Abstract: A gearbox comprising a main unit comprising a first casing and a first hollow shaft, and a secondary unit comprising a second casing and a second hollow shaft, and a drive shaft comprising a first clutch portion and a second clutch portion, which engage the first and second hollow shafts in an angularly fixed and axially sliding manner. The gearbox further including an axial retaining device comprising an axial shoulder supported in a fixed potion by an axial end on one of the first or second hollow shafts, and an external radial projection arranged in an intermediate position, and an external radial projection arranged in an intermediate position along the drive shaft between the first and second clutch portions.

Abstract: A gearbox has a main unit and a secondary unit provided with respective casings of respective gear transmissions and with respective hollow shafts connected by means of a drive shaft; the secondary unit transfers motion between two axes forming an angle of less than 180° and which can be removed after having released the drive shaft; the drive shaft is engaged in an angularly fixed and axially sliding manner to the hollow shafts and is axially locked, at least in one direction, by means of an axial retaining device, which is releasable; the axial retaining device is coupled to one of the hollow shafts, at an axial end which is facing towards the other of the hollow shafts; at least one opening may be formed between the two casings, so as to access such an axial end and release the axial retaining device.

Abstract: A gearbox (1) has a main unit (22) and a secondary unit (2) provided with respective casings (23,3) of respective gear transmissions and with respective hollow shafts (24,10) connected by means of a drive shaft (25); the secondary unit transfers motion between two axes forming an angle of less than 180° and which can be removed after having released the drive shaft (25); the drive shaft (25) is engaged in an angularly fixed and axially sliding manner to the hollow shafts and is axially locked, at least in one direction, by means of an axial retaining device (57), which is releasable; the axial retaining device (57) is coupled to one (24) of the hollow shafts, at an axial end (32) which is facing towards the other (10) of the hollow shafts; at least one opening may be formed between the two casings (23,3), so as to access such an axial end (32) and release the axial retaining device.

Abstract: The present invention relates to a method, a related system and related devices for calibrating a position of a Camera CAM for monitoring a predetermined area. The camera CAM being coupled to a remote server RS over a communications link where the remote server RS is able to receive media corresponding to said predetermined area to be monitored within an environment of said camera CAM. This media is recorded by the camera CAM and forwarded to said remote server RS over the communications link. The method comprises the step of determining camera position calibration instructions based on predefined camera position parameters defining said predetermined area to be monitored and actual camera position parameters identifying a current position of said camera as determined by a camera positioning device CPD.

Abstract: The present invention relates to a method, a related system and related devices for calibrating a position of a Camera for monitoring a predetermined area. The camera being coupled to a remote server over a communications link where the remote server is able to receive media corresponding to the predetermined area to be monitored within an environment of the camera. This media is recorded by the camera and forwarded to the remote server over the communications link. The method further comprises the step the remote server forwarding the media corresponding to the predetermined area towards a camera positioning device where the media includes a plurality of real reference markers in the predetermined area. The actual location relative to an image-framing of the camera of each real reference marker of the plurality of real reference markers is recognizing in the media forwarded.
