Modular chain newel with standard bearing

摘要

A roller bearing and newel guide assembly (30) for a newel (24) in an escalator (10) has a newel guide (32), a roller chain (34), and a spring (40) connected between the roller chain (34) and the newel guide (32) to provide tension to the roller chain (34). The roller chain (34) comprises a series of interlinked chain units (36). Each chain unit (36) includes a frame (78), at least one roller bearing (72), and a pin (76) for connecting the roller bearing (72) to the frame (78). Each chain unit (36) has a female connector (62) and a male connector (64), which allow each chain unit (36) to connect to an adjacent chain unit (36) to form the roller chain (34).

主权项

1. A handrail assembly for a newel of a passenger conveyor, the assembly comprising:
a handrail belt that travels around the newel; a newel guide; a roller chain having a first end and a second end connected to the newel guide, the roller chain comprising a series of interlinked chain units that are each separately removable from the roller chain, wherein each chain unit comprises:
a frame having a first end and a second end;a hook at the first end;a loop at the second end; anda roller bearing mounted between the first end and the second end;wherein the chain units are connected by engagement of the hook of one of the chain units with the loop of an adjacent chain unit; and a spring connected between the first end of the roller chain and the newel guide to provide tension to the roller chain in order to maintain contact between the roller bearings and the handrail belt; wherein the hook is integrally formed with the frame of each chain unit, and the loop is a separate piece that can be connected to the frame of each chain unit.
