Abstract
The name of the utility model is an electric main axle, belonging to the bearing grinding process technical field, which mainly solves the problems of the prior electric main axle: small power (15-20kw), low efficiency, bad water-proof performance and high maintenance cost, characterized in that: the electric main axle comprises a rotor axle, an axle shell, an motor stator, a rotor, a support bearing, a labyrinth type water proof structure, a cooling system; wherein a water circulation groove of the cooling system is a spiral groove arranged on the inner wall of a shell adjacent to the stator; a water pushing groove is arranged at the part of the front end of the rotor axle opposite to the shell dust-proof cover; the structure size of the motor stator is Phi 130X137. The electric main axle has features of high highest rotation speed, large constant torque rotation-speed range, high rigidity, high speed, multi-level speed adjustment, small size of a built-in motor, good heat radiation effect, good water-proof sealing, stability and reliability and the electric main axle is mainly used for grinding and processing the bearing.
Description
Technical field
The utility model belongs to bearing mill processing technique field, is specifically related to the electric main shaft frock of a kind of bearing mill processing.
Background technology
The electricity main shaft is the main frock of bearing mill processing, and its precision and efficient directly have influence on bearing quality and output.Existing electric main shaft is power little (15-20kw) mostly, and efficient is low, and water resistance is poor, the maintenance cost height.If add high-powerly, must increase iron core, armature spindle length increases like this, and corresponding rigidity decline must influence the armature spindle operating accuracy.In certain size, limited the increasing of armature spindle power like this.It adopts annular cooling bath in addition, and radiating effect is good inadequately, and waterproof sealing is good inadequately, can not guarantee that electric main shaft is reliable and stable.
Summary of the invention
The purpose of this utility model is exactly that a kind of rotating speed height, big, the high rigidity of permanent torque rotary speed scope, good heat dissipation effect, electric main shaft that waterproof sealing is good, reliable and stable are provided at above-mentioned weak point.
Solution solution of the present utility model is: a kind of electric main shaft, it comprises the cooling system of armature spindle, axle housing, motor stator, rotor, block bearing, labyrinth type waterproof construction, band water circulating slot, and it is characterized in that: the water circulating slot of described cooling system is to be positioned at the helicla flute that is provided with on the casing inner wall adjacent with stator.
The position that the described armature spindle front end of solution solution of the present utility model is relative with the dust cap of casing end is provided with and pushes away tank.
The described motor stator structure of solution solution of the present utility model is of a size of Φ 130X137.
The utility model is owing to the water circulating slot with cooling system is designed to be positioned at the helicla flute that is provided with on the casing inner wall adjacent with stator, thereby after electric spindle power strengthens, the cooling water of this water circulating slot constantly the heat of main motor in time, promptly take away, both can avoid taking place because of the extra heating of motor makes the phenomenon that efficient reduces, power output reduces, can not increase iron core again, do not increase armature spindle length, avoid rigidity to descend, the situation that simultaneously can avoid the heating of motor and directly reduce the bearing working precision takes place, and guarantees that electric main shaft is reliable and stable.The utility model is owing to be provided with the spiral tank that pushes away at the armature spindle front end position relative with the casing dust cap, thereby can further improve cooling effect.The utility model is owing to be designed and sized to Φ 130X137 with motor stator structure, thereby can make electric maximum speed of spindle reach 12000r/min and permanent torque rotary speed scope is 6000-12000r/min, and the rated power of armature spindle is 25kw.The utlity model has that maximum speed height, big, the high rigidity of permanent torque rotary speed scope, high speed and multistep speed regulation, built-in motor physical dimension are little, good heat dissipation effect, characteristics that waterproof sealing is good, reliable and stable.The utility model is mainly used in the electric main shaft frock of bearing mill processing.
Description of drawings
Fig. 1 structural representation of the present utility model;
Fig. 2 is the partial enlarged drawing that pushes away the tank part among Fig. 1.
The specific embodiment
The utility model will be further described below in conjunction with accompanying drawing:
As shown in Figure 1 and Figure 2.The utility model is made of armature spindle 1, axle housing 2, motor stator 3, rotor 4, block bearing 5, labyrinth type waterproof construction, cooling system.The water circulating slot of cooling system is to be positioned at the helicla flute 8 that is provided with on axle housing 2 inwalls adjacent with stator 3.Cooling water 9 is arranged in the cooling system.Armature spindle 1 front end surface and axle housing 2 dust caps 6 relative positions are provided with and push away tank 7, push away tank 7 and are helicla flute.Motor stator 3 physical dimensions are Φ 130X137, realize that electric maximum speed of spindle reaches 12000r/min, and the rated power of armature spindle is 25kw.The labyrinth type waterproof construction is a prior art, has waterproof effect preferably.
