[0002] A bearing cage is a part used to support and fix bearing elements. It is usually made of metal or plastic. Its main function is to support rolling elements (such as balls or rollers) inside the bearing and keep them in the correct position to ensure that the bearing can operate normally.

[0003] Publication No. CN217633482U discloses a cylindrical roller bearing retainer, belonging to the field of bearing technology, comprising a first outer ring, one side of the first outer ring being fixedly connected to one end corresponding to a mounting post, the other end of the mounting post being mutually engaged with one side corresponding to a second outer ring, the mounting post being provided with a threaded groove, and the mounting post being provided with a slide groove. The cylindrical roller bearing retainer is provided with a fixing post, a threaded groove, a limiting post, a slide groove, and a limiting groove. When the cylindrical roller bearing retainer is installed with the bearing, the fixing post, the limiting post, and the limiting groove are quickly engaged, thereby enabling the first outer ring and the second outer ring to be fixed. When the cylindrical roller is worn or damaged, the operator can easily remove the damaged cylindrical roller from the cylindrical roller bearing retainer, thereby eliminating the need to disassemble the entire cylindrical roller bearing retainer and avoiding the situation where the gap in the cylindrical roller bearing retainer becomes larger.

[0004] The above patent aims to improve the disadvantage that most bearing retainers in the prior art are of one-piece type. When the cylindrical roller is worn or damaged, it is difficult for the operator to remove the damaged cylindrical roller from the retainer. After the entire assembly is disassembled, the gap between the cylindrical roller bearings is likely to increase. This application provides another implementation plan for the problem raised in the above patent. Utility Model Content

[0005] In response to the shortcomings of the existing technology, the utility model provides a phenolic resin bearing retainer, which has the advantage of easy replacement of rollers. It solves the problem that most bearing retainers in the existing technology are one-piece. When the cylindrical roller is worn or damaged, it is difficult for the operator to remove the damaged cylindrical roller from the retainer. After the entire assembly is disassembled, the gap between the cylindrical roller bearings is likely to increase.

[0006] To achieve the above-mentioned object, the present utility model provides the following technical solutions: a phenolic resin bearing retainer, comprising a first bearing retainer ring and a second bearing retainer ring, wherein a retainer splicing mechanism is provided between the first bearing retainer ring and the second bearing retainer ring;

[0007] The retainer splicing mechanism includes a plug-in column fixedly mounted on one side surface of the first bearing retainer ring, a double-conical clamping column fixedly mounted on the bottom of the plug-in column, a plug-in sleeve fixedly mounted on one side surface of the second bearing retainer ring, a rectangular cavity is opened inside the wall of the plug-in sleeve, a spring is fixedly mounted inside the rectangular cavity, and a pin is fixedly mounted on one end of the spring that passes through the inside of the plug-in sleeve.

[0008] Furthermore, the slope of the upper surface of the double-cone clamping column is smaller than the slope of the lower surface of the double-cone clamping column, and the maximum diameter of the double-cone clamping column is adapted to the inner diameter of the plug-in sleeve.

[0009] Furthermore, the number of the rectangular cavities is multiple, the number of the bayonet pins matches the number of the rectangular cavities, and the bayonet pins are evenly distributed inside the plug-in sleeve.

[0010] Furthermore, a limiting ring is fixedly installed on the surface of the first bearing retainer ring, the plug-in column is located on the inner side of the limiting ring, and the inner diameter of the limiting ring is adapted to the outer diameter of the plug-in sleeve.

[0011] Furthermore, a compensating sleeve is fixedly mounted on the surface of the plug-in column, and the outer diameter of the compensating sleeve is adapted to the inner diameter of the plug-in sleeve.

[0012] Furthermore, there are multiple plug-in columns, and the multiple plug-in columns are evenly distributed on the surface of the first bearing retainer ring. There are multiple plug-in sleeves, and the multiple plug-in sleeves are evenly distributed on the surface of the second bearing retainer ring. The number of the plug-in columns matches the number of the plug-in sleeves.

[0013] Compared with the existing technology, the technical solution of this application has the following beneficial effects:

[0014] The phenolic resin bearing retainer is provided with a retainer splicing mechanism between the first bearing retainer ring and the second bearing retainer ring. When in use, the first bearing retainer ring and the second bearing retainer ring can be spliced ​​and assembled together by means of an insert column, a double-tapered clamping column, an insert sleeve and a bayonet. When replacement is required, the first bearing retainer ring and the second bearing retainer ring can be quickly separated, making it easy to remove the rollers on the retainer and replace the rollers. This solves the problem that most bearing retainers in the prior art are of an integrated type, and when the cylindrical rollers are worn or damaged, it is difficult for the operator to remove the damaged cylindrical rollers from the retainer, and after the entire assembly is disassembled, the gap between the cylindrical roller bearings is likely to become larger.

[0019] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0020] See also Figures 1 to 3 In this embodiment, a phenolic resin bearing retainer comprises a first bearing retainer ring 1 and a second bearing retainer ring 2. A retainer splicing mechanism is provided between the first bearing retainer ring 1 and the second bearing retainer ring 2. The retainer splicing mechanism comprises a plug-in column 3 fixedly mounted on the surface of one side of the first bearing retainer ring 1, a double-conical clamping column 4 is fixedly mounted on the bottom of the plug-in column 3, and a plug-in sleeve 5 is fixedly mounted on the surface of one side of the second bearing retainer ring 2. The upper surface slope of the double-conical clamping column 4 is smaller than the lower surface slope of the double-conical clamping column 4. The maximum diameter of the double-conical clamping column 4 is adapted to the inner diameter of the plug-in sleeve 5. A rectangular cavity 6 is opened inside the wall of the plug-in sleeve 5, and a spring 7 is fixedly mounted inside the rectangular cavity 6. A bayonet 8 that penetrates into the interior of the plug-in sleeve 5 is fixedly mounted at one end of the spring 7. There are multiple rectangular cavities 6, and the number of bayonet pins 8 is adapted to the number of rectangular cavities 6. The bayonet pins 8 are evenly distributed inside the plug-in sleeve 5.

[0021] The surface of the first bearing retainer ring 1 is fixedly installed with a limiting ring 9, and the plug-in column 3 is located on the inner side of the limiting ring 9. The inner diameter of the limiting ring 9 is adapted to the outer diameter of the plug-in sleeve 5, which is convenient for clamping the limiting ring 9 on the top of the plug-in sleeve 5, so as to improve the connection stability of the first bearing retainer ring 1 and the second bearing retainer ring 2. A compensation sleeve 10 is fixedly installed on the surface of the plug-in column 3, and the outer diameter of the compensation sleeve 10 is adapted to the inner diameter of the plug-in sleeve 5. The compensation sleeve 10 is convenient for filling the gap between the plug-in column 3 and the plug-in sleeve 5, which is beneficial to prevent the plug-in column 3 from shaking in the plug-in sleeve 5. The number of plug-in columns 3 is multiple, and the multiple plug-in columns 3 are evenly distributed on the surface of the first bearing retainer ring 1. The number of plug-in sleeves 5 is multiple, and the multiple plug-in sleeves 5 are evenly distributed on the surface of the second bearing retainer ring 2. The number of plug-in columns 3 is adapted to the number of plug-in sleeves 5.

[0022] It should be noted that the latch 8 and the rectangular cavity 6 in this embodiment are in sliding contact.

[0023] It should be noted that the top and bottom shapes of the double-conical clamping column 4 in this embodiment are both conical.

[0024] The working principle of the above embodiment is:

[0025] When in use, insert the plug-in column 3 and the double-conical clamping column 4 into the plug-in sleeve 5, and push the pin 8 into the rectangular cavity 6 through the bottom of the double-conical clamping column 4. At this time, the spring 7 is compressed until the pin 8 is located above the double-conical clamping column 4. At this time, the spring 7 pushes the pin 8 out of the rectangular cavity 6, so that the pin 8 can block the double-conical clamping column 4. At this time, the compensation sleeve 10 is inserted into the inner side of the plug-in sleeve 5, and the limit ring 9 is sleeved on the outside of the plug-in sleeve 5, and the assembly and splicing of the first bearing retainer ring 1 and the second bearing retainer ring 2 can be completed. When disassembly is required, the first bearing retainer ring 1 is pulled up with force. Since the top surface of the double-conical clamping column 4 is a slope with a smaller slope, the double-conical clamping column 4 can only be pulled out from under the pin 8 by force.
