In order to better achieve the power of this type of reducer, lubrication of its internal operating parts is very important.

[0003] At present, most cycloid pinwheel reducers are installed and used horizontally, and the lubricating oil is added and observed through the refueling hole on the side. When the machine is installed and used horizontally, because the refueling hole is perpendicular to the ground and upward, the lubricating oil is easily added and the hidden danger of oil leakage is avoided. The oil level can also ensure that the internal parts are immersed, and there is no problem with the lubrication effect.

[0004] However, when the existing cycloid pinwheel reducer is installed and used vertically, due to the special working conditions and the oil filling hole being set in the middle of the side of the machine, the following problems arise during the lubrication and maintenance of the machine:

[0005] 1. The lubricating oil cannot reach the appropriate oil level during oil change and refilling;

[0006] 2. Refueling is difficult and the proper oil level cannot be ensured due to side leakage.

For ordinary technicians in this field, the specific meanings of the above terms in the embodiments of the present invention can be understood according to specific circumstances.

[0050] The embodiments of the present utility model are described in detail below with reference to the accompanying drawings. Example

[0051] See also Figure 1 to Figure 3 This embodiment provides a reduction motor, including a reduction motor 1, a vertical reduction motor 2 and a lubricating oil replenishing mechanism 3.

[0052] The vertical reducer 2 is installed and used vertically; the input end of the vertical reducer 2 is transmission-connected with the output end of the reducer motor 1 .

[0053] In this embodiment, preferably, the vertical reducer 2 is a vertical cycloid pinwheel reducer.

[0054] The lubricating oil replenishing mechanism 3 includes a first oil delivery pipe 31 , a second oil delivery pipe 32 and an oil sight tube 33 .

[0055] The first oil delivery pipe 31 has a first end and a second end; the second end 311 of the first oil delivery pipe is connected to the top or upper side of the vertical reducer 2 and is connected to the inner cavity of the vertical reducer 2; the second end 312 of the first oil delivery pipe extends vertically upward as a refueling port, or extends obliquely upward.

[0056] In this embodiment, preferably, the second end 311 of the first oil delivery pipe is connected to the top of the vertical reducer 2, and the second end 312 of the first oil delivery pipe extends vertically upward.

[0057] The second oil delivery pipe 32 has a first end and a second end. The second end 321 of the second oil delivery pipe is connected to the lower side of the vertical reducer 2 and communicates with the inner cavity of the vertical reducer 2 .

[0058] In a specific implementation scenario, the first oil pipeline 31 and / or the second oil pipeline 32 are metal pipes.

[0059] The oil sight tube 33 is made of a transparent material; the oil sight tube 33 is located between the first oil pipeline 31 and the second oil pipeline 32 , and both ends of the oil sight tube 33 are connected to the first oil pipeline 31 and the second oil pipeline 32 , respectively.

[0060] In this embodiment, preferably, the oil sight tube 33 is vertically arranged; in other embodiments, the oil sight tube 33 may also be inclined.

[0061] The second end 312 of the first oil delivery pipe extends vertically upward as a refueling port, or extends obliquely upward, so that it is convenient to add lubricating oil to the inner cavity of the vertical reducer 2 through the refueling port, and the added lubricating oil is not easy to leak. After the first oil delivery pipe 31, the second oil delivery pipe 32 and the oil sight tube 33 are connected, a pipeline structure is formed that can observe the oil level in the inner cavity of the vertical reducer 2 through the oil sight tube 33, so that it is convenient to add lubricating oil to a suitable oil level. Example

[0062] This embodiment is a further improvement made on the basis of Embodiment 1.

[0063] See also Figure 1 to Figure 3 In this embodiment, the second end 312 of the first oil delivery pipe is detachably connected to a vent cap 34 to discharge the high-temperature positive-pressure oil and gas generated by the rising oil temperature inside the vertical reducer 2, so as to prevent the high-temperature positive-pressure oil and gas from entering the reducer motor 1 (the input end of the vertical reducer 2 is transmission-connected with the output end of the reducer motor 1, and there is a possibility that the high-temperature positive-pressure oil and gas enter the reducer motor 1) and cause motor failure.

[0064] It should be noted that the above-mentioned vent cap 34 is a prior art, belonging to a type of oil-gas separation device, which plays a role in separating oil and gas. This embodiment does not improve the structure of the vent cap 34 itself. Example

[0065] See also Figure 1 to Figure 3 This embodiment further improves the lubricating oil replenishing mechanism 3 provided in Embodiment 1, so that the lubricating oil replenishing mechanism 3 has the function of automatically replenishing lubricating oil.

[0066] In this embodiment, the lubricating oil replenishing mechanism 3 further includes a first liquid level sensor 35, a second liquid level sensor 36, an automatic control valve 37, a controller (not shown in the figure) and an oil replenishing pump (not shown in the figure).

[0067] The first liquid level sensor 35 is installed on the oil sight tube 33 .

[0068] The second liquid level sensor 36 is installed on the oil sight tube 33 and is located below the first liquid level sensor 35 .

[0069] The automatic control valve 37 is connected to the second end 322 of the second oil pipeline; the automatic control valve 37 has a valve oil inlet 371 and a valve oil outlet 372 which can be opened and closed respectively.

[0070] The controller is electrically connected to the automatic control valve 37 .

[0071] The oil charge pump is connected to the valve oil inlet 371 .

[0072] The automatic control valve 37 has a valve oil inlet 371 and a valve oil outlet 372 which can be opened and closed respectively. The functions are:

[0073] On the one hand, the first liquid level sensor 35 and the second liquid level sensor 36 are located at two detection positions on the oil sight tube 33, and the two detection positions represent the preset upper limit and lower limit of the oil level respectively. When the oil level in the oil sight tube 33 reaches the detection position of the second liquid level sensor 36, the second liquid level sensor 36 transmits a signal to the corresponding controller, and the controller opens the valve oil inlet 371 (before, the valve oil inlet 371 and the valve oil outlet 372 are both in a closed state), and starts the oil replenishment pump, so as to replenish the lubricating oil into the inner cavity of the vertical reducer 2; when the oil level in the oil sight tube 33 reaches the detection position of the first liquid level sensor 35, the controller closes the valve oil inlet 371.

[0074] On the other hand, when the lubricating oil in the inner cavity of the vertical reducer 2 needs to be replaced, the valve oil outlet 372 can be opened to drain the lubricating oil, and then the vent cap 34 can be removed to manually add the lubricating oil from the second end 312 of the first oil pipe to complete the replacement of the lubricating oil.

[0075] Finally, it should be noted that the above are only preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention may be subject to various modifications and variations. In the absence of conflicts, the embodiments of the present application and the features in the embodiments may be combined with each other at will. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
