Abstract
The utility model discloses a kind of rolling door Flywheel disc with roller bearing, comprise disk body and the whirligig being installed on described disk body center, described whirligig comprises roller bearing and two cover plates that is provided with central through hole, the periphery, middle part of described roller bearing is provided with bulge loop, the middle part of two described cover plates is equipped with through hole, on described cover plate, the position be positioned at outside described through hole is provided with annular groove, the external diameter of described annular groove is slightly larger than the external diameter of described bulge loop, the two ends of described roller bearing are each passed through the through hole of two described cover plates, in the space that the annular groove that described bulge loop is placed in two described cover plates surrounds.Spinfunction can be realized owing to adopting plastic processing, so rolling door Flywheel disc described in the utility model lightweight, cost is low, under the prerequisite of normal spinfunction not affecting rolling door, reduce the cost of rolling door user, therefore there is larger range of application.
Description
Technical field
The utility model relates to a kind of rolling door Flywheel disc, particularly relates to a kind of rolling door Flywheel disc of band roller bearing of non-traditional bearing arrangement.
Background technology
Rolling door Flywheel disc, for being arranged on the two ends of rolling door, has the function bearing rolling door weight and rotation.Traditional rolling door Flywheel disc comprises disk body and is installed on the whirligig in disk body centre, its whirligig is made up of bearing and rotating shaft, general employing ball bearing, ball bearing and rotating shaft generally all adopt metal material to make, so weight is comparatively large, cost is higher, also there is ball in addition and damage and not revolvable risk.
Utility model content
The purpose of this utility model is just the rolling door Flywheel disc of the band roller bearing providing a kind of non-ball bearing structure in order to solve the problem.
The utility model is achieved through the following technical solutions above-mentioned purpose:
A kind of rolling door Flywheel disc with roller bearing, comprise disk body and the whirligig being installed on described disk body center, described whirligig comprises roller bearing and two cover plates that is provided with central through hole, the periphery, middle part of described roller bearing is provided with bulge loop, the middle part of two described cover plates is equipped with through hole, on described cover plate, the position be positioned at outside described through hole is provided with annular groove, the external diameter of described annular groove is slightly larger than the external diameter of described bulge loop, the two ends of described roller bearing are each passed through the through hole of two described cover plates, in the space that the annular groove that described bulge loop is placed in two described cover plates surrounds.
In said structure, roller bearing is equivalent to traditional rotating shaft, two cover plates are equivalent to traditional bearing, the space that the annular groove of two cover plates surrounds is carried out spacing to the bulge loop of roller bearing, the bulge loop of roller bearing can rotate in this space simultaneously, thus form the rotary motion similar with traditional bearing, realize similar spinfunction.Why this structure can replace traditional bearing, is that its rotary speed requires very low, so can replace because the weight of rolling door is not very large.
In order to the contact area as far as possible between reduction roller bearing and cover plate and frictional force, described roller bearing is cydariform small in the end and big in the middle, and described bulge loop is placed in maximum outside diameter place, middle part.
Coordinate between cover plate and roller bearing more closely to make two and realize accurate limiting, first described cover plate is greater than second described cover plate, the peripheral projection of first described cover plate forms groove, and second described cover plate entirety is placed in the groove of first described cover plate.
For the ease of installing, the periphery of two described cover plates is evenly provided with four mounting lugs, and described mounting lug is provided with screw, and two described cover plates are installed on described disk body by described mounting lug.
In order to save cost, two described cover plates and described roller bearing all adopt rigid plastics to be made.
The beneficial effects of the utility model are:
Spinfunction can be realized owing to adopting plastic processing, so rolling door Flywheel disc described in the utility model lightweight, cost is low, under the prerequisite of normal spinfunction not affecting rolling door, reduce the cost of rolling door user, therefore there is larger range of application.
Accompanying drawing explanation
Fig. 1 is the roller bearing of the rolling door Flywheel disc of band roller bearing described in the utility model and cover plate perspective view when assembling;
Fig. 2 is the perspective view after the roller bearing of the rolling door Flywheel disc of band roller bearing described in the utility model and cover plate are assembled;
Fig. 3 is the perspective view of the rolling door Flywheel disc of band roller bearing described in the utility model.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail:
As Fig. 1, shown in Fig. 2 and Fig. 3, the rolling door Flywheel disc of band roller bearing described in the utility model comprises disk body 9 and is installed on the whirligig of center of disk body 9, described whirligig comprises the roller bearing 3 that is provided with central through hole (unmarked in figure), first cover plate 5 and the second cover plate 2, roller bearing 3 is broad in the middle, cydariform small in ends, the periphery at the maximum outside diameter place, middle part of roller bearing 3 is provided with bulge loop 4, the middle part of the first cover plate 5 and the second cover plate 2 is equipped with through hole (unmarked in figure), on first cover plate 5 and the second cover plate 2, the position be positioned at outside through hole is equipped with annular groove 6 (wherein the annular groove 6 of the second cover plate 2 is downward in FIG in fact, what see in figure is the bottom of annular groove 6), the external diameter of annular groove 6 is slightly larger than the external diameter of bulge loop 4, the two ends of roller bearing 3 are each passed through the through hole of the first cover plate 5 and the second cover plate 2, in the space that the annular groove 6 that bulge loop 4 is placed in the first cover plate 5 and the second cover plate 2 surrounds, the peripheral projection that first cover plate 5 is greater than the second cover plate 2, first cover plate 5 forms groove 7, and the edge shape of groove 7 is consistent and bigger with the edge shape of the second cover plate 2, and the second cover plate 2 entirety is placed in the groove 7 of the first cover plate 5, the periphery of the first cover plate 5 and the second cover plate 2 is evenly provided with four mounting lugs 1, and mounting lug 1 is provided with screw 8, and the first cover plate 5 and the second cover plate 2 are installed on disk body 9 by mounting lug 1, and disk body 9 is provided with the installing hole 10 corresponding with screw 8, first cover plate 5, second cover plate 2 and roller bearing 3 all adopt rigid plastics to be made.
After assembling this rolling door Flywheel disc, the central through hole of cross bar through roller bearing 3 of rolling door will be installed, cross bar is fixedly mounted on above doorframe, the both sides of rolling door door curtain are arranged on the disk body 9 of this rolling door Flywheel disc, when opening and closing rolling door, manually promote rolling door door curtain up or down, disk body 9 will be driven to rotate relative to roller bearing 3, realize the object of packing up door curtain or decontroling door curtain.
Above-described embodiment is preferred embodiment of the present utility model; it is not the restriction to technical solutions of the utility model; as long as without the technical scheme that creative work can realize on the basis of above-described embodiment, all should be considered as falling within the scope of the rights protection of the utility model patent.
