Abstract
The invention relates to the field of mechanical assembly, in particular to a method for improving the coaxiality of couplers. The method is characterized in that a transmission shaft assembly standard sample is adopted to pre-adjust the position of a motor, so that the coaxiality deviation during assembly of a transmission shaft is reduced. The method comprises the steps that firstly, the transmission shaft assembly standard sample is made; secondly, the transmission shaft assembly standard sample is assembled between a reducer shaft and the motor through bolts, the motor is straightened through a double-surface outer circle end face method with the axis of the reducer shaft as the datum, and bottom legs of the motor are adjusted so that the coaxiality deviation between a motor shaft and the reducer shaft can be within the range of 0.09-0.15 mm; thirdly, the transmission shaft assembly standard sample is dismantled, and the transmission shaft is assembled between the reducer shaft and the motor through a gear coupler connector. Compared with the prior art, the method has the advantages that the transmission shaft assembly standard sample is adopted for pre-adjustment, the influence of gaps between inner teeth and outer teeth of the gear coupler is eliminated, and therefore stable and safe running of a crane is guaranteed.
Description
Technical field
The present invention relates to mechanical assembling field, relate in particular to a kind of method that improves coupling coaxality.
Background technique
The crane master transmission shaft that hoists is the parts that connect motor and speed reducer, and its two ends coupling model is G II CLZ9J1110 * 167, the form that employing ring gear is meshed with external toothing.After general replacement motor, have larger error beating when dial gauge is adjusted motor with speed reducer coaxality, more than reaching 1mm, the existence of this error is because the transmission shaft downward sedimentation of its body and the coupling causing of conducting oneself with dignity exists inter-lobe clearance to cause.The existence of this error causes the connecting bolt of coupling of M10 also will bear the moment of torsion causing because of moment of flexure except being subject to shearing force, each bolt can produce alternating stress in the process of rotating with axle, cause bolt fatigue, fracture, when transmission shaft both sides bolt is during by simultaneously " cutting off ", will cause heavy tank out of control, the serious accident on the unrestrained ground of molten iron.
Summary of the invention
The object of this invention is to provide a kind of method that improves coupling coaxality, eliminate the impact of the inside and outside backlash of gear coupling, solve the hoist low problem of coaxial accuracy of transmission shaft two ends gear coupling of crane master.
For achieving the above object, the present invention is achieved through the following technical solutions:
Improve a method for coupling coaxality, adopt transmission shaft assembling standard specimen to carry out the position of motor presetting, reduce the coaxiality deviation of drive shaft cartridge timing, its concrete operation step is as follows:
1) make transmission shaft assembling standard specimen, comprise catcher one, catcher two and coupling shaft, catcher one and catcher two are divided into the two ends of coupling shaft, and the mounting hole on catcher one and speed reducer one axle side coupling catcher match, and the mounting hole on catcher two and motor side coupling catcher match;
2) transmission shaft being assembled to standard specimen uses bolts assemblies between speed reducer one axle and motor, take speed reducer one axle axle center is benchmark, adopt two table circle end face methods to carry out centering to motor, adjust motor foot, make coaxiality deviation between motor shaft and speed reducer one axle within the scope of 0.09～0.15mm;
3) transmission shaft is assembled to standard specimen and pull down, with gear coupling catcher, transmission shaft is assembled between speed reducer one axle and motor.
Described bolt is driving fit bolt.
Compared with prior art, beneficial effect of the present invention is:
Adopt transmission shaft assembling standard specimen to carry out presetting to the mounting point of the coupling between motor and speed reducer, eliminated the impact of the inside and outside backlash of gear coupling, improve the coaxality of assembling between motor and speed reducer, improve the Security of connecting bolt of coupling, thereby guaranteed stable, the safe operation of crane.
Accompanying drawing explanation

Fig. 2 is the normal assembling condition schematic diagram of the embodiment of the present invention.
In figure: 1-takes over a 2-and takes over two 3-speed reducer one axle side coupling 4-motor side coupling 5-transmission shaft 6-gear coupling one 7-gear coupling two 8-coupling shaft 9-bolts
Embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described further:
A kind of method that improves coupling coaxality of the present invention is exactly presetting by adopting transmission shaft assembling standard specimen first the position of motor to be carried out, the coaxiality deviation while reducing transmission shaft 5 assembling, and its concrete operation step is as follows:
1) make transmission shaft assembling standard specimen, comprise catcher 1, catcher 22 and coupling shaft 8, take over one 1 and catcher 22 two ends that are divided into coupling shaft 8, the mounting hole on catcher 1 matches with speed reducer one axle side coupling 3 catchers, and mounting hole and the motor side coupling 4 taken on 22 match;
2) see Fig. 1, transmission shaft is assembled to standard specimen to be assemblied between speed reducer one axle and motor with bolt 9, take speed reducer one axle axle center is benchmark, adopt two table circle end face methods to carry out centering to motor, dial gauge is beaten on the motor side coupling 4 of rigidity, coiled manually Brake drum and rotate, record and analyze the numerical value of four points up and down, adjust motor foot, make coaxiality deviation between motor shaft and speed reducer one axle at 0.09～0.15mm; The driving fit bolt that bolt 9 is M10 * 65;
3) transmission shaft is assembled to standard specimen and pull down, with gear coupling 1 and gear coupling 27, transmission shaft 5 is assembled between speed reducer one axles and motor, see Fig. 2, motor can normally move.
