Description
Technical field
The utility model belongs to fixing vertical feed mixer technical field, relates to the driving mechanism of fixing vertical feed mixer, relates in particular to the motor drive system of driving mechanism.
Background technology
The driving mechanism conduct of fixing vertical feed mixer is typically mechanical, electric to be the equipment of one, undertaking the vital task that the rotation of fixing vertical feed mixer tool holder system grinds fodder, it is the main core component of all kinds of fixing vertical feed mixers, wherein motor is its " heart " part, i.e. power source parts.
At present, the motor drive system that mainly adopts of the driving mechanism of fixing vertical feed mixer can be divided into following two classes:
1, phase asynchronous ac motor dragging system
This is phase I of Electric Traction development of the driving mechanism of fixing vertical feed mixer, and common phase asynchronous ac motor satisfies the performance and the requirement of the driving mechanism of fixing vertical feed mixer by the measures such as deceleration of shaft coupling, drive link, reductor.Because squirrel-cage asynchronous motor is difficult to satisfy the driving mechanism starting of fixing vertical feed mixer and the requirement of speed adjusting performance, therefore many employing wound rotor asynchronous motors drag.Can limit starting current and improve starting torque after the crosstalk resistance of coiling type asynchronous motor rotor loop, and speed governing within the specific limits.Advantages such as this system has simple in structure, and is sturdy and durable, easy to maintenance, cheap, and Installation and Debugging are convenient.Shortcoming is: the start-up period electric energy loss is bigger, and when being used for the driving mechanism of the requirement frequent starting or the different speed of service and varying level fixing vertical feed mixer, this problem is more outstanding.Owing to carry out speed governing by excision rotor loop resistance, so the speed adjusting performance of system is bad, speed adjustable range is little and be step speed regulation.Phase asynchronous ac motor dragging system complexity, transmission mechanism is long, floor space is big, efficient is low etc.
2, the phase asynchronous ac motor dragging system of frequency control
Because the speed adjusting performance of wound rotor asynchronous motor is not ideal enough, so people just begin to adopt this driving style.The phase asynchronous ac motor speed control performance of frequency control is better, and it is more reliable to work.The phase asynchronous ac motor dragging system of frequency control, be to pass through to be equipped with variable-frequency power sources, satisfy the performance and the requirement of the driving mechanism of fixing vertical feed mixer through the measures such as deceleration of shaft coupling, drive link, reductor by the phase asynchronous ac motor of frequency control.By variable-frequency power sources, change supply frequency, thereby change the rotating speed of the phase asynchronous ac motor of frequency control, reach the speed governing purpose of crane walking.Shortcoming is: the cost height still needs to satisfy the performance and the requirement of the driving mechanism of fixing vertical feed mixer through the measures such as deceleration of shaft coupling, drive link, reductor.Efficient is low, and the equipment complexity, transmission mechanism is long, floor space is big etc.
The motor drive system of above-mentioned two class fixing vertical feed mixers exists all that some we do not wish the shortcoming and the problem that exist.Such as, the existence of reductor, the existence of drive link, the existence of shaft coupling, the existence of the protective cover of long driving-chain has not only increased totle drilling cost, the mechanism's complexity that also causes whole system, the driving-chain of whole system is long, directly causes transmission efficiency greatly to reduce, and exists problems difficult in maintenance or the like.The reductor volume is big, power shaft becomes 90 ° with output shaft, needs bigger mounting seat.Because the reductor input connects the threephase asynchronous of a high-speed cruising, its bearing noise is big during operation, and its operation noise is generally about 60-70db.There is mechanical wear inevitably in gear drive, and along with the increase of running time, wearing and tearing make between the moving component gap become big, cause noise aggravation, transmission efficiency to descend.In mechanical driving device, though the reductor transmission system has the advantage that reduces rotating speed and increase moment of torsion, its decrease in efficiency, loss of energy, operation noise are big etc., and shortcoming can't overcome.Generally speaking, transmission efficiency has the electric energy of 20-30% to be wasted with the thermal losses form between 60-88% approximately.For the frictional heat that produces in the wearing and tearing that reduce reductor and the transmission slip process, the use of lubricating oil is essential, periodic replacement lubricating oil has not only increased the regular maintenance expense, and the oil gas that produces in the running and greasy dirt also can cause direct pollution to environment.
