Vane Rotary Dampers The Design Requirements

It is generally desirable to design such a Vane Rotary Dampers. On the other hand must also produce a certain braking torque. Various designs have been proposed so that the braking torque is increased as much as possible, for example, Vane Rotary Dampers designing the cut surface of the viscous medium as large as possible. Such as connecting a plurality of sleeve sections and housings of the rotor in an alternating manner.

Adhesive viscous media can cause some problems, Vane Rotary Dampers and for most rotary dampers, the viscous medium is filled during the assembly of the damper. In most cases, Vane Rotary Dampers the end face seal plate constitutes an end seal. This type of charging can not be used for rotary dampers that must be filled after assembly (eg rotary dampers for the mandrel or shaft from both sides). For these dampers, Vane Rotary Dampers it is also conceivable to form an annular seal on the end face. However, Vane Rotary Dampers this is difficult to achieve due to the small width of the annulus and other design reasons. In addition, viscous media must be introduced in a very accurate manner, otherwise the viscous medium will be squeezed out or too much air will be retained in the housing. These two points are considered to be shortcomings, as this may result in contamination or failure of the required torque due to the presence of air.

It is therefore an object of the present invention to provide a rotary damper which is constructed so that the viscous medium can be filled in a simple manner after the final damper is assembled and the sealing property of the medium can be maintained.
