Insert for a power tool housing
Inserts disposed in a housing of a pneumatically or hydraulically powered tool having a motor adapted to rotate a drive lug in either of first and second rotational directions. The insert is composed of a material resistive to creep and/or stress relaxation. The insert contacts fasteners applying a clamping force to the tool and remove the housing from the load path of the clamping force, thereby reducing the possibility of fluid leaks.
1. An insert adapted to be disposed in a housing of a tool, wherein the housing is adapted to house a motor, and includes front and rear sides and an aperture disposed in the rear side that is adapted to receive the insert and a fastener that is adapted to extend through the aperture and couple a nose housing to the front side of the housing, the insert comprising:
opposing first and second sides, wherein the first side is adapted to be disposed proximal to a head of the fastener and at least a portion of the second side is adapted to abut the motor; and
an insert aperture extending through the insert and that is adapted to receive the fastener.
2. The insert of claim 1 , wherein the insert is adapted to be bonded to the housing.
3. The insert of claim 1 , wherein the first side of the insert includes a chamfer.
4. The insert of claim 1 , further comprising a barb disposed on an exterior surface of the insert.
5. The insert of claim 1 , wherein the insert has a substantially circular cross-section.
6. The insert of claim 1 , wherein the insert is composed of a material resistant to creep and stress relaxation.
7. The insert of claim 1 , wherein the insert is composed of a metal material.
8. A tool, comprising:
a motor;
an output lug operably coupled to the motor and adapted to apply torque to a work piece;
a nose housing, wherein the output lug extends outwardly from the nose housing;
a housing including front and rear sides and an aperture in the rear side that is adapted to receive a fastener to couple the nose housing to the front side of the housing, wherein the motor is disposed in the housing; and
an insert disposed within the aperture, the insert having opposing first and second sides, wherein the first side is adapted to be disposed proximal to a head of the fastener, and at least a portion of the second side is adapted to abut the motor.
9. The tool of claim 8 , wherein the insert includes a chamfer at the first side.
10. The tool of claim 8 , wherein each of the nose housing and the insert is composed of a material resistant to creep and stress relaxation.
11. The tool of claim 8 , wherein each of the nose housing and the insert is composed of metal.
12. The tool of claim 8 , wherein the housing is composed of plastic.
13. The tool of claim 8 , further comprising a seal disposed between the insert and the head of the fastener.
14. The tool of claim 13 , wherein the seal is an O-ring.
15. The tool of claim 8 , wherein the insert includes a barb disposed on an exterior surface of the insert.
