Description

Technical Field

[0001] The utility model relates to the technical field of bearings, and more specifically, to a high-temperature resistant deep groove ball bearing. Background Art

[0002] Deep groove ball bearings are suitable for high speed or even extremely high speed operation, and are very durable and do not require frequent maintenance. This type of bearing has a small friction coefficient, a high limit speed, and a variety of size ranges and forms. It is used in precision instruments, low-noise motors, automobiles, motorcycles, and general machinery. It is the most widely used type of bearing in the machinery industry. It mainly bears radial loads and can also withstand a certain amount of axial loads. The deep groove ball bearings used in domestic cooling beds have a stamped cage inside the bearing that is generally made of steel plate or brass, but the cages of these two types of bearings are not resistant to high temperatures. For example, a high-temperature resistant deep groove ball bearing described in prior art publication number (CN215171529U) adds a sealing device in the dust cover, while adding liquid lubrication under the effect of graphite solid lubrication. The liquid lubricant is sealed by the sealing ring, and the sealing pad and the sealing ring can enhance the sealing performance. At the same time, the meshing tooth grooves on the dust cover and the fixed block form a dustproof structure to block external dust.

[0003] When the above device is in use, high-temperature resistant graphite material is used as the isolation block, which is highly efficient, does not produce harmful gases at high temperatures, and can prevent the bearing from getting stuck at high temperatures or after rapid cooling. However, its structure is relatively complex, and its internal structure is easily damaged during use. At the same time, the ball is easily shaken inside the graphite isolation block, making its stability worse. Utility Model Content

[0004] In order to overcome the above-mentioned defects of the prior art, the utility model provides a high temperature resistant deep groove ball bearing. The technical problem to be solved by the utility model is: how to increase the stability of the deep groove ball bearing in use.

[0005] To achieve the above object, the utility model provides the following technical solutions: a high temperature resistant deep groove ball bearing, comprising a bearing outer ring, a bearing inner ring is arranged outside the inner end thereof, a first ball groove is opened in the middle of the inner end surface of the bearing outer ring, a second ball groove is opened in the middle of the outer end surface of the bearing inner ring, and balls are arranged inside the first ball groove and the second ball groove;

[0006] A first sealing ring is provided on the outside of the upper end of the ball, and a second sealing ring is provided on the outside of the lower end of the ball. An arc groove is provided on the lower end face of the first sealing ring and the upper end face of the second sealing ring. A sealing gasket is provided on the upper end of the first sealing ring and the lower end of the second sealing ring, and a leak-proof ring is provided on one side of the outer end face of the sealing gasket.

[0007] In a preferred embodiment, a sealing limit groove is provided on one side of the inner end surface of the bearing outer ring and one side of the outer end surface of the bearing inner ring, and an oil filling pipe is provided inside the bearing outer ring;

[0008] The upper end of the bearing outer ring is provided with a limiting groove outside the oil filling pipe, and a sealing member is provided inside the limiting groove. The end faces of the first sealing ring and the second sealing ring are provided with connecting threaded holes on one side close to the arc groove.

[0009] In a preferred embodiment, the sealing limit grooves are provided in two numbers, and are arranged in a mirror image state on both sides of the transverse central axis of the bearing outer ring and the bearing inner ring in the main viewing direction;

[0010] The connection threaded hole is provided with a mounting screw inside, and the connection threaded hole and the mounting screw are both provided in plural numbers and are arranged in a circular array outside the center point of the first sealing ring and the second sealing ring in the top view direction.

[0011] In a preferred embodiment, the inner end surface of the limiting groove is matched with the outer end surface of the sealing member, and the upper end surface and the lower end surface of the bearing outer ring and the bearing inner ring in the main viewing direction are arranged in a coplanar state;

[0012] The first ball groove and the second ball groove have the same curve specifications in the main viewing direction. The number of the balls is multiple and they are arranged in a circular array outside the center point of the outer ring of the bearing in the top viewing direction.

[0013] In a preferred embodiment, the first sealing ring and the second sealing ring are graphite components, the first sealing ring and the second sealing ring have the same specifications, and are arranged in a mirror image state on both sides of the transverse central axis in the main viewing direction;

[0014] There are multiple arc-shaped grooves, which are arranged in a circular array outside the center points of the first sealing ring and the second sealing ring in the top view direction, and the inner end surface of the arc-shaped groove is matched with the outer end surface of the ball.

[0015] In a preferred embodiment, the outer end surface of the sealing gasket is matched with the inner end surface of the sealing limit groove, and there are two leakage-proof rings, and the outer end surfaces of the leakage-proof rings are matched with the inner end surfaces of the bearing outer ring and the bearing inner ring.

[0016] Technical effects and advantages of the utility model:

[0017] When the utility model is actually used, the corresponding settings of the arc groove, the first sealing ring and the second sealing ring can facilitate the separation of the balls. At the same time, when the balls are adapted to the arc groove, the heat generated by the rapid rotation of the balls can be absorbed, so that the heat of the balls can be dissipated to the outside, thereby increasing the heat resistance of the balls. At the same time, when the oil filling pipe, the sealing gasket, the leak-proof ring and the sealing limit groove are correspondingly set, the lubricating oil can be easily introduced into the interior of the second ball groove, and the lubricating oil can be prevented from overflowing, thereby increasing the stability of the deep groove ball bearing when in use.
