Axle 8 is connected on pedestal 1 with revolute pair form, and driven pulley 10 is fixed on axle 8, and transducer 9 is fixed on driven pulley 10, and therefore transducer 9 can rotate around the axis of axle 8.
As shown in Figures 2 and 3, driving shaft 7 and driven pulley 10 are linked together by rope 11 and rope 12.For ease of statement, agreement: positive direction be parallel to driving shaft 7 axis and also from 7b position, sensing hole, 7a position, hole, otherwise be negative direction.Hold driving shaft 7 with the right hand, thumb direction is identical with positive direction, then the direction of all the other four fingers is along pointer direction, otherwise is counterclockwise.The winding direction of rope 11 is pressed from the initial direction to dop 11b, dop 11a one end as a reference, and the winding direction of rope 12 is pressed from the initial direction to dop 12b, dop 12a one end as a reference.As do not made specified otherwise, " positive direction ", " negative direction ", " clockwise " that hereafter occur, " counterclockwise " and rope are around to all to be defined as basis of reference herein.
One end of rope 11 through driving shaft 7 hole 7a and dop 11a is stuck in the oral area of the hole 7a of driving shaft 7.The other parts of rope 11 leave driving shaft 7 surface after the surface of driving shaft 7 is wound around certain length in the direction of the clock, then press wrapped anti-clockwise certain length on the surface of driven pulley 10, then rope 11 through driven pulley 10 slit 10a and dop 11b is stuck in the breach 10b place of driven pulley 10.Therefore, the two ends of rope 11 are all fixed, and when driving shaft 7 is rotated counterclockwise and rope 11 is in tensioned state, rope 11 pulls driven pulley 10 to turn clockwise.
One end of rope 12 through driving shaft 7 hole 7b and dop 12a is stuck in the oral area of the hole 7b of driving shaft 7.The other parts of rope 12 leave driving shaft 7 surface on the surface of driving shaft 7 after being counterclockwise wound around certain length, then press wound clockwise certain length on the surface of driven pulley 10, then rope 12 through driven pulley 10 breach 10c, slit 10d and dop 12b is stuck in the breach 10e place of driven pulley 10.Therefore, the two ends of rope 12 are all fixed, and when driving shaft 7 turns clockwise and rope 12 is in tensioned state, rope 12 pulls driven pulley 10 to be rotated counterclockwise.
In order to reduce the rotary inertia of driven pulley 10, driven pulley 10 forms groove 10f, the part of rope 12 between the breach 10c and slit 10d of driven pulley 10 is unsettled.
In order to ensure that rope 11 and rope 12 are in lasting tensioned state, in drive system, introduce flexible member.Respectively there is a hook ring at the two ends of extension spring 13, and one end hook ring hooks on rope 12, and other end hook ring hooks on the pin 14 be fixedly connected with driven pulley 10.The application point of hook ring and rope 12 is on the pendulous tank between the breach 10c of driven pulley 10 and slit 10d.Pin 14 can adopt thread connecting mode with the connected mode of driven pulley 10, and other modes also can be adopted to connect.The extension spring 13 acting on rope 12 with other flexible members as replacements such as Compress Spring, torsionspring, shell fragments, only can need make adaptability revision in syndeton.
First example structure is simple, and it is little to take up room.Wherein there is pendulous tank at least one rope on the driven wheel, except reducing driven pulley rotary inertia, also the connection of flexible member and rope is facilitated, by the tensile force effect that the flexible member being connected to driven pulley produces rope, make rope continue to keep tensioned state, the transmission making driving shaft drive transducer to rotate can steadily be carried out all the time.
In the present embodiment, determine in the fixed position, two ends of rope 11 and rope 12, spring 13 drift is when determining, the length of rope 11 and rope 12 is sufficiently accurate, the elongation that guarantee installs rear spring 13 changes in a little scope, also can not be too little to ensure that the power of tightening of rope 11 and rope 12 is not too large.
In actual process, the length of rope 11 and rope 12 is difficult to accomplish that enough accurately this often causes the power of tightening of rope 11 and rope 12 too large or too little, is difficult to regulate.In order to make the adjustment of rope more flexible, be not limited to rope lengths, introduce adjustment structure in the examples below, make to ensure when the length of rope 11 and rope 12 cannot accurately control the power of tightening of rope 11 and rope 12 one among a small circle in change.Particularly, connect an adjustment pin on the driven wheel, one end of a wherein rope is fixed in adjustment pin and a part of length is wrapped in connection adjustment pin realizing this rope and driven pulley, the length of such rope can regulate within the specific limits, in addition, rear to the rotation of adjustment pin generation active force drive adjustment pin in order to prevent rope from tightening, the rotation-preventing mechanism preventing adjustment pin from rotating accordingly is set in addition, illustrates to the 6th embodiment below by way of the second embodiment.
Second embodiment
As shown in Figure 4 and Figure 5, rope 12 is wound around certain length and through the breach 10c of driven pulley 10 on driven pulley 10, then through adjustment pin 15 slit 15a and dop 12b is stuck in the U-shaped breach 15b place of adjustment pin 15.Adjustment pin 15 has left hand thread structure 15c and coordinates with the screwed hole 10g of driven pulley 10, and adjustment pin 15 also has right-handed thread structure 15d.The screw thread boundary section 15e of adjustment pin 15 is between the left hand thread structure 15c of adjustment pin 15 and right-handed thread structure 15d.The right-handed thread structure 15d of adjustment pin 15 is exposed to the surface of driven pulley 10 and is threaded with the screwed hole 16a of nut 16.One end hook ring of spring 13 hooks and is on the pendulous tank between the breach 10c of driven pulley 10 and adjustment pin 15 at rope 12, and other end hook ring catches on the pin 14 be fixed on driven pulley 10.
During operation, the two ends of rope 11 have been fixed and have correctly been wrapped on driving shaft 7 and driven pulley 10 according to preceding method, and the dop 12a of rope 12 is fixed on driving shaft 7 and according to preceding method and is correctly wrapped on driving shaft 7 and driven pulley 10.First by adjustment pin 15 left hand thread engagement on driven pulley 10, reserved certain length of fit.Now, the right-handed thread structure 15d of adjustment pin 15 is exposed to driven pulley 10 surface, and be coupled in adjustment pin 15 by nut 16 right-handed thread, but do not tighten, when adjustment pin 15 is rotated, nut 16 can rotate together.Rope 12 through the breach 10c of driven pulley 10, then through adjustment pin 15 slit 15a and dop 12b is stuck in the U-shaped breach 15b place of adjustment pin 15.Then the two ends of spring 13 are hooked respectively on being between the breach 10c of driven pulley 10 and adjustment pin 15 at rope 12 pendulous tank and on pin 14.Now, be rotated counterclockwise adjustment pin 15 and a part of length of rope 12 be wrapped in the surface of adjustment pin 15, the fastening nut 16 when the rate of tension of rope 12 reaches requirement, makes the end face of nut 16 and driven pulley 10 fit.
Suffered by adjustment pin 15, the active force of rope 12 is clockwise torsional moment, when adjustment pin 15 rotates an angle in the tensile force clockwise under influence direction of rope 12, the helicitic texture 15c of adjustment pin 15 exits certain length from the levogyrate inner thread hole 10g of driven pulley 10, and namely the helicitic texture 15c of adjustment pin 15 moves a certain distance along negative direction.Due to adjustment pin 15 with nut 16 for right-handed thread coordinates, therefore adjustment pin 15 turns clockwise certain angle, and the helicitic texture 15d of adjustment pin 15 is relative to nut 16 precession certain length, and namely the helicitic texture 15d of adjustment pin 15 moves a certain distance along positive direction.Therefore, the screw thread boundary section 15e of adjustment pin 15 must stretcher strain certain length.After adjustment pin 15 turns over certain angle clockwise, adjustment pin 15 stretcher strain becomes large, and the resistance that adjustment pin 15 rotates clockwise also can become large, is therefore more difficult to rotate clockwise, and namely diminish can be more difficult for cord tightness degree.Such rope solderless wrapped connection one segment length in adjustment pin, then by the helicitic texture of adjustment pin and driven pulley, nut coordinate the rotation-preventing mechanism forming and prevent adjustment pin from rotating, the elasticity of rope can be controlled more neatly.
If the helicitic texture 15c of the adjustment pin 15 and screwed hole 10g of driven pulley 10 coordinated with it is right-handed thread, the helicitic texture 15d of the adjustment pin 15 and screwed hole 16a of nut 16 coordinated with it is left hand thread, rope 12 is wound around clockwise in adjustment pin 15, when adjustment pin 15 rotates counterclockwise an angle under the active force of rope 12, the helicitic texture 15c of adjustment pin 15 moves a certain distance along negative direction, the helicitic texture 15d of adjustment pin 15 moves a certain distance along positive direction, the screw thread boundary section 15e of adjustment pin 15 also can be subject to stretching action, the effect stoping cord tightness degree to diminish can be reached equally.
In the present embodiment, two helicitic texture rotation directions of adjustment pin are contrary, the mobile trend of two helicitic textures is contrary, as long as can ensure under the effect of rope active force, two opposing motions of helicitic texture of adjustment pin, make the boundary section Tensile between two helicitic textures, and ensure that nut end face is fitted in driven pulley surface always, can reach and prevent adjustment pin from rotating and keeping the object of cord tightness degree.In actual applications, the relative position of two thread rotary orientations, nut and driven pulley and rope in adjustment pin around to the factor for being associated, by the opposing motion of regulating guarantee two screw thread of each factor.
In above-mentioned example, the helicitic texture 15c of adjustment pin 15 coordinates with the screwed hole 10g of driven pulley 10, helicitic texture 15d coordinates with the screwed hole 16a of nut 16; And if the helicitic texture 15c of adjustment pin 15 coordinates with the screwed hole 16a of nut 16, the helicitic texture 15d of adjustment pin 15 coordinates (relative position namely changing driven pulley and nut) with the screwed hole 10g of driven pulley 10, by regulate two helicitic texture rotation directions and rope around to also reaching identical effect.
As, the helicitic texture 15c of adjustment pin 15 is left hand thread, and helicitic texture 15d is right-handed thread, and rope 12 is wrapped anti-clockwise in adjustment pin 15.Adjustment pin 15 is by clockwise active force, and the helicitic texture 15d due to adjustment pin 15 is right-handed thread, and therefore the helicitic texture 15d of adjustment pin 15 has the trend along positive direction movement; Helicitic texture 15c due to adjustment pin 15 is left hand thread, and therefore the helicitic texture 15c of adjustment pin 15 has the trend along negative direction movement.This can cause the screw thread boundary section 15e place structure of adjustment pin 15 to be subject to stretcher strain, which increases the resistance that adjustment pin rotates clockwise, and reaches the effect stoping cord tightness degree to diminish.In like manner, the helicitic texture 15c of adjustment pin 15 is right-handed thread, and helicitic texture 15d is left hand thread, the wound clockwise of rope 12 in adjustment pin 15, also can reach the effect stoping cord tightness degree to diminish.
3rd embodiment
The present embodiment is substantially identical with the second example structure, and difference is that the rotation direction of two sections of screw threads in adjustment pin is identical, and thread pitch is different.
Consult Fig. 4 and Fig. 5 equally, helicitic texture 15c and the helicitic texture 15d of adjustment pin 15 are left hand thread, and the pitch of helicitic texture 15c is greater than the pitch of helicitic texture 15d.The helicitic texture 15c of adjustment pin 15 and the screwed hole 10g threaded engagement of driven pulley 10, the helicitic texture 15d of adjustment pin 15 and the screwed hole 16a threaded engagement of nut 16.Rope 12 is wrapped anti-clockwise in adjustment pin 15, and adjustment pin 15 has the trend rotated clockwise under rope 12 active force, and the helicitic texture 15c of adjustment pin 15 and helicitic texture 15d all has the trend along negative direction movement.Pitch due to the helicitic texture 15c of adjustment pin 15 is greater than the pitch of helicitic texture 15d, the helicitic texture 15c of adjustment pin 15 is greater than the speed of helicitic texture 15d along negative direction movement, i.e. the screw thread boundary section 15e Tensile of adjustment pin 15 along the speed of negative direction movement.Adjustment pin 15 rotates clockwise the stretcher strain of the screw thread boundary section 15e that must overcome adjustment pin 15, is therefore more difficult, this guarantees adjustment pin 15 and is difficult to rotate clockwise, and reaches the effect stoping cord tightness degree to diminish.
If the helicitic texture 15c of adjustment pin 15 and helicitic texture 15d is right-handed thread, the pitch of helicitic texture 15c is greater than the pitch of helicitic texture 15d, rope 12 is wound clockwise in adjustment pin 15, adjustment pin 15 has the trend rotated counterclockwise under the active force of rope 12, and the helicitic texture 15c of adjustment pin 15 and helicitic texture 15d has the trend along negative direction movement.Pitch due to the helicitic texture 15c of adjustment pin 15 is greater than the pitch of helicitic texture 15d, therefore the helicitic texture 15c of adjustment pin 15 is greater than the speed of helicitic texture 15d along negative direction movement along the speed of negative direction movement, the i.e. screw thread boundary section 15e Tensile of adjustment pin 15, which increase the difficulty that adjustment pin 15 rotates counterclockwise, also can reach the effect stoping cord tightness degree to diminish.
In above-mentioned example, nut 16 punishes the both sides of listing in driven pulley 10 with rope solderless wrapped connection in adjustment pin 15, and adjustment pin 15 is first connected with nut 16 through driven pulley 10 again.If but the helicitic texture 15c of adjustment pin 15 coordinates with the screwed hole 16a of nut 16, the helicitic texture 15d of adjustment pin 15 coordinates (relative position namely changing driven pulley and nut) with the screwed hole 10g of driven pulley 10, helicitic texture 15d pitch is greater than helicitic texture 15c pitch, nut 16 end face is made to be fitted on the surface of driven pulley 10 equally, then by rationally arranging thread rotary orientation and rope reaches identical effect around Xiang Yike.
Such as, when the helicitic texture 15c of adjustment pin 15 and helicitic texture 15d is right-handed thread, by rope 12 along wrapped anti-clockwise.Under the effect of rope 12 active force, adjustment pin 15 has the trend rotated clockwise, the helicitic texture 15c of adjustment pin 15 and helicitic texture 15d all has the trend along positive direction movement, but the speed of helicitic texture 15c movement is less than the speed of helicitic texture 15d movement, i.e. screw thread boundary section 15e place Tensile, which increase the difficulty that adjustment pin 15 rotates clockwise, reach the effect stoping cord tightness degree to diminish.Equally, when helicitic texture 15c, 15d are left hand thread, by rope 12 along wound clockwise, also identical effect can be reached.
Generally speaking, in the present embodiment, the pitch of the helicitic texture that adjustment pin 15 is coordinated with driven pulley 10 is only needed to be greater than the pitch of the helicitic texture of adjustment pin 15 and nut screw connection, the surface of nut 16 end face laminating driven pulley 10, and under the effect of rope active force, the direction that the moving direction of adjustment pin 15 and the laminating end face (end face of namely fitting with driven pulley, lower same) of nut 16 point to the coating surface (surface of namely fitting with nut, lower same) of driven pulley 10 is identical.
4th embodiment
4th embodiment is substantially identical with the second example structure, and difference is that nut 16 is fixedly connected with adjustment pin 15.Still consult Fig. 4 and Fig. 5, the helicitic texture 15c of adjustment pin 15 is left hand thread, coordinates with the screwed hole 10g of driven pulley 10.The helicitic texture 15d of adjustment pin 15 coordinates with the screwed hole 16a of nut 16.Nut 16, in adjustment pin 15, when the elasticity of rope 12 reaches requirement, is tightened with adjustment pin 15 threaded engagement by rope 12 wrapped anti-clockwise, and adopts the modes such as bonding, welding nut 16 and adjustment pin 15 to be fixed together.Under the active force effect of rope 12, adjustment pin 15 has the trend rotated clockwise, and adjustment pin 15 has the trend along negative direction movement.But to be fixedly connected with adjustment pin 15 due to nut 16 and the end face of nut 16 is pressed on the surface of driven pulley 10, the therefore screw thread boundary section 15e Tensile effect of adjustment pin 15.Which increase the difficulty that adjustment pin 15 rotates clockwise, the effect stoping cord tightness degree to diminish can be reached.
If the helicitic texture 15c of adjustment pin 15 is right-handed thread, rope 12 is wound clockwise in adjustment pin 15, and nut 16 coordinates with adjustment pin 15 and fixes.Adjustment pin 15 has the trend rotated counterclockwise under rope 12 active force, the helicitic texture 15c of adjustment pin 15 has the trend of negative direction movement, due to the barrier effect of nut 16, the screw thread boundary section 15e Tensile effect of adjustment pin 15, increase the difficulty that adjustment pin 15 rotates clockwise, the effect stoping cord tightness degree to diminish can be reached.
Nut 16 also can replace with common fixed block, directly bonding or weld with adjustment pin 15, correspondingly, adjustment pin 15 can not arrange helicitic texture 15d, as long as enable fixed block reach fixing with adjustment pin 15 and fixed block end face is pressed on driven pulley 10 surface.
In the present embodiment, fixed block and adjustment pin are fixed, and the end face of fixed block is pressed on driven pulley on the surface.Under the effect of rope active force, the moving direction of adjustment pin and the part of driven pulley threaded engagement and fixed block are fitted, and to point to the direction of driven pulley coating surface identical for end face, part fixing with fixed block in adjustment pin cannot move, make the effect of adjustment pin last separation structure Tensile, therefore adjustment pin is difficult to mobile, reaches and prevents adjustment pin from rotating the object changing cord tightness degree.Fixed block and the rope winding position in adjustment pin can be respectively in driven pulley both sides, also can at homonymy.
5th embodiment
As shown in Figure 6, the 5th embodiment is substantially identical with the second example structure, is equally also to introduce adjustment pin 15 for solderless wrapped connection one section of rope, and difference is do not have nut 16, but increase compression pin 17 plays the effect preventing adjustment pin 15 from rotating.
In the present embodiment, adjustment pin 15 has left hand thread structure 15c and coordinates with the screwed hole 10g of driven pulley 10.Adjustment pin 15 1 end faces are called end face A, and other end is called end face B, and the direction pointing to end face B from end face A is identical with the direction that adjustment pin 15 screws relative to driven pulley 10.Compress pin 17 and have flange 17a, when after adjustment pin 15 with driven pulley 10 threaded engagement, the flange 17a compressing pin 17 is pressed on the end face A of adjustment pin 15, and is fixed on driven pulley 10 by compression pin 17.Rope 11 is identical with the second embodiment with the installation method of rope 12.During operation, be first rotated counterclockwise adjustment pin 15 to adjust cord tightness degree, when cord tightness degree reaches requirement, the flange 17a compressing pin 17 be pressed on the end face A of adjustment pin 15 and fixed by compression pin 17.Compress fixing of pin 17 and driven pulley 10 and can adopt methods such as welding, rivet, be bonding.
Under the active force effect of rope 12, adjustment pin 15 has the trend rotated clockwise, adjustment pin 15 has the trend along negative direction movement, but because the flange 17a compressing pin 17 is pressed on the end face A of adjustment pin 15 and stops adjustment pin 15 to move along negative direction, therefore adjustment pin 15 is difficult to rotate clockwise, and reaches the effect stoping cord tightness degree to diminish.
More than adopt to compress the embody rule scheme of pin 17 as rotation-preventing mechanism, but compress the selection of adjustment pin 15 end face of pin upper flange 17a laminating, rope around to, the helicitic texture rotation direction that adjustment pin 15 coordinates with driven pulley 10 is inter-related, the change of a factor coordinates by organic association of other factors the object reaching anti-rotation, as long as can ensure under the active force effect of rope 12, compress pin 17 and stop that adjustment pin 15 moves the effect that can reach and stop cord tightness degree to diminish, it will be intended to: compress pin and be fixedly connected with driven pulley, compress to sell to be fitted on the surface of adjustment pin and (not necessarily compress the flange of pin, flange is only a kind of embodiment herein, can be any structure of compression pin), it is identical that the moving direction of adjustment pin and the coating surface of adjustment pin point to the direction compressing the coating surface sold, also namely when adjustment pin moves relative to driven pulley by the effect of rope active force, squeezing action is produced to compression pin flanged structure.Below two replacement schemes are enumerated again:
As, adjustment pin 15 coordinates with driven pulley 10 right-handed thread, the winding direction of rope 12 in adjustment pin 15 is clockwise, adjustment pin 15 has the trend rotated counterclockwise, adjustment pin 15 has the trend along negative direction movement, compress the end face A that the flange 17a of pin 17 is pressed on adjustment pin 15, therefore adjustment pin 15 is difficult to negative direction and moves, and is also difficult to be rotated counterclockwise.
For another example, adjustment pin 15 coordinates with driven pulley 10 right-handed thread, the winding direction of rope 12 in adjustment pin 15 is counterclockwise, adjustment pin 15 has the trend rotated clockwise, adjustment pin 15 has the trend along positive direction movement, compress the flange 17a of pin 17 and can be designed to the end face B being pressed on adjustment pin 15, therefore adjustment pin 15 is difficult to positive direction and moves, and is also difficult to turn clockwise.
In such scheme, compress pin 17 can adopt be spirally connected, bonding, riveted joint, the mode such as welding and driven pulley 10 fixing.Preferably, compress between pin 17 and driven pulley 10 and adopt threaded engagement.Be specifically described as follows.
Adjustment pin 15 is identical with compression pin 17 rotation direction, and the flange 17a compressing pin 17 is pressed in adjustment pin 15.Under the effect of frictional force, when adjustment pin 15 has rotation trend, compressing pin 17 has the trend rotated with adjustment pin 15 rightabout, and the direction of the two mobile trend is also contrary.When the two have in opposite directions mobile trend time, thrust therebetween becomes large, and relative movement both stoping.
Adjustment pin 15 and driven pulley 10 left hand thread engagement, rope 12 wrapped anti-clockwise is in adjustment pin 15.The helicitic texture 17b compressing pin 17 is left hand thread, and the flange 17a compressing pin 17 after coordinating with the screwed hole 10h of driven pulley 10 is pressed on the end face A of adjustment pin 15.As shown in Figure 7, adjustment pin 15 has and to rotate clockwise and to the trend of negative direction movement, the flange 17a compressing pin 17 is pressed on the end face A of adjustment pin 15 under the effect of rope 12 active force, and under the effect of frictional force, compress pin 17 has the trend rotated counterclockwise.Owing to compressing pin 17 and driven pulley 10 left hand thread engagement, therefore the helicitic texture of pin 17 is compressed by precession certain length, namely the distance compressed between the flange 17a of pin 17 and driven pulley 10 will reduce, this can increase the pressure between flange 17a and adjustment pin 15 compressing pin 17, stop adjustment pin 15 to rotate clockwise, keep cord tightness degree.
For another example, adjustment pin 15 coordinates with driven pulley 10 right-handed thread, and rope 12 wound clockwise is in adjustment pin 15, and adjustment pin 15 has the trend rotated counterclockwise, and adjustment pin 15 has the trend along negative direction movement; Compressing pin 17 adopts right-handed thread to coordinate with between driven pulley 10, compress the end face A that pin 17 is pressed on adjustment pin 15, under frictional force effect, compress pin 17 have and to rotate clockwise and to the trend of positive direction movement, make adjustment pin 15 and the pressure increase that compresses between pin 17 and keep cord tightness degree.
For another example, adjustment pin 15 coordinates with driven pulley 10 right-handed thread, and rope 12 wrapped anti-clockwise is in adjustment pin 15, and adjustment pin 15 has the trend rotated clockwise, and adjustment pin 15 has the trend along positive direction movement; Compressing pin 17 adopts right-handed thread to coordinate with between driven pulley 10, compress pin 17 and can be designed to the end face B being pressed on adjustment pin 15, under frictional force effect, compress pin 17 have and to rotate counterclockwise and to the trend of negative direction movement, make adjustment pin 15 and the pressure increase that compresses between pin 17 and keep cord tightness degree.
When compressing pin 17 and being threaded engagement with driven pulley 10, compress the helicitic texture rotation direction of pin, the helicitic texture rotation direction of adjustment pin, compress pin and the adjustment pin endface position of flange pressing and rope in adjustment pin around to being the factor be associated, in order to ensure that compressing pin can prevent adjustment pin from rotating, can be coordinated by organic association of these factors and realize, it will be intended to: adjustment pin and compress that to sell rotation direction identical, compress pin to fit at axial direction with adjustment pin, under rope active force, it is identical that the moving direction of adjustment pin and the coating surface of adjustment pin point to the direction compressing the coating surface sold.When adjustment pin has mobile trend to produce squeezing action to compression pin by the effect of rope active force, compress and sell the rotating tendency that oriented driven pulley is close on the contrary, thus make the pressure between compression pin and adjustment pin larger, prevent adjustment pin from rotating.
