The speed reducer comprises a box body (1) and is characterized in that: end covers (1) are connected at both sides of the box body (1), an output shaft (3) penetrates through the box body, two end parts of the output shaft stretch out of the end covers, the output shaft is connected with a clutch (5) through a spline (4), a locating block (6) is clamped on the clutch, a movable gib (7) is connected with the locating block, a worm gear (8) is connected in the middle part of the output shaft, a worm gear is meshed with an input shaft (9), and two ends of the input shaft stretch out of the box body.
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 green house of vegetables.
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 does not have clutch mechanism, therefore can't arbitrarily carry out power transmission as required, and operability is relatively poor.
The model utility content
The utility model provides a kind of speed reducer that is used for green house of vegetables, and it mainly is to solve the existing in prior technology speed reducer not have clutch mechanism, therefore can't arbitrarily carry out power transmission, the technical problem of the relatively poor grade of operability as required.
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 green house of vegetables of the utility model comprises casing, and described casing both sides all are connected with end cap; Cross-under has output shaft in the casing, and all stretch out outside the end cap end, two ends of output shaft, and output shaft is connected with clutch through key; Be connected with positioning block on the clutch, pin is drawn in positioning block connection activity, and the output shaft middle part is connected with worm gear; Worm gear is engaged with input shaft, and stretch out outside the casing at the input shaft two ends.Behind the input shaft input power, promptly begin to rotate with the worm gear of its engagement, output shaft is given in last transmission, and output shaft can be connected with miscellaneous equipment.Draw pin through spurring activity, can drive the clutch move left and right, can make output shaft select engagement like this or leave worm gear, outputting power so at any time, operability is stronger.
As preferably, be provided with lips encapsulate outside framework oil seal between described end cap outer end and the output shaft.Lips encapsulate outside framework oil seal 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.
As preferably, be provided with clutch shaft bearing between described end cap the inner and the output shaft.Like this can be so that output shaft is more smooth and easy rotatably.
As preferably, be provided with second bearing between described input shaft two ends and the casing.Like this can be so that input shaft is more smooth and easy rotatably.
Therefore, the inside of the loved retarder of the utility model adds clutch, draws pin can control when outputting power of output shaft through activity, and preferable operability can adapt to the needs of green house of vegetables, 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: pin 7, worm gear 8, input shaft 9, lips encapsulate outside framework oil seal 10, clutch shaft bearing 11, second bearing 12 are drawn in casing 1, end cap 2, output shaft 3, key 4, clutch 5, positioning block 6, activity.
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 green house of vegetables of this example; Like Fig. 1, Fig. 2; A casing 1 is arranged, and the both sides of casing all are connected with end cap 2, and cross-under has output shaft 3 in the casing; Be provided with lips encapsulate outside framework oil seal 10 between end cap outer end and the output shaft 3, be provided with clutch shaft bearing 11 between end cap the inner and the output shaft.The end, two ends of output shaft is all stretched out outside the end cap; Output shaft is connected with clutch 5 through key 4, is connected with positioning block 6 on the clutch, and pin 7 is drawn in positioning block connection activity; The output shaft middle part is connected with worm gear 8; Worm gear is engaged with input shaft 9, and stretch out outside the casing at the input shaft two ends, is provided with second bearing 12 between input shaft 9 two ends and the casing.
During use, input shaft 9 places input power, input shaft drive worm gear 8 rotations; Draw pin 7 controlled clutches 5 through activity; Make output shaft 3 and worm gear mesh, output shaft promptly can transmit power to connected miscellaneous equipment like this, cuts off transmission like need; Can reversible control clutch 5, make output shaft 3 throw off and get final product with worm gear.
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.
