Description

Technical Field

[0001] The present application relates to the technical field of bearings, and in particular to a high-strength outer spherical bearing and a method for using the same. Background Art

[0002] The outer spherical bearing is a special rolling bearing with a spherical rolling surface. It is usually composed of an inner ring, an outer ring, rolling elements and a cage. The outer spherical bearing has a large angular displacement capability and free rolling capability, and can withstand large radial and axial loads. The bearing seat is the supporting structure for the installation of the outer spherical bearing, usually made of metal or alloy materials, and has internal grooves and mounting holes that match the outer spherical bearing.

[0003] In the prior art, the related technology of the outer spherical bearing can refer to the Chinese patent with the announcement number CN203023280U, which discloses an outer spherical bearing, which includes an outer ring with a spherical outer surface, an inner ring, a plurality of rolling elements arranged between the outer ring and the inner ring, and a cage for supporting the plurality of rolling elements, the cage is made of glass fiber reinforced polyamide 66 material, and the outer ring and the inner ring are plated with an anti-corrosion layer on the surface. In this application, the outer ring and the inner ring are made of ordinary bearing steel, and the surface is plated with an anti-corrosion layer, which improves the corrosion resistance of the bearing. The hard chrome layer is used to enhance the wear resistance of the surface and improve the service life of the bearing; In terms of the sealing performance of existing outer spherical bearings, the internal sealing is often achieved only by sealing rings. After the sealing rings fall off, the balls are often exposed to the outside, and they often do not have the function of double sealing. At the same time, at this stage, bearings mainly achieve pressure resistance through balls. The balls of existing outer spherical bearings are widely spaced and the number is limited. Adding rolling elements will permanently increase friction. However, if the outer spherical bearings are not increased, once the load suddenly increases, the rolling elements may be damaged due to insufficient strength. Summary of the invention

[0004] The purpose of the present application is to provide a high-strength outer spherical bearing and a method of using the same.

[0005] In the first aspect, the present application provides a high-strength outer spherical bearing adopts the following technical solution: A high-strength outer spherical bearing comprises an outer ring, an inner ring is arranged at the inner center of the outer ring, a first groove is arranged on the outer wall of the inner ring and the middle part of the inner wall of the outer ring, balls are arranged between the outer ring and the inner ring, the balls are embedded in the first groove, second grooves are arranged on both sides of the first groove, a retaining mechanism is arranged on the outer walls of multiple groups of the balls, the retaining mechanism comprises a No. 1 and a half cage, a No. 2 and a half cage, a support ring, a ball groove, a rivet and a lubricating oil chamber, a No. 2 and a half cage is arranged on one side of the No. 1 and a half cage, the No. 1 and a half cage matches the No. 2 and a half cage, support rings are arranged at the edges of the No. 1 and a half cage and the No. 2 and a half cage, and the support ring matches the second groove.

[0006] By adopting the above technical solution, the outer ring and the inner ring are allowed to rotate through the balls, thereby realizing the basic rotation function of the bearing. The balls are limited by arranging them in the first groove, so that they can only rotate between the outer ring and the inner ring. The holding mechanism can hold multiple groups of balls in position to prevent them from moving at will, and separate the balls to prevent them from colliding with each other, thereby reducing wear. During installation, the No. 1.5 cage and the No. 2.5 cage are relatively arranged and installed, and it is ensured that the ball grooves can cover the balls in sequence during installation. The outer wall width of the support ring is close to the distance between the outer ring and the inner ring, thereby playing a certain dust-proof role without the need for a dust-proof component and improving the support of the bearing.

[0007] A ball groove is arranged in the middle of the No. 1 and a half cage and the No. 2 and a half cage, the inner wall of the ball groove matches the outer wall of the ball, the ball is embedded in the ball groove, the No. 1 and a half cage and the No. 2 and a half cage are connected by rivets, and lubricating oil chambers are arranged on the surfaces of the No. 1 and a half cage and the No. 2 and a half cage.

[0008] By adopting the above technical solution, the ball groove plays the role of limiting the ball, ensuring that the ball is evenly distributed, so that the load is evenly distributed on the entire bearing to avoid local overload. The No. 1 and a half cages and the No. 2 and a half cages are spliced ​​so that the two sets of ball grooves form a closed annular shape. The lubricating oil chamber is an oil storage tank reserved in the middle of the retaining mechanism, which can store excess lubricating oil, thereby achieving fixed-point lubrication. It ensures that the lubricating oil directly acts on the contact point between the ball and the inner and outer rings, which is the part of the bearing that needs lubrication most, thereby improving the service life of the bearing.

[0009] The inner wall and outer wall surfaces of the support ring are arranged with limiting grooves, a movable block is embedded in the middle of the limiting groove, the end of the movable block is rotatably connected to an auxiliary roller through a movable shaft, one end of the auxiliary roller extends to the outside of the movable block, and a spring is connected to the middle inner wall of the limiting groove, and the end of the spring away from the inner wall of the limiting groove is connected to the movable block.

[0010] By adopting the above technical solution, the limit groove plays a limiting role, the movable block can perform telescopic movement in the limit groove, and the auxiliary roller can rotate on the top of the movable block through the movable shaft, so as to provide a certain degree of support when the bearing rotates under high load, reduce the load force of the ball, and increase the service life of the bearing. Through the connection of the spring, the movable block can be kept in the embedded limit groove when the bearing is at a low temperature.

[0011] A lifting mechanism is provided on both sides of the spring, and the lifting mechanism includes a fixed cylinder, a telescopic top block and a disguised telescopic block. The fixed cylinder is connected to the inner wall of the limiting groove, and a telescopic top block is embedded in the middle inner wall of the fixed cylinder. The end of the telescopic top block away from the fixed cylinder is connected to the movable block, and a disguised telescopic block is provided between the fixed cylinder and the movable block. The material of the disguised telescopic block is modified thermoplastic plastic.

[0012] By adopting the above technical solution, the lifting mechanism can push the movable block to lift up when the ball rotates under high heat and high load, and then the auxiliary roller abuts against the second groove to assist in supporting the rotation. When the bearing rotates under high load, the ball will generate a large amount of heat due to the increase in load and high-speed rotation. The heat is transferred to the inside of the support ring through the ball, and then transmitted to the disguised telescopic block. The material of the disguised telescopic block is modified thermoplastic plastic. When heated, the thermoplastic plastic usually expands due to the intensified movement of molecular chain segments, and shrinks due to the rearrangement of molecular chains after cooling. Therefore, when the temperature rises, the volume of the disguised telescopic block will expand rapidly, thereby pushing the telescopic top block to move outward, thereby driving the movable block to move to the outside of the limit groove, so that the auxiliary roller abuts against the second groove to assist in supporting the rotation, sharing part of the load of the ball and improving the service life of the bearing.

[0013] The inner wall of the fixed cylinder is provided with a heat conducting sheet, the support ring is made of beryllium copper alloy, and sealing rings are provided on both sides of the holding mechanism, and the sealing rings are arranged in the middle of the outer ring and the inner ring.

[0014] By adopting the above technical solution, the heat conductive sheet can accelerate the heat conduction effect of the support ring on the disguised telescopic block. The support ring is a beryllium copper alloy. While the support ring seals the ball to a certain extent, the beryllium copper alloy material itself combines the excellent thermal conductivity of copper and the high strength of beryllium, and has an excellent heat dissipation effect. The sealing ring further improves the sealing of the bearing to prevent external dust from entering the bearing.

[0015] The outer wall of the outer ring is spherical, and a bearing seat is sleeved on the outside of the outer ring. The inner wall of the bearing seat is arc-shaped, and the inner wall of the bearing seat matches the outer wall of the outer ring. An oil filling groove is provided on one side of the top of the bearing seat, and the end of the oil filling groove is connected to the inner wall of the bearing seat. A sealing cover is provided on the top of the oil filling groove.

[0016] By adopting the above technical solution, the bearing seat plays the role of connecting, fixing and supporting the outer ring, ensuring that it maintains the correct position during operation, and providing self-aligning space. Since the outer wall of the outer ring and the inner wall of the bearing seat are both arc-shaped, the outer ring can be offset and aligned inside the bearing seat, thereby allowing the bearing to make slight angular adjustments to adapt to the deflection or bending of the shaft. Lubricating oil can be added through the oil filling groove to reduce the friction between the outer ring and the bearing seat, and the sealing cover plays a sealing role.

[0017] The outer wall of the bearing seat is connected with a heat sink, a cooling ventilation pipe is arranged on one side of the bottom of the bearing seat, and mounting holes are arranged on the edge of the bearing seat.

[0018] By adopting the above technical solution, the heat sink improves the heat dissipation capacity of the bearing seat, allowing it to cool quickly. The cooling ventilation duct can accelerate the cooling effect through natural wind. The bearing seat can be installed in a fixed position through the mounting holes and bolts.

[0019] A fixing pin is arranged on an inner wall of one side of the inner ring, and outer walls of the outer ring and the inner ring are both covered with a wear-resistant layer, and the material of the wear-resistant layer is a chrome-plated coating.

[0020] By adopting the above technical solution, the fixing pin is used to connect the shaft body that needs to be rotated, thereby realizing rotation, and the wear-resistant layer improves the overall wear resistance of the bearing.

[0021] A method for using a high-strength outer spherical bearing comprises the following steps: Step 1: embed the inner ring inside the outer ring, add a predetermined number of balls to the gap between the outer ring and the inner ring, then set the inner ring at the center of the outer ring so that it is in a coaxial position, and evenly set the balls in the first groove, and then apply a certain amount of lubricating oil to the ball position; Step 2: When installing, install the No. 1 and a half cage and the No. 2 and a half cage opposite to each other, and ensure that the ball grooves can cover the outer wall of the ball in sequence, and the No. 1 and a half cage and the No. 2 and a half cage are fixedly connected by rivets; Step 3: Sleeve the bearing seat on the outer wall of the outer ring. The four ends of the bearing seat are fixedly connected to the mounting holes through bolts, allowing the bearing to be slightly adjusted in angle to adapt to the deflection or bending of the shaft, and a certain amount of lubricating oil is added through the oil filling groove; Step 4: When the bearing rotates under high load, the ball will generate a lot of heat due to the increase in load and high-speed rotation. The heat is transferred to the inside of the support ring through the ball, and then transmitted to the disguised telescopic block. The volume of the disguised telescopic block will expand rapidly when the temperature rises, thereby pushing the telescopic top block to move outward, thereby driving the movable block to move to the outside of the limit groove, so that it can then abut against the second groove through the auxiliary roller to assist in supporting the rotation.

[0022] In summary, the present application includes at least one of the following beneficial technical effects: 1. The holding mechanism can hold multiple groups of balls in position to prevent them from moving at will, and separate the balls to prevent them from colliding with each other, thereby reducing wear. During installation, the No. 1.5 cage and the No. 2.5 cage are installed opposite to each other. During installation, ensure that the ball grooves can cover the balls in sequence. The outer wall width of the support ring is close to the distance between the outer ring and the inner ring, thereby playing a certain dust-proof role without the need for dust-proof components and improving the support of the bearing; 2. When the bearing rotates under high load, the ball will generate a lot of heat due to the increase in load and high-speed rotation. The heat is transferred to the inside of the support ring through the ball, and then transmitted to the disguised telescopic block. When the temperature rises, the volume of the disguised telescopic block will expand rapidly, thereby pushing the telescopic top block to move outward, thereby driving the movable block to move to the outside of the limit groove, so that it can then abut against the second groove through the auxiliary roller to assist in supporting the rotation, share part of the load of the ball, and increase the service life of the bearing.

The two grooves 5 match each other, and the balls 4 are arranged between the outer ring 1 and the inner ring 2 so that they can rotate, realizing the basic rotation function of the bearing. The balls 4 are limited by arranging them in the first groove 3, so that they can only rotate between the outer ring 1 and the inner ring 2. The retaining mechanism 6 can hold multiple groups of balls 4 in position to prevent them from moving at will, and separate the balls 4 to prevent them from colliding with each other, thereby reducing wear. During installation, the first and a half retaining frames 601 and the second and a half retaining frames 602 are relatively arranged and installed. During installation, ensure that the ball grooves 604 can cover the balls 4 in sequence. The outer wall width of the support ring 603 is close to the distance between the outer ring 1 and the inner ring 2, thereby playing a certain dust-proof role without the need for a dust-proof component and improving the support of the bearing.

[0027] A ball groove 604 is arranged in the middle of the first and second half cages 601 and 602. The inner wall of the ball groove 604 matches the outer wall of the ball 4. The ball 4 is embedded in the ball groove 604. The first and second half cages 601 and 602 are connected by rivets 605. Lubricating oil chambers 606 are arranged on the surfaces of the first and second half cages 601 and 602. The ball groove 604 plays the role of limiting the ball 4, ensuring that the ball 4 is evenly distributed. The load is evenly distributed on the entire bearing to avoid local overload. The No. 1 and a half cage 601 and the No. 2 and a half cage 602 are spliced ​​so that the two sets of ball grooves 604 form a closed annular shape. The lubricating oil chamber 606 is an oil storage tank reserved in the middle of the retaining mechanism 6, which can store excess lubricating oil to achieve fixed-point lubrication. It ensures that the lubricating oil directly acts on the contact point between the ball 4 and the inner and outer rings 1, which is the part of the bearing that needs lubrication most, thereby improving the service life of the bearing.

[0028] The inner wall and outer wall surfaces of the support ring 603 are arranged with limiting grooves 7, and a movable block 8 is embedded in the middle of the limiting groove 7. The end of the movable block 8 is rotatably connected to an auxiliary roller 9 through a movable shaft, and one end of the auxiliary roller 9 extends to the outside of the movable block 8. A spring 10 is connected to the middle inner wall of the limiting groove 7, and the end of the spring 10 away from the inner wall of the limiting groove 7 is connected to the movable block 8. The limiting groove 7 plays a limiting role, and the movable block 8 can perform telescopic movement in the limiting groove 7. The auxiliary roller 9 can rotate on the top of the movable block 8 through the movable shaft, so as to provide a certain degree of support when the bearing rotates under high load, reduce the load force of the ball 4, and improve the service life of the bearing. Through the connection of the spring 10, the movable block 8 can be kept in the embedded limiting groove 7 when the bearing is at a low temperature.

[0029] Lifting mechanisms 11 are provided on both sides of the spring 10. The lifting mechanisms 11 include a fixed cylinder 12, a telescopic top block 13 and a disguised telescopic block 14. The fixed cylinder 12 is connected to the inner wall of the limiting groove 7. The middle inner wall of the fixed cylinder 12 is embedded with a telescopic top block 13. The end of the telescopic top block 13 away from the fixed cylinder 12 is connected to the movable block 8. A disguised telescopic block 14 is provided between the fixed cylinder 12 and the movable block 8. The material of the disguised telescopic block 14 is modified thermoplastic plastic. The lifting mechanism 11 can push the movable block 8 to lift up when the ball 4 rotates under high heat and high load, and then the auxiliary roller 9 abuts against the second groove 5 to assist in supporting the rotation. When the bearing rotates under high load, the ball 4 The increase in load and high-speed rotation will generate a large amount of heat, which is transferred to the inside of the support ring 603 through the ball 4, and then conducted to the phase-disguised telescopic block 14. The material of the phase-disguised telescopic block 14 is modified thermoplastic plastic. When heated, the thermoplastic plastic usually expands due to the intensified movement of the molecular chain segments, and shrinks due to the rearrangement of the molecular chains after cooling. Therefore, when the temperature rises, the volume of the phase-disguised telescopic block 14 will expand rapidly, thereby pushing the telescopic top block 13 to move outward, thereby driving the movable block 8 to move to the outside of the limit groove 7, so that it is then abutted against the second groove 5 through the auxiliary roller 9 to assist in supporting the rotation, sharing part of the load of the ball 4 and improving the service life of the bearing.

[0030] The inner wall of the fixed cylinder 12 is provided with a heat conducting sheet 15, and the material of the support ring 603 is beryllium copper alloy. Sealing rings 16 are provided on both sides of the retaining mechanism 6. The sealing ring 16 is arranged in the middle of the outer ring 1 and the inner ring 2. The heat conducting sheet 15 can accelerate the heat conduction effect of the support ring 603 on the disguised telescopic block 14. The support ring 603 is beryllium copper alloy. While the support ring 603 seals the ball 4 to a certain extent, its beryllium copper alloy material itself combines the excellent thermal conductivity of copper and the high strength of beryllium, and has an excellent heat dissipation effect. The sealing ring 16 further improves the sealing of the bearing to prevent external dust from entering the bearing.

[0031] The outer wall of the outer ring 1 is spherical, and a bearing seat 17 is sleeved on the outside of the outer ring 1. The inner wall of the bearing seat 17 is arc-shaped, and the inner wall of the bearing seat 17 matches the outer wall of the outer ring 1. An oil filling groove 18 is provided on one side of the top of the bearing seat 17. The end of the oil filling groove 18 is connected to the inner wall of the bearing seat 17. A sealing cover 19 is provided on the top of the oil filling groove 18. The bearing seat 17 plays the role of connecting, fixing and supporting the outer ring 1 to ensure that it maintains the correct position during operation and provides a self-aligning space. Since the outer wall of the outer ring 1 and the inner wall of the bearing seat 17 are both arc-shaped, the outer ring 1 can be offset and self-aligned inside the bearing seat 17, thereby allowing the bearing to be adjusted slightly at an angle to adapt to the deflection or bending of the shaft. Lubricating oil can be supplemented through the oil filling groove 18 to reduce the friction between the outer ring 1 and the bearing seat 17. The sealing cover 19 plays a sealing role.

[0032] The outer wall of the bearing seat 17 is connected to a heat sink 20, a cooling ventilation pipe 21 is arranged on one side of the bottom of the bearing seat 17, and mounting holes 22 are arranged at the edge of the bearing seat 17. The heat sink 20 improves the heat dissipation capacity of the bearing seat 17 so that it can be cooled quickly. The cooling ventilation pipe 21 can accelerate the cooling effect through natural wind. The bearing seat 17 can be installed in a fixed position by cooperating with the mounting holes 22 and bolts.

[0033] A fixing pin 23 is provided on the inner wall of one side of the inner ring 2. The outer walls of the outer ring 1 and the inner ring 2 are both covered with a wear-resistant layer 24. The material of the wear-resistant layer 24 is a chrome-plated coating. The fixing pin 23 is used to connect the shaft body that needs to be rotated, thereby realizing rotation. The wear-resistant layer 24 improves the overall wear resistance of the bearing.

[0034] A method for using a high-strength outer spherical bearing comprises the following steps: Step 1: embed the inner ring 2 inside the outer ring 1, add a predetermined number of balls 4 to the gap between the outer ring 1 and the inner ring 2, then set the inner ring 2 at the center of the outer ring 1 so that it is in a coaxial position, and evenly set the balls 4 in the first groove 3, and then apply a certain amount of lubricating oil to the position of the balls 4; Step 2: When installing, the first and second half cages 601 and 602 are arranged opposite to each other, and the ball grooves 604 are ensured to cover the outer wall of the ball 4 in sequence, and the first and second half cages 601 and 602 are fixedly connected by rivets 605; Step 3: The bearing seat 17 is sleeved on the outer wall of the outer ring 1. The four ends of the bearing seat 17 are fixedly connected to the mounting holes 22 by bolts, allowing the bearing to be slightly adjusted in angle to adapt to the deflection or bending of the shaft, and a certain amount of lubricating oil is added through the oil filling groove 18; Step 4: When the bearing rotates under high load, the ball 4 will generate a large amount of heat due to the increase in load and high-speed rotation. The heat is transferred to the inside of the support ring 603 through the ball 4, and then conducted to the disguised telescopic block 14. The volume of the disguised telescopic block 14 will expand rapidly when the temperature rises, thereby pushing the telescopic top block 13 to move outward, thereby driving the movable block 8 to move to the outside of the limit groove 7, so that it can then abut against the second groove 5 through the auxiliary roller 9 to assist in supporting the rotation.

[0035] The implementation principle of the embodiment of the present application is as follows: first, the inner ring 2 is embedded in one side of the inner part of the outer ring 1, a predetermined number of balls 4 are added to the gap between the outer ring 1 and the inner ring 2, and then the inner ring 2 is set at the center of the outer ring 1 so that it is in a coaxial position, and the balls 4 are evenly set in the first groove 3, and then a certain amount of lubricating oil is applied to the position of the balls 4. The retaining mechanism 6 can be used to retain multiple groups of balls 4 in position to prevent them from moving at will, and at the same time, the individual balls 4 are separated to prevent them from colliding with each other, thereby reducing wear. When installing, the first and a half retainers 601 and the second The half cage 602 is relatively arranged for installation. During installation, it is ensured that the ball groove 604 can cover the ball 4 in sequence. The outer wall width of the support ring 603 is close to the distance between the outer ring 1 and the inner ring 2, so that it can play a certain dust-proof role without the need for a dust-proof component and improve the support of the bearing. The lifting mechanism 11 can push the movable block 8 to lift it when the ball 4 rotates under high heat and high load, and then the auxiliary roller 9 abuts against the second groove 5 to assist in supporting the rotation. When the bearing rotates under high load, the ball 4 will produce due to the increase in load and high-speed rotation. A large amount of heat is generated, and the heat is transferred to the inside of the support ring 603 through the ball 4, and then conducted to the phase-changing telescopic block 14. The material of the phase-changing telescopic block 14 is modified thermoplastic plastic. When heated, the thermoplastic plastic usually expands due to the intensified movement of the molecular chain segments, and shrinks due to the rearrangement of the molecular chains after cooling. Therefore, when the temperature rises, the volume of the phase-changing telescopic block 14 will expand rapidly, thereby pushing the telescopic top block 13 to move outward, thereby driving the movable block 8 to move outward of the limiting groove 7, so that it is then abutted against the second groove 5 through the auxiliary roller 9 to assist the support Rotation shares part of the load of the ball 4 and improves the service life of the bearing. The bearing seat 17 connects, fixes and supports the outer ring 1 to ensure that it maintains the correct position during operation and provides a self-aligning space. Since the outer wall of the outer ring 1 and the inner wall of the bearing seat 17 are both arc-shaped, the outer ring 1 can be offset and self-aligned inside the bearing seat 17, thereby allowing the bearing to make slight angular adjustments to accommodate the deflection or bending of the shaft. Lubricating oil can be added through the oil filling groove 18 to reduce the friction between the outer ring 1 and the bearing seat 17 and improve the service life of the bearing.
