Transportation
For the high stress requirements of automotive, locomotive,
trucking, and heavy equipment components, BelleFlex ball bearing disc
springs are an excellent choice. Bellevilles are widely used in
hydraulics, brake assemblies, train trucks, clutches, and transmissions,
among other components. Some applications in the transportation
industry may use radial ball bearings. The rolling elements of radial
ball bearings roll on two races, an outer race and an inner race. The
use of Bellevilles to pre-load radial ball bearings helps to maintain
position and minimize vibration by distributing the load evenly around
the bearing race. Shaft end play can undermine the performance of
the ball bearing application. The addition of properly pre-loaded
Bellevilles helps to eliminate shaft end play and increase application
life. A BelleFlex ball bearing disc spring can be designed so that the
outside diameter and the inside diameter of the spring exert pre-load on
the outer and inner races, even though the races have differently sized
ball bearings.
BelleFlex Belleville disc springs have a long life and are well-suited
to sealed applications, such as transmissions. Available in materials,
such as H13 Tool Steel, 300 Series Stainless Steel, and INCONEL
Alloys, BelleFlex Bellevilles can withstand high temperatures, frequent
cycling, and high loads. We also produce custom Bellevilles, which are
used in the automotive industry. |
