Задача №21.12
Условие
В некоторых измерительных и делительных приборах для перемещения указателя применяется дифференциальный винт, состоящий из оси AB, имеющей в части A винтовую нарезку с шагом h1 мм, а в части B — нарезку с шагом h2<h1. Часть A вращается в неподвижной гайке C, а часть B охватывается элементом D, лишенным вращательного движения и соединенным с указателем, скользящим вдоль неподвижной шкалы. 1) Определить перемещение указателя при повороте маховичка оси на 1/n оборота (соответствующая шкала нанесена на диске E), если n=200, h1=0,5 мм и h2=0,4 мм. Обе нарезки правые или обе левые. 2) Как изменится показание прибора, если в части A сделать левую нарезку, а в части B — правую?Решение
