Abstract
The utility model relates to the improvement of the design of a speed reducer, which is the speed reducer of which worm can be separated and can be used by a straw curtain roller of a greenhouse in countryside. The utility model is characterized in that the utility model is composed of a case body, a worm wheel, a worm, a shaft coupling, an input shaft and a control mechanism; the worm wheel in the case body is engaged with the worm, and the worm wheel can be separated from the worm through the control of the control mechanism, the position of the worm is fixed, and one end is connected together with the input shaft through the shaft coupling. The utility model overcomes the disadvantage that the positions of a driving shaft and a driven shaft of the worm reducer, the mechanical drive and the hand-operated are simultaneously carried out, the electricity is saved, and the convenience is brought to users.
Description
The utility model is the improvement to the retarder design, is the departing retarder of a kind of worm screw.
At present, the axle of domestic worm reducer is that the common design in position is fixed, and input shaft is coaxial with worm screw, the diaxon of worm gear and worm screw is fixed on the casing, both can not break away from, and this structural design does not satisfy the user to be used when the power failure operation, have brought inconvenience in use for the user.
The purpose of this utility model provides a kind of departing retarder of worm screw that is applicable to that rural area warmhouse booth straw screen or mat roller shutter machine uses.
The departing retarder content Description of the utility model worm screw:
The departing retarder of the utility model worm screw, it is characterized in that by: casing, worm gear, worm screw, coupling, input shaft and operating mechanism are formed; Worm gear and worm meshing in the casing can break away from mutually by operating mechanism control, and the position of worm screw is unfixed, and the one end links together by coupling and input shaft; Operating mechanism is fixed on the casing, can be realized by cam, slide block or lever construction.
The departing retarder of the utility model worm screw has overcome the worm reducer driving shaft and the driven axle position can not change and the shortcoming of inconvenience when the power failure operation, make mechanical transmission and manually carry out simultaneously, when transferring straw screen or mat, can finish, promptly save electric energy and brought convenience to the user again without motor operation.
Embodiment:
Fig. 1 is the departing reducer structure schematic representation of worm screw
The departing retarder of the utility model worm screw is achieved in that sees Fig. 1, and 1 is casing among the figure; 2 is worm gear; 3 is worm-wheel shaft; 4 is input shaft; 5 is coupling; 6 is worm screw; 7 is operating mechanism.Worm gear 2 in the casing 1 and worm screw 6 engagements by operating mechanism 7 controls, can break away from mutually.The position of worm screw 6 is unfixed, and the one end links together by coupling 5 and input shaft 4.Operating mechanism 7 is fixed on the casing 1, is realized by cam structure.During use, when the roller shutter machine scrolled up straw screen or mat, worm gear 2 meshed together with worm screw 6, gave worm gear 2 transmission of power by input shaft 4 by coupling 5; When the roller shutter machine puts down straw screen or mat, can worm screw 6 and worm gear 2 be broken away from by operating mechanism 7, at this moment worm-wheel shaft 3 rotates under the drive of straw screen or mat deadweight, has just finished the action of putting down straw screen or mat without motor like this, i.e. and economize on electricity is convenient again.This retarder also can be finished artificial volume and puts straw screen or mat work when having a power failure.
