Abstract
The invention discloses a main transmission shaft of an escalator, and relates to the technical field of escalators, in particular to the technical field of main transmission shafts for controlling operations of escalators. The main transmission shaft comprises support seats, a main shaft, a shaft tube, large chain wheels, small chain wheels, double-row chain wheels and oil tubes, wherein the support seats are connected at two ends along the length direction of the main shaft by bolts respectively; the shaft tube is arranged on the periphery along the length direction of the main shaft; the large chain wheels are arranged at two ends along the length direction of the shaft tube respectively; the oil tubes are arranged on the large chain wheels respectively; the small chain wheels are arranged on the shaft tube; and the bolts positioned outside one of the large chain wheels are connected with the double-row chain wheels. The main transmission shaft of the escalator fulfills the purposes of simple structure, long service life, stable and safe operation and convenient installation and maintenance.
Description
Technical field
The present invention relates to the technical field of escalator, relate 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 through 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 object of the invention 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, and 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 invention is connected with central siphon through flat key.
Between oil pipe of the present invention and the main shaft tilting bearing is set.
The present invention adopts technique scheme, compared with prior art has following advantage:
1, the present invention connects hinge wheel at the main shaft head bearing, on central siphon, connects minor sprocket, 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 invention, 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 invention use tightening seal washer more in needs leak free position, and simple in structure, Assembly &Disassembly is convenient.
Description of drawings
Fig. 1 is a kind of structural representation of the present invention.
The specific embodiment
Below in conjunction with accompanying drawing technical scheme of the present invention is elaborated:
As shown in Figure 1; A kind of escalator main driving axle; Comprise supporting seat 1, main shaft 2, central siphon 3, hinge wheel 4, minor sprocket 5, duplex chain wheel 6, oil pipe 7, the bolted connection supporting seat 1 respectively along the two ends of main shaft 2 length directions is provided with central siphon 3 along the periphery of main shaft 2 length directions; The two ends that are positioned at central siphon 3 length directions are provided with hinge wheel 4 respectively, on each hinge wheel 4 oil pipe 7 are set respectively; Minor sprocket 5 is set on the central siphon 3, is positioned at the outside bolted connection duplex chain wheel 6 of one of them hinge wheel 4.
As shown in Figure 1, minor sprocket 5 of the present invention is connected with central siphon 3 through flat key 8.
As shown in Figure 1, between oil pipe 7 of the present invention and the main shaft 2 tilting bearing 9 is set.
As shown in Figure 1, the two ends up and down of main shaft 2 of the present invention are bolted connection supporting seat 1 respectively, and the periphery of main shaft 2 is nested with central siphon 3, and the two ends up and down of central siphon 3 are provided with hinge wheel 4 respectively, and hinge wheel 4 is connected through bolt 11 with the end of central siphon 3 respectively.Be connected with minor sprocket 5 through flat key 8 on the central siphon 3.All be connected with oil pipe 7 on each hinge wheel 4, between oil pipe 7 and the main shaft 2 tilting bearing 9 be set, bearing cap shim 10 is set on the tilting bearing 9.In the present embodiment, bolt 12 connection duplex chain wheels 6 are passed through on the top that is positioned at the hinge wheel 4 of upper end.
