The specific embodiment
Below the technical scheme in the embodiment of the present invention is clearly and completely described, obviously, described embodiment is only a part of embodiment of the present invention, rather than whole embodiment.Embodiment based in the present invention, those of ordinary skills, not making all other embodiment that obtain under creative work prerequisite, belong to the scope of protection of the invention.
Refer to Fig. 1 and Fig. 2, the embodiment of the present invention 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 a plurality of the first grooves 23 are set on wheel hub 2, meeting under the prerequisite of roller bearing capacity, reduced 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 fixedly muscle 41 of a ring shape towards the direction of antifriction-bearing box 1, described fixedly muscle 41 is provided with a second annular projection 42.
In addition, on the first inner headed face 21 of described wheel hub 2, be also provided with two the 3rd annular grooves 25, described the 3rd groove 25 with match with the second projection 42 of two seal cover caps 4 respectively.By being connected of the second projection 42 and the 3rd groove 25; by seal cover cap 4 both sides that are fixedly connected on antifriction-bearing box 1 tightly; and the fixedly muscle 41 of seal cover cap 4 is closely fixedly connected with the first inner headed face 21 of wheel hub 2; increased the stationarity of roller in escalator operation process; and seal cover cap 4 can also prevent that moisture, dust or oil stain from entering in antifriction-bearing box 1; thereby protection antifriction-bearing box 1, the service life of prolongation roller.
In addition, described the first groove 23 is evenly distributed between described the first inner headed face 21 and described the first periphery 22, the first groove 23 comprises the 3rd inner headed face 26 and the 3rd periphery 27, and the arc length of described the 3rd periphery 27 is greater than the arc length of described the 3rd inner headed face 26.The first groove 23 has not only reduced the weight of roller, also reduced the material cost of wheel hub 2, stressing conditions for wheel hub 2 in better balance escalator operation process, the arc length that wheel hub 2 is designed to the 3rd periphery 27 is greater than the arc length of described the 3rd inner headed face 26, make wheel hub 2 stressed more even, do not allow to be subject to External Force Acting and ftracture, extending the service life of wheel hub 2.
In addition, described the first groove 23 has 16, and the surface of described the first groove 23 is provided with rounding.These roundings have reduced the fragility of cell body, effectively prevent that wheel hub 2 is in stressed process, and the first groove 23 ftractures.
In addition, described seal ring 3 is made by TPUE material, and resistance to abrasion is good, good corrosion resistance, the service life of having improved roller.
