The universal gear driving and speed-shifting mechanism mainly comprises a bearing (5), wherein a driving wheel (1), a driven wheel (2) and a bearing (5) are connected in turn. The universal gear driving and speed-shifting mechanism is mainly characterized in that plane geometry knowledge and solid geometry knowledge are combined, a plurality of special characters of circles, balls and ellipses are utilized to realize rotation on the space three-dimensional direction. The universal gear driving and speed-shifting mechanism has wide use, and is mainly applied in the fields such as automobile manufacture, robot manufacture, large-scale mechanical devices and the like.
Description
Technical field
The present invention relates to a kind of universal gear transmission and gear, more particularly, the present invention relates to gear transmission and rotate and speed change, it is used for transmitting rotation and energy; In transmittance process, rotatingshaft can be in the change of space any direction, and its maximum deflection angle is 120 degree.
Background technique
Now technology is used to change the non-gearing of the rotating shaft transferring rotational motion of angle.For known to the people being exactly universal joint, it is used to the wheel shaft of the live axle of automobile and axletree is coupled together this device.These universal joints are made into the form of classical two yoke forks (card is stepped on cardan) usually, and its structural table is shown two intersecting axles that interconnected by a pair of yoke fork.But the rotary speed unstabilization at the rotary course shaft is fixed.Thereby, people have developed constant speed (" CV ") type universal joint, in the universal joint of these types, tie point between the inclination rotating shaft is that the supply and demand by activity provide, drive and driven shaft every circle rotary course in, slide before and after in the track separately of these spin, thereby their center is remained in the plane at any time, the moment angle that forms between the diaxon is divided on this plane equally.But such CV universal joint is very complicated, its four lubricated comparatively difficulty, and in global automotive industry circle, the design of component and manufacturing are all thought most important widely on this universal joint.And very professional and advanced technology.Although the universal joint technology has obtained important development, it is expensive that its price remains, and universal joint comprises that blood makes difficulty more, expensive parts, and reason is and must enjoys grinding to very big surface with very high precision.This type of universal joint is being restricted aspect the rotating speed that it transmitted, more specifically, because the form of the point that adopts contact, and the slippage of rolling is quite big, so aspect the angle range that can work effectively, this type of universal joint is restricted.
Apart from modern, the invention of a lot of relevant spherical gears is arranged.These inventions mostly all are with solving the plane gear transmission mechanism of angle running to be arranged, and that is to say that these spherical gears can only realize that the angle of the plane space of two-dimensional coordinate changes, change at any angle that can not the implementation space three-dimensional.The universal joint of disclosed a kind of novel ball gear drive in No. 5613914 U. S. Patent, in this spherical gear driving mechanism, one of them gear is to have internal tooth, and another gear has external tooth.
Summary of the invention
The technical problem that this patent will solve relates to a kind of novel gear transmission mechanism, it is characterized in that: solve plane and space transmission; Can be widely used in the auto manufacturing, be used to replace universal joint, meanwhile also can applied robot's joint on.
