Description

Technical Field

[0001] The utility model relates to the technical field of bearing seats, in particular to a bearing seat which is convenient for oil injection. Background Art

[0002] Where there is a bearing, there must be a support point. The inner support point of the bearing is the shaft, and the outer support is what is commonly known as the bearing seat. After the bearing seat has been used for a long time, it needs to be oiled and maintained so that it can maintain normal operation.

[0022] 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.

[0023] See also Figure 1-3A bearing seat that is convenient for oil injection includes a lower shell seat 1 and an upper shell seat 2. A bolt 3 is threadedly connected between the lower shell seat 1 and the upper shell seat 2. The bottom of the bolt 3 extends downward into the interior of the lower shell seat 1. The inner walls of the lower shell seat 1 and the upper shell seat 2 are provided with a bearing groove 4, and the bearing can be installed in the bearing groove 4.

[0024] See also Figure 2-3 A cavity 5 is provided inside the upper shell seat 2, and a spring 6 is arranged inside the cavity 5. A square plate 7 is clamped on the top of the spring 6. The cross-sections of the cavity 5 and the square plate 7 are rectangular. A clamping groove corresponding to the spring 6 is provided at the bottom of the square plate 7. Four oil holes 8 are provided on the surface of the square plate 7. The four oil holes 8 are evenly distributed. A plug body 9 is fixedly installed on the inner top wall of the cavity 5. The plug body 9 corresponds to the oil hole 8, and the plug body 9 is inserted into the inside of the oil hole 8. When the spring 6 pushes the square plate 7 upward, the plug body 9 will be inserted into the oil hole 8 to prevent leakage of the lubricating oil.

[0025] See also Figure 2-3 A blocking bead 10 is arranged on the top of the square plate 7, and a groove corresponding to the blocking bead 10 is provided on the top of the square plate 7. Bead holes 11 are provided at both ends of the cavity 5, the diameter of the spring 6 is larger than the diameter of the bead hole 11, the bead hole 11 is tangent to the inner wall of the blocking bead 10, and the bead hole 11 is in a trumpet shape, with a small diameter at one end and a large diameter at the other end. The spring 6 pushes the blocking bead 10 to embed into the bead hole 11, which can block the bead hole 11 to prevent the leakage of lubricating oil.

[0026] Working principle: When in use, use the needle tube to suck up the lubricating oil in advance, and the head of the needle tube will squeeze the blocking bead 10 hard. The blocking bead 10 and the square plate 7 will move downward, and the oil hole 8 on the square plate 7 will separate from the plug body 9. The spring 6 is passively compressed and finally squeezes the needle tube. The lubricating oil enters the oil hole 8 from the bead hole 11, then enters the cavity 5, and finally enters the bearing groove 4, so as to lubricate and replenish the bearing and also achieve the purpose of oiling the bearing seat.

[0027] On the contrary, the spring 6 can push the square plate 7 upward, and the oil hole 8 and the plug body 9 match each other to prevent the injected lubricating oil from leaking back. At the same time, the plugging bead 10 will also be embedded in the bead hole 11 to prevent the lubricating oil from leaking again.

[0028] 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.
