711-60-14210 GEAR
There are various types of bulldozer gears according to different transmission requirements. For example, in a gearbox, spur cylindrical gears, helical cylindrical gears, etc. are often used. For example, the gearbox of a tracked bulldozer uses a spatial three-axis sliding gear shift, which achieves multiple forward and reverse gears through the meshing of different gears. In the central transmission system, spiral bevel gears are often used, such as the high-strength spiral bevel gears commonly used in the central transmission gear pair of wetland bulldozers. In the final transmission device, spur cylindrical gears or planetary gears are generally used.
The application of gears
Final transmission device
The final transmission gear further reduces the speed and increases the torque of the power transmitted from the central transmission device, and then transmits it to the driving wheels to drive the bulldozer. The strength and wear resistance of its gears directly affect the walking performance and reliability of bulldozers.
Mining
In high dust and high impact environments, gears need to have wear resistance and sealing performance. For example, the gear 14X-13-11221 of the Komatsu bulldozer is designed specifically for mining conditions.
