Description
Technical Field
The present invention relates to a roller bearing.
Background
The bearing with the seat has the advantages of compact structure, perfect sealing, convenient assembly and disassembly, larger automatic aligning amplitude and the like, so that the frames of a plurality of main machines can adopt the technology of punching or welding formed steel, and the performance of the machine is also improved. It is characterized in that: the outer ring and the bearing seat are matched in a spherical way, so that the bearing seat can automatically center when the bearing seat or the installation reference of the bearing seat deviates from an ideal center, and can be used for a flexible long shaft or a place with a rough installation foundation and bear larger axial load.
The roller bearing based on the ball blocking block consists of an outer cylindrical bearing and a cylindrical bearing seat, the working principle of the roller bearing is basically the same as that of other deep groove ball bearings, but the outer ring of the roller bearing is in spherical contact with the bearing seat to form a free moving state, so that the roller bearing can realize the automatic aligning function.
Disclosure of Invention
The invention provides a roller bearing based on a ball blocking block to solve the technical problems, and solves the problems of difficult assembly and the like.
The invention provides a roller bearing based on a ball blocking block, which comprises an inner ring, an outer ring, a roller, a sealing ring and a connecting seat, wherein the inner ring is provided with a first end and a second end; the outer ring is sleeved on the inner ring, a roller is arranged between the outer ring and the inner ring, and a gap between the outer ring and the inner ring is sealed by the sealing ring. The middle part of one side of the circumference of the inner ring is provided with a groove body, and the position of the inner ring, which is positioned on the groove body, is parallel to the axial direction of the inner ring and is provided with a pin hole; a ball blocking block is arranged in the groove body, a conical hole corresponding to the pin hole of the inner ring is formed in the ball blocking block, and a conical pin is arranged in the pin hole and the conical hole, so that the ball blocking block is locked on the inner ring.
The invention relates to a roller bearing based on a ball blocking block, which is improved in that a raceway is arranged on one side, close to an outer ring, of the ball blocking block; the side of the ball blocking block close to the inner hole is provided with a threaded hole.
Compared with the prior art, the invention has the advantages that the installation of the roller is convenient due to the matching of the inner ring groove body, the pin hole, the ball blocking block and the taper pin, so that the invention has the following advantages: the assembly process is greatly simplified, the working condition is improved, and the service life of the bearing is prolonged.
The roller bearing based on the ball blocking block is composed of an outer cylindrical bearing and a cylindrical bearing seat, the working principle of the roller bearing is basically the same as that of other deep groove ball bearings, but the outer ring of the roller bearing is in spherical contact with the bearing seat, so that a free moving state is formed, and the roller bearing can realize the automatic aligning function.
Drawings
FIG. 1 is a sectional view of a bearing according to the present invention;
fig. 2 is a front view of the bearing of the present invention.
Detailed Description
The invention is shown in fig. 1 and 2, and comprises an inner ring 1, an outer ring 2, a roller 3, a sealing ring 4 and a connecting seat 7. Wherein, the outer ring 2 is sleeved on the inner ring 1, a roller 3 is arranged between the outer ring 2 and the inner ring 1, and a gap between the outer ring 2 and the inner ring 1 is sealed by a sealing ring 4.
In addition, the invention is characterized in that the roller is installed, wherein a groove body for installing the roller is arranged in the middle of one side on the circumference of the inner ring 1, and after the roller is arranged through the groove body, the groove body is blocked by the ball blocking block 6, so that the position of the roller is limited. In order to achieve the blocking locking effect. A pin hole is formed in the inner ring 1 in a position, parallel to the axial direction of the inner ring, of the groove body, and a conical hole corresponding to the pin hole of the inner ring 1 is formed in the ball blocking block 6; a conical pin 5 is arranged in the pin and conical holes, so that the ball block 6 locks onto the inner ring 1 and thus the roller.
In addition, the roller bearing based on the ball blocking block of the invention, as shown in fig. 1, the ball blocking block 6 is provided with a raceway on the side close to the outer ring 2. And a threaded hole is arranged on the side of the ball blocking block 6 close to the inner hole.
One preferred embodiment of the present invention is: taking a roller bearing based on a ball blocking block with a nominal outer diameter of 2978mm as an example: the nominal width of the outer ring is 112mm, and the nominal inner diameter is 2625 mm; the thickness of the ball blocking block is 60mm, the surface roughness is 2.5, the surface roughness of the conical surface is 1.25, and the surface roughness of the raceway surface is 0.65. The rollers are preferably cylindrical rollers, but may also be spherical rollers.
