ABSTRACT:
A pendulous type of accelerometer is disclosed herein and includes a sealed housing defining an oil filled internal chamber, a pendulous member located within the housing chamber and a pair of bearing mechanisms for pivotally supporting the pendulous member. The accelerometer also includes an assembly associated with each of the bearing mechanisms for preloading the latter, each of which includes two preload arrangements, a first or inner arrangement and a second or outer arrangement. The inner arrangement is provided for applying and adjusting a preload force against its associated bearing mechanism before the housing is assembled and its chamber is filled with oil and sealed and the outer arrangement is provided for further adjusting the applied preload force from outside the housing after the latter is assembled and its inner chambers filled with oil and sealed.
