Description

Torque supporting structure for roller press

Technical Field

The utility model relates to a roll squeezer technical field specifically is a moment of torsion bearing structure for roll squeezer.

Background

With the rapid development of national economy, the requirements of the whole society on energy conservation and emission reduction are continuously improved, the production scale of production enterprises such as building material cement, metallurgical mines, chemical engineering and the like tends to be large-scale, the production line also tends to be large-scale, the grinding equipment is inevitably required to adopt equipment with low energy consumption and high efficiency, the large-scale of a roller press (a high-pressure roller mill) is inevitably trend, and the large-scale roller press (the high-pressure roller mill) correspondingly needs to be matched with a speed reducer to adopt a high-power speed reducer, so that the requirement of the high-power speed reducer is higher and.

See fig. 1, patent CN 207385688U discloses a single-support torque support system for a roller press, which transmits the torque generated by the operation of a speed reducer to a support and a base 3 through a torque disc 1 and a support rod 2, and since the two ends of the support rod 2 are connected in a manner of rotating through a joint bearing, the support rod 2 can rotate left and right, so as to adapt to the horizontal movement of the speed reducer. Meanwhile, patent CN 102228848A discloses an independent torque support structure (see fig. 2) for a roller press (high-pressure roller mill), which eliminates the mutual influence between high-power speed reducers, prolongs the service life of the high-power speed reducer for the roller press (high-pressure roller mill), reduces the vibration of the roller press (high-pressure roller mill), improves the applicability to materials, and ensures the stable operation of the roller press (high-pressure roller mill). However, because the torque direction of the outer shell of the planetary reducer is opposite to the rotating speed direction of the transmission shaft, the strut 2 hinged with the support and the base through the hinged 3 at the bottom end is always under the action of compressive stress, if the mechanism is originally installed incompletely, the mechanism cannot reach a self-balancing state, and the strut 2 (a balancing rod) can move under the action of the compressive stress to reach a self-adaptive state. In addition, when the speed reducer shafting of the roller press rotates, the torque plate 1 and the strut 2 (balance bar) rotate back and forth due to the time variation of the roll gap deviation, so the strut 2 (balance bar) is easily contacted and worn with the torque plate 1, the joint bearing is not flexible in rotation in severe cases, and the torque plate 1 is stressed and deformed. Secondly, all torque supporting rotors are not safe and do not meet the mechanical safety standard (GB/T8196-.

The balance bar is of an H-shaped rod-shaped structure, the support is located in an upper notch in the upper portion of the balance bar and is hinged to the upper portion of the balance bar through a joint bearing, a pin shaft and a locking nut, and the other end of the torque plate extends into a lower notch in the lower portion of the balance bar and is hinged to the lower portion of the balance bar through the joint bearing, the pin shaft and the locking nut.

The base still including back closing plate and elastic sealing plate, the top fixed connection of back closing plate on the rear end of entablature, the bottom fixed connection of back closing plate is on the rear end of bottom end rail, the two vertical sides of back closing plate respectively with the rear end fixed connection of two upright roof beams, elastic sealing plate's width be not less than two horizontal distances of founding between the roof beam, the top of elastic sealing plate and the front end fixed connection of entablature, the bottom of elastic sealing plate and the front end fixed connection of bottom end rail, the other end of torque plate pass behind the elastic sealing plate articulated with the bottom of balancing pole, and elastic sealing plate and torque plate fixed connection.

The utility model has the advantages that:

because the torque direction of the planetary reducer shell is opposite to the rotating speed direction of the transmission shaft, and the balance rod is under the dual action of gravity, the balance rod is always under the tensile stress state, the problem that the balance rod moves under the action of pressure stress to seek the self-adaptive state in the original structure is avoided, the problem of contact wear of the balance rod and the torque plate is solved, and the problem that the torque plate is distorted and deformed due to larger axial force is also solved. Because the utility model discloses be connected with back closing plate and elastic sealing plate on the crane span structure formula mount pad, seal up balancing pole rotating part through two closing plates, firstly strengthen the protection to joint bearing, reduce the dust and get into, secondly reach mechanical safety standard (GB/T8196) and give first place to 2003), accord with the national standard.
