(54) ДИСКОВАЯ ПИЛА(54) DISK SAW

1one

Изобретение относитс  к устройствам дл  распиловки и может быть использовано в деревообрабатывающей промышленности .The invention relates to sawing devices and can be used in the woodworking industry.

Известна кругла  пила, включающа  диск, выполненный с прорез ми 1.A circular saw is known, including a disk made with slots 1.

Изготовление такой пилы затруднительно .Making such a saw is difficult.

Наиболее близким техническим решением к изобретению  вл етс  дискова  пила , включающа  диск с зубчатым венцом, центровым отверстием и прорез ми 2.The closest technical solution to the invention is a disc saw comprising a disk with a ring gear, a center bore and slots 2.

Недостатком этой пилы  вл етс  то, что она не обеспечивает устойчивости в процессе работы и снижение шума.The disadvantage of this saw is that it does not provide stability in the process of work and noise reduction.

Цель изобретени  - снижение шума и повышение устойчивости пилы в процессе работы.The purpose of the invention is to reduce noise and increase the stability of the saw during operation.

Цель достигаетс  тем, что прорези выполнены в виде отрезков логарифмической спирали, описываемой уравнением в пол рных координатахThe goal is achieved by the fact that the slits are made in the form of segments of a logarithmic spiral, described by the equation in polar coordinates

где / - пол рный радиус точки на логарифмической кривой;where / is the polar radius of a point on a logarithmic curve;

ср - угол пол рной координаты; ot - угол между вектором силы резани  и радиусом точки приложени  силы.cf is the angle of the polar coordinate; ot is the angle between the vector of the cutting force and the radius of the point of application of force.

причем отрезки спирали расположены с перекрытием друг друга в направлении радиуса диска.moreover, the segments of the spiral are overlapping each other in the direction of the radius of the disk.

На чертеже показана дискова  пила. Пила имеет зубчатый венец 1, центровое отверстие 2 и прорези 3, выполненные 10 в виде отрезков логарифмической спирали, описываемой уравнением в пол рных координатах .The drawing shows a circular saw. The saw has a ring gear 1, a center hole 2 and slots 3, made 10 in the form of logarithmic spiral segments, described by an equation in polar coordinates.

Наличие в пиле прорезей указанной формы позвол ет снизить шум за счет значительного сокращени  площади излучени , обеспечив при этом прочность диска пилы.The presence of cuts of this form in the saw allows reducing noise due to a significant reduction in the radiation area, while ensuring the strength of the saw blade.
