Description

Technical Field

[0001] The utility model belongs to the technical field of tapered roller bearings, in particular to a lubrication and filling component of a tapered roller bearing. Background Art

[0002] Bearings are an important component in modern mechanical equipment. Common bearings are generally tapered roller bearings. During the processing of bearings, it is generally necessary to use a lubrication filling assembly to add lubricating oil to its rolling elements, which can reduce friction and wear, extend fatigue life, and discharge friction heat and cooling.

[0003] Existing lubrication filling assemblies generally achieve full lubrication of the bearing by rotating the oil filling device around the center of the bearing driven by a motor. However, the existing oil filling device is generally fixedly connected to the motor, and it is difficult to adjust the distance between the oil filling device and the center of the motor. As a result, the existing lubrication filling assemblies can generally only be used to fill oil to bearings of a single diameter, reducing applicability. Utility Model Content

[0004] In order to overcome the above-mentioned defects, the utility model provides a lubrication and filling assembly for a tapered roller bearing, which solves the problem that the existing oil filling device is generally fixedly connected to the motor, and it is difficult to adjust the distance between the oil filling device and the center of the motor, resulting in the existing lubrication and filling assembly generally being able to only fill oil for bearings of a single diameter, reducing the applicability.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a lubrication and filling assembly for a tapered roller bearing, comprising a workbench, two electric push rods are fixedly connected to the top of the workbench, one end of the two electric push rods is fixedly connected to a moving plate, the bottom of the moving plate is fixedly connected to a motor, the output end of the motor is fixedly connected to a rotating rod, a plurality of limiting holes are provided on the rotating rod, a moving frame is slidably connected to the rotating rod, a limiting rod is slidably connected to the moving frame, a tension spring is sleeved on the limiting rod, and an oil filling device is provided at the bottom of the moving frame.

[0006] As a further solution of the utility model: four columns are fixedly connected to the bottom of the workbench, and two fixing plates are fixedly connected to the top of the workbench.

[0007] As a further solution of the utility model: a bearing body is arranged on the top of the workbench, and two clamping plates are slidably connected to the top of the workbench.

[0008] As a further solution of the utility model: a feed port is provided on the oil injection device, and a pull column is fixedly connected to one end of the limit rod.

[0009] As a further solution of the utility model: a plastic pad is fixedly connected to the clamping plate, and two movable rods are fixedly connected to one side of the clamping plate.

[0010] As a further solution of the utility model: a spring is sleeved on the movable rod, and a round cap is fixedly connected to one end of the movable rod away from the clamping plate.

[0011] Compared with the prior art, the beneficial effects of the utility model are:

[0012] 1. The lubrication filling component of the tapered roller bearing is provided with a limit hole, a tension spring, a limit rod, a pull column and a moving frame. When it is necessary to fill oil to the bearing bodies of different diameters, the pull column is pulled to drive the limit rod to move upward, so that the limit rod is disengaged from the limit hole. At this time, the limit hole does not limit the limit rod, and the moving frame is pushed to drive the oil filling device to move on the rotating rod. When the oil filling device moves to a suitable position, the pull column is released, the tension spring is reset and the pull column and the limit rod are pulled downward, so that the limit rod is inserted into the limit hole, and the oil filling device can be fixed. The filling component can quickly adjust the distance between the oil filling device and the motor, so that the bearing bodies of different diameters can be fully filled with lubricating oil, thereby improving applicability.

[0013] 2. The lubrication and filling assembly of the tapered roller bearing is provided with a clamping plate, a spring, a movable rod and a bearing body. When in use, one of the clamping plates is first pulled to increase the distance between the two clamping plates, and the bearing body is placed between the two clamping plates. When the clamping plates are released, the spring resets and pushes the movable rod and the clamping plate to clamp and position the bearing body, so that the center of the bearing body can be aligned with the motor, avoiding deviation of the position of the bearing body during oil filling and improving the oil filling quality.

DETAILED DESCRIPTION

[0019] The technical solution of this patent is further described in detail below in conjunction with specific implementation methods.

[0020] like Figure 1-4 As shown, the utility model provides a technical solution: a lubrication and filling assembly for a tapered roller bearing, comprising a workbench 1, with two electric push rods 7 fixedly connected to the top of the workbench 1. Because the electric push rods 7 are provided, when a person puts a bearing body 5 between two clamping plates 4, the electric push rods 7 are started to lift a movable plate 6 to prevent the movable plate 6 from obstructing the work of the person. One end of the two electric push rods 7 is fixedly connected to the movable plate 6, four columns 2 are fixedly connected to the bottom of the workbench 1, and two fixed plates 3 are fixedly connected to the top of the workbench 1.

[0021] A motor 8 is fixedly connected to the bottom of the movable plate 6, and a rotating rod 9 is fixedly connected to the output end of the motor 8. A plurality of limit holes 10 are provided on the rotating rod 9. A bearing body 5 is provided on the top of the workbench 1. Two clamping plates 4 are slidably connected to the top of the workbench 1. Because the clamping plates 4 are designed with an arc surface, they can fit with the bearing body 5, thereby improving the clamping stability.

[0022] A moving frame 11 is slidably connected to the rotating rod 9, and a limiting rod 20 is slidably connected to the moving frame 11. A plastic pad 16 is fixedly connected to the clamp plate 4. Because the plastic pad 16 is provided, the plastic pad 16 is soft in texture. When the plastic pad 16 contacts the bearing body 5, the wear of the bearing body 5 caused by the clamp plate 4 can be reduced, thereby protecting the bearing body 5. Two movable rods 18 are fixedly connected to one side of the clamp plate 4, and a spring 17 is sleeved on the movable rod 18. A round cap 19 is fixedly connected to the end of the movable rod 18 away from the clamp plate 4.

[0023] A tension spring 13 is sleeved on the limit rod 20, and an oil injection device 15 is arranged at the bottom of the movable frame 11. A feed port 14 is arranged on the oil injection device 15. Since the feed port 14 is funnel-shaped with a large opening, it is convenient for personnel to add lubricating oil to the inside of the oil injection device 15, thereby improving work efficiency. A pull column 12 is fixedly connected to one end of the limit rod 20.

[0024] The working principle of the utility model is:

[0025] When in use, first pull one of the clamping plates 4 to increase the distance between the two clamping plates 4, and place the bearing body 5 between the two clamping plates 4. When the clamping plates 4 are released, the spring 17 is reset to push the clamping plates 4 to clamp and position the bearing body 5. At this time, the motor 8 and the oil injection device 15 are started, and the motor 8 drives the rotating rod 9, the moving frame 11 and the oil injection device 15 to rotate, and the oil injection device 15 fully injects oil into the rolling elements of the bearing body 5.

[0026] When it is necessary to inject oil into the bearing bodies 5 of different diameters, the pull column 12 is pulled to drive the limit rod 20 to move upward, so that the limit rod 20 is disengaged from the limit hole 10. At this time, the limit hole 10 does not limit the limit rod 20. The movable frame 11 is pushed to drive the oil injection device 15 to move on the rotating rod 9. When the oil injection device 15 moves to the appropriate position, the pull column 12 is released, the tension spring 13 is reset and pulls the pull column 12 and the limit rod 20 downward, so that the limit rod 20 is inserted into the limit hole 10. The oil injection device 15 can be fixed, thereby adjusting the position of the oil injection device 15, and then oil can be injected into the bearing bodies 5 of different diameters.

[0027] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood by specific circumstances.

[0028] The above describes in detail the preferred implementation of this patent, but this patent is not limited to the above implementation. Various changes can be made within the knowledge scope of ordinary technicians in this field without departing from the purpose of this patent.
