  • the shaft may be actuated by other means, such as manually or electromechanically as well as by air power as aforementioned.
  • the shaft of the tool may be coupled to a hand-held power drill, for example.
  • my invention has been devised with the object of overcoming or alleviating some or all of the disadvantages currently experienced, and it has for its principal object the provision of a nut runner tool which may be easily placed operatively and used in many instances in which difficulty would have been encountered in the past, while at the same time being of improved efficiency in operation.
  • Another object of the invention is to provide such improvements in a nut runner tool as will lead to its being able to be designed in a more compact form than previously, available, particularly so far as the nut- engagement assembly is concerned.
  • Other objects and advantages of the invention will be apparent from the descriptions set out later herein.
  • the invention resides broadly, according to one aspect, in a nut runner tool of the type having a rotatable shaft adapted to be rotated from one of its ends and having at its other end a nut-engagement assembly, characterized in that the nut-engagement assembly includes a first gear rotated by the shaft and a second gear rotated by said first gear and having an aperture or recess to accommodate a nut to be rotated, the second gear being offset from the shaft to facilitate visually locating same relative to said nut.
  • a continuous aperture be provided after the manner of a ring- spanner so that engagement of the nut by the second gear can be viewed in the direction along the shaft towards said nut.
  • a nut runner tool including an elongate casing; actuator connector means at one end of the casing; a nut-engagement assembly at the other end of the casing, and a drive shaft mounted rotatably in the casing and extending from end to end thereof, the shaft end at said one end of the casing being adapted to be connected drivably when said actuator connector means is coupled to a source of power for effecting rotation
  • said nut-engagement assembly including a gear housing in which two gears are mounted rotatably in meshing relationship, one of said two gears being a first or driving gear rotatable by the drive shaft at said other end of the casing, the other or second gear being a driven gear having on its axis of rotation an aperture shaped to accommodate a nut to be rotated therewith when said driven gear is rotated by the driving gear upon rotation of the shaft, the second or driven gear being offset from the shaft to facilitate visually locating same relative to said nut, said aperture being axially continuous to enable engagement of
  • the shaft may consist of two longitudinal sections interconnected end-to-end in unaligned relationship by a universal joint, the sections being rotatable in unison in respective portions of the elongate casing which is correspondingly bent adjacent the universal joint.
  • the second gear be closely rotatable in a bore of the gear housing and restrained against axial movement in the bore by apertured cover means. In this way, the components around the second gear can be designed so that a very compact assembly is achieved.
  • the nut runner tools may use a source of power which is manually operated, or alternatively air driven, or suitably electromechanically operated.
  • the tool is available with an adaptor housing at the drivable end of the shaft so that it can be coupled to a hand-held, trigger operated, electric drill commercially obtainable as a rechargeable, cordless, electric drill mechanism.

  • Fig. 1 In use, the parts are assembled as described to form the complete tool shown in Fig. 1, and this may be used as apparent from Figs. 5 and 6 which show the crankcase 4 ' 2 " and engine cylinders 43, each containing a piston, one of which is shown at 44 in Fig. 6. Nuts 45 are used on numerous threaded fasteners 46, locknuts 47 also being shown. Fig. 6 shows a nut being removed, and it will be noted that the nut-engagement assembly 13 is very compact for use in restricted ⁇ areas.

Abstract

On présente un outil de serrage d'écrous du type à arbre rotatif (10) adapté pour être entraîné par rotation à l'une de ses extrémités (11) et possédant à l'autre extrémité (12) un dispositif destiné à saisir les écrous (13). Ce montage (13) comprend un premier engrenage (33) entraîné en rotation par l'arbre (10), et un deuxième engrenage (34) entraîné en rotation par le premier engrenage (33) et possédant une ouverture ou un évidement (39) dans lequel vient se loger l'écrou devant être entraîné en rotation, le deuxième engrenage (34) étant décalé par rapport à l'arbre (10) pour faciliter la localisation visuelle de celui-ci par rapport audit écrou. L'ouverture (39) est de préférence continue comme pour une clé à ÷il, de telle sorte que la saisie de l'écrou par le deuxième engrenage (34) soit visible dans le sens de la longueur de l'arbre (10). Ce dernier est de préférence rotatif à l'intérieur d'une gaine (19) se prolongeant depuis le montage de saisie d'écrous (13) vers un boîtier adaptateur (27) de telle sorte que l'arbre (10) puisse être relié par entraînement mais de façon amovible à une source d'énergie motrice telle qu'une perceuse à main (21).
