Embodiment
Each component is used metal, rubber material manufacturing respectively among the present invention, and the skilled craftsman can be by Fig. 1-5 Assembling Production.The same rotation axis transmission principle that adopts with plane table thermoconductivity meter of the present invention, it has inherited all advantages of plane table thermoconductivity meter.When velocity ratio of the present invention was set at 5: 1, its working procedure was as follows: when the moment of torsion of gear shaft (1) input less than driving tep reel output shaft (27) required torque five/for the moment, planet gear stepless speed changer can not be worked, and remains static; The moment of torsion of importing when gear shaft (1) equals to drive tep reel output shaft (27) required torque five/for the moment, by gear (15), (18), (19), axle (8), (20), the planetary pinion assemblying body that pivoted arm (9), (22) constitute remains static, rotation is done in gear on the assemblying body (15), (18), (19), the reverse that pallet (3) and ring gear (13) work turn to respect to tep reel output shaft (27), at this moment tep reel output shaft (27) is by setting the velocity ratio output speed, gear shaft (1) and the rotating speed of tep reel output shaft (2 7) and the ratio maximum of moment of torsion; When the moment of torsion of gear shaft (1) input greater than driving tep reel output shaft (27) required torque five/for the moment, less than 1 o'clock, be used for acceleration greater than 1/5th less than 1 this part moment of torsion, be subjected to the effect of this part moment of torsion, the planetary pinion assemblying body begins to be changed into dynamically by static state, gear on the assemblying body (15), (18) (19) are in rotation, generation is the revolution at center around gear shaft (1) axis, pallet (3) and ring gear (13) are done corresponding deceleration and are reversed, stop to reverse, then with asynchronous coherent variation of rotating in the same way of tep reel output shaft (27), at this moment the rotating speed on gear shaft (1) and the tep reel output shaft (27) and the ratio of moment of torsion just produce continuous variation; When the moment of torsion of gear shaft (1) input equate with driving tep reel output shaft (27) required torque, when equaling 1, gear (15), (18), (19) stop rotation, planetary pinion assemblying body, pallet (3) and ring gear (13), tep reel output shaft (27) rotate synchronously with gear shaft (1), at this moment the rotating speed on tep reel output shaft (27) and the gear shaft (1) and the ratio minimum of moment of torsion, promptly 1: 1, so just realized stepless change.
