Rotary impact tool with thrust bearing

A rotary impact tool comprising:

• a housing;
• a motor supported within the housing, the motor including a shaft configured to rotate about an axis;
• a gear assembly operably coupled to the motor, the gear assembly including a ring gear fixed relative to the housing and a plurality of planet gears meshed with the ring gear and rotationally engaged with the shaft such that the motor is configured to drive rotation of the planet gears around the ring gear via the shaft;
• a camshaft including a carrier portion that supports the planet gears such that the camshaft is configured to rotate with the planet gears about the axis;
• and
• a thrust bearing positioned between the camshaft and the ring gear.

A rotary impact tool comprising:

• a housing;
• a motor supported within the housing, the motor including a shaft configured to rotate about an axis;
• a gear assembly operably coupled to the motor;
• and
• a drive assembly configured to convert continuous torque received from the shaft through the gear assembly into periodic rotational impacts upon a workpiece, the drive assembly including
• a camshaft operably coupled to the gear assembly,
• an anvil,
• a hammer spring, and
• a hammer configured to reciprocate along the camshaft to impart rotational impacts to the anvil in response to rotation of the camshaft, wherein movement of the hammer produces an axial load on the camshaft;
• and
• a thrust bearing supporting the camshaft such that at least a portion of the axial load on the camshaft is transmitted through the thrust bearing.
