Abstract
Continue cold motor, including electric notor the invention discloses a kind of air；The output end of electric notor is connected with central shaft；Adapter sleeve is arranged with central shaft, free roller clutch is arranged with adapter sleeve, tube-axial fan is arranged with the free roller clutch；It is arranged on central shaft for carrying out spacing back-up ring to tube-axial fan, pad is provided between back-up ring and fan.When electric notor is powered drives the central shaft, fan drives therewith, and when electric notor does not drive the central shaft, the fan still may proceed to rotate certain hour, continues as electric notor and provides cooling air.
Description
Technical field
Continue cold motor the present invention relates to a kind of air, more particularly to a kind of air of paint sprayer continues cold motor.
Background technology
The paint sprayer for using at present is to rotate a central shaft using electric notor to realize the sprinkling to coating, in the middle of the process of sprinkling, the rotary motion of central shaft is converted to reciprocating motion by central shaft sometimes through bent axle or cam or eccentric wheel, the pressure in paint sprayer is increased by a pump again, coating is sprayed and applied with this pressure.When system pressure is increased above maximum stall pressure, electric notor will be automatically switched off.As coating is sprayed, the system pressure in paint sprayer declines, once system pressure is decreased below a specified location, electric notor will restore electricity for resupplying maximum pressure to paint sprayer.
Electric notor can distribute substantial amounts of heat in the case of opening and closing and normal work causes temperature to raise, it is necessary to a cooling device is lowered the temperature to electric notor during use, it is to avoid it exceedes its rated temperature.
Therefore those skilled in the art are devoted to exploitation one kind when constant temperature or electric notor stop driving central shaft, and the air for continuing to provide cooling air continues cold motor.
The content of the invention
In view of the drawbacks described above of prior art, the technical problems to be solved by the invention are to provide one kind when constant temperature or electric notor stop driving central shaft, and the air for continuing to provide cooling air continues cold motor.
To achieve the above object, cold motor, including electric notor are continued the invention provides a kind of air；The output end of electric notor is connected with central shaft；Adapter sleeve is arranged with central shaft, free roller clutch is arranged with adapter sleeve, tube-axial fan is arranged with free roller clutch；It is arranged on central shaft for carrying out spacing back-up ring to tube-axial fan, pad is provided between back-up ring and fan.
In order to extend the service life of adapter sleeve and improve the stability of device, adapter sleeve is made of stainless steel.
The beneficial effects of the invention are as follows：The present invention can continue to provide cooling air when constant temperature or electric notor stop driving central shaft；With simple structure, the low beneficial effect of improvement cost.
Brief description of the drawings
Fig. 1 is the structural representation of the embodiment of the invention.
Fig. 2 is cross section structure diagram of the present invention.
Fig. 3 is the temperature changing curve diagram that electric notor works at different conditions.
Specific embodiment
With reference to the accompanying drawings and examples
The invention will be further described：
As shown in Figure 1-Figure 3, a kind of air continues cold motor, including electric notor 12, the output end of electric notor 12 is connected with central shaft 14, adapter sleeve 28 is arranged with central shaft 14, adapter sleeve 28 is made of stainless steel material, for limiting the moving axially relative of central shaft 14 and free roller clutch 18.The end of central shaft 14 is provided with the groove assembled with adapter sleeve 28, in order to prevent the axial movement of adapter sleeve 28, the nearly motor-end of adapter sleeve 28 abuts groove step, remote motor-end is provided with pad 30 and back-up ring 32 is used to fix, and reach adapter sleeve 28 with this does not have the effect of axial freedom with the circumferential free degree.Free roller clutch 18 is arranged with adapter sleeve 28, tube-axial fan 16 is arranged with free roller clutch 18.
Electric notor 12 is started working in the case of energization and is rotated in the direction of the clock, output end central shaft 14 is driven by the rotation of agreement direction of rotation, the free roller clutch 18 being now connected with central shaft 14 by adapter sleeve 28 is also rotated in the direction of the clock, the fan 16 being set with the outer ring of free roller clutch 18 is started working, rotate in the direction of the clock, lower the temperature to the conveying cooling air of electric notor 12 powered electric motor 12.After the power-off of electric notor 12, the reduction of the rotary speed of electric notor 12, the component coupled together in real time by central shaft 14 is simultaneously rotated speed reduction, inner ring (inner ring for being assembled with central shaft 14) and the central shaft 14 of free roller clutch 18 now rotate together with speed reduction, and outer ring (outer ring assembled with fan 16) continues to be rotated in the direction of the clock with than the faster speed of central shaft 14 with fan 16, continue as electric notor 12 and cooling air is provided, free roller clutch 18 allows (direction of rotation of the central shaft 14) afterflow only in the direction of the clock of fan 16.This structure when electric notor 12 is powered admissible centre axle 14 drive fan 16, once and electric notor 12 power off, then allow fan 16 continue rotate, realize afterflow cool down.
As shown in figure 3, being the temperature change contrast curve in varied situations over time of electric notor 12, transverse axis represents the duration of runs (t), and vertical pivot represents the temperature (T) of electric notor 12.Curve 40 represents the temperature change of the electric notor 12 of configuration fan attachment, and curve 42 represents that air continues the temperature change of cold motor.Electric notor 12 is all the temperature change contrast measured in quick situation about opening and closing.It can be seen that the temperature change that air continues cold motor is smaller, the temperature of electric notor 12 is lower, more advantageous.
Preferred embodiment of the invention described in detail above.It should be appreciated that one of ordinary skill in the art just can make many modifications and variations without creative work with design of the invention.Therefore, all technical staff in the art, all should be in the protection domain being defined in the patent claims under this invention's idea on the basis of existing technology by the available technical scheme of logical analysis, reasoning, or a limited experiment.
