Description
The pin joint consists of two steel hubs to be fitted respectively on the driving shaft and on the driven shaft. The two hubs have two drilled crowns in which conical holes alternate with cylindrical holes of variable number and size depending on the size (size) of the joint. The motion transmission between the two hubs takes place through steel pins consisting of a conical part with a threaded stem and a cylindrical part with a hexagonal head. A rubber plug (gommolo) with an external barrel profile and internal cylindrical hole is fixed to the cylindrical part; the pins, complete with rubber, constitute the typical elements of the joint called pegs and are fixed alternately on the two hubs in the conical holes with locking nuts. The hubs, complete with pegs,
