Abstract
The utility model relates to a speed reducer, especially a speed reducer for an incubation device, which mainly solves the technical problem of the prior technology that: the conventional speed reducer can not perform the eccentric control, thus the conventional speed reducer is not suitable for the incubation device. The speed reducer comprises a box body (1), characterized in that: a first worm is through the bottom of the box body (1), one end of the first worm extends outside the box body and is connected with a pulley (3), the first worm is engaged with a small worm gear (4), a second worm (6) is fixed on the small worm gear by a flat key (5) and engaged with a large worm gear (7), a worm gear axle (8) is arranged in the middle of the large worm gear and an eccentric axle (9) is connected with the edge of the large worm gear.
Description
Technical field
The utility model relates to a kind of speed reducer, especially relates to a kind of speed reducer that is used for incubation equipment.
Background technique
At present; Miniature gear speed reducer, the worm-gear speed reducer of being used widely; Receive volume restrictions, its speed ratio is less than normal, and its transmission direction is generally parallel input output and can not satisfies some existing large speed ratios mini-plant that has vertical transmission direction to require again that slows down and install and use.Chinese patent discloses a kind of double worm and gear speed reducer structure (notice of authorization number: CN 201250880Y); It comprises worm type of reduction gearing; Be provided with two worm type of reduction gearings; Worm screw on two worm type of reduction gearings links together through the coupling of axial rotation adjustable angle, realizes synchronization; Have at least one worm screw two ends all to stretch out in himself reducer shell in two worm type of reduction gearings, with a end that coupling is not installed on this worm screw input shaft as this reducing gear; Output shaft on each worm type of reduction gearing is connected with a small gear respectively; Small gear simultaneously and the gearwheel engagement driving, and with the transmission shaft at gearwheel place output shaft as this reducing gear; The two ends of the worm screw of two worm type of reduction gearings all stretch out in the housing of retarder itself separately; Two worm type of reduction gearings and connected small gear respectively; Have identical specification respectively, the coupling of employed axial rotation adjustable angle is made up of two half-couplings, and some screws evenly distribute on one of them half-coupling; Corresponding described screw is provided with the slotted hole of some arcs on another half-coupling, is fastenedly connected through screw between two half-couplings.But this speed reducer can't carry out eccentricity control, therefore can't be applicable to incubation equipment.
The model utility content
The utility model provides a kind of speed reducer that is used for incubation equipment, and it mainly is to solve the existing in prior technology speed reducer can't carry out eccentricity control, therefore can't be applicable to the technical problem of incubation equipment etc.
The above-mentioned technical problem of the utility model mainly is able to solve through following technical proposals:
A kind of speed reducer that is used for incubation equipment of the utility model comprises casing, and described bottom half cross-under has first worm screw; First worm screw, one end stretches out outside the casing and is connected with belt pulley; First worm meshing has small gear, and small gear is fixed with second worm screw through flat key, and second worm meshing has big worm gear; Be provided with worm-wheel shaft in the middle of the big worm gear, big worm gear edge is connected with eccentric shaft.Behind first worm screw input power, promptly begin to rotate with the small gear of its engagement, drive big worm gear rotation through second worm screw then, the eccentric shaft on the big worm gear promptly can eccentric motion, makes it can be applicable to incubation equipment.The bottom surface of casing can be provided with zinc-plated breather.Stretch out outside the casing the first worm screw end, can be used for connecting belt pulley, thereby form the power input source.
As preferably, be provided with first deep groove ball bearing between described first worm screw and the casing.Such first worm screw is more smooth and easy rotatably.
As preferably, be provided with second deep groove ball bearing between described second worm screw two ends and the casing.Such second worm screw is more smooth and easy rotatably.
As preferably, be provided with the 3rd deep groove ball bearing between described worm-wheel shaft and the casing.Worm-wheel shaft is more smooth and easy rotatably like this.
As preferably, all be connected with the oil sealing end cap on the casing at described worm-wheel shaft one end, the second worm screw two ends.Oil sealing can prevent that the fluid in the casing from leaking outside, and also can prevent that the outside dust and other impurities of speed reducer from invading speed reducer inside simultaneously.
Therefore, the utility model is utilized on the big worm gear eccentric shaft is set, and utilizes belt pulley as the power input source, makes speed reducer can be applied to incubation equipment like this, and is simple and reasonable for structure.
Description of drawings
Accompanying drawing 1 is a kind of structural representation of the utility model;
Accompanying drawing 2 is side structure schematic representation of Fig. 1.
Component, position and numbering among the figure: casing 1, first worm screw 2, belt pulley 3, small gear 4, flat key 5, second worm screw 6, big worm gear 7, worm-wheel shaft 8, eccentric shaft 9, first deep groove ball bearing 10, second deep groove ball bearing 11, the 3rd deep groove ball bearing 12, oil sealing end cap 13.
Embodiment
Pass through embodiment below, and combine accompanying drawing, do further bright specifically the technological scheme of the utility model.
Embodiment: a kind of speed reducer that is used for incubation equipment of this example; Like Fig. 1, Fig. 2, a casing 1 is arranged, the bottom half cross-under has first worm screw 2; First worm screw, one end stretches out outside the casing and is connected with and is provided with first deep groove ball bearing 10 between belt pulley 3, the first worm screws and the casing.First worm meshing has small gear 4, and small gear is fixed with between second worm screw, 6, the second worm screw two ends and the casing through flat key 5 and is provided with second deep groove ball bearing 11.Second worm meshing has big worm gear 7, is provided with worm-wheel shaft 8 in the middle of the big worm gear, is provided with the 3rd deep groove ball bearing 12 between worm-wheel shaft and the casing 1.Big worm gear edge is connected with eccentric shaft 9.All be connected with oil sealing end cap 13 on the casing at worm-wheel shaft one end, second worm screw, 6 two ends.
During use, belt pulley 3 places input power, first worm screw 2 drives small gear 4 rotations; Also begin rotation with second worm screw 6 of small gear 4 engagements; Thereby drive big worm gear 7 rotations, the eccentric shaft 9 on the big worm gear promptly begins to carry out the off-centre rotation, and eccentric shaft promptly can be given incubation equipment with transmission of power.
The above is merely the specific embodiment of the utility model; But the structure characteristic of the utility model is not limited thereto; Any those skilled in the art is in the field of the utility model, and variation of being done or modification all are encompassed among the claim of the utility model.
