Description

TECHNICAL FIELD

[0001] The utility model relates to bearing technical field especially relates to a tapered roller bearing. BACKGROUND

[0002] The tapered roller bearing is a common rolling bearing, which uses a tapered roller (also known as a rolling needle) as a rolling element. The inner and outer rings of this bearing are tapered, and the roller and the inner and outer rings have a contact angle. It is usually used to bear large axial and radial loads.

[0003] In the prior art, a tapered roller bearing is disclosed in Chinese Patent Publication No. CN206144995U, which includes an inner ring having a small end face, a large end face, and a tapered outer raceway between the small end face and the large end face. The large end face is axially protruded to form a ring-shaped stopper. The inner ring of the stopper is provided with a first chamfer, which is 40°-50°. By using the above-mentioned scheme, when the tapered roller bearing is installed, the spacer sleeve or shoulder on the large end face of the inner ring will first abut against the ring-shaped stopper formed by the protrusion of the large end face in the axial direction. The inner ring of the stopper is provided with a first chamfer, which can reduce the stress concentration of the stopper. When the bearing is subjected to axial load, the stopper can improve the carrying capacity, thereby improving the service life of the tapered roller bearing.

[0004] Although this kind of bearing has the effect of reducing the stress concentration of the stopper and improving the carrying capacity of the stopper when the bearing is subjected to axial load, thereby improving the service life of the tapered roller bearing, it lacks in filling and lubricating the roller area. Since this kind of bearing does not have a mechanism for supplementing oil to the roller, it will cause the need for workers to disassemble the bearing when supplementing oil, so that the lubricating oil can be evenly applied to the surface of the roller. This kind of oil supplementing method cannot supplement oil to the roller in time when the bearing is rotating. If the bearing lacks lubricating oil during rotation, it will increase the friction between the roller and the inner and outer wall, thereby affecting the rotation of the bearing and also causing great wear to the bearing, affecting its service life.

[0026] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0027] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification. Example

[0028] like Figures 1-6 As shown, this utility model provides a tapered roller bearing, including an outer ring block 1 and an oil replenishing mechanism 6. A load-bearing plate is fixedly installed on the top surface of the outer ring block 1. An inner ring block 3 is inserted inside the outer ring block 1. A roller 4 is arranged in the middle of the inner ring block 3 and the outer ring block 1. A limiting ring 5 is sleeved on the surface of the roller 4. The oil replenishing mechanism 6 includes an oil reservoir 601. An inner column 602 is fixedly installed inside the oil reservoir 601. A spring A603 is arranged inside the inner column 602. Oil drain holes 607 are opened through the surfaces of the oil reservoir 601 and the outer ring block 1. A top block 608 is fixedly installed on the top surface of the limiting ring 5. A protrusion 606 is slidably connected inside the oil drain hole 607. A sealing gasket 605 is fixedly installed on the top surface of the protrusion 606 to seal the oil drain hole 607. A connecting rod 604 is fixedly installed on the top surface of the pad 605. A slide 609 is provided on the inner surface of the outer ring block 1. The roller 4 is conical in shape. The outer surface of the inner ring block 3 and the inner surface of the outer ring block 1 are both in contact with the side of the roller 4. The roller 4 is in rolling connection with the limiting ring 5. The roller 4 is in rolling connection with the inner ring block 3 and the outer ring block 1. One end of the spring A603 is connected to the inner surface of the inner column 602, and the other end is connected to the surface of the connecting rod 604. The connecting rod 604 is in sliding connection with the inner column 602. The sealing pad 605 is made of natural rubber. The top block 608 is in rolling connection with the slide 609. There are two sets of oil storage boxes 601. The two sets of oil storage boxes 601 are symmetrically distributed on both sides of the load-bearing plate.

[0029] In this embodiment: the rotation of the load-bearing plate drives the outer ring block 1 to rotate. When the outer ring block 1 rotates, it drives the roller 4 to roll on the outer surface of the inner ring block 3 and in the limiting ring 5. At this time, the top block 608 on the limiting ring 5 will slide inside the sliding. After the top block 608 moves to the protrusion 606, it will drive the protrusion 606 to move upward. The protrusion 606 will drive the sealing gasket 605 to move upward. After the sealing gasket 605 is raised, the gap between the oil drain hole 607 and the sealing gasket 605 will open. At this time, the lubricating oil in the oil storage box 601 will flow into the slide 609 and the surface of the roller 4 through the oil drain hole 607. Then, the rotation of the roller 4 will make the lubricating oil evenly coated on the inner surface of the outer ring and the outer surface of the inner ring, thereby completing the oil replenishment when the bearing rotates. This avoids the situation where the rotation efficiency is reduced due to lack of lubricating oil when the bearing rotates, and the service life is reduced due to friction damage to the internal components of the bearing. Example

[0030] like Figures 1-6 As shown, a fixing mechanism 7 is provided on the inner surface of the outer ring block 1. The fixing mechanism 7 includes a clamping plate A705 and a clamping plate B707. A limiting groove 701 is opened on the top surface of the outer ring block 1. A limiting rod 702 is fixedly installed inside the limiting groove 701. A spring B 703 is sleeved on the surface of the limiting rod 702. A connecting block 704 is fixedly installed on the bottom surface of the clamping plate A705. A pull handle 706 is fixedly installed on the surface of the clamping plate A705. The clamping plate B707 is fixedly connected to the outer ring block 1. The connecting block 704 is slidably connected to the limiting rod 702. One end of the spring B 703 is connected to the inner surface of the outer ring block 1, and the other end is connected to the surface of the connecting block 704. Rubber pads are fixedly installed on the surfaces of the clamping plates A705 and B707. The clamping plate A705 is slidably connected to the outer ring block 1.

[0031] In this embodiment: by pulling the pull plate, the pull handle 706 will cause the clamping plate A705 to slide on the top surface of the outer ring block 1. After the clamping plate A705 slides away from the side of the oil reservoir 601, the oil reservoir 601 can be pulled out from between the clamping plates A705 and B707. Then, the oil reservoir 601 filled with lubricating oil is placed between the clamping plates A705 and B707. At this time, the pull plate is released, and the connecting block 704 will be subjected to the spring B. The elastic force of 703 causes it to slide on the limit rod 702. When the connecting block 704 moves, it will drive the clamping plate A705 to slide on the top surface of the outer ring block 1 until the oil reservoir 601 is clamped between the clamping plate A705 and the clamping plate B707, thus completing the replacement of the oil reservoir 601. The replaceable design of the oil reservoir 601 changes the oil replenishment method from disassembling and assembling the bearing to disassembling and assembling the oil reservoir 601. This method not only facilitates oil replenishment but also allows the bearing to be replenished with oil without hindering the rotation of the connecting parts.

[0032] The method for using the device and the working principle: when the conical roller bearing needs to be oiled, the load plate is rotated to drive the outer ring block 1 to rotate, and the outer ring block 1 drives the rollers 4 to roll in the outer surface of the inner ring block 3 and the limiting ring 5 when rotating, at this time, the top block 608 on the limiting ring 5 slides in the inner part, after the top block 608 moves to the protruding block 606, the protruding block 606 is driven to move upward, and the sealing gasket 605 is driven to move upward by the protruding block 606, after the sealing gasket 605 is lifted, a gap is formed between the oil discharge hole 607 and the sealing gasket 605, at this time, the lubricating oil in the oil storage box 601 flows into the chute 609 and the surface of the rollers 4 through the oil discharge hole 607, and the lubricating oil is evenly coated on the inner surface of the outer ring and the outer surface of the inner ring by the rotation of the rollers 4, thereby completing the oiling of the bearing during rotation;

[0033] When the top block 608 moves away from the protruding block 606, the connecting rod 604 is driven to slide downward in the inner column 602 by the elastic force of the spring A 603, and the connecting rod 604 drives the sealing gasket 605 to adhere to the top surface of the oil discharge hole 607, so that the oil discharge hole 607 is closed;

[0034] When the oil storage box 601 needs to be replaced, the pull plate is pulled, the pull handle 706 drives the clamping plate A 705 to slide on the top surface of the outer ring block 1, after the clamping plate A 705 slides away from the side surface of the oil storage box 601, the oil storage box 601 is pulled out from the clamping plate A 705 and the clamping plate B 707, and the oil storage box 601 filled with lubricating oil is placed in the middle of the clamping plate A 705 and the clamping plate B 707, at this time, the pull plate is loosened, and the connecting block 704 is driven to slide on the limiting rod 702 by the elastic force of the spring B 703, the connecting block 704 drives the clamping plate A 705 to slide on the top surface of the outer ring block 1 when moving, until the oil storage box 601 is clamped in the middle of the clamping plate A 705 and the clamping plate B 707, thereby completing the replacement of the oil storage box 601.

[0035] The above is only a preferred embodiment of the present application, and is not intended to limit the present application in other forms. Any skilled person in the art can modify or change the above disclosed technical content to equivalent embodiments applied to other fields, but any simple modification, equivalent change and modification made on the basis of the technical essence of the present application to the above embodiments shall fall within the protection scope of the present application.
