Abstract
The utility model discloses a cylinder bearing housing air inlet structure of circumference stringing, including setting up fan and the inlet wind cover at the non - shaft extension of motor end, its characterized in that: the inlet wind cover terminal surface seals and its inner wall is provided with the acoustical coating layer, inlet wind cover's side wall cloth is equipped with the air inlet window. Laying the lateral wall at inlet wind cover with the air inlet window, having changed the air current route, confined inlet wind cover terminal surface plays the effect that effectively blocks to the noise of motor inside, simultaneously, combines together with confined inlet wind cover terminal surface through set up the acoustical coating layer at inlet wind cover, has greatly reduced the motor noise pollution, simple structure, simple installation, with low costs.
Description
Technical field
The utility model belongs to noise of motor control technology field, is specifically related to a kind of cartridge type bearing housing air inlet structure of circumference stringing.
Background technology
Along with the continuous lifting that industry environmental protection requires, noise examination becomes an important indicator of motor performance gradually. Common air cooling motor outer ventilation line structure at present, the air intake cover that the main upper fan by machine shaft and end face offer air inlet forms, when motor operation, fan rotation, extraneous air is sucked to also side direction from air inlet and throw away formation blast, air-flow enters the cooling tube on electric machine stand and discharges from the other end, realizes the air cooling cooling to motor. Due to fan rotation compressing air-flow, can produce ventilation noise, simultaneously, air inlet place easily forms eddy current, produces eddy current crack, and noise is under the effect of air intake cover, spread out of from the air inlet of air intake cover end face on the one hand, spread out of on the other hand the particularly inlet side of motor through cooling tube outlet air end, because fan is just to air inlet, fan noise can directly spread out of from air inlet, and motor internal rotor also can produce noise, form multiple noise stack, cause noise pollution serious.
Utility model content
The purpose of this utility model is for above-mentioned the deficiencies in the prior art, and a kind of simple in structure, simple installation, low noise, the cartridge type bearing housing air inlet structure of circumference stringing are cheaply provided.
For realizing the technical scheme that the purpose of this utility model adopts be: this air inlet structure comprises the fan and the air intake cover that are arranged on motor non-shaft stretching end, it is characterized in that: described air intake cover end face sealing and its inwall are provided with quieter material layer, and the sidewall of described air intake cover is laid with air intake window.
In described air intake cover, be provided with umbrella hood, this umbrella hood top is provided with suction nozzle, and the inside sidewalls sealing of umbrella hood periphery and described air intake cover is connected.
The junction of the corner of described umbrella hood and umbrella hood and suction nozzle is fillet or chamfering structure.
Described suction nozzle and the flabellum of described fan intersect dislocation certain distance.
Described umbrella hood and suction nozzle are provided with quieter material layer.
The utility model is by being laid in air intake window the sidewall of air intake cover, change air flow path, the air intake cover end face of sealing plays effective barrier effect to the noise of motor internal, simultaneously, by being set at air intake cover, quieter material layer combines with the air intake cover end face of sealing, greatly reduced noise of motor pollution, simple in structure, simple installation, cost are low. Further by umbrella hood is set in air intake cover, on the one hand, umbrella hood contributes to improve blast, improve cooling effectiveness, on the other hand, umbrella hood forms guiding function to air-flow, makes cooling-air be distributed in equably the air intake of cooling tube, improve the cooling effectiveness of each cooling tube, and then greatly improved on the whole the integral heat sink efficiency of cooling mechanism; Meanwhile, umbrella hood, in guiding air-flow, can effectively reduce the noise producing in air current flow process, and the noise of air-flow and motor internal generation is had to certain barrier effect, and the noise pollution situation of outside motor is further reduced. Suction nozzle and flabellum intersect dislocation certain distance, can effectively improve wind path whole efficiency, avoid leaking out, step-down situation occurs.
Brief description of the drawings
Below in conjunction with accompanying drawing, the utility model is described further:
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
Referring to Fig. 1, the cartridge type bearing housing air inlet structure of circumference stringing of the present utility model, comprise the fan 8 and the air intake cover 2 that are arranged on motor non-shaft stretching end, all sides of electric machine stand are laid with some axial cooling tubes 1, and described air intake cover 2 is cylinder-like structure, its one end is connected with the cooling tube 1 of electric machine stand week side, the other end is the end cap of sealing, and end cap inwall is provided with quieter material layer 4, simultaneously, the sidewall of air intake cover 2 is laid with air intake window 5, and air intake window 5 has filter.
Be further used as preferred version, in described air intake cover 2, be provided with umbrella hood 3, these umbrella hood 3 tops are provided with suction nozzle 6, the inside sidewalls welded seal of umbrella hood 3 peripheries and described air intake cover 2 is connected, and the corner of described umbrella hood 3 and umbrella hood 3 are fillet or chamfering structure with the junction 7 of suction nozzle 6. Described suction nozzle 6 and the flabellum of described fan 8 intersect dislocation certain distance lap but do not contact. On described umbrella hood 3 and suction nozzle 6, be provided with quieter material layer.
When motor operation, fan 8 rotates, air-flow enters air intake cover 2 from air intake window 5, arrive fan 8 places through suction nozzle 6, under fan 8 centrifugal actions, be thrown out of, the even spreading of guide functions by umbrella hood 3 is in the air intake of cooling tube 1, and brings out wind along cooling tube 1 to shaft extension, and its circulation track as shown by the arrows in Figure 1. The utility model passes through at air intake cover 2 sidewall air intakes, wind guides by umbrella hood 3, changed air flow path, wind path lengthens, and fan noise weakens, simultaneously, fillet or chamfering structure are more conducive to airflow, and reduce wind the moon, the generation of noise decrease, quieter material layer during to noise row further absorb, thereby greatly reduced noise of motor pollution.
The technical solution of the utility model is not restricted in the scope of embodiment described in the utility model, and the utility model not technology contents of detailed description is known technology.
