Abstract
The worm screw group cosists of a set of motive worm screw and a sset of displacement controlling worm screw both of which are coupled with the same worm gear. When the system is driven, one set of worm serew is applied the turning driving more quickly and applies force constantly to the worm wheel group, the other set of worm screw is a displacement controlling worm screw and also coupled to the same worm wheel group (or ganging locked separate worm wheel group with same pitch or different pitch). Owing to the acting force applied constantly to the worm gear by force applying worm screw makes the displacement controlling worm screw be reverse pressed tightly on the worm gear and because the drive of worm screw group is non reversable, so there is no gap between the worm gear and two sets of worm screws.
Description
The present invention relates to a kind of double-acting dynamic back clearance-eliminating driving system, mainly have as former moving worm screw and displacement amount and control two groups of the worm screw worm screws groups with the worm gear coupling, when system is driven, wherein one group of former moving worm screw is applied faster that revolution drives and perseverance forces in worm gear, other one group of worm screw is that displacement amount is controlled worm screw, also be coupled in this worm gear (or indivedual worm gear of the same pitch of coaxial locking or different pitches), because application of force worm screw perseverance imposes on the active force of worm gear, make this displacement amount control the worm screw perseverance by the reverse worm gear that is packed in, because the worm screw group is irreversible transmission, therefore be gapless state between worm gear and two worm screws, this moment is when our drive displacement amount is controlled the past pressurized direction of worm screw and retreated, worm gear because of the driving that is subjected to the former moving worm screw of the application of force do to chase be moved to once again the packing displacement amount and control worm screw till, and form according to the load back clearance state poor dynamic back clearance-eliminating driving system of regulating the speed voluntarily, relative, also can change into the driving that makes above-mentioned former moving worm screw on arranging to the application of force drive mechanism of two worm screws group is rigidity, slidably coupled drive and displacement amount are controlled worm screw and jointly the load worm gear are done the zero-clearance clockwise and anticlockwise and drive and the driving that displacement amount is controlled worm screw is for the limit torsion of very fast rotating speed, still by means of above-mentioned principle, can reach dynamic back clearance eliminator in the motion; Above-mentioned irreversible transmission component also can be made of the screw rod nut block, to drive worktable or mechanical structure.
Promptly the system according to above-mentioned announcement comprises:
Irreversible to transmission by kinetoplast A, and two groups with the kinetochore of its coupling as power resources, wherein one group is force application driving body B, another is organized to displacement amount and controls kinetochore C; It is characterized by force application driving body B, or displacement amount is controlled kinetochore C to done irreversible application of force transmission by kinetoplast A; Aforementionedly be can be worm gear by kinetoplast A, force application driving body B and displacement amount are controlled kinetochore C and be can be the worm screw group; Or by kinetoplast A can be the tool drive nut by kinetoplast, force application driving body B and displacement amount are controlled kinetochore C and be can be screw rod group (kinetochore is with also same by the screw rod of kinetoplast and nut exchange setting), to constitute two-way transmission, according to the load back clearance state poor dynamic back clearance-eliminating driving system of regulating the speed voluntarily, its action principle is as follows:
