Abstract
An automatic staircase main transmission shaft relates to the technical field of the automatic staircase, especially relates to the technical field of the main transmission shaft controlling the operation of the automatic staircase. The utility model comprises supporting bases, a main shaft, a shaft base, big chain wheels, a small chain wheel, a double-bank chain wheel, and an oil pipe. A supporting base is connected with each of the two ends of the main shaft along the length direction by bolts. The shaft pipe is disposed on the outer periphery of the main shaft along the length direction. The big chain wheel is disposed on each of two ends of the shaft pipe along the length direction, and is provided with the oil pipe. The small chain wheel is disposed on the shaft pipe, and one of the bolts disposed on the outside of one of the big chain wheel is connected with the double-bank chain wheel. The utility model has advantages of simple structure, long service lifetime, stable and safe operation, convenient installation and maintenance.
Description
Technical field
The utility model relates to the technical field of escalator, relates in particular to the technical field of the main driving axle of control escalator operation.
Background technology
Escalator is to have the circular flow step, the fixedly driven by power equipment of be used for tilting up or down conveying people or goods.Along with a large amount of utilizations of escalator, higher requirement has been proposed all in stability and the safety that moves.Because the circular flow of escalator realizes by conduction chain and sprocket wheel, so the service requirement and the intensity of main driving axle has been proposed requirement, wants simultaneously to guarantee staircase operation level degree.
Summary of the invention
The utility model purpose provides a kind of simple in structure, long service life, stable and safe in operation, escalator main driving axle easy to installation and maintenance.
A kind of escalator main driving axle, it is characterized in that comprising supporting seat, main shaft, central siphon, hinge wheel, minor sprocket, duplex chain wheel, oil pipe, two ends difference bolted connection supporting seat along the main axis length direction, periphery along the main axis length direction is provided with central siphon, the two ends that are positioned at the central siphon length direction are provided with hinge wheel respectively, and oil pipe is set respectively on each hinge wheel; Minor sprocket is set on the central siphon, is positioned at the outside bolted connection duplex chain wheel of one of them hinge wheel.
Minor sprocket of the present utility model is connected with central siphon by flat key.
Between oil pipe of the present utility model and the main shaft tilting bearing is set.
The utility model adopts technique scheme, compared with prior art has following advantage:
1, the utility model connects hinge wheel at the main shaft head bearing, connects minor sprocket on central siphon, has improved the stability of operation on the one hand, is easy for installation and maintenance on the other hand.
2, connect oil pipe on the main shaft of the present utility model, improved the stable of operation, and at any time main shaft has been lubricated, prolonged the service life of escalator.
3, the bolted connections that adopt between each parts of the present utility model use tightening seal washer more in needs leak free position, and simple in structure, Assembly ﹠Disassembly is convenient.
