6. Gusset stays (bars)

Gusset stays which secure the stationary frame, bed or bed with blocks are always the object of attentive watching of the maintaining watch personnel-watch engineers and watch motormen, namely:

Vibration, which is constantly present at the diesel running at the nominal and alternating regimes at the revolutions (from minimum till nominal revolutions) this testing acts on the rate of lubricating clearances in main and bottom-end bearings of the diesel crankshaft, acts relation between the blocks planes (bed) and stationary frame plane which is resulted in reducing the gusset stays tension and vibration is increasing, and also its ruined force, it appears not identity in gusset stays tension and vibration dynamics acts on main bearings, which are cracked, the white metal is chipping, and diesel crankshaft main journals are ruined due to rubbing of the crankshaft steel on the main bearing bushing steel, as white metal is worn by vibration and circulating oil pressure washed out.

Conclusion

During each preventive repair work (on running out the diesel motor sources), emergency, running and others – it’s necessary to check the identity of gusset stays tension according to the instructions on diesel maintenance and normal tightening of fundamental bolts by dynometric or hydraulic wrenches depending on the diesel power.

1. Check constantly crank web clearance of the crankshaft and keep the regulations on ship’s internal combustion engines maintenance and instructions on diesel-making plants maintenance and not to exceed 1/10000mm from the rating of the given ship’s diesel piston stroke.

Technical conditions:

1. Instructions on MAN ship’s diesels maintenance – German diesel – making firm on diesels.

2. Instructions on BxW ship’s diesels maintenance. Danish diesel – making firm on ship’s diesels.

3. Instructions on Miliz ship’s diesel maintenance. English diesel-making firm on ships diesels.

Necessary units of measures from the international system (single system of designing documentation).

1. N – power making the body 1 kg mass be accelerated – 1 m/p² at the direction of force acting.

2. 1 kg p. = 9.80665 N

3. Pa – pressure, caused by the power of 1N, equally distributed on the surface of 1m².

1 kg p/cm² = 81.10⁴Pa = 10.33 m

1 kg c/cm² = 10.33 m вод. ст. = 10.33 m w h (head)

1 kg c/cm² = one mega Pa = 1 mgPa

1 bar = 1 ks/cm²

Joule = job performed at the transference of the points applying of force of 1N at the distance of 1m at the direction of force action.

Watt (Wt) - power at which the job in one joule is occurred for 1 sec.

Kg-force-meter (kgfm) – job of performed force in 1 kg at the distance of 1m.

1 kgfm = 9.80665 J

Kwt/h – job perfomed for 1 hour by equipment of 1 kwt power.

1 kwt = 1.36 h.p. (horse-power)

1 h.p. (horse power) = 735.449 wt >> 0.736 kwt

Kilogram-force-meter per second (kgfm/s – power at which job is done by the force of 1 kg at the distance of 1 meter for 1 second)

1 kgfm/s = 9.81 wt
