Description
Technical field
The present invention relates to a kind of dynamic gas transmission device, especially relate to a kind of high precision dynamic gas transmission device for corrugated machine.
Background technology
At present, the transmission system of making the corrugated machine of packaging material corrugating media mainly is to adopt through-drive, mainly contains two kinds on rolling bearing and sliding bearing and be used for driven off by shaft bearing.But these two kinds of bearings have direct contact of bearing and axle, and such bearing can produce very big friction in machine operation, cause the lot of energy loss; Simultaneously, friction can be shortened the service life of machinery again; Moreover the friction on the bearing also can produce very big noise, and is healthy harmful to the technical staff who uses this machinery.
Chinese patent CN No. 86104100 disclosed gas bearing, though avoided direct contact of bearing and axle, can reduce friction loss significantly, still, this bearing can not bearing axial pushing force, and complex structure, inconvenient operation, practicality is lower.
Summary of the invention
The object of the present invention is to provide a kind of energy consumption low, friction noise is low, and the positioning accuracy height is simple in structure, but bearing axial pushing force is applicable to the high precision dynamic gas transmission device that corrugated machine is used.
Technical scheme of the present invention is: it comprises axle, axle sleeve, on axle sleeve, be provided with uniform passage, described passage has three rows at least, the axis normal of wherein at least one row and axle, angle is 40 °-80 ° between the radial direction of other inclined hole and axle, on every row's passage gas flow control valve is installed all, at the shaft shoulder place of axle seal is installed, the space between axle and the axle sleeve has been full of the gases at high pressure that perfusion is come in from passage; The end that axle is enclosed in the axle sleeve is provided with cannelure, at least three displacement transducers are installed on the axle sleeve, described displacement transducer is electrically connected with the PLC central processing unit by data collecting system respectively, the PLC central processing unit is connected with gas flow control valve on being installed in passage, according to the displacement signal that receives, the PLC central processing unit can be controlled the running of gas flow control valve.
Described displacement transducer is divided into radial displacement transducer and shaft position sensor, and two radial displacement transducers along continuous straight runs and vertical direction respectively are arranged on the axle sleeve, and shaft position sensor is located at sleeve end.
Described passage should be divided into three rows along circumferentially being uniformly distributed on the axle sleeve, the axis normal of a row and axle wherein, and two row's passages are inclined hole in addition, and angle is 60 ° between the radial direction of axle.
The inwall of described axle sleeve is provided with the arc bulge loop with the corresponding position of cannelure of axle.
Described seal can be selected rubber seal for use.
Described gaseous species is not limit, and can be gas, can be inert gas (for example nitrogen) etc. yet.
The present invention is simple in structure, can reduce friction, and saves the energy more than 20%, effectively reduce the noise that produces in the running, prolonged mechanical service life, running speed can improve more than 40%, positioning accuracy height, but bearing axial pushing force are applicable to that corrugated machine uses.
Description of drawings
Fig. 1 is the structural representation (front view) of one embodiment of the invention.
Fig. 2 is the left view of axle sleeve embodiment illustrated in fig. 1.
The specific embodiment
The invention will be further described below in conjunction with accompanying drawing.
With reference to accompanying drawing: present embodiment comprises axle 1, axle sleeve 2, on axle sleeve 2, be provided with uniform passage 6, described passage 6 is divided into three rows, wherein one row with the axle axis normal, angle between the radial direction of other two row's inclined hole and axle is 60 °, be separately installed with corresponding gas flow control valve 7,8,9 on three row's passages, at the shaft shoulder 4 places of axle 1 rubber seal 3 be installed, the space between axle 1 and the axle sleeve 2 has been full of the gases at high pressure 11 that perfusion is come in from passage 6; The end that axle 1 is enclosed in the axle sleeve 2 is provided with cannelure 5, axle sleeve 2 ends are equipped with shaft position sensor 12, the vertical direction of axle sleeve 2 is equipped with radial displacement transducer 10, horizontal direction is equipped with radial displacement transducer 15, shaft position sensor 12 is connected with PLC central processing unit 14 by data collecting card 13 respectively with vertical direction radial displacement transducer 10 and horizontal direction radial displacement transducer 15, PLC central processing unit 14 and the gas flow control valve 7 that is installed in respectively on three row's passages 6,8 are connected with 9, according to the displacement signal that receives, the PLC central processing unit can be controlled gas flow control valve 7,8,9 running.
In described three row's passages 6, with centre one row's passage of the axis normal of axle 1, mainly be responsible for offering the air-flow that axle 1 applies radial load and keeps radial clearance, other two row's inclined holes mainly are responsible for providing the axial displacement of regulating shaft 1 and the air-flow of pressure.
The inwall of described axle sleeve 2 is provided with the arc bulge loop with the cannelure 5 corresponding positions of axle.
Rubber seal 3 main sealing and the dustproof effect of rising.
When equipment runs well, shaft position sensor 12 and vertical direction radial displacement transducer 10 and horizontal direction radial displacement transducer 15 are ceaselessly measured axle 1 gap in each position, send the correlation displacement data to PLC central processing unit 14 by data collecting card 13 then, central processing unit 14 compares displacement data and the setting value that collects, when certain data changes, central processing unit 14 will send instruction, regulate corresponding flow control valve 7,8 or 9, thereby control the gas flow of corresponding passage, reach the purpose of regulating shaft 1 position at last.Such as: the gap data of passing back when vertical direction radial displacement transducer 10 is bigger than setting value, just explanation is axially mobile down for this, after PLC central processing unit 14 obtains this information, just assign instruction immediately, regulate vertical direction gas flow control valve 8, the flow in up-draught hole is strengthened, and down-draught hole gas flow reduces, thereby axle 1 is come back on the correct position.
