Shaft locking mechanism

Abstract

A retrievable shaft locking mechanism for axial and rotational locking on smooth round shafts with a lever providing tensioning of the clamping ring and vectorially supporting a clamping action through a horizontal dowel pin.

Claims

1. A shaft locking mechanism for variable diameters of said shaft comprising: a housing having an adjustable inner diameter adapted to secure materials on said shaft while rotating; a leverage bar pivotally connected to said housing adapted for clamping said housing to said shaft; and adjustable length dowel pin connected to said leverage bar and said housing and adapted to change said inner diameter of said housing as desired; and an adjustable set screw adapted to provide contact and securing said shaft in said inner diameter of said housing.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

(8) Referring to the illustrations, drawings, and pictures, reference character 10 generally designates a new and improved shaft locking mechanism and method of using same constructed in accordance with the present invention. Invention 10 is generally used for securing a reel on a rotating steal round bar with a generally smooth surface such as but not limited to supply rollers and spool machines. It is contemplated that invention 10 may be utilized for other applications.

(9) Shaft locking mechanism 10 may comprise a housing 20 and a leverage bar 25 and or clamp and or clamping ring 30 wherein said clamp 30 is pivotally connected to housing 20 via pin 40. Clamp 30 provides axial locking forces on a shaft 50 when engaged and or locked such that clamp 30 is pushed to a down position 60 generally against housing 20. Clamp 30 is unlocked and or disengaged when clamp 30 is pushed away from housing 20 to open position 70.

(10) Housing 20 may have threaded aperture 80 for receiving extended tip set screw 90 for adjusting an inner diameter 100 of housing 20. Screw 110 and washer 120 may be utilized. Housing 20 may include pin dowel 130 and pin slotted spring 140.

(11) Shaft locking mechanism contemplates a housing, a freely supported clamping ring adapted to surround a shaft and located inside the housing with pretensioning by a clamp force in any chamber (whatever the shape, in this case oval), changeable in an axial direction.

(12) Horizontally trapped dowel pin provided on the clamping ring and contacting surfaces, which limit the chamber in contact points, a locking unit and a clamping unit provided with an adjustable locking thread and arranged so that axial locking forces are transmitted through the locking unit and the locking thread of the clamping unit and through the horizontal dowel pin for form-locking connection between the clamping ring and the shaft in the region of self-locking, and a lever providing tensioning of the clamping ring and vectorially supporting a clamping action through the horizontal dowel pin.

(13) The current invention 10 therefor contemplates a shaft locking mechanism for variable diameters of said shaft comprising: a housing having an adjustable inner diameter adapted to secure materials on said shaft while rotating a leverage bar pivotally connected to said housing for clamping said housing to said shaft; and adjustable length dowel pin connected to said leverage bar and said housing and adapted to change said inner diameter of said housing as desired.

(14) Changes may be made in the combinations, operations, and arrangements of the various parts and elements described herein without departing from the spirit and scope of the invention. Furthermore, names, titles, headings, and general division of the aforementioned are provided for convenience and should, therefore, not be considered limiting.
