1. A workstation support assembly comprising:
a mount assembly comprising:
a keyboard support adapted to support a keyboard; and
a display support adapted to support an electronic display over the keyboard support; and
an arm assembly configured to translate the mount assembly relative to a structure, the arm assembly including a counterbalance mechanism configured to generate a lift force to counter a weight of the mount assembly and the electronic display, the counterbalance mechanism comprising:
an energy storage member;
a cam defining a cam profile;
a cam follower coupled to the energy storage member, the cam follower adapted to move over the cam profile as the arm assembly rotates; and
an adjustment assembly coupled to the energy storage member, the adjustment assembly configured to adjust a tension of the energy storage member to adjust the lift force generated by the counterbalance mechanism, wherein the adjustment assembly comprises:
an adjustment screw;
a first gear assembly including:
a first gear shaft; and
a first bevel gear, the first gear shaft and the first bevel gear together configured to rotate about a first axis; and
a second gear assembly including:
a second gear shaft; and
a second bevel gear, the second gear shaft and the second bevel gear configured to rotate about a second axis that is perpendicular to the first axis, the second gear shaft coupled to, and coaxial with, the adjustment screw, the first bevel gear configured to cooperate with the second bevel gear to rotate the adjustment screw about the second axis to adjust the tension of the energy storage member to adjust the lift force generated by the counterbalance mechanism.
