摘要
本文推导了单万向联轴机构中的通用瞬时传动比公式,并利用空间投影和运动学关系论证了新型双联同步万向联轴机构的安装条件和实现方法。新型机构大大扩充了现有设计资料所提供的双万向联轴机构的使用范围,对机械设计人员具有实用价值。
The formula of general momentary drive ratio is derived for a single universal coupling mechanism,and the installing condition and its imple- mentation are discussed for a new model of double synchronous universal coupling mechanism based on the relationship between perspective pro- jection and kinematics.The new mechanism enlarges the scope of use of the double universal coupling mechanisms available at the present time.
