Description
Technical field
The utility model relates to the frock technical field, particularly a kind of transmission long axis alignment and adjustment device.
Background technology
Shaft coupling generally is used for connecting driving shaft and the driven shaft in the rotating machinery, makes the common rotation of driving shaft and driven shaft to transmit moment of torsion.Shaft coupling is in installation process, and centering and centering so that the pivot of two axles that shaft coupling connected is strictly concentric, otherwise can cause that the vibration values of rotating machinery exceeds standard accurately.If the driving shaft of rotating machinery and driven shaft decentraction when equipment rotates, will cause very big stress so on shaft coupling, and will have a strong impact on the normal operation that rotating shaft, bearing and axle are gone up other parts.Particularly for the equipment that runs up, it is very important that shaft coupling is carried out centering.But, can not be accurately absolute owing to make and install, and during rotating shaft work stand under load, be subjected to the influence of frame and miscellaneous part strain and temperature deformation, relativity shift will take place in diaxon that shaft coupling connected inevitably, so the centering of shaft coupling is a very important working link in rotating machinery installation and the maintenance process.Generally all need transmission long axis to connect the driving shaft and the driven shaft of rotating machinery in the main equipment, the transmission long axis of existing main equipment is generally all long, and weight is bigger; When transmission long axis alignment, the general two ends ways of connecting that adopts is carried out centering to the transmission long axis two ends simultaneously, centering is regulated the difficulty height, labour intensity is big, adjust data and be not easy control, make the driving shaft that shaft coupling and the transmission long axis at transmission long axis two ends need be connected and the shaft coupling centering difficulty of driven shaft.
Summary of the invention
The technical problems to be solved in the utility model is, provides a kind of simple in structure, and the convenient shaft coupling of regulating the transmission long axis two ends carries out the transmission long axis alignment and adjustment device of centering.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is: transmission long axis alignment and adjustment device, it is characterized in that: comprise formed steel base, bearing support, bearing bracket stand, bearing and transmission long axis, the formed steel base upper end is horizontally disposed with two nuts, bearing support places on the formed steel base, between two nuts, horizontal adjustment bolt is passed the contacts side surfaces of nut and bearing support; Bearing support is provided with two double-screw bolts of regulating height, the bearing support upper end connects two bearing bracket stands, a bearing is rotationally connected on each bearing bracket stand, two bearings transmission long axis, bearing axially and transmission long axis axially identical, distance between the two bearings is greater than the radius of transmission long axis, less than the diameter of transmission long axis.
Further, the axis of two nuts is on same straight line.
Two horizontal adjustment bolt can be fixed on bearing support the arbitrary horizontal level between two nuts.
Double-screw bolt is by the bearing support that is threaded, and the one end passes bearing support and contacts with formed steel base, and the other end exceeds bearing support.
Double-screw bolt is positioned at the outside of bearing bracket stand.
The utility model supports transmission long axis with two rolling bearings, make things convenient for transmission long axis to rotate like this, when centering transmission long axis concentricity, two bearings is rotated with major axis, help transmission long axis alignment, make things convenient for the shaft coupling of transmission long axis end to align and be connected with the shaft coupling of driving shaft and driven shaft end.The bearing support of rigid bearing and bearing bracket stand can move horizontally on formed steel base, and can be fixed on arbitrary position between two nuts by the turn horizontal adjustment bolt.Can regulate the horizontal level of bearing support on base easily like this, also just realize transmission long axis left and right adjusting in the horizontal direction.The height of bearing support can be regulated by the double-screw bolt of bearing support both sides, the turn double-screw bolt can make bearing support away from or near formed steel base, so just realized transmission long axis upper and lower adjusting in vertical direction.Double-screw bolt is arranged on the outside of bearing bracket stand, can make things convenient for user's turn double-screw bolt like this.
When using the utility model to carry out transmission long axis alignment, the transmission long axis that is bearing on the bearing top circle promptly can carry out left and right adjustment in the horizontal direction, simultaneously can carry out upper and lower adjustment at vertical direction again, so it is simple, convenient in the centering process, and the utility model is simple in structure, low cost of manufacture, when the transmission long axis to large scale, long distance carries out centering, save time, laborsaving, efficient is high.
In sum, the utlity model has simple in structurely, the convenient shaft coupling of regulating the transmission long axis two ends carries out the beneficial effect of centering.
