Lock nut device
First Claim
1. Lock nut arrangement comprising, firstly, a threaded nut element, the threads of which are disposed to engage threads on a second element, said nut element having a profile portion for engagement with a tool and, secondly, a locking element adapted to be non-rotatably coupled to the nut element, said locking element also adapted to be non-rotatably coupled to another element (4), said locking element being at least partially resilient (31;
- 61;
71) with a portion (32;
68;
78) extending over the tool engaging profile portion (23;
63;
73) of the nut element (22;
61;
71), and said locking element being so formed so that it is forced out of engagement with said other element (4) or with the nut element (61;
73) when a tool is moved into engagement with the profile engagement portion (23;
63;
73) of the nut element.

Abstract
A lock nut device consists of a lock nut (22) and a lock spring (31). The spring is bent into an U-shape and extends in a axial plane over the nut. It has spring legs (32) lying in grooves (25) in the nut and has end portions formed for engagement with the profile portion (16) on a non-rotatable element (4). In the engagement position, the legs are at such a distance from the nut surface that, with the aid of a socket forced over the nut, they can be pressed towards the nut surface, thus moving the end portion from the engagement position.

9. Lock nut device for axially fixing an internally splined (16) propeller hub (1) on an externally splined propeller shaft (8), comprising:
- an internally threaded nut (22) disposed to be screwed onto a threaded portion (11) of a propeller shaft, and a locking element (31) with means for fixing the nut against rotation on the shaft, said locking element being a U-shaped bent element (31) which extends in an axial plane over the nut (22) and having spring legs (32), which lie in grooves (25) in the nut to prevent rotation of the locking element relative to the nut, said legs having end portions (33), which are formed to engage the internal splines (16) of the propeller hub (1), said legs, in the engagement position of the end portions, lying at such a distance from the nut that they, with the aid of a socket which is adapted to be slipped over the nut, can be pressed against the nut surface so that the end portions are moved from the engagement position.
