Description

Technical Field

[0001] The invention relates to the technical field of bearing assembly, and in particular to a high-damping silent bearing and an assembly production line thereof. Background Art

[0002] In the operation of modern industrial machinery, bearing accessories play an extremely critical role. With the development of various types of mechanical equipment towards high speed and high precision, the requirements for bearing accessories are becoming increasingly stringent. When traditional bearing accessories run at high speed, they often produce large noise due to the limitations of internal structure design and manufacturing process, which not only affects the stability of equipment operation, but also causes noise pollution in the working environment and reduces the service life of the equipment. It is worth noting that the assembly of plastic bearings in the existing technology mainly relies on manual operation. There are many disadvantages in the manual assembly method. It is inefficient and difficult to meet the needs of large-scale production. In addition, it is difficult to ensure the precise coordination of various components during the assembly process, which further aggravates the performance problems of bearings when running at high speeds.

[0003] The existing patent CN108248049B discloses a bearing assembly production line for assembling plastic bearings, and the bearing assembly production line includes: a bearing component loader, including a frame positioning seat for carrying a fixing frame and a retaining frame of a bearing assembly, a shaft ring positioning seat for carrying a shaft ring of the bearing assembly, and a bottom ring positioning seat for carrying a bottom ring of the bearing assembly; a bearing hot welding machine, including a hot welding loading seat and a hot melt component for positioning the bearing assembly, the hot melt component is arranged above the hot welding loading seat, and the hot melt component has a hot melt head for welding the bearing assembly located on the hot welding loading seat; wherein the bearing hot welding machine is arranged on one side of the bearing component loader, so that a first robot located between the bearing component loader and the bearing hot welding machine grabs the fixing frame, retaining frame, shaft ring and bottom ring located on the bearing component loader to the bearing hot welding machine for assembly hot welding, which solves the problem of low assembly efficiency of plastic bearings in the prior art.

[0004] However, in actual use, it was found that there would be a lot of excess beads during manual assembly. In the process of taking the beads, the beads would collide with each other and wear out, and the retaining frame would be easily deformed by pressure during manual taking, and sometimes there would be problems of beads leaking or loose assembly of the beads. At the same time, the existing assembly production line does not have a staggered installation of solid balls and hollow balls. The use of solid balls and hollow balls can effectively reduce the centrifugal force of the balls at high speeds, reduce wear and reduce the noise generated. Summary of the invention

[0005] The purpose of the present invention is to address the deficiencies in the prior art and to provide an assembly production line, which solves the problem of easy wear during manual operation by setting up a supporting mechanism and driving the retaining frame to alternately install solid balls and hollow balls with the assistance of a ball feeding mechanism, and reduces the wear and noise problems of the bearings at high speeds through the hollow balls.

[0071] (2) The present invention innovatively sets a support mechanism to drive the cage to rotate continuously during its movement, thereby staggeredly arranging solid balls and hollow balls on the cage. In this way, when the cage is running at a high speed, the centrifugal force on the balls can be effectively reduced, thereby reducing the degree of ball wear and the noise level.

[0072] (3) The present invention ingeniously constructs a ball feeding mechanism, in which the lower ball assembly can automatically and continuously supply solid balls and hollow balls for the filling process, thereby avoiding the situation of missing balls after the cage is filled with balls. At the same time, the specially equipped bead replenishing assembly can accurately locate and fill the balls that are missing from the cage due to unexpected circumstances with the cooperation of the detection mechanism, ensuring that the cage is finally in a state of being fully loaded with balls, thereby avoiding the occurrence of ball leakage.

[0073] (4) The present invention has a carefully designed ball lifting assembly, which can simultaneously lift the balls in the lower ball assembly and the balls in the replenishing ball assembly, effectively assisting the supporting mechanism in carrying out the ball installation work of the retaining frame, thereby achieving an efficient ball batch loading operation mode and improving the overall work efficiency.

[0074] (5) The present invention reasonably sets up a detection mechanism, which can accurately determine whether there are balls in the cage and apply appropriate pressure to the balls loaded on the cage, so that the balls are firmly embedded in the cage and effectively prevent the balls from falling off. In addition, once the detection mechanism detects the position of the missing balls, it can cooperate with the bead replenishing component to perform precise bead replenishing operations on the corresponding position, ensuring that the cage will not leak balls during the process of loading balls.

[0075] In summary, the present invention has the advantages of reducing the centrifugal force of the balls at high speeds, effectively reducing wear and noise, and avoiding problems such as ball shortage and ball leakage. BRIEF DESCRIPTION OF THE DRAWINGS

[0104] Embodiment 1

[0105] like Figure 8 and Figures 19 to 20 As shown, this embodiment provides a high damping silent bearing, including a retaining frame 100 and solid balls 200 and hollow balls 300 staggeredly installed on the retaining frame 100, and the retaining frame 100 is provided with an oil storage cavity 400, an oil guide groove 500 and an oil inlet hole 600.

[0106] In this embodiment, by staggeredly installing solid balls 200 and hollow balls 300 on the retaining frame 100, the solid balls 200 can ensure the supporting strength of the bearing, and the proper installation of the hollow balls 300 can reduce the centrifugal force of the bearing at high speeds, thereby reducing the wear of the balls and reducing the noise generated by the balls. By providing an oil storage chamber 400, an oil guide groove 500 and an oil inlet hole 600, sufficient lubricating oil is provided to the balls, reducing the friction of the balls inside the bearing, thereby achieving the effect of reducing the noise when the bearing rotates at high speed.

[0107] In detail, after the solid balls 200 and the hollow balls 300 are staggeredly installed on the retaining frame 100, the lubricating oil is injected into the oil storage chamber 400 through the oil inlet hole 600 and stored. When the balls rotate on the retaining frame 100, the lubricating oil in the oil storage chamber 400 is applied to the surface of each ball on the retaining frame 100 through the oil guide groove 500, thereby reducing the friction of the balls inside the bearing, thereby reducing the noise during the operation of the bearing.

[0108] It should be noted that the oil guide groove 500 is arranged at the position where each ball on the retaining frame 100 contacts the retaining frame 100, and the oil storage cavity 400 is an annular cavity. When the bearing is running, the rotation of the ball drives the lubricating oil in the oil guide groove 500 to smear the surface of the ball to lubricate the ball.

[0109] Embodiment 2

[0110] like Figures 1 to 3 and Figure 8 As shown, an assembly production line is used to form a high damping silent bearing of embodiment 1, comprising:

[0111] A supporting mechanism 1, the supporting mechanism 1 is used to drive the retaining frame 100 thereon to staggeredly install the solid balls 200 and the hollow balls 300;

[0112] A ball feeding mechanism 2, which is disposed on one side of the supporting mechanism 1 and is used to provide the solid balls 200 and the hollow balls 300 and assist the supporting mechanism 1 in staggered installation of the solid balls 200 and the hollow balls 300;

[0113] A detection mechanism 3, which is disposed on the supporting mechanism 1 and is used to detect whether the retaining frame 100 leaks balls and to press the balls on the retaining frame 100;

[0114] The supporting mechanism 1 comprises:

[0115] A translation assembly 11, the translation assembly 11 is used to drive the retaining frame 100 to translate to install a plurality of balls;

[0116] A limiting assembly 12, which is disposed on the translation assembly 11 and is used to preliminarily limit the position of the retaining frame 100 for subsequent fixing operations;

[0117] A transmission assembly 13, the transmission assembly 13 is disposed on the translation assembly 11 and is used to drive the retaining frame 100 to rotate so as to install the balls at different positions;

[0118] The fixing assembly 14 is disposed on the limiting assembly 12 and is used to fix the retaining frame 100 .

[0119] In this embodiment, by providing a supporting mechanism 1 and a ball feeding mechanism 2, the retaining frame 100 can be staggeredly installed with solid balls 200 and hollow balls 300. The hollow balls 300 reduce the centrifugal force of the bearing at high speeds, thereby reducing the wear and noise of the balls at high speeds. The detection mechanism 3 is used to detect the position of the leaking beads, and the retaining frame 100 is operated to replenish the beads, thereby avoiding the problem of the retaining frame 100 leaking beads.

[0120] In detail, first, the retaining frame 100 is fixed to the supporting mechanism 1 by the fixing component 14, and the retaining frame 100 is driven to translate and rotate at the same time by the translation component 11 and the transmission component 13, and with the cooperation of the ball feeding mechanism 2, the retaining frame 100 is sequentially installed with the solid balls 200 and the hollow balls 300 staggered on the ball feeding mechanism 2. During the process of loading the balls on the retaining frame 100, the detection mechanism 3 detects whether the balls are installed on the retaining frame 100. The positions on the retaining frame 100 where the balls are not installed due to accidents will be recorded, and the ball replenishing operation will be performed at the end.

[0121] It should be noted that the retaining frame 100 is made of plastic, has 16 holes for installing balls, and has a structure inside the retaining frame 100 for the balls to abut against, so as to prevent the balls from being installed too far.

[0122] Further, if Figure 4 As shown, the translation assembly 11 includes:

[0123] Base 111;

[0124] Sliding rods 112, two groups of the sliding rods 112 are disposed on the base 111;

[0125] A driving motor 113, wherein the driving motor 113 is installed on the base 111;

[0126] A screw rod 114, wherein the screw rod 114 is drivingly connected to an output end of the drive motor 113;

[0127] A thread sleeve 115, wherein the thread sleeve 115 is sleeved on the slide rod 112, and the thread sleeve 115 and the screw rod 114 are engaged with each other through threads for transmission;

[0128] The vertical plate 116 is disposed on the wire sleeve 115 and is connected to the wire sleeve 115 through reinforcement ribs.

[0129] In this embodiment, by providing a translation assembly 11 , the retaining frame 100 can be translated on the ball feeding mechanism 2 to install the balls at different positions on the ball feeding mechanism 2 .

[0130] In detail, the lead screw 114 is driven by the driving motor 113, and the lead screw 114 drives the threaded sleeve 115 to slide on the slide bar 112, thereby driving the retaining frame 100 installed on the supporting mechanism 1 to translate, so as to install the balls at different positions on the ball feeding mechanism 2.

[0131] Further, if Figure 7 and Fig. 9 As shown, the limiting assembly 12 includes:

[0132] A top plate 121, wherein the top plate 121 is disposed on the vertical plate 116 and connected to the vertical plate 116 by reinforcing ribs;

[0133] A support plate 122, wherein the support plate 122 is disposed at the bottom of the top plate 121;

[0134] a limiting plate 123, the limiting plate 123 is rotatably disposed on the supporting plate 122 and is used to limit the position of the retaining frame 100;

[0135] The protrusion 124 is disposed on the limiting plate 123 and is used to assist the retaining frame 100 in being installed on the limiting plate 123 .

[0136] In this embodiment, by providing the limiting assembly 12, it is convenient for the operator to install the retaining frame 100 on the supporting mechanism 1, and first define the position of the retaining frame 100 on the supporting mechanism 1, so that the subsequent fixing assembly 14 can fix the retaining frame 100.

[0137] In detail, the operator firstly points the hole for installing the ball on the retaining frame 100 upwards, and then pushes the retaining frame 100 toward the side of the limit plate 123 along the inclined surface of the protrusion 124. Finally, the retaining frame 100 abuts against the side of the limit plate 123. The part of the protrusion 124 close to the limit plate 123 is in close contact with the retaining frame 100 to provide initial support for the retaining frame 100. Subsequently, the retaining frame 100 is further supported and fixed by the fixing assembly 14 to prevent the retaining frame 100 and the limit plate 123 from sliding relative to each other.

[0138] Further, if Figure 5 to Figure 6 As shown, the transmission assembly 13 includes:

[0139] A stepper motor 131, wherein the stepper motor 131 is mounted on the vertical plate 116;

[0140] A first driving tooth 132, wherein the first driving tooth 132 is drivingly connected to an output end of the stepping motor 131;

[0141] A first driven tooth 133, wherein the first driven tooth 133 is meshed with the first driving tooth 132 for transmission;

[0142] a transmission shaft 134 , the transmission shaft 134 being transmission-connected to the first driven gear 133 and passing through the vertical plate 116 ;

[0143] A second driving tooth 135 , wherein the second driving tooth 135 is disposed on the transmission shaft 134 ;

[0144] A second driven tooth 136, wherein the second driven tooth 136 is meshed with the second driving tooth 135 for transmission;

[0145] The transmission rod 137 is transmission-connected with the second driven tooth 136 , and the transmission rod 137 passes through the support plate 122 and the limit plate 123 .

[0146] In this embodiment, by setting the transmission component 13 to cooperate with the translation component 11, the retaining frame 100 rotates during translation, and the balls on the ball feeding mechanism 2 are installed at different positions of the retaining frame 100 to achieve the effect of staggered installation of solid balls 200 and hollow balls 300.

[0147] In detail, the first driving tooth 132 is driven by the stepping motor 131 to drive the first driven tooth 133 to rotate, and the power is transmitted through the transmission shaft 134. The second driving tooth 135 on the transmission shaft 134 drives the second driven tooth 136 to rotate, and the second driven tooth 136 finally drives the transmission rod 137 to rotate.

[0148] It should be noted that the gear thickness of the first driving tooth 132 is smaller than the gear thickness of the first driven tooth 133 in order to cooperate with the fixing component 14 to fix the retaining frame 100. Multiple sets of gears are used to drive the retaining frame 100 to rotate instead of directly driving the retaining frame 100 to rotate in order to avoid the position interference during the installation of the retaining frame 100, which may cause the retaining frame 100 to be unable to be installed on the supporting mechanism 1.

[0149] Further, if Figure 6 and Figures 9 to 11 As shown, the fixing assembly 14 includes:

[0150] Cylinder A141, the cylinder A141 is installed on the vertical plate 116;

[0151] A clamping block 142, wherein the clamping block 142 is arranged on the top rod of the cylinder A141;

[0152] A clamping plate 143, wherein the clamping plate 143 is disposed on both sides of the second driving tooth 135;

[0153] A connecting plate 144, wherein the connecting plate 144 is rotatably connected to the transmission rod 137;

[0154] A fixing block 145, wherein the fixing block 145 is disposed on the limiting plate 123;

[0155] The fixed arc plate 146 is inserted into the interior of the fixed block 145 .

[0156] In this embodiment, by providing a fixing component 14, on the one hand, the internal support circle of the retaining frame 100 can be fixed to prevent the problem of the inability to complete the work of filling the balls due to the change of the position of the retaining frame 100. The advantage is that the force inside the retaining frame 100 is uniform. During the process of filling the balls in the retaining frame 100, the problem of pressing the retaining frame 100 and causing the retaining frame 100 to be deformed will not occur as in manual operation. On the other hand, the fixing component 14 also cooperates with the transmission component 13, and the power provided by the transmission component 13 simultaneously drives the limit plate 123 and the retaining frame 100 to rotate.

[0157] In detail, the cylinder A141 drives the clamping block 142 to move, which in turn drives the first driven tooth 133 to move, and then the transmission shaft 134 moves and drives the second driven tooth 136 to move through the clamping plate 143, and the second driven tooth 136 drives the transmission rod 137 to move, and the transmission rod 137 drives the fixed arc plate 146 to expand outward by pulling the connecting plate 144 to support and fix the retaining frame 100, and drives the limit plate 123 to rotate with the retaining frame 100 through the fixed block 145 on the limit plate 123.

[0158] It should be noted that the curvature of the contact portion between the fixed arc plate 146 and the retainer 100 is the same as the curvature of the inner ring of the retainer 100 , so as to ensure uniform force inside the retainer 100 .

[0159] Further, if Figure 12 to Figure 13 As shown, the bead feeding mechanism 2 comprises:

[0160] A lower ball assembly 21, the lower ball assembly 21 is used to automatically and continuously convey the solid balls 200 and the hollow balls 300;

[0161] A bead supplement component 22, which is disposed on the lower bead component 21 and is used to supplement the balls that are missing from the retaining frame 100;

[0162] The ball lifting assembly 23 is disposed at the bottom of the lower ball assembly 21 and is used to lift the ball so that the retaining frame 100 can install the ball.

[0163] In this embodiment, by providing the lower bead assembly 21 and the replenishing bead assembly 22 in the bead feeding mechanism 2, the balls can be automatically and continuously replenished, and with the cooperation of the ball lifting assembly 23, the balls in the lower bead assembly 21 and the replenishing bead assembly 22 are lifted for installation on the retaining frame 100 on the supporting mechanism 1, wherein the replenishing bead assembly 22 also cooperates with the detection mechanism 3 to accurately replenish the positions of the missing beads on the retaining frame 100 to ensure that each hole position of the retaining frame 100 is filled with balls.

[0164] In detail, the lower ball assembly 21 staggers the solid balls 200 and the hollow balls 300 so that the retaining frame 100 can be installed with the solid balls 200 and the hollow balls 300, and realizes automatic replenishment of the balls after the retaining frame 100 is filled, thereby avoiding the problem of missing balls. In conjunction with the position of the leaked balls detected during the filling process in the detection mechanism 3, the bead replenishing assembly 22 will replenish the holes of the leaked balls on the retaining frame 100 with solid balls 200 or hollow balls 300 to avoid the occurrence of leaked balls.

[0165] Further, if Figure 12 to Figure 14 As shown, the lower bead assembly 21 includes:

[0166] A platform 211, on which a slide groove and a plurality of through grooves for rolling balls are provided;

[0167] A mounting plate 212, wherein the mounting plate 212 is disposed on the platform 211;

[0168] A solid bead box 213, wherein the solid bead box 213 is arranged on the mounting plate 212 through a fastener;

[0169] A hollow bead box 214, wherein the hollow bead box 214 is disposed on one side of the solid bead box 213;

[0170] A lower bead tube A215, wherein the lower bead tube A215 is connected to the bottom of the solid bead box 213;

[0171] The lower bead tube B216 is connected to the bottom of the hollow bead box 214.

[0172] In this embodiment, by setting the lower ball assembly 21, solid balls 200 and hollow balls 300 are alternately set. When the retaining frame 100 is filled with balls, solid balls 200 and hollow balls 300 are alternately filled on the retaining frame 100. While the solid balls 200 ensure the support of the bearing, the proper filling of hollow balls 300 can reduce the overall centrifugal force of the balls under high speed conditions, thereby reducing the wear and noise of the balls. When the balls are filled with the retaining frame 100, new balls are automatically added, and the balls are fed in sequence without large relative movement, and the wear between the balls is small.

[0173] In detail, the solid balls 200 in the solid ball box 213 roll down the lower ball tube A215 to the slideway on the platform 211 where the solid balls 200 are placed, and the hollow balls 300 in the hollow ball box 214 roll down the lower ball tube B216 to the slideway on the platform 211 where the hollow balls 300 are placed. When the balls on the platform 211 are loaded by the retaining frame 100, the balls in the solid ball box 213 and the hollow ball box 214 will continue to fall onto the platform 211 for replenishment.

[0174] It should be noted that the platform 211 is staggered with slide grooves for the solid balls 200 and the hollow balls 300 to roll. When the slide grooves are full of balls, some of the balls are just above the internal grooves of the platform 211, so that the ball lifting assembly 23 can lift the balls to assist the supporting mechanism 1 to install the balls on the retaining frame 100.

[0175] Further, if Figures 15 to 17 As shown, the bead filling assembly 22 includes:

[0176] A bead filling rod 221, wherein the bead filling rod 221 is inserted into the interior of the lifting plate 234;

[0177] Spring A222, the spring A222 is sleeved on the bead filling rod 221.

[0178] In this embodiment, by providing the bead replenishing assembly 22, when the detection mechanism 3 detects the position of the missing beads on the retaining frame 100, the bead replenishing assembly 22 replenishes the position of the missing beads on the retaining frame 100, ensuring that the retaining frame 100 is completely filled with balls, avoiding the problem of missing beads due to unexpected circumstances where the beads are not installed in place.

[0179] In detail, when the supporting mechanism 1 drives the retaining frame 100 to move to the position of the bead replenishing assembly 22, the retaining frame 100 is rotated so that the hole position of the leaking bead is facing downward, and the ball lifting assembly 23 lifts the ball at the bead replenishing assembly 22 and installs it to the position of the leaking bead. Since there are multiple groups of retaining frames 100, some retaining frames 100 may not have the problem of bead leakage at this hole position. The balls in the retaining frames 100 with leaking beads will squeeze the balls on the bead replenishing rod 221, driving the bead replenishing rod 221 to move downward, and at the same time, the spring A222 contracts, and the retaining frame 100 with leaking beads will be installed with balls, thus completing a bead replenishing operation. If beads are leaking at different positions of multiple different retaining frames 100 at the same time, multiple bead replenishing operations are required, and solid balls 200 or hollow balls 300 need to be selected according to the leaking bead position.

[0180] It should be noted that the bead replenishing assembly 22 is respectively arranged on the slideways of the solid ball 200 and the hollow ball 300 on the platform 211, and the solid ball 200 or the hollow ball 300 can be replenished according to the type of missing balls in the retaining frame 100. A disc for limiting is provided at the bottom of the bead replenishing rod 221.

[0181] Further, if Figure 12 to Figure 13 and Fig.15 As shown, the bead lifting assembly 23 includes:

[0182] A fixing rod 231, wherein the fixing rod 231 is disposed at the bottom of the platform 211;

[0183] A bottom plate 232, the bottom plate 232 is disposed at the bottom end of the fixing rod 231;

[0184] A cylinder B233, wherein the cylinder B233 is installed on the base plate 232;

[0185] A lifting plate 234, wherein the lifting plate 234 is inserted on the fixing rod 231;

[0186] The bead lifting rod 235 is disposed on the lifting plate 234 .

[0187] In this embodiment, the ball lifting assembly 23 is provided to cooperate with the lower ball assembly 21 to lift the balls for the retaining frame 100 to be loaded with balls, and the ball replenishing assembly 22 is cooperated to lift the balls to replenish the positions of the missing balls on the retaining frame 100.

[0188] In detail, the cylinder B233 can control the lifting plate 234 to slide on the fixed rod 231. When the ball needs to be lifted, the cylinder B233 controls the lifting plate 234 to move upward. The ball lifting rod 235 on the lifting plate 234 drives some of the balls on the platform 211 to rise. The lifting plate 234 drives the bead replenishing rod 221 to move upward through the spring A222, thereby driving the balls to rise.

[0189] It should be noted that the tops of the bead lifting rod 235 and the bead replenishing rod 221 are arc-shaped to fit the ball.

[0190] Embodiment 3

[0191] like Fig.18 As shown, the detection mechanism 3 includes:

[0192] A telescopic rod 301, wherein the telescopic rod 301 is disposed at the bottom of the top plate 121;

[0193] A circular plate 302, wherein the circular plate 302 is disposed on the top rod of the telescopic rod 301;

[0194] A spring B303, wherein the spring B303 is sleeved on the telescopic rod 301;

[0195] A pressure sensor 304, wherein the pressure sensor 304 is disposed on the circular plate 302;

[0196] The pressing block 305 is disposed on the pressure sensor 304 .

[0197] In this embodiment, by setting up the detection mechanism 3, on the one hand, during the process of loading the balls on the retaining frame 100, it can be detected whether the mounting holes of the retaining frame 100 are installed with balls. If there are no balls at the corresponding holes, the position of the holes and the type of balls corresponding to the positions are recorded, and the ball replenishment operation is performed on the positions where the beads on the retaining frame 100 are missing in cooperation with the ball replenishment assembly 22. On the other hand, the detection mechanism 3 can press the balls that are not firmly installed on the retaining frame 100 to ensure that the balls are firmly installed on the retaining frame 100.

[0198] In detail, when there is a ball on the retaining frame 100, the ball will be squeezed by the clamping block 305, and drive the telescopic rod 301 and the spring B303 to contract, so that the ball is firmly installed on the retaining frame 100. At this time, the pressure sensor 304 detects the pressure change side, indicating that a ball is installed in this hole on the retaining frame 100, otherwise not.

[0199] It should be noted that the pressure sensor 304 is a tension-compression pressure sensor, which can detect the magnitude of the tension or pressure.

[0200] Working process

[0201] During the entire process of loading the retaining frame 100 with balls, the retaining frame 100 is first installed on the supporting mechanism 1 and fixed by the fixing assembly 14, and then the translation assembly 11 and the transmission assembly 13 drive the retaining frame 100 to translate and rotate, and the balls are installed at different positions of the retaining frame 100. At the same time, the ball lifting assembly 23 in the ball feeding mechanism 2 lifts the solid balls 200 and the hollow balls 300 in the lower ball assembly 21 so that the retaining frame 100 can alternately install the solid balls 200 and the hollow balls 300. During this process, the detection mechanism 3 will detect whether the balls are installed on the retaining frame 100. If the corresponding hole position on the retaining frame 100 is not installed with a ball, the position of the hole position and the type of ball required for the hole position will be recorded. Finally, the ball replenishing operation is performed on the position of the missing beads on the retaining frame 100 through the ball replenishing assembly 22 to ensure that all holes of the retaining frame 100 are installed with balls.

[0202] After staggeredly installing the solid balls 200 and the hollow balls 300 on the retaining frame 100, the operator injects lubricating oil into the oil storage chamber 400 through the oil inlet hole 600. When the bearing rotates at high speed, the balls will also rotate and drive the lubricating oil in the oil guide groove 500 to be smeared on the surface of the balls, lubricating the balls, and reducing the friction of the balls inside the bearing to reduce the noise when the bearing rotates at high speed. Finally, the operator installs the retaining frame 100 with balls and lubricating oil between the outer ring and the inner ring of the bearing through other assembly production lines, and finally seals the bearing to block the oil inlet hole 600 on the retaining frame 100 to prevent leakage of lubricating oil.

[0203] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
