Abstract:
A motor base for use in vibratory apparatus having an eccentric drive mounted on an exciter, the eccentric drive including a driven shaft rotatably mounted on the exciter and disposed along a driven shaft axis, a motor having a motor shaft disposed along a motor shaft axis, the motor shaft axis being spaced from and parallel to the driven shaft axis, and a drive belt operably coupled to the driven shaft and the motor shaft, the motor base comprising:a rigid support journally supported for movement relative to the driven shaft axis, the rigid support having a free end adapted to carry the motor, the rigid support moving in response to movement of the exciter; anda resilient support having a first end attached to the free end of the rigid support and a fixed second end, the resilient support being sized to suspend the motor and rigid support and moving in response to movement of the exciter acting on the rigid support;wherein the motor base maintains a constant center distance between the driven shaft axis and the motor shaft axis as the rigid support and the resilient support move in response to movement of the exciter.
