Abstract
The down hole motor is a self-contained radial drive unit that is driven by a linear input, which can be supplied from various sources. As linear motion is applied to the input of the tool, drive pins on a drive shaft follow a helical path, converting the linear motion into radial motion at the attached mandrel end. This may then be utilized in various activities such as drilling, boring and obstruction removal. This tool may also be used in conjunction with jarring mechanisms in order to create an impact drilling device, or a percussion motor.
Claims33
A down hole motor assembly comprising:
- a. an outer mandrel,
- b. a reciprocating drive shaft shaped to fit within said outer mandrel having helical grooves shaped to receive drive pins,
- c. an upper rotating mandrel operatively engaged to said reciprocating drive shaft to permit transfer of motion,
- d. an upper gear shaped to fit within said outer mandrel, and operatively engaged to said upper rotating mandrel to maintain mechanical communication,
- e. a lower gear shaped to fit within said outer mandrel and shaped to operatively engage said upper gear to provide mechanical communication, and
- f. a lower rotating mandrel operatively engaged with said lower gear to maintain mechanical communication.
