Abstract
A power tool includes a motor housing and a motor supported within the motor housing. The motor includes an output shaft defining an axis. The power tool also includes a bearing configured to support the output shaft for rotation about the axis, an end cap removably coupled to the motor housing, and a bearing retainer integrally formed with the end cap. The bearing retainer is configured to axially and radially secure the bearing to the end cap.
Claims21
A power tool comprising:
- a motor housing;
- a motor supported within the motor housing, the motor including an output shaft defining an axis;
- a bearing configured to support the output shaft for rotation about the axis;
- an end cap removably coupled to the motor housing;
- and
- a bearing retainer integrally formed with the end cap, the bearing retainer configured to axially and radially secure the bearing to the end cap.

A power tool comprising:
- a housing including a motor housing portion and a front housing portion coupled to the motor housing portion;
- a motor supported within the motor housing portion, the motor including an output shaft defining an axis;
- an end cap removably coupled to the motor housing portion opposite the front housing portion;
- a bearing configured to support the output shaft for rotation about the axis;
- an anvil extending from the front housing portion;
- and
- a drive assembly configured to convert torque from the output shaft into a striking rotational force on the anvil,
- wherein the end cap includes a bearing retainer with a first wall extending parallel to the axis and opposed second and third walls extending transverse to the axis,
- wherein the first wall engages a radial side of the bearing to radially secure the bearing, and
- wherein the second and third walls engage opposite axial sides of the bearing to axially secure the bearing.
7 more elements
A power tool comprising:
- a housing including a removable end cap;
- a motor supported within the housing, the motor including an output shaft defining an axis and having a helical pinion;
- a gear assembly including a plurality of helical planet gears meshed with the helical pinon such that rotation of the output shaft produces an axial force on the output shaft;
- and
- a bearing configured to support the output shaft for rotation about the axis,
- wherein the end cap includes a bearing retainer configured to secure the bearing to the housing against the axial force on the output shaft.
