Abstract
An extendable section, for attachment to a fixed screed, may include a rotatable shaft, and a power receiving component attached to the rotatable shaft. The power receiving component may receive power generated during rotation of a drive shaft, and generate torque and speed for rotating the rotatable shaft. Increasing the driving rotational speed of the drive shaft may increase a driven rotational speed of the rotatable shaft, and decreasing the driving rotational speed of the drive shaft may decrease the driven rotational speed of the rotatable shaft.
Claims20
A paving machine, comprising:
- a screed assembly including a fixed screed and an extendable section disposed proximate an end of the fixed screed, wherein:
- the fixed screed comprises:
- a first drive shaft that extends through one or more portions of the fixed screed, and
- a second drive shaft that extends through the one or more portions of the fixed screed,
- the one or more portions of the fixed screed comprise one or more of a base screed or a fixed section,
- the extendable section comprises a driven shaft,
- a power transmitting component is coupled to the first drive shaft, and
- the power transmitting component is configured to generate power in response to rotation of the first drive shaft, for actuating the driven shaft.
A screed assembly, comprising:
- a fixed screed comprising:
- a first drive shaft that extends through one or more portions of the fixed screed, and
- a second drive shaft that extends through the one or more portions of the fixed screed,
- wherein the one or more portions of the fixed screed comprise one or more of a base screed or a fixed section;
- an extendable section extending from a portion of the fixed screed,
- wherein the extendable section comprises a driven shaft;
- and
- a power transmitting component coupled to the first drive shaft,
- wherein the power transmitting component is configured to generate power during rotation of the first drive shaft, and
- wherein the power is configured to actuate the driven shaft.
An extendable section for a screed assembly, comprising:
- a rotatable shaft;
- and
- a power receiving component attached to the rotatable shaft,
- wherein the power receiving component is configured to receive power generated during rotation of a first drive shaft of a fixed screed, and generate torque and speed for rotating the rotatable shaft,
- wherein the fixed screed includes the first drive shaft and a second drive shaft,
- wherein the first drive shaft extends through one or more portions of the fixed screed,
- wherein the second drive shaft extends through the one or more portions of the fixed screed,
- wherein the one or more portions of the fixed screed include one or more of a base screed or a fixed section,
- wherein increasing a driving rotational speed of the first drive shaft increases a driven rotational speed of the rotatable shaft, and
- wherein decreasing the driving rotational speed of the first drive shaft decreases the driven rotational speed of the rotatable shaft.
