[background technology]
In recent years, due to China new economy rapid growth factor, the development that heavy industry is advanced by leaps and bounds.As: the industries such as electric power, mine, chemical industry directly cause the sought-after of the energy, the degree relying on the energy also increases, but the energy utilization rate of China is but far below world average level, country proposes will make great efforts to utilize resource to raise the efficiency, so Energy Saving Industry high voltage converter also drives fast-developing situation thereupon.Vector control High-power Synchronous Motor effectively can solve the large problem with running step-out speed adjustable range difference of inrush current of High-power Synchronous Motor, but the main shaft that existing existing problem is vector control High-power Synchronous Motor to be connected main shaft High Rotation Speed with spring during by being flexible coupling, move axially and encoder is caused damage, running accuracy error is too large, its useful life can be shortened, original spring be flexible coupling mode make encoder measure inaccurate, the moment rotated is started at motor, there is hysteresis, error advanced when stopping instantaneously.
Therefore; for overcome above-mentioned technology deficiency and design a can Intelligent adjustment motor speed; transmission accuracy is high, and response is fast, and dynamic stability is good; defencive function is perfect; volume is little, and structure is simple, and price is low; observe the operation and maintenance energy-conservation jockey of a kind of motor shaft end easily, inventor's problem to be solved just.
[utility model content]
For the deficiencies in the prior art; the purpose of this utility model is to provide the energy-conservation jockey of a kind of motor shaft end, can Intelligent adjustment motor speed, and transmission accuracy is high; response is fast; dynamic stability is good, and defencive function is perfect, and volume is little; structure is simple; price is low, observes operation and maintenance convenient, can solve the inrush current of High-power Synchronous Motor large and run step-out speed adjustable range difference problem.
For achieving the above object, the utility model can adopt following technical scheme: the energy-conservation jockey of a kind of motor shaft end, it comprises load motor main shaft, shaft joint, circumference connector, be flexible coupling, ring flange, encoder, described load motor main shaft and shaft joint to be connected bolted by seam, encoder is arranged on the two-way seam of ring flange, shaft joint is connected with circumference connector, and described circumference connector fits through bolt and is connected with encoder with being flexible coupling.
Further, described load motor spindle end and shaft joint adopt dynamic being connected.
Further, described circumference connector material 27SiMn steel Surface heat-treatent HRC50 ~ 53, coordinate double-faced clearance ± 0.05.
Compared with prior art, the beneficial effects of the utility model are:
1, frequency converter output data line connects encoder, the axle head of encoder is connected with high power DC electric machine axle head, connected mode is with electric machine main shaft and encoder connecting device, dependable performance, easy for installation, cheap, processing is simple, transmits data accurate, ensure that the operation of total system safety.
2, encoder is used for the testing the speed of heavy-duty motor that high voltage converter drags, and the data feedback recorded by encoder is to frequency converter thus reach the object of Intelligent adjustment motor speed.
3, the mode adopting the spring be flexible coupling to connect; when this connected mode solves main shaft High Rotation Speed; main axial motion to the infringement of encoder, circumference jockey achieve encoder is connected effectively accurately with electric machine main shaft and also transmission accuracy high, respond soon; dynamic stability is good; defencive function is perfect, and volume is little, and structure is simple; price is low, observes operation and maintenance convenient.
[accompanying drawing explanation]
Fig. 1 is the utility model structural representation.
Description of reference numerals: 1-load motor main shaft; 2-outer race seat; 3-shaft joint; 4-has an area of connector; 5-is flexible coupling; 6-ring flange; 7-encoder; 8-bolt; 9-motor bearings device.
[embodiment]
Below in conjunction with specific embodiment, set forth the utility model further, should be understood that these embodiments are only not used in restriction scope of the present utility model for illustration of the utility model.In addition should be understood that those skilled in the art can make various changes or modifications the utility model after the content of having read the utility model instruction, these equivalent form of values drop on application appended claims limited range equally.
As shown in Figure 1, the energy-conservation jockey of a kind of motor shaft end of the utility model, it comprises load motor main shaft 1, outer race seat 2, shaft joint 3, circumference connector 4, be flexible coupling 5, ring flange 6, encoder 7, motor bearings device 9, described load motor main shaft 1 is arranged on inside outer race seat 2, described load motor main shaft 1 and shaft joint 3 are fastening by the seam bolt 8 that is connected, power transmission is made to arrive circumference connector 4, be transferred to by circumference connector 4 and be flexible coupling 5, 5 encoder 7 is transferred to by being flexible coupling, encoder 7 is arranged on the two-way seam of ring flange 6, position assurance at different levels encoder 7 and load motor main shaft 1 center line axiality, shaft joint 3 is connected with circumference connector 4, both can transfer of torque, can axially be free to slide again, this slip axial force absorbed by circumference connector 4, the axial force protecting encoder 7 is not compromised.
Load motor main shaft 1 end and shaft joint 3 adopt dynamic being connected, and circumference connector 4 material 27SiMn steel Surface heat-treatent HRC50 ~ 53, coordinate double-faced clearance ± 0.05, and circumference connector 45 fits through bolt 8 and is connected with encoder 7 with being flexible coupling.With the two-way seam of ring flange 6, encoder 7 is connected to make encoder 7 and load motor main shaft 1 center line coaxial line with motor bearings device 9 hi-Fix, ensure that technical requirement on design.
The utility model frequency converter output data line connects encoder 7, the axle head of encoder 7 is connected with high power DC electric machine axle head, connected mode is with load motor main shaft 1 and encoder 7 jockey, dependable performance, easy for installation, cheap, processing is simple, transmits data accurate, ensure that the operation of total system safety.Testing the speed of the heavy-duty motor that encoder 7 drags for high voltage converter, the data feedback recorded by encoder 7 is to frequency converter thus reach the object of Intelligent adjustment motor speed.The mode that the utility model adopts the spring being flexible coupling 5 to connect; when this connected mode solves main shaft High Rotation Speed; main axial motion to the infringement of encoder, circumference jockey achieve encoder is connected effectively accurately with electric machine main shaft and also transmission accuracy high, respond soon; dynamic stability is good; defencive function is perfect, and volume is little, and structure is simple; price is low, observes operation and maintenance convenient.Be applied to mining hoist, pass through through on-the-spot bringing onto load runtime verification, this utility model solves the problems such as the inrush current of High-power Synchronous Motor is large and operation step-out speed adjustable range is poor.
