Abstract
The present invention is to repair the restorative procedure that the travelling gear root of ball mill size under cut is cut, preparation：Workbench, hand grinder, new little gear tooth block；Model is processed with 2mm aluminium sheets milling machine.Restorative procedure：Pinion shaft is hung on workbench, it provided with arc length is 4mm circular grooves that grinding wheel is cylindrical on hand grinder, circular groove coincide with the new convex circular-arc tooth surface in little gear top, grinding wheel circular groove is placed on the convex circular-arc tooth surface of pinion head, hand grinder is opened to pull back and forth, to tooth top flange, burr and the high convex circular-arc tooth surfaces of tooth top of 4mm are ground, side broken is detected with tooth block, until the ground flank of tooth and tooth block are similar, flanging burr is ground off, repair a tooth, rotation pinion is to second tooth, change new grinding wheel, repeat above-mentioned, a to the last tooth reparation, clean the flank of tooth, lift up into installation, repair time is 46 hours, extend little gear to use 36 months.This travelling gear, which repairs the restorative procedure cut of root, has that repair time is fast, extends little gear service life, reduces production cost.
Description
Technical field
The restorative procedure that the travelling gear root cut the present invention relates to the big pinion drive fatigue generation root of ball mill is cut.
Background technology
Thermal power plant at present, in the big pinion drive of open type of the ball mill in ore dressing plant, because little gear use it is certain
Time little gear involute, which can be worn, becomes straight line, destroys the engagement of gear, and the root for forming little gear top digging gear wheel root is cut now
As impact sound can be sent by destroying gear engagement.Traditional restorative procedure is that replacing little gear or little gear turn-over use, and this method is repaiied
Multiple time length, is also wasted.
The content of the invention
In order to quickly repair under cut, it is an object of the invention to provide the restorative procedure that a kind of travelling gear root is cut.
Restorative procedure of the present invention is：Preparation：Workbench, hand grinder, new little gear tooth block；Model is used
2mm aluminium sheets milling machine is processed.Restorative procedure：Pinion shaft is first hung into workbench, grinding wheel is cylindrical on hand grinder is provided with arc
A length of 4mm circular grooves, circular groove coincide with the new convex circular-arc tooth surface in little gear top, and grinding wheel circular groove is placed on small
On the convex circular-arc tooth surface of gear teeth tips, open hand grinder and pull back and forth, to tooth top flange, burr and the high tooth top domes of 4mm
Curved tooth face is ground, and side broken is detected with tooth block, and until the ground flank of tooth and tooth block are similar, flanging burr is ground
To fall, repair a tooth, rotation pinion to second tooth, change new grinding wheel, repetition is above-mentioned, repairs whole teeth, cleans the flank of tooth,
Installation is lifted up into, repair time is 4-6 hours, extends little gear using 3-6 months.It can go out on little gear top when gear wheel root is cut
Existing flanging burr, this burr is to dig gear wheel tooth root to be formed, as long as so little gear flank of tooth tip circle curved tooth face and burr are ground
It is similar to cut new pinion head circular-arc tooth surface, just can correct involute, eliminates root and cuts, not only can be after by this method reparation
It is continuous to use little gear, repair time is also saved, so as to reach the purpose that the present invention can quickly repair under cut.
The invention has the advantages that can quickly repair under cut extends the little gear life-span.
Brief description of the drawings
The present invention is further described below in conjunction with the accompanying drawings.
Figure is hand grinder grinding little gear schematic diagram of the present invention.
1, little gear 2, hand grinder 2-1, grinding wheel in figure
Restorative procedure is described in detail
First, preparation：1st, workbench is provided with two fulcrum Ge axles；2nd, hand grinder 2, wherein grinding wheel 2-1 need sand
Take turns factory's customization；3rd, new little gear tooth block,
2nd, restorative procedure：1st, the axle of little gear 1 is hung into workbench, axle Ge is on two fulcrums of workbench, Ke Yizhuan
It is dynamic；2nd, customize the cylindrical of grinding wheel 2-1 and be provided with a length of 4mm circular grooves of circular arc, circular groove shape and new pinion gear teeth
Convex circular-arc tooth surface is pushed up to coincide, grinding wheel 2-1 circular grooves are placed on the convex circular-arc tooth surface of pinion head, open portable emery wheel 2,
Pulling back and forth, grinding tooth top flange, burr and the high convex circular-arc tooth surfaces of tooth top 4mm, side broken are detected with tooth block, until
It is similar with tooth block to be ground convex circular-arc tooth surface, a tooth is repaired, rotation pinion, second tooth is gone to, changes new grinding wheel
2-1, above-mentioned reparation whole tooth is repeated, a tooth is repaiied and can guarantee that every dentine amount is the same with one piece of grinding wheel 2-1；3rd, it is clear with kerosene
Wash the flank of tooth, dry；4th, the axle of little gear 1 being lifted up into installation, is driven big little gear because can be ground to the involute of some cycles little gear 1
Damage, produce the Undercutting Phenomenon that gear wheel root is dug mill by the tooth top of little gear 1.Impulsive sound can be produced by destroying steady engagement, can not be run,
This restorative procedure, which uses, is ground flanging burr caused by the tooth top of little gear 1 and the high circular-arc tooth surfaces of tooth top 4mm such as with grinding wheel 2-1
Newly, root is eliminated to cut.It is continuing with 3-6 months.Extend the service life of little gear 1 with repair time fast (4-6 hours), save life
Produce cost advantages.
