Automotive Gearbox Bearing BB1-3913

Automotive Gearbox Bearing BB1-3913, the structural design and manufacturing process of this bearing are in accordance with strict standards to ensure its stability and reliability under shifting conditions, as it is subjected to frequent shifting under different driving conditions.

Product Description

Features:

1. Supporting rotating parts: 

   There are several rotating shafts in the gearbox, such as input shaft, output shaft, intermediate shaft, etc. Bearings are used to support these shafts so that they can rotate stably inside the gearbox. For example, the bearing on the input shaft supports the rotation of the input shaft and transfers the power from the engine to the inside of the gearbox.

2. Reducing friction and wear:

   The rolling elements inside the bearing (e.g., balls, rollers, etc.) have a low coefficient of rolling friction with the inner and outer rings, which effectively reduces the friction and wear between the shaft and the gearbox housing. This not only reduces energy loss and improves transmission efficiency of the gearbox, but also extends the service life of the gearbox.

3. Ensure rotary accuracy:

   High-precision bearings can ensure the rotary accuracy of the shaft, so that the gears can mesh correctly, avoiding problems such as increased gear wear and transmission noise due to shaft runout or offset. For example, in the automatic transmission of automobiles, the rotary accuracy of bearings is highly required to ensure the smoothness and reliability of gear shifting.

4. Transmission of power:

   In some special gearbox structures, such as planetary gearboxes, bearings can also play the role of transmitting power. The bearings connect the planetary gears with the sun wheel, toothed ring and other components to realize the transmission and distribution of power.
