It is more simple better, and at present when dismantling Vertical Mill device reducer structure, it is necessary to all parts once to be removed from top to bottom, during maintenance
Between long, most maintenance needs depot repair.
The content of the invention
The present invention provides a kind of vertical mill decelerator spiral bevel gear quick-disassembly structure, solves prior art Vertical Mill decelerator knot
The problem of structure is complicated, and particularly spiral bevel gear dismounting difficulty causes maintenance to be wasted time and energy.
The present invention is achieved through the following technical solutions：
A kind of vertical mill decelerator spiral bevel gear quick-disassembly structure, including lower box, upper box, the height being rotationally connected with lower box
Fast axle and the output flange being rotationally connected with upper box, the high speed shaft are rotationally connected with support sleeve, the support shaft
Set is fixedly connected on lower box, and top bracket and bottom bracket, top bracket and downside are fixedly connected with the lower box
Sprocket drive spindle and barreled tooth flank axle are rotatablely connected on support, barreled tooth flank axle is connected with gear spindle drive, wherein, gear shaft and high speed shaft
Drive connection, barreled tooth flank axle are connected with output flange.
Further improvement project of the invention is that the top surface of the top bracket is in contact with lower box；The bottom bracket
Top surface be in contact with lower box.
Further improvement project of the invention is that the axis of the high speed shaft is horizontal；The axle of the output flange
Line is in vertical position.
Further improvement project of the invention is that the gear shaft is connected by bevel gear pair and high speed shaft；The drum
Shape tooth axle is provided with gear, and the gear engages with the gear in the middle part of gear shaft.
Further improvement project of the invention is, the top of the barreled tooth flank axle passes through drum-shaped tooth type after passing through top bracket
Shaft coupling is connected with sun wheel shaft.
Further improvement project of the invention is that gear ring is provided between the lower box and upper box, gear ring respectively with it is upper
Casing and lower box are fixedly connected, and sun gear is connected by planetary gear and gear ring；The output flange and planet carrier phase
Even, planetary gear is on planet carrier；I.e. power inputs from sun gear, is output to output flange from planet carrier, gear ring is locked.
The present invention compared with prior art, has the following advantages that：
1st, the present invention is compact-sized, and dismounting is simple, and particularly Vertical Mill decelerator is easiest to the high speed level bevel gear peace to go wrong
The secondary dismounting of row shaft gear, it is not necessary to torn open from top to bottom by traditional structure, eliminate dismounting output flange, thrust bearing shoe valve, upper bracket
It is time saving and energy saving Deng the parts of hardly possible dismounting；The use of scene is being operable, decelerator need not return to manufactory and be repaired,
Maintenance cost is low, and the cycle is short；
When the 2nd, dismantling, the attachment screw of support sleeve and nowel body support frame is first unclamped, extracts high speed shaft out, then, then takes downside apart
Support, you can bevel gear pair is changed in maintenance；If the other parts such as gear shaft and barreled tooth flank axle are changed in maintenance, then take apart
Top bracket, gear shaft is taken out with barreled tooth flank axle together with top bracket, convenient disassembly in maintenance process.
