Description
SPECIFICATION
Lubrication system for a drill rod shank in a percussion drilling machine
The present invention relates to a lubrication system for a drill rod shank in a percussion drilling machine, said drilling machine comprising
- a frame,
- a rotating sleeve rotatably mounted in the frame and having a housing for the shank of the drill rod,
- a tooth ring provided in the sleeve in axially slideable and rotating engagement with a tooth ring in the drill rod shank,
- a lubrication system for lubricating the tooth rings,
- rotating means for rotating the sleeve around the axis of the tooth ring, and
- percussion means for applying axial percussions on the drill rod shank.
Percussion drilling includes as an essential part rotation of the drill rod while the dril rod is simultaneously subjected to successive percussions. The rotating torque is transmitted from the rotating sleeve to the drill rod shank extending into the front end of the drilling machine by means of a groove coupling permitting an axial movement of the shank.
The groove coupling consists of a tooth ring formed by longitudinal grooves made in the inner surface of the sleeve and a tooth ring formed by longitudinal grooves made in the outer surface of the shank, said tooth rings being in engagement with each other.
The lubrication of the groove coupling is nowadays taken care of by means of oil mist (a mixture of air and oil) which is introduced in the coupling space at an air pressure of about 1 to 5 bar. Lubrication systems have also been used in which the coupling space is filled with low pressure oil, as described in
Finnish Patent Specification 58816.
In oil mist lubrication, however, the oil quantity entrained with the air will be too small in order to produce a sufficient lubrication. In oil mist and oil bath lubrication no oil will penetrate in between the operating flanks of the teeth in the tooth rings due to the low pressure and the location of the oil. The oil pressure does not open the operating flanks of the teeth which are pressed against each other because the pressure is equally high everywhere in the groove coupling. As a result, the teeth are rapidly worn.
The object of the present invention is to provide a lubrication system which eliminates the abovementioned disadvantages and permits an efficient lubrication of the operating flanks of the teeth in the tooth rings. This object is achieved by means of the lubrication asystem according to the invention which is characterized in that the lubrication system conducts lubricant under pressure between those flanks of the teeth in the tooth rings which are in pairs pressed against each other when the drill rod shank is rotated by the rotating sleeve.
The invention is based on the idea of conducting the lubricant directly to those tooth flanks which transmit torque and slide axially with respect to each other at such a pressure that the lubricant is able to penetrate in between the flanks. When the pressure of the lubricant produces in the flanks of the teeth a force greater than the tooth force, the flanks are opened so that a lubricating film is formed between the flanks. The released lubricant is removed from the groove coupling by means of compressed air or the lubricant flows away by means of its own pressure. lnthiswaylubricantwill befed in between the tooth flanks also when the flanks are transmitting torque, i.e. when a rock is drilled. Therefore, less friction heat is produced, the flanks do not sieze and the wear is reduced.
The invention will be described in more detail in the following with reference to the accompanying drawings, in which
Figure 1 is a schematical axial section of a percussion drilling machine which is provided with a lubrication system according to one embodiment of the invention and in which the rotation of the drill rod takes place continuously in the same direction,
Figure2 is a cross-section along line ll-ll in Figure 1,
Figure 3 is an enlarged axial section of the drill rod shank along line Ill-Ill in Figure 2,
Figure 4 is an axial section of a percussion drilling machine provided with a lubricant system according to a second embodiment of the invention,
Figure 5 is an axial section of a percussion drilling machine which is provided with a lubrication system according to a third embodiment of the invention and in which the rotation of the drill rod takes place alternatingly in different directions,
Figure 6 is an enlarged cross-section along line
VI-VI in Figure 5,
Figure 7 is an enlarged view of an alternative construction of one detail, and
Figure 8 illustrates a second alternative construction of the same detail.
The percussion drilling machine shown in Figures 1 to 3 of the drawings comprises a frame 1a, 1 bin which is rotatably mounted a rotating sleeve 2 provided on its outer surface with a toothing 3 which engages rotating means 4 mounted in the frame.
The sleeve comprises a cylindrical housing 5 receiving the rod-like shank 7 of a drill rod 6a, 6b. The shank is able to slide axially in the housing but is prevented from rotating with respect to the sleeve by means of a mutual groove coupling, which will be explained in more detail later.
The drilling machine further comprises a percussion piston 9 which is mounted axially slideably in the frame and is coaxial with the shank 7 so that the percussion piston is able to strike the end of the shank.
The groove coupling 8 comprises a tooth ring 10 on the inner surface of the sleeve and a tooth ring 11 on the outer surface of the shank in engagement with the first-mentioned tooth ring. As the sleeve is rotated by the rotating means in the direction of the arrow A, Figure 2, each tooth 12 of the tooth ring of the sleeve is with its flank 1 2a pressed against the flank 13a of each tooth 13 of the tooth ring of the shank.
According to the invention a bore 14 is made at each tooth of the rotating sleeve, said bore extend ing from the outer surface of the sleeve through the sleeeve to the flank 1 2a of each tooth. At the position of the bores 14 there is made in the machine frame 1 a peripheral groove which extends around the sleeve and forms a connection channel 15forall bores. The frame is provided with a bore 16 which connects the connecting groove to an connector 17 which is connected by a hose 18 to a pump 19 sucking lubricating oil from a container 20. In the frame is made a second bore 21 which connects a front chamber 22 provided in the frame for the shank to a connector 23 which is fastened to the frame and connected by a hose 24 through an oil filter 25 to the oil container 20.In order to prevent oil from flowing directly between the frame 1 and the sleeve 2, sealings 26 and 27 are mounted in the frame on both sides of the connecting channel 15. In order to prevent oil from flowing into the space of the percussion piston 9 and out of the machine between the drill rod and the frame, sealings 28 and 29 are mounted in the sleeve and the frame, respectively.
When drilling is carried out by means of the drilling machine, the pump 19 pumps oil through the hose 19 into the bore 16 and further through the connecting channel 15intothe bores l4ofthe sleeve. From these bores oil flows into a longitudinal groove 30 made in the flank 13a of each tooth 13 of the tooth ring of the shank, Figure 3. From the groove the oil flows out between the flanks 12a and 13aoftheteeth 12 and 13 when the oil pressure increases to a higher level than the force producing a rotary moment and pressing the flanks together.The oil flows through the gaps between the teeth of the shank and the teeth of the sleeve into the front chamber 22 from which it due to the oil pressure flowsthroughthe bore 21 and the hose 24tothe filter 25 and further to the oil container 20.
In the percussion drilling machine shown in Figure 4the lubrication system differs from the preceding one only in that the oil is discharged from the machine by means of compressed air. In the frame 1 is made a bore 31 which connects a connector 32 fastened to the frame to a groove 33 made in the percussion space of the percussion piston 9. The connector is connected by a hose 34 to a source of compressed air (not shown). No sealing is in this case provided between the sleeve and the drill shank. The hose 24 communicating with the front chamber 22 is through an oil cooler 35 connected to the filter 25 and further to an air/oil separator 36.
Compressed air entering through the bore 31 flows through the gaps between the sleeve and the shank into the front chamber 22 and removes the excessive oil with it.
An oil container may be provided between the separator 36 and the pump 19 for storing a larger oil quantity.
If compressed air is used for removing, for example, drill cuttings from the drill hole, which air is fed into the drill hole along a channel in the drill rod, the compressed air required for oil removal can be taken through a bore from a feed channel system connected to said channel, in which case no separate feeding 31-34 of compressed air is required for the removal of oil.
The percussion drilling machine shown in Figures 5 and 6 is of a type in which the direction of rotation of the rotating sleeve is continuously changed during drilling. In this case both flanks 12a and 12b and 13a and 13b, respectively, of each tooth of the tooth rings 10 and 11 forming the groove coupling,
Figure 6, will act as torque transmitting flanks which requires lubrication. In order to provide the lubrication, the oil feeding channel system 14-17 for lubricating the flanks 1 2a of the teeth of the sleeve are complemented by a similar separate oil feeding channel system 14-17 for the other flanks 1 2b of the teeth of the sleeve.The oil feeding channel systems are located at a distance from each other in the axial direction of the shank and are isoiated from each other by means of a sealing 26 mounted in the frame. A connector 17' is connected to the pump 19 through a three-way valve 37 which is mounted in the hose 18 and which receives its control 38 from the rotating means 4 so that when the rotating means are rotating in different directions A and B the valve 37 in sequence closes the connection from the pump to one connector and opens the connection from the pump to the connector of that feed channel system which in each particular case is leading to the torque transmitting flanks 1 2a and 12b. In this cse a longitudinal groove 30', Figure 6, is made also in the other flank 13b of the teeth 13 of the shank.
Figures 7 and 8 show two alternative manners of forming the connecting channel 15. In Figure 7 the connecting channel 15" comprises only a ring groove made in the sleeve 2. In Figure 8 ring grooves, which together form a connecting channel 15"', are made both in the frame 16 and in the sleeve 2. In both cases sealings are mounted in the frame 1 b because the frame due to its thickness usually has more space for sealings than the sleeve. Alternatively, the sealing may of course be mounted also in the sleeve.
The drawings and the description related thereto are only intended to illustrate the idea of the invention. In its details the lubrication system according to the invention may vary within the scope
