Abstract
A manual film rolling device small tooth number difference planetary deceleration device relates to the technical field of the greenhouse curtain manual folding and unfolding for the facility agriculture greenhouse equipment, wherein, one end of the planetary gear shaft is integrated with the input shaft; the planetary gear is rotatably sleeved on the planetary gear shaft; the other end of the planetary gear shaft is fixed with the shaft end connecting sheet; the planetary gear is simultaneously engaged with the fixed ring gear and the output inner gear shaft. The ring gear is fixed; the output inner gear shaft is rotatable; and the tooth number difference thereof is 1-8. The utility model is used for folding/unfolding and locking for the greenhouse curtain.
Description
Technical field
The utility model relates to a kind of device of manual folding and unfolding greenhouse curtain of industrialized agriculture greenhouse facilities, particularly a kind of manual film winder fewer differential teeth planetary speed reducer.
Background technique
In the industrialized agriculture technology, the proportion of greenhouse culture technique in agricultural technology improves day by day.Greenhouse culture technique proposes different environmental requirements for the needed illumination intensity of different cultivated plants, temperature and ventilation condition, therefore, the needs that corresponding can regulate curtain device guarantees the plant growing growth conditions all are set in chamber facility, by to the opening and rolling of film or other materials curtain, for the institute cultivated plant provides optimum growing environment in the greenhouse.In greenhouse can regulate curtain device, open and the rolling action power of film or curtain generally provide by electronic or manual film winder.Adopt electronic film winder for the curtain device of large greenhouse, and for small-sized greenhouse and since curtain open and rolling action resistance relative less, can adopt manual film winder to realize adjusting action to curtain.In the manual film winder of prior art, generally be to adopt mechanical reduction gear that the rotating speed deceleration of manpower input mechanism is the rotating speed of output mechanism, so that the operator can enough smaller power shake input mechanism, realize opening or the rolling action to heavy curtain.Because plants cultivating condition requirement, heavy curtain is regulated and take-up gear institute stop place needs to regulate often, regulate and take-up gear when resting on a certain position when heavy curtain, its gravity can be delivered to manual film winder by fly rope and make its reversing, makes heavy curtain change the stop place of setting.For heavy curtain being regulated and take-up gear can be stable rests on the needed position, generally on manual film winder, self-locking mechanism is set and prevents to reverse.How to reduce the resistance that self-locking mechanism brings, manual film winder is gone slick, laborsaving, suitable manpower operation's characteristics can be batched operation at any time, and manual film winder is stablized remained on any stop position, be the technical issues that need to address.The manual film winder of prior art generally adopts gear train to slow down, and uses ratchet ratch mechanism, brake disc braking plate mechanism, torsion spring mechanism to realize self-locking, causes mechanism element many, complex structure, and weight is big, and volume is big, easily the technological deficiency that lost efficacy.
The model utility content
In order to solve the technological deficiency that prior art exists, the purpose of this utility model is to provide a kind of manual its volume of film winder fewer differential teeth planetary speed reducer little, and speed ratio is big, low cost of manufacture, and locked position is stable, can realize the output bidirectional self-locking.
To achieve these goals, the technical solution of the utility model is:
A kind of manual film winder fewer differential teeth planetary speed reducer, wherein: planet wheel shaft one end and input shaft connect as one, planet wheel is rotating to be enclosed within on the planet wheel shaft, the planet wheel shaft the other end and axle head connecting sheet are fixed, ring gear and output internal tooth axle mesh planet wheel simultaneously with fixedly, fixedly ring gear is fixed, and output internal tooth axle is rotatable, and the two number of teeth difference is the 1-8 tooth.
Hole back-up ring A is fixed on fixedly and stops a side of exporting the internal tooth axle in the ring gear hole.
Hole back-up ring B is fixed on a side that stops input shaft in the fixing ring gear hole.
Planet wheel and planet wheel shaft are 2 or 3 groups.
Owing to after adopting such scheme, in use, be input shaft with the planetary carrier, two internal gears are formed few tooth difference and one group of planet wheel engagement, utilize that an internal gear is fixed, another internal gear output, planetary carrier can forward and reversely rotate, and output shaft can not be to any direction rotation.The utility model has been realized the output bidirectional self-locking, and self-locking is reliable, and is simple in structure, and volume is little, and weight is little, reduced production and user cost.
Description of drawings
Fig. 1 is a manual film winder fewer differential teeth planetary speed reducer sectional view of the present utility model.
Label in the accompanying drawing:
1. output internal tooth axle, 2. hole back-up ring A, 3. axle head connecting sheet, 4. planet wheel, 5. planet wheel shaft, 6. input shaft, 7 hole back-up ring B., 8. fixing ring gear.
Embodiment
Be further described below in conjunction with the embodiment of Figure of description the manual film winder fewer differential teeth planetary of the utility model speed reducer.
The manual film winder fewer differential teeth planetary of the utility model as shown in Figure 1 speed reducer, wherein: planet wheel shaft 5 one ends and input shaft 6 connect as one, planet wheel 4 rotating being enclosed within on the planet wheel shaft 5, planet wheel shaft 5 the other ends and axle head connecting sheet 3 are fixing, ring gear 8 and output internal tooth axle 1 mesh planet wheel 4 simultaneously with fixedly, fixedly ring gear 8 is fixing, and output internal tooth axle 1 is rotatable, and the two number of teeth difference is the 1-8 tooth.On input shaft 6, apply a running torque, moment will pass to planet wheel 4 by forming planetary carrier by planet wheel shaft 5 and input shaft 6, planet wheel 4 and output internal tooth axle 1,8 engagements of fixing tooth wheel rim are realized the rotation of output internal tooth axle 1, thus output torque.On the contrary, if apply a running torque on output internal tooth axle 1, because the effect of the few tooth difference of two internal gears, output internal tooth axle 1 can not rotate, and realizes the output bidirectional self-locking.Hole back-up ring A2 is fixed on fixedly and stops a side of exporting internal tooth axle 1 in ring gear 8 holes, hole back-up ring B7 is fixed on a side that stops input shaft 6 in fixing ring gear 8 holes, fixedly ring gear 8, output internal tooth axle 1, input shaft 6 are constrained to one, constitute complete mechanism.Planet wheel 4 and planet wheel shaft 5 can be 2 or 3 groups, and be stressed even when making operation like this.
Realized the output bidirectional self-locking, the reliable using effect of self-locking.It can use on the greenhouse film rolling device, also can use other need slow down and the machinery of two-way locking on.
