Abstract
The invention discloses a kind of high-pressure diesel electric generating set coupling assembly technologies, and shaft coupling and generator shaft can be made reliably to organize integrally, transmit torque by shaft coupling, prolong its service life.
Description
Technical field
The present invention relates to a kind of high-pressure diesel electric generating set coupling assembly technologies.
Background technique
Incorrect centering will will cause excessive vibration, so as to shorten the bearing and connector of engine and generator
Service life, and be frequently necessary to centering again.
Definition that is centering content and misaligning:
(1) it the parallel centering of axis: when driven equipment is parallel but decentraction with the center line of engine, can generate flat
Row misaligns, and also referred to as hole misaligns；
(2) when the center line of the center line of driven equipment and engine is not parallel, angle can axis angle centering: be generated not
Centering, also referred to as face misalign.
Engine relative axle direction of rotation turn-back trend and driven equipment (generator) in the rotation side of axis
To rotating tendency be exactly reaction torque.It will increase with load naturally, and cause to vibrate.This vibration is in idling
It is imperceptible, but can feel in on-load.This is often as in the case where reaction torque acts on, and pedestal intensity is insufficient and generates
Big pedestal amount of deflection, thus change center line centering and caused by.There are the influences of the centerline deviation of edge-to-edge for this.In engine
When idling (zero load) or shutdown, deviation will disappear.
When engine and generator reach operating temperature, thermal enlargement or thermal expansion are also just with generation.It is simultaneously to vertical
The expansion of straight and horizontal both direction.The expansion of vertical direction produces between component installation foot and their own rotation centerline
It is raw.The size of this expansion is decided by material used, the temperature rise of appearance and from rotation center to the vertical range of installation foot.
Vertical compensation includes that aligning equipment is adjusted to nonzero value.
The thermal expansion of crankshaft horizontal direction extends from the thrust bearing of engine to the other end.Start when being connected to by equipment
It is necessary to considering this thermal expansion when this one end of machine.It is this swollen if driven equipment is bolted to engine cylinder body
Swollen effect is slight, because cylinder body and crankshaft are almost expanded with equal expansion rate.
Level compensating, which can be used one, allows to drive the shaft coupling for making abundant relative motion between driven device.Installation
When equipment, it is considered as the workspace for making horizontal direction thermal expansion enter shaft coupling, without far from shaft coupling workspace.Otherwise, meeting
Cause crankshaft thrust bearing load excessive, and/or damages shaft coupling.If it is considered that making song when engine checks in hot pair
