- What are the advantages of hard tooth surface reducerHard tooth surface reducers are widely used in metallurgical industry, mining, lifting, logistics transportation, cement mortar, engineering construction, chemical industry, textile and clothing, textile printing and dyeing, pharmaceutical and chemical industries and other scientific and technological fields.The hard tooth surface reducer is a power transmission mechanism that uses the speed converter of the gear to reduce the number of revolutions of the motor to the desired number of revolutions and obtain a relatively large torque device.The hard tooth surface reducer refers to the reducer with the hardness of the internal gear of the reducer > 350HBS, and the large and small gears have been quenched or carburized.It is a relatively precise machine. The purpose of using it is to reduce the speed and increase the torque. It is suitable for the speed of the high-speed shaft not greater than 1500 rpm, the peripheral speed of the gear transmission is not greater than 20 m/s, and the working environment temperature is -40 ° C. -45°C environment.The gears of the hard tooth surface reducer are made of high-strength low-carbon alloy steel through carburizing and quenching. The tooth surface has high hardness.
- What is the difference between a planetary reducer and a worm gear reducer1. Different properties: The planetary reducer is a widely used industrial product, which can reduce the speed of the motor and increase the output torque at the same time.The worm gear reducer is a power transmission mechanism that uses the speed converter of the gear to reduce the number of revolutions of the motor (motor) to the desired number of revolutions and obtain a larger torque.2. Different uses: the planetary reducer can be used as a supporting component for lifting, excavation, transportation, construction and other industries.The worm gear reducer can be seen in the transmission system of various machinery, from ships, automobiles, locomotives, and heavy machinery used in construction.3. Different characteristics: the worm gear reducer has a compact mechanical structure, a light volume and shape, small size and high efficiency.The planetary gear reducer adopts a modular design, which can be changed and combined according to customer requirements.Precautions: 1. Hammering is strictly prohibited: when installing couplings, pulleys, sprockets, etc. on the output shaft of the planetary reducer, direct
- How to distinguish planetary reducer and cycloid reducer?Cycloidal pin gear reducer is a novel transmission device that applies the principle of planetary transmission and adopts cycloid pin-tooth meshing.The entire transmission device of the cycloid reducer can be divided into three parts: input part, deceleration part and output part.A double eccentric sleeve with misalignment degree is installed on the input shaft, and two roller bearings called rotating arms are installed on the eccentric sleeve to form an H mechanism. The raceway, and the cycloid wheel meshes with a set of circularly arranged pin teeth on the pin gear to form an internal meshing reduction mechanism with a tooth difference. (In order to reduce friction, in a reducer with a small speed ratio, pins with pin sleeves on the pins).When the input shaft rotates a circle with the eccentric sleeve, due to the characteristics of the tooth profile curve on the cycloid wheel and the limitation of the needle teeth on the pin gear, the movement of the cycloid wheel becomes a plane motion with both revolution and rotation. When the input shaft rotates one revolution forward, the eccentric sleeve also rotates one revolution, and the cycloid wheel rotates one revolution in the opposite direction.
- Advantages and disadvantages of worm gear reducer and gear reducerReducer transmission principle: gear transmission-mainly relying on the tooth profile of the driving gear to push the tooth profile of the driven gear to complete the transmission.Worm gear reducer - mainly relies on the sliding friction of the tooth surface when the active worm gear meshes, so that the worm gear tooth surface generates relative motion to complete the transmission.Defects of gear transmission: Gears, box processing equipment, gear processing and grinding technology, assembly technology and other requirements are more stringent, resulting in high manufacturing costs. Gear transmission has no overload protection and does not have self-locking performance. Additional brake devices are required , Relatively loud noise, small single-stage gear transmission ratio (generally no more than 1:7), etc.The gear meshing clearance is small and so on.Advantages of gear transmission: The reducer box can transmit the movement and power between any shafts in the space, that is, the shafts can be parallel, interspersed or interlaced; the rotation is stable, its transmission range is large, and it can be designed with multi-stage gear transmission, which has a wide range of applications, long service life and high efficiency. High (90%~99%), the cabinet is mainly made of cast iron, and the outer
- What should I do if the reducer does not turn on?The high-power reducer is a power transmission mechanism that uses the speed converter of the gear to reduce the number of revolutions of the motor to the desired number of revolutions and obtain a larger torque mechanism.After the high-power reducer is put into use, various failures are inevitable. Only by knowing more about the working principle and usage methods of the high-power reducer can the problem be solved when a failure occurs.Today, Dongchen Xiaobian made a detailed analysis on the problem that the high-power reducer does not turn after being connected to the power supply: 1. If the power supply fails and does not turn after being connected to the power supply, the most basic reason must be checked first-the power supply, the power supply is connected The power transmission of the equipment is an important equipment, so the power inspection should pay attention to: whether the switch is faulty, whether the fuse is blown, whether there is a short circuit between the wiring and the high-power reducer does not turn.2. Bearing failure If the above two reasons are detected and the high-power reducer is still unable to operate, then
- Use the reducer correctly to avoid unnecessary lossesThe reducer will be used in many industries, but for those who don't know about the reducer, we still don't know what problems the reducer will encounter in the application process.How do we deal with these problems? Today, Dongchen Xiaobian will introduce to you: First, the reducer should be used for low-speed applications, the speed does not exceed 1000 rpm, and the suitable range is 1000 to 3000 PPS (0.9 degrees).It can be operated through a reduction gear.The motor has high efficiency and low noise.Do not use the entire step state of the reducer, and the vibration is large in the entire step state.For loads with a large moment of inertia, a motor with a large frame size should be selected.When the motor is under high-speed or large inertia load, it generally does not start at the working speed, but gradually increases the frequency to increase the speed. One motor does not lose its step, and the second time can reduce noise and improve the positioning accuracy of the stop.For high precision, it should be solved by mechanical deceleration, increase the motor speed, or use high-resolution drive
- The reducer can use the above method to check the working performanceJudging from the sound: when the reducer is running, different sounds will appear, indicating that the reducer has different conditions. We can judge whether the reducer is good or bad by hearing, but if we need accurate judgment, we still need a sound detector specially used to check the reducer. INews August 24, 2022
