ENTIRE OR PARTIAL RECOVERY OF COGS OF GEAR WHEELS AND CROWN - WHEELS  

  The developed company technology allows full recovery of the profile of cogs after their wear resulting from exploitation.
  There is possibility for partial or general wear of broken cogs.
  Surfaced welding is done in an electric arc way through electrodes or semi automatic through wire upon full before repair defectoscopic control for defects /pores, cracks etc../.
  Possibility is given for choice of the hardness of surface layer of 30-43 HRC.


WEAR COGS OF GEAR  WHEEL  Through a specially made portable machine tool grinding is performed of the cog profile towards its module and geometry which eliminates the expensive operation on cog - cutting.
  For application of the technology, there is no limitation in dimensions of gear wheels and crown - wheels.
  The company disposes of mobile group which performs recovery and grinding of borken off and defected cogs in place.






CROWN - WHEEL OF MILL  APPLICATION:
  - crown - wheels of cement mills, kaolin etc.;
  - pressure gear wheels of excavators;
  - crown wheels of the rotation of excavators and diggers.

  The given technology is practically applied and successfully tested at recovery of gear wheels of excavators of Devnya Varovik village of Chernevo, quarry of Kremikovtsi AD etc., this technology is also used at recovery of crown - wheel of mill for kaolin of Kaolin AD town of Senovo.

  More substantial repairs performed:
  - Recovery of broken down gear wheels /diametere 2.3 / for tension drum of excavators E-5 Plant for extraction of lime village of Chernevo Devnya; Mine output plant Balsha private JSC Novi Iskar;

  - Recovery of crown - wheels for the motion of excavators and SKODA;
  - Recovery of worn out and broken off cogs of pinion and rack of excavators E-5 /Plant for extraction of lime village of Chernevo Devnya/;

   Attention!
- For all recovered cogs /wholly or partially/, racks or crowns, Remtechnology LTD gives a minimum of 1 /one/ year of guarantee. For an entirely recovered pressure gear wheels -5 the company gives 2 /two/ years of guarantee.
- Any recovered cog considerably surpasses by wear durability, hardness, toughness and stability to crack formation similar cogs obtained by technology through casting, cog cutting and thermal process.
- The resource of details with wholly recovered cogs under the stated technology towards originals obtained through casting, cog cutting and thermal processing is 2 4 times greater.
- Each cog is checked with control template as its deviation has to be within the limits up to +/-0.3 mm /varying to the dimensions of the wheel and its module/. Obligatory before starting repair, calculation and check is made for allowable loading of cog towards the obtained practical profile of cog after grinding
