Abstract

A device for vibration-free mounting of a drive motor on or in a stand of a surgical microscope is described. The drive motor is embodied as a stepper motor ( 1 ) and is joined to the stand via a receiving flange ( 2 ). An elastomeric mount ( 3 ) is arranged between the stepper motor ( 1 ) and the receiving flange ( 2 ) in order to damp pulses and/or vibrations that occur.

Claims (8)

1. A device comprising:

a receiving flange;

a stepper motor secured on the receiving flange, wherein the stepper motor includes a securing plate facing the receiving flange;

at least one elastomeric mount arranged between the securing plate of the stepper motor and the receiving flange to damp vibrations and pulses resulting from operation of the stepper motor, and

a screw connection between the stepper motor and the receiving flange to prevent shear detachment of the stepper motor from the receiving flange, wherein the screw connection includes a screw fixed at one end to the securing plate and arranged to extend through an orifice in the elastomeric mount and through an orifice in the receiving flange, a nut mounted on an opposite end of the screw, and an O-ring mounted on the screw between the nut and the receiving flange.

2. The device according to claim 1 , wherein the at least one elastomeric mount is joined to the stepper motor by a first layer of adhesive and is joined to the receiving flange by a second layer of adhesive.

3. The device according to claim 1 , wherein the stepper motor includes a rotating spindle.

4. The device according to claim 1 , wherein the elastomeric mount has a minimum thickness of 4 mm.
