Hengda Fuji Elevator Company Invention Patent -"A Rack-type Escalator”
With the development of the national economy, escalators have been widely used in places with high traffic (such as shopping malls, stations, etc.).
The traditional chain escalator has the following drawbacks: the transmission chain is subjected to a huge load at the upper bending portion, and in order to ensure the normal operation of the escalator, the size of the transmission component is designed to be larger, resulting in a larger space and higher power consumption. The traditional chain escalator drive host must be installed in the upper room, resulting in a narrow inspection space; traditional chain escalator due to the structural characteristics of the restricted transmission components, the main use of worm reducer, transmission efficiency is low. The invention patent adopts a new escalator transmission method, and the load on the upper bending part of the transmission rack is lower than the chain of the escalator of the chain type, and has the advantages of small space occupied by the transmission parts and low power consumption. Experiments show that Compared with the chain escalator, the energy consumption is reduced by 20%. The drive host is installed in the middle of the escalator truss, which has the advantage of large maintenance space and convenient maintenance. The use of secondary helical gear reducer, high transmission efficiency, reaching 95% or more.
