The 7.5KW motor and the hard-toothed KA107-70.1 gear reducer are matched. From a power perspective, KA107 The motor that can be matched by the reducer is relatively wide. Some data show that it can match a motor of 3 - 45kW, and some mentions that it can match a motor of 0.18 - 200kW, 7.5kW Within its matching power range. In addition, the reducer model is clearly marked with a 7.5KW motor, indicating that it is designed to be 7.5KW. Motor matching, including the gear strength of the reducer, bearing capacity, etc., are designed to withstand the torque and power output of the 7.5KW motor. However, in practical applications, other factors need to be considered, such as load characteristics, working environment, speed requirements, etc. If the load is an impact load or the working environment is harsh, further verification of Selection may be required and Read More

The oil level of the BLD4-11-7.5KW cycloid pin wheel reducer should usually be kept in the centerline of the oil viewing window. A reducer with oil windows horizontally placed, when the machine is stationary, the oil level reaches 2/3 of the oil mirror can also be considered normal. This is because the cycloid reducer generally uses oil pool lubrication. The appropriate oil level can ensure that the transmission components such as gears are fully lubricated, and can also avoid excessive heat generated during operation due to excessive oil level, increased risk of oil leakage, or damage to components due to poor lubrication caused by too low oil level. If the reducer does not have an oil window, refuel when placed horizontally, remove the upper observation cover and insert it vertically into the bottom of the box with a dipstick. The oil level height is generally 55mm−65mm. However, reducers produced by different manufacturers may vary. It is recommended to refer to the equipment's instruction manual to determine the exact oil level range. Read More

BLD5-35-18.5KW When the lubricant oil of the cycloid reducer is insufficient, the following may occur: abnormal temperature rise: During normal operation, the oil temperature of the reducer is generally maintained at 60℃-80℃. Insufficient lubricant will reduce the heat dissipation area and reduce the heat dissipation efficiency, and the oil temperature may rise to 90℃ or even higher. Long-term high temperature will accelerate the aging and deformation of the seal, resulting in oil leakage, which will make the lubricant oil even less and form a vicious cycle. Increased noise and vibration: lack of protection from lubricating oil, the friction between gears, bearings and other components increases, and the friction sound will be more obvious. At the same time, abnormal vibration may occur, affecting the smooth operation of the reducer. Intensified wear: insufficient lubricating oil cannot form a good oil film on the surface of the component. The contact surfaces of key components such as gears and bearings directly rub against each other, and the friction coefficient increases. For example, the friction coefficient between gears may increase from normal 0.05-0.1 to 0.2 or even higher. Read More

To check whether the soft tooth surface JZQ850-20.49-5 The reducer heat sink is installed firmly, you can refer to the following method: Visual inspection: Check the fixing parts: Carefully observe whether the fixing bolts, nuts or snaps of the heat sink are complete and whether there are any loose, missing or damaged conditions. If the bolt is found to be loose, tighten it in time; if there is any missing or damaged, a new fixing piece needs to be replaced. Check the appearance of the heat sink: Check whether the heat sink has deformation, cracks or damage. If these problems exist, it may affect the fit between the heat sink and the reducer body, and thus affect the heat dissipation effect. The heat sink needs to be corrected or replaced in time. Observe the installation position: Confirm whether the installation position of the heat sink is correct, whether it is closely fitted with the reducer body, and whether there is any misalignment or excessive gap. If so, re-adjustment and installation are required. Manual inspection: Shake the heat sink: When the reducer is shut down and the power is off, gently shake the heat sink to feel whether it has obvious shaking. Read More

Improper installation of the heat sink may cause the following faults of the JZQ750-31.5-1 The reducer has the following faults: Overheating and poor heat dissipation: The installation position of the heat sink is incorrect. If it is not installed near the heating part of the reducer, or if it is installed too tight or loose, it will affect heat conduction, which will prevent the heat generated inside the reducer from being dispersed into the surrounding environment in time, causing the oil temperature to rise, and thus causing the overall temperature of the reducer to rise. Long-term overheating will accelerate the aging and deterioration of the lubricant, reduce its lubricating performance, and affect the normal operation of the reducer. Local overheating: The heat sink is not installed uniformly, which will lead to uneven heat dissipation on the surface of the reducer and local overheating. This may cause some parts of the reducer to be deformed and damaged due to excessive temperatures, such as deformation of the seal, resulting in oil leakage, and wear of components such as gears and bearings. Increased noise and vibration are not firmly installed to produce additional noise, which may also cause friction between the heat sink and the reducer housing, further increasing Read More

Here are some application cases about ZDY280 - 6.3 - II gear reducer: Metallurgical industry: In steel rolling production lines, ZDY280 - 6.3 - II The gear reducer is used to drive the rolls, converting the high-speed rotation of the motor into the low-speed and high-torque rotation of the rolls, allowing the steel to be accurately rolled between the rolls to the desired thickness and shape. In a continuous casting machine, the reducer powers the crystallizer vibrating device and the pulling machine to ensure that the casting blank can be pulled out stably during solidification and has good surface quality. Mining industry: in jaw crusher, ZDY280 - 6.3 - II The gear reducer transmits the power of the motor to the movable jaw of the crushing chamber. Through the reduction and torque increase of the reducer, the movable jaw can squeeze and crush the ore at a suitable speed and force. In the ball mill, the reducer drives the cylinder to rotate, so that the inner cylinder is Read More
