Abstract
A motion conversion apparatus (400, 500) comprises at least one set including a rodrack assembly (110) between two gearshaft member end sections (155), and a gearshaft member mid section (156) between the two gearshaft member end sections (155). The rodrack assembly (110) comprises a first gear connection member (120) and two guide members (140). The gearshaft member mid section (156) comprises a second gear connection member (160) configured to engage with the first gear connection member (120). The two gearshaft member end sections (155) each comprise a guiding surface arrangement (170) configured to contact the two guide members (140). The rodrack assembly (110) is configured to provide rotation of the gearshaft member mid section (156) about a rotational axis (A) by reciprocating linear motion of the rodrack assembly (110) along a first spatial dimension (D1) orthogonal to the rotational axis (A), or vice versa.
