Conveyor electric drum basic classification

Currently the classification of electric drum There are four basic ways. That is based on the motor cooling method, using gear transmission structure type, electric drum basic

characteristics of the work environment and the motor is placed outside this drum are several ways to classify the electric drum.

One, in different ways according to the spiral conveyor motor cooling electric drum can be divided into three categories
Air-cooled electric drum
This is characterized by electric drum motor without oil cooling by conduction, radiation, convection and wind, can be divided into two kinds of forced air cooling and natural

cooling.
Oil-cooled electric drum
This electric drum also called indirect gravity conveyor oil-cooled electric drum. Drum motor has a cooling fluid, since the spinning roll body, scraper plate on the cylinder continuously poured

into the oil motor and the gear on the motor and gear away the heat generated during the operation, the heat transfer

The walls of the drum body, accelerate the motor cooling, and gears produce lubrication. Oil-cooled electric drum key is allowed to enter the interior of the motor oil.
Oil-filled electric drum
Oil-filled electric drum, also called direct oil-cooled electric drum, this type of electric drum allows flow into the interior of the motor directly with the motor rotor and

stator windings contact them work the body heat generated by the drum rotates continuously transmitted to the inner wall of the drum. This knot

The cooling structure is better, but the quality of the lubricant and the motor is relatively high requirements.

Second, the structure is divided by gear transmission electric drum type
Many domestic and foreign production reducer type, but can be used in the mass production of electric drum no more than three types.
Fixed axis gear drive electric drum
The most common domestic electric drum unit is fixed shaft gear reducer drive, and gear drive more than 95% fixed axis involute cylindrical gear transmission structure. These

transmissions orange simple structure, reliable performance, easy to manufacture, easy installation and maintenance, but also has high efficiency, low noise

Advantages. Top two deceleration, a few three deceleration.
OK amount of electric drum gear
The drive shaft geared form and relatively fixed, with small size, light weight, carrying capacity, smooth operation, etc., but the maintenance is not convenient, electric drum

abroad this common structure type.
Cycloid drive electric drum
This structure type described as "Chinese characteristics", except Japan, other countries rarely use this transmission structure, with cycloid structure of this drive small

electric drum can achieve great speed and power.

Third, according to the application environment to electric drum sub-sub
Electric drum of ordinary common application environment, corrosion, and explosive three kinds of occasions. If the subdivision still be hot, humid tropics, and some special

occasions, but these occasions the small number of electric drum, usually only as a non-standard electric drum production.

Currently there are: TDY75 type oil-cooled electric drum, DY1, JYD type mobile electric drum, YZ-type cycloid electric drum, exterior electric drum, TJ-type oil-immersed

electric drum.
