Description
Technical Field

Background
The plum steel hot rolling 1780 production line vertical roll motor encoder is connected with a motor non-load side motor shaft through a support rod support, an elastic coupling and an encoder connecting shaft head. The stability of the support of the encoder support rod and the connection shaft head is general, steel biting impact is large when steel is fed in rough rolling, and long-time impact vibration easily enables the encoder connection shaft head and the support of the encoder support rod to be loose. The connection between the encoder connecting shaft head and the motor shaft has high coaxiality requirement, the deviation is less than or equal to 0.05mm, and after the coaxiality is deteriorated due to looseness, the elastic coupling is easy to be damaged by metal fatigue, and the data feedback of the encoder is abnormal, so that the main transmission failure reporting and shutdown are caused. The encoder is installed at the non-load side of the motor, the maintenance space is very narrow, and once the coaxiality of the connecting dummy shaft is deteriorated, the difficulty in adjusting the coaxiality on line again is very high.
The vertical roll motor is controlled in a frequency conversion mode, shaft voltage is easily generated between two ends of a rotating shaft or between a shaft and a bearing, if an encoder mounting support and a motor body are not insulated in place, and the potential difference between two ends of the shaft forms a loop through a bearing seat at two ends, the motor body and the like, the shaft voltage forms shaft current to seriously ablate the motor and the encoder bearing, and equipment is damaged. Therefore, the original installation mode of the encoder needs to be improved, and the absolute insulation of the bracket and the motor body is ensured while the stability and firmness of the shaft head and the bracket of the encoder are ensured.
Chinese patent CN103427561A discloses a variable frequency motor encoder installation device, wherein an encoder is connected with a motor shaft through a cylindrical bracket, an elastic coupling and a connecting shaft head. The connection mode of the connecting shaft head and the motor shaft is simple, but the fastener is easy to loose due to vibration. The shaft head mounting mode is only suitable for horizontal motors in general states, and is not suitable for vertical motors under the condition of narrow maintenance space. The degree of difficulty with adjustment pad adjustment spindle nose and motor shaft axiality in narrow and small space is very big, and the spindle nose connected mode of present case design has not only strengthened the spindle nose steadiness, has still saved adjustment pad, adjustment spindle nose and motor shaft axiality that can be convenient relatively.
Chinese patent CN202798352U discloses a brake encoder mounting structure for a motor, wherein an encoder is connected with a motor shaft through a support rod bracket, a shaft coupling and a connecting shaft head. The steadiness is relatively poor under the long-term vibration condition for the bracing piece support, and the bracing piece is longer, encoder and installation switching dish are heavier, and the steadiness of bracing piece support is just poor more, and the fastener is not hard up more easily, and encoder job stabilization not only can make the shaft coupling life-span greatly reduced of encoder, still can cause encoder data feedback unusual, arouses that the main drive reports the breakdown shutdown. The stability of the cylindrical bracket designed by the scheme is greatly superior to that of a supporting rod bracket.
