Abstract: Pinion formed by two joinable parts mountable on a shaft includes a substantially semi-circular first portion of the pinion; a substantially semi-circular second portion of the pinion; the first portion has a first joining surface and a first portion of a hole concentric with the pinion; the second portion has a second joining surface and a second portion of a hole concentric with the pinion; the first joining surface is adapted to be joined to the second joining surface by means of connection means; characterized in that the connection means includes a first bushing and a second bushing; the first bushing is fixed onto said first portion and protrudes from the first joining surface; said second bushing is fixed onto the first or second portion and protrudes from the first or second joining surface.

Abstract: A module for forming a conveyor, particularly a band conveyor, presenting a plurality of modules connected together, each module including: an upper surface, a lower surface, conventional elements for removably connecting the modules together to form the conveyor, and connection element for removably connecting additional members, particularly a thrust bar, to the upper surface; in which the connection element includes, on the exposed face of the upper surface of the module, at least one predefined identification mark, the module presenting, below the upper surface in a position corresponding with the at least one predefined mark, at least one connection element extending from and closed by the upper surface and provided with, or in which there can be provided, a seat or hole adapted to cooperate with means, to removably connect the additional member to the upper surface of the module.

Abstract: Module, for conveyor presenting connected modules, having upper and lower surfaces, two lateral walls, front and opposing rear walls and, projecting from front wall and rear wall module connecting elements. Connection elements each comb shaped, so one module's elements insertable between next or preceding module elements, and having through holes mutually coaxial for receiving transverse pin for removably connecting at least two modules. Each module has element blocking pin longitudinal movements including locking element removably insertable into seat in module. Seat communicates with through holes and extends from module upper to lower surface. In positions corresponding with each surface an aperture for inserting or removing locking element into or from seat. Locking element elastically deformable portion, only if deformed, enabling inserting and snap-retaining locking element in seat, preventing pin longitudinal movements.
