Schnorr Load Washers

Taking the form of a disc spring, a Schnorr load washer serves as a fastening solution intended to compensate for the loosening of screwed connections.

Designed to protect for bolt joints.

Schnorr load washers are conical shaped washers engineered for the protection of bolted joints by maintaining the load under the head of a bolted joint. Load washers have been specially developed for high-strength bolts of grades 8.8 – 10.9. The load of the washers have been matched to these bolts and are 70% to 90% of the standard bolt load in the flat state.

Product:

Disc springs

Application:

Dragonfly dual-quadcopter lander

Challenge:

NASA’s mission to explore the solar system delivers an 8-bladed rotorcraft to visit Saturn’s largest and richly organic moon, Titan. Dragonfly will sample and examine dozens of promising sites around Saturn’s icy moon and advance our search for the building blocks of life.

Solution:

Our disc springs are used to help provide much-needed stability during the landing phase of the mission. The assembly is mounted inside a swivel device that works to prevent any parachute spin being imparted onto the probe below. During the mission, the disc spring stack will be subjected to cryogenic temperatures of 63 K, (-210 degC). Product design and material selection are critical factors in mission success.
