Benefits of technology

This new technology solves issues with traditional methods for mounting and maintaining an accurate measuring instrument called a tensioner' s barrel or blade holder. It uses specialized supports made from materials like composite rubber that are resistant against high pressures without losing their effectiveness due to factors such as temperature changes during use. These supports allow for flexibility in selecting various types of workpieces based upon specific needs. By combining these unique feature components into a symmetric framework, this innovation improves its overall performance and lifespan compared to previous designs.

Problems solved by technology

Technological Problem addressed in this patents relating to conventional methods of measuring linear acceleration values involves difficulty handling and maintaining accurate measurements despite the use of hydraulic airbags. Additionally, current standards require multiple components including steel structures like yokes and levers, making them expensive and prone to damage overtime.

Embodiment Construction

[0026] Specifically, the moment arm lever is supported stably in the form of a bridge through the central circular shaft support and the two sets of combined static pressure air bearings. When working, high-pressure gas is introduced into the bearing system made of dense microporous non-metallic materials, and the gas is evenly released through the dense micropores. The high-pressure gas in the tiny gap between the bearing cavity and the central shaft makes the entire arm lever in suspension state, while being stabilized to be confined to the center of the bearing, it can also ensure that there is extremely small frictional resistance when rotating around the central axis.

[0027] The combined static pressure air bearing support mechanism is generally used in a standard torque generating device. On the one hand, it can support loads such as the lever of the moment arm and the weight for generating torque, and on the other hand, it can also ensure that the force exerted on the lev

Abstract

The invention relates to a combined type aerostatic bearing support mechanism, and belongs to the technical field of torque metering calibration. For improving support mechanisms at the middle parts of force arm levers of traditional standard torque generation devices, the combined type aerostatic bearing support mechanism with a symmetric structure is adopted, so that a series of problems in thetraditional structure are overcome, and the characteristics of reducing the realization difficulty and fault rate and prolonging the service life are increased. Correspondingly, the combined type aerostatic bearing support mechanism is capable of improving the force arm levers into single-beam double-arm symmetric frame structures, so as to effectively ensure the measurement correctness of the force arm levers on the basis of reducing the lever processing and assembling difficulty.
