Изобретение относитс к чертежным гфиборам.FIELD: drawing drawing boards.
Известен чертежный прибор дл провецени окружностей больших циаметров, содержащий основание с пишущим устройством и ролики на полуос х С 11 .A known drawing device for proving circles of large diameters, containing a base with a writing device and rollers on semi-axes C 11.
Однако известный прибор имеет сложную конструкцию и неудобен в пользовании .However, the known device has a complex structure and inconvenient to use.
Цель изобретени - повышение удобства в пользовании.The purpose of the invention is to improve ease of use.
Поставленна цель достигаетс тем, что прибор имеет фрикционный фиксатор взаимного положени полуосей, одна из которых выполнена полой с продольным вырезом, а друга - установлена в полости первой, при этом фиксатор установлен в вырезе полуоси и соединен со второй полуосью.The goal is achieved by the fact that the device has a frictional lock for the relative position of the semi-axes, one of which is made hollow with a longitudinal notch, and the other is mounted in the first cavity, while the fixture is installed in the notch of the semi-axle and connected to the second semi-axle.
На чертеже изображен прибор дл проведени окружностей больших диамеггров .The drawing shows a device for conducting circles of large diameters.
Прибор содержит основание I с пишущим устройством 2 и съемные роликиThe device contains a base I with a writing device 2 and removable rollers
3 и 4 разного диаметра на полуос х 5 и 6, Полуось 5 выполнена полой с продольным вырезом 7, а полуось 8 установлена в полости полуоси 5. Фрикционный фиксатор 8 установлен в вырезе 7 полуоси 5 и соединен с полуосью 6.3 and 4 of different diameters on semi-axes x 5 and 6, Half-axle 5 is made hollow with a longitudinal notch 7, and semi-axis 8 is installed in the cavity of semi-axle 5. Friction latch 8 is installed in cut-out 7 of semi-axle 5 and connected to semi-axle 6.
Дл проведени окружности подбирают диаметры роликов и рассто ние между ними по формулеTo draw a circle, select the diameters of the rollers and the distance between them according to the formula
R-CR-c
аbut
где К - радиус описьтаемой окружности; С - рассто ние между роликами; сх - диаметр меньшего ролика; -fe - диаметр большего ролика.where K is the radius of the circumscribed circle; C is the distance between the rollers; cx is the diameter of the smaller roller; -fe is the diameter of the larger roller.
