ABSTRACT:
A compact torque absorber is provided to absorb the reaction torque of a submergible pump upon discharge tubing which supports the pump. The torque absorber comprises inner and outer tubular members having outwardly directed and inwardly directed interdigitated projections, respectively, which are spaced apart circumferentially for receiving torque absorbing elements therebetween, the tubular members being relatively rotatable to a limited extent. The outer member has an internal annular collar at one end through which the inner member extends and which supports a fluid seal. The projections of the outer member extend upwardly from the collar and carry a thrust ring upon their upper ends. An external annular collar of the inner member provides an annular shoulder spaced from the thrust ring. Ball bearings are provided between the thrust ring and the shoulder. Additional seals at the external collar of the inner member isolate the thrust bearing from the pumped fluid. A retainer ring prevents axial separation of the inner and outer members.
