Description

Technical Field

[0001] The utility model relates to the technical field of low-temperature lubrication, in particular to a heating structure for lubricating grease used in a low-temperature environment. Background Art

[0002] In recent years, the demand for -80℃ ultra-low temperature sample libraries has increased significantly in national scientific research institutions and some local laboratories, mainly for the preservation of biological products, chemical reagents, plasma, vaccines, strains and biological samples. In ultra-low temperature automated storage equipment, bearings are essential transmission components, and the impact of low-temperature lubricating grease on bearings is extremely critical. The bearings in these automated sample libraries require a large amount of lubricating grease to complete their work in a -80℃ environment.

[0003] The lowest operating temperature of lubricating grease commonly used in the market is generally around -20°C, and the temperature of a small number of low-temperature greases can reach -40°C. Therefore, the technical solution provided by the utility model can well solve the application bottleneck of lubricating grease in a -80°C environment. Utility Model Content

[0004] In order to overcome the shortcomings of the above-mentioned prior art and solve the problem that the lubricating grease in the bearing easily loses viscosity in a low temperature environment, thereby affecting the lubrication effect, the utility model provides a heating structure for lubricating grease in a low temperature environment, and the specific technical solution is as follows:

[0005] A heating structure for lubricating grease in a low-temperature environment comprises a heating structure body, wherein the heating structure body comprises two semicircular arc fasteners with hollow interiors and an electric heating harness; both ends of the fasteners are bent inwards to form mounting ears; the electric heating harness is arranged at the edges of both ends of the fasteners, close to the mounting ears.

[0006] Preferably, the opening sides of the two fasteners are arranged opposite to each other.

[0007] Preferably, the fastener is made of stainless steel.

[0008] Preferably, the electric heating harness is made of mica material.

[0009] Preferably, a temperature-sensing switch is provided in the cavity of the fastener.

[0010] Also preferably, the temperature sensing switch is electrically controlled connected to the electric heating harness.

[0011] Also preferably, the mounting ears are provided with bolt holes.

[0012] Further preferably, the heating structure body is fixed on the inner side of a bearing of the low-temperature storage device.

[0013] More preferably, one end of the electric heating harness is fixed to a fastener, and the other end is a free end and contacts the bearing surface.

[0014] The beneficial effects of the utility model are:

[0015] 1. The utility model is fixed to the inner side of the bearing in the ultra-low temperature storage device by bolts, and adopts stainless steel fasteners and an electric heating harness made of mica material, so that the heat is directed to one side of the bearing in a single direction, and the grease in the bearing is heated so that it does not lose its viscosity, thereby ensuring the lubrication effect without affecting the sample storage.

[0016] 2. The utility model monitors the bearing temperature through a temperature-sensing switch. When the bearing temperature is higher than -10°C, the temperature-sensing switch automatically disconnects and stops heating, thereby avoiding a reduction in the refrigeration effect of the sample library due to excessively high bearing temperature.

[0020] The specific implementation manner of a heating structure for lubricating grease in a low-temperature environment provided by the utility model is further described in conjunction with the accompanying drawings and embodiments.

[0021] like Figure 1 As shown, a heating structure used for grease lubrication in a low-temperature environment includes a heating structure body. When in use, the heating structure body can be fixed on the inner side of a bearing member that needs lubrication in an ultra-low temperature storage device, which is convenient for disassembly and assembly.

[0022] Preferably, the heating structure body comprises two semicircular arc fasteners 1 with hollow interior and an electric heating harness 2. The two ends of the fastener 1 are bent inward to form mounting ears 3, and the mounting ears 3 are provided with bolt holes 31; the heating structure body is fixed to the inner side of the bearing of the low-temperature storage device through the mounting ears 4 and bolts;

[0023] Preferably, the electric heating harness 2 is arranged at the edges of both ends of the fastener 1, close to the mounting ear 3; it is worth noting that the electric heating harness 2 is fixed to the fastener 1, and the other end is a free end and contacts the bearing surface to achieve the purpose of heat conduction.

[0024] Preferably, the opening sides of the two fasteners 1 are arranged opposite to each other, and the fasteners 1 are made entirely of high-strength, corrosion-resistant stainless steel material.

[0025] Preferably, the electric heating harness 2 is made of mica material.

[0026] Preferably, a temperature sensing switch is provided in the cavity of the fastener 1, wherein the temperature sensing switch is electrically connected to the electric heating harness 2. When the inner surface temperature of the bearing is detected to be higher than -10°C, the temperature sensing switch is automatically disconnected, and the electric heating harness 2 stops heating, so as to avoid reducing the cooling effect of the sample library due to excessively high bearing temperature.

[0027] The utility model adopts an assembly method that combines a fastener made of stainless steel and an electric heating harness made of mica, so that heat can be directed to one side of the bearing in a single direction to heat the grease in the bearing so that it does not lose its viscosity, thereby ensuring the lubrication effect without affecting sample storage and extending the service life of the equipment bearing.

[0028] Furthermore, the utility model has a simple structure, is easy to install, has a low cost and is easy to maintain.
