To install the bracket to the propeller shaft made from solid wood Prototype shaft in bracket bushing size in the center of the roller drill a hole 3 mm in diameter. Moving the bracket is out to scab passes through a hole in the shaft with the same layout radial clearance. After this bracket fixed to the final by placing its support impregnated canvas with red lead.
Similarly, using a mock roller set and stern tubes. Ream the hole for it in the keel up to the final size is better, not immediately after pre-alignment of the string. Initially, it is possible to make a hole with a diameter of 5-10 mm less; it will provide an opportunity for centering the tube move in any radial direction within tolerances. First, the alignment is using a mock roller. Wearing roller on a stretched string, drilled by its size keel. Then put on the roller tube.
Centering bearings also carried out on targets, with mock-rollers.
Alignment of the engine to produce more convenient to install it in an enclosure with base frame. Here's how. Collected at two axial (angular cross section, for example) and several cross-beams base frame mounted engine. By the terminal cross-beams base frame fastened flaps with glued plywood sheets of drawing paper - on the side facing the engine. To ratchet and flywheel firmly tied pencils, which when you turn the motor shaft is drawn on Whatman paper circles.
Take off the engine with the base frame, and the very foundation frame. Find the centers of the circles on the sheets and drill holes for them of 3 mm diameter. Next, moving the base frame, seeking a position that the string will pass through the centers of these holes. Then attach the base frame by bolts and set the engine on it.
On planning boats, so as not to remove the engine in the nose has to install propeller shaft to break it to the vertical plane. When using the hinged joints of the shaft assembly is simplified.
It is very convenient for mounting bracket with tilt axis of the propeller shaft relative to the bottom of the boat. When mounting bracket to attach the first base on a screw. Spur of the displacement during operation prevents the pin boat. Facilitates alignment and stuffing box, flexibly attached to the metal casing of the shaft, which is mounted on the bottom, or to the tube. Through this connection offset errors mounting shaft. In addition, this type of engine installation on a good shock absorbers. |
