Accompanying drawing explanation
Fig. 1 is structural representation of the present invention;
Fig. 2 is that band of the present invention moves in turn and covers the structural representation that is moved to the left;
In figure, 1-belt wheel covers surely, and 2-is with the lid that moves in turn, 3-knob, 4-screw mandrel, 5-nut, 6-rolling bearing A, 7-stop pin, 8-rolling bearing B, 9-restraining groove.
Embodiment
Below in conjunction with accompanying drawing, the present invention will be further described, and protection scope of the present invention is not limited to the following stated:
As shown in Figure 1, a kind of can the belt pulley of manual tune pitch, it comprises, and belt wheel covers 1 surely, band moves in turn lid 2, knob 3 and screw mandrel 4, and the described band lid 2 that moves in turn is enclosed within belt wheel and surely covers on 1 and surely cover 1 with belt wheel and arrange in angle.As shown in Figure 1, the threaded end of screw mandrel 4 is connected with nut 5, nut 5 is provided with rolling bearing A6, rolling bearing A6 is angular contact ball bearing, the inner ring of rolling bearing A6 is fixed on nut 5, the outer ring of rolling bearing A6 is fixed on band and moves in turn on lid 2 wheel hub, nut 5 is also provided with the stop pin 7 being positioned at and being with lid 2 outside of moving in turn.As shown in Figure 1, the axle journal of screw mandrel 4 is provided with two rolling bearing B8, two rolling bearing B8 are deep groove ball bearing, and the inner ring of rolling bearing B8 is fixed on screw mandrel 4, and the outer ring of rolling bearing B8 is fixed on belt wheel and surely covers on the wheel hub of 1.As shown in Figure 1, the spindle nose of screw mandrel 4 is provided with knob 3, the outer wall of knob 3 is provided with restraining groove 9, the diameter of described stop pin 7 is slightly less than the groove width of restraining groove 9, stop pin 7 to be arranged in restraining groove 9 and can to move along restraining groove 9, when band move in turn lid 2 surely cover 1 left along belt wheel, move right time, stop pin 7 prevents the band lid 2 that moves in turn to rotate motion in moving process, makes the band lid 2 that moves in turn move more steadily and can not produce vibration.As shown in Figure 1, rolling bearing A6 is arranged between rolling bearing B8 and stop pin 7, and stop pin 7 is arranged between rolling bearing A6 and knob 3.
Described band moves in turn on lid 2 and is provided with scale, and the numerical value shown by scale is the pitch size of current belt wheel.
Working procedure of the present invention is as follows: extract two these belt pulleys, between two belt pulleys, v belt is installed, and the belt wheel of any one belt pulley is covered 1 be surely connected with prime mover, start prime mover, prime mover takes move in turn lid 2 and belt wheel of band to and surely covers 1 and rotate simultaneously.As depicted in figs. 1 and 2, when being carried in the load on v belt and increasing, act on the band tension force on lid 2 that moves in turn also to increase, now, rotating forward knob 3 makes screw mandrel 4 rotate, nut 5 does straight line motion to the right on screw mandrel 4 bar, nut 5 drives rolling bearing A6 and the band that is connected with rolling bearing A6 moves in turn, and lid 2 moves right, and v belt covers the axis direction motion of 1 surely to belt wheel, thus the pitch of belt pulley is reduced, v belt and belt wheel cover 1 and be with the rotating speed of contacting point between lid 2 that moves in turn to reduce surely, effectively prevent v belt and belt wheel surely cover 1 and band to move in turn lid 2 wear damage, thus extend the working life of belt pulley, when being carried in the load on v belt and reducing, act on the band tension force moved in turn on lid 2 also to reduce, now, rotating backward knob 3 makes screw mandrel 4 rotate, nut 5 is doing straight line motion left on screw mandrel 4, nut 5 drives rolling bearing A6 and the band that is connected with rolling bearing A6 moves in turn, and lid 2 is moved to the left, and v belt is to the axis direction motion of surely covering 1 away from belt wheel, thus the pitch of belt pulley is increased, v belt and belt wheel cover 1 and be with the rotating speed of contacting point between lid 2 that moves in turn to increase surely, achieve according to the change of load suffered on v belt manually to change the pitch of belt pulley, to realize the adjustment of rotating speed, the occasion needing stepless speed regulation can be widely used in, application area is very wide.
The above is only the preferred embodiment of the present invention, be to be understood that the present invention is not limited to the form disclosed by this paper, should not regard the eliminating to other embodiments as, and can be used for other combinations various, amendment and environment, and can in contemplated scope described herein, changed by the technology of above-mentioned instruction or association area or knowledge.And the change that those skilled in the art carry out and change do not depart from the spirit and scope of the present invention, then all should in the protection domain of claims of the present invention.
