Referring to fig. 1 to 3, fig. 1 is a front view of the present invention, fig. 2 is a sectional view of fig. 1 in a direction A-A, and fig. 3 is a schematic view of the bearing inner race according to the present invention.
The utility model provides an adjustable permanent magnet damping slide bearing who presets damping moment of torsion, includes the bearing inner race 10 and the bearing outer lane 7 of cooperation suit, and the contact surface of bearing inner race 10 and bearing outer lane 7 includes one section conical surface, and bearing inner bore 3 has been seted up to the center department of bearing inner race 10. The axial length of the bearing outer ring 7 is greater than that of the bearing inner ring 10, the part, close to the small end of the conical surface, of the inner wall of the bearing outer ring 7 is in threaded connection with an end cover 2, the end cover 2 is fixedly connected with a permanent magnet 5 facing the bearing inner ring 10, and a magnetic force adjusting gap 6 is reserved between the permanent magnet 5 and the bearing inner ring 10.
During installation, the bearing outer ring 7 is installed in the bearing seat hole, and the bearing inner ring 10 is installed on the rotary shaft 4 in an interference fit mode. And then the end cover 2 is rotated, and because the end cover 2 is in threaded connection with the bearing outer ring 7, the end cover 2 can move along the axial direction when the end cover 2 is rotated, and then the permanent magnets 5 are driven to move, so that the permanent magnets 5 are close to or far from the bearing inner ring 10. When the permanent magnet 5 approaches the bearing inner ring 10, the magnetic force adjusting gap 6 is reduced, the suction force of the permanent magnet 5 to the bearing inner ring 10 is enhanced, the pressure of the bearing inner ring 10 to the bearing outer ring 7 is increased on the conical surface part of the contact surface, and further the friction resistance of the bearing inner ring 10 during rotation is increased, so that the purpose of increasing the preset damping torque is realized. On the contrary, the end cover 2 is rotated to enable the permanent magnet 5 to be far away from the bearing inner ring 10, the magnetic force adjusting gap 6 is increased, and the purpose of reducing the preset damping torque can be achieved. Therefore, the invention can adjust the preset damping torque, thereby expanding the application range of the same bearing.
When the damping bearing is used, the bearing inner ring 10 and the bearing outer ring 7 can generate abrasion on the contact surface along with the increase of the service time, so that the size between the bearing inner ring 10 and the bearing outer ring 7 on the contact surface is changed, the friction resistance is reduced, and at the moment, under the action of the magnetic force of the permanent magnet 5, the bearing inner ring 10 moves towards the permanent magnet 5, so that the friction resistance between the bearing inner ring 10 and the bearing outer ring 7 is increased, the purposes of stabilizing damping torque and automatically compensating abrasion in the rotation process of the damping bearing are realized, and the service life of the bearing is prolonged.
The end cover 2 is annular, and the inner diameter of the end cover 2 is larger than the aperture of the bearing inner hole 3, so that a gap is formed between the end cover 2 and the rotary shaft 4, the rotary shaft 4 is prevented from being influenced by the end cover 2 in the rotation process, the running stability of the rotary shaft 4 can be ensured, and the abrasion of the rotary shaft 4 to the end cover 2 can be avoided. In other embodiments of the invention, the end cap 2 may have other shapes, as long as it is ensured that the outer wall thereof is threadably connected to the bearing outer race 7 and that the inner wall is not in contact with the rotary shaft 4.
The end cover 2 is also provided with an adjusting indication mark 12, and the adjusting indication mark 12 can prompt when the end cover 2 is rotated, so that the influence of the error of a user on the bearing performance caused by the opposite rotation direction of the end cover 2 to the required direction is avoided.
In order to make the rotation of the end cover 2 more convenient, the end cover 2 is also provided with a plurality of damping torque adjusting holes 1, a tool can be used for being inserted into the damping torque adjusting holes 1, and then the end cover 2 is driven to rotate through the rotating tool, so that the time and the labor are saved. Specifically, the number of the damping torque adjusting holes 1 is two, and the connecting line of the centers of the two damping torque adjusting holes 1 is collinear with one diameter of the bearing inner hole 3. Correspondingly, the embodiment provides a special tool, which consists of a horizontal rod and two vertical rods, wherein the two vertical rods are respectively fixedly arranged at two ends of the horizontal rod, when in use, the two vertical rods are respectively inserted into the two damping torque adjusting holes 1, and then the end cover 2 can be driven to rotate by rotating the horizontal rod.
The permanent magnet 5 is cylindrical, the magnetizing direction of the permanent magnet 5 is axial magnetizing, namely, the direction of magnetic force lines is the axial direction of the permanent magnet 5, the inner diameter of the permanent magnet 5 is larger than the aperture of the bearing inner hole 3, and the outer diameter of the permanent magnet 5 is smaller than the inner diameter of the bearing outer ring 7. The gap is generated between the permanent magnet 5 and the rotating shaft 4, so that the rotating shaft 4 is prevented from being influenced by the permanent magnet 5 in the rotating process, the running stability of the rotating shaft 4 can be ensured, and the abrasion of the rotating shaft 4 to the permanent magnet 5 can be avoided. Meanwhile, a gap is reserved between the permanent magnet 5 and the bearing outer ring 7. In other embodiments of the invention, the permanent magnet 5 may be of other shapes as long as it is ensured that its outer wall is not in contact with the bearing outer ring 7 and that the interior is not in contact with the rotation shaft 4.
The outer wall of the bearing inner ring 10 is also provided with a lubricating medium groove 11, and when the bearing is assembled, a proper amount of lubricating grease is coated in the lubricating medium groove 11, the lubricating grease plays a role in lubricating a contact surface, so that the consistency of friction force on the contact surface of the bearing in use is ensured, and corrosion or adhesion is prevented. Further, on the development surface of the outer wall of the bearing inner ring 10, the center line of the lubricating medium groove 11 is a function curve, so that the lubricating grease can be uniformly distributed on the contact surface. Since the rotational speed of the damping bearing is extremely low during operation, and generally, the number of rotations per rotation is not more than one, the lubrication groove 11 is used only for storing the grease, and the grease does not flow in the lubrication groove 11, so that the lubrication groove 11 may be provided in any shape as long as the grease can be uniformly distributed.
