| 1 | 一种具有仿生非光滑表面的高速列车车轮 | CN201510908455.8 | 2015-12-09 | CN105480012A | 2016-04-13 | 张国耕; 宋小文; 张鸣晓; 王耘; 黄长林; 胡树根 |
| 本发明公开了一种具有仿生非光滑表面的高速列车车轮，所述车轮踏面表面上通过激光毛化工艺制作有规则布置的凹坑状或者沟槽状仿生单元体。该车轮通过设置仿生的非光滑结构，具有降低列车车轮与轨道间噪声、增强耐磨性、抗机械疲劳的特点。本发明相对于现有技术，能有效的降低轮轨间噪声，提高列车车轮的抗机械疲劳性能以及耐磨损性能。 | ||||||

| A pulley assembly having a body, a shaft mount and a plurality of bolts is disclosed. The body is aligned to the shaft mount by providing a tight tolerance between a shoulder portion of the bolt and a neck portion of a counter sunk hole formed in the body. Additionally, an outer surface of the body may have a pattern of friction lines or patches formed by fusing particulate matter to the outer surface with heat generated by a laser beam. | ||||||
