Connecting structure for mechanical connection of a first housing with a second housing
View Patent ↗The invention relates to a connecting structure for mechanical connection of a first housing with a second housing, whereby one face of the second housing has a hollow cylindrical recess for inserting the first housing; according to the invention it is provided that (i) the hollow cylindrical recess is formed of a ring-shaped collar, and (ii) for producing a frictional connection of the first housing with a second housing, the collar has at least one tensioning element, which in radial direction with respect to the collar is in active connection with the first housing.
1. A connecting structure for mechanical connection of a first housing with a second housing, wherein one face of the second housing has a hollow cylindrical recess for inserting the first housing, characterized in that (i) the hollow cylindrical recess is formed of a ring-shaped collar, (ii) the hollow cylindrical recess exists prior to insertion of the first housing; and (iii) for producing a frictional connection of the first housing with the second housing, the collar comprises at least one tensioning element, which in radial direction with respect to the collar is in active connection with the first housing, wherein the first housing is a motor housing and the second housing is designed as a modular transmission housing in the axial direction, wherein a face side surface of the motor housing lies flush on a recess base of the hollow cylindrical recess, and wherein the tensioning element is designed as a threaded pin, wherein the first housing further comprises a radially arranged engagement groove for the threaded pin in the area of the collar.
2. The connecting structure of claim 1 , wherein the first housing further comprises a cylindrical flange, which is held by a pocket hole arranged on one face side of the second housing.
3. The connecting structure of claim 1 , further comprising wherein the transmission housing has a modular design, wherein the one face side is designed with the ring-shaped collar and a centering opening is designed as a motor flange.
4. The connecting structure of claim 3 , wherein the motor flange further comprises a drive shaft mounted in a ball bearing, which is in active connection with an output shaft guided by the cylindrical flange of the motor housing.
