Изобретение относитс к конструкци м исполнительных органов камнерезных машин дл вырезани крупных блоков камн из горного массива.The invention relates to the design of the executive bodies of stone-cutting machines for cutting large blocks of stone from a rock mass.

Известна кольцева пила, включающа приводное кольцо с эвольвентными зубь ми нарезанными по его периферии, на вершинах которых закреплены резцы, причем приводное кольцо установлено на опорном кольце , которое в свою очередь крепитс к раме камнерезной машины 1.A known circular saw includes a drive ring with involute teeth cut along its periphery, on the tops of which cutters are fixed, the driving ring being mounted on a support ring, which in turn is attached to the frame of the stone-cutting machine 1.

Недостатком известного устройства вл етс ненадежность конструкции сальниковых уплотнений и всего механизма креплени приводного кольца.A disadvantage of the known device is the unreliability of the structure of the stuffing boxes and the whole mechanism for fastening the drive ring.

Наиболее близким к изобретению техническим решением вл етс кольцева пила дл резани горных пород, включающа корпус , выполненный в виде неподвижных щек с закрепленными на них опорными роликами и приводное кольцо с резцами, на боковых поверхност х которого выполнены кольцевые пазы, в которых размещены опорные ролики 2.The closest technical solution to the invention is an annular saw for cutting rocks, comprising a body made in the form of fixed cheeks with supporting rollers fixed on them and a drive ring with incisors, on the side surfaces of which annular grooves are made, in which the support rollers 2 are placed .

Недостатком известной конструкции кольцевой пилы вл етс недостаточна A disadvantage of the known ring saw design is insufficient

пылеизол ци вращающихс опор, что отрицательно вли ет на долговечность кольцевой пилы и, в конечном итоге, на надежность .dusting out rotating supports, which negatively affects the durability of the hole saw and, ultimately, reliability.

Целью изобретени вл етс повышениеThe aim of the invention is to increase

долговечности и надежности кольцевой пилы .durability and reliability of a ring saw.

Дл достижени поставленной цели в кольцевой пиле, дл резани горных пород, включающей корпус, выполненный в видеTo achieve this goal, in a hole saw, for cutting rocks, including a body made in the form of

неподвижных щек с закрепленными на них опорными роликами, и приводное кольцо с резцами, на боковых поверхност х которого выполнены ко тьцевые пазы, в которых размещены опорные ролики, корпус снабжен планками, в которых смонтированыfixed cheeks with supporting rollers fixed on them, and a driving ring with incisors, on the lateral surfaces of which the grooves are made, in which the supporting rollers are placed, the housing is equipped with slats in which are mounted

опорные ролики под углом 45° к плоскости приводного кольца, а кольцевые пазы выполнены треугольной формы с пр мым углом при вершине на разных радиусах.the support rollers are at an angle of 45 ° to the plane of the drive ring, and the annular grooves are triangular with a right angle at the apex at different radii.

На фиг. 1 изображен общий вид пилы.FIG. 1 shows a general view of the saw.

Claims

FIG. 2 - support roller construction. The ring saw consists of two supporting cheeks 1 in which windows 3 are cut at different radii equal to the radii of the grooves of the movable ring 2 Rollers 5 are located in the windows on the moving bars 4, which, alternately with the corresponding groove track 6, provide reliable fixing the movable ring 2 relative to the supporting cheeks I. The design of the roller, located on the radial bearing 7, mounted on the axis and insulated from the environment by means of the cover 8 and the stuffing box seals 9, allows tion work without additional pyleizol tion zone conjugated voltage rollers with cutter ring. The principle of matching each of the rollers with the corresponding groove track b significantly increases the rigidity of the structure, and the ability to move the strip 4 in the cheek 3, which cnoco6cTfiyioT bored mounting holes 10 of the strip 4, creates a prerequisite for adjusting the cutter as the rollers wear or bend Rf. groove. The work of the hole saw is as follows. The ring 2 is set in rotational motion by a gear wheel seated on the output shaft of the drive by means of an involute gearing. The ring, with incisors fixed on the tops of the involute teeth, rotates about its axis, fixed relative to the stationary supporting cheeks 1 by means of its grooves 6 liters of rollers 5 locked in the above-mentioned cheeks. When the feed movement is ensured, the cutting process of the rock mass occurs. Claim 1. Circular saw for cutting rocks, comprising a body made in the form of fixed cheeks with supporting rollers fixed on them and a drive ring with cutters, on the side surfaces of which circular grooves are made, in which support rollers are placed, characterized in that that, in order to increase durability and reliability, the housing is provided with strips in which the support rollers are mounted at an angle of 45 ° to the plane of the drive ring, and the annular grooves are made triangular with a right angle at the apex. 2. Ring saw, according to claim 1, characterized in that the annular grooves on both sides of the curtain ring are made on different radii.
