Abstract
The invention relates to a motor transmission mechanism, in particular to a gear transmission mechanism which is used for a high voltage switch cabinet and is used for controlling an earth switch to ground or switch out. The invention adopts the technical scheme that the gear transmission mechanism on the earth switch is characterized in that a fluted disc comprises an inner disc and an outer disc; the inner disc is arranged on an earth switch mounting shaft in a sleeving manner so as to be in fit with the mounting shaft in the circumferential direction; the outer disc is rotatably arranged on the inner disc; a pinball clamping position locking mechanism is arranged between the inner disc and the outer disc; a section of insection is arranged on the outer side surface of the outer disc; a concave part is arranged on each of the two sides of the insection. Through the adoption of the scheme, the gear transmission mechanism on earth switch overcomes the deficiency in the prior art, and the novel gear transmission mechanism on the earth switch provided by the invention can excellently control the earth switch to close or switch off, and cannot damage the gear or cause the motor to burn down when the motor is not in control.
Description
Technical field
The present invention relates to a kind of motor transmission mechanism, refer to be especially used in high-voltage switch gear cashier's office in a shop for controlling the gear drive of ground cutter ground connection or disconnection.
Background technique
In prior art, the combined floodgate of earthing and disconnection are divided into two kinds of situations, one is manually-operable, this mode is very common, also be a very conventional prescription formula, another kind is electronic mode, as the patent No. be 201220169326.3 the patent of " a kind of electric grounding knife-switch ", its earthing is by gear train engagement driving, machine operation can be controlled combined floodgate or the disconnection of earthing like this, the shortcoming of this mode is: mutually stressed with regard to easy destruction between gear in the time that motor is uncontrolled, the axle of earthing just cannot rotate after turning to combined floodgate or off position like this, gear train will damage or motor damage, so just easily there is security incident.
Summary of the invention
This is practical newly overcomes deficiency that prior art exists, and provides one to close a floodgate or to disconnect by fine operational grounding cutter, and in the time that motor is uncontrolled, can not destroy the gear drive on the novel earthing of gear or motor damage.
To achieve these goals, the present invention is by the following technical solutions: the gear drive on a kind of earthing, include earthing installation shaft, the first gear that is fixedly installed on the fluted disc in earthing installation shaft and rotates with active toothed disk, it is characterized in that: described fluted disc includes inner disc and outer disk, wherein inner disc is set in earthing installation shaft and with installation shaft and is circumferentially linked, described outer disk is rotating to be arranged on inner disc, between described inner disc and outer disk, be provided with hoodle screens locking framework, on the outer side surface of described outer disk, be provided with one section of groove, the both sides of this groove are provided with notch, on outer disk outer side surface, groove can engage with the groove on the first gear and form transmission cooperation, when hoodle in described hoodle screens locking framework locks with lockhole, the groove of the first gear engages with the gear in outer disk and drives outer disk to rotate, thereby outer disk drives inner disc to rotate is grounded the rotation of cutter installation shaft, the rear flank that described the first gear turns to outer disk groove is rotated further the hoodle disengaging lockhole that can make in hoodle screens locking framework, now thereby outer disk is rotated with respect to inner disc the groove of realizing the first gear and is proceeded in the notch of outer disk one side and dally.
By adopting such scheme, we can make the first gear driven outer disk rotate, thereby then driving inner disc rotation to be grounded cutter installation shaft by outer disk rotates, in addition when motor or its control switch go wrong cannot stop time, under the effect of power, can make hoodle depart from lockhole by the first gear of driven by motor, outer disk is just rotated with respect to inner disc like this, the groove of the first gear is proceeded in the breach of outer disk groove one side, the first gear is idle running just, can not damage like this groove, motor can not be subject to External Force Acting yet to be forced to stop burning, in the time that motor is normally worked, motor just automatically stops operating after ground connection cutter shaft disconnects or closes a floodgate, the first gear does not just need to proceed to breach idle running.
The further setting of the present invention is: on the side of described inner disc, be provided with fan-shaped bump, on the inner side of described outer disk, be provided with for the accommodating sector notch of fan-shaped bump, the radian of sector notch is greater than the radian of fan-shaped bump, described hoodle screens locking framework includes hoodle, lockhole and spring, wherein lockhole is arranged on the middle part of sector notch bottom surface radian direction, the middle part of the radian direction of described fan-shaped bump is provided with blind hole, spring and hoodle are successively set in blind hole, in the time that hoodle top is placed in lockhole, hoodle becomes lock state can realize the first gear with lockhole, outer disk and inner disc synchronously rotate, when turning to inner disc and cannot rotating, hoodle departs from lockhole, outer disk is rotated and is made the respective side of sector notch one side and inner disc fan-shaped bump conflict spacing, now the groove of the first gear just proceeds to and in the notch of outer disk groove one side, realizes idle running.
By the scheme of further setting, by the position of sector notch and fan-shaped bump and big or small setting, we can make the first gear both can dally in breach, prevent that groove from damaging and burn-down of electric motor, can make again after the first gear counter-rotation can also recover the engagement of outer disk groove to work on and drive earthing to close a floodgate or disconnect.
Of the present invention further setting is again: the indentation, there of described outer disk groove both sides is respectively arranged with shell fragment, shell fragment is fixedly installed on indentation, there, one end perk of shell fragment, shell fragment perk end forms the end tooth of outer disk groove respective ends, when the first gear turns to indentation, there and is rotated further, the first gear can press down shell fragment and realize idle running, the first gear turns to after indentation, there idle running counter-rotation again, and the first gear can recover to engage with outer disk groove by shell fragment.
By the above-mentioned further plan of establishment, after we can well ensure that the first gear dallies in breach by shell fragment, the first gear counter-rotation can also recover the engagement of outer disk groove to work on and drive earthing to close a floodgate or disconnect, because shell fragment has flexiblely, so pressing down shell fragment in when idle running, the first gear can not damage groove in addition.
Newly be described in further detail originally practical below in conjunction with accompanying drawing.
