Part of a complex ball Induction Hardening
Kang, Huang Yongcheng and other technology - Debate pour Lei Kin-TRANSACTIONS OF METERIALS Huangyong Cheng, Zheng Yu new,[link widoczny dla zalogowanych], WANG Ze-zhong, Yuan sequence brother, King Construction (1. Huazhong University of Technology Wuhan 430074, China; 2. Dongfeng Motor Co.,[link widoczny dla zalogowanych], Ltd. Shiyan, Hubei 442001) Abstract: High-Performance bearing alloy All0Sn3SiCu development. Basic grasp of the Al-Sn bearing alloy containing silicon a full set of production technology. Application of existing casting and rolling production equipment, through the process of optimization and adjustment of tile finished product with the rolling rate of 93% or more,[link widoczny dla zalogowanych], fatigue and the sapphire quite similar foreign products. Off t words: bearing alloys; composite rolling; fatigue strength; sapphire ring test Keywords: U465.2.06 Document code: A Article ID :1005-2550 (2004) 02-0031--03 with automotive industry the rapid development of different applications, different characteristics of the car engine on the car bearing material from the different performance requirements. Conventional Al-Sn bearing alloy 20SnCu (SAE783), poor wear resistance because of low fatigue strength, bearing in strengthening the application of the engine is limited 【. \engine bearing [I.2]. Datong Bearing Industry Co., Ltd. has developed a silicon tin in the bush, and by adding the right amount of iron alloy stick shaft to solve problems and to apply for a patent in China. As the Al-Sn bearing silicon alloy, inlaid in the matrix phase with the soft and hard tin eutectic Si phase, so that the alloy has both good surface properties (on the axis of compliance and foreign particles in particle inclusive), but also has excellent fatigue performance and wear and corrosion performance. particularly in the use of ductile iron crankshaft, due to hard particles in the eutectic alloy of silicon on the role of the crankshaft journal lapping and polishing,[link widoczny dla zalogowanych], greatly improved the resistance to abrasion performance 【, so with Si Al-Sn bearing alloy has become a research hotspot in the field. Currently, the low load engine bearing alloy material still A120SnCu based on silicon plus aluminum bearing alloy is very small. This paper focuses on description A110Sn3SiCu alloy and bearing rolling strip production technology research complex situation. Xinjiang Date received: 2oD3-o9 a l71 process is currently in the production of bearing strip, there are two processes. One is sintering powder metallurgy, and the other is a composite sheet rolling. metallurgy sintering process is mainly used for copper lead bearing alloy of lead and aluminum production, this process does not exist the proportion of cast alloy due to segregation. Fulmer Research Institute and the British company invented the Grameen Sears A120SnCu alloys, to further promote the process of cold rolling complex in the medium and low load bearing production of the engine. the 20th century, late 60s. UK 96% and 58% of diesel engine cars have adopted this bearing manufacturing process [ ,],[cold-rolled composite material flow chart. Huang Lan Zhu Ji Dong H Zhu H limonene! Lan Figure 1 alloy cold-rolled composite technology development (2) the process will be the traditional vertical magnetic field and transverse magnetic field of advanced induction heating technology is relatively together. success solve complex variable cross-section part of the heating problem is the development of induction heating magnetic field theory can be complex to other parts of the heat treatment process in the promotion. (3) developed a rectangular, circular composite structure quenching sensor, simple structure, manufacture, commissioning and easy maintenance. tapered part of complex design of the sensor provides an example. (4) thrust ball shot induction hardening of a reliable process parameters to produce quality parts to meet the requirements of drawings and relevant standards to meet the loading and use of requirements. (5) promote the use of the technology can greatly enhance the two-axle heavy vehicles the technology content of the system can also greatly enhance the use of spherical parts of the other car assembly technology content.
