Basically a rotary viscous damper slows down pivoting objects like LCD screens and toilet bowl lids so they don’t slam. We focus on engineering and manufacturing a Rotary Viscous Damper that has found it’s way into quite a few applications. I will refer to the technology as an RVD going forward. The technology we use is a thin film shearing technique to create a controlled, smooth feeling torque that lasts hundreds of thousands of cycles. The medium that we shear is a special high viscosity fluid which can withstand the shearing action and not breakdown. This technology can be embedded in a large footprint application but Mechanical Motion Technologies focuses on the slimline small diameter type of designs. Our web page at www.mmtech.us has some good pics. The vehicle we specialize in is a single axis pivotal hinge so that designers and engineers can embed them in lids, LCD screens, handles, protection lids, toilet seats, garbage can lids, cosmetic cases, aerospace components, advertising signs, automotive compartments, electronic storage compartments and medical devices. As the engineer I evaluate the description of the motion desired by the customer and then collaborate with them on the most economical way to achieve their final design. Sometimes a product designer knows the exact motion or lack of motion they desire but doesn’t know the mechanism needed to achieve it. We can help in that area by examining the technical requirements and calculating the forces involved and formulating a working breadboard for a proof of concept. Every case is different; there are situations where an RVD is not appropriate. Some designs require an RVD, some require a friction hinge or some require both with a slip clutch in one direction, just to name a few. The RVD provides a smooth rotating action to prevent slamming, also to smooth out vibrations. It does add a classy feel of elegance, if I may be so forward. In one design the consistent smooth, controlled action of the RVD was the heart and soul of the products top quality appeal. RVD and friction hinges can work together or in tandem but must be carefully engineered to the specific application.
