Description

Technical Field

[0001] The utility model relates to the technical field of bearings, in particular to a sliding bearing that is easy to lubricate. Background Art

[0002] Sliding bearings are bearings that work under sliding friction. Sliding bearings work smoothly, reliably and quietly. Under liquid lubrication conditions, the sliding surfaces are separated by lubricating oil without direct contact, which can greatly reduce friction loss and surface wear. The oil film also has a certain vibration absorption capacity. However, the starting friction resistance is relatively large. The part of the shaft supported by the bearing is called the journal, and the part that matches the journal is called the bearing shell. The layer of anti-friction material cast on the inner surface of the bearing shell to improve the friction properties of the bearing shell surface is called the bearing liner. The materials of the bearing shell and the bearing liner are collectively referred to as sliding bearing materials. Sliding bearings are generally used under low-speed and heavy-load conditions, or in operating parts where maintenance and lubrication are difficult.

[0003] According to a Chinese patent application numbered "CN211599301U," a sliding bearing comprises a base and a bearing, wherein fixing holes are provided on the left and right sides of the upper surface of the base, a lower bearing seat is fixedly connected in the middle of the upper surface of the base, a first connecting plate is fixedly connected above the left and right ends of the lower bearing seat, a first guide rail is provided at the front and rear ends of the middle of the upper surface of the lower bearing seat, an upper bearing seat is provided at the upper end of the lower bearing seat, a second connecting plate is fixedly connected below the left and right ends of the upper bearing seat, the second connecting plate corresponds to the first connecting plate, a second guide rail is provided at the front and rear ends of the middle of the bottom of the upper bearing seat, and an oil guide hole is provided in the middle of the surface of the upper bearing seat. This sliding bearing improves the stability of the upper bearing seat during installation by using a slot and a plate, facilitates assembly of the upper bearing seat by using a fixing screw, a fixing nut, a first connecting plate, and a second connecting plate, and facilitates the addition of lubricating oil by using an oil filling hole and an oil guide hole.

[0004] However, the existing sliding bearings have the following disadvantages when in use: during operation, lubricating oil needs to be added to the inside of the bearing through the oil filling hole structure on the top of the sliding bearing, and the lubricating oil will enter between the shaft seat and the outer wall of the bearing shell for lubrication. The existing sliding bearing lubricating oil filling structure cannot ensure the uniformity of the lubricating oil coating after filling, and the lubrication efficiency is low. Therefore, an easy-to-lubricate sliding bearing is proposed to solve the above-mentioned problems. Utility Model Content

[0005] The technical problem to be solved by the present invention is to provide a sliding bearing that is easy to lubricate in view of the deficiencies in the above-mentioned prior art.

[0006] In order to solve the above technical problems, the technical solution adopted by the present invention is:

[0007] An easily lubricated sliding bearing comprises a sliding bearing body, an oil storage tank is provided inside the sliding bearing body, and a lubricating mechanism is provided at the bottom of the oil storage tank;

[0008] The lubrication mechanism includes an oil outlet, a vertical groove, a cross bar, a slide bar, an arc plate, a ball, a spring, and a limit block;

[0009] There are three oil outlets and three vertical slots, each of which is located within the sliding bearing body. The top of the oil outlet is connected to the oil storage tank, and the top of the vertical slot is connected to the bottom of the oil outlet. The bottom of the vertical slot is arc-shaped and extends to the top inner wall of the sliding bearing body. The crossbar is fixedly connected to the interior of the vertical slot. The middle portion of the sliding rod slides through the crossbar, and the bottom of the sliding rod is fixedly connected to the arc plate. The top of the ball bearing is slidably connected to the bottom of the arc plate, and the bottom of the ball bearing is slidably connected to the bottom arc-shaped inner wall of the vertical slot. The crossbar is provided to limit the upward and downward movement of the sliding rod.

[0010] Preferably, the spring is sleeved on the outside of the slide bar, the top end of the spring is fixedly connected to the cross bar, and the bottom end of the spring is fixedly connected to the arc plate. The slide bar is driven to return to its original position by the spring.

[0011] Preferably, the limit block is fixedly connected to the top end of the slide rod, and the limit block is arranged inside the oil outlet.

[0012] Preferably, a clamping mechanism is provided at the top of the oil storage tank, the clamping mechanism including a feed pipe, the feed pipe being fixedly connected to the top of the sliding bearing body, the bottom end of the feed pipe being in communication with the top of the oil storage tank, the feed pipe being externally covered with a round cover, the outer wall of the feed pipe and the inner wall of the round cover being provided with a sealing layer. The feed pipe is sealed by providing the round cover.

[0013] Preferably, an arc-shaped slide rail and a card slot are provided through the outer wall of the feed pipe, and a card block is fixedly connected to the inner wall of the round cover, and the card block is clamped in the inner part of the card slot.

[0014] Preferably, the bottom of the sliding bearing body is fixedly connected to a base, and two mounting screw holes are provided through the top of the base.

[0015] The utility model adopts the above technical solution, which can bring the following beneficial effects:

[0016] 1. When the workpiece is inserted into the sliding bearing body, the outer wall of the workpiece will contact the bottom end of the ball and push the ball upward into the vertical groove. When the workpiece slides inside the sliding bearing body, the friction force will drive the ball to rotate. As a result, the three balls will apply the lubricating oil in the vertical groove to the outer wall of the workpiece during the rotation process, thereby evenly lubricating the outer wall of the workpiece and the inner wall of the sliding bearing body.

[0017] 2. Through the mutual cooperation among the feed pipe, the round cover, the arc-shaped slide rail, the card slot, the card block and the sealing layer, the oil storage tank can be sealed after the lubricating oil is added to prevent the lubricating oil inside the oil storage tank from leaking.
