Description

Technical Field

[0001] This utility model relates to the field of engine bearing technology, and in particular to a removable and maintainable engine bearing. Background Technology

[0002] In modern power systems, the engine, as a core component, directly determines the overall performance of the equipment through its operational stability and reliability. Bearings, as a critical friction pair between the engine crankshaft and the engine block, bear the important functions of supporting the crankshaft, reducing friction, and distributing loads. As engines develop towards higher power density, lighter weight, and longer lifespan, the working environment of bearings under complex conditions becomes increasingly harsh, subjecting them to multiple tests of high temperature, high pressure, high speed, and alternating loads. This leads to increasingly prominent problems of bearing wear and fatigue spalling failure. Against this backdrop, developing a detachable and maintainable engine bearing has significant practical importance and application value. By optimizing the bearing's structural design and adopting a detachable connection method, rapid replacement and maintenance of the bearing can be achieved. This not only effectively shortens engine downtime for maintenance and improves equipment efficiency but also reduces maintenance costs and extends engine lifespan. Furthermore, the detachable and maintainable bearing design also facilitates green maintenance and remanufacturing of engine components, meeting the current requirements of energy conservation, emission reduction, and sustainable development in the industrial sector. It plays a positive role in promoting the advancement of engine technology and industry development.

[0003] Currently, detachable and maintainable engine shafts on the market mainly consist of the bearing body and detachable connecting components. To address the issue of bearing wear, the industry has adopted various solutions. In terms of materials, researchers are constantly exploring new high-performance friction-reducing materials. For example, aluminum-based alloys improve hardness and wear resistance by adding rare earth elements; copper-based alloys reduce wear under high-temperature conditions due to their good thermal conductivity and anti-galling properties; and composite materials utilize the complementary advantages of different materials to enhance the wear resistance of the bearing surface. In terms of surface treatment technology, plating and spraying processes are used to form a protective layer on the bearing surface. Hard chrome plating can improve the surface hardness and wear resistance of the bearing and reduce the coefficient of friction. Thermal spraying of ceramic coatings can enhance the bearing's high-temperature resistance. While these surface treatments offer mild wear resistance, they increase production complexity and cost. Furthermore, the protective layer may detach under extreme conditions, leading to a recurrence of bearing wear issues. Traditional engine bearings typically employ an integral, fixed assembly method. When wear or burning failures occur, the repair process is extremely complex. On one hand, the assembly precision requirements between the bearing and the engine block and crankshaft are extremely high, and disassembly can easily damage other precision components, increasing repair costs and potentially affecting the overall engine performance due to assembly errors. On the other hand, replacing integral bearings often requires extensive engine disassembly, consuming significant manpower, resources, and time, greatly reducing equipment efficiency.
