Abstract
The utility model discloses a novel cooling cycle channel and sealing channel combined structure for an electric spindle. The combined structure comprises a sleeve arranged on the electric spindle in a sleeving manner; an air channel is formed inside a radial wall surface of the sleeve; a circulating groove is formed in the outer surface of a radial wall surface of the sleeve; a cooling liquid inlet is formed in one end of the circulating groove, and a cooling liquid outlet is formed in the other end; the circulating groove, the cooling liquid inlet and the cooling liquid outlet form the cooling cycle channel; and the air channel and the cooling cycle channel are mutually isolated. According to the combined structure, functional combination of cooling and sealing are finished on the same part, the cooling cycle channel is unimpeded and has small resistance, so that no stagnant water area is formed; air-tight seal and circulating water channels are formed independently at the same cross section; and further, the whole configuration is attractive, and pipeline connection of the complete machine is facilitated.
Description
Technical field
The utility model relates to a kind of electric Spindle's cooling structure.
Background technology
The electricity main axle structure is compact, and relative volume is little, and rotating speed is high, power is large, and environment for use is poor, and the heating of its stator coil and bearing is larger.
The utility model content
Compact for solving electric main axle structure, relative volume is little, and rotating speed is high, power is large, and environment for use is poor, the problem that the heating of its stator coil and bearing is larger, the utility model design novel cooling circulation canal of a kind of electric main shaft and seal channel combining structure.
The purpose of this utility model is come specific implementation by the following technical programs:
The electricity novel cooling circulation canal of main shaft and seal channel combining structure, comprise the sleeve that is socketed on electric main shaft, the radially wall inside of described sleeve is provided with the gas passage, the outer surface of the radially wall of described sleeve is provided with circulation groove, an end in circulation groove is provided with the cooling fluid entrance, the other end is provided with cooling liquid outlet, consists of the cool cycles passage by circulation groove, cooling fluid entrance and cooling liquid outlet, isolation mutually between described gas passage and cool cycles passage.
Described circulation groove is the S shape.
The utility model is completed cooling on Same Part and is sealed two function combinations.The unimpeded resistance of cool cycles passage of the present utility model is little, can not form dead water region; Form by one's own efforts hermetic seal and circulating water channel on same cross section; Make electric main shaft monnolithic case structure attractive in appearance, be convenient to the complete machine pipeline and connect.
Description of drawings
The below is described in further detail the utility model according to drawings and embodiments.
Fig. 1 is the unfolded surface structure chart of the novel cooling circulation canal of the described electric main shaft of the utility model embodiment and seal channel combining structure.
Fig. 2 is A-A cross-sectional view in Fig. 1.
The specific embodiment
As shown in Fig. 1-2, the novel cooling circulation canal of the described electric main shaft of the utility model embodiment and seal channel combining structure, comprise the sleeve 1 that is socketed on electric main shaft, the radially wall inside of described sleeve 1 is provided with gas passage 2, the outer surface of the radially wall of described sleeve 1 is provided with circulation groove 31, an end in circulation groove 31 is provided with cooling fluid entrance 32, the other end is provided with cooling liquid outlet 33, consist of cool cycles passage 3 by circulation groove 31, cooling fluid entrance 32 and cooling liquid outlet 33, isolation mutually between described gas passage 2 and cool cycles passage 3.
Described circulation groove 31 is the S shape.
The utility model is completed cooling on Same Part and is sealed two function combinations.The unimpeded resistance of cool cycles passage of the present utility model is little, can not form dead water region; Form by one's own efforts hermetic seal and circulating water channel on same cross section; Make electric main shaft monnolithic case structure attractive in appearance, be convenient to the complete machine pipeline and connect.
