They are proven to depths of 3000m subsea in applications such as retrievable chokes, pig launchers, subsea risers and TDUs.
Selecting the Right Gearbox
When selecting a gearbox there are a number of factors which influence the final size of the selected unit. You can view this information in the Bevel Gearbox Selection Guide. The selection procedure is a 12 step process that uses the following application information to select a bevel gearbox.
- Bevel Gearbox Input Speed (rpm)
- Bevel Gearbox Output Speed (rpm)
- Bevel Gearbox configuration
- Required Output Torque (Nm)
- Operating Hours per day
- Input Power Source Bevel Gearbox application
- Number of starts per hour
- Transmission methods
- Duty cycle per hour (% running time)
- Operating ambient temperature
