ANSWER:
Where space, mounting requirements or length of stroke rule out the clevis type mount,
then trouble can develop. Installation inaccuracy, subsequent wear of slide
bearings, or deflection under gravity and operating loads can throw a heavy side load on
the cylinder rod as it passes through the gland.
Results are likely to be:
- Binding of rod, with jerky action or stalling under
load.
- Excessive wear of gland, causing breaks
- Excessive downtime
The Gagne Rod-End Coupling is designed to correct
this problem at the source by transmitting the push-pull cylinder force, but relieving all
side forces (under usual conditions). Lateral Displacement: The Coupling is designed
to accept up to 1/32 inch error in the smaller sizes, more in the larger sizes.
Angular Displacement: The Coupling will operate freely even though misaligned as much as 1
degree.
 A
Rod-End Free-Aligning Coupling is recommended at "x" (see picture) to minimize
likelihood of rod binding, jerky action and excessive gland and rod wear. |
COSTS:
Many designers recognize this 4-bearing problem
during design and provide their own special automatic adjusting device. But costs of
the "homemade" product will include some or all of these factors:
Costs eliminated by purchasing couplings:
- Design and detailing time
- High shop costs for a custom machined device
- Excessive debugging and maintenance if the new
design has been less than perfect
- Downtime costs
