The utility model has the advantages that: 1. the motor that volume small-power is larger is again had to the advantage reducing motor winding, rotor cage bar, bearing temperature rise, and respond well; 2. rational in infrastructure, simple; 3., owing to can meet the temperature requirement of heavy-duty motor with small size, therefore there is higher economy.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation;
Fig. 2 is support set end view.
Embodiment
The utility model is illustrated below in conjunction with accompanying drawing;
As shown in Figure 1, the utility model comprises horizontal mozzle 1, support set 2, spacer shell 3, water-sealed bearing 4, hole back-up ring 5, interior pipe 6, tank shell 7, semiaxis 1, connecting pin 9, semiaxis 2 10, water inlet 11, delivery port 12, and described semiaxis 1 is connected by connecting pin 9 with semiaxis 2 10; Arrange centre bore 13 in described semiaxis 2 10, arrange horizontal mozzle 1 in described centre bore 13, the two ends of horizontal mozzle 1 are fixed in described centre bore 13 by support set 2, spacer shell 3; Arrange water-sealed bearing 4 in spacer shell 3, one end of interior pipe 6 is fixed on described water-sealed bearing 4, the water inlet 11 in addition on one end joining water box housing 7; Interior pipe 6 is communicated with horizontal mozzle 1; Horizontal mozzle 1 sets out water hole 14 away from one end of interior pipe 6; The end face of support set 2 arranges uniform aperture 21; The cooling water flowed out from described apopore 14 flows into tank shell 7 through support set, interior pipe 6 with centre bore 13 gap, is finally flowed out by the delivery port 12 of tank shell 7; Described hole back-up ring 5 is arranged on water-sealed bearing 4 near water inlet 11 end.
For reaching overall cooling-down effect, and simplify the structure of circulation waterway, the water inlet 11 of described tank shell and delivery port 12 are all communicated with the front end housing of motor, rear end cap cooling system.
For the temperature of Real-Time Monitoring motor internal key position, in motor stator winding, in front end housing, in rear end cap, all temperature element is set.Temperature element can adopt PT100 (platinum resistance thermometer sensor);
As shown in Figure 2, described support set 2 section configuration is that centre has a punching, and surrounding has the structure of multiple aperture, and the quantity of described support set 2 is according to the length variations of axle, and uniform; Horizontal mozzle 1 is supported on axle center by the centre bore of support set 2, and cooling water flows through in the aperture of support set 2 surrounding.
The copper loss that motor stator winding copper loss and rotor cage bar produce respectively accounts for 20% of motor total losses, and the iron loss that stator core, rotor core produce accounts for 40% of motor total losses altogether, and all the other motor are mechanical loss etc.When motor exports rated power, these losses produce a large amount of heats by making motor, use the temperature rise being greatly reduced axle after rotating cooling system by cooling water: axle makes the heat of rotor cage bar be taken away by rotor core on the one hand, rotor temperature rise is reduced greatly, and after rotor surface heat do not diffuse into stator core, directly make stator core, the temperature rise of stator winding greatly reduces, thus improve the useful life of motor; We are when designing high-power motor on the other hand, generally front end housing, rear end cap are designed to water-cooling structure, bearing outside is made to be forced cooling by water like this, coordinate the small fan of motor inner chamber inside end cap water-cooled more simultaneously, the heat of iron core is blowed to end cap, and the temperature rise of motor inner chamber also reduces greatly.And the heat of pipe cannot be taken away in bearing, after increasing now the rotation cooling system of axle, bearing internal external sleeve is cooled directly with water simultaneously, and the temperature rise of bearing reduces greatly, improves the useful life of bearing.Structure of the present utility model, when motor normally works, is jointly carried out water cooling to motor with the forward and backward end cap of original motor and support water cooling system, is made cooling effect better.
In motor stator winding, in front end housing, in rear end cap, all place PT100 (platinum resistance thermometer sensor) as temperature element; Outside front end housing, rear end cap, rear spindle nose (i.e. motor install swivel joint side) motor uses far infrared temperature measurer to measure when doing experiment; Axle water-cooling system is comparatively large on motor each position temperature rise impact, has and reduces motor winding, rotor cage bar, the significant advantage of bearing temperature rise, can meet the requirement of user, adapts to the demand in market.
Interior pipe of the present utility model and tank shell 7 are fixed, and horizontal mozzle is fixed in semiaxis two and also rotates thereupon; And interior pipe is communicated with horizontal mozzle by water-sealed bearing, not only ensure that the reliable of sealing, and structure is simple, in addition, the cooling water in horizontal mozzle rotates with axle, adds centrifugal force, makes flow of cooling water more unobstructed.The outer cross section of support set of the present utility model is regular polygon, if the present embodiment is octagon; Also can adopt regular hexagon, square etc., adopt the benefit of this structure to be convenient to be fixed in the centre bore of semiaxis two, in like manner, the inner hole section of support set be also regular polygon so that fixing horizontal mozzle, prevent the rolling of horizontal mozzle.
In Fig. 1, the direction of arrow is flow of cooling water direction.
