Basic concepts and basic classification of electric conveying rollers
Clicks:2664 Date:7-5
The utility model relates to an electric conveying roller, which is a novel driving device for placing an electric motor and a reducer in the cylinder body. It is mainly used in stationary and mobile belt conveyors
A separate drive for a conventional motor and a reducer outside the drive drum.
The basic concept of an electric conveying roller
In recent years, according to some special occasions of belt conveyor, there has been a reduction device between the separation drive and the driven form of the electric roller
The outer motor is mounted outside the cylinder body.
Compared with the separated driving device, the electric drum has the advantages of compact structure, high transmission efficiency, low noise, long service life, stable operation, reliable operation and good sealing performance,
The utility model has the advantages of small space occupation, convenient installation, etc., and is suitable for working under various abominable environment conditions. It includes wet, muddy and dusty working environment.
Basic classification of electric conveying rollers
At present, there are four basic methods for classification of electric drum. That is to say, according to the cooling mode of motor, the drive structure type of retarder and the basic working environment characteristic of electric roller are adopted
And the motor is placed inside and outside the drum to classify the electric rollers.
According to the cooling mode of motor, different classification
Air cooled type electric conveying roller
This kind of electric roller is characterized by that the motor is not cooled by oil, and by convection of conduction, radiation and wind, it can be divided into two types, forced air cooling and natural air-cooled.
Oil cooled electric delivery roller
This kind of electric roller is also called indirect oil cooling type electric roller. There is a certain amount of cooling oil in the electric drum. As the cylinder rotates constantly, the oil scraping plate on the cylinder will hold the oil
Continuously pour into the motor and gear, take away the heat generated by the motor and the work of the gear, transfer heat to the cylinder wall, accelerate the cooling of the motor, and produce the gear
Raw lubrication. The key to the oil cooled electric roller is that the motor is not allowed to enter the oil.
Oil immersed type electric conveying roller
Oil immersed type electric roller is also called direct oil cooled electric drum, electric drum of this type allows the oil to enter the interior of the motor, and the motor rotor and stator winding
The heat generated by the work is transmitted continuously to the inner wall of the drum by the roller. The cooling effect of this structure is better, but for lubricating oil and motor
Relatively high quality requirements.
According to the reducer drive structure classification
There are many types of reducers produced at home and abroad, but there are no more than three types that can be produced on electric rollers at large.
An electric roller for shaft drive
At home and abroad, the most commonly used gear reducer is the fixed axis gear drive, and more than 95% of the gear drive is the fixed axis involute cylindrical gear transmission structure. such
The utility model has the advantages of simple structure, reliable performance, easy manufacture, convenient installation and maintenance, and high efficiency and low noise. Commonly used two speed reduction, a small number of three speed reduction.
An electric transmission roller for a gear drive
Compared with fixed shaft gear drive, this kind of transmission has the advantages of small size, light weight, large carrying capacity and stable operation, but it is inconvenient to maintain
This type of structure is common in rollers.
Electric conveying roller driven by cycloidal needle wheel
This type of structure can be described as "Chinese characteristic", except in Japan, other countries rarely use this kind of transmission structure, and the electric roller with the driving structure of cycloidal pin wheel can be realized
Very small wire speed and great power.
