ABSTRACT:
A worm gear transmission having a worm wheel which is journalled in a housing and a worm rotatably journalled at one end in a bearing pivotably connected to the housing, and at the other end in a second bearing engaged by an adjustable pre-load spring which presses the worm towards the wheel. The pivotably arranged bearing is also axially displaceable and is coupled to a first member which cooperates with a second member, rigidly coupled to the housing at least in the axial direction, such that, upon axial displacement of the pivoted bearing by torque loading, one of the members undergoes transverse displacement which is coupled to vary the pre-load force in the spring.
