DETAILED DESCRIPTION

[0029] 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.

[0030] See also Figure 1-5 The utility model provides a technical solution: a gear reduction box with self-lubricating function, including a lower gear box 1, an upper gear box 2, a mounting mechanism 3, a mounting block 4, a mounting plate 5, a mounting rod 6, an auxiliary plate 7, a fixing sleeve 8, an input transmission shaft 9, an output transmission shaft 10, a reduction gear set 11, a lubricating oil tank 12, an eccentric wheel 13, a movable rod 14, a sealing plug 15, a movable column 16, a spring 17 and a lubrication channel 18.

[0031] When using the gear reducer with self-lubricating function, when disassembling and assembling the gear reducer, if Figure 1 , Figure 2 and Figure 3 As shown, the upper gear box 2 is engaged with the upper end of the lower gear box 1. Combined with the setting of the mounting mechanism 3, the mounting mechanism 3 is symmetrically arranged at the left and right ends of the lower gear box 1, and the mounting mechanism 3 includes a mounting block 4 in a "T"-shaped structure, a mounting plate 5 for connection, a mounting rod 6 fixedly connected to the side of the mounting plate 5, an auxiliary plate 7 fitted on the outer sides of the lower gear box 1 and the upper gear box 2, and a fixing sleeve 8 for locking. First, the mounting plate 5 is sleeved on the outer side of the mounting block 4, and then the mounting plate 5 is respectively fitted between the lower gear box 1 and the upper gear box 2, and then the mounting mechanism 3 is pulled outward to The mounting plate 5 is mounted so that the mounting plate 5 and the mounting block 4 are engaged with each other, and then the auxiliary plate 7 is sleeved on the outer side of the mounting rod 6 so that the auxiliary plate 7 is fitted on the outer side of the lower gear box 1 and the upper gear box 2. Then, the fixing sleeve 8 threadedly connected to the outer surface of the mounting rod 6 is rotated so that the fixing sleeve 8 is fitted on the outer side of the auxiliary plate 7, thereby facilitating the position limiting between the mounting plate 5 and the mounting block 4. Through the above operation, it is convenient to limit the position between the lower gear box 1 and the upper gear box 2, and complete the disassembly and assembly of the gear box, thereby facilitating the maintenance and repair of the parts inside the gear box;

[0032] like Figure 4 and Figure 5As shown, when the external driving device drives the input transmission shaft 9 to rotate, the input transmission shaft 9 is connected to the output transmission shaft 10 through the reduction gear set 11, so as to achieve the effect of deceleration. At the same time, during the rotation of the output transmission shaft 10, the front end of the output transmission shaft 10 is fixedly connected with the eccentric wheel 13, and the output transmission shaft 10 drives the eccentric wheel 13 to rotate. The upper end of the eccentric wheel 13 is fitted with the movable rod 14. When the convex edge of the eccentric wheel 13 rotates to an upward direction, it drives the movable rod 14 to slide with the lubricating oil tank 12. At this time, the movable rod 14 drives the sealing plug 15 to move upward, and the sealing plug 15 drives the movable rod 14 to slide. The column 16 slides in the lubricating oil tank 12, and the sealing plug 15 squeezes the spring 17, causing the spring 17 to undergo elastic deformation. At this time, the sealing plug 15 releases the blockage of the front end opening of the lubricating oil tank 12. At this time, the lubricating oil inside the lubricating oil tank 12 flows through the opening and the lubricating channel 18 to the connection position between the transmission shaft and the bearing, thereby achieving a good self-lubricating effect without the need to manually add lubricating oil. In addition, the diameter size of the movable rod 14 is equal to the size of the slot at the lower end of the lubricating oil tank 12. When the movable rod 14 slides with the lubricating oil tank 12, the outflow of lubricating oil from the slot at the connection between the movable rod 14 and the lubricating oil tank 12 can be ignored.

[0033] When the convex edge of the eccentric wheel 13 rotates to the downward direction, the spring 17 restores its elastic deformation, driving the movable column 16 and the sealing plug 15 to move downward. The sealing plug 15 blocks the opening on the front side of the lubricating oil tank 12, and drives the eccentric wheel 13 to rotate through the output transmission shaft 10, thereby achieving cyclic and continuous lubrication of the connection between the transmission shaft and the bearing, which is very convenient to use.

[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.
