It is adaptable to need reciprocating sliding straight line (or the certain angle of reciprocating rotary in the every field product such as medical care, office, industry, family
Degree) in the place moved it can also be used to need to rise, the place of the tight working substance that declines or rise in value, typically can achieve at a distance
Concentrate or automatically control.Main usess such as Electric sofa, electronic exhibition booth elevating lever, electric industrial jacking system, camera frame, projection
Machine, wedding celebration system, Electronic Stryker frame, electric care bed etc..Electric pushrod by motor, reduction gearing, screw rod, nut, lead
Set, push rod, slide, spring, shell and turbine, fine motion controlling switch etc. form.
At present, because all of product adopts motor to fixedly mount, for guaranteed efficiency, all of drive deceleration mechanism is equal
High-precision fixed installation is needed to ensure concentricity, so that decelerator is also required to high-precision housing to ensure in operating
Concentricity.Shortcoming one is that space is occupied greatly, firmly toward causing the stroke of whole push rod to be restricted, now often in order to reach design institute
Movement travel is needed to have to for electric machine external or to lose effective travel outside whole push rod linear movement direction；Shortcoming two is ratio
Costly, the complexity of reducing gear causes cost to remain high.
Of the present utility model due to employing floating structure, whole drive and centrad that retarder parts need not be tight is protected
Hold structure, need not any fixing housing.Whole mechanism can keep automatic centrad adaptation adjustment, this design in operation process
Core solved with more easy structure driver part and pushing mechanism be effectively controlled due to floating fixed structure
Concentricity, can play the driving force of motor to greatest extent, and the driver part of high rigidity decreases the efficiency fall in transmission
Low；The vibrations that motor rotation brings it have been effectively isolated, Z-direction fixation is all made up of elastomeric element, can have in the running simultaneously
Elimination leading screw linearity in effect ground is not good and the eccentric caused motor of external structure shakes and unbalance loading.
Utility model content
The purpose of this utility model is to provide one kind can effectively eliminate that leading screw linearity is not good and external structure
Motor vibrations caused by bias and the no housing floating motor reducer structure of unbalance loading.
The technical solution of the utility model is：One kind no housing floating motor reducer structure, it includes the fixing machine that floats
Structure, driver part and pushing mechanism, wherein said floating fixed mechanism includes damping device, elastic supporting member for supporting optical member, elastomeric element
And fixture, described damping device, elastic supporting member for supporting optical member, elastomeric element and fixture are arranged at described driver part and push away
Between motivation structure.
Further, described damping device is damping washer, and described elastomeric element is stage clip, and described fixture is screw.
Further, described driver part include planetary reduction gear external toothing, planetary gear, planet carrier, motor and
Sun gear.
Further, described pushing mechanism includes leading screw, bearing and the support of bearing.
Further, described damping washer is arranged under the planet carrier that motor is connected, described elastic support
It is arranged under described planetary reduction gear external toothing, described stage clip is arranged on the side of described motor, and described screw
It is fixed on the described support of bearing through described stage clip.
In sum, the beneficial effects of the utility model are：1) effectively eliminate leading screw linearity in the running not
The eccentric caused motor vibrations of good and external structure and unbalance loading；2) structure space in linear drives direction is greatly reduced,
Improve effective impulse stroke of push rod.Want to compare with equal motor and Design of Speed Reducer scheme, this technology has saved decelerator
Frame structure is in the structure space in linear drives direction, thus improve the effective impulse stroke in equivalent constructions.3) decrease
Mechanism complexity, reduces manufacture difficulty and cost.Because reducing gear no longer has fixing housing, assembling complexity drops significantly
Low, manufacture difficulty is greatly reduced, decrease manufacturing process, number of components and component processing required precision, and direct saving becomes
This.
This utility model is described in more detail below by embodiment.
Brief description
Fig. 1 is the structural representation of no housing floating motor reducer structure of the present utility model；
Specific embodiment
In the way of embodiment combines accompanying drawing 1, this utility model is further described below.
As shown in figure 1, it illustrates the concrete structure of no housing floating motor reducer structure of the present utility model, this
New no housing floating motor reducer structure includes floating fixed mechanism, driver part and pushing mechanism, wherein floats
Fixed mechanism includes damping device, elastic supporting member for supporting optical member, elastomeric element and fixture, damping device, elastic supporting member for supporting optical member, elastic
Part and fixture are arranged between driver part and pushing mechanism.
Wherein, described damping device is damping washer 6, and damping washer 6, elastic support 13 and stage clip 10 constitute stepping
The floating fixed mechanism of motor；By planetary reduction gear external toothing 4, planetary gear 5, planet carrier 7, motor 8 and sun gear 11
Constitute driver part, leading screw 1 constitutes pushing mechanism with bearing 2 and the support of bearing 12.As shown in figure 1, damping washer 6,
