Abstract
An arrangement in drive machinery of a travelator, moving walkway, escalator or similar apparatus, includes at least a drive motor, at least one handrail with a handrail belt, a support element supporting the handrail and a drive belt connecting rotational movement of the drive motor to the support element. The support element comprises a supporting wheel, having a rim and adapted for use by the drive belt which is fitted to the rim of the support element.
Claims10
An arrangement in drive machinery of a travelator, moving walkway, escalator or similar apparatus, comprising:
- at least a drive motor;
- at least one handrail with a handrail belt;
- a support element comprising a supporting wheel having a rim supporting a bend section of the handrail belt;
- a drive belt fitted to the rim of the supporting wheel and connecting rotational movement of the drive motor to the support element, wherein the rim of the supporting wheel has a radius that is substantially equal to or less than a radius of curvature of an inner contact surface of the handrail belt at the bend section.
A method for replacing the drive belt of a handrail incorporated in a travelator, moving walkway, escalator or similar apparatus, the drive belt being arranged in a drive machinery of the travelator, moving walkway, escalator or similar apparatus, the drive machinery comprising at least a drive motor, the handrail including a handrail belt being supported by a support element having an axis of rotation, wherein the drive belt connects rotational movement of the drive motor to the support element, the method comprising:
- fitting the drive belt to the support element in connection when placing the drive belt into position;
- and
- rotating the support element around its axis of rotation until the drive belt is placed around the support element.
A support element for a handrail belt of a handrail of a travelator, moving walkway, escalator or similar apparatus, comprising:
- a supporting wheel having a rim, wherein the supporting wheel defines a coupling element to couple and install a drive belt of the supporting wheel onto the rim of the supporting wheel in connection with placing the drive belt into position for imparting rotational movement of a drive motor to the supporting wheel, wherein the coupling element comprises an installation groove formed in the supporting wheel and extending essentially inwards from the rim of the supporting wheel, the installation groove being adapted to receive the drive belt in connection with placing the drive belt into position around the supporting wheel.
