Abstract
Disclosed is an assembled drive unit for an electromotor, which is easy to start up and is used to solve the problem in smooth startup and the problem in reducing coil dissipation during startup. The assembled drive unit comprises an electromotor and a decelerator which are sequentially connected; a two-stage belt gear which is arranged to be an overgear is connected at the rear of the decelerator, wherein the big belt pulley of the first stage gear is connected with the output shaft of the decelerator and the small belt pulley of the first stage gear is coaxial with the big belt pulley of the second stage gear whose small belt pulley is in connection with the load; the decelerator is in retardment arrangement. The belt pulleys and the belts can skid at the time of starting up or in the case of sudden change of the load, thus avoiding over-current or burnout due to that the electromotor fails to bear the load, and meanwhile reducing wear to the circuitry caused by over-current during startup.
Description
Technical field
It is the transmission combination device of driving force with the motor that the utility model relates to a kind of.
Background technique
Motor has obtained widely to use in modern society, particularly in industrial production, and the motor power plant that more are absolutely necessary.The industrial electro motivation runs into overload through regular meeting in use, and the load pulsation is big, short-time overload etc. can cause that motor burns, and causes damage to production.Also have some production processes to need the motor of frequent starting, as blower fan, stirrer, shredder, lift, winch etc., because the inrush current of motor is generally 5-8 times of rated operational current, frequent starting also can cause motor overheating, can bring damage to circuit if motor is in over-current state for a long time, also be easy to burn motor.In addition, bigger inrush current also causes bigger circuit energy consumption.Although in the power supply line of motor, all installed parts such as fus, overcurrent protection additional, can not address the above problem.
Summary of the invention
The utility model is used to overcome the defective of above-mentioned prior art and a kind of electric motor drive composite set that is easy to start is provided.
The technological scheme that addresses the above problem is:
A kind of electric motor drive composite set that is easy to start, comprise motor and retarder in the formation, motor is connected successively with retarder, connect the two-stage belt gear in retarder 2 back, belt transmission is by raising speed transmission configuration, wherein, the big belt pulley 5 of first order driving mechanism is connected with reducer output shaft, small belt pulley 6 is coaxial with second level driving mechanism big belt pulley 7, the small belt pulley 8 of second level driving mechanism is connected with load 11, belt 9 is a first order drivign belt, and belt 14 is a second level drivign belt, and retarder is a deceleration arrangements.
The above-mentioned electric motor drive composite set that is easy to start, between retarder and first order belt gear, set up chain drive, described chain drive is made up of two sprocket wheels 3, its teeth number of sprocket is identical, wherein, a sprocket wheel connects the output shaft of retarder 2, and another sprocket wheel and big belt pulley 5 are fixed on the axle 13 jointly, is connected by chain 4 between the sprocket wheel.
The utility model is owing to set up belt gear, can be when startup or load rapid fluctuation or overload, utilize the characteristics of skidding between belt pulley and the belt, receive and start excess load or impact load, guarantee the motor smooth starting or make institute's bringing onto load normal rotation still, the overcurrent that motor produces when having avoided overload or burn phenomenon, the impact load back motor that disappears still can continue to run well.In addition, motor can be selected less rated power for use, thereby has reduced inrush current.Because the energy loss that line loss causes has also been saved in the minimizing of inrush current greatly.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Mark is as follows among the figure: motor 1, retarder 2, sprocket wheel 3, chain 4, big belt pulley 5, small belt pulley 6, big belt pulley 7, small belt pulley 8, belt 9, load 11, output shaft 12, axle 13, belt 14.
Embodiment
Fig. 1 is a structural representation of the present utility model, shows among the figure, and motor 1 is connected successively with retarder 2, sprocket wheel 3, two-stage belt gear, load 11.Sprocket wheel 3 is two, and their diameter is 1: 1, is connected by chain 4 between the sprocket wheel.The two-stage belt gear is made up of two anisodiametric large and small belt pulleys respectively, is connected with 14 by drivign belt 9 between them.In the two-stage belt gear, the big belt pulley 5 and the sprocket wheel 3 of the first order is fixed on the axle 13 jointly, and small belt pulley 6 and partial big belt pulley 7 are coaxial, and partial small belt pulley 8 is connected with load 11.
Be a design example of the present utility model below.
Motor speed is 1450 rev/mins, is 50 rev/mins after retarder 2 slows down, and still is 50 rev/mins after sprocket driving.After two-stage belt transmission speed change, be 800 rev/mins, drive load by this rotating speed rotation.Load is an induced draught fan, and its air quantity is 15000-20000M
3/ H, adopting motor power (output) is 1.5 kilowatts, and if directly drive, power demand substantially exceeds 1.5 kilowatts.
