Self-braking gear and people conveyor comprising a self-braking gear
A self-braking gear (2) comprises: an input shaft (4), an output shaft (6), a braking mechanism (8), which is configured for braking the output shaft (6), and a planetary gear (10). The planetary gear (10), which is connected between the input shaft (4) and the output shaft (6), is configured to activate the braking mechanism (8) in order to brake the output shaft (6), when no torque is provided via the input shaft (4). The self-braking gear (2) may be employed in a people conveyor (50) such as an escalator.
Brake system for passenger conveyors
A system for braking an escalator or moving walkway includes a handrail and passenger support in registration with one another so as to move together. A braking tensioner selectively increases tension in the handrail during operation. The increased tension serves to frictionally brake the handrail and hence the passenger support. The braking tensioner may be located in any of various locations depending upon system design, and may be driven in any suitable manner, e.g., hydraulically, electrically, electromagnetically, and so on. Frictional wear on the handrail is reduced by the fact that the described braking system spreads the frictional load over a large area of the handrail, e.g., the many locations where the handrail contacts the underlying support throughout its length.
Passenger conveyor
A passenger conveyor (10) comprises a plurality of treads (16) interconnected to form an endless tread band (17), the passenger conveyor (10) comprising a chain and sprocket drive system including at least two drive sprockets (24a, 24b), each drive sprocket (24a, 24b) drivingly coupled to a respective drive chain (20a, 20b), each drive sprocket (24a, 24b) having a predetermined number of drive sprocket teeth (38a, 38b) positioned at a predetermined drive sprocket teeth pitch (a, b) with respect to each other, wherein the drive sprockets (24a, 24b) are configured to rotate with the same angular velocity, but at a predetermined phase difference () with respect to each other.
PASSENGER-TRANSPORTING SYSTEM WITH A DEVICE FOR DETERMINING THE OPERATING STATE
A device serves for determining the speed of a passenger-transporting system. The device includes an arrangement of auxiliary elements and a sensing device. The arrangement of the auxiliary elements rotates, in a manner corresponding to a movement of the passenger-transporting system. The sensing device can sense whether an auxiliary element is, or is not, located at a certain sensing location. The auxiliary elements are of a first configuration type and a second configuration type. The sensing device can sense whether an auxiliary element is of the first configuration type or of the second configuration type. Furthermore, the sensing device can assign an auxiliary element of the first configuration type and an auxiliary element of the second configuration type to one another such that the direction of rotation can be determined from the order in which the auxiliary elements are sensed.
PEOPLE CONVEYOR, CONVEYING BAND AND CONVEYING ELEMENT OF A PEOPLE CONVEYOR
A conveying element (4) is employed in a conveying band (2) of a people conveyor (50) comprising at least one horizontal portion (81, 83, 85), includes a tread (6) and a riser (8). The conveying element (4) is configured such that the riser (8) at least partly forms an intermediate tread surface (74) in the at least one horizontal portion (81, 83, 85).
Belt-driven people conveyor
A people conveyor (2) comprises at least one belt (4) extending in a longitudinal conveying direction, a plurality of webs (6) attached to the belt (4), and a plurality of transportation elements (14). Each of the transportation elements (14) comprises at least one connection portion (20). The connection portions (20) extend laterally from the transportation elements (14) and are configured for being connected with at least one of the webs (6) for attaching the respective transportation element (14) to the belt (4).
SELF-LOCKING GEAR AND PEOPLE CONVEYOR COMPRISING A SELF-LOCKING GEAR
A people conveyor (10) comprises: a chain of conveyance elements (12), which are configured for conveying people; a drive unit (14), which is configured for driving the chain of conveyance elements (12); and a self-locking gear (20; 40), which is configured to lock when no torque is transmitted from the drive unit (14) to the chain of conveyance elements (12).
SELF-BRAKING GEAR AND PEOPLE CONVEYOR COMPRISING A SELF-BRAKING GEAR
A self-braking gear (2) comprises: an input shaft (4), an output shaft (6), a braking mechanism (8), which is configured for braking the output shaft (6), and a planetary gear (10). The planetary gear (10), which is connected between the input shaft (4) and the output shaft (6), is configured to activate the braking mechanism (8) in order to brake the output shaft (6), when no torque is provided via the input shaft (4). The self-braking gear (2) may be employed in a people conveyor (50) such as an escalator.
Brake for use in passenger conveyor system
A brake for use in a passenger conveyor system is provided. The passenger conveyor system includes a drive system operable to drive a drive component in a desired direction. The brake is actuated by a reversal in direction of movement of the drive component.
