Technical Field

[0001] The utility model relates to the field of standard bearings, especially to environment-friendly oil-free lubricating bearings. Background Art

[0002] An environment-friendly oil-free lubricating bearing is a bearing that reduces or eliminates the need for traditional lubricating oil through special design and material selection. Through its unique design and materials, the environment-friendly oil-free lubricating bearing can not only improve the operation efficiency of equipment, but also reduce the impact on the environment, meeting the requirements of modern industry for environmental protection.

[0003] In the field of modern industry, as a key mechanical component, the performance and reliability of bearings directly affect the operation efficiency and service life of various mechanical equipment.

[0004] There are some deficiencies in the existing environment-friendly oil-free lubricating bearings: on the one hand, when many bearings are used in special machinery, two or more sets of bearings may be used for splicing to improve the running stability of the machinery. However, when the existing bearings are spliced, most of them only smear grease on their surfaces for splicing, and this splicing method has poor stability and may cause slight deviations. On the other hand, traditional designs are difficult to achieve rapid and non-destructive disassembly. The prying method with special tools easily damages the structural integrity of the sealing piece and reduces the sealing effect, thus affecting the service life and performance stability of the bearing. Therefore, an environment-friendly oil-free lubricating bearing is proposed to solve the above problems. Content of the Utility Model

[0005] To make up for the above deficiencies, the utility model provides an environment-friendly oil-free lubricating bearing, aiming to improve the problem that when the existing bearings are spliced, most of them only smear grease on their surfaces for splicing, and this splicing method has poor stability.

[0007] A sliding rod is slidably connected to the inner wall of the fixed rod, the top end of the outer wall of the sliding rod is rotatably connected to a rotating block, the central axis of rotation of the rotating block is fixedly connected to a hinged rod, the bottom end of the hinged rod is hinged to two hinged rods, and the ends of the two hinged rods away from the connecting rod are hinged to a wedge block. The two wedge blocks are elastically connected by a limiting spring.

[0008] As a further description of the above technical solution:

[0009] The quick-release component includes a sealing piece, and two sets of upper and lower sliders are slidably connected to the inner wall of the sealing piece. The two sides of each slider penetrate and are slidably connected with a clamping block, and the two clamping blocks are elastically connected by a return spring. A positioning block is fixedly connected to the outer wall of the slider.

[0010] As a further description of the above technical solution:

[0011] The fixed rod is rotatably connected to the inner wall of the cavity on the surface of the shaft body. Positioning grooves are formed on both sides of the inner wall of the cavity of the shaft body, and the wedge block is clamped with the inner wall of the positioning groove.

[0012] As a further description of the above technical solution:

[0013] The two wedge blocks penetrate and are slidably connected to the inner wall of the top end of the sliding rod, and the hinge rod is rotatably connected to the inner wall of the top end of the sliding rod.

[0022] The utility model has the following beneficial effects:

[0023] 1. In the utility model, by rotating the rotating block to drive the connecting rod and the hinge rod, the wedge blocks are made to approach each other and disengage from the positioning grooves. Then, taking advantage of the fact that the length of the sliding rod extending from the fixed rod is equal to the width of the shaft body, the two shaft bodies can be quickly inserted and spliced. The quick-splicing structure also makes the application of the bearing in large equipment or complex working conditions more convenient, improving the overall installation and maintenance efficiency of the equipment.

Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0034] Refer to Figure 1 - Figure 3, An embodiment provided by the present utility model: An environment-friendly oil-free lubricating bearing, including a shaft body 1. The shaft body 1 is an oil-free lubricating bearing in the prior art, with an inner ring provided inside. Two sets of cavities are provided on the surface of the shaft body 1. A splicing component 2 is provided on the inner wall of the cavity of the shaft body 1, and a quick-release component 3 is provided on the surface of the shaft body 1. The splicing component 2 includes a fixing rod 21. Two sets of through holes are provided on the surface of the shaft body 1. The outer wall of the fixing rod 21 is in contact with the inner wall of the through hole. The contact between the two can position and splice the two shaft bodies 1, so as to cope with some special installation positions where two shaft bodies 1 need to be installed simultaneously.

[0035] Refer to Figure 2 - Figure 4 , The outer wall of the wedge block 26 is in contact with the surface of the shaft body 1. The contact between the two can, after splicing the two shaft bodies 1, contact the surface of another shaft body 1 passing through through the plane at the bottom end of the wedge block 26, so as to quickly splice and fix the two shaft bodies 1. The fixing rod 21 is rotatably connected to the inner wall of the cavity on the surface of the shaft body 1. Positioning grooves are provided on both sides of the inner wall of the cavity of the shaft body 1. The wedge block 26 is clamped with the inner wall of the positioning groove. The clamping between the two can store the whole splicing component 2 inside the shaft body 1 when not in use. A sliding rod 22 is slidably connected to the inner wall of the fixing rod 21. A guide groove that fits the sliding rod 22 is provided inside the fixing rod 21, so that the whole sliding rod 22 can extend and unfold from the inside of the fixing rod 21, and the length of the sliding rod 22 that completely extends from the inner wall of the fixing rod 21 is equal to the width of the shaft body 1, so as to penetrate and splice the two shaft bodies 1. The top end of the outer wall of the sliding rod 22 is rotatably connected to a rotating block 23, and a hinge rod 25 is fixedly connected to the rotation center axis of the rotating block 23.

[0036] Refer to Figure 3 and Figure 4 , Two hinge rods 25 are hinged to the bottom end of the hinge rod 25. Wedge blocks 26 are hinged to the ends of the two hinge rods 25 away from the connecting rod 24. By rotating the rotating block 23, the connecting rod 24 can be rotated synchronously, so as to synchronously drive the two hinge rods 25 to rotate following the connecting rod 24, so that the two wedge blocks 26 approach each other, so as to disengage from the positioning groove of the shaft body 1, so that the whole can be rotated and opened inside the shaft body 1. The wedge block 26 penetrates and is slidably connected to the inner wall of the top end of the sliding rod 22. The hinge rod 25 is rotatably connected to the inner wall of the top end of the sliding rod 22. The two wedge blocks 26 are elastically connected by a limiting spring 27. By providing the limiting spring 27 between the two wedge blocks 26, the positions of the two wedge blocks 26 after approaching each other following the movement of the hinge rod 25 are automatically reset.

[0037] Refer to Figure 5 - Figure 6The quick-release assembly 3 includes a sealing sheet 31. The inner side wall of the sealing sheet 31 contacts the surface of the shaft body 1. The contact between the two can seal the surface of the shaft body 1 through the sealing sheet 31, thereby preventing dust from entering the inner ring from the surface of the shaft body 1, thereby accelerating the wear of the shaft body 1. The slider 33 can only move up and down on the inner wall of the sealing sheet 31 and cannot be separated from its inner wall. The inner wall of the sealing sheet 31 is slidably connected with two sets of upper and lower sliders 33. Both sides of the slider 33 are penetrated and slidably connected with a block 34, and the block 34 penetrates and is slidably connected to the inner wall of the slider 33.

[0038] Reference Figure 6 The inner wall of the empty groove of the sealing sheet 31 is provided with two sets of through holes, the card block 34 is plugged into the inner wall of the through hole, and the plugging between the two, when the card block 34 is plugged into the outer through hole, the slider 33 drives the positioning block 32 to be fixed at the position where the inner wall of the shaft body 1 and the inner wall of the positioning groove of the shaft body 1 are plugged, and when plugged into the inner through hole, the positioning block 32 is separated from the inner wall of the positioning groove, so as to facilitate the removal of the sealing sheet 31 and to inspect its interior. The two sets of card blocks 34 are elastically connected by the reset spring 35 Then, a reset spring 35 is provided between the two groups of blocks 34 so that the two groups of blocks 34 are moved closer to each other to automatically reset the position of the through hole of the sealing sheet 31. The outer wall of the slider 33 is fixedly connected with a positioning block 32. The inner side wall of the shaft body 1 is provided with two groups of positioning grooves, the positioning block 32 is clamped with the inner wall of the positioning groove, and the clamping connection between the two can fix the sealing sheet 31 on the surface of the shaft body 1 to prevent dust from entering the interior from the surface of the shaft body 1, thereby increasing the wear of the inner ring.

[0039] Working principle: When it is necessary to splice two groups of shaft bodies 1, the connecting rod 24 can be rotated synchronously by rotating the rotating block 23, and the two groups of hinged rods 25 can be driven to rotate along with the connecting rod 24, so that the two groups of wedge blocks 26 are close to each other and disengaged from the positioning groove of the shaft body 1, and the whole can be rotated apart inside the shaft body 1, and the sliding rod 22 can be extended and unfolded from the inside of the fixed rod 21 as a whole, and the length of the sliding rod 22 completely extended from the inner wall of the fixed rod 21 is equal to the width of the shaft body 1, so that the two groups of shaft bodies 1 can be inserted and spliced, and the plane at the bottom end of the wedge block 26 contacts the surface of the other group of shaft bodies 1 that have passed through, so that the two groups of shaft bodies 1 can be quickly spliced ​​and fixed.

[0040] When it is necessary to detect the inner ring, hold the two sets of clamping blocks 34 to make them approach each other, so as to disengage from the through hole at the current position of the sealing piece 31, and then move the clamping block 34 downward to drive the slider 33 to move synchronously, so that the positioning block 32 disengages from the clamping of the inner positioning groove of the shaft body 1, and then quickly disassemble and remove the sealing piece 31, without having to use a special tool to pry open the sealing piece 31, which may cause wear of the sealing piece 31, and dust will penetrate into the inner ring from the gap, thus accelerating the wear of the shaft body 1.

[0041] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or perform equivalent replacements for some of the technical features. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
