Description
Technical field
It the utility model is related to worm-drive, and in particular to the generic inspection frock of large-scale worm gear.
Background technology
Worm-drive at present is widely used in the transmission of the industries such as metallurgy, automobile, mine, lathe, turning facilities, center
Away from the large-scale worm gear more than 500mm in the past more by external manufacturer production, with the lifting of domestic production designed capacity, over entering year
Production domesticization has been done step-by-step in large-scale worm gear.But when substituting external product, worm gear produces usually as loose mail, is not having
On the premise of casing trial assembly running-in, increase worm gear and use the live successful difficulty that once changes the outfit in user.This requires snail
Wheel set manufacturer designs production testing frock, meshing mark and sideshake for detecting worm gear etc., improves the exchange of product
Property and reliability.
Following defect be present in structure in traditional worm gear inspection man：1st, a set of frock is only used for a kind of centre-to-centre spacing snail
The inspection of wheel set, for the large-scale worm gear of single and mini-batch production, multicenter away from specification, more set frocks need to be prepared；2nd, large-scale worm gear
Pair examines frock manufacturing cost higher and mostly disposable, causes to waste.
The content of the invention
The purpose of this utility model is：A kind of generic inspection frock of large-scale worm gear is provided, improves and examines frock
Repeat usage, the quantity of frock is reduced, realize that inspection man is general in the range of one section of centre-to-centre spacing, reduce large-scale worm gear
Examine the manufacturing cost of frock.
Technical solution of the present utility model is：The worm gear generic inspection frock include pedestal, worm screw, worm gear, partially
Mandrel bearing sleeve and technique wheel hub, an axle sleeve is installed respectively at the bearings at both ends step of worm screw, worm screw is arranged on base by axle sleeve
In the bearing block of seat, and axle sleeve is fixed on bearing block with axle bumper and baffle plate, eccentric shaft bearing sleeve is installed on pedestal, technique wheel hub
It is arranged on by rolling bearing in eccentric shaft bearing sleeve, using bolt and nut connection worm gear, technique wheel hub and worm gear on technique wheel hub
Inner hole, worm engaging worm gear, it is monolithically fabricated large-scale worm gear generic inspection frock.
Wherein, axle sleeve external diameter is fixed, and its diameter of bore determines according to the bearing step dimension of worm screw, and is moistened in interior hole machined
Oil groove.
Wherein, the external diameter of eccentric shaft bearing sleeve and diameter of bore are fixed, and inner eccentric holes amount is true according to the needs of frock centre-to-centre spacing
It is fixed.
The utility model has advantages below：
1st, the pedestal and bearing block of fixed dimension are designed, pedestal and bearing block form simple casing, pass through the internal diameter of axle sleeve
The installation of more specification worm screws is realized in conversion.
2nd, combined by technique wheel hub with worm gear, realize the installation of more specification worm gears, then pass through dismountable capacity eccentric bearing
Set ensures more specification worm gear centre-to-centre spacing.
3rd, bearing block and the simple casing of pedestal composition worm gear, the high box sizes of manufacturing cost are immobilized, used
Make different centre-to-centre spacing worm gears.
4th, worm screw is supported using axle sleeve, and the rotation of worm screw is realized in inner hole of shaft sleeve design oil-way.
5th, coupled using technique wheel hub with worm gear, and a rolling bearing is installed and is used to undertake worm gear deadweight, and convenient rotation
Turn.
6th, use of the multicenter away from worm gear is realized using the structure of the setting-up eccentricity bearing holder (housing, cover) on pedestal.
7th, it is simple in construction, it is easy for installation, the inspection demand of large-scale worm gear can be effectively realized, and improve inspection frock
Repeat usage, significantly reduce the manufacturing cost that more specifications examine frocks.
Brief description of the drawings
Fig. 1 is the generic inspection tool structure schematic diagram of large-scale worm gear.
Fig. 2 is Fig. 1 schematic top plan view.
In figure：1 bearing block, 2 pedestals, 3 worm screws, 4 worm gears, 5 eccentric shaft bearing sleeves, 6 technique wheel hubs, 7 rolling bearings, 8 bolts
Nut, 9 axle sleeves, 10 baffle plates, 11 axle bumpers.
Embodiment
As shown in Figure 1, 2, the worm gear generic inspection frock includes pedestal 2, worm screw 3, worm gear 4, eccentric shaft bearing sleeve 5 and work
Skill wheel hub 6, an axle sleeve 9 is installed at the bearings at both ends step of worm screw 3 respectively, and worm screw 3 is arranged on the axle of pedestal 2 by axle sleeve 9
In bearing 1, and axle sleeve 9 is fixed on bearing block with axle bumper 11 and baffle plate 10, eccentric shaft bearing sleeve 5 is installed on pedestal 2, technique wheel
Hub 6 is arranged in eccentric shaft bearing sleeve 5 by rolling bearing 7, couples worm gear 4, technique wheel using bolt and nut 8 on technique wheel hub 6
Hub 6 and the inner hole of worm gear 4, worm gear 4 engage worm screw 3, are monolithically fabricated large-scale worm gear generic inspection frock.
Wherein, the external diameter of axle sleeve 9 is fixed, and its diameter of bore determines according to the bearing step dimension of worm screw 3, and in interior hole machined
Oil-way.
Wherein, the external diameter of eccentric shaft bearing sleeve 5 and diameter of bore are fixed, and inner eccentric holes amount is true according to the needs of frock centre-to-centre spacing
It is fixed.
The inspection of the frock is as follows using process：First, axle sleeve 9 is selected according to the bearing step dimension of worm screw 3 to be checked；So
Afterwards, selected eccentric shaft bearing sleeve 5 is needed according to frock centre-to-centre spacing；Then, worm screw 3 to be checked and worm gear to be checked 4 are installed in place；Most
Afterwards, worm screw input two screws of spindle nose are borrowed and loads onto screw, then with crow bar rotary worm, worm gear is loaded onto in inspection man
Rotation, complete to examine.
