Abstract
A motion conversion apparatus (100) comprises a rodrack assembly (110), which includes two guide members (140) and a first gear connection member (120) comprising opposing engaging arrangements (1201). The motion conversion apparatus (100) further comprises a gearshaft member (150) causing reciprocating linear motion of the rodrack assembly (110) along a reciprocation direction (D) by rotational motion of the gearshaft member (150). The gearshaft member (150) includes a second gear connection member (160) configured to engage with the first gear connection member (120), and a guiding surface arrangement (170) configured to contact a guide member (140) during rotational motion of the gearshaft member (150), wherein one gearshaft member (150) revolution causes a single period of reciprocating linear motion of the rodrack assembly (110). The guiding surface arrangement (170) contacts one of the two guide members (140) at an endpoint of the reciprocating linear motion of the rodrack assembly (110).
