  • Combination drill motor with measurement-while-drilling electronic sensor assembly
    Patent number: 5817937
    Abstract: A combination drill motor with measurement-while-drilling sensor apparatus includes a rotor within a stator. The rotor rotates and gyrates in response to fluid flow through the stator. An outer housing assembly having a bearing housing and a sensor housing is connected to the stator. A drive shaft is concentrically located within the bearing housing. A bearing assembly is positioned between the bearing housing and the drive shaft. A sensor cartridge assembly having a longitudinal throughbore is suspended within the sensor housing. A power transmission assembly connects the rotor to the drive shaft. The power transmission assembly includes a shaft assembly extending through the longitudinal throughbore in the sensor cartridge assembly. An annular space is formed in the longitudinal throughbore between the sensor cartridge assembly and the shaft assembly and the fluid flows through the annular space.
