Shaft assembly with balance weight bonded to shaft member
A method for balancing a shaft assembly having a shaft member. The method can include providing a balance weight having a body portion that is formed of a material that permits transmission of ultra-violet (UV) light therethrough, the body portion having a perimeter; applying an UV light-curable adhesive to at least one of the balance weight and the shaft member; positioning the balance weight to the shaft member such that the UV light-curable adhesive is abutted to the balance weight and the shaft member; and transmitting UV light through the balance weight to cure at least a portion of the UV light-curable adhesive that is disposed inwardly of the perimeter of the body portion.
1. A method for balancing a shaft assembly having a shaft member, the method comprising:
providing a balance weight having a body portion that is formed of a material that permits transmission of ultra-violet (UV) light there through, the body portion having a perimeter;
applying an UV light-curable adhesive to at least one of the balance weight and the shaft member;
positioning the balance weight to the shaft member such that the UV light-curable adhesive is abutted to the balance weight and the shaft member; and
transmitting UV light through the balance weight to cure at least a portion of the UV light-curable adhesive that is disposed inwardly of the perimeter of the body portion.
2. The method of claim 1 , wherein the balance weight further comprises a weight portion that is formed of a material having a density that is greater than a density of the material from which the body portion is formed.
3. The method of claim 2 , wherein the weight portion comprises two or more discrete structures that are disposed in the material from which the body portion is formed.
4. The method of claim 3 , wherein the two or more discrete structures are formed as rods.
5. The method of claim 4 , wherein the rods are cylindrically shaped.
6. The method of claim 1 , further comprising:
providing a strip of balance weight material; and
cutting the balance weight from the strip of balance weight material.
7. The method of claim 6 , further comprising:
determining a magnitude of a correction mass that corrects an imbalance in the shaft assembly; and
determining a length of the strip of balance weight material that is needed so that the balance weight and the UV light-curable adhesive have a mass that is equal to the magnitude of the correction mass.
8. The method of claim 1 , wherein the material from which the body portion is formed is transparent.
9. The method of claim 8 , wherein the material from which the body portion is formed is clear.
10. A shaft assembly comprising:
a shaft member;
a balance weight having a body portion with a perimeter, the body portion being formed of a material that permits transmission of ultra-violet (UV) light there through; and
a UV light-cured adhesive that bonds the balance weight the shaft member, the UV light-cured adhesive being disposed inwardly of the perimeter of the body portion.
11. The shaft assembly of claim 10 , wherein the balance weight further comprises a weight portion that is formed of a material having a density that is greater than a density of the material from which the body portion is formed.
12. The shaft assembly of claim 11 , wherein the weight portion comprises two or more discrete structures that are disposed in the material from which the body portion is formed.
13. The shaft assembly of claim 12 , wherein the two or more discrete structures are formed as rods.
14. The shaft assembly of claim 13 , wherein the rods are cylindrically shaped.
15. The shaft assembly of claim 10 , wherein the shaft assembly comprises a first joint that is fixedly coupled to an end of the shaft member.
16. The shaft assembly of claim 10 , wherein the material from which the body portion is formed is transparent.
17. The shaft assembly of claim 16 , wherein the material from which the body portion is formed is clear.
