PHINIA Interview Questions and Answers

Selecting a gearbox involves understanding the application requirements and asking customers about key parameters.

• Understand the torque and speed requirements of the application

• Ask about the input and output shaft orientation

• Inquire about the available space for installation

• Consider the environmental conditions the gearbox will operate in

• Discuss the desired efficiency and noise level

Converting other make gearboxes to Nord gearboxes involves assessing compatibility, providing technical support, and offering incentives.

• Assess the compatibility of the existing gearbox with Nord gearboxes

• Provide technical support and guidance on the conversion process

• Offer incentives such as discounts or trade-in options to encourage the switch

• Ensure proper installation and testing of the new Nord gearbox

Gearbox selection on site involves comparing different gearmotors based on specifications, performance, and compatibility.

• Consider the required torque and speed for the application

• Check the mounting dimensions and shaft sizes to ensure compatibility

• Compare efficiency ratings and service factors for long-term reliability

• Evaluate the gear ratio and gear type based on the application's requirements

• Look for additional features such as overload protection or corrosion resistance

GD&T is used to specify the manufacturing process for components, ensuring proper fit and function.

• GD&T allows for clear communication of design requirements to manufacturers

• Manufacturing processes such as CNC machining, injection molding, and 3D printing can be specified using GD&T

• Examples include using position tolerances to control the location of holes or using flatness tolerances to ensure a surface is within a certain range of flatness

Power is calculated by multiplying torque and angular velocity, while torque is calculated by multiplying force and distance from the axis of rotation.

• Power = Torque x Angular Velocity

• Torque = Force x Distance from axis of rotation

• Example: Power = 100 Nm x 10 rad/s = 1000 W

• Example: Torque = 50 N x 2 m = 100 Nm
