Abstract

The utility model relates to a graded crushing machine specifically is a big belt pulley connection device of graded crushing machine. Including big belt pulley and fluted roller main shaft, be flexible connection structure between big belt pulley and the fluted roller main shaft, the driven plate is equipped with on the big belt pulley, the initiative dish is equipped with on the fluted roller main shaft, be quiet draw bail between fluted roller main shaft and the initiative dish, the initiative dish is connected with the driven plate through safe round pin. The utility model discloses both normal operation torques of transferable again can be when the breaker transships reaches and cuts off being connected between moment of torsion, the big belt pulley of disconnection and the fluted roller main shaft through cutting safe round pin to play the safety protection effect to big belt pulley.

Description

Sizing Crusher big belt pulley connection set

Technical field

The utility model relates to Sizing Crusher, specifically a kind of Sizing Crusher big belt pulley connection set.

Background technique

Big belt pulley is the parts of the important transferring power of Sizing Crusher, the driving force of motor is delivered to big belt pulley by belt, belt pulley drives discaling roll main shaft to rotate again, fragmentation is carried out to material, at present, by Flat dey joint transmitting torque between major part Sizing Crusher big belt pulley and main shaft, this connecting mode easily causes big belt pulley to damage under the effect of heavy load, large impact, and the equipment that affects runs well.

Model utility content

The utility model is intended to solve the problem, thus provides a kind of Sizing Crusher big belt pulley connection set shielded to big belt pulley.

The utility model solves described problem, and the technological scheme of employing is:

A kind of Sizing Crusher big belt pulley connection set, comprise big belt pulley and discaling roll main shaft, it is movable connection structure between big belt pulley and discaling roll main shaft, big belt pulley is equipped with driven disc, discaling roll main shaft is equipped with driving disc, be quiet connecting structure between discaling roll main shaft and driving disc, driving disc is connected with driven disc by safety pin.

Adopt the utility model of technique scheme, compared with prior art, its outstanding feature is:

Both can transmit normal Operating torque, and can reach and cut off moment of torsion by cutting off safety pin, disconnect connection between big belt pulley and discaling roll main shaft when disintegrator transships again, thus safety protection effect is played to big belt pulley.

As preferably, the utility model further technological scheme is:

Driven disc is arranged on the discaling roll main shaft of big belt pulley side, and the discaling roll main shaft of big belt pulley opposite side is provided with clutch wheel, and big belt pulley is connected with clutch wheel and driven disc respectively by high-strength bolt.

Big belt pulley is connected with discaling roll main shaft by axle sleeve.

Discaling roll main shaft is provided with flat bit architecture, the axis hole of driving disc is provided with the flat hole structure coordinated with flat bit architecture.

The axle head of the discaling roll main shaft of the relative driven disc opposite side of driving disc is provided with shaft end ring.

Accompanying drawing explanation

Fig. 1 is the utility model example structure schematic diagram;

Fig. 2 is the structural representation of the utility model embodiment driving disc;

In figure: high-strength bolt 1, axle sleeve 2, clutch wheel 3, flat bit architecture 4, big belt pulley 5, driven disc 6, driving disc 7, shaft end ring 8, discaling roll main shaft 9, safety pin 10, axis hole 11, flat hole structure 12.

Embodiment:

Below in conjunction with embodiment, the utility model is described in further detail, and object is only to understand the utility model content better, and therefore, the cited case does not limit protection domain of the present utility model.

See Fig. 1, Fig. 2, big belt pulley 5 is linked together by axle sleeve 2 and discaling roll main shaft 9, the discaling roll main shaft 9 of big belt pulley 5 both sides is separately installed with clutch wheel 3 and driven disc 6, clutch wheel 3, big belt pulley 5 and driven disc 6 are linked together by high-strength bolt 1, discaling roll main shaft 9 on the right side of driven disc 6 is provided with flat bit architecture 4, driving disc 7 is arranged on the flat position 4 of discaling roll main shaft 9, the axis hole 11 of driving disc 7 is provided with the flat hole structure 12 coordinated with flat bit architecture 4, driving disc 7 is connected with driven disc 6 transmission realizing moment of torsion by safety pin 10, driving disc 7 is fixed by the shaft end ring 8 of axle head on the right side of discaling roll main shaft 9.

Can smooth transfer moment of torsion in disintegrator course of normal operation, when apparatus overload, reach and cut off moment of torsion by cutting off safety pin 10, disconnect connection between big belt pulley 5 and discaling roll main shaft 9, thus play the effect of proterctive equipment.

The foregoing is only the better feasible embodiment of the utility model, not thereby limit to interest field of the present utility model, the equivalence change that all utilization the utility model specifications and accompanying drawing content thereof are done, be all contained within interest field of the present utility model.
