Overhung Load Adaptors Help with Transition from Mechanical to Electric
With the ongoing trend to more electrified power, there are often challenges integrating mechanical components needed to transition the electric power into the equipment.
These challenges are even more prevalent in retrofit applications. Customization may be required to achieve proper fit, speed capacity, and other critical performance features.
Zero-Max Overhung Load Adaptors (OHLA) Provide Mechanical System Load Support and Contamination Protection
OHLAs provide both overhung radial and axial load support to protect electrified mobile equipment motors from heavy application loads, extending the lifetime of the motor and alleviating the cost of downtime both from maintenance costs and loss of production.
Electrified and partially-electrified Heavy-Duty Tractors benefit from mechanical load support, protecting the electric motors from radial and axial loads for a longer lifespan. OHLAs provide both load support and a contamination barrier to protect the motor against water, dirt, and debris.
OHLAs also provide a contamination barrier to protect the electrified system from harsh environments that may include water, dirt, abrasives, chemicals, and other invasive debris, which are often present in mobile equipment applications.
Zero-Max OHLAs are available in an extensive offering of standard models for typical applications, or customized designs to fit applications with unique requirements. Zero-Max notes that well over half of OHLA sales are for customized units.
Zero-Max has a newly expanded standard OHLA product offering, including Extra-Duty designs for extreme applications with high overhung load conditions, high speeds, and high torque loads.
Electrified Mobile Equipment can develop shaft misalignments due to changing load conditions and wear over time. CD Couplings compensate for parallel, angular, and axial shaft misalignments, while keeping sideloads to a minimum, resulting in reduced wear and extended lifetime for both the electric motors and driven components.
Zero-Max also has recently added Double-Male Shaft OHLAs which can handle high radial load capacity for pulleys to achieve belt ratios in applications, or axial loads for spindle-related uses, and are sealed for reliable use in the harshest applications.
In switching to electrified power, the electric motors may have traditional SAE mounting standards typically used on mobile equipment, but may also include NEMA standards, or other non-industry standard mounting dimensions and piloting features. Zero-Max can accommodate these non-SAE mounting challenges with modified / customized OHLA designs.
