Description

Technical Field

[0001] The utility model relates to the technical field of metallurgical equipment, in particular to a lubricating device for a gear box of a straightening machine. Background Art

[0002] A straightening machine is a metallurgical device that straightens a strip by repeatedly bending it using a series of staggered straightening rollers. As the strength and thickness of the strip increase, and as the straightening speed increases, the torque and speed of the gear distribution box in the straightening machine's transmission also increase. To ensure the transmission performance of the gear distribution box and extend the service life of the gearbox bearings and gears, the gear distribution box is typically equipped with a lubrication device.

[0003] Existing lubrication systems for straightening machine gear distribution boxes generally employ two lubrication methods: splash lubrication or point-to-point lubrication. In production practice, when the equipment is not used on a continuous production line, splash lubrication cannot guarantee lubrication of the upper bearings. When the equipment is used on a continuous production line, point-to-point lubrication is employed, requiring lubrication lines to lubricate each bearing. While this configuration ensures lubrication, it complicates the lubrication circuit and increases equipment cost. Therefore, current splash lubrication cannot guarantee lubrication of the upper bearings. Furthermore, point-to-point lubrication requires a more complex lubrication system when the gearbox is complex and a large number of bearings are arranged. Summary of the Invention

[0004] In order to overcome the shortcomings of the existing technology, the purpose of the invention of this utility model is to provide a straightening machine gear box lubrication device, so that the bearings and gears of the straightening machine gear distribution box can be fully lubricated to meet the production needs of the straightening machine.

[0005] In order to achieve the above-mentioned purpose of the invention, the utility model includes a gear box body, a lower lubricating oil tank, an upper lubricating oil tank, an oil return port, a lubricating pump group, a distributor, and a flow regulating valve;

[0006] The lower lubricating oil tank provides lubrication for the lower bearing of the gear box body, and the upper lubricating oil tank provides lubrication for the upper bearing of the gear box body. The lower lubricating oil tank is connected to the lubricating oil inlet port 4, and the upper lubricating oil tank is connected to the lubricating oil inlet port 2; the upper lubricating oil tank is connected to the lower lubricating oil tank via an oil circuit;

[0007] The gear box body is provided with a distribution gear and a reduction gear, the lubrication oil inlet 1 provides lubrication for the distribution gear, and the lubrication oil inlet 3 provides lubrication for the reduction gear;

[0008] An oil return port is provided at the bottom of the gear box body, and the oil return port is connected to the inlet of the lubricating pump group through a lubricating oil pipe, and the outlet of the lubricating pump group is connected to the distributor through a filter and a flow meter, and the distributor is connected to the inlets of lubricating oil inlet 1, lubricating oil inlet 2, lubricating oil inlet 3, and lubricating oil inlet 4 respectively through a flow regulating valve and a flow indicator; the return oil after being connected to the distribution gear, the upper lubricating oil tank, the reduction gear, and the lower lubricating oil tank through the outlets of lubricating oil inlet 1, lubricating oil inlet 2, lubricating oil inlet 3, and lubricating oil inlet 4 is connected to the oil return port.

[0009] Furthermore, the flow regulating valves are provided in four groups, the four groups of flow regulating valves are respectively installed on the distributor, and each group of flow regulating valves is equipped with a group of flow indicators.

[0010] Furthermore, the upper bearing lubricating oil path of the gear box body is connected to the upper lubricating oil tank, and the lower bearing lubricating oil path is connected to the lower lubricating oil tank.

[0011] Furthermore, the bearing holes of the lower bearing and the upper bearing are both provided with oil return holes.

[0012] Compared to existing technologies, the present invention features upper and lower lubricating oil tanks that provide lubrication for the upper and lower bearings of the gearbox, respectively. Lubricating oil inlet ports 1 and 3 provide lubrication for the distribution gear and reduction gear, respectively. Each lubricating oil circuit is equipped with a flow control valve to adjust the oil volume. Oil return holes are located at the bottom of the gearbox, as well as at the bearing holes of the lower and upper bearings, to prevent oil leakage at the shaft diameter. This simple structure, convenient and reliable operation, effectively lubricates the upper and lower bearings and gears, and significantly extends the service life of the gearbox.

DETAILED DESCRIPTION

[0019] like Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 As shown, the utility model mainly includes a gear box body 1, a lower lubricating oil tank 4, an upper lubricating oil tank 5, an oil return port 11, a lubricating pump group 12, a distributor 15, a flow regulating valve 16, and a lubricating oil pipe;

[0020] The bearings in the gear box body 1 are divided into two parts: a lower bearing 2 and an upper bearing 3. The lower lubricating oil tank 4 provides lubrication for the lower bearing 2 of the gear box body 1, and the upper lubricating oil tank 5 provides lubrication for the upper bearing 3 of the gear box body 1. The lower lubricating oil tank 4 is connected to the fourth lubricating oil inlet 18, and the upper lubricating oil tank 5 is connected to the second lubricating oil inlet 9. The fourth lubricating oil inlet 18 and the second lubricating oil inlet 9 are used to replenish oil for the lower lubricating oil tank 4 and the upper lubricating oil tank 5 respectively; the upper lubricating oil tank 5 is connected to the lower lubricating oil tank 4 via an oil circuit;

[0021] The gear box body 1 is provided with a distribution gear 6 and a reduction gear 7. The lubricating oil inlet 1 8 provides lubrication for the distribution gear 6, and the lubricating oil inlet 3 10 provides lubrication for the reduction gear 7.

[0022] An oil return port 11 is provided at the bottom of the gear box body 1. The oil return port 11 is connected to the inlet of the lubricating pump group 12 through a lubricating oil pipe. The outlet of the lubricating pump group 12 is connected to the distributor 15 through a filter 13 and a flow meter 14. The distributor 15 is connected to the inlets of lubricating oil inlet 1 8, lubricating oil inlet 2 9, lubricating oil inlet 3 10 and lubricating oil inlet 4 18 respectively through a flow regulating valve 16 and a flow indicator 17; the return oil after being connected to the distribution gear 6, the upper lubricating oil tank 5, the reduction gear 7 and the lower lubricating oil tank 4 through the outlets of the lubricating oil inlet 1 8, lubricating oil inlet 2 9, lubricating oil inlet 3 10 and lubricating oil inlet 4 18 is connected to the oil return port 11.

[0023] Preferably, the flow regulating valves 16 are provided in four groups, which are respectively mounted on the distributor 15, and each group of flow regulating valves 16 is equipped with a group of flow indicators 17. The four groups of flow regulating valves 16 and flow indicators 17 adjust the oil inlet volume respectively.

[0025] Preferably, the lower bearing 2 and the upper bearing 3 are each provided with an oil return hole at their bearing holes. The oil return hole provided at each bearing position controls the bearing lubricating oil level. The oil return hole should be positioned to ensure that two to three rolling elements within the bearing penetrate the lubricating oil, ensuring that the bearing is fully lubricated. When the lubricating oil reaches the height of the oil return hole, the excess lubricating oil will overflow from the oil return hole and enter the gearbox body 1.

[0026] During use, inject lubricating oil into the gear box body 1. When the gear distribution box of the straightening machine is working, start the lubricating pump group 12 to extract the lubricating oil from the gear box body 1. After filtering the impurities in the lubricating oil through the filter 13, it enters the distributor 15 through the flow meter 14. The distributor 15 distributes the oil circuit, and then the flow regulating valve 16 on the distributor 15 separately adjusts the oil output of the lubricating oil inlet 1 8, the lubricating oil inlet 2 9, the lubricating oil inlet 3 10, and the lubricating oil inlet 4 18. The oil flow of each lubricating oil inlet can be checked through the flow indicator 17. The lubricating oil at the bearing flows back to the gear box body 1 through the return oil port on the gear box body 1.
