The working principle and the beneficial effects of the technical scheme are as follows: in the first embodiment, the overload prevention planetary gear 5 adopts the structure that the embedded block 54 deforms to slide relative to the overload prevention planetary carrier 51, so that the overload prevention effect of the overload prevention planetary gear 5 is achieved, but the first embodiment has strong dependency on the nature of the embedded block 54, and firstly, the embedded block needs to be an elastic part, and the maximum torque of the overload prevention planetary gear 5 depends on the friction force between the fixture block and the clamping groove. Meanwhile, the invention provides a second embodiment, in this embodiment, the requirements on the material and the self property of the embedded block 54 are low, wherein the side wall of the accommodating groove, the side wall of the clamping groove, the side wall of the embedded block 54 and the side wall of the fixture block are arc-shaped surfaces, that is, the cross section is arc-shaped, when the overload prevention planet wheel 5 is started, the embedded block 54 and the arc-shaped surfaces of the fixture block can conveniently slide out from the accommodating groove, and the arc-shaped surfaces can reduce deformation when the embedded block 54 is embedded and slides out, so that the service life is prolonged.
When the overload prevention planetary gear 5 normally rotates, the fixing sleeve 75 is sleeved at the end of the overload prevention sun gear 53, and the reset piece 76 applies thrust to the sliding block 72, so that the sliding block 72 can abut against the limiting section 731 and abut against the fixing sleeve 75 through the connecting rod 74, so that pressure is provided for the overload prevention sun gear 53, and the overload prevention sun gear 53 can be connected with the overload prevention planetary carrier 51 to transmit torque. The pressure that the reset element 76 can provide to the overload prevention sun gear 53 is the maximum torque of the overload prevention planetary wheels 5.
When the overload prevention planetary gear 5 starts, the overload prevention planetary carrier 51 continuously rotates, the embedded block 54 is jacked up by the overload prevention planetary carrier 51 along the arc-shaped surface along with the rotation of the overload prevention planetary gear 5, so that the overload prevention sun gear 53 pushes the fixed sleeve 75, and the slide block 72 is pushed by the connecting rod 74 to extrude the reset piece 76, so that the transmission disconnection between the overload prevention planetary gear 5 and the input planetary gear 4 is realized.
When the overload prevention planetary gear 5 is reset, the reset piece 76 pushes the slide block 72 to reset, and the overload prevention sun gear 53 is reset. So that the transmission is continued.
Through the structural design, the sliding type in the first embodiment is converted to the pull-out type, so that the requirement on the material property of the embedded block 54 is reduced, the fatigue caused by repeated deformation of the embedded block 54 is reduced, the service life of the embedded block 54 is prolonged, the pull-out type overload prevention planetary gear 5 can be supported and reset through the reset movable member 7, the maximum torque of the overload prevention planetary gear 5 can be adjusted through the adjustment of the reset member 76, and the applicable torque range of the overload prevention planetary gear 5 is increased.
In the third embodiment, an auxiliary separating device 8 is disposed at the bottom of the insertion block 54, the auxiliary separating device 8 penetrates through the overload prevention planet carrier 51 and is movably connected with the end of the input sun gear 43, and the auxiliary separating device 8 includes a mounting cylinder 81, a fixing head 82, a spring 83, an upper chuck 84 and a lower chuck 85; lower dop 85 sets up input sun gear 43's tip, and with the one end butt of installation section of thick bamboo 81, go up dop 84 with spring 83 all sets up in the installation section of thick bamboo 81, lower dop 85's lateral wall with the arch 811 swing joint of installation section of thick bamboo 81 inner wall, go up dop 84's one end with dop 85 swing joint down, go up dop 84's the other end through spring 83 with fixed head 82 connects, fixed head 82 with embedded block 54 connects. Go up dop 84's tip with dop 85's tip all is the annular and is provided with the tooth that has the slope down, and the one end of tooth has the slope, the lateral wall of going up dop 84 is provided with recess 841, and the lateral wall of recess 841 is the inclined plane, just the protruding 811 width of installation section of thick bamboo 81 inner wall is less than the width of recess 841, the protruding 811 and the recess 841 swing joint of installation section of thick bamboo 81 inner wall.
The working principle and the beneficial effects of the technical scheme are as follows: in the second embodiment, although the arc-shaped face can facilitate the removal of the insertion block 54, if a rigid material is used, the removal of the insertion block 54 is relatively difficult, so the invention provides a third embodiment, on the basis of the second embodiment, an auxiliary separating device 8 is additionally arranged at the bottom of the insertion block 54 to assist the removal of the insertion block 54 from the accommodating groove, and a sound can be given to remind an operator when the overload prevention planetary gear 5 is activated.
When the overload prevention planetary gear 5 is not used, the upper chuck 84 and the lower chuck 85 are in a meshed state, teeth on the upper chuck 84 and the lower chuck 85 are arranged in an annular shape, each tooth has a slope, the side face of each tooth is perpendicular to the end faces of the upper chuck 84 and the lower chuck 85, so that the upper chuck 84 can be clamped with the lower chuck 5, the slope face of the tooth of the upper chuck 84 is abutted to the slope face of the tooth of the lower chuck 85, and the end face of the tooth of the upper chuck 84 is abutted to the end face of the tooth of the lower chuck 85.
When the overload prevention planetary gear 5 is started, when the embedded block 54 is not completely disengaged from the overload prevention planetary carrier 51, the embedded block 54 rotates relative to the accommodating groove by a certain angle due to the influence of the arc-shaped surface as the embedded block 54 is separated from the bottom surface of the accommodating groove, when the embedded block 54 rotates angularly, the embedded block screws the spring 83 through the fixing head 82, so that the upper chuck 84 is driven to rotate with the lower chuck 85, as the spring 83 screws, the spring 83 is in a stressed state and compresses, and when the upper chuck 84 rotates relative to the lower chuck 85, the teeth of the upper and lower chucks slide relative to each other along the slope, because the lower chuck 85 is fixed to the input sun gear 43 through a screw, the upper chuck 84 moves upward along the slope of the teeth of the lower chuck 85 and further compresses the spring 83, so that the spring 83 provides a pushing force for disengaging the embedded block 54, to achieve an effect of assisting disengagement of the lower chuck, when the embedded block 54 is disengaged, the spring 83 releases the spring force, when the embedded block 54 is restored and the spring 83 is pushed again to move upward, so that the upper chuck 84 and the lower chuck moves to move relative to make the lower chuck work continuously and the lower chuck 85 and the lower chuck work like when the ball pen clicks act on the lower chuck 85, the ball pen, and the ball pen driver works.
When overload prevention planet wheel 5 returns to transmission, groove 841 on the side wall of upper chuck 84 can limit with protrusion 811, and because the width of protrusion 811 is smaller than the width of groove 841, when spring 83 is compressed torsionally, protrusion 811 and groove 841 can also collide to generate sound, and because the side wall of groove 811 is a slope, upper chuck 4 can rotate while moving upwards.
