Description

Technical Field

[0001] The present application relates to the technical field of oil replenishment for sliding bearings, and in particular to an oil replenishment structure for sliding bearings. Background Art

[0002] The operation of sliding bearings depends on the lubricating film between the shaft and the sleeve. This lubricating film is formed by lubricating oil or grease, which can reduce the direct contact between the shaft and the sleeve, thereby reducing friction and wear. Regular oil replenishment can ensure the heat dissipation performance of the bearing and prevent overheating. Therefore, regular oil replenishment can ensure the existence and effectiveness of this lubricating film. Although the existing oil replenishing equipment can first set a certain amount of lubricating oil and then replenish the bearing, it is impossible to spray the lubricating oil evenly to various positions of the bearing, resulting in excessive local lubricating oil. On the one hand, it flows out and causes waste. On the other hand, the uneven oil replenishment causes greater friction of the bearing, affecting its normal rotation effect. Utility Model Content

[0003] The purpose of the present application is to provide an oil replenishing structure for sliding bearings, which solves the problem that although the existing oil replenishing equipment proposed in the background technology can first set a certain amount of lubricating oil and then replenish the bearing with oil, it is impossible to evenly spray the lubricating oil to various positions of the bearing, thereby causing excessive local lubricating oil. On the one hand, it flows out and causes waste, and on the other hand, the uneven oil replenishment causes greater friction of the bearing, affecting its normal rotation effect.

[0004] To achieve the above-mentioned purpose, the present application provides the following technical scheme: an oil replenishing structure for a sliding bearing, comprising a base, a fixed block, a collecting plate and an oil replenishing tank, a bottom groove is provided on the right side of the top of the base, a No. 1 threaded rod is rotatably connected to the inner side of the bottom groove, a No. 1 threaded block is threadedly connected to the surface of the No. 1 threaded rod, a collecting plate is fixedly connected to the top of the No. 1 threaded block, a supporting shaft is rotatably connected to the center of the top of the collecting plate, a placing plate is fixedly connected to the top of the supporting shaft, an adjusting groove is provided on the top of the placing plate, a bidirectional screw rod is rotatably connected to the inner side of the adjusting groove, clamping blocks are threadedly connected to the two sides of the surface of the bidirectional screw rod, a fixed block is fixedly connected to the left side of the top of the base, and a top groove is vertically provided on the right side wall of the fixed block. A No. 2 threaded rod is vertically rotatably connected to the inner side of the top groove, and a No. 2 threaded block is threadedly connected to the surface of the No. 2 threaded rod, and a support frame is fixedly welded to the right side wall of the No. 2 threaded block, and an oil storage tank is fixedly installed on the left side of the top of the support frame, and an electric push rod is fixedly installed on the top of the support frame on the right side of the oil storage tank, and the bottom telescopic end of the electric push rod passes through the top of the support frame and is fixedly connected to the top of the extrusion rod, and the bottom of the extrusion rod is connected to the extrusion plate, and the extrusion plate is located on the inner side of the oil replenishing tank and is vertically slidably connected to the inner side of the oil replenishing tank, the oil replenishing tank is fixedly installed on the surface of the protruding bracket below the support frame, an oil inlet pipe is connected between the oil replenishing tank and the oil storage tank, and an air pressure port is provided on the right side wall of the oil replenishing tank, and an oil outlet pipe is provided at the bottom of the oil replenishing tank.

[0005] In this technical solution, the bearing is placed on the surface of the placement plate, and then the rotating block is manually rotated to drive the clamping blocks closer to each other, thereby clamping the bearing to keep it stable during the oil replenishment process. Since the clamping block is movable, it can adapt to the limit of bearings of various sizes. After the bearing is fixed, the No. 1 motor is started to drive the No. 1 threaded rod to rotate, so that the No. 1 threaded block brings the upper collecting plate and the placement plate to the bottom of the oil outlet pipe, and adjusts according to the size of the bearing and the position where oil replenishment is required. When replenishing oil, the rotating motor is started to drive the upper placement plate to rotate, so that during the oil replenishment process, the various oil replenishment parts of the bearing can be evenly replenished with oil, thereby improving the efficiency of oil replenishment. When replenishing oil, the No. 2 motor is started to drive the No. 2 threaded rod to rotate. The threaded rod rotates to make the No. 2 threaded block descend with the support frame, so that the oil outlet pipe is close to the bearing and is adjusted according to the size and width of the bearing to prevent the lubricating oil from being sprayed everywhere due to the height being too high. When the lubricating oil needs to be filled, open the oil inlet valve and the lubricating oil in the oil storage tank will flow into the oil filling tank along the oil inlet pipe. During the refueling process, the air pressure port needs to be opened to maintain the air pressure in the tank stable. After the oil filling is completed, the air pressure port is blocked again. At this time, the electric push rod is energized and started, extending downward, pushing the extrusion rod downward to push the lubricating oil, so that the lubricating oil is sprayed out from the oil outlet pipe. Since the electric push rod extends at a uniform speed, it replaces manual extrusion, which can ensure uniform oil output, and cooperates with the rotating placement plate to achieve the effect of uniform oil replenishment to the bearing, thereby improving the practicality of the device.

[0006] As an optional solution of the technical solution of the present application, the bottom end of the oil inlet pipe and the air pressure port are located on the side wall of the oil replenishing tank below the extrusion plate, and an oil inlet valve is installed at the connection between the oil inlet pipe and the oil replenishing tank, and an oil outlet valve is installed at the connection between the oil outlet pipe and the oil replenishing tank.

[0007] As an optional solution of the technical solution of the present application, one end of the bidirectional screw rod passes through the adjustment slot and is located on the outside of the placement plate, and the end of the bidirectional screw rod that passes through is fixedly connected to the rotating block.

[0008] As an optional solution to the technical solution of the present application, a No. 1 motor is fixedly installed on the right side wall of the base facing the right end of the No. 1 threaded rod, and the outer end of the transmission shaft of the No. 1 motor is fixedly connected to the right end of the No. 1 threaded rod, and a No. 2 motor is fixedly installed on the top of the fixed block facing the top end of the No. 2 threaded rod, and the tail end of the transmission shaft of the No. 2 motor is fixedly connected to the top of the No. 2 threaded rod.

[0009] As an optional solution of the technical solution of the present application, a rotating motor is fixedly installed in the center of the inner part of the collecting plate, and the outer end of the transmission shaft of the rotating motor is fixedly connected to the supporting shaft above.

[0010] As an optional solution of the technical solution of the present application, a discharge outlet is provided through the center of the left protruding side wall of the collecting plate.

[0011] Compared with the prior art, the beneficial effects of this application are as follows:

[0012] 1. The present application starts with motor No. 1, which drives threaded rod No. 1 to rotate, so that threaded block No. 1 brings the collecting plate and placement plate above to the bottom of the oil outlet pipe. When replenishing oil, the rotating motor and the rotating motor are started to respectively drive the placement plate and threaded rod No. 2 to rotate, and threaded block No. 2 brings the support frame down, so that the oil outlet pipe is close to the bearing to prevent the lubricating oil from being sprayed everywhere due to excessive height. Therefore, in the process of replenishing oil, various oil replenishing parts of the bearing can be evenly replenished with oil, and the electric push rod is powered on and started, extending downward, pushing the extrusion rod to push the lubricating oil downward at a uniform speed, replacing manual extrusion, which can ensure uniform oil output, thereby achieving the effect of evenly replenishing oil to the bearing and improving the efficiency of oil replenishment.

[0013] 2. The present application places the bearing on the surface of the placement plate, and then manually rotates the rotating block to drive the clamping blocks closer to each other, thereby clamping the bearing to keep it stable during the oil replenishment process. Since the clamping blocks are movable, they can adapt to bearing limits of various sizes, thereby improving the adaptability of the device. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0019] In order to make the technical means, creative features, objectives and effects of the utility model easier to understand, they are further explained below in conjunction with specific implementation methods.

[0024] like Figure 2 As shown, a motor No. 101 is fixedly installed on the right side wall of the base 1 facing the right end of the No. 1 threaded rod 3, and the outer end of the transmission shaft of the motor No. 101 is fixedly connected to the right end of the No. 1 threaded rod 3. A motor No. 201 is fixedly installed on the top of the fixed block 12 facing the top of the No. 2 threaded rod 14, and the tail end of the transmission shaft of the motor No. 201 is fixedly connected to the top of the No. 2 threaded rod 14. A rotating motor 601 is fixedly installed at the inner center of the collecting plate 5, and the outer end of the transmission shaft of the rotating motor 601 is fixedly connected to the upper support shaft 6.

[0025] like Figure 2As shown, a discharge port 501 is provided through the center of the left protruding side wall of the collecting plate 5 , and the discharge port 501 can discharge the lubricating liquid leaked on the collecting plate 5 during the oil replenishing process.

[0026] like Figure 3 As shown, the bottom telescopic end of the electric push rod 18 passes through the top of the support frame 16 and is fixedly connected to the top of the extrusion rod 19. The bottom of the extrusion rod 19 is connected to the extrusion plate 191, and the extrusion plate 191 is located on the inner side of the oil replenishing tank 20 and is vertically slidably connected to the inner side of the oil replenishing tank 20.

When replenishing oil, the No. 2 motor 141 is started to drive the No. 2 threaded rod 14 Rotate to make the No. 2 threaded block 15 descend with the support frame 16, so that the oil outlet pipe 23 is close to the bearing, and is adjusted according to the size and width of the bearing to prevent the lubricating oil from being sprayed everywhere due to excessive height. When the lubricating oil needs to be refilled, open the oil inlet valve 211, and the lubricating oil in the oil storage tank 17 will flow into the oil replenishing tank 20 along the oil inlet pipe 21. During the refueling process, the air pressure port 22 needs to be opened to maintain the air pressure in the tank stable.
