The electric drum pulley is a new type of drive device that places the motor and the reducer together inside the drum body. It is mainly used in fixed and mobile belt conveyors, replacing the traditional electric motor, and the separate drive device with the reducer outside the driving drum.
The electric drum has many advantages such as compact structure, high transmission efficiency, low noise, long service life, stable operation, reliable operation, good sealing, small space occupation, convenient installation, etc., and is suitable for working in various harsh environmental conditions.
Electric drum pulley driven by fixed shaft gear
The most commonly used reducer device for electric drums at home and abroad is the fixed-axis gear transmission, and more than 95% of the gear transmission is the fixed-axis involute cylindrical gear transmission structure. The transmission has the advantages of simple structure, reliable performance, easy manufacture, convenient installation and maintenance, high efficiency and low noise. Two-stage deceleration is commonly used, and a few are three-stage deceleration.
Planetary geared drum motor
Compared with the fixed-axis gear transmission, this type of transmission has the advantages of small size, light weight, large bearing capacity and stable operation, but it is inconvenient to maintain. This type of structure is common in electric drums abroad.
Cycloid driven drum motor
This type of structure can be described as "Chinese characteristics". Except for Japan, other countries rarely use this transmission structure. The electric drum with the transmission structure of the cycloidal pinwheel can achieve a small linear speed and a large power.
As the power of belt conveyor and hoisting equipment, electric drum is widely used in mining, metallurgy, chemical industry, coal, building materials, electric power, food and transportation and other departments.
1. It can replace the widely used external drive device of motor-reducer type to form a belt conveyor, which can transport bulk materials such as coal, ore, sand, cement, flour, etc., and can also transport hemp bags, equipment and other items. .
2. The structure is simple and compact, and the occupied space is small.
3. Good sealing, suitable for high dust concentration, wet and muddy workplaces.
4, easy to use and maintain, safe and reliable operation, long life.
5. Low energy consumption and easy centralized control.
6. It can meet the needs of various backstops, braking, and rubber encapsulation.
Daily use and Maintainance
1. Before each start-up, routinely check the surrounding environment, tightening bolts, oil leakage, and the integrity of the cables, so as to create conditions for normal operation.
2. When the new drum is started, it should start by jogging, and gradually turn to normal. After 10 minutes of operation, check the vibration, noise and temperature rise of the running parts of the whole machine.
3. If there is oil leakage from the electric drum, pay attention to check two parts: one is the oil seal, whether it is worn or deformed, and the wear can make the oil seal lip position.
The spring coil is tightened, and the leakage can be solved for the oil seal with little wear. If it is invalid or deformed, the skeleton oil seal should be replaced in time; the second is that the air outlet channel cannot be blocked, and the silent dust, oil and debris should be removed as soon as possible to ensure that the channel is unobstructed.
4. The backstop used by the high-speed shaft of the external drum is generally cooled and lubricated by the cooling lubricating oil inside the cylinder through the internal channel to flow to the backstop for cooling and lubrication. A pressure filling oil cup is installed on the top of the backstop. When the backstop heats up quickly, an appropriate amount of oil should be pressed into the oil cup for supplementation. Not more than 150g. The backstop should be able to play a backstop function, otherwise the backstop will be deemed damaged.
5. Regular inspection of the oil level in the drum is an important part of daily maintenance. The specified oil level is one of the conditions to ensure the normal operation of the drum. The inspection method can be checked according to the method described in the instruction manual.
