A stable bearing structure for electric motor

Abstract

The present invention discloses a stable bearing structure for an electric motor, comprising a supporting base, a positioning bracket, an electric motor body, an abutment plate, and a stabilizing control component. When the electric motor body is subjected to high-intensity operation, once the bolts become loose, the abutment plate and the positioning bracket become loose and vibrate, and the abutment plate portion on one side of the loosened bolts vibrates more violently, and therefore the induction spring column on the lower side of the violent vibration point is most violently stretched and compressed, and therefore the corresponding pressure sensor sends a pressure signal to the controller, and the controller drives the corresponding power unit, so that the power unit drives the abutment rod at the corresponding position to press upward into the abutment groove, thereby achieving reinforcement of the vibrating portion of the abutment plate, thereby achieving flexible monitoring, and improving the emergency flexibility and stability of the structure.

Description

Technical Field

[0001] The invention relates to a stable bearing structure of a motor. Background Art

[0002] When installing existing motors, they are directly installed and fixed using the mounting holes on the motor base. This installation method requires that the fixing bolts have a certain strength to meet the installation environment under various stress conditions. However, for some motors that operate at high intensity, such an installation method that relies solely on bolt assemblies for fixing cannot guarantee the smooth operation of the motors, especially for three-phase AC motors, which require a very high degree of stability. After the existing motors are installed on the base by bolts, once the motor becomes loose, it is necessary to immediately stop the operation, shut down for maintenance, and reinstall the connection. In this way, there is no emergency response method, and interrupting the operation will have serious consequences in some places of use. Therefore, it is necessary to improve the stability of motor installation and use and the flexibility of emergency. Summary of the invention

[0003] In view of the above-mentioned deficiencies in the prior art, the present invention solves the problem of providing a stable bearing structure for an electric motor with high stability in use and high flexibility in emergency situations.

[0004] To solve the above problems, the technical solution adopted by the present invention is as follows:

[0005] A motor stable bearing structure comprises a supporting base, a positioning bracket, a motor body, an abutment plate, and a stabilization control component; a positioning bracket is respectively installed on both sides of the upper end of the supporting base; an abutment plate is respectively installed on both sides of the lower end of the motor body; the upper side of the abutment plate abuts against the lower side of the positioning bracket, and the abutment plate and the positioning bracket are evenly fixedly connected by multiple bolts; a driving cavity is provided inside the supporting base; the stabilization control component comprises an induction spring column, a pressure sensor, an abutment rod, a controller, and a power unit; a plurality of abutment grooves are evenly provided on the lower side of the abutment plate from front to back; a plurality of induction spring columns are evenly installed on both sides of the upper end of the supporting base from front to back; a plurality of pressure sensors are evenly connected around the lower end of the induction spring column, and the pressure sensors are fixedly installed on the supporting base The upper end surface of the seat; the upper end of the induction spring column is connected to the lower side surface of the abutment plate, and the upper end of the induction spring column is located on the outside of the abutment groove; the interior of the induction spring column floats up and down and passes through a pressure rod, the lower end of the pressure rod passes through the supporting base and extends into the driving cavity, the lower end of the pressure rod is connected to a power unit, the power unit is installed in the driving cavity, and the upper end of the pressure rod corresponds to a pressure groove; the controller is installed inside the driving cavity, and the controller signal connects the pressure sensor and the power unit; when the abutment plate becomes loose and vibrates, the induction spring column on the lower side of the abutment plate is stretched and squeezed, and the pressure sensor sends a pressure signal to the controller, and the controller drives the corresponding power unit to drive the corresponding pressure rod to press upward into the pressure groove and stabilize the loose position of the abutment plate.

[0006] Furthermore, the power unit includes a power motor, a power shaft, a rotating rod, and a movable plate; multiple power motors are evenly installed on both sides of the bottom of the driving cavity of the support base from front to back, and a power shaft is installed on the upper end of each power motor, and the upper end of the power shaft is connected to the rotating rod; movable plates are installed on the outer side of the lower end of the pressure rod, and the movable plates are slid up and down and clamped in the driving cavity, and the movable plates are respectively screwed with a rotating rod.

[0007] Furthermore, a plurality of longitudinal tracks are evenly arranged on the inner walls on both sides of the driving cavity of the support base; and the outer end of the movable plate slides up and down and is clamped on the longitudinal tracks.

[0008] Furthermore, a plurality of rotation holes are evenly arranged on both sides of the upper end of the driving cavity of the support base; and the upper end of the rotation rod is rotatably clamped on the rotation hole.

[0009] Furthermore, a plurality of plug-in protrusions are evenly arranged on the upper side of the abutment plate; a plurality of plug-in grooves are evenly arranged on the lower side of the positioning bracket; and the plug-in protrusions are upwardly plugged into the plug-in grooves.

[0010] Furthermore, a pressing groove is correspondingly distributed on the inner side of each of the bolts.

[0011] Furthermore, a plurality of through holes are evenly formed on the abutment plate, and a plurality of screw holes are evenly formed on the lower side of the positioning bracket; the bolts pass through the through holes and are screwed onto the screw holes to fix the abutment plate to the positioning bracket.

[0012] The beneficial effects of the present invention are as follows:

[0013] According to the present invention, when the motor body is operated at high intensity, once the bolt becomes loose, the abutment plate and the positioning bracket become loose and vibrate. In this way, the abutment plate on the side of the loosened bolt vibrates more violently. Therefore, the induction spring column on the lower side of the violent vibration point expands and contracts most violently. Therefore, the corresponding pressure sensor sends a pressure signal to the controller, and the controller drives the corresponding power unit, so that the power unit drives the pressure rod at the corresponding position to press upward into the pressure groove, thereby achieving reinforcement of the vibrating part of the abutment plate, thereby achieving flexible monitoring, and improving the emergency flexibility and stability of the structure.
