DETAILED DESCRIPTION

[0021] The technical solution of this patent is further described in detail below in conjunction with specific implementation methods.

[0022] like Figure 1-4 As shown, the utility model provides a technical solution: a bearing retainer with good wear resistance, including a fixing ring 1, six groups of positioning blocks 2 are fixedly installed at equal angles on one side of the fixing ring 1, an oil storage tank 3 is provided inside the positioning block 2, and multiple groups of oil outlet holes 4 are equidistantly provided on both sides of the positioning block 2, and the oil outlet holes 4 are connected with the oil storage tank 3. By providing the oil outlet holes 4, when the roller 27 rolls on both sides of the positioning block 2, the lubricating oil in the oil storage tank 3 can flow from the oil outlet holes 4 to the surface of the roller 27, thereby reducing the friction between the roller 27 and the bearing components.

[0023] The fixing ring 1 is located on one side of the positioning block 2 and three groups of positioning blocks 5 and positioning blocks 3 8 are fixedly installed at equal angles. A connecting plug plate 6 is fixedly installed on one side of the positioning block 2, and the connecting plug plate 6 corresponds to the connecting slot 10. Because the connecting plug plate 6 and the connecting slot 10 are provided, after the connecting plug plate 6 is inserted into the corresponding connecting slot 10, it is ensured that the two groups of fixing rings 1 are clamped on both sides of the roller 27 for connection and fixing without misalignment and deflection;

[0024] The surface of the connecting plug plate 6 is provided with a fixing hole 7, and the fixing hole 7 corresponds to the fixing plug rod 11. The inside of the positioning block 3 8 away from the side of the fixing ring 1 is provided with a mounting groove 9, and the side of the fixing ring 1 is provided with a connecting slot 10 at the bottom of the mounting groove 9, and the mounting groove 9 is slidably installed with a fixing plug rod 11, and the fixing plug rod 11 runs through both ends of the mounting groove 9. Because the fixing hole 7 and the fixing plug rod 11 are provided, after the fixing plug rod 11 is inserted into the corresponding fixing hole 7, the connecting plug plate 6 is clamped and fixed in the corresponding connecting slot 10, thereby ensuring that the two sets of fixing rings 1 can be connected and fixed.

[0025] A fixed plug rod 11 is located on a side surface of the installation slot 19 close to the connecting slot 10, and a fixed spring 13 is provided on the surface of the fixed plug rod 11 located inside the installation slot 19. A sliding top plate 14 is slidably installed on the top of the positioning block 38, and a clamping block 15 is fixedly installed on the top of the fixed plug rod 11 at the bottom of the sliding top plate 14, and the clamping block 15 is slidably connected with the sliding top plate 14. By providing a fixed spring 13, the fixed plug rod 11 is pressed down and extends out of the installation slot 19 under the rebound action of the fixed spring 13, and is inserted into the fixed plug hole 7 corresponding to the connecting plug plate 6 inside the connecting slot 10;

[0026] The inside of the positioning block 3 8 is provided with a mounting groove 2 16 on the side away from the connecting slot 10, and the inside of the mounting groove 2 16 is symmetrically fixed with slide bars 17, and the surfaces of the two sets of slide bars 17 are slidably installed with slide seats 18, and the surface of the slide bars 17 is provided with a return spring 19 on the side of the slide seat 18. Because the return spring 19 is provided, the slide seat 18 is pushed to the side away from the fixed inclined block 21 under the rebound action of the return spring 19, and the control block 15 slides at the bottom of the sliding top plate 14;

[0027] The positioning block 3 8 is located at the top of the mounting groove 2 16 and is provided with a mounting groove 3 20, and a fixed oblique block 21 is fixedly installed on one side of the bottom of the mounting groove 3 20. A sliding oblique block 22 is fixedly installed on one side of the bottom of the sliding top plate 14 located inside the mounting groove 3 20, and the sliding oblique block 22 is fitted with the fixed oblique block 21. Through the fixed oblique block 21 and the sliding oblique block 22, the sliding oblique block 22 is controlled to move close to the top of the fixed oblique block 21, so that the sliding top plate 14 can move away from or close to the positioning block 3 8, thereby controlling the fixed insertion rod 11 to retract or extend out of the mounting groove 1 9.

[0028] A card plate 23 is symmetrically and slidably installed inside the sliding bevel block 22, and a moving rod 24 is fixedly installed at the bottom of the card plate 23. The bottom end of the moving rod 24 passes through the sliding bevel block 22 and extends to the inside of the return spring 19 and is fixedly connected to the slide seat 18. Because of the moving rod 24, when the sliding top plate 14 moves up and down, the sliding bevel block 22 slides up and down on the surfaces of the two groups of moving rods 24, ensuring that the sliding bevel block 22 will not tilt or deflect during the movement.

[0029] A fixing plate 25 is fixedly installed at one end of the sliding top plate 14 close to the fixing ring 1, and two sets of fixing bolts 26 are provided on the top of the fixing plate 25. The fixing bolts 26 pass through the fixing plate 25 and are connected to the fixing ring 1 and the positioning block three 8. By screwing the fixing bolts 26 to connect with the fixing ring 1 and the positioning block three 8, the sliding top plate 14 is clamped and fixed at the top of the positioning block three 8.

[0030] The working principle of the utility model is:

[0031] After injecting a proper amount of lubricating oil into the oil storage tank 3, place the fixing ring 1 horizontally on the top of the table, loosen the fixing bolts 26, push the sliding top plate 14 to make the sliding inclined block 22 fit the inclined surface of the fixed inclined block 21 and move, so that the sliding top plate 14 is away from the positioning block 3 8, and at the same time, the clamping block 15 slides at the bottom of the sliding top plate 14 to lift the fixed plug rod 11 and retract it into the installation groove 1 9, tighten a set of fixing bolts 26 to connect the fixing plate 25 with the positioning block 3 8, repeat the steps, and clamp the roller 27 into the top of the fixing ring 1 between the adjacent positioning blocks 1 2, 2 5 and 3 8, and then take another The fixed rod 11 of the group is retracted into the fixing ring 1 inside the installation groove 9 to cover the top of the roller 27, so that the relative positioning blocks 25 and 38 of the two groups of fixing rings 1 are inserted alternately until the fixing hole 7 corresponds to the fixed rod 11, and the fixing bolt 26 is loosened. Under the rebound action of the reset spring 19 and the fixing spring 13, the sliding top plate 14 is pushed toward the fixing ring 1, and at the same time, the fixing rod 11 is pushed out of the installation groove 9 and inserted into the corresponding fixing hole 7, and the fixing bolt 26 is tightened to connect the fixing plate 25 with the positioning block 3 8 and the fixing ring 1, so that the two groups of fixing rings 1 are clamped and fixed on both sides of the roller 27.
