Abstract
The present invention discloses a mechanical stepless speed change system based on gyroscopic effect, it is formed from a set of planetary gear train containing special gyro, and utilizes the constraining action of :submotion body" in the special gyro on the inertia dynamic state of gyro self-body revolution (or autorotation) to form a speed ratio variable power flow between the input shaft and output sahft so as to implement stepless speed change.
Description
The invention belongs to mechanical transmission fields.
In this field, the existing machinery stepless speed variator system can be divided into two big classes: promptly (1) utilizes the pulsed stepless speed variator system class of ratchet; (2) utilize the mill sassafras formula stepless speed variator system class of taper cone pulley.Last class is owing to the existence of pulsation, and application is narrow, is mainly used in the production line aspect; Back one class is owing to be subjected to the restriction of " skidding ", and unbearable important task is used also wideless.
The objective of the invention is: design and a kind ofly can overcome above-mentioned shortcoming, but the mechanical variable speed system of extensive use is realized the target that people dream of for a long time in the mechanical transmission fields.
The invention discloses a kind of mechanical variable speed system based on gyroscopic effect, it is made of the planet gear transmission system that a cover comprises special gyro, and it is characterized in that: special gyro has rotation, precession degrees of freedom concurrently in system; Special gyro is characterised in that the gyro body is with relative body movable it " sub-moving body ".Its working principle is: utilize the inertial force of " sub-moving body " in the special gyro to form the dynamic constrained that the rotation of gyro body in system, one degree of freedom in two rotational freedoms of revolution are formed, make to form the variable power circuit of speed ratio between the input shaft of planet gear transmission system and the output shaft, realize stepless change.
Beneficial effect of the present invention shows: if be applied to automobile, can save the trouble of gearshift; If be used for lathe, then can save often will be according to the inconvenience of depth of cut gearshift.Though, utilize hydraulics or electronic technology, also can satisfy requirement like this,, its Economy, reliability, and transmission efficiency but can't be equal to the present invention program.
Accompanying drawing is a schematic representation of the present invention.Among the figure, the 1st, input shaft, the 2nd, planet wheel, the 3rd, central gear, the 4th, output shaft, the 5th, special gyro, 5 ' be gyro it " sub-moving body ".As shown in the figure, rotative power from input shaft 1 input, can order about planet wheel 2 revolution, and because of the effect of output terminal loading moment, make planet wheel 2 rotations, the body that drives special gyro 5 produces the composite rotation of rotation and revolution, and bear " sub-moving body " 5 ' the put on inertia dynamic constrained moment of gyro body 5, the raising of restriction gyro 5 speed of autorotation, impel input power to do that speed adapts to load variations and the output that changes realizes the self adaption stepless change to output shaft 4 through planet wheel 2, central gear 3.
Most preferred embodiment of the present invention as shown in drawings, among the figure, the 1st, input shaft, the 2nd, planetary pinion, the 3rd, as the ring gear of central gear, the 4th, output shaft, the 5th, the special gyro body of employing low density aluminum alloy material or carbon fiber enhancement engineering plastic production, 5 ' be to be enclosed in a plurality of independent cavitys of gyro body interior, as the steel ball of " sub-moving body ".Owing to adopt gear transmission, can make transmission more reliable; Adopt low-density high-strength material gyro body, can reduce the invalid rotary inertia of gyro body relatively, the effect that improves effective rotary inertia of " sub-moving body " in the gyro improves the sensitivity that system's output speed changes automatically with load.
