Patent ID: 8227949

Claim:
A linear actuator ( 1 ) comprising a stator ( 3 ) placed within a cartridge-like casing ( 2 ), a bearing ring ( 4 ), in assembled condition being located behind the stator ( 3 ), a bearing seat for mounting a rotor ( 5 ) with an antifriction bearing ( 6 ), a spindle ( 7 ) which on a drive side ( 7 . 1 ) thereof together with the rotor ( 5 ) is established as motion transformer to transform the rotary motion into a translatory motion and a flange ( 9 ) which closes the casing ( 2 ) on an output side ( 8 ) of the linear actuator ( 1 ), the flange ( 9 ) being equipped with an anti-rotation locking device for the spindle output side ( 7 . 2 ) which penetrates the flange ( 9 ), wherein the cartridge-like casing ( 2 ) is provided with several formed bending tongues ( 10 . 1 , 10 . 2 ), and wherein, in assembled condition, a first bending tongue ( 10 . 1 ) engages with groove-like recesses ( 11 ) of the bearing ring ( 4 ) of the antifriction bearing ( 6 ) and a second bending tongue ( 10 . 2 ) engages with groove-like recess ( 11 ) of the flange ( 9 ) so that all components ( 3 , 4 , 5 , 7 and 9 ) placed in the casing ( 2 ) are tensioned against each other without further connection techniques being required.
