Abstract
A concrete saw can be operated at multiple speeds. The saw includes at least one neutral. A multispeed gearbox has one configuration with no more than two gear shafts. The gearbox can be mounted directly to an engine output shaft. The engine output shaft can be perpendicular to the blade drive shaft, and the blade drive shaft can be driven by belts from the gearbox.
Claims35
A concrete saw comprising:
- a motor;
- a blade support element for supporting and driving a cutting blade;
- at least one gear in a drive path between the motor and the blade support element configured to drive the blade support element for driving the blade and wherein the gear is arranged in such as way as to include a neutral position where the blade support element is not driven;
- and
- a flexible drive element in the drive path between the at least one gear and the blade support element.

A concrete saw comprising:
- a motor;
- a support for supporting and driving a cutting blade;
- a gearbox configured for driving the blade support at at least two different speeds wherein the gearbox has no more than three shafts supporting gears;
- and
- a flexible drive element between the blade support and the gearbox.
2 more elements
A concrete saw comprising:
- a motor having an output shaft wherein the output shaft is oriented parallel to a direction of travel of the saw;
- a support for a saw blade for supporting and driving a saw blade;
- a gearbox rigidly coupled to the output shaft wherein the gearbox is configured to drive the blade at at least two different speeds;
- and
- a flexible driving element between the gearbox and the blade support for driving the blade support.
2 more elements
A concrete saw for moving along a surface to be cut, the saw comprising:
- a saw frame supported for moving along the surface;
- a motor supported by the saw frame for moving along the surface and having an output element;
- a blade support element supported by the saw frame and for supporting and driving a cutting blade;
- and
- a gearbox supported for movement with the saw frame along the surface and wherein the gearbox has at least one driving gear and at least one driven gear configured to be engageable with and disengageable from the at least one driving gear and wherein the gearbox is configured to include a neutral position in which the blade support element is not driven by the motor.

A concrete saw for moving along a surface to be cut, the saw comprising:
- a saw frame supported for moving along the surface;
- a motor supported by the saw frame for moving along the surface and having an output element;
- a blade drive shaft supported by the saw frame for a cutting blade;
- a gearbox supported for movement with the saw frame along the surface and wherein the gearbox has at least one driving gear and at least one driven gear higher than the at least one driving gear and configured to be engageable with and disengageable from the at least one driving gear and wherein the gearbox is configured to include a neutral position wherein the at least one driving gear and the at least one driven gear are disengaged and in which the blade support element is not driven by the motor;
- and
- a flexible driving element in a drive path between the gearbox and the blade drive shaft.
