Two axles couple, to realize the connection of two axles, transmit torque and motion.Flange-face coupling is simple in construction, easily manufactured, and cost is relatively low,
Reliable operation, assembly and disassembly, safeguard easier, it is larger to transmit torque, but flange-face coupling does not possess radially, axially and angular compensatory
Performance, therefore requirement of the flange-face coupling to two shaft assignments is very high, if it cannot be guaranteed that coupled two shaft assignments essence during use
Spend, when having relative displacement between two axles, it will reduce service life, transmission accuracy and the transmission efficiency of shaft coupling, and cause and shake
Dynamic and noise, makes to cause additional load in parts, and working condition deteriorates.The reactor agitating shaft used in the production of a- leukotrienes
Longer, the ratio of height to diameter of reactor is very big, and mixing speed is very fast, and material viscosity changes very greatly in urine job contract skill, stirs resistance
It is very big, therefore very high is required to the alignment degree of agitating shaft and reductor shaft, typically require that agitating shaft exists in circular runout control
0.15mm or so, end face run-out error are no more than 0.2mm, therefore need to use dial gauge measurement connection during installation agitating paddle every time
Axle device clipping room also often reduces production away from being wasted time and energy with installation perpendicularity, installation because of agitating shaft vibration problems shutdown maintenance
Efficiency.
The content of the invention
The purpose of this utility model is：There is provided a kind of reactor agitating paddle main shaft connection structure, it is ensured that reductor
And two shaft assignment precision of mixing paddle axle, it is simple in construction, easy for installation, the set-up time can be saved, improves operating efficiency.
To realize object above, the technical scheme that the utility model is taken is：Reactor agitating paddle main shaft connection structure, bag
Reductor main shaft, agitating paddle main shaft are included, the reductor main shaft end is provided with splined shaft, and the agitating paddle main shaft end is set
There is spline housing, the bottom of splined shaft is taper, and the keyway both sides upper end in spline housing is provided with arc angling, reductor
The spline housing that the splined shaft that main shaft end is set is set with agitating paddle main shaft end collectively constitutes spline fitted, and splined shaft direction subtracts
One end of fast machine is additionally provided with fixed disk A, offers connecting hole A on fixed disk A, and the spline housing end on agitating paddle main shaft is set
There is fixed disk B, the position that connecting hole B, connecting hole A and connecting hole B are offered on fixed disk B is mutually correspondingly arranged, in spline housing
It is connected after coordinating with splined shaft using screw bolt and nut；The connecting portion of the reductor main shaft and fixed disk A is circular arc mistake
Cross structure, connecting hole A, connecting hole B bore dia 1-2mm big compared with the diameter of bolt；The agitating paddle main spindle multiple spline set lower section is set
It is equipped with mounting knob.
Actively advantageous effects of the present utility model are：The utility model is using spline fitted connection agitating paddle main shaft
With reductor main shaft, spline fitted is due to multiple tooth work, and bearing capacity is high, when reaction fluid viscosity is larger using the present apparatus still
It can ensure to run well, centering is good, and because splined shaft is good with guidance quality that spline housing coordinates, it is numerous to eliminate installation shaft coupling
Trivial installation centering debugging process, installation process is extremely simple, splined shaft towards reductor one end set fixed disk A and
The fixed disk B that the end of spline housing is set, after being bolted, can be avoided between agitating paddle main shaft and reductor main shaft
Axial float, ensure the normal operation of equipment, circular arc transition knot is set in reductor main shaft and fixed disk A connecting portion
Structure, the stress concentration caused by the abrupt change of cross-section can be avoided and cause the connecting portion of reductor main shaft and fixed disk A to be broken；
Agitating shaft main spindle multiple spline set lower section sets mounting knob to use when mounted and Hand supplementary is determined installation site, improves installation
Speed, by probation, attachment structure is easy for installation, efficiency high, long lifespan.
