Description
Technical field
The utility model relates to electric pushrod field, particularly relates to a kind of electric pushrod.
Background technology
Electric pushrod is a kind of linear actuating device, utilizes screw nut driven, is the rectilinear motion of push rod by the converting rotary motion of CD-ROM drive motor.Can be used for using as execution machinery, to realize far distance controlled, centralized control or automatically to control in various simple or complicated technological process.Electric pushrod is widely used in electric bed for medical purpose, Electric sofa, electronic exhibition booth elevating lever, electric industrial jacking system etc.In existing electric pushrod running, noise strengthens, and running has vibration.
Summary of the invention
The technical problem that the utility model mainly solves is to provide a kind of electric pushrod, can improve push rod and to operate steadily performance, and reduce vibration, without noise in running, noise is little.
For solving the problems of the technologies described above, the technical scheme that the utility model adopts is: provide a kind of electric pushrod, comprise: drive motors and push rod casing, described push rod box house is provided with worm and worm wheel, and described worm gear is connected on worm screw, described worm gear is connected with leading screw, described drive motors and worm screw are connected, and drive worm screw, and described leading screw is provided with nut, described nut is connected with push rod, one end of described push rod is provided with connector.
In the utility model preferred embodiment, described push rod is provided with support set, described support set is connected with pushing rod sleeve, one end of shown pushing rod sleeve is connected on support set, and the other end is connected on push rod casing, and contacts with nut.
In the utility model preferred embodiment, described nut is also provided with magnet ring.
In the utility model preferred embodiment, between described push rod and support set, be provided with fairlead.
In the utility model preferred embodiment, described worm gear is connected with worm gear set, described drive motors is threephase asynchronous.
The beneficial effects of the utility model are: the utility model electric pushrod, can improve push rod and to operate steadily performance, and reduce vibration, without noise in running, noise is little.
Accompanying drawing explanation
In order to be illustrated more clearly in the technical scheme in the utility model embodiment, below the accompanying drawing used required in describing embodiment is briefly described, apparently, accompanying drawing in the following describes is only embodiments more of the present utility model, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings, wherein:
Fig. 1 is the structural representation of the utility model electric pushrod one preferred embodiment;
Fig. 2 is the left view of electric pushrod shown in Fig. 1;
In accompanying drawing, the mark of each parts is as follows: 1, drive motors, and 2, push rod casing, 3, worm screw, 4, worm gear, 5, leading screw, 6, nut.7, push rod, 8, connector, 9, support set, 10, pushing rod sleeve, 11, magnet ring, 12, fairlead, 13, Cover For A Turbine.
Embodiment
Be clearly and completely described to the technical scheme in the utility model embodiment below, obviously, described embodiment is only a part of embodiment of the present utility model, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making other embodiments all obtained under creative work prerequisite, all belong to the scope of the utility model protection.
Refer to Fig. 1 and Fig. 2, a kind of electric pushrod, comprise: drive motors 1 and push rod casing 2, described push rod casing 2 inside is provided with worm screw 3 and worm gear 4, and described worm gear 4 is connected on worm screw 3, described worm gear 4 is connected with leading screw 5, described drive motors 1 is connected with worm screw 3, and drives worm screw 3, and described leading screw 5 is provided with nut 6, described nut 6 is connected with push rod 7, one end of described push rod 7 is provided with connector 8.
In addition, described push rod 7 is provided with support set 9, described support set 9 is connected with pushing rod sleeve 10, one end of shown pushing rod sleeve 10 is connected on support set 9, and the other end is connected on push rod casing 2, and contacts with nut 6.
In addition, described nut 6 is also provided with magnet ring 11.
In addition, fairlead 12 is provided with between described push rod 7 and support set 9.
In addition, described worm gear 4 is connected with worm gear set 13, described drive motors 1 is threephase asynchronous.
The utility model electric pushrod specific works principle is as follows: after threephase asynchronous passes through the deceleration of worm screw 3 and worm gear 4, drive leading screw 5, nut 6, the rotary motion of threephase asynchronous is converted to rectilinear motion, thus the front and back utilizing rotating to complete push rod 7 are run.Without noise after complete machine energising, noise is tested lower than 65dB at distance 0.5 meter of, and push rod operates steadily without vibration.
Be different from prior art, the utility model electric pushrod, can improve push rod and to operate steadily performance, reduce vibration, without noise in running, noise is little.
The foregoing is only embodiment of the present utility model; not thereby the scope of the claims of the present utility model is limited; every utilize the utility model specification and accompanying drawing content to do equivalent structure or equivalent flow process conversion; or be directly or indirectly used in other relevant technical fields, be all in like manner included in scope of patent protection of the present utility model.
