What It Is
The Big Wheel in a rotary hammer is typically a large internal gear or pulley‑type component that plays a role in transmitting motion within the tool’s internal gear train.
In power tools like the RH150028, a “wheel” part often refers to a gear wheel that interfaces with other gears or mechanical assemblies to transfer torque from the motor to the hammering and drilling mechanisms.
Function in the Tool
Acts as part of the internal geartrain that translates the motor’s rotation into driving force for hammering and drilling.
Works with adjacent gears, shafts, and bearings to ensure smooth power transmission.
May help reduce or change rotational speed and torque between components.
Supports synchronized movement of hammer and drill functions in multi‑mode rotary hammer systems.
