Specific embodiment
Below in conjunction with the accompanying drawings the present invention will be further described, and protection scope of the present invention is not limited to described below：
As shown in figure 1, a kind of belt pulley of manually adjustable pitch, it determines lid 1, band and moves in turn lid 2, knob 3 including belt wheel
With screw mandrel 4, the described band lid 2 that moves in turn is enclosed within belt wheel and determines on lid 1 and determine lid 1 with belt wheel to arrange in angle.As shown in figure 1, screw mandrel 4
The end of thread be connected with nut 5, be provided with rolling bearing A6 on nut 5, rolling bearing A6 is angular contact ball bearing, rolling bearing
The inner ring of A6 is fixed on nut 5, and the outer ring of rolling bearing A6 is fixed on band and moves in turn on the wheel hub of lid 2, and on nut 5 position is additionally provided with
Latch 7 outside band moves in turn lid 2.As shown in figure 1, two rolling bearing B8 are provided with the axle journal of screw mandrel 4, two rollings
Bearing B8 is 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
Determine on the wheel hub of lid 1.As shown in figure 1, being provided with knob 3 on the spindle nose of screw mandrel 4, stopper slot 9 is provided with the outer wall of knob 3,
The diameter of described latch 7 is slightly less than the groove width of stopper slot 9, and latch 7 is arranged in stopper slot 9 and can move along stopper slot 9
It is dynamic, when band move in turn lid 2 along belt wheel determine lid 1 to the left, move right when, latch 7 prevents band to move in turn lid 2 in moving process
Raw rotary motion, makes the band lid 2 that moves in turn move more steady and will not produce vibration.As shown in figure 1, rolling bearing A6 is arranged on rolling
Between bearing B8 and latch 7, latch 7 is arranged between rolling bearing A6 and knob 3.
Described band to move in turn and be provided with scale on lid 2, and the numerical value shown by scale is the pitch size of current belt wheel.
The course of work of the present invention is as follows：Two belt pulleys are extracted, V belt is installed between two belt pulleys, and
The belt wheel of any one belt pulley is determined into lid 1 to be connected with prime mover, starts prime mover, prime mover takes band to and moves in turn lid 2 and belt wheel
Lid 1 is determined while rotating.As depicted in figs. 1 and 2, when the load being carried on V belt increases, belt wheel is acted on
Tension force also increases on dynamic lid 2, and now, rotating forward knob 3 makes screw mandrel 4 rotate, and nut 5 does to the right on the bar of screw mandrel 4
Linear motion, nut 5 drives rolling bearing A6 and the band that is connected with the rolling bearing A6 lid 2 that moves in turn to move right, and three cuticles
Band to the axis direction that belt wheel determines lid 1 is moved, so that the pitch of belt pulley reduces, V belt determines lid 1 and belt wheel with belt wheel
The rotating speed of contact position is reduced between dynamic lid 2, effectively prevent that V belt and belt wheel determine lid 1 and band moves in turn the wear damage of lid 2, from
And extend the service life of belt pulley；When the load that is carried on V belt reduces, act on band move in turn on lid 2
Power also reduces, and now, rotating backward knob 3 makes screw mandrel 4 rotate, and nut 5 is doing the fortune of straight line to the left on screw mandrel 4
Dynamic, nut 5 drives rolling bearing A6 and the band that is connected with the rolling bearing A6 lid 2 that moves in turn to be moved to the left, and V belt to away from
Belt wheel determines the axis direction motion of lid 1, so that the pitch increase of belt pulley, V belt and belt wheel determine lid 1 and band moves in turn lid 2
Between contact position rotating speed increase, realize according to change loaded on V belt to manually change the section of belt pulley
Away from, to realize the adjustment of rotating speed, can be widely used for needing the occasion of stepless speed regulation, range of application is very wide.
The above is only the preferred embodiment of the present invention, it should be understood that the present invention is not limited to described herein
Form, is not to be taken as the exclusion to other embodiment, and can be used for various other combinations, modification and environment, and can be at this
In the text contemplated scope, it is modified by the technology or knowledge of above-mentioned teaching or association area.And those skilled in the art are entered
Capable change and change, then all should be in the protection domains of claims of the present invention without departing from the spirit and scope of the present invention
It is interior.
