Title:
ROTATION SUPPORT STRUCTURE OF ELECTRIC CYLINDER
Document Type and Number:
Japanese Patent JP2023133789
Kind Code:
A
Abstract:
To obtain a rotation support structure of an electric cylinder which does not cause interference between members while enhancing a degree of freedom of a component constitution, and is compact in a size.SOLUTION: A rotation support structure of an electric cylinder D comprises a cylindrical housing H, a motor M having an output shaft A1 and a reduction mechanism K connected to the output shaft A1. The reduction mechanism K comprises a gear unit U having a pivot part 2 having a first gear G1 which is driven-rotated to the output shaft A1 at one side, and attached with an outer member 4 and balls 1 which are co-rotated together with the first gear G1 at the other side, and oppose an internal peripheral face of the housing H, and an annular second gear G2 fixed to the internal peripheral face of the housing H, and screwed with the first gear G1. The second gear G2 and the pivot part 2 are arranged in an extension direction of an axial core X while separating from each other in a view in a direction orthogonal to the axial core X of the output shaft A1, and the outer member 4 and the first gear G1 are arranged in a state that they are separated from each other in a view in a direction along the axial core X.SELECTED DRAWING: Figure 1
