Description

Technical Field

[0001] The present invention relates to the technical field of bearings, and in particular to a bearing with a wear warning function. Background Art

[0002] Bearing is an important component in mechanical equipment. It plays a key role in the operation of the machine. It is mainly used to support the mechanical rotating body and reduce the friction coefficient during its movement, so as to ensure the rotation accuracy of the machine. The steel balls of the bearing will wear due to lack of lubricating oil during operation. However, in the prior art, when the bearing is worn, it is necessary to detect it through the sound of the bearing operation or temperature detection equipment to determine whether the bearing has a wear problem. At this time, the bearing has caused serious wear due to long-term operation due to lack of lubricating oil. Therefore, the bearing needs to be replaced, which increases the cost of operating the mechanical equipment and causes unnecessary waste. For this reason, the present invention improves the timely addition of lubricant when wear is just about to occur to reduce further wear of the bearing. Summary of the invention

[0003] The disclosed embodiment relates to a bearing with a wear warning. When wear just occurs, the temperature of the inner side of the outer ring and the outer side of the inner ring rises first. The temperature rise causes the thermal plate in the detection cavity to expand and move, so that the thermal plate pushes the traction plate to drive the block to remove the obstruction of the guide 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, thereby reducing the problem of further aggravated wear of the ball, promptly solving the problem of further aggravated wear of the bearing, preventing the staff from being unable to timely discover the bearing wear and lubricating and protecting the bearing, ensuring the normal operation of the bearing, and reducing the cost of replacing bearings in mechanical equipment.

[0004] According to a first aspect of the present disclosure, a bearing with a wear warning function is provided, which specifically comprises: an outer ring and an inner ring, wherein the outer ring is an annular structure, and a groove is provided on the inner side of the outer ring, and the inner ring is provided on the inner side of the outer ring; a groove is provided on the outer side of the inner ring, and balls are installed between the outer side of the inner ring and the inner side of the outer ring; a slide groove is provided on the top of the outer ring; the slide groove is an annular structure, and a guide groove is provided on the side of the slide groove; a positioning groove is provided on the bottom of the outer ring and the inner ring; the inner side of the positioning groove is an arc-shaped structure.

[0005] Furthermore, a lubricating oil storage chamber is provided inside the outer ring and the inner ring; the lubricating oil storage chamber is an annular structure, and an oil filling hole is provided on the side of the lubricating oil storage chamber facing the outer side, and a sealing member is provided in the oil filling hole; a detection chamber is provided in the middle position inside the outer ring and the inner ring.

[0006] Furthermore, a wireless temperature sensor is installed inside the detection cavity; a guide groove is provided on one side of the lubricating oil storage cavity; and the outer end of the guide groove is connected to the grooves on the inner side of the outer ring and the outer side of the inner ring.

[0007] Furthermore, two upper and lower movable plates are installed inside the detection cavity; the movable plate is a ring structure, and a heat-sensitive 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 interior of 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 on the side end of the traction plate; and the stopper is slidably installed on the inner end of the guide groove.

[0010] Furthermore, a guide plate is slidably installed inside the guide groove and the slide groove; 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 plate structure.

[0011] Furthermore, a shift block is installed on the outer side of the guide plate; the shift block is a cylindrical structure, and a fixing rod is rotatably installed in the middle position of the top of the shift block.

[0012] Furthermore, an antenna bracket is rotatably installed inside the slide groove; the antenna bracket is an arc-shaped plate structure, and the bottoms 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.

[0014] The present invention provides a bearing with a wear warning function, which has the following beneficial effects: When the present invention is in use, lubricating oil is injected into the bearing through the guide groove to reduce further aggravated wear of the bearing. When the bearing is worn during operation, the temperature of the inner side of the outer ring and the outer side of the inner ring first rises when the wear just occurs. The temperature rise causes the thermal plate in the detection cavity to expand and move, so that the thermal plate pushes the traction plate to drive the block to remove the obstruction of the guide 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, thereby reducing the problem of further aggravated wear of the ball, and promptly solving the problem of further aggravated wear of the bearing, preventing the staff from being unable to timely discover the bearing wear and lubricate the bearing for protection, thereby ensuring the normal operation of the bearing and reducing the cost of replacing the bearing of mechanical equipment.

[0015] In addition, the dye flowing out of the ruptured dye airbag is used to remind the staff to check the bearing wear. When the bearing wears during operation, 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. The thermal plate pushes the traction plate to drive the piercing rod to pierce the dye airbag, so that the dye in the dye airbag flows out. The on-site staff can be reminded, the cause of the bearing wear can be judged in time, and reasonable solutions can be taken to prevent further wear of the bearing from affecting the normal operation of the mechanical equipment.
