Abstract
Изобретение относится к ролико-винтовому редуктору, содержащему передаточный механизм, который содержит винт, имеющий по меньшей мере одну пару резьбовых участков с резьбой различного направления, и ролики, расположенные вокруг винта и имеющие по меньшей мере две пары резьбовых участков с резьбой различного направления. При этом по меньшей мере два резьбовых участка роликов взаимодействуют с соответствующими резьбовыми участками винта, каждый из роликов содержит опорный поясок, расположенный между внутренними резьбовыми участками, а винт содержит опорный поясок, соответствующий опорным пояскам роликов, когда резьбовые участки винта взаимодействуют с крайними резьбовыми участками роликов, или каждый из роликов содержит два опорных пояска, расположенных по наружным сторонам крайних резьбовых участков ролика, а винт содержит два опорных пояска, соответствующих опорным пояскам роликов, когда резьбовые участки винта взаимодействуют с центральными резьбовыми участками роликов. При этом диаметры опорных поясков равны средним диаметрам резьбы взаимодействующих резьбовых участков роликов и винта соответственно. Технический результат заключается в исключении прогибания роликов и винта в передаточном механизме, исключении проскальзывания и повышении КПД редуктора.The invention relates to a roller-screw gearbox containing a transmission mechanism that contains a screw having at least one pair of threaded sections with threads in different directions, and rollers located around the screw and having at least two pairs of threaded sections with threads in different directions. At the same time, at least two threaded sections of the rollers interact with the corresponding threaded sections of the screw, each of the rollers contains a support belt located between the internal threaded sections, and the screw contains a support belt corresponding to the support belts of the rollers when the screw sections of the screw interact with the extreme threaded sections of the rollers , or each of the rollers contains two bearing bands located on the outer sides of the extreme threaded sections of the roller, and the screw contains two bearing bands, corresponding to rollers, when the threaded sections of the screw interact with the central threaded sections of the rollers. The diameters of the support bands are equal to the average thread diameters of the interacting thread sections of the rollers and the screw, respectively. The technical result consists in the elimination of the bending of the rollers and the screw in the transmission mechanism, the exclusion of slippage and the increase of the efficiency of the gearbox.
