Description
Technical Field
The invention relates to a cylindrical roller bearing with a seat, and belongs to the technical field of roller bearings with seats.
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 cylindrical roller bearing with seat consists of two parts, including outer cylindrical bearing and cylindrical bearing seat, and has basically the same working principle as other deep groove ball bearings, but the outer ring of the bearing is in spherical contact with the bearing seat to form free moving state and the bearing has automatic aligning function.
Disclosure of Invention
The invention provides a cylindrical roller bearing with a seat for solving the technical problems, and solves the problems of difficult assembly and the like.
The invention provides a cylindrical roller bearing with a seat, which comprises an inner ring, an outer ring, a roller and a sealing ring, wherein the inner ring is provided with a bearing seat; 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. Wherein, the middle part of the outer ring is provided with a threaded hole along the radial direction, and a connecting seat is fixed through the threaded hole; the connecting seat comprises a threaded column with one end provided with threads and a spherical rotary structure with the other end being big in head and small in neck.
Four threaded holes are uniformly distributed on the outer ring of the bearing along the circumferential direction at intervals of 90 degrees of rotation angle, and therefore four connecting seats are fixed.
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, the lubricating quality is improved, the friction heating and the energy consumption loss are reduced, and the service life of the bearing is greatly prolonged.

fig. 2 is a front view of the bearing of the present invention.
Detailed Description
As shown in fig. 1 and 2, the invention comprises an inner ring 1, an outer ring 2, a roller 3 and a sealing ring 4; 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.
Wherein, the middle part of the outer ring 2 is provided with a threaded hole along the radial direction, and a connecting seat 7 is fixed through the threaded hole; the connecting base 7 comprises a threaded column with one end provided with threads and a spherical rotary structure with the other end being big in head and small in neck. Under preferred mode, four screw holes are evenly distributed on the outer ring 2 along the circumferential direction at intervals of 90 degrees of rotation angle, and therefore four connecting seats 7 are fixed.
In addition, the improvement of the invention also lies in the installation mode of the roller, wherein, one side on the circumference of the inner ring 1 is provided with a groove body used for installing the roller in the middle part, and after the roller is arranged through the groove body, the groove body is blocked by a ball blocking block 6, thereby limiting the position of the roller. 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 bore, whereby the ball blocking piece 6 locks onto the inner ring 1 and thus the roller.
In addition, as shown in fig. 1, the ball blocking block 6 of the cylindrical roller bearing with the seat is provided with a raceway on one 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: take a cylindrical roller bearing with a seat 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.
Claims (2)
