TATTOO MACHINE AND SELF-ALIGNING SUPPORT OF TATTOO MACHINE MOTOR SHAFT Russian patent published in 2018 - IPC A61M37/00 

FIELD: cosmetology; instrument making.

SUBSTANCE: inventions relate to the equipment for carrying out cosmetic procedures and can be used to apply artistic tattoos and permanent makeup to the human body. Tattoo machine contains guide bushing that is installed inside curved body coaxially with the socket of painting module, and leading link in the form of rotor. Axis of the guide bushing is located at an angle of 3 to 25 degrees to the rotor axis. Support hinge is made with three degrees of freedom. Guide groove is an integral part of the rotor. Pusher comprises guide member forming a kinematic pair with five degrees of freedom with the rotor guide groove. Outer end of the pusher enters the guide bushing, forming with it a kinematic pair with four degrees of freedom. Support hinge and guide groove are rotatably mounted together with the rotor relative to the housing. Pusher performs a complex spatial motion in which the support hinge communicates the pusher reciprocating component of the motion, and the contact of the pusher guide component with the rotor guide groove ensures alignment of the rotational component of the pusher's motion component with the rotor rotation. Self-aligning motor shaft support is provided between the motor shaft and the housing of tattoo machine with the possibility to transfer axial and radial loads to the housing and comprises bushing, elastic ring and at least two rolling bearings. Bushing is made with groove and chamfers on the outer surface. Rolling bearings are installed in the bushing. Elastic ring is installed in the groove with the possibility to eliminate spontaneous rotation of the self-aligning support relative to the housing of tattoo machine.

EFFECT: as a result, the housing vibration is reduced and the reliability of tattoo machine is increased due to radical reduction in the transmission friction, design simplicity and reliability of the motor shaft mounting assembly.
