1. The number and definition of assembly forms are different (1) ZSY: A total of 9 assembly forms (I~IX) through different orientation combinations of input shafts and output shafts on the box to cover various layouts such as left/right/upper/lower extension of the input shaft, left/right extension of the output shaft, etc. It can adapt to general industrial scenarios with limited space and changeable motor layout directions (2) DCY: only 4 assembly forms (I~IV) Type I: Left-out shaft (conventional type) Type II: Right-out shaft (conventional type) III Type: The left output shaft that can be installed with a backstop Type IV: The right output shaft that can be installed with a backstop Since the input and output shafts have been fixed at 90° vertical, the assembly form only distinguishes the left and right sides of the output shaft and whether it has a backstop position 2. Differences in backstop configuration DCY: Types III and IV have a backstop (brake) installation position reserved at the factory. They are specially designed for belt conveyors and other working conditions that require anti-reversal, and are standard configuration options Z Read More

1. Stop the machine immediately and cut off the power supply. Once the reducer is found to be overloaded (such as abnormal noise, severe vibration, excessive temperature rise, etc.), it must be stopped immediately and the power supply cut off. Continuous operation under high temperature or overload conditions is strictly prohibited to prevent more serious damage such as gluing of the worm gear or burning of the motor windings. 2. Check and eliminate the overload source. In the shutdown state, check in detail whether there is a fault on the load side, such as whether the equipment is stuck, whether the material is blocked, etc. Only after the direct cause of the overload is confirmed and eliminated can restarting be considered. 3. Check the lubricating oil status. Overloading is often accompanied by severe heating. It is necessary to check whether the lubricating oil level of the reducer is sufficient and whether the oil quality has deteriorated. If the oil becomes thinned, emulsified or contains a large amount of impurities due to high temperature, it is necessary to replenish or replace the lubricating oil that meets the specifications in time to restore good lubrication status. 4. Check the wear of mechanical components. Overloading can easily cause damage to internal transmission components. The worm gear should be inspected mainly Read More

1. Abnormal auditory and olfactory signals, piercing screams and friction sounds: Under high-speed and heavy-load conditions, if the tooth surface lubrication fails, causing a sudden rise in local temperature, and the metal surface is fused and then torn apart, severe 'piercing screams' or 'scorching sounds' will be produced, accompanied by strong metal friction noises. Odor generation: When severe gluing or burns occur, obvious odors can often be smelled, such as the smell of oil or burning metal. 2. Abnormal temperature and vibration. The shell temperature rises sharply: Excessive temperature rise is an important signal of gear damage. If the surface temperature of the reducer housing continues to rise or is locally hot (for example, a seriously high state exceeding 60°C), it indicates that the internal friction power has increased sharply, and a high degree of vigilance is required. Increased vibration: Along with abnormal noise, the device usually experiences significant body vibration. This kind of vibration is often caused by metal adhesion and severe friction on the tooth surface. 3. The condition of the lubricating oil deteriorates and the oil temperature suddenly rises: during actual operation Read More

1. Electrical parameters match current range and transformer: The current range of the protection device must match the rated current of the motor. For example, the rated current of a 22kW/380V motor is about 42A, and a protector with a 50A range should be selected. If a current transformer (CT) is used, ensure that the secondary output of the transformer matches the input of the protector (eg 150:5A). Working voltage: The voltage level of the control power supply needs to be confirmed. Common ones are 220V AC or 24V DC. 2. Load conditions and action characteristics, starting type and time characteristic curve: It is necessary to select an appropriate trip curve according to the starting characteristics of the motor to ensure that the protector can avoid the starting current. Class 10 is recommended for light load start (<3 seconds, such as fans); Class 20 is recommended for standard start (3-10 seconds, such as conveyors); Class 30 is recommended for heavy load start (>10 seconds, such as crushers). Shock load Read More

1. Mechanical overload protection (safety shear pin) This protection method is achieved by setting safety shear pins of specific specifications in the transmission system. When excessive resistance is encountered during operations such as mud scraping, causing the torque to exceed the set threshold, the shear pin will be sheared due to excessive force, thereby physically cutting off power transmission and protecting the equipment from damage. 2. Electrical overload protection (thermal relay) is mainly implemented by monitoring the operating current of the motor in real time. When the system is overloaded and the motor current exceeds its rated value, the thermal relay will determine it to be overloaded and trigger an action to stop the motor, thereby achieving the purpose of overload protection. In addition, in some more advanced overload protection reducer designs, friction discs, springs or magnetic couplings are also used to achieve overload release; or a displacement sensor, current detection and touch switch are combined to achieve automatic and rapid release when overloaded and output an alarm signal synchronously to improve the equipment's reliability.
