Embodiment
For technological means, creation characteristic that the utility model is realized, reach object and effect is easy to understand, below in conjunction with concrete diagram, further set forth the utility model.
As shown in Fig. 1-6, vee belt stepless speed changes devices, it comprises: the benchmark V belt wheel 1 that is removably installed in running roller 6 end faces by bolt, it has the sleeve 10 that transmission shaft 5 is installed, in this sleeve, establish keyway 12(referring to Fig. 4), and transmission shaft has assembly flange structure 50, the wheel edge of described benchmark V belt wheel has a plane of inclination I11, adjustable ground is installed on the adjustable V belt wheel 2 at sleeve place, it is taken turns edge and has a plane of inclination II20 who coordinates with plane of inclination I and form belt mounting groove, the width of this belt mounting groove by notch towards bottom land diminish gradually (referring to Fig. 3), and this belt mounting groove is provided with the belt 4 being mated, what this belt was selected is structure wide at the top and narrow at the bottom, can be gapped between benchmark V belt wheel and adjustable V belt wheel time, move into and dwindle whole belt datum diameter, and when complete gapless time and retire to belt mounting groove and increase whole belt datum diameter between benchmark V belt wheel and adjustable V belt wheel, be sheathed on sleeve and be resisted against two collars 7 of adjustable V belt wheel, and two collars adopt arranged in dislocation, this collar arranges two can produce relative displacement while being convenient to regulate between benchmark V belt wheel and adjustable V belt wheel gap on sleeve.
Between described belt pulley I, II, distance regulating mechanism is installed, by distance regulating mechanism, Matching installation is become to large or diminishes in the belt datum diameter of belt mounting groove, this process can increase or reduce rotating speed.
Wherein, the bottom of the plane of inclination I of described benchmark V belt wheel and the plane of inclination II of adjustable V belt wheel all has step-like structure, and in the time that benchmark V belt wheel, II fit completely, the cross section of whole belt mounting groove is trapezium structure (shown in Figure 2).
Referring to Fig. 2, for coordinating the belt mounting groove of aforesaid trapezium structure, the cross section V-shaped (this vee-belt has equivalents with vee belt below) of described belt 4, in the time that between benchmark V belt wheel and adjustable V belt wheel, gap increases gradually, belt can be thereupon mobile toward the inside, gap, thereby reduce belt datum diameter.
Between described benchmark V belt wheel and adjustable V belt wheel, two locating studs that belt pulley is led 3 are installed, and locating stud is installed with symmetric mode.
Described distance regulating mechanism be multiple be installed on adjustable V belt wheel and can by adjustable V belt wheel top from or near the jackscrew 9 of benchmark V belt wheel, this jackscrew is sentenced annular array mode at V belt wheel and is provided with three.
Referring to Fig. 6, the figure shows the structure of collar, this collar can also be selected the locking jump ring of other structures.
The working principle of this case is:
In this structure, adjustable V belt wheel 2 is realized left and right movement by twisting jackscrew 9.
I), in the time need to improving the rotating speed of running roller 6, be with 2 to be moved to the left adjustable V by loose jackscrew 9.The end distance of two belt wheels (benchmark V belt wheel and adjustable V belt wheel) dwindles, and locating stud 3 play the guiding role vee belt 4 is moved outward.Increase the datum diameter of vee belt.And another diameter of vee belt immobilizes, therefore the velocity ratio of vee belt also increases, thereby improves the rotating speed of running roller.
Ii) in the time that needs are carried the rotating speed that reduces running roller 6, be with 2 to move right adjusting V by loose jackscrew 9.The end distance of two belt wheels increases, and locating stud 3 play the guiding role vee belt 4 is moved inward.Reduce the datum diameter of vee belt.And another diameter of vee belt immobilizes, therefore the velocity ratio of vee belt also reduces, thereby reduces the rotating speed of running roller.
The foregoing is only preferred implementation of the present utility model, protection domain of the present utility model is not limited in above-mentioned mode of execution, and every technological scheme that belongs to the utility model principle all belongs to protection domain of the present utility model.For a person skilled in the art, some improvement of carrying out under the prerequisite that does not depart from principle of the present utility model, these improve and also should be considered as protection domain of the present utility model.
