Hidden Dismantling Technician vs. The Perfect Anti-Loosening Partner: The Philosophy of Details on RV Gearbox Screws

Have you ever noticed that the screws on the input flange of an WMRV reducer gearbox always come with a flat washer and a spring washer? This seemingly simple combination is a key line of defense against the equipment's "invisible killer"—vibration.

Why them?

During worm reducer operation, continuous high-frequency vibration can subtly loosen the screws. Once loosened, it can lead to oil leaks, abnormal noises, and even transmission failure. The combination of the spring washer and the flat washer is designed for this purpose:

Flat Washer: Responsible for distributing pressure, protecting the precision flange surface from being damaged by the screws, and providing a flat base for the spring washer.

Spring Washer: Acts as an elastic guardian. The continuous rebound force generated after it is flattened can actively compensate for the preload loss caused by vibration, "locking" the screw in its original position.

A Protection of 1+1>2 Both are indispensable. Without the flat washer, the spring washer's effect is reduced and it can damage the flange; without the spring washer, the screw can only "passively take the hits" under vibration. Their combination achieves dynamic anti-loosening, ensuring a long-term stable connection.

Our Commitment: At WUMA Transmission, this is not just standard equipment, but a microcosm of our commitment to reliability. We meticulously select materials, precisely match them, and execute this detail with the most rigorous processes. Because we know that for a precision core like the RV reducer, ultimate reliability lies in the meticulous craftsmanship hidden in these minute details.

Protecting power begins with the dedication to every single screw.
