Abstract
An eccentric crankshaft is connected to a rotary driving device, and a rocking unit is connected to the eccentric crankshaft. Pin roller rolling gear teeth, each having a trochoid tooth-shape, are provided in the rocking unit. When the rocking unit rocks in accordance with eccentric rotation of the eccentric crankshaft, the trochoid shape of the pin roller rolling gear teeth meshes with pin rollers and thus gives a thrust to the pin rollers, thereby driving footsteps.
Claims16
A passenger conveyer system, comprising:
- a footstep guide rail provided in a structure;
- a plurality of footsteps which move along the footstep guide rail;
- a chain which connects the plurality of footsteps with one another in an endless circular manner;
- and
- a trochoid mechanism having a rocking unit, the mechanism including pin rollers which relatively drive linearly in accordance with the rock of the rocking unit and a trochoid tooth-shaped section which meshes with the pin rollers and which are disposed between the chain and the rocking unit.

A passenger conveyer system, comprising:
- a footstep guide rail provided for a structure;
- a plurality of footsteps which move along the footstep guide rail;
- a chain which connects with the plurality of footsteps in an endless circular manner;
- a rotary driving device fixed to the structure;
- and
- driving means for converting rotary motion transmitted through an eccentric shaft from the rotary driving device into rocking movement of a rocking unit and applying a thrust from the rocking unit through a trochoid tooth-shaped section which meshes with pin rollers, some provided in the rocking unit and others provided in the chain, and for providing a plurality of the rocking units so as to apply a thrust to the chains connected on both sides in a width direction of the footsteps, thereby driving the plurality of the rocking units through the eccentric shaft from the rotary driving device.
