Abstract
The utility model relates to a generator dividing slip ring chamber ventilation structure, which comprises a slip ring chamber. An air inlet corresponding to an air outlet of a motor cooler is arranged above the slip ring chamber, a first air guide plate and a second air guide plate are obliquely arranged at the position of the air outlet, the air inlet is divided into three passages including a left passage, a middle passage and a right passage by the first air guide plate and the second air guide plate, and the left passage, the middle passage and the right passage face the connected end face of the slip ring chamber and an end cap, the front of the slip ring chamber and the rear of the slip ring chamber respectively. By the aid of dividing structures of the air guide plates, the generator dividing slip ring chamber ventilation structure is not required to be provided with an extra radiating window on a slip ring but simultaneously satisfies the cooling requirements for bearings, the end caps, carbon brushes and the slip rings, and improves the IP (ingress protection) of a motor, internal cooling of the slip ring chamber is more even and the service lives of components such as the carbon brushes are prolonged. The structure is simpler and more compact because of omission of a fan hood, and running reliability of a motor is effectively improved.
Description
Technical field
The utility model relates to the structure of generator slip ring chamber, especially relate to a kind of can cooling bearing, the shunting of end cap, carbon brush and slip ring, good seal, simple in structure and compact, improve the generator shunting slip ring chamber ventilated structure of running reliability of motor.
Background technology
In generator, it is indoor that bearings machine shaft, device have the machine shaft of slip ring to be positioned at slip ring, because machine shaft is in operation, bearing, end cap, carbon brush and slip ring can produce heat, needs to introduce cooling blast and take away the heat that is produced.Prior art is to open extra heat radiation window on the fan guard of slip ring chamber, introduces cooling blast by cooler and fan, has increased ventilation though do the slip ring chamber like this, has also reduced the IP degree of protection, makes component life shortenings such as carbon brush.
The utility model content
The purpose of this utility model is to overcome the problems referred to above and deficiency, provides that a kind of cost is low, good seal, simple in structure and compact, the generator shunting slip ring chamber ventilated structure that improves running reliability of motor.
The technical solution of the utility model is as follows:
A kind of generator shunting slip ring chamber ventilated structure, comprise the slip ring chamber, top, slip ring chamber offers and the corresponding air intake vent of the air outlet of cooler of electric motor, described air intake vent place is provided with first wind deflector and second wind deflector, and described first wind deflector and second wind deflector are separated into three passages in left, center, right with air intake vent.
Its further technical scheme is: the end face that three passages in described left, center, right are connected with end cap towards the slip ring chamber respectively, front portion, slip ring chamber and rear portion, slip ring chamber.
And its further technical scheme is: described first wind deflector and second wind deflector tilt to place the air intake vent place.
Useful technique effect of the present utility model is:
The utility model uses the shunting structure of wind deflector, not be used on the fan guard of slip ring chamber and opens extra heat radiation window, has satisfied the cooling requirement to bearing, end cap, carbon brush and slip ring simultaneously, and has improved the IP degree of protection of motor.Make that also the cooling of slip ring chamber interior is more even, the useful life of improving parts such as carbon brush.Because of it has saved fan guard, make structure more simple and compact, can improve the operational reliability of motor effectively.

Embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is described further.
As shown in Figure 1, the overall structure of motor is: bearing 2 is sleeved on the motor shaft 1,2 liang of end devices of bearing have internal bearing cover and bearing end cover, the peripheral equipment of bearing 2 is in the end cap 3 that links to each other with motor cabinet, end cap 3 is connected with slip ring chamber 7 usefulness bolts, slip ring chamber 7 upper end air intake vents are connected with cooler 5 usefulness bolts, slip-ring device in the slip ring chamber 7 is on motor shaft 1, brush holder support 9 is fixedly connected on the slip ring chamber 7, the carbon brush 8 that is arranged on the brush holder support 9 is relative with the slip ring position, the quantity of slip ring is a plurality of, and the number of same carbon brush 8 also is a plurality of, and its quantity equates with the quantity of slip ring.
As shown in Figure 1 and Figure 2, slip ring chamber ventilated structure of the present utility model comprises slip ring chamber 7, and 7 tops, slip ring chamber offer and the corresponding air intake vent 10 of the air outlet of cooler 5.Air intake vent 10 places are provided with first wind deflector 4 and second wind deflector, 6, the first wind deflectors 4 and second wind deflector 6 and tilt to place air intake vent 10 places.First wind deflector and 4 second wind deflectors 6 are separated into three passages in left, center, right with air intake vent 10.The end face that three passages in left, center, right are connected with end cap 3 towards slip ring chamber 7 respectively, 7 front portions, slip ring chamber and 7 rear portions, slip ring chamber.
As shown in Figure 3, be incorporated into the cooling blast of slip ring chamber 7 from cooler 5, two bafflers by slip ring chamber 7 upper end air intake vents 10 are divided into three strands of air-flows: one air-flow is introduced in end cooling bearing and the end cap that the slip ring chamber is connected with end cap, one middle air-flow and one air-flow on the right are incorporated into the front and rear of slip ring chamber respectively, are used for cooling off carbon brush and slip ring.Adopt the shunting structure of this baffler, not be used on the fan guard of slip ring chamber and open extra heat radiation window, satisfied cooling requirement simultaneously to bearing, end cap, carbon brush and slip ring, the IP degree of protection that has improved motor makes that also the cooling of slip ring chamber interior is more even, the useful life of improving parts such as carbon brush.And the slip ring chamber of this form because of it has saved fan guard, makes structure more simple and compact, can improve the operational reliability of motor effectively.
Above-described only is preferred implementation of the present utility model, and the utility model is not limited to above embodiment.Be appreciated that other improvement and variation that those skilled in the art directly derive or associate under the prerequisite that does not break away from spirit of the present utility model and design, all should think to be included within the protection range of the present utility model.
