Railroad Motor Mount
Adapter Frame
PIAD Precision Casting Corp.

| Material: |
Nickel aluminum
bronze. |
| Process: |
Permanent mold. |
| Size: |
16.44 lb; 14.4 x 7.12
x 7.31 in. |
| Application: |
The component
supports the motor and clutch in a railroad track-switching
machine. |
| Converted From: |
Welded fabrication. |
|
 |
- Originally, the part was made from
10 fabricated and machined components requiring 20 weld joints, 24
machining operations, dichromating and two painting processes. The
bottom plate was machined from a 1-inch thick steel plate (1020 cold
steel) that required an additional 12 machining operations. By
converting to a cast component, the customer realized a 29% weight
reduction and significant cost savings.
- The nickel aluminum bronze material
exceeds the strength of 1020 steel with 51 ksi yield and 95 ksi
tensile strength.
- The redesign to a nickel aluminum
bronze casting provides a near-net-shape component and eliminates the
need for secondary dichromating and painting. In addition, the
one-piece casting eliminates 20 weld joints, reducing warpage due to
welding, and increases part functionality.
