Embodiment Construction

[0025] exist figure 1 Above, reference numeral 100 represents the anti-rotation device of the first embodiment of the present invention.

[0026] The anti-rotation device 100 is composed of a boss portion 114 , a spline shaft 120 , and a gap adjustment mechanism 121 . Wherein, the cross-section of the sleeve part 114 is roughly circular, and a through hole 112 is formed in the axial direction; the spline shaft 120 is respectively coaxially connected with the separated first spline shaft member 116 and the second spline shaft member 118. The shaft members 116, 118 are arranged to be freely slidable along the above-mentioned hole portion 112; the gap adjustment mechanism 121 is used to adjust the circumferential gap A formed between the inner wall surface of the above-mentioned sleeve portion 114 and the outer wall surface of the spline shaft portion 120 (refer to FIG. 3).

[0027] Such as figure 2 As shown, the first splined shaft member 116 has a disc portion 126 and a sh...

Abstract

A rotation stop device comprising a mechanism (121) for regulating a circumferential clearance (A) between an inner surface of a boss (114) and an outer surface of a spline shaft (120) by turning two-split first and second spline shaft members (116, 118) in the mutually opposite directions on the axes thereof.

Description

technical field [0001] The present invention relates to an anti-rotation device capable of preventing rotation of the spline shaft in the circumferential direction by, for example, combining the spline shaft with the bore of a bushing, and an electric actuator with anti-rotation function. Background technique [0002] From the prior art, for example, a spline used as a circumferential stop of the shaft member is used. Such as Figure 23 As shown, this spline 1 has a spline shaft 4 and a bushing 6 . Among them, the spline shaft 4 forms a plurality of tooth portions 3a to 3h with slightly table-shaped cross-sections between the adjacent groove portions 2a to 2h at a predetermined angle along the circumferential direction of the outer peripheral surface; the sleeve 6 can slide relatively freely along the The above-mentioned spline shaft 4 is arranged in the axial direction, and forms a hole 5 corresponding to the cross-sectional shape of the spline shaft 4 perpendicular to the...
