Description

Technical Field

[0001] This utility model relates to the field of crankshaft thrust washers, and in particular to an engine crankshaft thrust washer with a fault-prevention structure. Background Technology

[0002] During engine operation, crankshaft thrust washers play a crucial role in limiting axial displacement and ensuring normal crankshaft operation. Traditional engine crankshaft thrust washers have several shortcomings in their structural design and use. First, in terms of installation, the connection structure between the inner ring and the thrust washer body is complex. Installation and disassembly often require specialized tools, making the process cumbersome and time-consuming. This increases the difficulty and cost of production assembly, severely impacting production efficiency. Furthermore, subsequent maintenance and replacement also present difficulties, leading to long repair times and high labor costs. Second, regarding installation accuracy, traditional thrust washers lack effective positioning measures, relying excessively on manual experience and operational precision. This makes them prone to displacement or misalignment due to installation errors, thus affecting the overall engine performance and reliability. Thirdly, in terms of connection stability and reliability, the traditional connection method between the thrust washer and components such as the inner ring and crankshaft is difficult to withstand the severe vibration and complex mechanical environment generated during engine operation. Displacement and loosening of components are prone to occur, increasing the probability of failure. This may not only cause mutual interference and accelerated wear of internal engine parts, shortening the engine's service life, but also pose certain safety hazards. Therefore, we propose an engine crankshaft thrust washer with a fault-proof structure to solve this problem. Utility Model Content

[0003] The purpose of this invention is to provide an engine crankshaft thrust washer with an anti-fault structure to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] An engine crankshaft thrust washer with an anti-fault structure includes: a thrust washer body, an inner ring on the inner side of the thrust washer, mounting blocks fixedly installed on both sides of the inner ring, two sets of mounting blocks movably inserted into the interior of both sides of the thrust washer body, a placement groove and a sliding groove are formed inside both sides of the thrust washer body, and an installation assembly is provided inside the placement groove and sliding groove on the same side, the installation assembly including: a connecting shaft, a fixing plate fixedly installed on the outer side of the connecting shaft, a first inclined block fixedly installed at one end of the connecting shaft, second inclined blocks movably abutting on both sides of the first inclined block, a connecting plate fixedly installed on the side of the two sets of second inclined blocks that are far apart from each other, and an insert block fixedly installed on the side of the two sets of connecting plates that are close to each other, the two sets of insert blocks movably inserted into the interior of both sides of the mounting block.

[0006] Preferably, multiple sets of positioning protrusions are fixedly installed on both sides of the thrust plate body, and multiple sets of elastic claws are provided on the inner side of the inner ring.

[0007] Preferably, the two sets of fixing plates are slidably installed inside the corresponding slide grooves, and a spring is sleeved on the outer side of each of the two sets of connecting shafts. The two ends of the springs are fixedly connected to the inner wall of one side of the corresponding fixing plate and slide groove, respectively.

[0008] Preferably, the same set of guide rods are slidably installed inside the two sets of connecting plates on the same side. The two ends of the two sets of guide rods are respectively fixedly connected to the inner walls of the corresponding placement grooves on both sides. Two sets of springs are sleeved on the outer side of the two sets of guide rods. The two ends of the four sets of springs are respectively fixedly connected to the inner side of the corresponding connecting plate and the placement groove.

[0009] Preferably, rectangular grooves are provided inside both sides of the thrust plate body, and the two sets of connecting shafts slide through the corresponding rectangular grooves. A pull plate is fixedly installed at one end of each set of connecting shafts.

[0010] Preferably, the two sets of fixing plates and pull plates are respectively adapted to the corresponding sliding grooves and rectangular grooves.

[0011] In this invention, an engine crankshaft thrust washer with an anti-misalignment structure is provided. An installation assembly is included. Pulling a pull plate causes the connecting shaft to slide within a rectangular groove. A fixed plate on the connecting shaft slides synchronously within the groove, compressing a spring. Simultaneously, a wedge block at the end of the connecting shaft moves. During the movement of the wedge block, it presses against two wedge blocks on either side, causing the connecting plate to slide along a guide rod. At this time, the spring is compressed, and the two sets of connecting plates move away from each other. This structure is simple and easy to operate, facilitating quick installation and disassembly of the inner ring and the thrust washer body, significantly shortening installation time and improving production assembly efficiency. It also makes subsequent replacement of the inner ring or the thrust washer body easier, saving maintenance time and labor costs.

[0012] In this invention, an engine crankshaft thrust washer with an anti-misalignment structure is provided. By incorporating elastic claws and positioning protrusions, the positioning protrusions on both sides of the thrust washer body can engage with corresponding structures within the engine during installation, providing positioning and ensuring accurate installation of the thrust washer body. Multiple sets of elastic claws on the inner side of the inner ring can engage with components such as the engine crankshaft to further secure the inner ring. When installing the thrust washer body, simply embedding the positioning protrusions into the corresponding structures quickly and accurately determines the installation position, avoiding installation offsets or misalignments caused by human error. This significantly improves installation accuracy and efficiency. The elastic claws, with their own elastic deformation capability, consistently maintain reliable clamping of components such as the crankshaft, preventing displacement or shaking of the inner ring and effectively reducing the risk of malfunctions caused by incorrect component installation or displacement.

[0019] In this embodiment, multiple sets of positioning protrusions 4 are fixedly installed on both sides of the thrust plate body 1, and multiple sets of elastic claws 3 are provided on the inner side of the inner ring 2. During installation, the positioning protrusions 4 can cooperate with the corresponding structures in the engine to play a positioning role and ensure that the thrust plate body 1 is installed in an accurate position. The multiple sets of elastic claws 3 on the inner side of the inner ring 2 can cooperate with components such as the engine crankshaft to further fix the inner ring 2. The two sets of fixing plates 603 are slidably installed inside the corresponding slide grooves 8. The outer sides of the two sets of connecting shafts 602 are each fitted with springs 609. The two ends of the two sets of springs 609 are fixedly connected to the inner wall of one side of the corresponding fixing plate 603 and slide groove 8, respectively, which facilitates the quick reset of the inclined block 604 and the quick installation and fixation of the inner ring 2.

[0020] In this embodiment, the same set of guide rods 608 are slidably installed inside the two sets of connecting plates 606 on the same side. The two ends of the two sets of guide rods 608 are fixedly connected to the inner walls of the corresponding placement grooves 7 on both sides. Two sets of springs 610 are sleeved on the outer side of the two sets of guide rods 608. The two ends of the four sets of springs 610 are fixedly connected to the inner side of the corresponding connecting plate 606 and placement groove 7, which facilitates the quick reset of the inclined block 605 and the quick installation and disassembly of the inner ring 2. Rectangular grooves are opened inside both sides of the thrust plate body 1. The two sets of connecting shafts 602 slide through the interior of the corresponding rectangular grooves. A pull plate 601 is fixedly installed at one end of the two sets of connecting shafts 602, which facilitates the quick movement of the connecting shafts 602. The two sets of fixed plates 603 and pull plates 601 are adapted to the corresponding sliding grooves 8 and rectangular grooves, which facilitates the stable operation of the installation component 6.

[0021] In this embodiment, during use, pulling the pull plate 601 causes the connecting shaft 602 to slide within the rectangular groove. The fixing plate 603 on the connecting shaft 602 slides synchronously within the slide groove 8, compressing the first spring 609. Simultaneously, the first inclined block 604 at the end of the connecting shaft 602 also moves. During the movement of the first inclined block 604, it presses against the second inclined blocks 605 on both sides, causing the second inclined blocks 605 to drive the connecting plate 606 to slide along the guide rod 608. At this time, the second spring 610 is compressed, the two sets of connecting plates 606 move away from each other, and the insert block 607 disengages from both sides of the mounting block 5. Then, the mounting block 5 is placed into the placement groove 7 and the sliding groove 8. The pull plate 601 is released. Under the elastic force of the spring 609, the connecting shaft 602 drives the inclined block 604 to reset, and the spring 610 restores its deformation, pushing the two sets of connecting plates 606 closer to each other. The connecting plates 606 drive the insert blocks 607 to insert into the interior of both sides of the mounting block 5, thereby firmly installing the inner ring 2 on the thrust plate body 1. The positioning protrusions 4 on both sides of the thrust plate body 1 can cooperate with the corresponding structure in the engine during the installation process to play a positioning role and ensure that the thrust plate body 1 is installed in an accurate position. The multiple sets of elastic claws 3 on the inner side of the inner ring 2 can cooperate with the engine crankshaft and other components to further fix the inner ring 2 and prevent it from shifting during operation, ensuring the normal operation of the engine crankshaft. The structural design of the mounting component 6 and the setting of the positioning protrusions 4 and elastic claws 3 not only realize the quick and accurate installation of the inner ring 2 and the thrust plate body 1, but also effectively prevent installation errors.
