Speed ​​reducers are widely used equipment in industrial enterprises. Oil leaks not only cause economic losses, but severe leaks can also lead to insufficient or no oil supply, accelerating wear on gear meshing surfaces, and potentially causing welding or peeling, resulting in equipment accidents. Furthermore, oil leaks cause significant environmental pollution and corrosion to foundations, disrupting civilized production and wasting valuable recyclable lubricating oil. Below, we will explain the causes of speed reducer oil leaks, hoping to provide some helpful information. In a closed speed reducer, the friction between meshing gears generates heat. According to Boyle's Law, as operating time increases, the temperature inside the speed reducer housing gradually rises. Since the volume inside the housing remains constant, the pressure increases accordingly. Lubricating oil splashes onto the inner walls of the speed reducer housing. Due to the high permeability of oil, under the pressure inside the housing, oil will leak from any point where the seal is not tight. The speed reducer structure is designed…

With the development of the social economy and increasingly fierce market competition, the current gear reducer market is flooded with brands of varying quality. While many gear reducers emphasize their hardware advantages—such as gear processing technology and oil seal casting materials—to enhance their competitiveness, software configuration issues are sometimes unavoidable. Therefore, manufacturers must pay close attention to the reduction ratio when selecting a gear reducer. Let's understand the proper matching of the gear reducer's reduction ratio and the motor power it can handle. Speaking of gear reducers, the reduction ratio is one of their attributes. How is the reduction ratio determined? The machine's operating speed is determined, and then the gear reducer's reduction ratio is calculated based on this speed. The gear reducer's reduction ratio = input shaft speed / output shaft speed = motor speed / required machine speed. Changing or modifying the reduction ratio after it's been determined is equivalent to rebuilding the entire machine, wasting production time and delaying customer delivery…

Planetary gear reducers are very popular in the market, and many companies choose them because of their high acceptance and excellent reputation among consumers. Planetary gear reducers are a primary type of reducer used in servo motors. What factors need to be considered when selecting one? Details are as follows: When choosing a planetary gear reducer, you need to determine the reduction ratio. If the standard reducer does not have the reduction ratio you need, please choose a close one or have a custom reducer made by our company. The minimum reduction ratio for a single stage of a planetary reducer is 3, and the maximum is generally no more than 10. Common reduction ratios are 3/4/5/6/8/10. The number of stages is generally no more than 3, but some custom reducers with large reduction ratios have 4 stages. Compared to other reducers, planetary reducers have high rigidity, high precision (single stage can achieve within 1 minute), high transmission efficiency (single stage in 97%-98%), high torque/volume ratio, and a lifetime…

Based on the operating characteristics of this bevel gear reducer, the material used for the gears must not only have sufficient strength, hardness, and wear resistance, but also excellent resistance to low-cycle fatigue and impact. Analysis of imported mining machinery shows that foreign mining machinery gears primarily use Ni-Cr and Ni-Cr-Mo low-carbon alloy steels, which offer good strength, toughness, and processability. Previously, most bevel gears in the loading mechanisms of domestically produced tunneling machines used 20CrMnTi and 30CrMnTi. While these two steels have high strength, they have poor toughness and are prone to tooth breakage. In particular, 30CrMnTi, after carburizing and quenching, has high core hardness, and the tooth surface and transition zone are almost entirely hardened, significantly reducing bending fatigue strength and impact toughness. The bevel gear reducer's gears are low-speed, heavy-load gears, with a gear pair transmitting a torque of 7660.93 Nm. To achieve maximum load capacity under impact and heavy-load conditions while minimizing volume…

The function and structural characteristics of inter-turn insulation in geared motors are as follows: Inter-turn insulation in geared motors isolates the potential difference between components within the same layer of the armature winding. The voltage it withstands is the inter-layer voltage, with a maximum voltage not exceeding 24 volts. Medium and small DC motors generally use armature coils wound with electromagnetic wire. The varnish film and glass fiber insulation layer on the conductor surface are sufficient to meet the requirements for inter-turn insulation. Mechanical damage should be avoided during coil forming and winding. Large DC motors, due to the large cross-sectional area of ​​the armature conductor, generally use bare copper wire winding. After forming, mica tape or thin film tape is wrapped around it to improve reliability. The inter-turn insulation thickness should be thin; otherwise, the utilization rate of the armature slots will decrease.

Today we'll introduce some tips for using speed reducers: 1. After 200-300 hours of continuous operation, the first oil change should be performed. The oil quality should be checked regularly during subsequent operation, and any oil contaminated with impurities or deteriorated must be replaced promptly. Generally, for speed reducers operating continuously for extended periods, the standard is to change the oil after 5000 hours of operation or annually. For speed reducers that have been out of service for a long time, the oil should be changed before restarting operation. The speed reducer should be filled with oil of the same brand as the original; it's best not to mix oils of different brands, but oils of the same brand but different viscosities can be mixed. 2. When changing the oil, wait until the speed reducer has cooled down to a point where there is no risk of combustion, but it should still be kept warm. This is because when the oil temperature completely cools, the viscosity increases, making draining difficult. However, it is important to note that the power supply to the transmission device must be disconnected to prevent accidental energization. 3. During operation, if the oil temperature rises above 80℃ or the oil sump…

With the widespread application of speed reducers in the machinery industry, our understanding of speed reducer basics needs to be strengthened. Only by understanding speed reducer basics can we better operate speed reducers. Based on everyone's knowledge of speed reducer basics, we have introduced the following methods/processes: First, pay attention to the construction of the speed reducer installation site. The installation site of the speed reducer requires a flat ground and good ventilation. The installation site has a significant impact on the future use of the speed reducer. Second, pay attention to the daily maintenance of the speed reducer. Don't just use it without maintenance; this is a major taboo in the use of speed reducers. No matter how good the equipment is, without maintenance, its lifespan will be reduced by at least one-third. Therefore, daily maintenance is particularly important. Daily maintenance of speed reducers includes: changing the lubricating oil, checking the installation foundation, seals, drive shaft, etc. for proper functioning, and cleaning important parts such as the housing. Gearbox cleaning and protection machines utilize the original oil supply and drainage system of the gearbox…

A steering gearbox, also called a commutator or steering unit, is a power transmission mechanism and a series of gearboxes widely used in industry. Steering gearboxes have now achieved standardization and diversification. Below, we'll discuss the oil change intervals and types of steering gearbox lubricants. Oil Change Interval: a. Initial use: Two weeks or 100-200 hours. This is the initial wear period, during which a small amount of metal wear particles may occur. Please clean the interior and replace the lubricating oil. b. Long-term use: Replace the lubricating oil every six months to one year or 1000-2000 hours. Lubricating Oil Type: Use China Petroleum All-Purpose Gear Oil (90-120 degrees Celsius). For low speed and light load conditions, it is recommended to use All-Purpose Gear Oil (90 degrees Celsius). For heavy load and high temperature conditions, it is recommended to use All-Purpose Gear Oil (120 degrees Celsius).

In simple terms, the function of an oil seal is to seal oil, preventing leakage of oil from the inside of the gearbox. Oil is an essential liquid in the gearbox transmission system, so the oil seal's role is to ensure no oil leakage. The most common types of oil seals are single-piece and assembled types. Both the output and input ends of the gearbox have oil seal devices. As the gearbox operates for longer periods, the oil temperature rises. The oil seal protects the gearbox bearings from oil leakage, thus maintaining the normal operation of the gearbox oil. Oil is a liquid substance and is volatile; the higher the temperature, the faster it evaporates. The quality and lifespan of the gearbox oil are directly related to the quality of the oil seal. Therefore, a high-quality oil seal can improve the gearbox's operating time and lifespan. Oil seals also help prevent resource waste (oil) and increased costs. When selecting a gearbox, the quality of the oil seal and its…

Judging the oil level while the reducer is running will result in a significant discrepancy with the actual oil level. It is recommended to measure the oil level and add the appropriate amount of worm gear reducer lubricating oil when the reducer is operating intermittently. Reducer manufacturers usually provide instructions on the recommended oil level for worm gear reducers, filling the oil level to 2/3 of the oil window. However, this is for a stopped state. Note: Do not add lubricating oil while the worm gear reducer is running. During operation, the internal components (gears or worm gear) rotate, causing the internal lubricating oil to move as well. Judging the oil level under these conditions might result in it being full, below 2/3 of the oil window, or even almost empty. For new reducers, the oil should be replaced after 300 hours of continuous operation, and then every 2500 hours thereafter. However, the oil quality should still be checked regularly during use. If the oil contains impurities…
