摘　　要：提出了一种齿轮齿条机构产生匀速往复直线运动并能克服死点的方法。产生匀速连续往复运动是基于齿轮齿条传动具有恒定传动比的特性。齿轮齿条机构由一个主动不完全齿轮、2个标准从动齿轮和2个从动齿条组成,不完全主动齿轮的连续转动被转化成2个从动齿条的匀速往复直线运动。这种齿轮齿条机构已被具体应用于仿生鱼尾推进船模的设计与制造,通过船模试水验证其功能是有效可靠的。A method to develop a reciprocating linear translation with uniform moving velocity was provided. The mechanism is made up of gear and gear rack can get rid of dead point. The reciprocating continuous uniform motion is developed based on the character of uniform transmission ratio of gear and gear rack transmission. The provided mechanism consists of an incomplete driving gear, two normal driven gears and two driven gear racks. The incomplete driving gear continuous movement was translated the two driven gear racks reciprocating hnear uniform moving. The provided gear and gear rack mechanism have been used to designing and manufacturing ship model pushed with imitating fish - tail, and has been tested reliable and useful by moving on water.
