Gearbox Assembly Order

Prior to assembly, inner cavity of reducer is thoroughly cleaned and covered with oil-resistant paint.

Assembly is performed in accordance with gearbox assembly drawing, starting from shaft assemblies.

Ball radial bearings pre-heated in oil to 80100 ° C are fitted on the drive shaft. The high-speed shaft is placed in the gearbox housing.

Key is put into intermediate shaft and gear wheel is pressed to rest against shaft collar. Bushing and ball radial bearings preheated in oil to 80100 ° С are fitted on shaft.

Key is laid in slow-moving shaft. Gear cylindrical wheel is pressed on it to rest against shaft collar. Bushing and ball radial bearings pre-heated in oil to 80100 ° C are fitted, stop rings are installed. Then we lay the key.

The assembled shafts are laid in the base of the reduction gear case and put on the cover of the case, covering the surfaces of the joint of the cover and the case with alcohol varnish. For alignment, a cover is installed on the body using two cylindrical pins; bolts attaching the cover to the housing are tightened.

Cuffs are laid in grooves before installation of through covers.

By turning the shafts there is no jamming of bearings (shafts must be turned by hand) and the covers are bolted.

Then, trigger oil with gasket and oil indicator are screwed in.

Oil is poured into housing and inspection hole is closed with cover with gasket made of technical cardboard; cover is bolted. The assembled gearbox is rolled and tested on the bench according to the program set by the specifications.
