The present invention is that the off-axis problem of solution motor and the thorax problem of sweeping of motor provide a kind of method; This method is in buffer motor, to add flexible member or friction member; With flexible member or friction member system is cushioned; Promptly cushion to the moving component in the buffer motor and to the moving component in the buffer motor institute drive system, especially cushion, to solve the off-axis problem of motor with flexible member or friction member rotor to high speed rotating with flexible member or friction member; Thereby and the two ends that make stator and rotor all are supported the air gap of stator and rotor are guaranteed easily; Perhaps make the motor output element directly not be supported on the motor shaft; Bracing or strutting arrangement or casing by linking with frame/the earth support; The radial load perpendicular to motor output element live spindle direction that the motor output element is received is supported by motor case or bracing or strutting arrangement; Not to the motor shaft transmission, make stator and the air gap that is supported between the rotor on the motor shaft guarantees easily, solve the thorax problem of sweeping of motor; When system being cushioned with flexible member or friction member, can be divided into let between rotor and the motor shaft non-rigid connect and/or motor shaft and motor output element between non-rigidly connect and on motor shaft/rotor, add two kinds of flexible member/friction members; When between rotor and the motor shaft during non-rigid the connection, the motor output element can directly connect with motor shaft also and can connect with motor shaft through a plurality of elements; When between motor shaft and the motor output element during non-rigid the connection; Also can link between motor shaft and the motor output element through one or more elements; Here said element can comprise various deceleration components, acceleration components, shaft coupling and other required connection element; Deceleration component such as cylinder gear speed reducer, circular cone and circular cone and cylinder gear speed reducer, planetary gear speed-reduction, harmonic gear reducer, worm screw and gear and worm reducer, cycloidal-pin wheel decelerator or other decelerator; Shaft coupling can be various shaft couplings; But like friction coupling, spring coupling aligning poke-rod type shaft coupling, spring coupling can be a tyre coupling, the combination of just a kind of a plurality of or multiple a plurality of element connected in series of said here a plurality of elements and/or parallel connection; When on motor shaft/rotor, adding flexible member; Flexible member can act on the end of travel of one or several moving component in each moving component of buffer motor; The movement velocity that moving component can reduce moving component and associated part through compression or stretching to flexible member; Mainly can reduce the rotating speed of rotor and motor shaft; To solve the off-axis problem of motor, the flexible member here is mainly used in the absorption impact kinetic energy, and this paper is said, and flexible member is meant as long as flexible member can directly or indirectly just think that to motor shaft/rotor generation effect flexible member is added on motor shaft/rotor adding on motor shaft/rotor; When on motor shaft/rotor, adding friction member; Friction member acts on rotor or the motor shaft through intermediary element; When motor need pass through intermediary element not to rotor or motor shaft generation effect by friction member when system does work; When motor need be when system do work friction member through intermediary element to rotor or motor shaft generation effect or friction member through the partial journey generation effect of intermediary element to rotor or motor shaft; The rotating speed of rotor or motor shaft is reduced and be parked on the system desired position, intermediary element can be the various elements that include ratchet, detent mechanism; This paper said add on motor shaft/rotor friction member be meant if friction member can directly or indirectly just think that to motor shaft/rotor generation effect friction member is added on motor shaft/rotor.
The said motor shaft of this paper is meant the axle that is supporting rotor in the motor and the power of motor is outwards exported.
The element that the said motor output element of this paper is motor or the outside outputting power of buffer motor is like belt pulley, sprocket wheel, cam, crank, driving lever etc.
The said rotor of this paper is meant the parts that under the magnetic field force effect, rotate in the motor; Motor is accomplished motor through the rotation of rotor under the magnetic field force effect electric energy is converted into mechanical energy; Rotor and stator structure form and position can exchange, and every under the magnetic field force effect, the rotation makes the motor completion that those parts this paper that electric energy is converted into mechanical energy promptly is called rotor.
The non-rigid connection is meant that this non-rigid connection can accomplish the transmission of operation torque between rotor and the motor shaft between rotor and the motor shaft; If motor shaft is fixed; To rotor apply a moment or apply one increase to a certain value gradually moment; Rotate or rotating certain angle under the frictional resistance effect that rotor can produce at the elastic resistance or the friction member of flexible member generation, the angle of this rotation does not comprise the rotational angle that is caused by drive gap; Non-rigid between motor shaft and the motor output element connects and is meant that the non-rigid connection of this kind can accomplish the transmission of operation torque between motor shaft and the motor output element; If with the motor output element fixedly the time; To motor shaft apply a moment or apply one increase to a certain value gradually moment; Rotate or rotating certain angle under the frictional resistance effect that motor shaft can produce at the elastic resistance or the friction member of flexible member generation, this rotational angle does not comprise the rotational angle that drive gap causes; No matter between rotor and the motor shaft non-rigid connect still be motor shaft with the motor output element between non-rigid the connection; From rotor to all transmission links the motor output element; Has a link at least; Be to lean on the friction that produces between the elastic force that produces between flexible member and other element or friction member and other element to accomplish the transmission of power, or the transmission of completion power under the friction effect that produces between the elastic force/friction member that produces between flexible member and other element and other element; This paper said under the friction effect that produces between the elastic force that produces between flexible member and other element or friction member and other element transmission of completion power be meant that this elastic force or friction do not participate in the transmission of power directly; But the transmission of power be unable to do without this elastic force or friction; Like planetary reducer two output degrees of freedom are arranged; One degree of freedom is used for outputting power, and then another degree of freedom must be fixed, though be used for fixing the elastic force of this degree of freedom or the transmission that friction is not participated in power directly; But leave the transmission that this power just can't be accomplished power; And when in the transmittance process of power once there is big impulsive force to produce, if the frictional resistance effect rotation down that elastic resistance that this degree of freedom that is fixed can produce at above-mentioned flexible member or friction member produce is the degree of freedom that fixedly is fixed with flexible member; The kinetic energy that causes impulsive force will be absorbed by the form of flexible member with elastic potential energy; If with the degree of freedom that friction member fixedly is fixed, cause that the kinetic energy of impulsive force will be consumed by the form of the mutual friction between the friction member and the degree of freedom that is fixed with heating, protection system can not receive too big impulsive force; When motor shaft receives impulsive torque; More than two kinds of non-rigid connections all be that flexible member or friction member through non-rigid point of attachment absorbs the impact kinetic energy of rotor or system or consume; The impact kinetic energy that reduces rotor or system is to motor shaft or to the impact of system; Solve the suffered excessive problem of impulsive force of off-axis problem and system of motor, the said impulsive force of this paper comprise impulsive torque and and other impulsive force of causing by impulsive torque; Frictional resistance that the said friction member of the friction that produces between the said friction member of this paper and other element and this paper produces or friction all are meant the friction that produces between friction member and other element (other element is meant output degree of freedom of A end axle, planetary reducer or the like); When non-rigid connect and when taking rotor built-in between non-rigid connection the/motor shaft between rotor and the motor shaft and the motor output element; The two ends of rotor and stator can both be supported; Air gap between rotor and the stator is guaranteed easily; Not only solved the off-axis problem of motor but also solved the thorax problem of sweeping of motor, the built-in rotor that is meant of the said rotor of this paper is inboard at stator; When non-rigid connect and the motor output element directly is not supported on the motor shaft between motor shaft and the motor output element; But be supported on the motor case or the bracing or strutting arrangement that is supported on the time; The radial load that the motor output element receives is born by motor case or bracing or strutting arrangement; Not to the motor shaft transmission; The air gap that makes stator and be supported between the rotor on the motor shaft guarantees easily, motor shaft through spring coupling and/or friction coupling to motor output element transferring power, not only solved motor shaft because of the thorax problem of sweeping that receives radial load and cause and but also solved the off-axis problem of motor; The power that the radial load that the said motor output element of this paper receives is meant that the motor output element receives perpendicular to the live spindle direction of motor output element; In the composition of buffer motor or at buffer motor, in driven equipment power transmission process, use decelerator, output speed reduction, the output torque of motor are improved; As in planetary reducer and that degree of freedom of linking of motor output element be to lean on the elastic force of friction or elastomeric material between the abrasives to accomplish the transmission of moment of torsion in that a link is arranged in the process of motor output element power transmission; Promptly adopted non-rigid connection; Here said non-rigid connection is the same with aforementioned non-rigid connection principle, and that degree of freedom that is fixed so can rigidly fix also can be flexible fixing.
Said method is used for railway hump marshalling yard retarding device, railway hump marshalling yard parking apparatus, railway to hair line antiskid device, railway switch conversion equipment; Solved the impact of rotor to these equipment; This method solved the off-axis problem of the used motor of electric car retarder when being used for electric car retarder, solved again electric car retarder because of motor sweep that thorax causes do not alleviate problem; In the composition of motor or at motor, in driven equipment power transmission process, use decelerator; Improved the output torque of motor; The stopping power and the relief capabilities of electric car retarder have also been improved; Can accomplish smoothly under braking and the prerequisite of alleviating action satisfying car retarder, can reduce the number of the used motor of car retarder.
The present invention also provides two kinds of buffer motors; Wherein first kind of buffer motor comprises rotor; Motor shaft, motor output element etc., this buffer motor most important characteristic be exactly rotor with motor shaft between non-rigid connect and/or motor shaft and motor output element between non-rigid the connection, according to the difference of the non-rigid point of attachment of buffer motor; First kind of buffer motor can be divided into three major types, the characteristic of first kind buffer motor be rotor with motor shaft between non-rigid the connection; The characteristic of second type of buffer motor be motor shaft with the motor output element between non-rigid the connection; The characteristic of the 3rd type of buffer motor be rotor with motor shaft between also non-rigid connection between motor shaft and the motor output element non-rigid the connection time.
First kind buffer motor is except that comprising rotor, motor shaft, motor output element; Also comprise front end housing, rear end cap, body, stator, buffer etc.; The two ends that front end housing and rear end cap are separately fixed at fuselage form casing, rotor supports on motor shaft, when rotor when stator is inboard; Stator is fixed on the inner periphery of fuselage; When rotor was outside stator, stator was fixed on front end housing or the rear end cap, and the motor output element is fixed on that end that is in motor output end on the motor shaft; Buffer connects non-rigid connection the between completion rotor and the motor shaft in a circumferential direction with rotor and motor shaft; Do not having buffer to do the time spent, rotor can freely rotate on motor shaft, and said here freely the rotation is not to have no freely rotating of resistance; Say that just it is smaller that impulsive force that these resistances and system receive is compared; Could accomplish the mutual transmission of moment of torsion through buffer between rotor and the motor shaft,, can produce relative rotation or rotating certain angle between rotor and the motor shaft when the motor output element puts in place because of work or other reason when stopping operating suddenly; The rotational kinetic energy of rotor or other kinetic energy of system are stored in the flexible member of elastic buffer, or make rotor rotational kinetic energy or system other kinetic energy by the friction member in the buffer that rubs through and other element between each other friction consume with the form of heating; The said buffer of this paper is meant rotor and motor shaft linked up in a circumferential direction, accomplishes the transmission of the power between rotor and the motor shaft, and realizes non-rigid connection the between rotor and the motor.Cushioning principle according to buffer is different; Buffer can be divided into elastic buffer and two kinds in friction buffer, and the function of buffer is exactly to accomplish the transmission of operate as normal moment of torsion between rotor and the motor shaft, and when having impulsive torque to produce between rotor and the motor shaft; Elastic buffer fills to be permitted under rotor and the motor shaft elastic resistance effect that flexible member produces in elastic buffer; Through compression or tensile elasticity element, make to relatively rotate certain angle (not comprising the rotational angle that drive gap causes) between rotor and the motor shaft, the rotational kinetic energy of rotor or the kinetic energy of system are stored in the flexible member of elastic buffer; And the friction buffer is to increase to when the impulsive torque that produces between rotor and the motor shaft when filling the peak torque of being permitted transmission greater than the friction buffer; Rotor and motor shaft produce relative rotation under the frictional resistance effect of friction buffer friction member, the rotational kinetic energy of rotor or other kinetic energy of system are consumed, so buffer guarantees that motor shaft can not receive too big impulsive torque with the form of generating heat that rubs; Solved the off-axis problem of motor; If, make the two ends of rotor all be supported on the motor shaft realize between rotor and the motor shaft making the rotor of buffer motor built-in in non-rigid the connection with buffer; The two ends of stator all are supported on the casing; Air gap between rotor and the stator guarantees evenly easily like this, has so promptly solved the off-axis problem of motor, has solved the thorax problem of sweeping of motor again.
If regard rotor as axle a kind of, just a kind of shaft coupling of buffer, elastic buffer is exactly a spring coupling, and the friction buffer is exactly a friction coupling; This paper is called A end axle and B end axle respectively with two parts axis body of shaft coupling institute coupling spindle; Be called A end axle through the joining that part of axis body of friction member in friction and the friction coupling in two parts axis body that then friction coupling connected, be called B end axle through the joining that part of axis body of friction member in spline or flat key or other non-friction connecting mode and the friction coupling; So by this point-score, friction rotor and motor shaft that buffer connected, rotor and motor shaft that just friction coupling connected also can be called A end axle and B end axle, and both rotor was called A end axle, and motor shaft is called B end spool; Rotor that spring coupling connected and motor shaft equally also can be called A end axle with rotor, and motor shaft is called B end axle.If be motor shaft through the joining that part of axis body of friction member in friction and the friction coupling in two parts axis body that shaft coupling connected, rotor is called B end axle in this case, and motor shaft is called A end axle.
Elastic buffer is a spring coupling, and it comprises flexible member, and an effect end of flexible member directly or indirectly acts on the rotor, and another effect end directly or indirectly acts on the motor shaft, accomplishes the resilient connection between rotor and the motor shaft.So realize the transmission of operate as normal moment of torsion between rotor and the motor shaft through the elastic force that produces between flexible member and other element; When having impulsive torque to produce between rotor and the motor shaft; Rotor and motor shaft will relatively rotate certain angle, change the deflection act on flexible member between rotor and the motor shaft, and the kinetic energy of kinetic energy or the system of rotor is stored in the flexible member with the form of elastic potential energy; The protection motor shaft can not receive too big impulsive torque; Solved the off-axis problem of motor,, also solved motor simultaneously and swept the thorax problem if adopt rotor built-in.
The friction buffer is a friction coupling, and it comprises friction member, flexible member etc., friction member through flat key or spline or other method and B end spool be linked together; The attrition surface of the attrition surface of friction member and A end axle tightly forces together under the effect of flexible member; When the rotation of A end axle, the attrition surface of A end axle attrition surface through friction member under the friction effect drives the friction member rotation, and friction member drives B end axle and rotates; So pass through the transmission that friction realizes the operate as normal moment of torsion between A end axle and the B end axle; When having impulsive torque to produce between A end axle and the B end axle, and the impulsive torque that produces can transmit greater than friction coupling peak torque the time, the relative rotation that rubs of generation between the attrition surface of A end axle and the attrition surface of friction member; Under the frictional resistance effect; The kinetic energy of rotor or the kinetic energy of system are consumed with the form of friction heating, and protection motor shaft and system can not receive too big impulsive torque, have solved the off-axis problem of motor; If adopt rotor built-in, also solved motor simultaneously and swept the thorax problem.
Second type of buffer motor adopts non-rigid connection the between motor shaft and the motor output element; The non-rigid connection of this kind makes the motor output element directly not be fixed on the motor shaft; But accomplish the moment of torsion transmission between motor shaft and the motor output element through shaft coupling and/or decelerator; Because the motor output element directly is not fixed on the motor shaft, according to the fixing means of motor output element, second type of buffer motor is divided into two group buffer motors again; The motor output element of the first group buffer motor is supported by motor case; Shaft coupling and/or decelerator be in the interior of motor, and the motor output element of the second group buffer motor is to be supported by bracing or strutting arrangement, and shaft coupling and/or decelerator both can also can be outside at casing in interior.Motor case refers to containing the motor housing of rotor and stator.
The first group buffer motor in second type also comprises motor case, shaft coupling and/or decelerator except that comprising rotor, motor shaft, motor output element; The motor output element is supported on the motor case; Motor shaft through shaft coupling and/or decelerator and motor output element be linked together; And through shaft coupling and/or decelerator to motor output element output torque; Motor shaft is to realize through shaft coupling and/or decelerator with non-rigid connection between the motor output element; Wherein shaft coupling can be a spring coupling, also can be friction coupling, also can be cross groove shaft coupling; It also can be the combination of other various shaft couplings or other various shaft couplings; Wherein spring coupling is identical with the friction coupling action principle with spring coupling described in the first kind buffer motor with friction coupling, and wherein decelerator can be various forms of decelerators, like cylinder gear speed reducer, circular cone and circular cone and cylinder gear speed reducer, planetary gear speed-reduction, harmonic gear reducer, worm screw and gear and worm reducer, cycloidal-pin wheel decelerator or other decelerator; Wherein planetary reducer can be a differential teeth planetary gear reduction unit; Decelerator is with respect to friction coupling or spring coupling; Can be preposition also can be rearmounted; The input of decelerator and output can interrelate through various shaft couplings and other parts, and the cushioning effect of spring coupling or friction coupling has solved the off-axis problem of motor; Decelerator has reduced the rotating speed of buffer motor, has improved the output torque of buffer motor; The motor output element is supported by motor casing; The radial load that the motor output element is received is passed to the earth by motor casing, not to the motor shaft transmission, the rotor that is supported on the motor shaft and the air gap between the stator is guaranteed easily; Even and motor has and slightly sweeps the thorax phenomenon; Because motor shaft do not have the radial load effect, be supported between rotor and the stator on the motor shaft and also do not have too big active force, so also can not produce too big friction between rotor and the stator; Produce certain friction even that is to say the thorax of slightly sweeping because of motor; Since the friction that produces is too for a short time make the buffer motor output torque reduce not obviously, be not enough to influence the buffer motor operate as normal, solved the thorax problem of sweeping of motor so again; Be used for the hump yard motor vehicle and subtract device, promptly solved the off-axis problem of motor, solved the thorax problem of sweeping of motor again; Solved again simultaneously and swept the motor vehicle decelerator that thorax causes because of motor and do not alleviate problem; Owing to used decelerator in the buffer motor, reduced the rotating speed of buffer motor, improved the output torque of buffer motor; Braking and relief capabilities that motor vehicle subtracts device have also been improved; Subtract device and can accomplish under braking and the prerequisite of mitigation capability satisfying motor vehicle, can reduce the power of buffer motor, the minimizing motor vehicle subtracts the number of the required buffer motor of device.
The second group buffer motor in second type is except that comprising motor shaft, rotor, motor output element; Also comprise motor, bracing or strutting arrangement, shaft coupling and/or decelerator; Wherein motor shaft, rotor are two parts of motor, comprise motor (motor comprises motor shaft and rotor), motor output element, bracing or strutting arrangement, shaft coupling and/or decelerator so we can say the second group buffer motor in second type; Motor can be the nonstandard motor beyond standard electromotor or the standard, also can be torque motor, also can be other device that can electric energy be transformed mechanical energy; The motor output element is supported by bracing or strutting arrangement; The moment of torsion of motor output is passed to the motor output element by motor shaft through shaft coupling and/or decelerator, again by the motor output element to system's outputting power that buffer motor drove, motor shaft is to realize through shaft coupling and/or decelerator with non-rigid connection between the motor output element; Wherein shaft coupling can spring coupling; Also can be friction coupling, but also can be aligning poke-rod type shaft coupling that electricity can be the combination of various shaft couplings; The spring coupling here is identical with the friction coupling action principle with the spring coupling described in the first kind buffer motor with friction coupling; Wherein decelerator with second type in the first group buffer motor described in decelerator the same, can be decelerator of cylinder gear speed reducer, circular cone and circular cone and cylinder gear speed reducer, planetary gear speed-reduction, harmonic gear reducer, worm screw and gear and worm reducer, cycloidal-pin wheel decelerator or other form etc.; Planetary reducer can be a differential teeth planetary gear reduction unit; Because planetary reducer has an input, and output has two degrees of freedom, and the input of planetary reducer and spring coupling or friction coupling or other shaft coupling link, also can be directly or indirectly and motor link; Two degrees of freedom of its output; One of them degree of freedom and motor output element are directly or ask to connect and link to each other; To motor output element outputting power, another degree of freedom is fixed by flexibility, and flexible fixing branch resilient flexibility is fixed and rubbed flexible fixing two kinds; Make resilient flexibility fix when fixing one of the planetary reducer output degree of freedom, make the friction flexibility fix when fixing output degree of freedom of planetary reducer with friction member with flexible member; When having impulsive torque to produce between motor shaft and the motor output element; If flexibility fixedly is to adopt flexible member to fix; Flexible member produces distortion under the impulsive torque effect; Other kinetic energy of the rotational kinetic energy of rotor or system form with elastic potential energy is stored in the flexible member; Make between motor shaft and the motor output element and can not produce too big impulsive torque; If flexible fixing employing is friction member; When impulsive torque offered decelerator and is used for fixing the design peak torque of decelerator one degree of freedom greater than friction member, that degree of freedom that decelerator is fixed began to rotate under the friction effect that friction member provides, and the rotational kinetic energy of rotor and other kinetic energy in the system are consumed by the form of generating heat with mutual friction between friction member and other element; Thereby having guaranteed not have between motor shaft and the motor output element too big impulsive torque produces; Any in these two kinds of flexible fixing meanss all realized non-rigid connection the between motor shaft and the motor output element, be motor shaft with the motor output element between non-rigid another form that connects, the transmission of operate as normal moment of torsion must could be accomplished under the effect of the elastic force of this non-rigid point of attachment or friction between motor shaft and the motor output element; Buffer motor can adopt spring coupling and/or friction coupling to guarantee that motor shaft can not receive too big impulsive torque; Buffer motor also can adopt any in two kinds of flexible fixing meanss or two kinds to guarantee that motor shaft can not receive too big impulsive torque; Buffer motor also can adopt any in spring coupling and/or friction coupling and the two kinds of flexible fixing meanss or two kinds each other combination guaranteed that motor shaft can not receive too big impulsive torque; Simultaneously because the suffered radial load of motor output element can be to the motor shaft transmission; The rotor that is supported on the motor shaft and the air gap between the stator are guaranteed easily, solved the thorax problem of sweeping of motor, and because motor shaft does not receive the radial load effect; Even be supported on the slight thorax phenomenon of sweeping arranged between rotor and the stator on the motor shaft; Just can not produce too big friction yet, thereby both solve the off-axis problem of motor, solve the thorax problem of sweeping of motor again; The sort buffer motor is used for the hump yard electric car retarder, both solved the off-axis problem of motor, has also solved motor and has not alleviated problem because of the electric car retarder sweeping thorax and cause that the motor output torque seriously reduces to cause; If adopt decelerator in the structure of buffer motor, with second type in the same output torque that can improve buffer motor of the first group motor, reduce the power of buffer motor, reduce the number that motor vehicle subtracts the required buffer motor of device.
This paper is said flexible fixing to a planetary output free degree; Be meant in order to make a normal output torque of output free degree ability of planetary reducer; Must fix another output free degree of planetary reducer, and fixedly be flexible fixing this free degree; This paper will by flexibility fixedly the free degree be called drive end, flexible retaining element is called Partner, flexible retaining element can be that flexible member also can be a friction member; This to flexible fixing non-rigid connection of also having realized between motor shaft and the motor output element of one of planetary reducer output free degree; Be motor shaft with the motor output element between non-rigid connect a kind of; The non-rigid connection of this kind is not the transmission of directly accomplishing moment of torsion by the elastic force of friction between the abrasives or elastomeric material, but under the resilient force of friction between the abrasives or elastomeric material, accomplishes the transmission of moment of torsion; Based on this cardinal principle, can design various fixing means, with friction the one degree of freedom of planetary reducer being carried out flexibility fixedly is exactly wherein a kind of flexible fixed method; And with friction the one degree of freedom of planetary reducer is carried out that flexibility is fixing also can to have various forms; Wherein accent power friction pincers are exactly wherein a kind of, accent power friction pincers comprise hinge pin, friction pincers, transfer power element, flexible member etc., hinge pin to be fixed on the bracing or strutting arrangement or device that other and the earth link on; Two semicircle friction pincers are hinged on the hinge pin; Under the effect of transferring power element and flexible member, the opening of two circular friction pincers dwindles, and an output free degree of planetary reducer is held tightly; Through transferring the power element to change the size of flexible member deflection; With the size of adjustment flexible member, thereby change the size that produces friction between friction pincers and the planetary reducer, also just determined this flexibility fixedly to fill the size of planetary reducer output torque perhaps friction pincers active force; When the moment of torsion of planetary reducer output fills the peak torque of being permitted output greater than accent power friction pincers; Friction pincers can't be fixed an output free degree of planetary reducer, and this free degree is rotated down in the frictional resistance effect of friction pincers, thereby the form that other kinetic energy of the rotational kinetic energy of rotor or system generates heat with friction is consumed; Thereby guaranteed that motor shaft can not receive too big impulsive torque, solved the off-axis problem of motor.Accent power friction pincers are identical with jaw type friction coupling action principle, and with the rotation of axle that is connected, and the friction of accent power clamps and fixes the jaw type friction coupling in the buffer motor course of work.Planetary reducer used in the first group buffer motor in second type also can be used above-mentioned flexible fixation.
