Abstract:
1. A driving mechanism for an apparatus such as an indexed unidirectional rotary inverting apparatus, a bi-directional curvilinear transference apparatus and a bi-directional curvilinear take-out apparatus, of a glassware forming machine, of single or multiple cavities, comprising: a carcass including a first lateral cap and a second lateral cap each at each side of the carcass; said lateral cap having a double keyway opposed 180° one another, and a support plate having a keyway which will be placed at a position depending on the apparatus in which the driving mechanism is mounted, said support plate is mounted on an apparatus support frame of the glassware forming machine by means of a semi-annular clamp; a horizontal axis supported by bearings to the lateral caps, and including a slow speed gear having a power output coupling, which is to be coupled to a power shaft for transmission of the output power of the drive mechanism; a sleeve coupled on the carcass, including a high speed extension shaft into said sleeve, having a worm gear at its lower end, gearing with the slow speed gear, which is provided with an anti-backlash mechanism, for reducing velocity and transmit power to said unidirectional inverting apparatus, said-bi-directional curvilinear transference apparatus, and said curvilinear take out apparatus; a flexible couple at the lower end of the high speed extension shaft for retiring a servomotor from a heat zone of a parison; and a rotary servomotor for rotating the high speed extension shaft, by means of the flexible couple, and supported by a frame at the lower end of the sleeve; and a flange at an intermediate position of the sleeve, to be supported on the apparatus support frame, avoiding vibration of the whole structure, so that, the double keyway of the lateral cap, allows this driving mechanism to be placed on a 180° opposed position to be mounted at the indexed unidirectional rotary inverting apparatus, the hi-directional curvilinear transference apparatus and the bi-directional curvilinear take-out apparatus, without internally disassembling the driving mechanism.
