Abstract
The utility model relates to a damping device of a motor for an infant incubator, which comprises a motor arranged in a case and fan blades, wherein an output shaft of the motor is connected with the fan blades outside the case after penetrating the side wall of the case; the damping device is characterized in that a motor fixing part is also arranged in the case, and the motor is arranged on the motor fixing part; and a transitional part for positioning the motor fixing part is arranged on the inner side wall of the case, and a gap is formed between the transitional part and the motor fixing part at intervals. Compared with the prior art, since the damping device is arranged at the end part of the motor, the vibration and the noise during the working process of the motor are effectively reduced, and the damping device is more favorable for nursing babies.
Description
Technical field
The utility model relates to a kind of infant incubator, specifically refers to the damping device of a kind of infant incubator with motor.
Background technology
Infant incubator comprises cabinet that is provided with various functions in it and the thermostatic chamber that is arranged on the cabinet.Need to keep the environmental key-element of suitable infant physical growths such as certain temperature, humidity and oxygen concentration in the thermostatic chamber, adopt the motor-driven fan blade to rotate usually and realize the damp and hot circulation that thermostatic chamber is interior.
Traditional motor fixed form is to be directly installed on the chassis shell body wall, this structure can produce noise and vibrations inevitably when machine operation, can make the noise in the incubator increase, can produce harmful effect, cause the physiological discomfort of infant the weak or sufferer baby who places in it.
Noise and vibrations when adopting the method that increases the motor accuracy of manufacture to reduce the motor rotation at present in the world, but the high accuracy of manufacture also can increase production cost simultaneously greatly except meeting increases technical difficulty and manufacture difficulty.
Summary of the invention
Technical problem to be solved in the utility model is that the present situation at prior art provides a kind of motor shock-absorbing device for infant incubator that machining accuracy can effectively reduce machine operation noise and vibrations that do not need to go especially to improve.
The utility model solves the problems of the technologies described above the technical scheme that is adopted: this motor shock-absorbing device for infant incubator comprises motor and the fan blade that is arranged in the cabinet, the sidewall that the output shaft of described motor passes cabinet is connected with cabinet fan blade outward, it is characterized in that also being provided with in the described cabinet motor fixture, described motor is arranged on this motor fixture; The madial wall of described cabinet is provided with the transition piece of the described motor fixture in location, and between this transition piece and the described motor fixture space is arranged at interval.
Because at interval the space is arranged between motor fixture and the transition piece, vibrations between the two can not transmitted, only can successively decrease.Therefore the utility model does not need to improve vibrations and the noise that is produced when the accuracy of manufacture promptly can reduce motor rotation greatly especially, more helps the baby and cultivates.
Above-mentioned transition piece can be the connection that is embedded of hole, post with being connected of cabinet madial wall, or the like; Can interconnect by being embedded of hole, post between motor fixture and the motor, or the like.
Preferably, install for convenience, simplify the processing of each parts, described transition piece can be by screw on the sidewall of described cabinet; Described transition piece is provided with the countersunk head screw, screws in described motor fixture and links together thereby sunk screw passes this countersunk head screw.Because the vibrations meeting that is produced during machine operation is transmitted on the transition piece by motor fixture, screw, therefore this programme is provided with screw pad spare and countersunk head pad spare respectively in the countersunk head screw, countersunk head pad spare and screw pad spare can produce secondary damping and noise abatement, effectively avoided the motor vibrations to contact with the rigid of cabinet wall, the vibrations and the noise that are transmitted to like this in the constant heat cabinet for infant are just very little.After tested, the damping device that this programme provided can directly reduce more than the constant temperature room noise 5dB; Countersunk head pad spare and screw pad spare branch are arranged in addition, can either make things convenient for the processing of part, effectively reduce the frictionally damage between screw and the pad part again, prolong physical life; Successively decrease by secondary simultaneously and improved noise reduction greatly
Described countersunk head pad spare and screw pad spare can adopt with respect to motor fixture and the soft silica type material of transition piece and prepare, with the design effect of more outstanding such scheme.
Preferably, can also be provided with the metal positioning sleeve between described sunk screw and the screw pad spare.This scheme can well be supported screw pad spare under the prerequisite that does not influence damping and noise reduction effect, and makes motor fixture more firm in the location of transition piece.
Compared with prior art, the utility model effectively reduces vibrations and noise that machine operation produces by on the end of motor damping device being set, and more helps baby's cultivation.
Description of drawings
Fig. 1 is the sectional structure schematic diagram of the utility model embodiment.
Fig. 2 is the partial enlarged drawing of A part among Fig. 1.
Embodiment
Embodiment describes in further detail the utility model below in conjunction with accompanying drawing.
As depicted in figs. 1 and 2, this motor shock-absorbing device for infant incubator comprises:
Damping device comprises:
Screw pad spare 5 and countersunk head pad spare 4 adopt the preparation of silica gel material, adopt flexible silica gel material preparation, are separately positioned on the screw and the countersunk head position of countersunk head screw 21, also are embedded with the metal positioning sleeve 10 that is used to support screw pad spare in the screw pad spare 5; Metal positioning sleeve 10 can be used as the inserts of screw pad spare 5, directly both is linked together when moulding screw pad spare 5, also can behind forming screw pad spare 5 metal positioning sleeve 10 be inserted in the screw pad spare 5;
Sunk screw 3, passing metal positioning sleeve 10 screws in the motor fixture 6, motor fixture 6 and transition piece 2 are linked together, and countersunk head pad spare 4 is between the countersunk head of the countersunk head of sunk screw 3 and countersunk head screw 21, and screw pad spare 5 is between the nail body of sunk screw 5 and corresponding countersunk head screw
Screw pad spare in the present embodiment and countersunk head pad spare can adopt also that having of other is wear-resisting, the preparation of the flexible rubber material of cushioning effect.
Can earlier the screw pad spare 5 that has been embedded metal positioning sleeve 10 be installed in the transition piece 2 countersunk head screws 21 with countersunk head pad spare 4 during installation, form a transition assembly, with sunk screw 3 this transition assembly is installed on the motor fixture 6 again, constitute the damping device of present embodiment, with screw 9 damping device is installed on the cabinet 1 then, motor 8 and fan blade 7 are installed at last.
Like this, motor is when work, the vibrations of motor self can be transmitted on the flexible screw pad spare 5 and flexible countersunk head pad spare 4 between motor fixture 6 and the transition piece 2, effective buffering of the two through this, divide the two-stage silencing and damping, the transmission of having successively decreased and having shaken between motor and the cabinet wall has avoided motor to contact with the rigid of cabinet, weakened the direct influence of motor, can directly reduce more than the incubator noise 5dB incubator; The countersunk head pad spare that adopted of the countersunk head position of sunk screw 3 not only makes things convenient for the processing of part in addition, and can effectively reduce the friction of sunk screw and screw pad spare, and the vibrations that conduct on the motor fixture are weakened.
