Solution Overview
Problem
The production of multi-layer sliding bearings is complex and difficult due to existing methods, which hinder efficient manufacturing and durability.
Innovation Solution
A method involving a carrier body and a bearing body with surface structures, where the bearing body is pressed onto the carrier body, forming a positive locking connection through plastic deformation and surface features like undercuts or knurling, facilitated by magnetic forces and controlled temperature, to achieve a strong and durable connection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional multi-layer sliding bearing production methods are used, then the connection between carrier body and bearing body can be achieved, but the production process becomes complex and difficult
Solution Approach 1:
A surface structure is created on the carrier body connecting surface before the bearing body is applied. This preliminary action of creating undercuts and deformation patterns enables the bearing body to form a positive locking connection during pressing, simplifying the overall production process while ensuring reliable connection.
Solution Approach 2:
The bearing body material is selected to have lower strength than the carrier body material, allowing the bearing body to be plastically deformed during pressing. This parameter difference enables the material to flow into the surface structure undercuts, creating a firm positive locking connection through controlled deformation.
2Ease of manufacture
If the bearing body material is made softer for easier fitting, then material fitting becomes easier, but the connection strength may be reduced
Solution Approach 1:
The surface structure with undercuts is created in advance on the carrier body. When the softer bearing body material is pressed onto the carrier body, it plastically deforms and flows into these pre-formed undercuts, creating a positive locking connection that compensates for the softer material strength while maintaining ease of fitting.
Solution Approach 2:
The connection is strengthened by combining two materials with different strength properties - a stronger carrier body material and a softer bearing body material. The softer material deforms to lock into the carrier body's surface structure, creating a composite connection that leverages both materials' properties.

AI summary
A method for producing a multi-layer sliding bearing includes: —providing a carrier body with a carrier body connecting surface, a surface structure being formed on the carrier body connecting surface, and the carrier body on the carrier body connecting surface having a carrier body material with a carrier body strength; —providing a bearing body with a bearing body connecting surface, the bearing body on the bearing body connecting surface having a bearing body material with a bearing body strength; —applying the bearing body to the carrier body, a carrier body connecting surface being turned towards a bearing body connecting surface; —pressing the bearing and carrier bodies together, wherein the bearing body, on the bearing body connecting surface, is plastically deformed and forms a positive locking connection with the carrier body connecting surface from the effect of the surface structure of the carrier body connecting surface.
