Abstract

The invention discloses a heavy-load high-speed main shaft cooling device. The heavy-load high-speed main shaft cooling device comprises a main shaft, wherein a projected step section is arranged on one section of a driving end of the outer surface of the main shaft; a groove serving as an oil way is formed in the step section; a cooling sleeve coats the main shaft, and is connected with one section of a driven end of the main shaft through bearings; a spacing sleeve is arranged between the bearings and the step section; an oil inlet and an oil return port are formed in the outer surface of the cooling sleeve; the oil return port is connected with the groove of the step section of the main shaft; at least two bearings are provided; a ring sleeve with an oil hole is arranged between the two bearings; and the oil inlet is connected with a gap between the bearings through the oil hole of the ring sleeve. Compared with the prior art, the heavy-load high-speed main shaft cooling device can solve the problem of influence on the acceleration of rotating speed due to weak cooling lubrication of a traditional heavy-load main shaft.

Description

technical field [0001] The invention relates to the technical field of engineering machinery processing, in particular to a cooling device for heavy-duty high-speed spindles of large-scale machinery. Background technique [0002] Due to the large size and weight of the existing large-scale machinery and heavy-duty spindles, and to ensure good coaxiality, natural cooling and grease lubrication are generally used, that is, the spindles are cooled by natural wind, and the outer surface of the spindles is cooled. Regularly inject lubricating oil to lubricate and cool. This kind of lubrication method is simple and easy to operate, and does not require additional equipment. Its disadvantage is that the applicable speed is low. At the same time, because no special cooling measures are used, it also brings difficulties to further increase the spindle speed. Spindle cooling and lubrication has become one of the technical bottlenecks in this industry. Contents of the invention [...
