How to Select a Gearbox?
Industrial gearboxes are mechanical devices that are used for changing the speed or increasing the torque of motors. These gearboxes are attached to the motor shaft and they increase speed or torque by the gear ratio. Gearboxes are extensively used in the paper industry, cement industry, sugar industry and steel industry. There are a variety of industrial gearboxes that can be used in different types of applications.
If you are planning to buy an industrial gearbox, you must be aware of the intended use, load type and other important factors at the time of selection. As a leading e-marketplace for unused and genuine MRO spares such as industrial gearbox, ball bearings and ring gears, we help you understand the important factors:
Service factor: Defining the service factor is the start point of buying an industrial gearbox. For this, you need to be aware of concerns such as
- Non-uniform laid
- Type of input
- Hours of use per day
- Elevated ambient temperature.
- Any shock or vibration present in the application
Note: Determine a service factor rating to select the appropriate industrial gearbox. For instance, in most industrial applications, a service factor of 1.4 is adequate. This service factor signifies that the gearbox can handle 1.4 times the application requirement.
- Ambient temperature: In different industries, industrial gearboxes are exposed to different ambient temperatures. Higher ambient temperatures increase internal pressure. This means an industrial gearbox of a higher service factor rating is needed. Variations in temperatures can also affect the choice of seal materials and lubrication viscosities.
- Operating conditions: The environment the gearbox will function in is an important factor to take into account. Harsh operating conditions can increase wear-tear and exposure to moisture can cause corrosion or bacteria growth. It is for this reason that in the food industry, gearboxes with special coatings are used. Failing to take into these environmental factors can result in you selecting a gearbox that cannot support the application properly.
- Load distribution: When buying an industrial gearbox, consider the load they must support. A gearbox may misalign in case it is handling too much weight without support.
- Gear ratio: The gear ratio is defined using the number of gears and teeth in driver gear. The wider the driver gear, the more teeth the device will have. The optimal gear ratio is important to ensure the power transfer between the motor and load is optimized.
- Enclosure type: When selecting a gearbox, it is important to consider how it will be mounted. Some gearboxes have mounting feet while others have basic tapped holes on one or more sides to hang.
- Gearbox price: Gearbox price is an important factor when you are buying unused MRO spares. You can buy industrial gearboxes from mjvaluemart where you can browse through the catalogue of products and buy gearboxes at competitive prices.
