Abstract
The utility model discloses a transmission structure for a jaw crusher. The transmission structure comprises a motor and a belt pulley. A spindle of the motor is connected with a transmission shaft of the belt pulley through an LM type coupling with elastic spider, two ends of the belt pulley are fixed onto a frame through bearings which are mounted on 'L'-shaped bearing block mounting frames through bearing blocks, and one side of each 'L'-shaped bearing block mounting frame is fixed onto the frame while the other side of each 'L'-shaped bearing block mounting frame is fixedly connected with the bottom of the corresponding bearing block. The motor and the belt pulley are connected through the coupling, and the belt pulley is fixed through the bearings and the 'L'-shaped bearing block supports, so that strength of the motor spindle can be guaranteed, and the motor can operate more efficiently. Further, the transmission shaft is better in transmission and avoids deformation, and accordingly the service life of the transmission structure is prolonged, and efficiency is improved.

In the actual use, along with the increase of jaw crusher model, the model of the motor of being selected for use, power also increase thereupon.The quantity of belt pulley is also increasing thereupon; The size and the V-type groove that are motor pulley are also increasing; Use electric machine main shaft directly to load onto motor pulley, be connected transmission through the V band with the main frame belt pulley again, will weaken the bearing capacity of electric machine main shaft so so greatly; Be easy to cause electric machine main shaft crooked, thus unavailable.
Summary of the invention
The utility model discloses a kind of drive mechanism of jaw crusher according to the deficiency of prior art.The problem that the utility model will solve provides a kind of more reliable and more stable, the jaw crusher drive mechanism of the better and consistency of power transmission shaft transmission.
The utility model is realized through following technical scheme:
The drive mechanism of jaw crusher comprises motor and belt pulley, it is characterized in that: the main shaft of said motor is through the propeller shaft couplings of LM type plum blossom shaft coupling and belt pulley, and bearing fixing is passed through on frame in said belt pulley two ends.
Said bearing is installed on the bearing block installing rack through bearing block, and the bearing block installing rack is " L " shape, " L " one side being fixed on the frame of shape, another side is connected fixing with the bearing block base.
The said belt pulley other end has end cap, labyrinth lid and head plate to pass through bolt successively.
Said belt pulley is fixed on the power transmission shaft through expansion coupling sleeve.
Above-mentioned motor is fixed by bolts on the electric machine support; Electric machine main shaft is connected with LM type plum blossom shaft coupling, and the other end of LM type plum blossom shaft coupling is connected with flat key with power transmission shaft, again through two bearings; Bearing is installed on the bearing block; Bearing block is installed on the electric machine support with bearing bracket, and motor pulley is fixed on the power transmission shaft with expansion coupling sleeve, makes it along with motor rotates together.Reach the purpose of indirect drive.The bearing bracket of " L " shape is had brace rod to form triangle by portion; Bearing and bearing block are installed in one side of " L " shape;, plays by belt pulley stressed supporting role when connecting with jaw crushing machine host belt pulley well; Make the jaw crusher operation more reliable and more stable, the better consistency of power transmission shaft transmission.
In sum, the utility model helpfulness is: the utility model adopts shaft coupling to connect motor and Pulley shaft, and belt pulley is fixed through the bearing bracket of bearing and " L " shape, has guaranteed the intensity of electric machine main shaft, makes the more effective work of motor ability; The better consistency of power transmission shaft transmission has prolonged service life, has improved efficient.
