[0002] Tapered roller bearing is a common mechanical component, mainly used to bear radial and axial loads. Its basic structure includes bearing inner ring, bearing outer sleeve, roller and cage. The design feature of tapered roller bearing is that its inner ring and outer sleeve have a certain inclination angle, which enables it to bear radial load while also bearing large axial load.

[0003] When assembling or disassembling existing tapered roller bearings, it is generally necessary to clamp or disassemble the inner ring and outer ring of the bearing from the retaining frame and the roller surface by knocking. Knocking can easily cause damage to the bearing components, so improvements are needed. Utility Model Content

[0004] In order to overcome the above defects, the utility model provides a tapered roller bearing that can be quickly disassembled and assembled, which solves the problem that the existing tapered roller bearings are easily damaged when being assembled or disassembled by knocking.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a tapered roller bearing for quick disassembly and assembly, comprising a tapered mounting seat, six groups of limit strips are fixedly installed at equal angles on the inner wall of the tapered mounting seat, six groups of mounting grooves are provided at equal angles on the bottom of the inner wall of the tapered mounting seat, and a slide groove is provided at one end of the mounting groove, a fixed plug rod is slidably installed inside the mounting groove, and both ends of the fixed plug rod pass through the mounting groove, and a limit plate is fixedly installed on the surface of the fixed plug rod on one side of the mounting groove away from the slide groove;

[0006] A fixing spring is provided on the surface of the fixing rod located inside the mounting groove, a rotating plate is provided at the bottom of the conical mounting seat, a retaining frame is provided on the surface of the conical mounting seat, and multiple groups of roller bodies are embedded and rotatably installed on the surface of the retaining frame, bearing rings are provided on the surfaces of the retaining frame and the roller bodies, a fixing tube is provided on the top of the conical mounting seat, and the fixing tube passes through the bearing ring.

[0007] As a further solution of the utility model: six groups of arc grooves are arranged at equal angles on the surface of the rotating plate, and the shifting rod corresponds to the arc grooves, and six groups of clamping grooves are arranged at equal angles on the surface of the rotating plate.

[0008] As a further solution of the utility model: a fixing plate is fixedly installed on the surface of the rotating plate between two adjacent groups of slots, and fixing bolts are provided on the surface of the fixing plate, and the fixing bolts pass through the fixing plate and are connected to the conical mounting seat.

[0009] As a further solution of the utility model: a lever is fixedly installed on one end of the fixed insertion rod located inside the slide slot, and a clamping plate is fixedly installed on one end of the lever rod passing through the slide slot and the arc slot.

[0010] As a further solution of the utility model: six groups of fixed insertion holes are provided at equal angles on the bottom of the surface of the fixed pipe, and the fixed insertion holes correspond to the fixed insertion rods.

[0011] As a further solution of the utility model: a limiting groove is provided on the surface of the fixed pipe between two adjacent groups of fixed insertion holes, and the limiting groove corresponds to the limiting strip.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] 1. The tapered roller bearing for quick disassembly and assembly is provided with a fixed plug rod, a fixed spring, a lever and a rotating plate. The fixing bolts are loosened, and the rotating plate is controlled to rotate at the bottom of the conical mounting seat, so that the lever slides inside the arc groove, driving the fixed socket to retract into the corresponding mounting groove, and the fixed tube is correspondingly inserted into the conical mounting seat so that the fixed socket corresponds to the fixed plug rod. The rotating plate is controlled to reverse, and the fixed plug rod is pushed out of the mounting groove and inserted into the corresponding fixed socket under the rebound action of the fixing spring. The fixing bolts are tightened to fix the rotating plate at the bottom of the conical mounting seat to avoid knocking the bearing for assembly installation or disassembly, which may cause damage to the bearing.

[0014] 2. The tapered roller bearing for quick disassembly and assembly is provided with a tapered mounting seat, a limit strip, a fixing tube and a limit groove. After a retaining frame with multiple groups of roller bodies mounted thereon is sleeved on the surface of the tapered mounting seat, the bearing ring is sleeved on the top of the tapered mounting seat and located on the surface of the retaining frame. The fixing tube is controlled to be inserted into the interior of the tapered mounting seat so that the limit groove is stuck on the surface of the corresponding limit strip. The fixing tube and the tapered mounting seat are connected and fixed, thereby covering both ends of the retaining frame and the roller body inside the bearing ring, reducing dirt from directly falling into the interior of the bearing ring, and ensuring that the tapered mounting seat and the fixing ring do not rotate relative to each other when the bearing rotates.

DETAILED DESCRIPTION

[0020] The technical solution of this patent is further described in detail below in conjunction with specific implementation methods.

[0021] like Figure 1-4 As shown, the utility model provides a technical solution: a tapered roller bearing for quick disassembly and assembly, comprising a tapered mounting seat 1, six groups of limit strips 2 are fixedly installed at equal angles on the inner wall of the tapered mounting seat 1, six groups of mounting grooves 3 are provided at equal angles on the bottom of the inner wall of the tapered mounting seat 1, and a slide groove 4 is provided at one end of the mounting groove 3, a fixed plug rod 5 is slidably installed inside the mounting groove 3, and both ends of the fixed plug rod 5 pass through the mounting groove 3, a lever 8 is fixedly installed on one end of the fixed plug rod 5 located inside the slide groove 4, and a clamping plate 9 is fixedly installed on one end of the lever 8 passing through the slide groove 4 and the arc groove 11. Because the lever 8 and the clamping plate 9 are provided, when the rotating plate 10 is controlled to rotate and the lever 8 slides inside the arc groove 11, it is convenient to control the fixed plug rod 5 to extend or retract into the mounting groove 3, and at the same time, the clamping plate 9 clamps and fixes the rotating plate 10 to ensure that the rotating plate 10 will not separate from the bottom of the tapered mounting seat 1.

[0022] A limiting plate 6 is fixedly installed on the surface of the fixed rod 5 located inside the installation groove 3 and away from the sliding groove 4; a fixing spring 7 is provided on the surface of the fixed rod 5 located inside the installation groove 3. By providing the fixing spring 7, under the rebound action of the fixing spring 7, the limiting plate 6 is pushed toward the side of the installation groove 3 away from the sliding groove 4, thereby driving the fixed rod 5 to move out of the installation groove 3.

[0023] A rotating plate 10 is provided at the bottom of the conical mounting seat 1, and six groups of arc grooves 11 are provided at equal angles on the surface of the rotating plate 10, and the lever 8 corresponds to the arc groove 11, and six groups of clamping grooves 12 are provided at equal angles on the surface of the rotating plate 10. Because the clamping grooves 12 are provided, it is convenient for the processing personnel to detent the clamping grooves 12 to control the rotating plate 10 to rotate at the bottom of the conical mounting seat 1.

[0024] A fixing plate 13 is fixedly installed on the surface of the rotating plate 10 between two adjacent groups of slots 12. A fixing bolt 14 is provided on the surface of the fixing plate 13, and the fixing bolt 14 passes through the fixing plate 13 and is connected to the conical mounting seat 1. By providing the fixing bolt 14, after the fixing tube 18 is clamped and fixed inside the conical mounting seat 1, the fixing bolt 14 is tightened to fix the rotating plate 10 at the bottom of the conical mounting seat 1, ensuring that the rotating plate 10 will not rotate at will at the bottom of the conical mounting seat 1.

[0025] A retainer 15 is provided on the surface of the conical mounting seat 1, and multiple groups of roller bodies 16 are embedded and rotatably installed on the surface of the retainer 15. Bearing rings 17 are provided on the surfaces of the retainer 15 and the roller bodies 16. A fixing tube 18 is provided on the top of the conical mounting seat 1, and the fixing tube 18 passes through the bearing ring 17. Due to the retainer 15, the roller bodies 16 are correspondingly clamped on the surface of the retainer 15 to ensure that the multiple groups of roller bodies 16 do not collide with each other when rotating between the bearing ring 17 and the conical mounting seat 1.

[0026] Six groups of fixing holes 19 are provided at equal angles at the bottom of the surface of the fixing tube 18, and the fixing holes 19 correspond to the fixing rods 5. Because the fixing holes 19 are provided, after the fixing rods 5 are inserted into the corresponding fixing holes 19, the fixing tube 18 is clamped and fixed inside the conical mounting seat 1.

[0027] A limiting groove 20 is provided on the surface of the fixing tube 18 between two adjacent groups of fixing sockets 19, and the limiting groove 20 corresponds to the limiting strip 2. By providing the limiting groove 20, after the fixing tube 18 is inserted into the conical mounting seat 1, the limiting groove 20 is stuck on the corresponding surface of the limiting strip 2, ensuring that the fixing tube 18 and the conical mounting seat 1 can rotate synchronously without relative deflection.

[0028] The working principle of the utility model is:

[0029] Put multiple groups of roller bodies 16 on the surface of the retaining frame 15 accordingly, then put the retaining frame 15 on the surface of the conical mounting seat 1, and put the bearing ring 17 on the surface of the retaining frame 15 at the same time, loosen the fixing bolts 14 to control the rotating plate 10 to rotate at the bottom of the conical mounting seat 1, so that the lever 8 slides inside the arc groove 11, driving the fixed plug rod 5 to retract into the corresponding mounting groove 3, insert the fixed tube 18 into the conical mounting seat 1, so that the limiting groove 20 is stuck on the surface of the corresponding limiting strip 2 until the fixed socket 19 corresponds to the fixed plug rod 5, reverse the rotating plate 10, and under the rebound action of the fixing spring 7, the fixed plug rod 5 is pushed out of the mounting groove 3 and inserted into the corresponding fixed socket 19, the fixing tube 18 is clamped and fixed inside the conical mounting seat 1, and the fixing bolts 14 are tightened to fix the rotating plate 10 at the bottom of the conical mounting seat 1, thereby completing the bearing assembly.
