| 摘要 |
The aim of the invention is to obtain an efficient noise reduction on a balance shaft for a reciprocating piston engine provided with at least one balance weight (22), which is elastically connected to the balance shaft (21) by means of an elastic element (25), preferably made of plastic whose elasticity is gradually changing in a peripheral direction. An intermediary solid part (26) comprises a fixed connection (15) to the balance shaft (11) in the peripheral direction, the elastic part (31) being adjacent to the balance weight (22) |
