Description

Technical Field

[0001] This utility model belongs to the field of speed reducer technology, specifically relating to a speed reducer for conveyors. Background Technology

[0002] When a conveyor is in operation, a reducer is needed to drive the conveyor rollers so that the conveyor can work properly. A reducer is a mechanical device designed to reduce the speed of the input shaft and increase the torque of the output shaft, while maintaining a relatively stable speed and torque of the output shaft. However, existing reducers have certain drawbacks. For example, Chinese patent CN 221274266U discloses a speed reduction transmission device for a chain conveyor, which includes a variable frequency motor, a planetary reducer, and a torque support device. The output end of the variable frequency motor is connected to the input end of the planetary reducer. The torque support device includes a torque plate. The rear housing of the planetary reducer is tightly fixed to the torque plate in the axial direction. Although this device can drive the conveyor, lubricating oil is added inside the device to reduce wear on the gears during operation. However, as the usage time increases, wear between the gears will gradually produce metal shavings. Furthermore, since the lubricating oil has a limited lifespan, it needs to be replaced. However, this device requires complete disassembly to replace the lubricating oil, which is difficult and inefficient. Utility Model Content

[0028] 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.

[0029] Please see Figures 1-10 As shown, this utility model provides the following technical solution:

[0030] A conveyor reducer includes a transmission component 1 for driving the conveyor. The transmission component 1 includes a housing part and a transmission part. The housing part has an internal space for accommodating lubricating oil and the transmission part. A conveying component 2 is installed on the housing part. The conveying component 2 has a conveying channel for conveying lubricating oil along a preset path. The inlet and outlet ends of the conveying channel are connected to the accommodating space. A filter shell 26 is installed between the inlet and outlet ends. A detachable bottom cover 25 is screwed onto one end of the filter shell 26. A filter cover 210 is fixedly connected to the side of the bottom cover 25 facing the filter shell 26. The filter cover 210 is located inside the filter shell 26.

[0031] With the above technical solution, when personnel need to install the device, the transmission component 1 is installed on one side of the conveyor, and the transmission part is connected to the conveyor and the drive motor. The drive motor drives the transmission part inside the housing to rotate, and the transmission part drives the conveyor to work, thereby transporting items. When the transmission part is working, the conveyor component 2 delivers lubricating oil, which circulates inside the transmission part to lubricate it. As the lubricating oil flows, it flows to the inside of the filter housing 26, where it is filtered by the filter cover 210 inside the filter housing 26. The lubricating oil is filtered to remove metal shavings and other impurities, which are then trapped inside the filter housing 26. The filtered lubricating oil is then transported back to the receiving space through the conveying channel, thus continuously lubricating the transmission parts. When the lubricating oil needs to be changed, the bottom cover 25 is rotated to separate it from the filter housing 26, allowing the lubricating oil to drain through the filter housing 26. New lubricating oil is then added to the filter housing 26. After adding the lubricating oil, the bottom cover 25 is screwed back onto the filter housing 26, thus completing the lubricating oil change without the need for complete disassembly of the device.

[0032] When the device is in use, in order to continuously filter metal debris from inside the housing and ensure that the lubricating oil continuously lubricates the transmission parts, such as... Figure 7 As shown, a rotating shaft 28 is rotatably connected to the side of the bottom cover 25 facing the filter housing 26, and a scraper 29 for scraping the filter cover 210 is fixedly connected to the circumference of the rotating shaft 28.

[0033] In this embodiment, when the device filters lubricating oil through the filter cover 210, the rotating shaft 28 rotates relative to the bottom cover 25, thereby driving the scraper 29 to rotate. The scraper 29 scrapes the liquid inlet side of the filter cover 210, thereby cleaning the impurities on the filter cover 210 and preventing metal debris and other impurities from clogging the filter cover 210, so that the filter cover 210 can continuously filter lubricating oil.

[0034] Furthermore, regarding how the rotating shaft 28 rotates in this utility model, as follows: Figure 5-Figure 7 As shown, a motor 211 is fixedly connected to the side of the bottom cover 25 away from the rotating shaft 28. The output end of the motor 211 is connected to the rotating shaft 28. A handle 27 is fixedly connected to the side of the bottom cover 25 away from the rotating shaft 28. The handle 27 is located on the side of the motor 211.

[0035] In this embodiment, when it is necessary to drive the rotating shaft 28 to rotate, the motor 211 works to drive the rotating shaft 28 to rotate, and the rotating shaft 28 drives the scraper 29 to rotate, thereby allowing the scraper 29 to scrape the filter cover 210. When it is necessary to remove the bottom cover 25, the bottom cover 25 can be separated from the filter shell 26 by rotating the handle 27, making it convenient for personnel to change the lubricating oil or clean the inside of the filter shell 26.

[0036] Specifically, in one embodiment, regarding the aforementioned conveyor 2:

[0037] like Figure 2 , Figures 4-7 As shown, the conveying component 2 includes a pump body 22. The pump body 22 has a first oil inlet pipe 23 and an oil outlet pipe 21 connected to its inlet and outlet ends, respectively. The inlet end of the first oil inlet pipe 23 is fixedly connected to the filter housing 26. The side of the filter housing 26 away from the first oil inlet pipe 23 is fixedly connected to the bottom of the housing portion, and the outlet end of the oil outlet pipe 21 is fixedly connected to the top of the housing portion.

[0038] In this embodiment, when it is necessary to deliver lubricating oil, the pump body 22 operates, thereby generating suction in the first oil inlet pipe 23 and the second oil inlet pipe 24, thereby drawing the lubricating oil inside the housing and delivering the lubricating oil to the inside of the filter housing 26, where it can be filtered through the filter cover 210.

[0039] Furthermore, in this utility model, regarding the aforementioned shell portion, as follows: Figures 1-5 As shown, the housing part includes an outer shell 11, and the transmission part is installed inside the outer shell 11.

[0040] Specifically, in one embodiment, regarding the aforementioned transmission part, such as Figure 8As shown, the transmission part includes a first connecting shaft 12, a second connecting shaft 14 and a third connecting shaft 17. A first pinion 13, a second pinion 16 and a second large gear 18 are respectively sleeved on the first connecting shaft 12, the second connecting shaft 14 and the third connecting shaft 17. A first large gear 15 is also sleeved on the second connecting shaft 14. The first large gear 15 is located on one side of the second pinion 16. The first pinion 13 meshes with the first large gear 15, and the second pinion 16 meshes with the second large gear 18.

[0041] In this embodiment, a drive motor and a conveyor are connected via a first connecting shaft 12 and a third connecting shaft 17, respectively. When the drive motor operates, it drives the first connecting shaft 12 to rotate, which in turn drives the first pinion 13 to rotate. The first pinion 13 then drives the first large gear 15 to rotate, which in turn drives the second connecting shaft 14 to rotate the second pinion 16. The second pinion 16 then drives the second large gear 18 to rotate, which in turn drives the third connecting shaft 17 to rotate. The third connecting shaft 17 then drives the conveyor to operate, thereby moving the items.

[0042] Furthermore, when personnel need to connect the conveyor and drive motor, in order to facilitate the connection of the device, such as... Figures 1-2 As shown, the first connecting shaft 12 and the third connecting shaft 17 are both equipped with a connecting member 3 at one end extending outside the housing 11. The end of the connecting member 3 away from the housing 11 forms a connecting cavity for the insertion of the drive shaft.

[0043] In this embodiment, the first connecting shaft 12 is connected to the drive motor via the coupling 3, and the third connecting shaft 17 is connected to the conveyor via the coupling 3, thereby driving the conveyor to work.

[0044] Furthermore, in this utility model, regarding the aforementioned coupling 3, as follows: Figures 1-2 , Figures 9-10 As shown, the following implementation method is provided:

[0045] Implementation Method 1

[0046] The coupling 3 includes two connecting covers 31, which are fixedly connected to the ends of the first connecting shaft 12 and the third connecting shaft 17 away from the outer casing 11, respectively, and the connecting cavity is formed inside the connecting cover 31.

[0047] In this embodiment, when it is necessary to connect a drive motor, the first connecting shaft 12 is connected to the drive motor through the connecting cavity on the connecting cover 31, and the third connecting shaft 17 is connected to the conveyor through the connecting cavity on the connecting cover 31, so that the conveyor can be driven to work.

[0048] Implementation Method 2

[0049] The coupling 3 includes two connecting covers 31, which are fixedly connected to the ends of the first connecting shaft 12 and the third connecting shaft 17 away from the outer casing 11, respectively. The connecting cavity is formed inside the connecting cover 31, and two side grooves 32 are formed on the circumferential surface of the connecting cover 31. Side plates 33 are fixedly connected to both sides of the connecting cover 31 near the two side grooves 32, and a screw 34 is screwed between the two side plates 33.

[0050] In this embodiment, when it is necessary to connect the drive motor, the first connecting shaft 12 is connected to the drive motor through the connecting cavity on the connecting cover 31, and the third connecting shaft 17 is connected to the conveyor through the connecting cavity on the connecting cover 31, so that the conveyor can be driven to work. Then, the screw 34 is screwed to the side plate 33 to complete the connection with the drive motor and the conveyor.

[0051] To facilitate connection of the connecting cavity with shaft-type parts, the diameter of the connecting cavity gradually increases from one end near the outer casing 11 to the other end.

[0052] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art 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 appended claims and their equivalents.
