This solution has number of drawbacks. Because screw/nut type efficiency is low, thereby need large for transmission devicePower electric motor is to guarantee the gratifying displacement of thrust terminator. In addition, because efficiency value is low, thereby this efficiency is easily subject to temperatureDegree, humidity, contact-making surface damage, lubricating quality is in time and the impact declining in transmission device. Finally, screw/nut type is notReversible, thus can there is the problem of secure context.
Summary of the invention
The present invention aims to provide a kind of transmission device for power train that makes up aforementioned disadvantages.
According to an aspect of the present invention, by means of a kind of transmission device for power train, the present invention can reach this object,Transmission device has:
-motor, it has rotor and stator, and rotor is fixed on drive surface and can be around rotation activity,
-multiple planetary roller, it has a surface, and surface structure becomes to coordinate with drive surface, so that surface is by described drivingWear moving and at least rotate around described axis, and
-thrust terminator, for power train, described thrust terminator has:
-driven surface, it is configured to coordinate with the surface of planetary roller, and
-bearing-surface, it is configured for breasting on power train, and bearing-surface can be with respect to driven surface activity.
According to the present invention, due to motor rotate the thrust terminator carrying out move need make middle planetary rolling member get involved. CauseThis, this transmission device uses planet rolling part formula leading screw, and its efficiency is because roller rolls and compares in drive surface and driven surfaceThe efficiency of screw/nut type system is higher.
In addition the speed reducing ratio that, this transmission device can have is also higher than the speed reducing ratio of transmission device that uses ball-screw.
In this transmission device, can relate to three from the rotor of motor to rotation-rectilinear motion conversion of thrust terminatorDifferent movable parts, that is: limit member, the Virtual Components being formed by whole planetary roller of drive surface and limit driven surfaceMember.
With respect to adopting the screwed standard roller of its outer surface, adopt its outer surface to there is groove line (stries)Planetary roller can allow the assembling of the different elements of simplifying transmission device. In fact, due to these screw threads, standard roller sameStep is essential, for example undertaken synchronously by gear, and in the time using planetary roller, not this situation.
Thrust terminator can have anti-rotation system, so that the rotor motion being transmitted by planetary roller makes thrust terminator only along rotorRotation carries out translation and moves. This anti-rotation system, for example by means of axial splines, especially forms with the housing of transmission deviceGuide groove connects.
The bearing-surface of thrust terminator can be axially and/or radially movable with respect to the driven surface of thrust terminator. In the application's meaningUnder, " radially " expression " in the plane vertical with the rotation of motor and along with the direction of this axes intersect ", " axially "Represent " being parallel to the rotation of motor ".
