Description

The invention relates to crushing equipment and can be used as a drive cone or jaw crushers.

Known drive crusher, made in the form of a planetary gear with non-circular satellites, drove associated with the output shaft having a central wheel (1).

The crusher drive is also known, which contains a drive shaft, an output shaft with a central disk and a working body, a carrier associated with diametrically located satellites having unbalances and interacting with the sun wheel, and an eccentric shaft {21.

The disadvantage of the known drive is that the carrier serves as both a drive and a driven member, which does not allow to use significant unbalance masses in the drive and create dynamic moments on the output shaft that are larger than the steady-state static moment that the engine could develop .

The purpose of the invention is the possibility of increasing the drive power by increasing the dynamic moments at the output shaft and unloading the carrier.

This goal is achieved by the fact that in the crusher drive containing a drive shaft, an output shaft with a central disk and a working body, the carrier connected to diametrically located satellites, having unbalances and interacting with the sun wheel, and an eccentric shaft, has an additional eccentric shaft, and the central disk and the carrier are made with holes in which the ends of the eccentric shafts are freely installed, the satellites being rigidly fixed on the crankshafts.

FIG. 1 shows the kinematic diagram of the crusher drive; in fig. 2 - section A — A in FIG. one; in fig. 3 is a section BB in FIG. one.

The drive of the crusher includes a drive shaft from the engine 1 with a sun wheel 2 attached to it, inserted into the tooth 914082

chatoe engagement with diametrically arranged in pairs and the satellite 3, which are provided with defined protnvofazno unbalance 4 and fixed to the eccentric shaft 5, which ends freely installed in openings ₅ Lena central disc 6 fastened to the output shaft 7 carrying a working member, e.g., crushing cone eight.

Opposite ends of the shafts 5 are installed on the carrier 9, equipped with an autologue 10, closed on the housing 11.

The drive is as follows.

From the drive shaft 1, rotating the sun wheel 2 counterclockwise, the satellites and 3 will rotate clockwise. In addition, the out-of-phase placement of the unbalances 4 on the satellites 3 affects the carrier 9, causing the latter's ability to perform torsional vibrations (Fig. 2). The impulse in this direction is completely transmitted to the output shaft 7. Through the half-turn of the satellites 3 their debalans will take the opposite position and create on the carrier 9 negative pulse (with respect to the rotation of the satellites) moment. However, this moment will not be transmitted to shaft 7, since the carrier 9 cannot rotate counterclockwise due to the fact that its autologue 10 will be closed to the body 11. _{3 £)}

When the carrier 9 remains inhibited, and there is a "discharge" satellites 3, the latter continues to rotate clockwise, carrying ea a shaft 7 which, together with the disk 6 will perform only circular vibrations. After the "discharge" satelli- ³⁵ comrade cycle repeated.

The proposed drive design provides intensification of the crushing process.

through complex rotation of the output shaft at the expense of circular oscillations continuously transmitted to this shaft from the rotation of the satellites around their axes, and with an amplitude equal to the eccentricity of the satellite shafts, and also due to periodically acting on the output shaft, and only unidirectional pulses creating Uneven circular rotation of the carrier and the output shaft (during periods of no “discharge” of the satellites).
