Abstract
A drive sprocket assembly is provided. The drive sprocket assembly includes at least one first segment and at least one second segment. Each of the at least one first segment and the at least one second segment is adapted to be removably affixed to a hub of the drive sprocket assembly. Each of the at least one first segment and the at least one second segment includes a top surface and an inner surface extending away from the top surface. The inner surface includes a stepped configuration. The inner surface is adapted to at least partially abut a raised portion of the hub and an outer surface of the hub. The drive sprocket assembly also includes a tooth segment provided on the top surface of each of the at least one first segment and the at least one second segment respectively.
Claims19
A drive sprocket assembly comprising:
- a hub including:
- an inner surface;
- an outer surface;
- and
- a raised portion provided centrally along the outer surface, the raised portion including:
- a top surface;
- a first side surface extending between the top surface and the outer surface;
- and
- a second side surface disposed opposite the first side surface, the second side surface extending between the top surface and the outer surface;
- at least one first segment and at least one second segment, each of the at least one first segment and the at least one second segment adapted to be removably affixed to the hub, each of the at least one first segment and the at least one second segment including:
- a top surface;
- and
- an inner surface including:
- a first portion extending away from the top surface;
- a second portion extending away from the first portion, the second portion adapted to at least partially abut the top surface of the raised portion;
- a third portion extending away from the second portion, the third portion adapted to at least partially abut the first side surface and the second side surface of the raised portion respectively;
- and
- a fourth portion extending away from the third portion, the fourth portion adapted to at least partially abut the outer surface;
- and
- a tooth segment provided on the top surface of each of the at least one first segment and the at least one second segment respectively.
A drive sprocket assembly comprising:
- at least one first segment and at least one second segment, each of the at least one first segment and the at least one second segment adapted to be removably affixed to a hub of the drive sprocket assembly, each of the at least one first segment and the at least one second segment including:
- a top surface;
- and
- an inner surface extending away from the top surface, the inner surface having a stepped configuration, wherein the inner surface is adapted to at least partially abut a raised portion of the hub and an outer surface of the hub, wherein each of the at least one first segment and the at least one second segment includes a wedge-shaped configuration such that a length of the top surface thereof is greater than a length of the inner surface thereof respectively;
- and
- a tooth segment provided on the top surface of each of the at least one first segment and the at least one second segment respectively.
A drive assembly for an electric rope shovel, the drive assembly comprising:
- a housing;
- a drive shaft rotatably mounted within the housing;
- and
- a drive sprocket assembly mounted on the drive shaft, the drive sprocket assembly including:
- a hub including:
- an inner surface adapted to receive the drive shaft therein;
- an outer surface;
- and
- a raised portion provided centrally along the outer surface, the raised portion including:
- a top surface;
- a first side surface extending between the top surface and the outer surface;
- and
- a second side surface disposed opposite the first side surface, the second side surface extending between the top surface and the outer surface;
- at least one first segment and at least one second segment, each of the at least one first segment and the at least one second segment adapted to be removably affixed to the hub, each of the at least one first segment and the at least one second segment including:
- a top surface;
- and
- an inner surface including:
- a first portion extending away from the top surface;
- a second portion extending away from the first portion, the second portion adapted to at least partially abut the top surface of the raised portion;
- a third portion extending away from the second portion, the third portion adapted to at least partially abut the first side surface and the second side surface of the raised portion respectively;
- and
- a fourth portion extending away from the third portion, the fourth portion adapted to at least partially abut the outer surface;
- and
- a tooth segment provided on the top surface of each of the at least one first segment and the at least one second segment respectively, wherein each of the at least one first segment and the at least one second segment is adapted to receive at least a portion of a track of the electric rope shovel thereon.
