Automatic gearbox internal bearing
The internal bearing is an important component of an automatic transmission (AT). It ensures smooth rotation of the transmission shafts, maintaining their alignment and reducing friction.
Functions of the automatic transmission internal bearing:
* Supports axial and radial load on transmission shafts
* Provides smooth rotation and positioning of shafts
* Reduces friction and wear between moving parts
* Increases gearbox life
Automatic transmission internal bearing design:
Internal automatic transmission bearings are usually tapered or needle bearings, which consist of:
* Inner ring: Mounted on the shaft and rotates with it.
* Outer ring: Installed in the gearbox housing and remains stationary.
* Rolling elements: Balls or rollers that are located between the inner and outer rings and provide rolling.
Types of automatic transmission internal bearings:
* Tapered bearings: Used to carry combined axial and radial loads.
* Needle Bearings: Used to carry radial loads in confined spaces.
Replacing the internal bearing of an automatic transmission:
Replacing an automatic transmission’s inner bearing is a complex task that should be performed by a qualified mechanic. The process usually includes:
1. Removing the gearbox from the car
2. Disassembling the gearbox and removing the faulty bearing
3. Cleaning and inspection of the seating surface
4. Installing a new bearing on the shaft
5. Assembling the gearbox and installing it on the car
Symptoms of a faulty automatic transmission internal bearing:
* Noise or clatter coming from the gearbox
* Vibration when shifting gears
* Slipping or slow response when shifting gears
* Transmission fault indicator on the dashboard
Regular maintenance and checking the transmission oil level can help prevent premature internal bearing failure. If you experience any of the above symptoms, it is recommended that you contact a qualified mechanic for diagnosis and repair as soon as possible.
