Abstract

The invention discloses a rotating mechanism for liquid nitrogen transfusion. The rotating mechanism is composed of a mechanism main body assembly, a rotating body assembly and a rotating body flange assembly, wherein the mechanism main body assembly is composed of a mechanism main body, a handicraft installing sleeve, a main body flange, a low temperature wear-resisting sealing ring and a main body end face sealing ring, and the mechanism main body is used for supporting and fixing in the whole mechanism; the rotating body assembly is composed of a rotating body, a rotating body bearing sleeve, a rotating body end surface sealing ring and a rotating bearing, the rotating body assembly and a liquid nitrogen transfusion pipe can rotate together to realize the rotating function of the mechanism; and the rotating body flange assembly is composed of a loose flange, a rotating body moving sealing ring and a pressing sealing base, and the rotating body flange assembly is mainly used for sealing and fixing the rotating body assembly.

Description

technical field [0001] The invention relates to the field of gas conveying devices, in particular to a rotating mechanism for liquid nitrogen infusion, which conveys liquid nitrogen to relatively rotating equipment. Background technique [0002] At present, when the liquid nitrogen source and the required liquid nitrogen equipment are relatively static, the transportation method generally adopts vacuum pipelines, and the static infusion technology has become mature. If the liquid nitrogen source and the required liquid nitrogen equipment move relatively, the vacuum pipeline alone cannot meet the needs of the rotating equipment. For example, the cold source of the high and low temperature test equipment for the three-axis turntable is liquid nitrogen. The high and low temperature test chamber for the three-axis turntable is placed on a platform with two degrees of freedom rotating relative to the ground. One degree of freedom is to rotate parallel to the ground. The other de...
