The invention discloses a hollow stepped shaft which comprises a middle hollow shaft. The middle hollow shaft is provided with two symmetrical first elastic pins. The middle hollow shaft is sleeved with shaft sleeves which are located outside the first elastic pins. The sides, provided with positioning pin holes, of the shaft sleeves are provided with gaskets, and the other sides of the shaft sleeves are provided with springs. One side of each gasket is positioned and fixed through a plug pin inserted into the corresponding first elastic pin. Bushing sleeves are arranged between the shaft sleeves and the gaskets. The two ends of the middle hollow shaft are provided with second elastic pins correspondingly. Pin shafts are inserted to the two sides of the middle hollow shaft correspondingly,and the pin shafts are fixed through plug pins inserted into the second elastic pins. The exposed parts of the pin shafts are sleeved with sleeves, the sleeves are sleeved with main wheels, the two sides of each main wheel are provided with inner chain plates arranged in parallel and penetrating through the pin shafts correspondingly, and the outer sides of the inner chain plates are provided with outer chain plates penetrating through the pin shafts correspondingly. The hollow stepped shaft is low in cost, high in university, simple in structure and convenient to machine.
Description
technical field [0001] The invention relates to a step shaft suitable for the step chain of an automatic escalator, in particular to a hollow step shaft with high versatility and low price. Background technique [0002] With the rapid development and application of escalators, the competition among escalator manufacturers is becoming more and more fierce. Various escalator manufacturers have launched their own products one after another, and a variety of step shaft forms with different structures have appeared. Some of the step shaft structures are complex and uneconomical, and their versatility is extremely low, which cannot meet the requirements of most different manufacturers. Contents of the invention [0003] The object of the present invention is to provide a hollow stepped shaft with high versatility and low price in order to overcome the deficiencies of the prior art. [0004] In order to achieve the above object, the technical solution adopted by the present inve...
