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. A tool having a motor, the tool comprising:
a nose housing;
a housing including an aperture adapted to receive a fastener that is adapted to apply a clamping force to couple the nose housing to the housing;
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 the second side is adapted to be disposed proximal to the motor.
2. The tool of claim 1 , wherein the insert includes a chamfer at the first side.
3. The tool of claim 1 , wherein each of the nose housing and the insert is composed of a material resistant to creep and stress relaxation.
4. The tool of claim 1 , wherein each of the nose housing and the insert is composed of metal.
5. The tool of claim 1 , wherein the housing is composed of plastic.
6. The tool of claim 1 , wherein the fastener is threadably coupled to the nose housing.
7. The tool of claim 1 , further comprising a seal disposed between the insert and the head of the fastener.
8. The tool of claim 7 , wherein the seal is an O-ring.
9. The tool of claim 1 , wherein the insert includes a barb disposed on an exterior surface of the insert.
10. An insert adapted to be disposed in a housing aperture of a housing of a tool, the insert comprising:
first and second opposing sides, wherein the first side is adapted to be disposed proximal to a head of a fastener that applies a clamping force to couple a nose housing to the housing, and the second side is adapted to be disposed proximal to a motor of the tool;
an insert aperture extending through the insert and that is adapted to receive the fastener; and
an exterior surface corresponding to the housing aperture.
11. The insert of claim 10 , wherein the insert is bonded to the housing.
12. The insert of claim 10 , wherein the first side of the insert includes a chamfer.
13. The insert of claim 10 , further comprising a barb disposed on the exterior surface.
14. The insert of claim 10 , wherein the insert has a substantially circular cross-section.
15. The insert of claim 10 , wherein the insert is composed of a material resistant to creep and stress relaxation.
16. The insert of claim 10 , wherein the insert is composed of a metal material.
