Abstract
The present invention relates to a moment speed changer. Eight to sixteen moment variable diameter teeth with the tooth diameters decreasing uniformly are respectively arranged on a driving wheel and a driven wheel and slide in moment variable diameter grooves. Tension springs and pressure springs of a force accumulating mechanism are stressed to pull and press the moment variable diameter teeth, and corresponding moment variable diameter teeth are driven to be positioned in the moment variable diameter grooved according to stress intensity. Wind springs are utilized to control all the moment variable diameter teeth to shift synchronously, so that stepless moment speed change or multi-step moment speed change is realized.
Description
Technical field
The invention belongs to a kind of mechanical transmission, specifically is a kind of torque speed transmission that is used for the machine driven system of the big moment low speed starts of various needs such as various Motor Vehicle, heavy load winch, electric bicycle.
Background technique
At present, the mechanical transmission transmission technology at home and abroad all is a conventional art.The theoretical foundation of mechanical transmission speed change is by the amplifying moment that underspeeds, and realizes that the method for this purpose is a lot, as the drive wheel that adopts multi-stage gear or large speed ratio etc.Torque speed transmission is realized automatic stepless (or multistage) conversion rate, what effectively overcome the conventional machinery speed changer has level (4-6 level) speed change pattern, the labyrinth of automatically controlled hydraulic automatic speed variator, a low transmission moment of torsion shortcoming of metal band type stepless speed variator, have with the same stepless change ability of fluid torque converter the same adaptive rate performance, metal band type stepless speed variator, the high efficiency that conventional machinery formula speed changer is the same, also have that the other types speed changer do not have simple in structure, low-cost, can be applicable to the various occasions that need speed changer.
The objective of the invention is for the mechanical transmission speed variator system provide a kind of reliable, practical simple in structure, low-cost, can be applicable to various automatic stepless (or multistage) torque speed transmissions that need the speed changer occasion.
Summary of the invention
Torque speed transmission of the present invention, comprise driving wheel 1 and driven wheel 2 and power belt, all there are 8～16 teeth directly to be the descending balanced moment reducing tooth 4 that changes on driving wheel 1 and the driven wheel 2, moment reducing tooth 4 slides in the moment reducing teeth groove 8 on driving wheel 1 and the driven wheel 2, by the stressed pulling of holding force mechanisms extension spring 6 and stage clip 7 with press moment reducing tooth 4, drive corresponding moment reducing tooth 4 according to stressed size and in teeth groove 8, locate, by all moment reducing tooth 4 synchronous reducings of wind spring 5 controls.
Power belt of the present invention is a kind of toothed belt 3, the tooth footpath size variation that moment reducing tooth 4 on driving wheel 1 and the driven wheel 2 takes place is transmitted by toothed belt 3, all tooth pitches on the toothed belt 3 all equate, and the tooth pitch that should equate is identical with the tooth pitch in moment reducing tooth 4 minimum tooth footpath, and the number of teeth on the toothed belt 3 is far more than the number of teeth of moment reducing tooth 4.
Torque speed transmission of the present invention is work like this: power is transferred to driven wheel 2 spool 12 outputs by flute profile band 3 by 1 11 input of driving wheel after driving wheel 1 and driven wheel 2 moment conversion.Moment reducing tooth 4 is all arranged on driving wheel 1 and the driven wheel 2, realize automatic stepless (or multistage) conversion in moment and tooth footpath by moment reducing tooth 4.The tooth of the moment reducing tooth 4 of driving wheel 1 directly diminishes and the tooth of moment reducing tooth 4 on the driven wheel 2 directly becomes greatly during starting, by 3 transmission of flute profile band, thereby reaches the effect of amplifying moment.Moment reducing tooth 4 slides in the moment reducing teeth groove 8 on driving wheel 1 and the driven wheel 2, carries out the synchronous reducing of all moment reducing teeth 4 controls according to institute stressed size location and by wind spring 5 by holding force mechanisms extension spring 6 and stage clip 7.
Description of drawings
Fig. 1 is the design's a torque speed transmission principle assumption diagram.
Fig. 2 for moment reducing tooth 4, moment reducing teeth groove 8 on driving wheel 1 and the driven wheel 2, hold force mechanisms extension spring 6 and stage clip 7, control the cut away view of the wind spring 5 etc. of all moment reducing tooth 4 synchronous reducings.
Fig. 3 is the schematic representation of moment reducing teeth groove 8 and moment reducing tooth 4.
Embodiment
Present embodiment is equipped with 12 moment reducing teeth 4 on driving wheel 1 and driven wheel 2, moment reducing tooth 4 slides in the moment reducing teeth groove 8 on driving wheel 1 and the driven wheel 2, carry out radial location by holding force mechanisms extension spring 6 and stage clip 7 according to stressed size, and by wind spring 5 all moment reducing tooth 4 synchronous reducings of control.Moment reducing tooth 4 on driving wheel 1 and the driven wheel 2 is transmitted by flute profile band 3, tooth pitch during the tooth pitch on the flute profile band 3 and moment reducing tooth 4 minimum tooth footpath is identical, for ease of realizing stepless or multistage moment speed change, the number of teeth on the flute profile band 3 is far more than the number of teeth of moment reducing tooth 4, when moment reducing tooth 4 was not the minimum tooth footpath, flute profile band 3 was the engagements of part tooth with moment reducing tooth 4.Very big at starting period driving wheel 1 resistance during work, the tooth of the moment reducing tooth 4 of driving wheel 1 directly diminishes and the tooth of moment reducing tooth 4 on the driven wheel 2 directly becomes greatly, by 3 transmission of flute profile band, thereby reaches the effect of amplifying moment.Along with the resistance of the increase driving wheel 1 of speed reduces, the tooth of the moment reducing tooth 4 of driving wheel 1 directly becomes big and tooth moment reducing tooth 4 on the driven wheel 2 directly diminishes, and by 3 transmission of flute profile band, thereby reaches the effect of automatic raising speed.
This automatic stepless torque speed transmission of the present invention is reliable, practical, simple in structure, and low cost can be applicable to the various speed changer occasions that need.
