Abstract
The utility model discloses a wheel for escalator, which comprises a wheel and an outer ring; the wheel is two concave steel skeleton structures with hole; the wheel is interconnected through bearings in the hole; the material of outer ring is polyurethane, thermoplastic polyurethane or injection acrylonitrile-butadiene rubber. The utility model has the advantages of simple , light with strong bearing capability, the elastic material of outer ring can being used in accordance with requirements of a variety of materials, and reducing the manufacturing costs greatly .
Description
(1) technical field
The utility model relates to the gearing technical field, specifically is meant a kind of escalator roller.
(2) background technology
At present, the roller that is installed on the escalator step is divided into front wheel and rear roller (respectively pacifying 2 on each step), and the wheel hub of front wheel is after heat treatment to make solid construction with the forging blank of high-quality steel, and every wheel hub weight reaches gram more than 200; The wheel hub of rear roller is to use the die casting aluminium structure, though weight gentlier, manufacturing cost is not low yet, and the process for making contaminated environment.The outer ring of roller is with injecting government rubber manufacturing, 90 °～95 ° of shore hardnesses.
In actual applications, the performance of pair roller proposes very high requirement.Every roller must be under certain load (300 kilograms of front wheels, 200 kilograms of rear rollers), operation any damage phenomenon do not occur in 50 hours continuously under 34 meters/minute linear velocity, also required the roller poach 24 hours before commissioning test, placed upper stage test in 24 hours again.Therefore, the present escalator step that uses roller wheel hub structure heaviness, manufacturing cost height.
(3) summary of the invention
The purpose of this utility model is exactly in order to solve above-mentioned the deficiencies in the prior art part, and a kind of escalator roller is provided.This roller structure is simple, and is in light weight, low cost of manufacture.
A kind of escalator roller described in the utility model comprises wheel hub and outer ring, it is characterized in that, described wheel hub is to be interconnected by the bearing in the endoporus by two matrix steel skeleton constructions that have an endoporus to form.
In order to realize the utility model better, the material of described outer ring is polyurethane, thermoplastic polyurethane or injection government rubber.
The utility model compared with prior art has following advantage and beneficial effect:
1. the utility model structure is very simple, owing to adopt the matrix steel skeleton construction, thereby weight alleviates greatly, but load-carrying capacity is still very strong.
2. the elastomeric material of the utility model outer ring can adopt multiple material preparation according to operating needs.
3. the utility model is because material uses minimizing, and manufacturing cost reduces greatly.
(4) description of drawings
Fig. 1 is a matrix steel skeleton construction scheme drawing of the present utility model;
Fig. 2 is a structural representation of the present utility model.
(5) specific embodiment
Below in conjunction with drawings and Examples, the utility model is done detailed description further.
As illustrated in fig. 1 and 2; steel frame is stamped to form with forging die with high-quality or the general steel plate (or electroplating one deck corrosion protection layer) of thin 1～1.6mm; the centre has endoporus 2; there is the bossing 3 of 3mm can strengthen the rigidity and the pressure resistance at this position on the steel frame outer ring; endoporus 2 presses with bearing 4 and cooperates, and has shoulder 1 that bearing 4 is blocked.Two steel frame tape spools hold has combined just to become a complete wheel hub, wheel hub after treatment in the middle of and the outer ring can inject polyurethane elastomer, thermoplastic polyurethane or government rubber 5 (user can consider factors such as performance, price, supply producer, determine to adopt wherein a kind of technology at last), just can make front wheel or rear roller, its performance can satisfy test and operating needs.As mentioned above, can realize the utility model preferably.
Claims (2)
1. an escalator roller comprises wheel hub and outer ring, it is characterized in that, described wheel hub is to be interconnected by the bearing in the endoporus by two matrix steel skeleton constructions that have an endoporus to form.
2. a kind of escalator roller according to claim 1 is characterized in that, the material of described outer ring is polyurethane, thermoplastic polyurethane or injection government rubber.
