Abstract
Description
Technical Field
[0001] The utility model relates to a seat bearing, in particular to a novel high-temperature resistant seat bearing. Background Art
[0002] Pillow block bearings are one of the core components in mechanical transmission systems. They play a role in supporting and reducing friction in various mechanical equipment. They can ensure smooth relative movement between mechanical parts, reduce energy loss, and improve the accuracy and reliability of mechanical transmission.
[0003] The bearing seat is composed of a mounting seat, an outer ring, an inner ring and balls. The rotating shaft is installed in the inner ring. When the rotating shaft rotates, the inner ring will also rotate. When the bearing seat is running at high speed, there will be high-speed friction between the outer ring, inner ring and balls. The friction will generate a lot of heat, causing the temperature of the bearing seat to rise rapidly. The interior of the bearing seat is relatively closed, making it difficult for heat to dissipate, resulting in heat accumulation inside the bearing seat. High temperature will cause the material properties of the bearing seat to change, such as reduced hardness, deformation, etc., and in severe cases, it may even cause damage to the bearing seat. Utility Model Content
[0004] In order to overcome the disadvantages that the interior of the bearing is relatively closed, which makes it difficult for heat to dissipate, thereby causing heat to accumulate inside the bearing, and high temperature will cause changes in the material properties of the bearing, such as reduced hardness and deformation, and in severe cases even damage to the bearing, the utility model provides a new type of high-temperature resistant bearing.
[0005] The technical solution is: a new type of high-temperature resistant seated bearing, including a support seat, an outer ring, an inner ring, balls, graphite blocks and a fixed cover. The outer ring is connected to the support seat, and balls and graphite blocks are evenly spaced between the inside of the outer ring and the outside of the inner ring. A fixed cover for protecting the outer ring and inner ring is connected to the top of the support seat by screws, and both the outer ring and the inner ring are located inside the fixed cover.
[0006] As an improvement to the above solution, a first heat dissipation hole is provided on the support base, and a second heat dissipation hole is provided on the fixed cover, and the heat on the outer ring is dissipated through the first heat dissipation hole and the second heat dissipation hole.
[0007] As an improvement to the above solution, a sealing ring is further included. The front and rear sides of the support seat are both connected with sealing rings, and the sealing ring is in contact with the inner wall of the fixed cover.
[0008] As an improvement to the above solution, a rubber pad is further included, and the bottom of the support seat is connected to the rubber pad.
[0009] As an improvement to the above solution, a mounting hole is provided on the support seat.
[0010] The beneficial effects are: the utility model can support the rotating shaft through the outer ring, the inner ring and the ball, ensuring the stability of the rotating shaft, the graphite block can still maintain a stable structure in a high temperature environment, and the graphite block can quickly conduct the heat inside the support seat and the fixed cover to avoid heat accumulation inside the support seat and the fixed cover, thereby preventing the outer ring, the inner ring and the ball from being damaged due to excessive temperature.

[0016] The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.
[0017] like Figure 1-Figure 4 As shown, a new type of high-temperature resistant seated bearing includes a support seat 1, an outer ring 2, an inner ring 3, balls 4, graphite blocks 5 and a fixed cover 6. The outer ring 2 is connected to the support seat 1, and balls 4 and graphite blocks 5 are evenly spaced between the inside of the outer ring 2 and the outside of the inner ring 3. The number of balls 4 and graphite blocks 5 is the same, and the balls 4 and graphite blocks 5 are staggered. A fixed cover 6 for protecting the outer ring 2 and the inner ring 3 is connected to the top of the support seat 1 by screws. The outer ring 2 and the inner ring 3 are both located in the fixed cover 6. First heat dissipation holes 7 are evenly spaced on the front and back sides of the support seat 1, and second heat dissipation holes 8 are evenly spaced on the front and back sides of the fixed cover 6. Mounting holes 11 are provided on the left and right sides of the bottom of the support seat 1.
[0018] like Figure 1 and Figure 2 As shown, a sealing ring 9 is also included. The front and rear sides of the support base 1 are connected with sealing rings 9, and the sealing ring 9 is in contact with the inner wall of the fixed cover 6.
[0019] like Figure 1 As shown, a rubber pad 10 is also included, and the bottom of the support seat 1 is connected to the rubber pad 10.
[0020] The staff puts the bolts into the mounting holes 11, installs the support seat 1 in the use position with the bolts, and then installs the shaft in the inner ring 3. The shaft contacts the inner wall of the sealing ring 9. The sealing ring 9 can seal the gap between the outer ring 2 and the inner ring 3 and the shaft to prevent dust from entering between the inside of the outer ring 2 and the outside of the inner ring 3. The rubber pad 10 has good elasticity and vibration absorption performance, which can effectively absorb and disperse the vibration generated when the machine is running, reducing the impact of vibration on the support seat 1. When the shaft rotates, the outer ring 2, inner ring 3 and ball 4 support the shaft to ensure the stability of the shaft. At the same time, the inner ring 3 and ball 4 The balls 4 and the graphite blocks 5 will also rotate. The graphite blocks 5 have extremely high high temperature resistance, so that the graphite blocks 5 can still maintain a stable structure in a high temperature environment. The graphite blocks 5 have good thermal conductivity and can quickly conduct the heat inside the support base 1 and the fixed cover 6 to avoid heat accumulation inside the support base 1 and the fixed cover 6, thereby preventing the outer ring 2, the inner ring 3 and the balls 4 from being damaged due to excessive temperature. The heat on the outer ring 2 is dissipated through the first heat dissipation holes 7 and the second heat dissipation holes 8, thereby further reducing the temperature of the outer ring 2 and preventing the outer ring 2 from being damaged due to excessive temperature.
[0021] The above description is merely an example of the implementation of the present invention and is not intended to limit the present invention. Any equivalent substitutions made within the principles of the present invention shall be included within the scope of protection of the present invention. Any matters not fully described in the present invention are prior art known to those skilled in the art.
