To install the motor on the basement, you must first make a sketch of its location, position of the shaft and bearings. Then, on the design mark the exit point of the propeller shaft on the keel at this point, drilling a centering hole for the pipe. To avoid mistakes and direction should use sketch, attach the bracket to the keel-guard with a hole to drill. If you have to drill the keel of a very acute angle, it is best to do it with the cutting so that the drill was part of the timber at right angles.
There are two ways the propeller shaft assembly. The first, most simple, is as follows. In accordance with the sketch as accurately as possible, installed pipe. She sets the direction of the axis of the propeller shaft. In a tube inserted into sleeve support bearing and seal, which will continue to strictly fix the position of the propeller shaft.
On the tube is inserted into the shaft wear in turn mount, support and thrust bearings, making sure that there is no sag. Then, using the pads secures the bracket and bearings so that the shaft is rotated easily by hand.
At the foundation beams mark the place of strengthening plates under legs motor.
The engine should be able to move around within the square and to ensure centering.
Alignment of the propeller shaft and the engine output shaft is checked by means of arrows, mounted on the flanges of both shafts. First, turn the flanges so that the arrow at the top were on the same level, then both the shaft is turned by 180 ° and measure the distance between the arrows in this position for height. Measured distance and show the offset in the vertical shaft, which is eliminated by installing shims under the feet of engines. Similarly, the measured horizontal displacement of the shaft, which eliminates engine movement across the foundation gons.
Now it remains to eliminate the possible fracture line of the shaft. To do this, set the hands at the same level, measure the distance between their ends and turning shafts for plumbing to 180 °. Measure the distance between the ends of the arrows. If the distance will be different, it would mean that the line of the shaft has a kink. Eliminate fracture displacement engine |
