(54) УЗЕЛ РЕЗАНИЯ КРУГЛОПИЛЬНОГО СТАНКА(54) KNOTTING CUTTING MACHINE

1one

Изобретение относитс к лесопильной и деревообрабатывающей промышленности , преимущественно к конструкци м круглопильных станков.The invention relates to the sawmill and woodworking industry, primarily to circular sawing machine designs.

Известен узел резани круглопильного станка, содержащий кольцевую пилу, установленную на внутренних поддерживаю- щих роликах, ведущие фрикционные диски, электродвигатель и боковые прижимные ролики 1.A known cutting unit of a circular saw, comprising a hole saw mounted on the inner supporting rollers, driving friction discs, an electric motor and side pressure rollers 1.

Недостатками такого устройства вл ютс ограниченное число оборотов коль- „ цевой пилы, так как ведущие диски небольшога диаметра привод тс во вращение от электродвигател через гибкий вал, что влечет за собой ограничение мощности передаваемой кольцевой пиле, сложность осуществлени надежного базировани кольцевой пилы на поддерживающих роликах.The drawbacks of such a device are the limited number of revolutions of the ring saw, since small diameter drive disks are driven by an electric motor through a flexible shaft, which entails limiting the power of the transmitted hole saw, the difficulty of making a reliable hole saw on the support rollers.

Известен также узел резани круглопильного станка, содержащий кольцевую пилу , установленную на центральном направл ющем диске, и имеющий по крайней мере две пары установленных по обе стороны 20 от кольцевой пилы прижимных роликов, оси вращени которых в каждой паре расположены в одной плоскости с осью вращени A cutting unit of a circular saw machine is also known, which includes a hole saw mounted on a central guide disk and having at least two pairs of pressure rollers installed on both sides 20 of the hole saw, each axis of rotation located in one pair with the axis of rotation.

кольцевой пилы, а прижимной ролик одной пары кинематически св зан с двигателем 2.the hole saw, and the pressure roller of one pair is kinematically connected with the motor 2.

Недостатками известногр узла резани вл ютс ризка надежность, ограниченное число оборотов кольцевой пилы, мала , передаваема на пилу, мощность и сложность конструкции. Это объ сн етс тем, что привод пилы осуществл етс только одним роликом , св занным с валом электродвигател через гибкий вал.The disadvantages of a well-known cutting unit are the risky reliability, the limited number of revolutions of the hole saw, which is small, transferred to the saw, and the power and complexity of the design. This is due to the fact that the saw is driven by only one roller connected to the motor shaft via a flexible shaft.

Цель изобретени - повыщение надежности привода и упрощение конструкции.The purpose of the invention is to increase the reliability of the drive and simplify the design.

Эта цель достигаетс тем, что прижимной ролик другой пары также кинематически св зан с двигателем, причем кинематическа св зь выполнена в виде фрикционного диска, который расположен соосно кольцевой пиле.This goal is achieved in that the pressure roller of the other pair is also kinematically connected to the engine, the kinematic connection being made in the form of a friction disk, which is located coaxially with a circular saw.

Claims

The cutting unit of the circular saw contains an electric motor 1 mounted on a bed 2; mounted on the shaft of the electric motor 1 a friction disk 3, a ring saw 4, freely rotating on the central guide disk 5, which is fastened with screws 6 to the base segments 7, which, in turn, are attached to the frame 2 by means of spikes 8; drive clamping friction rollers 9, the axis 10 of which is attached to the base segments 7 screws 11; clamping rollers 12, the axis 13 of which is fixed on the removable segments 14 by means of springs 15 and screws 16; guides 17 made of antifriction material, which are attached to the base segments 7 and removable segments 14 with screws 18. The cutting unit works as follows. From the electric motor 1, through the disk 3, the rotation is transmitted to the clamping friction rollers 9, which, together with the pressing rollers 12, drive the ring saw. Claims The cutting unit of a circular saw, comprising a hole saw mounted on a central guide disk and having at least two pairs of pressure rollers mounted on both sides of the hole saw, each axis of rotation located in the same plane with the hole saw axis, and the pressure roller of one pair is kinematically associated with an engine, characterized in that, in order to increase the reliability of the drive and simplify the design, the pressure roller of the other pair is also kinematically associated with motion Attic, wherein the kinematic coupling is designed as a friction disc which is disposed coaxially with the annular saw.
