Abstract
The utility model relates to a water-cooled bearing box without lubricant leak, which comprises a bearing, a upper cover of a bearing seat, a lower cover of the bearing seat, an end cover of the bearing seat, a limit ring, a stopping nut, a screw bolt, a gasket, a water inlet and outlet pipe, a sealing ring, a hoisting ring, a lubricant level display hole, a vibration measurer hole, a thermometer hole and a surface platinum thermal resistor hole. The bearing box is characterized in that the upper cover of the bearing seat and the lower cover of the bearing seat are equally arranged along the main axis of a bearing seat; and comb teeth are arranged at the junction of the end cover of the bearing seat and a main shaft. The utility model has the advantages of convenient assembly and disassembly, good cooling effect, no lubricant leak and improvement on the service life of the bearing.
Description
Technical field
The utility model relates to a kind of zero leakage of oil water-cooling bearing box.
Background technique
The main shaft of large centrifugal fan will be born bigger load and high rotating speed at present, can produce high heat, so main shaft will with bearing housing need water cooling, because needing lubricant oil on the bearing housing is lubricated, and remove at bearing housing oil hole is arranged, outside the water cooling circulation canal, also to there be some that temperature is installed and take into account vibrometer installation eyelet, therefore leakage of oil takes place in present bearing housing easily, in case therefore bearing housing generation leakage of oil then have a strong impact on the proper functioning of large centrifugal fan needs a kind of almost oil tight water-cooling bearing box to satisfy the usage requirement of large centrifugal fan.
Summary of the invention
The purpose of this utility model is the problem that solves the existing leakage of oil of water-cooling bearing box of the medium-and-large-sized centrifugal blower of prior art, and a kind of zero leakage of oil water-cooling bearing box is provided.A kind of zero leakage of oil water-cooling bearing box of the utility model design, comprise bearing, bearing support loam cake, bearing support lower cover, bearing cover, limited ring, retaining nut, bolt and sealing gasket, turnover water pipe, seal ring, suspension ring, oil level display hole, vibrometer hole, thermometer hole, surperficial platinum thermoresistance hole, it is characterized in that: bearing support loam cake and bearing support lower cover are divided equally along the main axis of bearing support, are broach with the main shaft connecting part on the bearing cover.The utility model has the advantages that easy accessibility, good cooling results, and the leakage that can not produce lubricant oil, the working life of improving bearing.
Description of drawings
Accompanying drawing 1 is a structural representation of the present utility model, and accompanying drawing 2 is the generalized section of Fig. 1,
Below in conjunction with drawings and Examples the utility model is elaborated,
Embodiment
Comprise bearing 1, bearing support loam cake 2, bearing support lower cover 3, bearing cover 4, limited ring 5, retaining nut 6, bolt and sealing gasket 7, turnover water pipe 8, seal ring 9, suspension ring 10, oil level display hole 11, vibrometer hole 12, thermometer hole 13, surperficial platinum thermoresistance hole 14 among the figure, it is characterized in that: bearing support loam cake 2 and bearing support lower cover 3 are divided equally along the main axis of bearing support, are broach 16 with main shaft 15 connecting parts on the bearing cover 4.During use, connect turnover water pipe on turnover water pipe 8, rely on extraneous cooling water to enter in the bearing support bearing 1 cooling, and heat is taken out of from outlet pipe, bearing support loam cake 2 and bearing support lower cover 3 are divided equally along the main axis of bearing support and are convenient to dismounting, and are beneficial to water cooling.Since with the bearing cover 4 of main shaft 15 connecting parts on offer broach 16, therefore can improve greatly and prevent the seepage of lubricant oil along main shaft 15.
