Description

ii

Изобретение относитс к горной промьш Ленности , в частности к бурильным машинам с независимым вращением буровогд ин струмента.The invention relates to the mining industry of Lozenia, in particular, to drilling machines with independent rotation of the drill-driver tool.

Известен перфоратор с независимым вращением инструмента, вращатель которого содержит рабочую пару с зубь ми кругового профил и разностью в числах зубьев, равной единице, причем большое зубчатое колесо неподвижно; а малое колесо, зацепл сь с большим, совершает планетарное движение и несет устройство распределени текучей среды 1 .A perforator with independent rotation of a tool is known, the rotator of which contains a working pair with teeth of a circular profile and a difference in the numbers of teeth equal to one, and the large gear wheel is stationary; and the small wheel, hooking up with the large one, performs a planetary motion and carries a fluid distribution device 1.

Недостатком такой конструкции вл етс сравнительно низкий КПД передачи вращени от ротора к шпниделю, что особенно сказываетс при переходе к более высокому давлению текучей среды и уменьшении в св зи с этим габаритов рабочей пары.The disadvantage of this design is the comparatively low efficiency of the transfer of rotation from the rotor to the spindle, which is especially evident when switching to a higher fluid pressure and reducing the size of the working pair in connection with this.

Наиболее близким решением по технической сущности и достигаемому- результату вл етс вращатель бурильной машины, включающий корпус, размещенные в нем большое и малое зубчатое колеса, наход щиес во внутреннем зацеплении и образующие т: корпусом рабочие камеры переменного объема 2.The closest solution to the technical essence and the achieved result is a rotator of a boring machine that includes a case, a large and a small gear housed therein, which are in internal gearing and which form a variable volume working chambers 2: the case.

Целью изобретени вл етс повышение мощности зращател .The aim of the invention is to increase the power of the spinner.

Дл достижени указанной цели радиальные каналы распределительного устройства выполнены из отдельных участков в неJ скольких герметично скрепленных дисках.To achieve this goal, the radial channels of the switchgear are made of separate sections in several hermetically sealed disks.

На фиг. 1 изображен предлагаемый врз щатель, разрез Б-Б фиг. 2; н фиг. 2 - разрез А-А фиг. 1; иа фиг, 3 - разрез В-В фиг. 1.FIG. 1 shows the proposed slitter, section BB of FIG. 2; n FIG. 2 - section A-A of FIG. one; fig 3, section bb of fig. one.

Вращатель содержит большое зубчатое О колесо 1 с вращающимис роликами - зубь ми 2 на внутренней поверхности и малое зубчатое колесо 3, аксиально оданжно посаженное на шпиндель 4.The rotator contains a large gear wheel 1 with rotating rollers - teeth 2 on the inner surface and a small gear wheel 3, axially mounted on the spindle 4.

К ротору с помощью штифтов 5 прикреплен распределительный диск, сост о щий из герметично скрепленных заклепками 6 дисков 7, 8, 9, 10 и 11. В диске 7 выполнены входные отверсти 12 (фиг. 1 и 3), а в диске 1 - выходные отверсти 13. Отверсти 12 и 13 сообхцены между собой 0 участками 14, 15 и 16 в диске 8, участками 17 и 18 в диске 9 и участками 19 и 20 каналов в диске 10.A distributor disk is attached to the rotor by means of pins 5, which consist of 6 disks 7, 8, 9, 10, and 11 hermetically sealed with rivets. In disk 7, the inlet holes 12 are made (Fig. 1 and 3), and in disk 1, the output openings 13. Openings 12 and 13 are shared between themselves 0 by sections 14, 15 and 16 in disk 8, sections 17 and 18 in disk 9, and sections 19 and 20 channels in disk 10.

Claims

The large wheel I is provided with outer teeth 21 meshed with the internal teeth 22 of the housing 2i3. The support surfaces of index 1 are placed in the cornea 23, which also includes receiving chambers with an inlet 24 and a tap 25 communicated with threaded holes 26 and 27, the annular groove 28 of the housing with holes 29 communicates with the receiving chamber of the transducer 24, and the annular groove 30 with holes 31 communicates with the retraction chamber 25. For fastening parts of the rotator and impact unit, fastening bolts 32 are used. The rotator works in the following manner. The fluid from the threaded bore 26 enters the supply chamber 24 and then through the openings 29 and the annular groove 28. Since the distribution disc associated with the large gear wheel 1 is eccentric with respect to the housing 23. Only half of the inlet grooves 28 are aligned with the annular groove 28. holes 12, and the fluid in sections 14, 15, 16, 17, 18, 19, 20 and 13 of the channel enters half of the working channel, measures 33 formed by the contacting teeth, boliyugo 1 and small 3 gears. By the pressure of the fluid, the large gear wheel 1 is driven into a planetary motion and, engaging simultaneously with the body 23 and the small gear wheel 3, causes the latter to rotate. In this case, the other half of the working chambers34 are similarly associated with ka, a measure of tap 25 to displace the spent fluid. Moving the switchgear out of the bounds of the big gear (; the forest can reduce its diameter and at the same time increase the diameter of the channel inlets and thereby increase the capacity of the switchgear, reduce the pressure loss in it and increase the power of the rotator, and also to simplify its manufacture, the claims of the invention of the rotator boring maschiny, including the body, large and large gears placed in it, which are located in the internal hook, are molded and form e with a housing, working chambers of variable volume, and a distribution device mounted on a large wheel with axial and radial fluid supply channels, differing in that, in order to increase the power of the rotator by increasing the cross section of the channels, the radial channels of the distribution device are made of separate sections in several hermetically sealed disks.
