Description

Technical Field

[0001] This utility model relates to the field of diesel engine flywheel technology, specifically a diesel engine flywheel with a self-lubricating structure. Background Technology

[0002] A diesel engine flywheel is an energy storage component that stores the engine's kinetic energy through gravity and inertia, ensuring stable engine operation. The flywheel's main functions include storing and releasing energy, ensuring smooth engine operation, assisting with starting, and balancing vibrations.

[0003] According to a Chinese patent (CN209511006U), a diesel engine flywheel that is easy to disassemble and replace includes a flywheel disc. A boss is fixedly provided on the upper surface of the flywheel disc. A placement groove, a threaded hole a, an oil injection groove, and an oil guide groove are respectively formed on the outer side of the boss on the upper surface of the flywheel disc. A spring is fixedly installed in the placement groove, and the oil injection groove is semi-circular. When the gear ring needs to be replaced, the gear ring is first heated. After the gear ring cools down, the fixing bolt is rotated so that the fixing bolt is turned out from the threaded holes a and b. Lubricating oil is then injected into the contact part between the gear ring and the flywheel disc through the oil injection groove and the oil guide groove. Finally, a wedge or other tool is used to wedge into the disassembly groove, and then the wedge is struck to easily remove the gear ring. The placement groove contains a spring, which makes it easier and faster to remove the gear ring. The design of the oil injection groove and oil guide groove, the spring, and the disassembly groove makes this invention easy to disassemble and securely install.

[0004] However, existing devices still have the following problems: traditional diesel engine flywheels require regular grease replenishment, resulting in high maintenance costs, and are prone to friction damage due to insufficient lubrication. Therefore, a diesel engine flywheel with a self-lubricating structure is proposed. Utility Model Content

[0005] The purpose of this invention is to provide a diesel engine flywheel with a self-lubricating structure to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a diesel engine flywheel with a self-lubricating structure, including a flywheel disc;

[0007] A gear ring that is fixedly fitted onto the surface of the flywheel;

[0008] A boss is fixedly connected to the front of the flywheel, with a through hole and three heat dissipation holes on the front of the boss.

[0009] It also includes multiple threaded holes through the front of the flywheel, and a lubrication assembly is provided on the inner side of the flywheel.

[0010] Preferably, the lubrication assembly includes an annular groove extending through the rear side of the flywheel disc, a hollow groove extending through the bottom surface of the annular groove, an oil storage hole extending through the rear side of the hollow groove, a connecting groove extending through the rear side of the oil storage hole, a capillary micropore extending through the rear side of the flywheel disc, the inner wall of the capillary micropore communicating with the inner wall of the connecting groove, a conical bucket fixedly connected to the inner wall of the connecting groove, the inner wall of the capillary micropore communicating with the inner wall of the conical bucket, and the diameter of the conical bucket being larger than the diameter of the capillary micropore.

[0011] Preferably, the rear side of the flywheel is set as a flat surface.

[0012] Preferably, the spacing between one of the multiple threaded holes and its adjacent threaded holes is different, while the spacing between the remaining adjacent threaded holes is the same, which facilitates the positioning and installation of the flywheel disc.

[0013] Preferably, the oil storage hole is configured as a honeycomb oil storage hole, which can be used for storing high viscosity, high temperature resistant grease.

[0014] Preferably, the diameter of the capillary micropores is no greater than 0.1 mm, effectively blocking the intrusion of external dust.

[0015] Preferably, the rear end face of the flywheel is coated with a polytetrafluoroethylene coating, which can reduce the friction of the flywheel and prevent the grease from evaporating.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] 1. This diesel engine flywheel with a self-lubricating structure can automatically release high-viscosity, high-temperature resistant grease stored in the oil reservoir through centrifugal force when the flywheel disc rotates, thereby lubricating the contact surface of the flywheel disc. This effectively avoids the tedious steps of regularly adding grease to traditional diesel engine flywheels, thus significantly reducing maintenance costs.

[0018] 2. The diesel engine flywheel with a self-lubricating structure can continuously lubricate and protect the friction surface of the flywheel disc through the lubrication components, reducing friction damage caused by insufficient lubrication, which not only improves the operating efficiency of the flywheel, but also significantly extends its service life.

[0019] 3. The diesel engine flywheel with a self-lubricating structure has capillary micropores in the lubrication components with a diameter of no more than .mm. This design effectively prevents the intrusion of external dust, keeps the internal lubrication environment of the flywheel disc clean, and further ensures the stable operation of the flywheel.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Example 1: Please refer to Figure 1 - Figure 5 This utility model provides a technical solution: a diesel engine flywheel with a self-lubricating structure, including a flywheel disc 1;

[0028] A gear ring 2 is fixedly fitted onto the surface of the flywheel disc 1;

[0029] A boss is fixedly connected to the front of the flywheel, with a through hole 5 and three heat dissipation holes 3 through the front of the boss.

[0030] And multiple threaded holes 4 are opened through the front of the flywheel 1, and a lubrication component 60 is provided on the inner side of the flywheel 1.

[0031] Lubrication assembly 60 includes an annular groove 601 extending through the rear side of flywheel 1. A hollow groove 602 extends through the bottom surface of the annular groove 601. An oil reservoir 603 extends through the rear side of the hollow groove 602. A connecting groove 604 extends through the rear side of the oil reservoir 603. A capillary micro-hole 606 extends through the rear side of the flywheel 1. The inner wall of the capillary micro-hole 606 communicates with the inner wall of the connecting groove 604. A conical hopper 605 is fixedly connected to the inner wall of the connecting groove 604. The inner wall of the capillary micro-hole 606 communicates with the inner wall of the conical hopper 605, and the conical hopper 605 has a large diameter. With a diameter of 606 micropores, the lubrication component 60 allows the high-viscosity, high-temperature resistant grease stored in the oil reservoir 603 to seep out automatically using centrifugal force when the flywheel disc 1 rotates, thus lubricating the contact surface of the flywheel disc 1. This effectively avoids the tedious step of regularly adding grease to the flywheel of a traditional diesel engine, thereby significantly reducing maintenance costs. Through the lubrication component 60, the friction surface of the flywheel disc 1 can receive continuous lubrication protection, reducing friction damage caused by insufficient lubrication. This not only improves the operating efficiency of the flywheel but also significantly extends its service life.

[0032] The rear side of flywheel 1 is set to be a flat surface.

[0033] The spacing between one of the multiple threaded holes 4 and its adjacent threaded holes 4 is different, while the spacing between the remaining adjacent threaded holes 4 is the same. This facilitates the positioning of the flywheel disk 1 during installation, improving the convenience and accuracy of installation.

[0034] The oil storage hole 603 is designed as a honeycomb oil storage hole.

[0035] The capillary micropores 606 have a diameter of no more than 0.1mm, which effectively prevents the intrusion of external dust, keeps the internal lubrication environment of the flywheel disc 1 clean, and further ensures the stable operation of the flywheel.

[0036] The rear end face of the flywheel disc 1 is coated with a polytetrafluoroethylene (PTFE) coating. The PTFE coating not only reduces the friction of the flywheel disc, but also prevents the evaporation of lubricating grease, thereby further enhancing the performance and stability of the flywheel.

[0037] In use, high-viscosity, high-temperature resistant grease is added to the annular groove 601. After passing through the empty groove 602, the high-viscosity, high-temperature resistant grease enters the oil reservoir 603, which stores the grease. The flywheel 1 is installed through the screw and threaded hole 4. During the installation of the flywheel 1, the spacing between the different threaded holes 4 is adjusted. When the flywheel 1 rotates, it is driven by centrifugal force. The high-viscosity, high-temperature resistant grease inside the oil reservoir 603 enters the connecting groove 604 and then enters the capillary pores 606 through the conical hopper 605. This allows the high-viscosity, high-temperature resistant grease to seep out and lubricate the contact surface of the flywheel 1. The higher the rotational speed of the flywheel 1, the greater the amount of high-viscosity, high-temperature resistant grease seeping out driven by centrifugal force.

[0038] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to the embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
