Vibration isolation mount system (ISO)
View Patent ↗A power tool includes vibration isolation material positioned between an engine shroud and a drive shaft housing. The vibration isolation material isolates the drive shaft housing from engine vibration for radial, axial, and torsional movement without utilizing intermediate components.
1. A hand held power tool comprising:
a drive shaft housing;
a clutch housing having an aperture therein; and vibration isolation material positioned between the drive shaft housing and the clutch housing, the vibration isolation material comprising a locator component and a main body portion; wherein,
the locator component projects into the aperture in the clutch housing; wherein the locator component includes an aperture that extends through the main body portion of the vibration isolation material; and wherein,
the main body portion is positioned adjacent the drive shaft housing.
2. The handheld power tool of claim 1 , wherein one end of the main body portion includes a radially inward facing flange.
3. The handheld power tool of claim 2 , wherein the radially inward facing flange abuts an end of the drive shaft housing.
4. The handheld power tool of claim 1 , wherein one end of the main body portion includes a radially outward facing flange.
5. The handheld power tool of claim 4 , wherein the radially outward facing flange abuts an end of the clutch housing.
6. The hand held power tool of claim 1 , wherein the locator component is a cylindrical structure having an outer diameter that corresponds with an inner diameter of the aperture in the clutch housing.
7. The handheld power tool of claim 1 , wherein the locator component aperture is adapted to receive a fastener.
8. The handheld power tool of claim 7 , wherein the locator component aperture is aligned with a bore provided in the drive shaft housing so that the fastener can extend through both the locator component aperture and the bore to prevent rotation of the vibration isolation material and the drive shaft housing with respect to each other.
9. The handheld power tool of claim 1 , wherein the main body portion is positioned adjacent the clutch housing.
10. An assembly method for a handheld power tool, the method comprising:
providing a drive shaft housing;
providing a clutch housing having an aperture therein;
positioning vibration isolation material between the drive shaft housing and the clutch housing, the vibration isolation material comprising a locator component and a main body portion; and
providing the locator component with an aperture that extends through the main body portion of the vibration isolation material; wherein,
the locator component projects into the aperture in the clutch housing; and wherein,
the main body portion is positioned adjacent the drive shaft housing.
11. The method as set forth in claim 10 , wherein the method further comprises providing a radially inward facing flange at one end of the main body portion.
12. The method as set forth in claim 11 , wherein the method further comprises abutting the radially inward facing flange to an end of the drive shaft housing.
13. The method as set forth in claim 10 , wherein the method further comprises providing a radially outward facing flange at one end of the main body portion.
14. The method as set forth in claim 13 , wherein the method further comprises abutting the radially outward facing flange to an end of the clutch housing.
15. The method as set forth in claim 10 , wherein the method further comprises providing the locator component as a cylindrical structure having an outer diameter that corresponds with an inner diameter of the aperture in the clutch housing.
16. The method as set forth in claim 10 , wherein the locator component aperture is adapted to receive a fastener.
17. The method as set forth in claim 16 , wherein the method further comprises aligning the locator component aperture with a bore provided in the drive shaft housing so that the fastener can extend through both the locator component aperture and the bore to prevent rotation of the vibration isolation material and the drive shaft housing with respect to each other.
18. The method as set forth in claim 10 , wherein the method further comprises positioning the main body portion adjacent to the clutch housing.
