Abstract
The utility model relates to the technical field of mechanical transmission devices, and especially relates to a low-noise air-cooling electric spindle. The electric spindle comprises a stator component, a rotor component, a rotor shaft, and a casing. The center of the casing is provided with the rotor shaft. The rotor shaft is provided with the rotor component. Two ends of the rotor shaft are respectively sleeved on a front bearing and a rear bearing. The front bearing and the rear bearing are respectively clamped in a front end and a rear end of the casing. The front end of the casing is connected with a seal cover. An elastic sealing gasket is disposed between the seal cover and the front bearing. The outer side of the casing is fixedly connected with an outlet box. An upper end of the casing is provided with an outlet hole which is communicated with the outlet box. The rear end of the casing is provided with an outlet hole which is communicated with an independent fan. The independent fan is connected with the rear end of the casing through screws. The inner side of the casing is fixedly connected with the stator component. The low-noise air-cooling electric spindle cools down by using the independent fan, and is characterized by low noise, low temperature rise, large power, and good cooling effect.
Description
Technical field
The utility model relates to a kind of mechanical driving device technical field, relates in particular to the air-cooled electric main shaft of a kind of low noise.
Background technology
Electricity main shaft is the new technology in machine tool field, machine tool chief axis and spindle motor being combined together in recent years.Along with the develop rapidly of electron controls technology, electric main shaft is applied widely at Digit Control Machine Tool.Electricity main shaft is a Major Machine Tool functional part of Digit Control Machine Tool.Electricity main shaft is taking high-frequency converter as power supply, the power source taking spindle motor as main shaft, the machine tool functional component that directly drives high-precision machine tool chief axis to combine together.Electricity main shaft is divided into the direct-connected two kinds of forms of built-in motor or individual motor and high-precision machine tool chief axis.Generally electric spindle motor adopts threephase asynchronous, by Frequency Converter Control Speed Regulation by Changing Frequency on Three phase Asynchionous Motor, make electric main shaft reach infinitely variable speeds, rotating speed can turn to hundreds of thousands up to several, so the quality of its cooling effect and minimizing shake the noise bringing, and are directly connected to the useful life of electric main shaft.
Summary of the invention
The technical problems to be solved in the utility model is: the in the situation that of high accuracy, high rotating speed, high load capacity, the cooling effect of original electric main shaft is poor, and the noise that vibrations bring is large, provides a kind of low noise air-cooled electric main shaft.
In order to overcome the defect existing in background technology, the utility model solves the technical scheme that its technical problem adopts: the air-cooled electric main shaft of a kind of low noise, comprise stator component, rotor part, armature spindle and casing, described casing center is provided with armature spindle, armature spindle is provided with rotor part, armature spindle two ends are enclosed within respectively on fore bearing and rear bearing, fore bearing and rear bearing are stuck in inside, casing front and back end, casing front end is connected with seal cover, between seal cover and fore bearing, be provided with elastic sealing gasket, casing outside is fixedly connected with outlet box, casing upper end is provided with wire hole and is communicated with outlet box, casing rear end arranges wire hole and is communicated with separate fan, separate fan is fixed with casing rear end and is connected by screw, internal side of shell is fixedly connected with stator component.
According to another embodiment of the invention, further comprise that described stator component is provided with thermistor, described wire hole adds dustproof fixing glue.
The beneficial effects of the utility model are: the air-cooled electric main shaft of this low noise adopts separate fan cooling, and separate fan adopts the aerofoil fan of direct current 24v power supply, 5000rpm, has low noise, low-temperature-rise, powerful feature.With respect to coaxial fan blades electricity main shaft, it is little that it has noise, the continual and steady feature of air quantity.Exchange 2800rpm aerofoil fan with respect to common 220v, it is large that it has air quantity, the power feature that significantly width improves.When use, fan must often leave, and can meet the demand of user to the high-power air-cooled electric main shaft of low noise.
Brief description of the drawings
Below in conjunction with drawings and Examples, the utility model is further illustrated.
