Abstract

A three-phase asynchronous motor of mining machinery comprises a motor, an oil pump and an engine, wherein the motor and the oil pump are connected through the direct-insertion connection of an oil pump shaft and a motor shaft; a clutch device extends from the blade end shaft of the motor; and the clutch device is connected with the engine. An oil pump installation spigot at the front end cover of the motor and a motor output shaft inner hole have coaxiality; and the center line of the inner hole of the output shaft of the motor is vertical to the front end cover of the motor. According to the utility model, direct-insertion connection is adopted between the motor and the pump, the connection length is reduced, the structure is compact, the mechanical noise caused in the intermediate link is lowered, the mechanical loss is decreased and the efficiency is improved; and at places without a power supply, a diesel generator generates electricity and supplies electricity for the motor and the motor can also be driven by the diesel generator as a power source to rotate. Compared with the prior art, the three-phase asynchronous motor is small in volume, very ingenious to use, low in failure rate, smooth and stable in operation and very remarkable in energy-saving effect.

Description

The mining machinery threephase asynchronous

Technical field

The utility model belongs to mechanical field, is specifically related to a kind of mining machinery threephase asynchronous.

Background technology

The mining machinery market demand is very huge at present; Because mining machinery motor majority operation out of doors; And the place is remote, and some place can not provide three phase mains, and the threephase asynchronous that mining machinery uses has many specific (special) requirements: 1, starting torque requires big; Motor wants to bear the ability of overload in short-term, requires bigger breakdown torque; 2, require environmental protection, guarantee the low vibration of motor, low voice; 3, require motor energy-saving and cost-reducing to greatest extent; 4, because the many dusts of operational environment of mining machinery, the outer operation of multicell, so degree of protection requires height; 5, require to solve mining machinery when ungetable local work, the problem of three phase mains can not be provided; 6, owing to the mine operation limited space, device space position is less relatively, and Structural Design Requirement is compact as far as possible.The motor product that provides in the market all can not satisfy above-mentioned requirements simultaneously.

In the prior art, the common y series motor of the many employings of mining machinery or engineering machinery, exist following not enough: because installing space that need be bigger, equipment volume is bigger, is unfavorable for using in narrow and small relatively work-yard; Common y series motor also exist detent torque low, in short-term overload capability poor, can only the shortcomings such as place use of three phase mains arranged.

Summary of the invention

The purpose of the utility model is to provide the low vibration of ability, motor that a kind of starting torque is big, motor can bear overload in short-term, low voice, can uses the mining machinery threephase asynchronous of hybrid power source.

The technical scheme of the utility model is: comprise motor, oil pump, engine; Connecting between motor and the oil pump is that oil pump shaft goes into to connect with the motor shaft straight cutting; Motor blower fan end shaft extension has arrangement of clutch, and arrangement of clutch is connected with engine.

Said motor front end housing oil pump is installed seam and motor output shaft endoporus axiality, and the motor output shaft inner hole centreline is vertical with the motor front end housing.

The utility model oil pump, motor and Diesel engine integrated design.For guaranteeing compact conformation, motor connects with pump have been cancelled traditional clutch that passes through and has connected, thus since clutch connect and produce mechanical shock and produce mechanicalness noise; Improve and adopt straight cutting to go into to connect, promptly oil pump shaft directly inserts in the motor output shaft, reduces syndeton length on the one hand; Make compact conformation; The mechanicalness noise of cutting down the number of intermediate links on the other hand and producing has also reduced mechanical loss, raises the efficiency.The utility model is designed with arrangement of clutch in motor blower fan end shaft extension and is connected with Diesel engine, in the place that does not have power supply, is generated electricity to the motor power supply by diesel engine generator, also can use Diesel engine to drive the motor rotation as power source.Because motor is an axis rotation, when work, can not be with the diesel engine generator rotation, must when work, throw off diesel engine generator, the arrangement of clutch of the utility model can reduce the machine operation load like this, effectively utilizes thereby improve electric efficiency.With Diesel engine during as power then arrangement of clutch close, work through the motor shaft drive load.Structural design is compact, is convenient to mining machinery in the narrow space operation.

Compared with prior art, the utility model equipment volume diminishes, and uses very dexterity, and rate of breakdown reduces, operates steadily, and energy-saving effect is also fairly obvious.
