Abstract

The invention relates to a storage acceleration test device of lubricating grease. The storage acceleration test device comprises a base, an upper cover, balls, guide standing columns and loading blocks and is characterized in that the base is provided with a lower ball track, the upper cover is provided with an upper ball track, the upper ball track and the lower ball track are in one-to-one correspondence, the interior of each of the upper ball track and the lower ball track is smeared with the lubricating grease, the balls are located between the upper ball track and the lower ball track, and the guide standing columns penetrate the base, the upper cover and the loading blocks and used for limiting. The storage acceleration test device has the advantages that the device can be equivalent to the mechanical environment of the lubricating grease in a rolling contact pair and the external storage environment of the lubricating grease, a large amount lubricating grease can be stored andused for the physical and chemical property detection of the lubricating grease, and the device is easy to produce, low in cost, easy to mount and the like.

Description

technical field [0001] The invention relates to a storage acceleration test device for lubricating grease, in particular to a storage device for accelerated testing for research on the storage performance of lubricating grease in aerospace servo systems. Background technique [0002] Servo mechanism is our country's general name for the subsystems of launch vehicle flight control actuators. Among them, the electromechanical servo system is a servo system that has developed rapidly in recent years, and has been verified by many successful examples. Due to the characteristics of electromechanical servo system without oil, high output power, fast response, and small size, it has broad development prospects. With the expansion of demand, the storage performance requirements of electromechanical servo systems tend to be stricter. How to use them without maintenance after long-term ground storage has become an urgent task. The storage of grease for transmission mechanisms in elect...
