Låsemoment

Låsemoment, often translated as locking torque or holding torque, refers to the amount of rotational force a device can withstand before it begins to rotate or slip. This concept is crucial in mechanical engineering and is applied in various contexts, from fasteners like screws and nuts to rotational components in machinery.

In the context of fasteners, låsemoment is the torque required to overcome the friction and mechanical interlocking that prevents a nut or bolt from loosening due to vibration, thermal expansion, or external loads. Specialized locking mechanisms, such as lock washers, thread-locking compounds, or self-locking nuts, are designed to increase this låsemoment. The effectiveness of these mechanisms is often measured by their ability to maintain a sufficient låsemoment over time and under various operating conditions.

Beyond fasteners, låsemoment is also relevant to clutches, brakes, and rotational joints. For a clutch, it represents the maximum torque it can transmit without slipping. In braking systems, it relates to the torque the brake can apply to stop or hold a rotating component. The design and selection of components that rely on låsemoment are critical for ensuring the safety, reliability, and performance of mechanical systems. Understanding and calculating låsemoment helps engineers prevent unintended movement and failure.
