Cooling chamber is provided between main shaft, coil rotor is provided with cooling chamber, coil rotor is provided with central axial through hole；Axle
Compacting device includes rack sleeve drive end bearing bracket, the tight cap of main spindle front bearing, rear bearing gland, sleeve rear end lid and the tight cap of rear bearing,
Volume protected from water is formed between rack sleeve drive end bearing bracket and main shaft and sleeve, water proof ring is provided with volume protected from water；Encoder component bag
Include pinion stand, gear encoder wheel wheel, encoder fluted disc and encoder case；Sleeve is provided with cooling liquid inlet and coolant goes out
Mouthful, cooling liquid inlet and cooling liquid outlet are connected to feed pathway and back flow channel, feed pathway and back flow channel with it is cold
But cavity forms interior cooling circulation, and cooling liquid inlet is connected with cooling pump.
As a further improvement on the present invention, water proof ring includes the first water proof ring, the second water proof ring and the 3rd water proof ring, the
Second water proof ring and the 3rd water proof ring are folded between main shaft and sleeve by one water proof ring.
As a further improvement on the present invention, the tight cap of belt pulley is provided between ring flange and main shaft.
As a further improvement on the present invention, gear encoder wheel is located between sleeve rear end lid and the tight cap of rear bearing.
The beneficial effects of the invention are as follows：It is reasonable in design, it is simple in construction, it is integrally cold to axle using coolant using interior circulation
But cool, realize temperature-controllable, and then machining accuracy is got a promotion, while service life increases, and saves energy consumption, improves effect
Rate.
