Description
Technical field
The present invention relates to plant equipment manufacturing technology field, especially a kind of dress that whole axial gap is raised for rotating shaft
Put.
Background technology
In assembling, the thickness for generally requiring to adjust bearing gasket between bearing face and bearing cap comes for the rotating shaft of plant equipment
Carry out the axially mounted gap of rotating shaft；A kind of rotating shaft 10 as shown in Figure 1, the rotating shaft 10 is by being installed on the bearing 20 at its two ends
On cylindrical slide 40, cylindrical slide 40 is connected by bolt with casing 50；Slided with cylindricality in the left side of the outer ring of bearing 20
Bearing gasket 30 is provided between the bearing gland end of block 40.During installation, first bearing gasket is installed by the thickness of calculated value,
The thick or thin phenomenon of bearing gasket now occurs, therefore, must be according to multiple component assemblies after, by survey rigging error adjust
The thickness of bearing gasket, is installed next time；But need the part of dismounting more in a pre-installation, it cannot be guaranteed that original after installation
Installation accuracy, therefore can just control rigging error in allowed band it cannot be guaranteed that installing again, it is sometimes desirable to dismount multiple ability
Complete adjustment；Being dismounted for multiple times can destroy bearing hole dimensional accuracy, so that installation accuracy is influenceed, low production efficiency.
The content of the invention
The technical problems to be solved by the invention are to provide one kind and conveniently and efficiently can carry out axial gap adjustment by countershaft
Axial interval regulator, with solve bearing gasket during existing installation rotating shaft thickness must repeated disassembled and assembled, adjustment just can determine that
Problem.
The technical proposal for solving the technical problem of the invention is：This axial interval regulator includes rotating shaft,
By bearing mounted in one end of cylindrical slide, the cylindrical slide activity is mounted on the mounting hole of casing for the termination of the rotating shaft,
The cylindrical slide is provided with the briquetting of counterbore and lid on the counterbore in the other end, pull bar is provided with the counterbore and is passed through
The push rod of the pull bar, one end of the push rod abuts against with the bottom surface of the counterbore, and the other end of the push rod passes through roundlet
Nut check is on the pull bar；The pull bar sequentially passes through the end cap that the briquetting and lid are located on the mounting hole, described
Pull bar is by great circle nut check on the end cap.
In above-mentioned axial interval regulator technical scheme, more specifically technical scheme can also be：The pull bar has
The location division abutted against with the briquetting inner face and the rod body part for linking the location division, the rod body part is by being located at thereon
Thread segment be threadedly coupled with the end cap；The spiro rod section being connected with the pull rod screw is provided with the push rod.
Further：The cylindrical slide activity is in the mounting hole.
By adopting the above-described technical solution, the present invention has the advantages that compared with prior art：1st, needs are worked as
Cylindrical slide move right adjustment rotating shaft axially mounted gap when, big round nut and small round nut are unscrewed first, then rotate
Pull bar makes its micro-shifting to the right, and subsequent rotating push rod makes it promote cylindrical slide to move right, and makes push rod and the mutual pretension of pull bar,
The axially mounted gap in counterbore is eliminated, by draw lever locking, screw up with a wrench the big round nut that then screws up with a wrench small round nut
Push rod is locked, device is improved in the operating stability of machine, left tune is similarly；Axially mounted gap adjustment is carried out in countershaft
In, it is not necessary to mounted part is dismantled, as long as large and small two round nut is unscrewed, according to actual conditions rotating push rod and drawing
Bar, it is possible to be adjusted to axially mounted gap, it is convenient, fast；2nd, push rod and the mutual pretension of pull bar, can be push rod, drawing
Bar, cylindrical slide regard a fixed entirety as, so can more fully demonstrate the stepless property adjusted by screw thread pair, it is ensured that assembling
Error is smaller, is that machine provides good condition in follow-up operation.
Brief description of the drawings
Fig. 1 is the scheme of installation of rotating shaft shaft end in existing machinery equipment.
Fig. 2 is the structural representation of the embodiment of the present invention.
Specific embodiment
Below in conjunction with accompanying drawing, the invention will be further described：
Axial interval regulator as shown in Figure 2 includes rotating shaft 1, and the termination of the one end of rotating shaft 1 is filled by two bearings 2
In one end of cylindrical slide 4, the activity of cylindrical slide 4 is in the mounting hole of casing 5, and the cylindrical and casing 5 of cylindrical slide 4 is circular
Mounting hole be that gap coordinates, move axially in mounting hole in order to its cylindrical slide 4 and radial direction assembly precision；Slided in cylindricality
The other end of block 4 is that lateral ends are provided with the briquetting 6 of counterbore and lid on the counterbore, and the briquetting 6 is fixed by sunk screw
On cylindrical slide 4；Cylindrical slide 4 counterbore built with pull bar 8 and the push rod 9 for installing pull bar 8, pull bar 8 has and pressure
Location division 8-1 and the rod body part of link location division 8-1 that the inner face of block 6 is abutted against, screw thread is provided with the lateral ends of rod body part
Section, is provided with axial screwed hole in rod body part；The thread segment being threadedly coupled with the screwed hole of pull bar 8 is provided with push rod 9；Draw
The rod body part of bar 8 sequentially pass through briquetting 6 centre bore and lid mounted in mounting hole upper end cover 7 screwed hole, end cap 7 by bolt with
Casing 5 is connected；Equipped with the big round nut 10 abutted against with the end face outside of end cap 7 in the rod body part of pull bar 8, pull bar 8 passes through great circle
Nut 10 is locked on end cap 7；One end of push rod 9 abuts against with the bottom surface of counterbore, and the other end of push rod 9 passes through small round nut 11
It is locked on pull bar 8.
When need cylindrical slide 4 move right adjustment rotating shaft 1 axially mounted gap when, first big round nut 10 and small
Round nut 11 is unscrewed, then rotating rod 8 makes its micro-shifting to the right, and subsequent rotating push rod 9 makes it promote cylindrical slide 4 to move right,
Axially mounted gap is eliminated, the big round nut 10 that then screws up with a wrench locks pull bar 8, the small round nut 11 that screws up with a wrench will be pushed away
Bar 9 is locked, and left tune is similarly；In countershaft 1 carries out axially mounted gap adjustment, it is not necessary to dismantle mounted part, only
Large and small two round nut is unscrewed, according to actual conditions rotating push rod and pull bar, it is possible to axially mounted gap is carried out stepless
Adjustment, it is ensured that rigging error is smaller, is that machine provides good condition in follow-up operation.
