Abstract
The utility model relates to a pulley, in particular to a punched type pulley which comprises an axle. The axle is fixedly connected with a first wheel disk, a first bent portion which is punched into a first angle is arranged at the outer edge of the first wheel disk, a second wheel disk is fixedly connected to the first wheel disk through a fastening part, a second bent portion which is punched into a second angle is arranged at the outer edge of the second wheel disk, and the first bent portion and the second bent portion are oppositely arranged to form a rope groove. The punched type pulley is composed of the punched first wheel disk and the punched second wheel disk, so that pulley manufacturing production efficiency is improved, consumption of raw materials is greatly reduced, production cost is reduced, and convenience is brought to batch production.
Description
Technical field
The utility model relates to a kind of pulley, relates in particular to a kind of punching type pulley.
Background technique
Pulley is the lever of distortion, and it is simple and mechanical to belong to the lever class, has many uses.The major function of pulley is tractive load, change application of force direction, through-put power etc.Traditional pulley generally is to adopt cast member to be processed into by operations such as turning, plating, long processing time, and turning machining allowance is big, consumptive material is many, the manufacture cost height.
At present, three-dimensional parking device for alleviating the city parking difficulty, is being brought into play more and more important effect with its land use capability efficiently.In three-dimensional parking device, its lifting drive system adopts motor to add steel wire rope type usually, and wire rope wiring device need use pulley.The pulley of its use adopts round steel or nylon rod car system usually, and the cutting surplus is big, and materials consumption is bigger, manufacture cost is higher, and each parking space needs two pulleys at least, and the pulley quantity that several parking spaces need is very big, so the high problem of pulley manufacture cost is anxious to be solved.
The model utility content
Technical problem to be solved in the utility model is: provide a kind of punching type pulley, to solve existing pulley manufacture cost technical problems of high.
For solving the problems of the technologies described above, the technical solution of the utility model is: the punching type pulley, comprise wheel shaft, be fixedly connected with first disc on the described wheel shaft, the outer rim of described first disc is provided with punching press first kink at angle, be fixedly connected with second disc by fastening piece on described first disc, the outer rim of described second disc is provided with punching press second kink at angle, and described first kink and described second kink arrange and form grooving in opposite directions.
As a kind of improvement, described wheel shaft is stepped, and the end face of convex portion offsets on described first disc and the described wheel shaft.
As further improvement, described fastening piece distributes along the gyration center annular array of described wheel shaft.
After having adopted technique scheme, the beneficial effects of the utility model are: because the punching type pulley adopts first disc of punching press and second disc of punching press to be combined to form, thereby not only make the manufacturing efficiency height of pulley, and significantly reduced raw-material consumption, reduced cost of production, be convenient to produce in batches.
Because described wheel shaft is stepped, the end face of convex portion offsets on described first disc and the described wheel shaft, when making pulley, has made things convenient for being connected of first disc and wheel shaft.
Because described fastening piece distributes along the gyration center annular array of described wheel shaft, make win disc and the second disc joint more fastening, stressed more even, improved the reliability that pulley uses.
Description of drawings
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the left view of Fig. 1;
Among the figure: 1, wheel shaft, 11, convex portion, 2, first disc, 21, first kink, 3, fastening piece, 4, second disc, 41, second kink, 5, grooving.
Embodiment
In order to make the purpose of this utility model, technological scheme and advantage clearer, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explaining the utility model, and be not used in restriction the utility model.
Shown in Fig. 1 and Fig. 2 are common, the punching type pulley, comprise wheel shaft 1, be fixedly connected with first disc 2 on the wheel shaft 1, the outer rim of first disc 2 is provided with punching press first kink 21 at angle, first disc 2 can be selected sheet metal for use, be fixedly connected with second disc 4 by fastening piece 3 on first disc 2, fastening piece 3 distributes along the gyration center annular array of wheel shaft 1, make win disc 2 and second disc, 4 joints more fastening, stressed more even, improved the reliability that pulley uses, fastening piece 3 optional bolts etc.; The outer rim of second disc 4 is provided with punching press second kink, 41, the second disc 4 at angle can select sheet metal for use, and first kink 21 and second kink 41 arrange and form grooving 5 in opposite directions.
When making pulley, for convenience being connected of first disc 2 and wheel shaft 1, wheel shaft 1 can be set to stepped, and during installation, the end face of convex portion 11 offsets on first disc 2 and the wheel shaft 1.
The punching type pulley that the utility model provides, because pulley adopts first disc 2 of punching press and second disc 4 of punching press to be combined to form, thereby not only makes the manufacturing efficiency height of pulley, and has significantly reduced raw-material consumption, reduced cost of production, be convenient to produce in batches.
The above only is preferred embodiment of the present utility model; not in order to limit the utility model; all any modifications of within spirit of the present utility model and principle, doing, be equal to and replace and improvement etc., all should be included within the protection domain of the present utility model.
Claims (3)
