A governor includes a housing, a pulley, a belt, a first flyweight, and second flyweight. The housing defines a housing cavity. The pulley is disposed at least partially within the housing cavity. The belt is in contact with the pulley. The belt is operable to rotate the pulley at a rotational speed. The first and second flyweights are pivotably connected to the pulley, and are biased towards one another. At least a portion of the first and second flyweights are operable to move away from the pulley when the rotational speed of the pulley is increasing toward a predetermined threshold rotational speed. The first and second flyweights are operable to contact the housing, and thereby transmit rotational energy to the housing, when the rotational speed of the pulley is equal to at least the predetermined threshold rotational speed.

Governor for controlling the speed of a hoisted object relative to a guide member

A mechanism for use in an elevator governor assembly including a ground configured to rotate about a ground axis, three or more circumferentially overlapping cams each pivotally attached to the ground at one of three or more ground pivot points radially spaced from the ground axis, and a plurality of links pivotally attaching the three or more cams to one another at a plurality of link pivot points. The circumferentially overlapping cams form a substantially contiguous circular ring about the ground axis. The interconnection of the ground, the cams, and the links form a generally circular mechanism.

Governor sheave with an overlapping flyweight system

An elevator machine () includes a machine shaft () and a sheave () that rotates with the machine shaft (). A motor () selectively rotates the machine shaft (). A brake () having at least one brake armature () selectively moves a brake rotor () coupled for rotation with the shaft () between a braking position and a released position. The brake rotor () selectively contacts a braking surface () formed directly on a housing () to resist rotation of the machine shaft ().

Elevator machine with integrated brake surface

An elevator brake () rotor for use in an elevator machine () includes a non-metallic elevator brake hub () and a metal flange (), both of which have an opening with a splined portion for guiding axial movement of the rotor along a rotable shaft (). This arrangement reduces metal-to-metal contact between the rotor and shaft and reduces noise.
