What are the functions of gearbox?
The purpose of a gearbox is to increase or reduce speed. As a result, torque output will be the inverse of the speed function. If the enclosed drive is a speed reducer (speed output is less than speed input), the torque output will increase; if the drive increases speed, the torque output will decrease.
What are the factors to be considered in design of gearbox?
With this information, gearbox manufacturers can better assist you in selecting the correct gearbox for your intended application.
- Your choice: standard, modified standard, or complete custom.
- Main specs.
- Operation (duty cycle)
- Temperature range.
- Grease/oil.
- Environment.
- Input needs.
- Output needs.
What are the basic factors affect the gear selection?
In our experience, at a simplified level, there are three factors that are most important when selecting a gear material. They are strength, durability, and cost, which includes both the cost of the material and the cost of manufacturing.
What criteria is required when designing a gearbox based on input speed?
Requirements for Gear Design
- Overall gear ratio and number of different reductions and their gear ratios if multi-speed and the ratio tolerance.
- Size and envelope requirements.
- Weight restrictions.
- Input and output interfaces and dimensions.
How do I choose the right gearbox?
How to Select a Gearbox
- Speed and horsepower of the input.
- Desired output speed or desired output torque (will determine ratio)
- Characteristics of use; hours per day, nature of shock or vibration in the system.
- Degree of overhung load.
- Unit configuration, shaft input or hollow bore input, shaft output or hollow bore output.
What are the requirements of speed gearbox?
Basics of Gearbox Selection
- Service Factor. Before sizing an application, the customer should determine the service factor.
- Ambient Temperature and Environment.
- Shock Load or Type of Load.
- Output Style or Mechanism.
- Output Shaft or Hollow Bore Size.
- Housing Styles.
What is the duty cycle of a gearbox?
A duty cycle is the condensation of transmission usage over a lifetime to specific operating torques and speeds for a set duration.
