Abstract
The utility model relates to a starting device of a medium-speed high-power diesel engine, which comprises a flywheel tooth ring of a diesel engine. The starting device of the medium-speed high-power diesel engine is characterized by also comprising a motor of which the power is 16KW, wherein the flywheel tooth ring is connected with the motor of 16KW by a starting pinion. In the utility model, the high-power motor of 16KW is adopted to start the medium-speed high-power diesel engine. The utility model not only has a simple structure, small floor area and a low cost but also avoids the noise of starting air and the pollution of lubricating oil and is beneficial to purifying the environment.
Description
Technical field
The utility model relates to a kind of middling speed high-power diesel engine, relates in particular to a kind of middling speed high-power diesel engine starting drive.
Background technique
At present, the above high-powered medium-speed diesel engines of 200 cylinder diameters all adopts pneumatic starting.Before the diesel engine starting, air compressor contracts air pressure earlier and is kept in the air bottle, air pressure in the air bottle is general≤3MPa, during diesel engine starting, open valve, connect the starting power of electromagnetic valve, pressurized air arrives reduction valve from air bottle through valve, through behind the reduction valve, air pressure is eased down to 0.8MPa, and has passed moving electromagnetic valve and enter starter motor, starter motor slow-speed under the driving of air pressure, and the flywheel ring gear engagement of stretching out small gear and diesel engine, the motor high speed rotating drives the diesel engine flywheel and rotates, when the diesel engine flywheel reaches catching fire during rotating speed of diesel engine, diesel engine catches fire, this moment, release button started closed electromagnetic valve, and starter motor loses air pressure, small gear breaks away from flywheel ring gear, resets.This diesel engine starting device need dispose equipment such as air compressor, air bottle, complex structure not only, and floor space is big, the cost height, and be not easy to install, also there is the big problem of noise simultaneously.
The model utility content
The purpose of this utility model is to provide a kind of middling speed high-power diesel engine starting arrangement simple in structure.
The purpose of this utility model is achieved in that a kind of middling speed high-power diesel engine starting arrangement, comprises the flywheel ring gear of diesel engine, it is characterized in that; Also comprise the 16KW motor, described flywheel ring gear is connected with described 16KW motor by starter pinion.
Above-mentioned 16KW motor is fixed on the bow-shaped support by cramp frame.
Connect by hexagon head bolt between above-mentioned cramp frame and the bow-shaped support.
The bow-shaped support of above-mentioned 16KW motor is fixed on the diesel engine by hexagon head bolt and cylindrical pin with internal thread.
Above-mentioned bow-shaped support comprises base plate and the arc gusset and the positioning plate that are arranged on the described base plate.
Above-mentioned 16KW motor is provided with installs cylndrical surface and the wiring terminal that is connected storage battery, and above-mentioned starter pinion is fixed on the front end of described 16KW motor by locking nut.
The utlity model has following beneficial effect, the utility model adopts the heavy-duty motor starting middling speed high-power diesel engine of 16KW, and is not only simple in structure, floor space is little, cost is low, and the noise when having avoided air actuation and the lubricant pollution of lubricated air motor, helps environment purification.

Embodiment
Embodiment, a kind of middling speed high-power diesel engine starting arrangement comprises the flywheel ring gear 1 and the 16KW motor 2 of diesel engine, 16KW motor 2 is connected with flywheel ring gear 1 by starter pinion 3; 16KW motor 2 is fixed on the bow-shaped support 5 by cramp frame 4; Connect by hexagon head bolt 6 between cramp frame 4 and the bow-shaped support 5; The bow-shaped support 5 that 16KW motor 2 is installed is fixed on the diesel engine by hexagon head bolt 6 and cylindrical pin with internal thread 7; Bow-shaped support 5 comprises base plate 9 and the arc gusset 10 and the positioning plate 11 that are arranged on the base plate 9; 16KW motor 2 is provided with installs cylndrical surface 8 and the wiring terminal 12 that is connected storage battery, and starter pinion 3 is fixed on the front end of described 16KW motor 2 by locking nut 13.
The working principle of 16KW motor 2 is as follows: switch starter 16 closures, control relay 15 makes contact K2 closure, slow-speed coil 17 and magnetic switch 18, starter pinion 3 stretches out under the electromagnetic force effect and flywheel ring gear 1 engagement, in the process that starter pinion 3 stretches out, driven by motor starter pinion 3 slowly rotates, so that starter pinion 3 is smooth and easy with flywheel ring gear 1 engagement; Simultaneously, main contact 14 meshes, also moves to when magnetic switch 18 puts in place operating position at starter pinion 3 and flywheel ring gear 1, and contact K1 disconnects, and the motor high speed rotating drives the rotation of diesel engine flywheel and reaches the diesel engine starting rotating speed; Switch starter 18 disconnects, and control relay 15 discharges, and K2 disconnects, and magnetic switch 18 discharges, and main contact 14 disconnects, and starter pinion 1 is thrown off with flywheel ring gear 1 simultaneously.
