Abstract
The utility model relates to a friction planet transmission device which is a rotating movement device with certain transmission ratio which is transmitted by friction between rotating elements. The utility model is characterized in that an automatic locking mechanism is formed from three concentric cone chuck body star wheels 12, 14, 16, an outer rolling path 13 and a central small wheel 19 through a star wheel roller which is composed of a shaft 18 and steel balls 15. The utility model can automatically control the magnitude of frictional force during transmission process, prevent the generation of transmission and slide, and ensure the stability of a transmission operating system.
Description
The utility model relates to the transmission device that rotatablely moves that has fixed drive ratio with the friction driving between the rotatable member, and it is by body, tie-rod, bearing, formations such as axle star-wheel.
The existing mechanical transmission device generally adopts gear transmission, yet under high-speed condition, gear-driven noise is big, the required precision height of gear, thus manufacture cost is also high.The phenomenon of broken teeth in use still easily takes place.Friction planetary driving device up to now, in transmission process, often frictional force is difficult to control, needs artificial periodic adjustment, and device can't be regulated under motion state, in case skidding occurs, work system is just unstable, even transmission failure.
The purpose of this utility model is to overcome the deficiency of above-mentioned transmission device, and a kind of size that can control frictional force in the transmission process automatically is provided, and prevents the generation of transmission slip phenomenon, to guarantee the stable friction planetary driving device of transmission work system.
The measure that above-mentioned purpose reaches is: designed by the steel ball automatic locking mechanism that constituted of the planetary roller that is linked to be by axle of three concentric circular cone disk body star-wheels and outer raceway and central gear movingly.
Be further described below in conjunction with accompanying drawing:
The whole-cutaway view of Fig. 1, the utility model friction planetary driving device.
Fig. 2, be the A-A half sectional view of Fig. 1.
Accompanying drawing has been described the overall structure of friction planetary driving device.Support 1 links to each other with housing 11; Outer raceway 13 inwalls of ring have groove and inclined-plane, and being installed in can be along input in the housing 11, and the output shaft direction is regulated arbitrarily; Be equipped with on the wheel shaft 18 by steel ball 15 three planetary rollers that concentric circular cone disk body star-wheel 12,14,16 is formed movingly; Input shaft 3 one ends are by bearing 5 supportings, and the other end is the center steamboat 19 that has the inclined-plane; The lower edge of planetary roller contacts with center steamboat 19, and its upper edge has only star-wheel 12,16 to contact with outer raceway 13, and star-wheel 14 has groove and inclined-plane because of outer raceway 13, so be not in contact with it; Three concentric circular cone disk body star-wheels 12,14,16 are by steel ball 15 two junction plane places movingly, and its wheel body is milled with the end and is the vallecular cavity of wedge shape deeply, and steel ball 15 moves in its vallecular cavity; Axle 3, tie-rod 22, and the external part axle 23 of tie-rod 22 is added a cover end cap 10,8 formations one integral body again by bearing.According to actual needs, but in the friction planetary driving device design and installation three cover above by three concentric circular cone disk bodies by axle 18, planetary roller that steel ball 15 holds together and outer raceway.
Along with starting, the running of transmission device, when steel ball 15 three cylindrical cones to be locked when in aggregates, each contacting point all is a pure rolling; If external load changes, the contacting point then produces to skid and produces relative movement between three star-wheels that cause planetary roller, star-wheel 14 promptly is not subjected to outer carrying because of not contacting outer raceway 13, just can not produce yet and skid, the then relative star-wheel 14 with star-wheel 16 of star-wheel 12 relatively rotates, and moves in vallecular cavity thereby drive steel ball 15.Because the restriction of steel ball 15 groove cavity shapes, size, again star-wheel 12 is squeezed with star-wheel 16 and open, yet star-wheel is squeezed the restriction that the spacing of opening is subjected to the inclined-plane of outer raceway 3 and center steamboat 19 again, to star-wheel roller motion inevitable by outside raceway 13 and center steamboat 19 compress, increase frictional force, until produce enough frictional force with transmission when non-slip, relatively rotating just of star-wheel 12 and star-wheel 16 can stop, and at this moment star-wheel 12,14,16 forms an integral body again and does planetary motion.So the size of frictional force just can be regulated from motion tracking fully, reach and improve the stable purpose that reaches reliability of transmission.
