Abstract
The invention discloses a direct-current motor speed-limiting device for a simple glass edge finishing machine, relating to the technical field of auxiliary devices of glass edge finishing machines. The direct-current motor speed-limiting device is characterized in that a pair of fly weights with curved booms, a movable flat plate, a pressure spring, a fastening nut and a small shaft are sequentially arranged on a rotating shaft of a direct-current motor, and a limit switch used for controlling a power supply of the direct-current motor is arranged on the small shaft. The direct-current motor speed-limiting device has the advantages of compact structure, simpleness, reliability and easiness in operation and low cost.
Description
Technical field
The present invention relates to glass edge-grinding machine servicing unit technical field, particularly relate to a kind of DC motor speed-limiting device that is used for the simple glass edge polisher.
Background technology
In the prior art, be used for the series excitation type DC motor of simple glass edge polisher, when its output shaft resistance was big, exciting current increased, and power output/moment increases; During little or non-resistance, the rotating speed increase reaches commentaries on classics up to ten thousand sometimes, even " driving " when resistance.The easy like this motor rotor that causes damages serious mechanical accidents such as bearing destruction.The simple glass edge polisher receives the restriction of this technical barrier, can not shape up for a long time.
Summary of the invention
The objective of the invention is to overcome the deficiency of prior art, provide a kind of dc motor rotor that can limit unrestrictedly to raise, avoid the simple glass edge polisher of rotor and bearing damage to use the DC motor speed-limiting device.
Technical scheme of the present invention: in the rotating shaft of DC motor, set gradually a pair of flyball of curved boom, removable square position, stage clip, clamp nut and the little axle of being provided with, said little axle is provided with the limit switch of control power supply of dc motor.
Technique effect of the present invention is: compact conformation, simple and reliable easy row, cost are low.
Embodiment
Below in conjunction with accompanying drawing the present invention is elaborated:
Shown in accompanying drawing, among the figure: 1, little axle, 2, clamp nut, 3, stage clip, 4, the square position, 5, flyball, 6, limit switch, 7, bearing, 8, bearing box, 9, belt wheel, 10, body.
It sets gradually a pair of flyball of curved boom, removable square position, stage clip, clamp nut and the little axle of being provided with in the rotating shaft of DC motor, said little axle is provided with the limit switch of control power supply of dc motor.
When motor speed improved, flyball opened under action of centrifugal force, and the curved boom of flyball will head on the square position and move, thereby drove little axle.When rotating speed reaches certain numerical value, little axle will back down limit switch, and the lead of linking magnet exciting coil is broken off; Thereby cut off the passage of electric current, motor speed reduces, and the centrifugal of flyball reduces; Fastening nut closes up through stage clip and square position compressing flyball, and the square position reduces.Little axle return makes the switch contact point closed when the square position is reduced to certain position, and DC motor obtains electric energy, and rotating speed rises again.The rotating speed of motor maintains in certain scope again and again like this.
Flyball, square position, stage clip are installed on motor main shaft, are used the nut compressing stage clip; Little axle and limit switch are installed.When the position of switch is installed, must guarantee that flyball can make switch open and close flexibly in the range of speeds of regulation.
The rotating speed of regulating motor can pass through hold-down nut, and nut tightens motor speed downwards and heightens; Nut is turned down to raising loose motor speed.
