Abstract
A housing for a mud motor is disclosed. The housing comprises a female member comprising a female mating section and a male member comprising a male mating section and a housing section. The male mating section is matingly received within the female mating section. The collar is positioned on the housing section. The collar is made up of a framework with a plurality of discrete bodies spaced about the framework and a portion of each of the discrete bodies protrudes above the framework.
Claims49
A housing for a downhole component, the housing comprising a collar having a pair of longitudinal ends spaced apart from each other and a bore therethrough, the collar comprising:
- (a) a framework;
- and
- (b) a plurality of discrete bodies spaced about the framework, a portion of each of the plurality of discrete bodies protruding above a surface of the framework;
- wherein the framework and the plurality of discrete bodies extend between the longitudinal ends of the collar.
A housing for a mud motor, the housing comprising:
- (a) a female member having a female mating section;
- (b) a male member having a male mating section and a housing section, the male mating section being inserted into the female mating section and coupled to the female mating section whereby the male and female mating sections overlap;
- and
- (c) a collar as claimed in any one of claims 1 to 18 located between the overlapping male and female mating sections and positioned on the housing section.
A housing for a mud motor, the housing comprising:
- a first end comprising a first coupling and a second end comprising a second coupling, the first and second ends attached to one another;
- a reduced-diameter section extending between and connecting the first and second ends;
- and
- a collar extending circumferentially around and along the reduced-diameter section, the collar comprising:
- a plurality of metal rings, the plurality of metal rings being axially spaced apart from one another by discrete bodies disposed between adjacent ones of the plurality of rings.
A method for making a housing for a mud motor, the method comprising:
- placing a collar around a tubular housing portion;
- coupling the housing portion to at least one other part to yield an assembly wherein the collar is located between first and second shoulders;
- and
- axially compressing the collar.
Apparatus comprising any new and inventive feature, combination of features, or sub-combination of features as described herein.
Methods comprising any new and inventive step, act, combination of steps and/or acts, or sub-combinations of steps and/or acts as described herein.
