3rd, application method and principle：
（One）, power transmission
When device works normally, in the case where cylindrical spring 22 acts on the pressure of clutch shaft 23, the anti-overload of driving on clutch shaft 23 Tooth 25 is tightly engaged with the passive anti-overload tooth 28 on main cone wheel shaft 27, and power passes through input shaft 20, clutch shaft 23 and main cone wheel Axis 27 is transmitted to active cone pulley 29, and driving active cone pulley 29 rotates, and active cone pulley 29 is transferred power to by live roller 55 Driven cone pulley 33, then power is exported by output shaft 32.
（Two）, arrangement of clutch
Due to being driven between active cone pulley 29, live roller 55 and driven cone pulley 33 by frictional force, on output shaft 32 Load increases, the torque increase on output shaft 32, driven cone pulley 33, active cone pulley 29 and main cone wheel shaft 27, driven 33 He of cone pulley Frictional force increase between live roller 55, live roller 55 and active cone pulley 29, to avoid driven cone pulley 33 and live roller Frictional force between 55 or live roller 55 and active cone pulley 29 is more than its maximum static friction force and slides, generates abrasion, It needs to set overload protection arrangement, rubbing between driven cone pulley 33 and live roller 55 or live roller 55 and active cone pulley 29 It wipes before power is more than its maximum static friction force and power is cut off, clutch shaft 23 realizes that the principle of overload protection is as follows：Clutch When the anti-overload tooth 25 of driving on axis 23 is intermeshed with the passive anti-overload tooth 28 on main cone wheel shaft 27, passive anti-overload tooth 28 To driving normal direction of the reaction force of anti-overload tooth 25 along contact surface, which will generate one along 23 axis of clutch shaft Component on direction and one are along the component in 23 tangential direction of clutch shaft, the influence of negligible friction, the axial thrust load with The pressure balance that cylindrical spring 22 generates clutch shaft 23, and drive tangential component pair of the anti-overload tooth 25 to driven tooth active force Main cone wheel shaft 27 generates torque, and driving main cone wheel shaft 27 is rotated synchronously with clutch shaft 23, when the load on input shaft 20 is more than volume During fixed load G1, the torque that anti-overload tooth 25 generates main cone wheel shaft 27 tangential component of driven tooth active force is driven to be not enough to Driving main cone wheel shaft 27 rotates, and anti-overload tooth 25 is driven to be slid along the contact surface direction with driven tooth, until and driven tooth It is disengaged from, the transmission of power is cut off, and nominal load G1, which is less than, makes driven cone pulley 33 and live roller 55 or live roller 55 The minimum load G2 of slip is generated between active cone pulley 29.
（Three）, variable speed
Since active cone pulley 29 and driven cone pulley 33 are truncated cone-shaped, and placement direction is led on the contrary, on different vertical sections Mantle wheel 29 and the diameter of driven cone pulley 33 change, and gearratio is live roller 55 and active cone pulley 29 or driven cone pulley 33 The diameter ratio of the diameter of driven cone pulley 33 and active cone pulley 29 on the vertical section of contact position, when rotating speed governing knob 64, speed governing Knob 64 passes sequentially through main regulation gear 61, speed adjustment screw 56 is driven to rotate from adjustment gear 60 and universal joint 57, due to sliding block Slide block guide rail 59 on nut 50 is slidably connected in slideway groove 41, and speed adjustment screw 56 will drive slider nut 50 recessed along slideway Slot 41 is moved forward and backward, and changes the relative position of live roller 55 and active cone pulley 29 and driven cone pulley 33, so as to fulfill transmission Than adjusting, the angle that speed governing knob 64 rotates, into correspondence, is carved with 55 position of live roller by the speed ratio on housing seat 10 The value that degree 68 can read gearratio, to be driven when live roller 55 is located at the centre position of active cone pulley 29 or driven cone pulley 33 The separation of ratio, the gearratio of active cone pulley 29 and driven cone pulley 33 is 1 at this time:1, sound producing ball 47 connects with sounding collision column cap 53 It touches, is rotated further speed governing knob 64, sound producing ball 47 will rebound and hit the inner wall of sounding wall 45, send out ring prompting.
