As shown in fig. 1, the oil discharge device for the thin oil lubrication bearing box comprises a sleeve 1, a valve 2 and a plug 3, wherein one end of the sleeve 1 is sleeved in one end of the valve 2, and the other end of the sleeve 1 is matched with an oil discharge hole 7; the end cap 3 is arranged at one end, far away from the sleeve 1, of the valve 2, and the end cap 3 is used for plugging the valve 2. The utility model discloses can effectively solve the problem of thin oil lubrication bearing box waste oil recovery difficulty, can avoid the unable whole recovery of waste oil and avoid the pollution that waste oil caused the environment effectively.

The oil discharge hole 7 arranged on the general bearing box is rarely used basically, and only needs to be plugged simply by a plug, so that oil leakage is avoided, and oil can be discharged when necessary. However, for the thin oil lubricated bearing box, the lubricating oil in the bearing box must be replaced regularly, so that the oil drain hole 7 is frequently used, a small amount of waste oil is easily leaked out in the process of removing the plug 3 and connecting the pipeline of the waste oil collecting device, and the waste oil is frequently used and accumulated more, so that the waste oil is not easy to clean, and the waste oil flows out along the wall of the bearing box to pollute the environment. Therefore, the valve 2 is additionally arranged at the joint of the oil discharge hole 7, the plug 3 can be conveniently replaced by a pipeline connected with a waste oil collecting device by closing the valve 2, and then the valve 2 is opened to collect waste oil; and because the valve 2 increases the extension length of the oil discharge hole 7, even if a little waste oil remains at one end of the valve 2 close to the plug 3, the cleaning is also convenient, and the valve is not limited to a step that the plane of the oil discharge hole 7 of the bearing box is 2-3mm higher than the plane of the box wall. The valve 2 can not be directly connected to the oil discharge hole 7, and a sleeve 1 is sleeved on the valve 2 to enable the oil discharge hole 7 and the valve 2 to be communicated in a sealing mode.

In this embodiment, the sleeve 1 is a galvanized steel pipe, the sleeve 1 is provided with an external thread, and the sleeve 1 is in threaded connection with the oil drain hole 7. The sleeve 1 is a hard pipe, the whole device can be effectively fixed on an oil discharge hole 7 of the bearing box through threaded connection, and the relative hose is not easy to damage. The length of the sleeve 1 protruding out of the valve 2 is consistent with the depth of the sleeve 1 inserted into the oil drain hole 7, and a first sealing ring 4 is further arranged between the valve 2 and the oil drain hole 7. After the sleeve 1 is inserted into the oil discharge hole 7, the sleeve is further sealed by the first seal ring 4, so that waste oil is prevented from overflowing from a gap between the sleeve 1 and the oil discharge hole 7. Meanwhile, the first sealing ring 4 is equivalently clamped between the edge of the valve 2 and the opening of the oil discharge hole 7 and is used for increasing friction force and preventing the sleeve 1 from being screwed out along the thread as the valve 2 rotates randomly to drive the sleeve 1 to rotate; the first sealing ring 4 also provides a force for the valve 2 to move outwards away from the oil drain hole 7, so that the threads of the sleeve 1 and the oil drain hole 7 are tightened to increase friction force, and the possibility that the sleeve 1 and the oil drain hole 7 are separated from each other is avoided.

In this embodiment, an annular protrusion 11 is disposed at one end of the sleeve 1 connected to the valve 2, and a groove 21 adapted to the protrusion 11 is disposed inside the valve 2. The recess 21 looks adaptation that sleeve pipe 1 passes through bellying 11 and valve 2 to make sleeve pipe 1 rotate relative to valve 2, but can not axial displacement in order to prevent to break away from each other, the setting can make things convenient for sleeve pipe 1's fixed like this, because after the installation, the position of valve 2 is the protrusion setting on oil drain hole 7, touch valve 2 and rotate by on-the-spot foreign object easily, consequently, the cooperation of this bellying 11 and recess 21 further avoids valve 2 to be collided by the foreign object and drives sleeve pipe 1 and rotate, thereby avoid sleeve pipe 1 to receive the revolving force and make its screw thread break away from with oil drain hole 7. Moreover, the filling of the first sealing ring 4 can also play a sufficient sealing role.

In this embodiment, the plug 3 comprises a screw 31 and a nut 32 connected together, the screw 31 is in threaded connection with the valve 2, and the diameter of the nut 32 is larger than the diameter of the opening at the end of the valve 2. The threaded connection of the screw 31 and the valve 2 is better secured and sealed, and the nut 32 is wrapped outside the opening at the end of the valve 2 to form a further sealing effect. The valve 2 is a stainless steel ball valve, and the plug 3 is made of stainless steel material. The valve 2 and the plug 3 as well as the threaded connection between the valve 2 and the sleeve 1 are easy to bear force, and the connection is more stable. In addition, the plug 3 can also be set to be in the shape of a soft rubber plug, but needs to be made of corrosion-resistant materials to avoid corrosion of waste oil to the plug.

In this embodiment, a second sealing ring 5 is provided between the nut 32 and the valve 2. Also fix and seal between end cap 3 and the valve 2 through threaded connection cooperation second sealing washer 5, second sealing washer 5 fills up the clearance between the corresponding opening edge of nut 32 edge and valve 2 to form chucking and sealing action, the principle is the same with the connected mode of above-mentioned valve 2 and oil drain hole 7 cooperation first sealing washer 4. And a third sealing ring 6 is fixedly arranged at the tail end of the screw rod 31 in the valve 2, and the third sealing ring 6 is matched with a pipeline for leading out waste oil. Meanwhile, a third sealing ring 6 is arranged in the valve 2 for further sealing, so that oil leakage accidents are not easy to happen. And the third sealing ring 6 can also be used as a sealing connecting piece to be fixedly connected with a rubber tube of a waste oil collecting device, so that the oil leakage phenomenon is not easy to occur from a valve during oil drainage.

As shown in figure 2, this device is installed on oil drain hole 7, when bearing box need change lubricating oil, pull down end cap 3 of 2 free ends of valve, connect a PVC flexible glue pipe, the flexible glue pipe disect insertion waste oil collection device in, open valve 2 and box top oil filler point, waste oil passes through valve 2 and the automatic waste oil collection device that goes into of rubber tube, thereby avoided waste oil to flow along the bearing box wall, can avoid the unable whole pollution that retrieves and avoid waste oil to the environment to cause effectively.

It is above only the utility model discloses a preferred embodiment, the utility model discloses a scope of protection does not only confine above-mentioned embodiment, the all belongs to the utility model discloses a technical scheme under the thinking all belongs to the utility model discloses a scope of protection. It should be noted that, for those skilled in the art, various modifications and decorations can be made without departing from the principle of the present invention, and these modifications and decorations should also be regarded as the protection scope of the present invention.
