Definitions
- the present invention relates to a jaw crusher for crushing materials with at least one moving crushing jaw which is brought into contact with an eccentric unit having a drive shaft such that the crushing jaw performs a periodic rotary lifting movement, and wherein the eccentric unit has at least one counterbalancing mass rotating about the drive shaft.
- FIG. 1 shows by way of example a genus-forming jaw crusher 1 for
- the jaw crusher 1 has a moving crushing jaw 10 and a resting crushing jaw 25, the latter being rigidly received in a frame 26 of the jaw crusher 1.
- the moving crushing jaw 10 is provided with a
- Exzenterica 12 offset in a periodic rotary stroke movement, wherein the rotary stroke movement by a superposition of a rotary movement 22 and a Lifting movement 24 is formed.
- the rotational movement 22 takes place about a pivot point 23 which, however, likewise carries out a lifting movement by the superposed lifting movement 24 in the direction of the longitudinal extent of the crushing jaw 10.
- the crushing jaw 10 is connected via a pressure plate 27 with a device for gap adjustment 28, so that the pressure plate 27 also performs a pendulum motion in the direction of the arrow shown. This results in a movement that is related to the movement of a connecting rod in a reciprocating engine.
- the eccentric unit 12 is located at the upper end of the crushing jaw 10, wherein the crushing jaw 10 comprises a crushing rocker 29, to which the crushing jaw 10 is received and over which the crushing jaw 10 is connected to the eccentric unit 12. Subsequently, the dynamically moving unit of crushing jaw 10 and crushing rocker 29 is simply referred to as crushing jaw 10.
- the Exzentereirthett 12 includes a drive shaft 11 » and a portion of the Exzentereinhert 12 rotates about the drive shaft 11 for coupling the
- Crushing rocker 29, the section having an eccentricity e If the drive shaft 11 is set in rotation, then the crushing rocker 29 rotates with the crushing jaw 10 in its upper portion with the eccentricity e about the central axis of the drive shaft 11. To compensate for the resulting mass forces from the movement of the crushing jaw 10, a balancing mass 13 is known to be attached to a flywheel 30.
- FIG. 2 a schematically shows the crushing jaw 10 in two positions. It is indicated that the crushing jaw 10 is received in the lower region via the pressure plate 27 oscillating, and in the upper region of the crushing plate 10 is arranged on the eccentric unit 12 at a distance according to the eccentricity e to the axis of rotation of the drive shaft 11. Due to the rotation of the drive shaft 1 1, the eccentricity e at the upper end of the crushing jaw 10 can double, so that the maximum distance of movement of the upper end of the crushing jaw 10 of the double eccentricity corresponds to 2e.
- the balancing mass 13 can be determined so that the movement of the center of gravity S of the crushing jaw 10 and the crushing rocker 29 is compensated by the balancing mass 13 accordingly.
- Jaw crushers of the present type can be designed both as a stationary, as a semi-mobile or as a mobile jaw crusher.
- Mobile jaw crushers are housed on a chassis, and can, for example, self-propelled be moved to an appropriate location.
- Such jaw crushers, which are mounted on a chassis, create significant problems in operation when vibrations can not be absorbed by a foundation, such as a stationary jaw crusher which can be received over a ground foundation.
- the invention includes the technical teaching that at least one additional compensation mass is provided and that carries out a rotational movement which is opposite to the rotational movement of the balancing mass.
- the invention is based on the idea that a reduction of mass forces, which arise from the rotary stroke movement of the crushing jaw, can be significantly improved with at least one further additional balancing mass in addition to the balancing mass on the drive shaft.
- the basic idea is that the imbalance forces from the Aus GmbHsmasserl can add or subtract depending on the phase position of both rotating masses, which also changes periodically by the rotation of the balancing weights of the resulting mass balance with the Drehhubterrorism.
- the phased addition or subtraction of the mass forces is possible when the additional compensation mass performs a rotational movement which is opposite to the rotational movement of the balancing mass.
- the balancing mass and the additional balancing mass can be, for example, on opposite sides relative to the drive shaft, so that a resulting balancing mass force results, which corresponds to the difference of the balancing mass force to the additional balancing mass force due to a subtraction to be formed. If the balancing mass and the additional balancing mass are located on a common side with respect to the drive shaft, then the mass forces add up to an overall balancing mass due to an addition to be formed,
- Jaw crusher can rotate the additional balancing mass to the drive shaft and be stored in particular on this.
- the weight of the additional balancing weight may differ from the weight of the balancing weight, for example, the weight of the additional balancing weight may be less than the weight of the balancing weight.

- the additional balancing mass in its rotation about the drive shaft have a phase position which is opposite to the phase position of the balancing mass with respect to the drive shaft in the horizontal.
- an effective mass force corresponding to the mass force difference between the balance mass force and the auxiliary balance mass force is formed.
- a mass balance of the rotational movement of the crushing jaw can be done around its fulcrum. Due to the eccentricity e, which describes the maximum deflection of the center of gravity S of the crushing jaw, in the horizontal only a smaller effective balancing mass force is required.
- the horizontal only describes an approximately horizontal region, and due to the inclination of the crushing jaw, this can be somewhat out of the vertical extend out so that the rotational movement is not exactly in the horizontal.
- a comparison of the balancing mass and the Vietnamese outsmasse may be present relative to the drive shaft when the connecting lines between the opposite positions of the balancing mass is approximately perpendicular to the extension direction of the crushing jaw.
- the additional balancing mass can in its rotation around the drive shaft at a different time point autogenous a phase position, which is designed so that it lays with the balancing mass with respect to the drive shaft in the vertical on the same side.
- the vertical also describes only an approximately vertical course, and lying on a same side masses with respect to the drive shaft can give a resulting direction to the axis of rotation of the drive shaft, which corresponds to the extension direction of the crushing jaw
- a total compensation mass force which may be determined so that the mass forces are compensated from the lifting movement of the crushing jaw. Due to the stroke which corresponds to the double eccentricity 2e, a larger compensating force is required, which can be provided by the addition of the two balancing mass forces, if they are on the same side relative to the drive shaft.
- the beauticianichsmasse may be coupled mechanically and in particular by means of a synchronization gear with the balancing mass.
- the synchronization gear can be designed so that the common with the balancing weight mounted on the drive shaft mouldausgieichsmasse has a reverse rotation direction to the direction of rotation of the drive shaft.
- the synchronization gear may comprise a double bevel gear stage with a bevel gear, which engages simultaneously in two opposite and connected to the respective mass sprockets.

- the advantage is achieved that in addition to the compensation of earth cracks from the Rotary movement and from the lifting movement of the crushing jaw further arising moments can be compensated.
- the desired balancing effect can also be achieved by further balancing shafts, so that in particular then several balancing shafts are useful.
- a further possibility for optimization consists in the installation of additional balance shafts, which rotate at twice or an integral multiple of the working speed of the drive shaft, so that it is also possible to eliminate portions of the harmonic multiples of the fundamental vibration of the crushing jaw.
