THE OPERATION MANNER OF THE SYSTEM ACCORDING TO THE INVENTION IS AS FOLLOWS

(12) It is related to an innovative nut mechanism which performs different features compared to similar ones as a result of operations carried out on nut thread (1.1) that is formed by following a helix line having an exact line and space (15) which is of a thread profile of the nut shaft (1.14) and rotating 360 degrees of single cycle on the profile and on the nut shaft (1.14) with this thread profile, as seen in the part in the figure (FIG. 1).

(13) When we look at the surface of this formed thread (1) from the top (FIG. 4), we see that mounting surfaces (1.7), (1.8) have been formed in the initial and end parts of the nut thread (1.1). The main goal of these surfaces is to obtain a smooth surface on which the feedback apparatus (3), (4), (5), (6) can be mounted. Besides, these formed surfaces (1.7), (1.8), when looked at from the top (FIG. 4), it is recorded making an exact x angle to the interception line of initial and end parts of nut thread profile (1.1) and being a tangent to the line of the inner ball channel (1.2) closer to the center.

(14) These surfaces (1.7), (1.8) provide a ball cycle (10) in the inner ball channel (1.2) supported during rotation except for the mounting of feedback apparatus (3), (4) and the pins (5),(6) supporting the rotation of balls.

(15) Each ball cycle is supported from 4 points (3.3), (3.4), (3.5), (5.2) during feedback (FIG. 5).

(16) The formation of surfaces which will support balls during feedback operation that two screw cycles (10), (11) operating separately on the screw thread carrier surface (14.1), (14.2) in screw line and space (15) are regained to the system is as follows (FIG. 5).

(17) The balls in the inner ball cycle (10) use the feedback part mounting surface (1.8), pinrotation surface (5.3), pinsurface (5.1), and rotation support surface (3.5) (FIG. 5).

(18) The balls in the outer ball cycle (11) use the pin surface (5.2), feedback part rotation surface (3.4) and feedback part support surface (3.5) (FIG. 5).

(19) The formation of these surfaces in the present invention is due to the geometry formed by the mounted parts (FIG. 6), not by a single part.

(20) The channels (1.2), (1.3), (1.4), (1.5) opening to the screw thread are divided into two types. These can be divided as carrier channels (1.2), (1.3) and feedback channels (1.4), (1.5).

(21) The balls finished in carrier channels (1.2), (1.3) are transferred to feedback channels (1.4), (1.5) by means of the feeding part (3) and regained to the system by means of the other feedback part (4).

(22) The system finishes this closed cycle ball cycle (10), (11) without completing a single tour (FIG. 2).

(23) The reason for that is the designed nut part (1) establishes relationship with the screw thread or a single carrier surface (14.1) of the spring (14) and forms a mounting space (1.13) providing to apply pressure symmetrically of a second similar part (2) (FIG. 9).

(24) In order to provide the similar second part to apply pressure symmetrically (FIG. 9), a mounting space (1.13) following the helix line, which forms the nut thread on the nut shaft (1.14) on the nut thread (1.1), is opened.

(25) Due to the other parts (3), (4), (5), (6) which provide for the ball cycle being present in a 360 degree motion and in line and space (15) (FIG. 2), mounting spaces can be opened (1.13) on the nut part (1) and thus the similar two parts can be mounted together in desired sensitivity (FIG. 9).

(26) As a result of mounting similar two parts (1), (2) being mounted to a screw shaft or spring (14), two feedback regions are formed (12), (13), (FIG. 8) which operate in the same line and space (15) and in the reverse directions that cannot be seen in any similar mechanisms.

(27) When we look further to these feedback regions (12), (13) (FIG. 8), we see that each ball cycle (11) establishes a relationship with the carrier surface (14.1), (14.2) in 2 different directions of screw shaft or spring (14) in the same line and space (15) independently (FIG. 8).

(28) Due to feeding back without making use of the screw thread or carrier surfaces (14.1), (14.2) of the spring (14), choosing the screw profile as square or trapezoidal and the ball cycles (10), (11) which operate on these surfaces carry out feedback in line and space (15), the use of 2 ball cycles (10), (11) on the same surface is provided, and preloading (FIG. 9) can be applied to these ball cycles. By this means, higher efficiency and sensitivity can be obtained from the surface of the screw or the spring (14.1), (14.2) formed because of this single rotation.

(29) The points of the present invention that can be enhanced

(30) Since the system in the present invention operates the ball cycles of the ball cycles comprised in a different manner from the similar, the use of bobbins instead of balls in the system can be provided by means of the thread geometry and the ball channel number can be increased in the present system.
