Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of bearings, and in particular to a bearing with wear warning. Background Art
[0002] A bearing is an important component in mechanical equipment. It plays a key role in mechanical operation, mainly used to support the rotating body of the machine, reduce the friction coefficient during its movement, and thus ensure the rotational accuracy of the machine. During the operation of the bearing, the steel balls will wear due to lack of lubricating oil. However, in the prior art, when the bearing wears, it is necessary to detect whether the bearing has a wear problem through the sound of the bearing operation or a temperature detection device. At this time, the bearing has suffered significant wear due to long-term operation without lubricating oil. Therefore, it is necessary to replace the bearing, which increases the operation cost of the mechanical equipment and causes unnecessary waste. For this reason, the present invention improves the addition of lubricant in a timely manner when wear is about to occur to reduce further wear of the bearing. Summary of the Invention
[0003] An embodiment of the present disclosure relates to a bearing with wear warning. When wear first occurs, the temperature of the inner side of the outer ring and the outer side of the inner ring rises first. Then, the thermal expansion of the thermal sensitive plate in the detection cavity is caused by the temperature rise, which moves the thermal sensitive plate to push the traction plate to drive the stopper to remove the blockage of the diversion groove. The lubricating oil in the lubricating oil storage cavity flows to the grooves on the inner side of the outer ring and the outer side of the inner ring in a timely manner for lubrication, reducing the problem of further wear of the rolling balls, timely solving the problem of further wear of the bearing, preventing the staff from being unable to detect the wear of the bearing in time for lubrication protection, ensuring the normal operation of the bearing, and reducing the cost of replacing the bearing of the mechanical equipment.
[0004] In the first aspect of the present disclosure, a bearing with wear warning is provided, which specifically includes: an outer ring and an inner ring. The outer ring is of a ring structure, and a groove is provided on the inner side of the outer ring, and the inner ring is arranged at the inner side position of the outer ring; a groove is provided on the outer side of the inner ring, and rolling balls are installed between the outer side of the inner ring and the inner side of the outer ring; a chute is opened at the top of the outer ring; the chute is of a ring structure, and a guiding groove is opened on the side surface of the chute; positioning grooves are provided at the bottoms of the outer ring and the inner ring; the inner side of the positioning groove is of an arc structure.
[0005] Further, a lubricating oil storage cavity is provided inside the outer ring and the inner ring; the lubricating oil storage cavity is of a ring structure, and an oil injection hole is opened on one side of the lubricating oil storage cavity facing the outer side, and a sealing member is provided in the oil injection hole; a detection cavity is opened at the middle position inside the outer ring and the inner ring.
[0006] Furthermore, a wireless temperature sensor is installed inside the detection chamber; a diversion groove is provided on one side of the lubricating oil storage chamber; the outer end of the diversion groove communicates with the grooves on the inner side of the outer ring and the outer side of the inner ring.
[0007] Furthermore, two movable plates are installed inside the detection chamber; the movable plates are annular structures, and a thermosensitive plate is installed between the two movable plates.
[0008] Furthermore, a connecting rod is installed on the outer side of the movable plate; the side end of the connecting rod is inserted into the lubricating oil storage chamber and connected to the traction plate.
[0009] Furthermore, a spring is installed on the outer side of the traction plate, and the outer side of the traction plate is installed inside the lubricating oil storage chamber through the spring; a stopper is installed at the side end of the traction plate; the stopper is slidably installed at the inner end of the diversion groove.
[0010] Furthermore, a guide plate is slidably installed inside the guide groove and the chute; the guide plate is an annular structure, and a guide push block is installed on the outer side of the guide plate, wherein the guide push block is an arc-shaped plate structure.
[0011] Furthermore, a dial block is also installed on the outer side of the guide plate; the dial block is a cylindrical structure, and a fixed rod is rotatably installed at the middle position of the top of the dial block.
[0012] Furthermore, an antenna bracket is rotatably installed inside the chute; the antenna bracket is an arc-shaped plate structure, and the bottom ends of both ends of the antenna bracket are inclined structures, and a guide push block is slidably installed at the bottom of the antenna bracket.
[0013] Furthermore, a dye airbag is installed inside the positioning groove; the dye airbag is a spherical structure made of rubber, and the inside of the dye airbag is filled with dye; a thorn rod is installed on the outer side of the traction plate; the outer end of the thorn rod is a conical structure, and the outer end of the thorn rod is inserted into the positioning groove.
[0014] The present invention provides a bearing with wear warning, having the following beneficial effects:
[0015] When the present invention is in use, lubricating oil is injected into the bearing through the diversion groove to reduce further wear of the bearing. When wear occurs during the operation of the bearing, at the beginning of wear, the temperature of the inner side of the outer ring and the outer side of the inner ring rises first. Then, the temperature rise causes the thermal-sensitive plate in the detection cavity to expand and move thermally, so that the thermal-sensitive plate pushes the traction plate to drive the stopper to cancel the blockage of the diversion groove. The lubricating oil in the lubricating oil storage cavity flows to the grooves on the inner side of the outer ring and the outer side of the inner ring in time for lubrication, reducing the problem of further wear of the rolling elements, timely solving the problem of further wear of the bearing, preventing the staff from failing to timely detect the wear of the bearing and lubricating and protecting the bearing, ensuring the normal operation of the bearing, and reducing the cost of replacing the bearing of the mechanical equipment.
[0016] In addition, the dye flowing out of the ruptured dye airbag is used to remind the staff to check the wear condition of the bearing. When wear occurs during the operation of the bearing, the wireless temperature sensor in the detection cavity detects the temperature rise caused by the wear and transmits the detection situation to the detection center of the equipment. Moreover, the thermal-sensitive plate pushes the traction plate to drive the thorn rod to pierce the dye airbag, so that the dye in the dye airbag flows out, which can remind the on-site staff, timely judge the cause of the wear of the bearing, and take reasonable solutions to prevent the further wear of the bearing from affecting the normal operation of the mechanical equipment.

[0032] To make the objectives, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are some but not all of the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the described embodiments of the present invention without creative efforts shall fall within the scope of protection of the present invention.
[0033] Please refer to Figures 1 to 8 : Embodiment 1:
[0034] The present invention provides a bearing with wear warning, comprising: an outer ring 1 and an inner ring 101. The outer ring 1 is of a ring structure, and a groove is provided on the inner side of the outer ring 1, and the inner ring 101 is arranged at the inner side position of the outer ring 1; a groove is provided on the outer side of the inner ring 101, and balls 102 are installed between the outer side of the inner ring 101 and the inner side of the outer ring 1; a lubricating oil storage cavity 103 is provided inside the outer ring 1 and the inner ring 101; the lubricating oil storage cavity 103 is of a ring structure, and an oil injection hole is provided on one side of the lubricating oil storage cavity 103 facing the outer side, and a plugging member is arranged in the oil injection hole; a detection cavity 104 is provided at the middle position inside the outer ring 1 and the inner ring 101; a wireless temperature sensor 106 is installed inside the detection cavity 104; a diversion groove 105 is provided on one side of the lubricating oil storage cavity 103; the outer end of the diversion groove 105 is communicated with the grooves on the inner side of the outer ring 1 and the outer side of the inner ring 101; two movable plates 107 are installed inside the detection cavity 104; the movable plates 107 are of a ring structure, and a thermal-sensitive plate 108 is installed between the two movable plates 107; a connecting rod 109 is installed on the outer side of the movable plate 107; the side end of the connecting rod 109 is inserted into the lubricating oil storage cavity 103 and connected to a traction plate 1010; a spring is installed on the outer side of the traction plate 1010, and the outer side of the traction plate 1010 is installed inside the lubricating oil storage cavity 103 through the spring; a stop block 1011 is installed at the side end of the traction plate 1010; the stop block 1011 is slidably installed at the inner end of the diversion groove 105.
[0035] In the embodiment of the present disclosure, when the bearing wears during operation, lubricating oil is injected into the lubricating oil storage cavity 103 through the oil injection hole on the outer side for storage. When the inner side of the outer ring 1, the outer side of the inner ring 101 and the balls 102 are worn during rotation, the temperature in the grooves on the inner side of the outer ring 1 and the outer side of the inner ring 101 rises, and the temperature is conducted to the inside of the detection cavity 104. The wireless temperature sensor 106 in the detection cavity 104 detects the higher temperature and transmits it to the mechanical equipment detection center. And the higher temperature will cause the thermal-sensitive plate 108 to expand and move thermally, then the thermal-sensitive plate 108 moves inside the detection cavity 104 to push the movable plate 107 to move. The movable plate 107 drives the connecting rod 109 to move inside the lubricating oil storage cavity 103, so that the side end of the connecting rod 109 drives the traction plate 1010 to move. The traction plate 1010 drives the stop block 1011 to lose the block on the diversion groove 105, and the lubricating oil in the lubricating oil storage cavity 103 flows into the grooves on the inner side of the outer ring 1 and the outer side of the inner ring 101 through the diversion groove 105 to lubricate the movement of the balls 102, reducing the problem of increased wear of the balls 102 due to lack of lubricant and ensuring the normal operation of the bearing.
[0036] Embodiment 2. On the basis of Embodiment 1, a chute 2 is provided at the top of the outer ring 1; the chute 2 is of an annular structure, and a guiding groove 201 is provided on the side surface of the chute 2; a guiding plate 202 is slidably installed inside the guiding groove 201 and the chute 2; the guiding plate 202 is of an annular structure, and a guiding push block 203 is installed on the outer side of the guiding plate 202, wherein the guiding push block 203 is of an arc-shaped plate structure; a dial block 204 is also installed on the outer side of the guiding plate 202; the dial block 204 is of a cylindrical structure, and a fixing rod 205 is rotatably installed at the middle position of the top of the dial block 204; an antenna support 206 is rotatably installed inside the chute 2; the antenna support 206 is of an arc-shaped plate structure, and the bottom ends of both ends of the antenna support 206 are of an inclined structure, and a guiding push block 203 is slidably installed at the bottom of the antenna support 206. During the operation of the bearing, when the outer ring 1 is fixedly installed on the mechanical equipment, the dial block 204 on the outer side of the guiding plate 202 is pushed inside the chute 2, the dial block 204 drives the guiding plate 202 to move along the guiding groove 201, the guiding plate 202 drives the guiding push block 203 to move, and the arc-shaped structure of the guiding push block 203 pushes the antenna support 206 to rotate inside the chute 2. Rotate the fixing rod 205 to fix the position of the guiding plate 202. After the antenna support 206 rotates, it is in an unfolded state, which is convenient for transmitting the signal detected by the wireless temperature sensor 106 and prevents the problem of inaccurate signal transmission.
[0037] Embodiment 3. On the basis of Embodiment 1, positioning grooves 3 are provided at the bottoms of the outer ring 1 and the inner ring 101; the inner side of the positioning groove 3 is of an arc-shaped structure; a dye airbag 301 is installed inside the positioning groove 3; the dye airbag 301 is of a spherical structure made of rubber material, and the inside of the dye airbag 301 is filled with dye; a thorn rod 302 is installed on the outer side surface of the traction plate 1010; the outer end of the thorn rod 302 is of a conical structure, and the outer end of the thorn rod 302 is inserted inside the positioning groove 3. When the bearing wears during operation, as the temperature rises, the traction plate 1010 drives the thorn rod 302 to move outward, and the outer end of the thorn rod 302 is inserted inside the positioning groove 3 to pierce the dye airbag 301, so that the dye inside the dye airbag 301 flows out through the positioning groove 3, reminding the staff of the bearing. The dye is bright in color and the display is relatively intuitive, enabling the on-site staff to promptly check the worn bearing, judge the problem of wear and take reasonable measures to prevent further wear of the wear.
[0038] Working principle of this embodiment: During use, the outer ring 1 is fixedly installed on the mechanical equipment. The slider 204 is pushed in the chute 2 to drive the guide plate 202 to move along the guide groove 201. The guide plate 202 drives the guide push block 203 to push the antenna bracket 206 to rotate in the chute 2 to the unfolded state for signal transmission detected by the wireless temperature sensor 106. When wear occurs in the rotation of the inner side of the outer ring 1, the outer side of the inner ring 101, and the ball 102, the temperature in the grooves on the inner side of the outer ring 1 and the outer side of the inner ring 101 rises. The temperature is conducted into the detection cavity 104 and detected by the wireless temperature sensor 106 for the higher temperature and then transmitted to the detection center of the mechanical equipment. The higher temperature will cause the thermal expansion of the thermosensitive plate 108 to push the movable plate 107 to move. The movable plate 107 drives the traction plate 1010 to move through the connecting rod 109. The traction plate 1010 drives the stopper 1011 to lose the blockage of the diversion groove 105. The lubricating oil in the lubricating oil storage cavity 103 flows through the diversion groove 105 into the grooves on the inner side of the outer ring 1 and the outer side of the inner ring 101 to lubricate the movement of the ball 102. At the same time, the traction plate 1010 drives the thorn rod 302 to move outward. The outer end of the thorn rod 302 is inserted into the positioning groove 3 to pierce the dye airbag 301. The dye in the dye airbag 301 flows out through the positioning groove 3 to remind the staff of the bearing. The dye is bright in color and the display is relatively intuitive, so that the on-site staff can check the worn bearing in time.
