Embodiment
With reference to Fig. 1, Fig. 2, belt reducer used for cooling tower is described further.
Shown in Figure of description 2, a kind of belt reducer used for cooling tower, comprise retarder body 1, transmission shaft 2 and bearing 3, the two ends of described transmission shaft 2 are rotated by bearing 3 and are arranged on retarder body 1, in the present embodiment, bearing 3(bearing 3 comprises outer ring 31, rolling element 32, retainer and inner ring 33) inner ring 33 to be set on transmission shaft 2 and to be fixedly connected with transmission shaft 2, the outer ring 31 of bearing 3 is connected with retarder body 1 internal fixtion, one end of described transmission shaft 2 is fixedly connected with belt pulley 4 so that motor is rotated by belt drives belt pulley 4, belt pulley 4 rotates and transmission shaft 2 can be driven to rotate, the other end is provided with the coupling shaft 5 for being fixedly connected with axial fan hub, coupling shaft 5 can be used for connecting fan wheel hub, axial fan hub can be driven to rotate when transmission shaft 2 is rotated, and then the blade (not shown) that the rotation drive of axial fan hub is connected with axial fan hub, described bearing 3 is arranged on the inner one end near belt pulley 4 of retarder body 1, the sidewall of described retarder body 1 near belt pulley 4 one end is provided with pump nozzle 6, described retarder body 1 is provided with the oil through 7 for being communicated with the rolling element 32 between the inner ring 33 of bearing 3 and outer ring 31 near one end of belt pulley 4, be provided with the circulation that supplying lubricating grease slowly flow on bearing 3 between described oil through 7 and bearing 3 and stitch 8, described pump nozzle 6 arranges the inlet of oil through 7.
In the present embodiment, circulation seam 8 is most of by outer ring 31 bumping post of bearing 3 near one end of bearing 3 by oil through 7, and oil through 7 has the sub-fraction gap be communicated between outer ring 31 and inner ring 33 to be formed.Because the outer ring 31 of bearing 3 is fixed on retarder body 1 keep motionless, the grease flow therefore flowed into from oil through 7 can not cause loss to during the outer ring 31 of bearing 3, and its lubricating grease is merely able to flow in bearing 3 from circulation seam 8.
Shown in Figure of description 2, described oil through 7 is made up of horizontal oil canal 9 and longitudinal oil canal 10, one end of described horizontal oil canal 9 to extend to outside retarder body 1 and is communicated with pump nozzle 6, the other end is communicated with one end of longitudinal oil canal 10 and forms L-shaped, and the other end of described longitudinal oil canal 10 extends to inside retarder body 1 and is communicated with circulation seam 8.Oil through 7 is arranged to by horizontal oil canal 9 and longitudinal oil canal 10 form in L-shaped, its objective is and be that oil through 7 from pump nozzle 6 grease up the sidewall of retarder body 1, and can not need to carry out grease up under outage state; In the present embodiment, its horizontal oil canal 9 is cylindrical with longitudinal oil canal 10.
The sidewall of described horizontal oil canal 9 is provided with thermal expansion part.Described thermal expansion part is copper pipe 11, and described copper pipe 11 is arranged in horizontal oil canal 9.Copper pipe 11 is embedded in horizontal oil canal 9, the passage 12 of supplying lubricating grease circulation is left at its copper pipe 11 center, when transmission shaft 2 high speed rotating band dynamic bearing 3 high speed rotating, friction generates heat for the inner ring 33 of bearing 3, rolling element 32 and outer ring 31, when heat is delivered to copper pipe 11, its copper pipe 11 expanded by heating, thus the lubricating grease in copper pipe 11 is extruded, make lubricating grease can receive extruding and flow to fast on rolling element 32 and play lubrication to bearing 3, thus bearing 3 can be worked under the state of lubrication, extend the working life of bearing 3.
Specific implementation process: first lubricating grease is joined in horizontal oil canal 9 by pump nozzle 6, again because be provided with copper pipe 11 in horizontal oil canal 9, therefore lubricating grease can flow in longitudinal oil canal 10 in the passage 12 of copper pipe 11, grease up is stopped until being full of by oil through 7 or being filled to some direct being flow in bearing 3 by circulation seam 8 of lubricating grease always, under normal circumstances, because circulation seam 8 is smaller, lubricating grease can not be flow in bearing 3 fast, make in bearing 3, to there will not be too much lubricating grease to cause unnecessary waste, and be subject to the circulation quantitative limitation of circulation seam 8, its lubricating grease can be trapped in oil through 7 and not need regular grease up, in the course of the work, lubricating grease can flow on the rolling element 32 of bearing 3 slowly, when transmission shaft 2 high speed rotating band dynamic bearing 3 high speed rotating, friction generates heat for the inner ring 33 of bearing 3, rolling element 32 and outer ring 31, when heat is delivered to copper pipe 11, its copper pipe 11 expanded by heating, thus the lubricating grease in copper pipe 11 is extruded, lubricating grease be squeezed and flow into fast in circulation seam 8, to lubricate the bearing 3 of quick rotation, ensureing that bearing 3 has enough lubricating grease to extend the working life of bearing 3.
The above is only preferred implementation of the present utility model, protection domain of the present utility model be not only confined to above-described embodiment, and all technological schemes belonged under the utility model thinking all belong to protection domain of the present utility model.It should be pointed out that for those skilled in the art, do not departing from the some improvements and modifications under the utility model principle prerequisite, these improvements and modifications also should be considered as protection domain of the present utility model.
