Description

Technical Field

[0001] This application relates to the field of bearing processing technology, and in particular to an end face support structure for bearing processing. Background Technology

[0002] Bearings are an important component in modern mechanical equipment. Their main function is to support rotating mechanical parts, reduce the coefficient of friction during movement, and ensure rotational accuracy. The bearing cage inside the bearing is a component that limits the movement of the bearing rollers, ensuring even distribution of force and facilitating uniform force distribution on the rollers.

[0003] While existing bearing cages can improve the performance of bearings, the limiting plates on the cages cannot be replaced or repaired. When one or more limiting plates on the cage are damaged, the staff needs to replace the entire cage, resulting in poor maintainability of the cage. Utility Model Content

[0004] This application provides an end face support structure for bearing processing to solve the problem that although existing bearing cages can improve the performance of bearings, the limiting plates on the cage cannot be replaced or repaired. When one or more limiting plates on the cage are damaged, the staff needs to replace the entire cage, resulting in poor maintainability of the cage.

[0005] This application provides an end face support structure for bearing processing, including a first support frame, a second support frame disposed on the outer side of the first support frame; a plurality of limiting plates are disposed between the first support frame and the second support frame, the plurality of limiting plates being arranged in a ring; a third threaded hole is provided on the inner side of each limiting plate, a fixing bolt is threadedly connected to the inner thread of the third threaded hole, a locking washer is slidably connected to one end of the fixing bolt, and a fixing nut is threadedly connected to the fixing bolt near the locking washer.

[0006] Preferably, the first support frame has a first threaded hole near the third threaded hole, and the first threaded hole matches the third threaded hole.

[0007] Preferably, the second support frame has a second bolt hole near the third threaded hole, and the second bolt hole matches the third threaded hole.

[0008] Preferably, there are two of each of the first and second support frames; a connecting plate is provided at the joint of the two first support frames and the two second support frames, and the connecting plate is internally threaded with a connecting bolt.

[0009] Preferably, both the first support frame and the second support frame have mounting grooves on their inner sides.

[0010] Preferably, an oil inlet pipe is connected to the inner side of one of the first support frames, and an oil outlet pipe is connected to the inner side of one of the second support frames.

[0011] Preferably, an inlet pipe is connected to the inner side of one of the first support frames, and an outlet pipe is connected to the inner side of one of the second support frames.

[0012] Beneficial effects:

[0013] While existing bearing cages can improve bearing performance, the limiting plates on the cages cannot be replaced or repaired. When one or more limiting plates on the cage are damaged, the entire cage needs to be replaced, resulting in poor maintainability of the cage.

[0014] When one or more limit plates in this application are damaged, the worker can unscrew the fixing nut from one end of the fixing bolt, then slide the locking washer out from one end of the fixing bolt, and finally unscrew the fixing bolt from the third threaded hole on the inner side of the limit plate. This allows the damaged limit plate to fall between the first support frame and the second support frame, making it convenient for the worker to remove and replace the damaged limit plate. This method allows the worker to individually repair and replace the damaged limit plate in the cage, improving the maintainability of this end face support structure used for bearing processing.

[0031] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings.

[0032] This utility model provides, for example Figures 1-7 The end face support structure for bearing processing shown includes a first support frame 1, and a second support frame 2 is provided on the outer side of the first support frame 1; a plurality of limiting plates 3 are provided between the first support frame 1 and the second support frame 2, and the plurality of limiting plates 3 are arranged in a ring; a third threaded hole 6 is provided on the inner side of each limiting plate 3, and a fixing bolt 7 is threadedly connected inside the third threaded hole 6; a locking washer 8 is slidably connected to one end of the fixing bolt 7, and a fixing nut 9 is threadedly connected to the fixing bolt 7 near the locking washer 8.

[0033] When one or more limit plates 3 on the cage are damaged, the operator can unscrew the fixing nut 9 from one end of the fixing bolt 7, then slide the locking washer 8 out from one end of the fixing bolt 7, and finally unscrew the fixing bolt 7 from the third threaded hole 6 on the inner side of the limit plate 3. This allows the damaged limit plate 3 to fall between the first support frame 1 and the second support frame 2, making it convenient for the operator to remove and replace the damaged limit plate 3. This method allows the operator to individually repair and replace the damaged limit plate 3 in the cage, improving the maintainability of this end face support structure used for bearing processing.

[0034] The first support frame 1 has a first threaded hole 4 near the third threaded hole 6, and the first threaded hole 4 matches the third threaded hole 6.

[0035] The first support frame 1 has a first threaded hole 4, which allows the fixing bolt 7 to fix the first support frame 1 and the limiting plate 3 together.

[0036] The second support frame 2 has a second bolt hole 5 near the third threaded hole 6, and the second bolt hole 5 matches the third threaded hole 6.

[0037] The second bolt hole 5 is provided on the second support frame 2 so that the fixing bolt 7 can fix the limiting plate 3 to the second support frame 2 together.

[0038] Both the first support frame 1 and the second support frame 2 are provided in twos; a connecting plate 10 is provided at the joint of the two first support frames 1 and the two second support frames 2, and a connecting bolt 11 is connected to the internal thread of the connecting plate 10.

[0039] The workers can connect two first support frames 1 and two second support frames 2 together, then place the connecting plate 10 at the connection point and screw in the connecting bolts 11 to fix the two first support frames 1 and two second support frames 2 together. This method facilitates the replacement and repair of any damaged support frames.

[0040] Both the first support frame 1 and the second support frame 2 have mounting grooves 12 on their inner sides.

[0041] The mounting grooves 12 are provided on the inner sides of the first support frame 1 and the second support frame 2 to facilitate the installation of the connecting plate 10 and the connecting bolt 11 in the first support frame 1 and the second support frame 2.

[0042] An oil inlet pipe 13 is connected to the inner side of a first support frame 1, and an oil outlet pipe 14 is connected to the inner side of a second support frame 2.

[0043] The operator can open the valve on the oil inlet pipe 13 to deliver lubricating oil to the bearing, which can improve the bearing's performance. Furthermore, during later maintenance, the operator can open the valve on the oil outlet pipe 14 to allow the oil to be discharged and recycled.

[0044] A liquid inlet pipe 15 is connected to the inner side of a first support frame 1, and a liquid outlet pipe 16 is connected to the inner side of a second support frame 2.

[0045] The system allows workers to open the valves on both the inlet pipe 15 and the outlet pipe 16, allowing cleaning fluid to be pumped into the bearing through the inlet pipe 15 for internal cleaning. The waste fluid can then be discharged through the outlet pipe 16. This method facilitates the cleaning of the bearing's interior.

[0046] Working Principle: When this end-face support structure for bearing processing is in use, if one or more limiting plates 3 on the cage are damaged, the operator can unscrew the fixing nut 9 from one end of the fixing bolt 7, then slide the locking washer 8 out from one end of the fixing bolt 7, and finally unscrew the fixing bolt 7 from the third threaded hole 6 inside the limiting plate 3. This allows the damaged limiting plate 3 to fall between the first support frame 1 and the second support frame 2, making it convenient for the operator to remove and replace the damaged limiting plate 3. This method allows the operator to individually repair and replace the damaged limiting plate 3 in the cage, improving the maintainability of this end-face support structure for bearing processing.

[0047] Furthermore, workers can connect the two first support frames 1 and the two second support frames 2 together, then place the connecting plate 10 at the connection point and screw in the connecting bolts 11 to securely connect the two first support frames 1 and the two second support frames 2 together. This method facilitates the replacement and repair of any damaged support frame, further improving the maintainability of an end-face support structure used for bearing processing.

[0048] Meanwhile, valves are installed on the oil inlet pipe 13, oil outlet pipe 14, liquid inlet pipe 15, and liquid outlet pipe 16. Workers can open the valve on the oil inlet pipe 13 to deliver lubricating oil to the bearing, improving its performance. Furthermore, during later maintenance, workers can open the valve on the oil outlet pipe 14 to drain and recover the oil, and then open the valves on the liquid inlet pipe 15 and the liquid outlet pipe 16 to deliver cleaning fluid into the bearing through the liquid inlet pipe 15, thus cleaning the bearing's interior. The cleaned fluid can then be discharged through the liquid outlet pipe 16. This method facilitates the cleaning of the bearing's interior.
