How to choose the appropriate ZL350-40-I reducer industry standard based on actual needs

When choosing the appropriate ZL350-40-I reducer industry standard, the following aspects should be considered:

Clearly define job requirements

Transmission ratio: The transmission ratio is determined based on the rotational speeds of the input and output shafts, with the formula i=n1/n2, where n1 is the input speed and n2 is the output speed. The nominal transmission ratio of ZL350-40-I reducer is 40, and it needs to be confirmed whether this transmission ratio meets the speed requirements in actual operation.

Power and torque: Calculate the required power and torque to be transmitted. Determine the input power and output torque that the gearbox should have based on the load characteristics of the working machine. The power can be calculated using the formula P=T × n/9549, where P is the power (kW), T is the torque (N ⋅ m), and n is the speed (r/min). Meanwhile, considering the complexity of the operating conditions, it is also necessary to multiply by the operating condition coefficient K. The value of the operating condition coefficient is determined based on factors such as the load nature of the working machine, daily working time, and number of starts. For example, when the load is stable, working for 3-10 hours per day, and starting up ≤ 5 times per hour, the operating condition coefficient K can be taken as 1; If there is impact or frequent starting of the load, the K value should increase accordingly.

Speed: Confirm whether the input speed range of the reducer can meet the speed requirements of the prime mover, and whether the output speed can meet the operating speed requirements of the working machine. Generally speaking, the input speed of the gearbox should not exceed its rated speed, otherwise it may cause problems such as increased bearing wear and rising oil temperature.

Consider the working environment

Environmental temperature: The working environment temperature will affect the heat dissipation of the gearbox and the performance of the lubricating oil. The working environment temperature suitable for ZL350-40-I reducer is generally between ℃ and ℃. If the ambient temperature is below ℃, the lubricating oil should be preheated to above ℃ before starting; If the ambient temperature is higher than ℃, cooling measures such as installing cooling fans or cooling coils should be taken.

Installation method: Choose the appropriate installation method based on the actual installation space and equipment layout. ZL350-40-I reducer has multiple installation methods, such as horizontal, vertical, etc. Different installation methods may affect the lubrication and sealing of the gearbox. For example, a vertically installed gearbox may require special lubrication measures to ensure that the lubricating oil can reach all lubrication parts.

Protection level: If there are pollutants such as dust and water vapor in the working environment, it is necessary to choose a gearbox with the corresponding protection level to prevent pollutants from entering the interior of the gearbox and affecting its normal operation. Generally speaking, gearboxes used outdoors or in dusty environments require higher protection levels, such as IP54 or IP65.
