Abstract
The invention discloses an axial gap adjusting device and belongs to the machinery equipment manufacturing technical field. The axial gap adjusting device comprises a rotating shaft; an end head of the rotating shaft is installed at one end of a cylindrical slider through a bearing; the cylindrical slider is movably arranged in a mounting hole of a shell; the other end of the cylindrical slider is provided with a counterbore and a pressing block covering the counterbore; a pull rod and a push rod passing through the pull rod are arranged in the counterbore; one end of the push rod abuts against the bottom surface of the counterbore; the other end of the push rod is locked on the pull rod through a small round nut; the pull rod passes through the pressing block and an end cover which covers the mounting hole sequentially; and the pull rod is locked on the end cover through a large round nut. Compared with the prior art, the axial gap adjusting device of the invention can assist in conveniently and quickly adjusting the axial gap of the rotating shaft.
Description
Technical field
The present invention relates to plant equipment manufacturing technology field, especially a kind of device raising whole end play for rotating shaft.
Background technology
The rotating shaft of plant equipment, in assembling, often needs the thickness adjusting bearing gasket between bearing face and bearing cap to carry out the axial assemblage gap of rotating shaft; A kind of rotating shaft 10 as shown in Figure 1, this rotating shaft 10 is contained on cylindrical slide 40 by the bearing 20 being installed on its two ends, and cylindrical slide 40 is connected with casing 50 by bolt; Bearing gasket 30 is provided with between the left side and the bearing gland end of cylindrical slide 40 of bearing 20 outer ring.During installation, first the thickness of bearing gasket by calculated value is installed, now there will be the phenomenon that bearing gasket is thick or thin, therefore, according to after multiple Assembly of the parts, by the thickness of actual measurement rigging error adjustment bearing gasket, must install next time; But need the part dismantled more in a pre-installation, original installation accuracy can not be ensured after installation, therefore can not ensure again to install and just can control rigging error in allowed band, sometimes need dismounting repeatedly just can complete adjustment; Being dismounted for multiple times can destroy dead eye dimensional accuracy, thus affects installation accuracy, and production efficiency is low.
Summary of the invention
Technical matters to be solved by this invention is to provide a kind ofly can carry out the axial interval regulator of end play adjustment by countershaft quickly and easily, during to solve existing installation rotating shaft bearing gasket thickness must repeated disassembled and assembled, adjust the problem that could determine.
The technical scheme that technical solution problem of the present invention adopts is: this axial interval regulator includes rotating shaft, the termination of described rotating shaft is contained in one end of cylindrical slide by bearing, described cylindrical slide activity is contained on the mounting hole of casing, described cylindrical slide is provided with counterbore in the other end and mounts cover the briquetting on this counterbore, pull bar and the push rod through described pull bar is provided with in described counterbore, one end of described push rod and the bottom surface of described counterbore abut against, and the other end of described push rod passes through roundlet nut lock on described pull bar; Described pull bar is successively through the end cap that described briquetting and lid are located on described mounting hole, and described pull bar passes through great circle nut lock on described end cap.
In above-mentioned axial interval regulator technical scheme, technical scheme can also be more specifically: described pull bar has the location division abutted against with described briquetting inner face and the rod body part linking described location division, and described rod body part is threaded with described end cap by establishing thread segment thereon; Described push rod is provided with the spiro rod section be connected with described pull rod screw.
Further: described cylindrical slide activity is contained in described mounting hole.
Owing to have employed technique scheme, the present invention compared with prior art has following beneficial effect: 1, when need cylindrical slide move right adjustment rotating shaft axial assemblage gap time, first large round nut and little round nut are unscrewed, rotating rod makes it micro-ly move to the right again, rotating push rod makes it promote cylindrical slide to move right subsequently, and make push rod and the mutual pretension of pull bar, eliminate the axial assemblage gap in counterbore, then large round nut is screwed up with a wrench by draw lever locking, push rod is locked by the little round nut that screws up with a wrench, improve device in the operating stability of machine, left tune in like manner, carry out in axial assemblage gap adjustment at countershaft, do not need to dismantle mounted part, as long as large and small two round nuts are unscrewed, according to actual conditions rotating push rod and pull bar, just can adjust axial assemblage gap, convenient, fast, 2, push rod and the mutual pretension of pull bar, can be regarded as a fixing entirety push rod, pull bar, cylindrical slide, so more can fully demonstrate the stepless property adjusted by screw thread pair, guarantee that rigging error is less, for machine provides good condition in follow-up operation.
Accompanying drawing explanation
Fig. 1 is the scheme of installation of existing machinery equipment shaft axle head.
Fig. 2 is the structural representation of the embodiment of the present invention.
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, the termination of rotating shaft 1 one end is contained in one end of cylindrical slide 4 by two bearings 2, cylindrical slide 4 activity is contained in the mounting hole of casing 5, the cylindrical of cylindrical slide 4 and the mounting hole of casing 5 circle are clearance fit, so that its cylindrical slide 4 moves axially and radial assembly precision in mounting hole; Be provided with counterbore at the other end of cylindrical slide 4 and lateral ends and mount cover the briquetting 6 on this counterbore, this briquetting 6 is fixed on cylindrical slide 4 by sunk screw; At the counterbore of cylindrical slide 4 built with pull bar 8 and the push rod 9 installing pull bar 8, pull bar 8 has the location division 8-1 abutted against with briquetting 6 inner face and the rod body part linking location division 8-1, be provided with thread segment at the lateral ends of rod body part, rod body part has axial threaded hole; Push rod 9 is provided with the thread segment be threaded with the threaded hole of pull bar 8; The rod body part of pull bar 8 is successively through center pit and the threaded hole mounted cover at mounting hole upper end cover 7 of briquetting 6, and end cap 7 is connected with casing 5 by bolt; The rod body part of pull bar 8 is equipped with the large round nut 10 abutted against with end cap 7 end face outside, pull bar 8 is locked on end cap 7 by large round nut 10; One end of push rod 9 and the bottom surface of counterbore abut against, and the other end of push rod 9 is locked on pull bar 8 by little round nut 11.
When need cylindrical slide 4 move right adjustment rotating shaft 1 axial assemblage gap time, first large round nut 10 and little round nut 11 are unscrewed, rotating rod 8 makes it micro-ly move to the right again, rotating push rod 9 makes it promote cylindrical slide 4 to move right subsequently, eliminate axial assemblage gap, pull bar 8 is locked by the large round nut 10 that then screws up with a wrench, and push rod 9 is locked by the little round nut 11 that screws up with a wrench, and left tune in like manner; Carry out in axial assemblage gap adjustment at countershaft 1, do not need to dismantle mounted part, as long as large and small two round nuts are unscrewed, according to actual conditions rotating push rod and pull bar, just can carry out stepless changing to axial assemblage gap, guarantee that rigging error is less, for machine provides good condition in follow-up operation.
