Abstract:
1. A device comprising: a housing; a first assembly including a first worm shaft and a first worm wheel, wherein the first worm shaft is coupled to the housing through bearings and first and second independently adjustable bearing supports attached to corresponding first and second recesses in first opposing sides of the housing; a tilt motor mounted external to one of the first opposing sides of the housing, the tilt motor having a tilt motor shaft received by a first end of the first worm shaft; a tilt shaft coupled to the first worm wheel, the tilt shaft supported by tilt shaft bearings directly received by the housing; a second assembly including a second worm shaft and a second worm wheel, wherein the second worm shaft is coupled to the housing through bearings and third and fourth independently adjustable bearing supports attached to corresponding third and fourth recesses in second opposing sides of the housing; a pan motor mounted external to the one of the second opposing sides of the housing, the pan motor having a pan motor shaft received by a first end of the second worm shaft; a pan shaft coupled to the second worm wheel, the pan shaft supported by pan shaft bearings directly received by the housing; and a base receiving the pan shaft such that rotation of the pan shaft by the second worm wheel rotates the housing with respect to the base, wherein each bearing support comprises an adjustment mechanism configured to adjust a location of the bearing support within a corresponding recess to provide independent cross axial position adjustment in two dimensions of one end of the first or second worm shaft, wherein the adjustment mechanism comprises a plurality of screws threaded into the housing in the corresponding recess and a corresponding plurality of through holes in each bearing wherein diameters of the plurality of through holes are larger than corresponding diameters of threaded shafts of the plurality of screws to allow two dimensions of adjustment of each bearing support location relative to the corresponding recess in the housing to provide for finely adjusting positions of the first and second worm shafts within the device.
