Description
Technical field
The utility model relates to a kind of switching technique field, especially relates to a kind of accessory of ring main unit operating mechanism driver.
Background technology
Ring main unit operating mechanism driver is that occasions such as the automation, the low voltage electric network that are used for high-voltage fence and dual power supply drop into automatically, the network optimization provide power source.What present domestic most of switch cubicle adopted is first energy storage, and two steps of back combined floodgate (or separating brake) put in place.The operator of traditional ring main unit operating mechanism on-load switch and ground connection cutter are by an operator operating axis and ground connection operating axis is realized operating and the combined floodgate of ground connection cutter, there are two operation positions in its operating mechanism, promptly operate operation position and ground connection cutter operation position, general operation board by manpower rotary manipulation operator station or ground connection cutter station, through the energy storage of associated mechanisms parts driving spring, and then release can, thereby realize the branch of operator and ground connection cutter, the purpose of closing a floodgate, and a cover interlock must be installed between operator and the ground connection cutter, guarantee that operator and ground connection cutter can not close a floodgate simultaneously; It exists complicated operation, big, the not high shortcoming of Interlock Reliability of labour intensity, the more important thing is, can't realize remote operation.Along with development of electric power industry, can realize the on-load switch of power engineering automation and straighforward operation requirement and interlocking dependable performance, become people's eager desire.The on-load switch of existing ring main unit operating mechanism, though also can realize electronic and straighforward operation, for the drive that realizes motor with separate, clutch is installed on operating mechanism, but it exists the operating mechanism complexity of on-load switch again, and volume is big, and assembly difficulty is big, requirement is high, especially in course of action, still there is the impact shock factor, causes action to lack flatness; In addition, driver can not forward and backward, and what therefore adopt is first energy storage, and back (or separating brake) two steps of closing a floodgate put in place.
The utility model content
The purpose of this utility model is in order to solve above-mentioned the deficiencies in the prior art, a kind of clutch of ring main unit operating mechanism driver is provided, its clutch and motor driver are integrated, driver is except that the function that possesses clutch, can realize that it rotates and reverse, and assembling is easy, little, the stable action of impact shock.
The technical scheme that technical problem adopted that the utility model solves is:
The clutch of ring main unit operating mechanism driver is characterized in that comprising driving-disc, clutch deciliter piece, rotating shaft, pull bar, spring, push rod, and the outer ring of driving-disc is a gear, and the inner ring of driving-disc is with rotating shaft; The inner ring of clutch deciliter piece and rotating shaft splined; A clutch deciliter piece breadth is provided with and is fixed with ball set, and corresponding driving-disc breadth is provided with the suitable ball grooves of ball set; In the rotating shaft is circular cavity, is provided with push rod, spring in the rotating shaft, and the rotating shaft inwall of an end of spring is provided with locating ring, and the other end of spring withstands on the end of push rod; Push rod one end is provided with step, and the middle part is provided with groove; The groove and the rotating shaft inwall at push rod middle part form cavity; With the step of locating pin, push rod is located by rotating shaft and push rod; The outer end inner wall of clutch deciliter piece is provided with angle, the clutch deciliter corresponding rotating shaft in piece inwall angle place is provided with circular hole, is provided with a deciliter steel ball in the circular hole, and deciliter steel ball top withstands on the angle place of clutch deciliter piece inwall, the bottom withstands on the outer wall of push rod and the groove at push rod middle part communicates; Pull bar runs through in the middle of spring, the push rod, stretches out rotating shaft, and the pull bar end is rotary with nut.
Clutch deciliter piece breadth is provided with and is fixed with ball set is that even annulus is arranged, and the driving-disc breadth is provided with the even accordingly circumferential arrangement of the suitable ball grooves of ball set.
Above-mentioned deciliter steel ball has three, on three circular holes that nicely rounded ring arrangement rotating shaft is provided with.
Rotating shaft is arranged with bearing, so that be installed in the housing of driver.
The pull bar end is rotary with is rotary with nut, and available tapped Electric Machine Control shifting block replaces, and the motor of Electric Machine Control shifting block and driver can be realized interlock, when pull bar is pulled out, and the control shifting block assembly of Electric Machine Control shifting block by connecting, motor quits work.
Gear box is interior by gear drive (deceleration), according to ring main unit branch, combined floodgate requirement, but forward and backward.In initial condition, because spring heads on push rod, deciliter steel ball bottom withstands on the outer wall of push rod, deciliter steel ball top withstands on the angle place of clutch deciliter piece inwall, and the ball set of clutch deciliter piece breadth and the engagement of the ball grooves of driving-disc breadth are after the outer ring of driving-disc gear is driven, driving-disc rotates, clutch deciliter piece rotates simultaneously, because the inner ring and the rotating shaft splined of clutch deciliter piece, rotating shaft just realizes rotating.
When pull bar pulls outward, the nut of pull bar end withstands on the push rod end, the push rod extrusion spring, deciliter steel ball bottom enters the groove at push rod middle part and the cavity place that the rotating shaft inwall forms, the top of deciliter steel ball has broken away from the angle of clutch deciliter piece inwall, after the outer ring of driving-disc gear is driven, driving-disc rotates, because clutch deciliter piece does not have after the axial power, the ball set of clutch deciliter piece breadth and the ball grooves of driving-disc breadth separate at once, and a clutch deciliter piece just stops operating, and rotating shaft stops operating equally, driving-disc dallies in rotating shaft, and the clutch function just realizes.
Adopt the ball set of clutch deciliter piece and the ball grooves contact of driving-disc to realize the clutch function with separating, easy to control, torque is big, the life-span is long, is easy to centering, is easy to installation, and is easy to adjust; In addition, the clutch of its ball set and ball grooves, stationarity is good.
Engage and separate rapidly, clutch deciliter piece is under the effect of spring, and ball set number and ball grooves combination have reached the effect of effective buffering and vibration damping.
Deciliter steel ball balance the moment of torsion of clutch deciliter piece, guaranteed the stability of rotating shaft.
This driver adopts driven by motor change-speed gearing group, last gear of gear train and the gears engaged of driving-disc outer ring, just can realize the incorporate driver of motor and clutch, finish close, to be that driver is positive and negative transfer realization to separating brake, and the manual operation of consideration ring main unit operating mechanism or maintenance, maintenance also require driver that the function of clutch is arranged.That is: a, driver will be shown with forward and backward; B, driver will possess the function of clutch.By sprocket wheel, chain rotating Motion Transmission ring main unit operating mechanism, thereby reach separating brake, combined floodgate purpose.This structure can realize the energy storage combined floodgate, and the energy storage separating brake settles at one go.
The beneficial effects of the utility model are: the utility model is installed on the ring main unit operating mechanism driver, can realize the clutch function of driver and rotating and reverse of transmission, and stationary performance is good.
