Frock is prepared and is installed in fuel reserve tank is installed in the concrete foundation, and this fuel reserve tank is reserved through hole with the center of platen and linked to each other; The oil-out of said fuel reserve tank and Hydraulic Station pipeline connection, whole oil circuit loop is in complete sealing state; Be equipped with in fuel reserve tank bottom adjustable float top down, with the last top supporting location on the tailstock tool; Said top and following top center line is the axis of rotation of platen;
Workpiece be installed adjustment to preprocessing increase, the clamping of the Super Long-axles gear of reductor transmission device, open the seal cover on the work top, the Super Long-axles gear is put into the centre bore of workbench; Adjust that centre bore aligns under adjustable float top down and the shaft gear; To go up the top centre bore on the shaft gear that moves to, and play the table check and proofread and correct, after making the shaft gear axle center and the platen axis of rotation overlapping; Clamp the Super Long-axles gear by clamp mechanism, for accurate grinding lays the foundation.
Characteristics of the present invention and the effect that reaches:
(1) technological equipment is improved, can realize that axial length reaches the Super Long-axles gear of 4800mm, solved the present domestic difficult problem that can't process, can satisfy the demand of new product development;
(2) design and installation adjustablely float toply down, and adjustment confirms the inregister of upper and lower top center line and machine tool rotary center line, reduces the gear setting-up eccentricity, can improve the Gear Processing precision; Simultaneously, can reduce the trouble that conventional gear is installed timing, effectively shorten and install correction time, improve operating efficiency.
But through this manufacturing approach Machining of Gear maximum gauge is 2000mm, and axial length is 4800mm, and the diameter of axle is less than overlength, the high accuracy shaft gear of 900mm, and precision can reach the 2-5 level of DIN3962 standard.

The specific embodiment
The manufacturing approach of a kind of overlength, high accuracy shaft gear; This method utilization designs the RAPID 2000 type numerically controlled tooth grinding machines of being produced by German HOFLER company voluntarily, mainly through frock preparation and installation, workpiece be installed adjustment and by the processing route completion to increase, the manufacturing of reductor transmission device; Frock preparation in this method and installation, clamping workpiece set-up procedure realize through following method:
Frock is prepared and is installed in installation fuel reserve tank 8 in the concrete foundation 6, and this fuel reserve tank 8 is reserved through hole with the center of platen 4 and linked to each other; The oil-out 9 of said fuel reserve tank 8 is communicated with Hydraulic Station pipeline 10, and whole oil circuit loop is in complete sealing state; Be equipped with in fuel reserve tank 8 bottoms adjustable float top down 7, with last top 1 supporting location on the tailstock tool; Said top 1 and down top 7 center line is the axis of rotation of platen 4;
Workpiece be installed adjustment to preprocessing increase, the clamping of the Super Long-axles gear of reductor transmission device, open the seal cover on 4 of the workbench, the Super Long-axles gear is put into the centre bore of workbench 4; Adjust adjustable float down top 7 with shaft gear under centre bore align; To go up top 1 and move to centre bore on the shaft gear, and play the table check and proofread and correct, after making the shaft gear axle center and the platen axis of rotation overlapping; Clamp Super Long-axles gear 2 by clamp mechanism 3, for accurate grinding lays the foundation.
Embodiment 1
The manufacturing approach of a kind of overlength, high accuracy shaft gear, this method are utilized designing technique index voluntarily, and maximum machining diameter is 2000mm, and maximum axial length is 2800mm, workbench diameter 1850mm; Reserve the through hole of φ 900mm at the workbench center; The RAPID 2000 type numerically controlled tooth grinding machines that work top is provided with seal cover and is produced by German HOFLER company, mainly through frock preparation and installation, workpiece be installed adjustment and by the processing route completion to increase, the manufacturing of reductor transmission device; After this method is improved frock preparation and installation, clamping workpiece set-up procedure, but Machining of Gear maximum gauge 2000mm, axial length 4800mm, the diameter of axle is less than overlength, the high accuracy shaft gear of 900mm, and precision can reach the 2-5 level of DIN3962 standard.In the machining manufacture of overlength, high accuracy shaft gear, the frock preparation after the improvement and installation, the workpiece adjustment process that is installed, realize through following step:
