DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] See also Figure 1-10 The utility model provides the following technical solutions: a lubrication component of a speed reduction mechanism, including a speed reduction mechanism, the speed reduction mechanism including a housing 1 for loading a worm gear and a worm, the housing 1 being connected with a lubrication component, the lubrication component including an oil filling joint 2, a spring 3, a plunger head 4, an end cover 5, a three-way pipe 6, a first solenoid valve 10, and a second solenoid valve 11, the oil filling joint 2 being connected to the top of the housing 1, an oil filling channel 12 being provided in the oil filling joint 2, a plunger slide groove 13 being adapted to the plunger head 4, the spring 3 and the plunger head 4 being placed in the plunger slide in sequence In the groove 13, the end cover 5 is connected to the end of the oil filling joint 2 away from the shell 1, the three-way pipe 6 includes an oil filling port 7, a first flow channel port 8, and a second flow channel port 9. The oil filling joint 2 is connected to the oil filling port 7 through the end cover 5, and the first solenoid valve 10 and the second solenoid valve 11 are respectively connected to the first flow channel port 8 and the second flow channel port 9. The other ends of the first solenoid valve 10 and the second solenoid valve 11 are used to connect to the oil filling pipeline 19. The bottom of the shell 1 is connected to the third solenoid valve 14, and the other end of the third solenoid valve 14 is used to connect to the waste oil pipeline 20.

[0022] In the above structure, the first solenoid valve 10, the second solenoid valve 11, and the third solenoid valve 14 are all connected to the electrical control device through wires, and the electrical control device is used to control the on and off of each solenoid valve; when the grease in the shell 1 needs to be replaced, the electrical control device controls the passage of each third solenoid valve 14, and the waste grease naturally flows into the waste oil pipeline 20 due to gravity. The oil filling pipeline 19 and the waste oil pipeline 20 can be connected in a curved manner, and a straight pipe is used for illustration in this technical solution.

[0023] The grease in the oil filling pipeline 19 flows from the first solenoid valve 10 to the second solenoid valve 11 as an example:

[0024] When the reduction mechanism reaches the setting for adding grease set by the electrical control device (countdown setting), the first solenoid valve 10 of the electrical controller is opened and the second solenoid valve 11 is disconnected. The grease passes through the oil filling pipeline 19, the three-way pipe 6, the end cover 5 (when passing through the end cover 5, the grease squeezes the plunger head 4, and the spring 3 compresses the grease to flow into the plunger slide groove 13), the oil filling joint 2 and finally flows into the housing 1. The grease falls on the worm gear. After completion, the first solenoid valve 10 of the electrical controller is disconnected and the second solenoid valve 11 is disconnected.

[0025] If multiple groups of reduction mechanisms need to be lubricated, an example is given with three groups of reduction mechanisms (reduction mechanism A, reduction mechanism B, and reduction mechanism C) and the grease in the oil filling pipeline 19 flows from the first solenoid valve 10 to the second solenoid valve 11:

[0026] When the reduction mechanism A needs to be lubricated, the first solenoid valve 10 in the reduction mechanism A is connected and the second solenoid valve 11 is disconnected, and the solenoid valves in the reduction mechanism B and the reduction mechanism C are all disconnected; after the lubrication of the reduction mechanism A is completed, the solenoid valves in the reduction mechanism A are all connected, the solenoid valves in the reduction mechanism C are all disconnected, the first solenoid valve 10 in the reduction mechanism B is connected and the second solenoid valve 1 is disconnected, after the lubrication of the reduction mechanism B is completed, the solenoid valves in the reduction mechanism A and the reduction mechanism B are all connected, the first solenoid valve 10 in the reduction mechanism C is connected and the second solenoid valve 11 is disconnected; after the lubrication of the reduction mechanism C is completed, the solenoid valves in the reduction mechanism A, the reduction mechanism B, and the reduction mechanism C are all disconnected.

[0027] If this housing is not selected, the lubrication assembly can be connected by drilling and tapping holes in the original housing.

[0028] In this embodiment, a retaining ring 15 is provided on the outer wall of the screw of the oil filling joint 2, and a pressure ring 16 is connected to the top of the shell 1. The pressure ring 16 is located above the pressure ring 16, and the pressure ring 16 and the retaining ring 15 are in contact with each other; the thread on the surface of the retaining ring 15 and the thread on the surface of the pressure ring 16 have opposite rotation directions.

[0029] With the above structure, the retaining ring 15 and the pressing ring 16 can effectively prevent the vibration of the internal structure from causing the connection between the oil filling joint 2 and the housing 1 to become loose, thereby ensuring that the connection between the oil filling joint 2 and the housing 1 is tight.

[0030] In this embodiment, a fitting positioning block 17 is disposed at the end of the oil filling port 7 , and a fitting groove 18 matched with the fitting positioning block 17 is formed on the end cover 5 .

[0031] The above structure is adopted to facilitate its installation and improve the assembly speed of the staff, thereby ensuring that the connection relationship between the oil filling port 7 and the end cover 5 is accurate.

[0032] In this embodiment, a tool groove is formed on the upper top surface of the pressure ring 16 .

[0033] In the above structure, the tool groove is hexagonal, and a hollow hexagonal wrench is required to remove the pressure ring 16 to prevent non-maintenance personnel from disassembling it.

[0034] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
