Which of the devices listed are used to rigidly mount reduction gear bearings in their housings?

Question 1 of 27070

Which of the devices listed are used to rigidly mount reduction gear bearings in their housings?

🔍 Key Concepts

• Difference between rigid mounting and allowing limited movement or self-alignment of a bearing • How keys/keyways and dowels/locking screws are commonly used in machinery to prevent rotation or shifting • What a spherical housing does for a bearing (alignment vs rigidity)

💭 Think About

• Which option(s) are mainly meant to keep a part from rotating or shifting in its seat once aligned, providing a fixed, repeatable position? • Which option describes a design that actually allows some misalignment or movement, rather than holding the bearing completely rigid? • Think about typical bearing housings in reduction gears: how do mechanics ensure the bearing goes back into exactly the same position during reassembly?

✅ Before You Answer

• Identify which device(s) are used specifically for positive location (no play, no rotation) of components in heavy machinery • Ask yourself which choices are primarily for self-alignment rather than rigid mounting • Consider which devices are commonly used as precision locators during assembly and maintenance of reduction gear bearings
