Description

Technical Field

[0001] This utility model relates to the field of engine technology, and in particular to an emergency lubrication connecting rod bushing. Background Technology

[0002] Whether it's a car engine, a marine engine, or an industrial engine, all rely on emergency lubrication connecting rod bushings to function in critical moments. During engine operation, the connecting rod, as a crucial component connecting the piston and crankshaft, withstands immense pressure and impact forces. When the engine's main lubrication system malfunctions, such as an oil pump failure, oil line blockage, or oil leakage, the emergency lubrication connecting rod bushing can promptly release stored lubricating oil, providing lubrication to the connecting rod's mating parts with the crankshaft, piston pins, and other components. This prevents these critical components from wearing or burning due to lack of lubrication, thus avoiding serious engine damage and ensuring the engine can continue operating for a period of time so that operators can identify the problem and take appropriate action.

[0003] However, the existing emergency lubrication connecting rod bushings have a relatively simple lubrication method, which usually relies on the lubricating oil stored in the bushing itself for passive lubrication. Therefore, it is easy to cause wear on the connecting rod. In addition, the existing emergency lubrication connecting rod bushings store lubricating oil by relying on the lubricating oil droplets splashed up when the engine is running, so that the excess lubricating oil enters the oil reservoir of the bushing. This method takes a long time to replenish the lubricating oil and the capacity of the lubricating oil that can be stored is small. Once the stored lubricating oil is exhausted, if the normal lubrication system has not been restored, the connecting rod will still face the problem of insufficient lubrication, which may lead to wear or even damage to the components.

[0004] Therefore, we propose an emergency lubrication connecting rod bushing to solve the above problems. Utility Model Content

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] An emergency lubrication connecting rod bushing includes a bushing body for emergency lubrication of the connecting rod bushing, an inner liner ring is fixedly installed on the inner side of the bushing body, and an oil reservoir is formed on the inner side of the bushing body, the oil reservoir being distributed in a ring around the inner wall of the bushing.

[0007] Specifically, sealing gaskets are fixedly installed on both the upper and lower sides of the bushing body to enhance sealing and reduce the outflow of lubricating oil.

[0008] Specifically, lip-shaped sealing rings are fixedly installed on the inner side of both sealing gaskets, which increases the sealing performance at the connection with the connecting rod.

[0009] Specifically, an oil storage shell is fixedly fitted on the outer side of the bushing body, and an oil storage chamber is formed inside the oil storage shell.

[0010] Specifically, the top of the oil storage shell is provided with a receiving groove, and an oil pipe is fixedly installed on the bottom inner wall of the receiving groove. The oil pipe is fixedly installed at the bottom of the receiving groove and communicates with the oil storage chamber to facilitate the replenishment of oil in the oil storage chamber.

[0011] Specifically, multiple replenishment pipes are fixedly installed on the inner side of the oil storage shell. One end of each replenishment pipe extends into the oil storage chamber, and the other end of each replenishment pipe extends into the oil storage tank, so as to facilitate the replenishment of lubricating oil in the oil storage tank.

[0012] Specifically, the inner side of the inner liner ring is provided with multiple lubrication holes to facilitate the entry or seepage of lubricating oil.

[0013] Specifically, the surface of the inner liner ring is coated with molybdenum disulfide, which gives the surface of the inner liner ring good layered sliding characteristics and can form a firm and smooth lubricating film on the contact surface between the inner liner ring and the connecting rod, effectively reducing friction.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: by setting up an oil storage shell, the internal lubricating oil can be replenished to the oil storage shell regularly through the oil pipe. At the same time, when the connecting rod is working, the excess lubricating oil will enter the oil storage tank through multiple lubrication holes opened on the inner liner ring, thereby increasing the oil storage capacity of the bushing and extending its lubrication time in emergency situations, providing time for staff to discover problems and take corresponding measures.

[0021] Reference Figure 1-5 An emergency lubrication connecting rod bushing includes a bushing body 1 for emergency lubrication of the connecting rod bushing. An inner liner ring 401 is fixedly installed on the inner side of the bushing body 1. An oil reservoir 102 is provided on the inner side of the bushing body 1, and the oil reservoir 102 is distributed in a ring around the inner wall of the bushing.

[0022] In this embodiment, sealing gaskets 201 are fixedly installed on both the upper and lower sides of the bushing body 1, which can enhance the sealing performance and reduce the outflow of lubricating oil.

[0023] In this embodiment, lip-shaped sealing rings 202 are fixedly installed on the inner side of both sealing gaskets 201, which increases the sealing performance at the connection with the connecting rod.

[0024] In this embodiment, an oil storage shell 301 is fixedly sleeved on the outer side of the bushing body 1, and an oil storage chamber 302 is opened inside the oil storage shell 301.

[0025] In this embodiment, the top of the oil storage shell 301 is provided with a receiving groove, and an oil pipe 303 is fixedly installed on the bottom inner wall of the receiving groove. The oil pipe 303 is fixedly installed at the bottom of the receiving groove and communicates with the oil storage chamber 302, so as to facilitate the replenishment of oil in the oil storage chamber 302.

[0026] In this embodiment, a plurality of replenishment pipes 304 are fixedly installed on the inner side of the oil storage shell 301. One end of each replenishment pipe 304 extends into the oil storage chamber 302, and the other end of each replenishment pipe 304 extends into the oil storage tank 102, so as to facilitate replenishment of lubricating oil in the oil storage tank 102.

[0027] In this embodiment, the inner side of the inner liner ring 401 is provided with a plurality of lubrication holes 402 to facilitate the entry or seepage of lubricating oil.

[0028] In this embodiment, the surface of the inner liner ring 401 is provided with a molybdenum disulfide coating, which can give the surface of the inner liner ring 401 good layered sliding characteristics, and can form a firm and smooth lubricating film on the contact surface between the inner liner ring 401 and the connecting rod, effectively reducing friction.

[0029] Working principle: During routine use and maintenance, staff can replenish lubricating oil to the oil reservoir chamber 302 within the oil reservoir shell 301 via oil pipe 303 during maintenance. This extends the emergency lubrication time and prevents insufficient lubrication of the connecting rod, which could lead to component wear or even damage. When the main oil passage pressure drops, the pressure difference between the oil reservoir chamber 302 and the oil reservoir 102 drives oil to flow through the replenishment pipe 304 to the oil reservoir 102, thus lubricating the connecting rod in emergencies. During normal operation, a lubricating oil film exists on the surface of the connecting rod, while excess lubricating oil enters the oil reservoir 102 through multiple lubrication holes 402 on the inner liner ring 401 to fill it for unforeseen needs. Simultaneously, the surface of the inner liner ring 401... The surface is coated with a molybdenum disulfide coating, which has an extremely low coefficient of friction. Under dry friction conditions, this coating has good laminar sliding characteristics and can form a firm and smooth lubricating film on the contact surface between the inner liner ring 401 and the connecting rod, effectively reducing friction. In case of emergency, the lubricating oil in the oil reservoir 102 device will seep out through multiple lubrication holes 402 to lubricate the surface of the connecting rod. Since the diameter of the lubrication holes 402 is small, it can prevent excessive leakage of lubricating oil. While the lubricating oil seeps out through the lubrication holes 402, the lubricating oil in the oil reservoir chamber 302 enters the oil reservoir 102 through the replenishment pipe 304, thereby extending the emergency lubrication time and providing more time for the staff to find the problem and take corresponding measures.

[0030] The technological advancement of this invention compared to the prior art is that the lubricating oil inside the oil storage shell 301 can be replenished periodically through the oil pipe 303. At the same time, when the connecting rod is working, the excess lubricating oil will enter the oil storage tank 102 through the multiple lubrication holes 402 opened on the inner liner ring 401, thereby increasing the overall oil storage capacity and extending its lubrication time in emergency situations, providing more time for staff to discover problems and take corresponding measures.
