gearbox 2 through the through hole 905 inside the partition plate 902. The whole operation process is simple and convenient. Compared with the existing gear reduction motor, the present utility model can improve the convenience of replacing the cooling oil of the gear reduction motor through the design, and at the same time can reduce the number of oil changes and improve the maintenance convenience of the gear reduction motor.

[0033] Although the embodiments of the present utility model have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present utility model. The scope of the present utility model is defined by the appended claims and their equivalents.
