Abstract

CARB bearing is a kind of compact aligning roller bearing with internal contact and slightly curved surface, which is the most important breakthrough of bearing technology in rencent 50 years. CARB bearing’s special structural design make it has unique advantages, for example, reducing the mechanical structure size, reducing cost, extending bearing life, reducing noise, improving radial load capacity and high temperature stability, etc, so it is widely used in the manufacturing industry. CARB bearing’s roller is cylinder with arc, this unique structure is suitable for adopting cold rolling technology

Abstract

A prototype for multi-mode linear ultrasonic motor has been proposed and designed. It is designed using a combination of the first longitudinal and the first bending mode. The piezoelectric ceramics convert energy using the longitudinal d33 effect which allows an improved reliability, large vibration amplitudes and excellent piezoelectric coupling. The normal direction motion of the driving element is excited by the first longitudinal mode. The tangential direction motion of the driving element is excited by the first bending mode. The resulting displacement of the driving element is transmitted by the frictional force between the vibrator and the rail in a linear motion. The analysis on the modals of the composite vibrator by using the ANSYS finite element software has been presented in this paper. Finally, the vibrator structure of the motor and the motor's own structures are designed. The basic design is discussed and simulations are compared with the experimental results, the results show that the motor characteristics can be optimized for a particular task by choosing the appropriate operating parameters such as exciting voltage, exciting frequency and normal force.

24. The Effect of Milling Parameters and Nickel Content on Ni-Al-TiO2-B2O3 System during Mechanical Alloying

Author

Liu, Qi, Dong, Shi Jie, Guang, Xu, Sun, Shi Xuan, and Luo, Ping

Abstract

The effect of nickel contents and milling parameters on the preparation procession of TiB2-Al2O3 composite powders during the mechanical alloying (MA) was studied in this paper. Milling parameters have certain influence on the phase transformation of Ni-Al-TiO2-B2O3 system during mechanical processing. With the same milling parameters, the proper content of Ni can promote the reaction route and influence the microtopography of the products.
