Description

Strong double-light-roller crusher

Technical Field

The utility model relates to a powerful two smooth roller crushers belongs to breaker technical field.

Background

Powerful two light or double geared roller crushers are at broken material in-process, when the difficult broken material of bold gets into broken intracavity, the movable roll need let certain distance along the slide rail back, let difficult broken material pass through broken chamber. At this time, the coupling is required to generate certain displacement so as to adapt to the yielding of the movable roller.

The existing double-light or double-tooth roller crusher uses a flexible coupling, when the double-light or double-tooth roller crusher adopts the coupling to transmit torque, the axial tension is smaller, the radial deviation of a main machine and a speed reducer is not large, and if the moving position of a movable roller is slightly larger, the flexible coupling or the bearing at the end of the main machine (the speed reducer) is easy to damage.

SUMMERY OF THE UTILITY MODEL

To the above problem, the to-be-solved technical problem of the utility model is to provide a powerful double smooth roller crusher.

The utility model discloses a powerful double-beam roller crusher, it contains host computer, motor, pin shaft coupling, speed reducer and cross axle universal joint, the output of motor is connected with the speed reducer, and is provided with the pin shaft coupling between motor and the speed reducer, the speed reducer passes through cross axle universal joint and is connected with the host computer; the universal joint cross comprises a fork spider flange, a copper sleeve, a sealing cover, a cross shaft, an inner sleeve spider, a flat shaft spider and an oil cup, wherein the cross shaft is arranged at two ends of the universal joint cross, the fork spider flange is arranged outside the cross shaft, the copper sleeve is arranged outside the cross shaft, the sealing cover is arranged above the copper sleeve, the oil cup is arranged on the sealing cover, and the inner sleeve spider and the flat shaft spider are arranged in the middle of the universal joint cross.

Preferably, four groups of copper sleeves are arranged, and the four groups of copper sleeves are symmetrically arranged about the transverse central axis of the cross-axle universal coupling.

Preferably, the inner spider is sleeved on the flat shaft spider, and the joint of the inner spider and the flat shaft spider is fixed through bolts.

Compared with the prior art, the beneficial effects of the utility model are that: the powerful double-light or double-geared roller crusher adopts the design of the universal joint of the cross shaft, so that the requirement of large random displacement in the process of yielding of the movable roller of the crusher is met, the requirement of large random displacement in the process of yielding of the movable roller is met, and the maintenance capital cost and the time cost are effectively saved.
