Abstract
The utility model provides a large shaft sleeve mounting and centering device, which comprises a guide rod, a guide sleeve, a support ring, a fixing bolt, an adjusting bolt and a stop block; one side of the guide rod is provided with threads, the other side of the guide rod is provided with a hexagonal square head, the front part of the guide sleeve is welded with a support ring, bolt holes are uniformly distributed in the outer circumferential part of the support ring, the stop dog is fixed on the support ring through a fixing bolt, and adjusting bolts are arranged in the bolt holes uniformly distributed along the radial direction of the support ring. The utility model discloses can guarantee that the flange axle sleeve can be rapidly aligned when the motor shaft after the heating, shorten axle sleeve installation time, guarantee the reliability of whole installation.
Description
Technical field
The utility model belongs to mechanical equipment of steel rolling field more particularly to a kind of large-scale axle sleeve installation centralising device.
Background technique
Currently, rolling mill for hot rolled planks and strips transmission system is generally by main driving motor, transmission shaft and load, (steel rolling equipment is to roll
Roller) composition, it is connected by flange shaft sleeve with tiger's jaw sliding block between transmission shaft and main driving motor.Wherein flange shaft sleeve and motor shaft it
Between using no key be interference fitted connect.
The torque that band mill especially heavy plate mill main shaft is born is higher, is typically designed operation torque
5730kNm, so high driving torque require the magnitude of interference between flange shaft sleeve and motor shaft larger, it is typically designed as 1.2~
1.5mm.It is hot charging that this connection type and application, which generally require assembly method,.Depending on the site environment not with execution conditions
Together, the pre- allowance of flange shaft sleeve diameter of bore is also different.The scene of certain Thick Plate Plant main driving motor flange shaft sleeve and motor shaft
Assembly.Its bottom bracket axle maximum gauge is 1750mm, diameter of bore 800mm, and magnitude of interference is 1.5mm between motor shaft.Scene
Flange shaft sleeve can only be hung to motor shaft side by crane, and axle sleeve after heating, which is packed into motor shaft process, can only lean on other hanging beams and manually
Chain hangs realization, and assembled in situ difficulty is larger.When hot charging, severest consequences are exactly that the workpiece after heating is being not mounted to predetermined bits
Cooling meat when setting is held tightly immovable after being inserted in part.When assembled in situ, key is the centering of axle sleeve and axis center, because
How this guarantees that the accurate centering in axle sleeve and axle center becomes the matter of utmost importance installed for large-scale axle sleeve.
Summary of the invention
The utility model be intended to provide when a kind of certifiable flange shaft sleeve is packed into motor shaft after the heating can rapid centering, contracting
The large-scale axle sleeve of short sleeve set-up time installs centralising device.
For this purpose, the technical solution that the utility model is taken are as follows:
A kind of large size axle sleeve installation centralising device, including flange shaft sleeve, contain guide rod, guide sleeve, support ring, fixed spiral shell
Bolt, adjustment bolt and block；Guide rod side has screw thread, and the other side is machined with hexagonal square toes, and the welding of guide sleeve front has
The circular ring shape support ring of cut-out openings, support ring excircle edge are evenly equipped with bolt hole, and block is fixed on branch by fixing bolt
On pushing out ring, adjustment bolt is equipped with along the bolt hole of support ring radial equipartition.
The utility model has the following beneficial effects:
The utility model can guarantee energy rapid centering when flange shaft sleeve is packed into motor shaft after the heating, when shortening axle sleeve installation
Between, guarantee the reliability of whole installation process.In the enough situations of experience, the heating temperature of flange shaft sleeve can be suitably reduced,
Shorten entire assembly time.
Detailed description of the invention
Fig. 1 is centralising device partial cutaway view；
Fig. 2 is centralising device guide sleeve and support ring combination of side view.
In figure: guide sleeve 1, support ring 2, block 3, fixing bolt 4, guide rod 5, adjustment bolt 6, bolt hole 7, hollow hole
Hole 8.
Specific embodiment
By attached drawing as it can be seen that the utility model large size axle sleeve install centralising device, including guide sleeve 1, support ring 2, block 3,
Fixing bolt 4, guide rod 5 and adjustment bolt 6；5 side of guide rod has screw thread, and the other side is machined with hexagonal square toes, in order to
Guide rod 5 screws in motor shaft ends threaded hole.The front welding of guide sleeve 1 has the circular ring shape support ring 2 of cut-out openings 8, branch
The excircle edge of pushing out ring 2 is evenly equipped with 4 bolts hole 7, and block 3 is fixed in support ring 2 by fixing bolt 4；Along support ring 2
Radial equipartition 4 bolts hole in be equipped with adjustment bolt 6.Should ensure that when processing guide sleeve 1 centre bore and support ring 2 it is outer
Circle is coaxial.
Guide rod 5 is screwed in motor shaft ends threaded hole by spanner.Flange shaft sleeve will after being heated to required size
Guide sleeve 1 and 2 component of support ring are mounted on the inner hole of flange shaft sleeve end, adjust guide sleeve 1 by block 3 and adjustment bolt 6
It is consistent with 2 component center of support ring and flange shaft sleeve center.Then mounting flange axle sleeve, 5 length of guide rod can guarantee in flange
Axle sleeve touches guide sleeve 1 before touching motor shaft.
