Abstract

The invention discloses a tool for bearing liquid nitrogen refrigeration, which includes a liquid nitrogen conveying device, a bearing tool casing, a refrigeration sleeve, a bearing, a rotary base anda measurement observation device, wherein the liquid nitrogen conveying device is connected with the bearing tool casing on the lower side through a liquid conveying pipe; the inner side of the bearing tool casing is connected with the refrigeration sleeve through the liquid conveying device; the refrigeration sleeve is divided into two parts, namely a first refrigeration half pipe and a second refrigeration half pipe respectively; the first refrigeration half pipe and the second refrigeration half pipe are connected through a fixator; a bearing is arranged on the inner side of the refrigeration sleeve; the bottom of the bearing is detachably embedded on the rotary base; the measurement observation device is arranged on the rotary base. According to the invention, a nitrogen device and apressure device of the liquid nitrogen conveying device are used for liquefying nitrogen, and then liquid nitrogen is conveyed by the liquid conveying device to the refrigeration sleeve, then a cooling sprayer is used for uniformly cooling the inner side bearing, and the cooling efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of bearing tooling equipment, in particular to a tooling used for bearing liquid nitrogen freezing. Background technique [0002] In the process of mechanical assembly, the assembly of bearings sometimes needs to be cooled by liquid nitrogen freezing, which has achieved the purpose of reducing the size of the bearings and facilitates installation. After installation, the bearings can be achieved through thermal expansion and contraction In the normal temperature state, the volume becomes larger, so as to achieve the purpose of improving the stability of the bearing. [0003] However, the currently used bearing liquid nitrogen freezing tool generally adopts the purpose of inputting liquid nitrogen from one side when cooling the bearing, and the cooling is uneven, resulting in a slower cooling speed of the bearing; and usually, after cooling is completed, use The liquid nitrogen afterward is generally wasted....
