Description
Technical field
The utility model relates to the auxiliary slow start device of a kind of high-power gear reducer.
Background technique
At present, the small-power speed reducer generally adopts variable-frequency motor startup, electromagnetic adjustable speed motor startup, star triangle start, high-power gear reducer generally adopts reduced-voltage starting, becomes resistance startup or direct startup etc., high-power gear reducer adopts aforesaid way to start, starting load impacts big, fragile, must increase the speed reducer volume and could guarantee bearing capacity and safety coefficient, increase production and user cost greatly.In addition, comprise also in the prior art that high-power gear reducer adopts soft starting mode, its principle has adopted differential attachment, when main electric motor starting, the differential attachment the other end needs to brake with break, the a large amount of heat energy that produce need to cool off through cooler, waste energy, and have increased a large amount of fitting device, as cooler, Lubricating-oil Station etc., the space that fitting device occupies is equivalent to more than three times of main gear reducer, has reduced the bearing capacity of main frame, and manufacturing is complicated, cost is higher.If high-power gear reducer adopts the high-power frequency conversion electric motor starting, the high-power frequency conversion motor technology is not mature enough at present, and high-power frequency conversion motor cost height, power consumption height, adopts the mode of high-power frequency conversion electric motor starting main gear reducer in all prior aries hardly.
Summary of the invention
Start the problems that exist in order to overcome high-power gear reducer in the prior art, the purpose of this utility model provide a kind of simple in structure, cost is low, reliability is high, start that load is little, long service life, the auxiliary slow start device of high-power gear reducer convenient for installation and maintenance.
The technical solution adopted in the utility model is: a kind of high-power gear reducer is assisted the slow start device, comprise main gear reducer, the assisted deceleration machine, the slow start device, be connected the slow start device between the output shaft of the input shaft of main gear reducer and assisted deceleration machine, described slow start device comprises the flange shell and is located at the interior free wheel device of flange shell, described free wheel device comprises shell, star-wheel, roller, bearing, coupling, star-wheel is set on the main gear reducer input shaft, clutch outer member through Bearing Installation on star-wheel, coupling is set on the assisted deceleration machine output shaft and with clutch outer member and is connected, and roller is installed in the cavity between star-wheel and clutch outer member.
After adopting technique scheme, the beneficial effect that the utility model reaches is:
1, starts main gear reducer by the assisted deceleration machine through the slow start device, make the load of main gear reducer start running from state of rest lentamente, realized the slow start of load, reduced system shock and moment startup load, broken teeth, not damaged do not start and operate steadily reliably, and inrush current reduces greatly, reduce the system failure coefficient that causes when starting, increase substantially Safety performance; Main gear reducer electric motor starting behind the slow start, the slow start device breaks away from automatically, and it is steadily reliable to start the power transition, energy-saving and cost-reducing, makes electrical equipment and mechanical system more stable, has prolonged the working life of system;
2, fill up the blank that high-power gear reducer does not have the high-power frequency conversion electric motor starting, greatly reduced cost;
3, simple in structure, start annex few, take up an area of that the space is little, easy for installation, cost of production is low, makes full use of the mechanical property of material, the performance deficiency that has overcome that the soft starting mode annex is many in the prior art, floor space is big, waste of material is many etc.
