Detailed description of the invention
Be clearly and completely described to the technical scheme in the embodiment of the present invention below, obviously, described embodiment is only a part of embodiment of the present invention, instead of whole embodiments.Based on the embodiment in the present invention, those of ordinary skill in the art, not making other embodiments all obtained under creative work prerequisite, belong to the scope of protection of the invention.
Refer to Fig. 1 to Fig. 2, the embodiment of the present invention comprises:
A kind of aluminium core escalator roller, comprise: antifriction-bearing box 1, aluminium core 2, wheel hub 3 and seal ring 4, described aluminium core 2 arranges cylindrical, described aluminium core 2 comprises the first inner headed face 21 and the first periphery 22, described first periphery 22 is provided with the groove 23 of a ring shape, described wheel hub 3 comprises the second inner headed face 31 and the second periphery 32, described second inner headed face 31 is provided with the projection 33 of the annular matched with described groove 23, described seal ring 4 comprises the 3rd inner headed face 41 and the 3rd periphery 42, described second periphery 32 matches with described 3rd inner headed face 41, described aluminium core 2 is fixedly connected on described antifriction-bearing box 1, described wheel hub 3 is fixedly connected between described aluminium core 2 and described seal ring 4.Compared with roller of the prior art, wheel hub 3 is also fixedly connected with between seal ring 4 and aluminium core 2, by groove 23 and protruding 33 coordinate, second inner headed face 31 of wheel hub 3 is connected with the first periphery 22 of aluminium core 2, by matching of the second periphery 32 and the 3rd inner headed face 41, wheel hub 3 is fixedly connected with seal ring 4, and this structure not only reduces the operation noise of roller, the problem also effectively preventing seal ring 4 and aluminium core 2 from easily ftractureing, improves the service life of roller.
In addition, described aluminium core escalator roller also comprises two collars 5, described collar 5 comprises back-up ring 51 and two guard hoops 52 of circular arc, and the two ends of described circular arc back-up ring 51 are fixedly connected with a guard hoop 52 respectively, and described collar 5 is fixedly connected on the both sides of described antifriction-bearing box 1.Collar 5, for being connected with the staircase of escalator, improves the Joint strenght of roller and staircase.
In addition, the central axis of described collar 5 parallels with the central axis of described antifriction-bearing box 1 and does not coincide, and make roller in the process run, force dispersion, is not easy the cracking causing seal ring 4.
In addition; described wheel hub 3 is identical with the thickness of described seal ring 4; the thickness of described aluminium core 2 is less than the thickness of described seal ring 4; as shown in Figure 2; the thickness of seal ring 4 and wheel hub 3 is greater than the thickness of aluminium core 2, ensures that aluminium core 2 cracking is less likely to occur and damages, while can better protecting aluminium core 2; again reduce the noise in roller operational process, improve the bearing capacity of aluminium core 2.
In addition; the cross section of described groove 23 is isosceles trapezoid; the length of the bottom of described groove 23 is less than the length at the top of described groove 23; aluminium core 2 and wheel hub 3 were better fixed together with coordinating of projection 33 by groove 23; even if in the process that roller runs; also protect the heavy keying fit of aluminium core 2 and wheel hub 3, prevent wheel hub 3 to be shifted, improve the service life of aluminium core 2.
In addition, second periphery 32 cross section of described wheel hub 3 is circular arc, same in order to better wheel hub 3 is fixedly connected with seal ring 4, second periphery 32 of wheel hub 3 is provided with the cross section structure of circular arc, wheel hub 3 edge is greater than the distance of center to the central axis of antifriction-bearing box 1 of wheel hub 3 to the distance of the central axis of antifriction-bearing box 1, because described second periphery 32 matches with described 3rd inner headed face 41, so the edge of the 3rd inner headed face 41 is less than the distance of center to the central axis of antifriction-bearing box 1 of the 3rd inner headed face 41 to the distance of the central axis to antifriction-bearing box 1, the second periphery 32 is relied on to coordinate with the arc surface of the 3rd inner headed face 41, even if in the process that roller runs, also mutual movement can not be there is in wheel hub 3 and seal ring 4, improve the safety and stability of the connection of wheel hub 3 and seal ring 4, thus improve the smoothness of roller operation.
In addition, the central axis of described aluminium core 2, wheel hub 3 and seal ring 4 and the central axis of described antifriction-bearing box 1 coincide, and improve the smoothness of roller operational process.
In addition, described seal ring 4 is made by polyurethane material, and described wheel hub 3 is made for polyamide material.Polyurethane material excellent performance, has that fabulous quality is light, resistance to abrasion good, water resistance is good, and polyamide material wear resisting property is good, friction coefficient is little.
Aluminium core escalator roller of the present invention, by being fixedly connected with wheel hub between seal ring and aluminium core, reducing the noise in roller operational process, improves the stability of roller, effectively prevents the cracking of aluminium core or seal ring, improves the service life of roller.
Be different from prior art, aluminium core escalator roller noise of the present invention is low, good stability, degree of operating steadily good, effectively prevent the cracking of aluminium core or seal ring, improve the service life of roller.
The foregoing is only embodiments of the invention; not thereby the scope of the claims of the present invention is limited; every utilize description of the present invention to do equivalent structure or equivalent flow process conversion; or be directly or indirectly used in other relevant technical field, be all in like manner included in scope of patent protection of the present invention.
