Abstract

The invention discloses a distribution gear case of a homodromous tapered double-screw extruder. The distribution gear case comprises a case body, a rear cover plate, a connecting sleeve, a flange, a locknut, a transmission long shaft, a transmission short shaft and an intermediate shaft; one side of the case body is connected with the connecting sleeve through the flange, and the other side of the connecting sleeve is connected with the locknut; the transmission long shaft is installed in the case body; the case body is connected with the rear cover plate; and the transmission long shaft is provided with a first small taper gear, the transmission short shaft is provided with a second small taper gear, the intermediate shaft is provided with a large taper gear, the large taper gear is meshed with the first small taper gear and the second small taper gear, and a gap is left between the addendum circle of the first small taper gear and the addendum circle of the second small taper gear. The distribution gear case disclosed by the invention is particularly suitable for changing an incongruous tapered double-screw extruder into the homodromous tapered double-screw extruder, and distribution gear case parts only need to be changed and the other parts of the extruder are reserved during the changing.

Description

technical field [0001] The invention relates to the field of rubber and plastic machinery, more specifically, the invention relates to a transmission mechanism, in particular to a distributing gearbox for a co-rotating conical twin-screw extruder. Background technique [0002] Compared with the counter-rotating conical twin-screw extruder, the co-rotating conical twin-screw extruder has excellent mixing performance, energy saving and high productivity, and has begun to be used in the filling, blending and modification of rubber, plastic and engineering resins. devolatilization of chlorinated polypropylene and superabsorbent resin; degradable masterbatch, polyamide polycondensation, polyurethane polyaddition reaction extrusion; carbon powder, magnetic powder granulation, cable insulation material, sheath Preparation of low-smoke and low-halogen flame-retardant PVC cable materials and various silane cross-linking materials. For an extruder, the distribution gearbox is one of ...
