The specific embodiment
To the technical scheme in the utility model embodiment be clearly and completely described below, obviously, described embodiment is only a part of embodiment of the present utility model, rather than whole embodiment.Based on the embodiment in the utility model, those of ordinary skills are not making all other embodiment that obtain under creative work prerequisite, all belong to the scope of the utility model protection.
Refer to Fig. 1 and Fig. 2, the utility model embodiment comprises:
A kind of Novel escalator roller, comprise: antifriction-bearing box 1, wheel hub 2 and seal ring 3, described wheel hub 2 comprises the first inner headed face 21 and first periphery 22 of annular, on two sides of described wheel hub 2, be all provided with the first groove 23 of even circle distribution, described the first periphery 22 is provided with a second annular groove 24, described seal ring 3 comprises the second inner headed face 31, described the second inner headed face 31 is provided with a first annular projection 32 matching with described the second groove 24, described wheel hub 2 is fixedly connected on described antifriction-bearing box 1, described seal ring 3 is fixedly connected with described wheel hub 2 with the first projection 32 by the second groove 24.
By multiple the first grooves 23 are set on wheel hub 2, meeting under the prerequisite of roller bearing capacity, reduce the overall weight of roller, save material cost, meanwhile, reduced the noise in roller operational process, and the first groove 23 is that uniform circle distribution is on two sides of wheel hub 2, make in the process of escalator operation, the bearing capacity balance of wheel hub 2, is not easy to damage.The installation of the second groove 24 and the first projection 32 coordinates, and makes in the process of escalator operation, and seal ring 3 can not be shifted with wheel hub 2, good operation stability.
In addition, described Novel escalator roller also comprises two circular seal cover caps 4, two seal cover caps 4 are fixedly connected on respectively the both sides of described antifriction-bearing box 1, and described seal cover cap 4 is provided with the fixing muscle 41 of a ring shape towards the direction of antifriction-bearing box 1, described fixing muscle 41 is provided with a second annular projection 42.
