Abstract
A mud motor stator or a pump comprising of a tubular outer portion; a number of lobes extending radially inwardly from the tubular outer portion, at least one of which comprises a skeletal structure and method for producing a mud motor stator or a pump comprising of placing material and bonding the material together in a pattern dictated by the design shape of the stator or pump.
Claims14
A method for producing a stator comprising:
- placing material and bonding the material together in a pattern dictated by the design shape of the stator the shape including a number of lobes, at least one of which having a skeletal structure, at least one of the number of lobes having a load side and a seal side, the seal side being less supported by the skeletal structure than the load side.
A method for producing a stator comprising:
- creating a computer model of a stator having a number of lobes, at least one of which comprises a skeletal structure, at least one of the number of lobes having a load side and a seal side, the seal side being less supported by the skeletal structure than the load side;
- loading the model into an additive manufacturing apparatus;
- operating the additive manufacturing apparatus to produce a physical replica of the model.
