Abstract
A crankshaft assembly is provided. The crankshaft assembly includes a crankshaft including a first engaging member and a second engaging member. The second engaging member is spaced from the first engaging member in a direction of a rotational axis of the crankshaft. A first center point of the first engagement member is offset from a second center point of the second engagement member an offset angle defined about the rotational axis. The offset angle is 270°.

A handheld power tool, comprising:
- a first reciprocating element;
- a second reciprocating element;
- a crankshaft comprising a first engaging member and a second engaging member, the second engaging member spaced from the first engaging member in a direction of a rotational axis of the crankshaft;
- a first connecting rod extending between a first end and a second end opposite the first end, the first connecting rod coupled between the first engaging member of the crankshaft and the first reciprocating element;
- and
- a second connecting rod extending between the first end and the second end, the second connecting rod coupled between the second engaging member of the crankshaft and the second reciprocating element;
- wherein a first center point of the first engagement member adjacent the first end is offset from a second center point of the second engagement member adjacent the first end an offset angle defined about the rotational axis;
- and
- wherein the offset angle is greater than 180°.
