Planetary Carrier Assembly: The planetary carrier assembly plays a vital role in distributing torque and power through the gears, enabling seamless gear shifting.
Hexagon Socket Cheese Head Screw M12X1.25: These specially designed screws secure the components in place, ensuring stability and preventing any loosening during operation.
Planetary Carrier (Front): This component houses the planetary gears, which are essential for transmitting power from the input to the output shaft.
Torque Transmission Sleeve: The torque transmission sleeve efficiently transfers torque from the input shaft to the output shaft, promoting smooth power delivery.
Output Shaft: Responsible for transferring power to the wheels, the output shaft is a critical element in the sub box assembly.
Sun Wheel Spacer (Front): Positioned between the sun wheel and the assembly, this spacer provides proper spacing and alignment for smooth gear engagement.
Sun Wheel and Bushing Assembly: Comprising the sun wheel and accompanying bushing, this assembly enables effective power transmission and rotation.
Spline Transition Bushing: This bushing facilitates the seamless transition of power between different spline components, ensuring efficient gear engagement.
Sun Wheel: The sun wheel is a central gear in the assembly, which receives input power and transfers it to the planetary gears.
Sun Wheel Spacer (Rear): Similar to the front spacer, this rear spacer maintains proper spacing and alignment for optimal gear performance.
Rolling Bearing 63/22 GB/T276: Another high-quality rolling bearing that supports smooth rotations and reduces friction, contributing to the overall efficiency.
Planetary Wheel Shaft: The planetary wheel shaft connects the planetary gears and enables their rotation, effectively distributing power within the assembly.
Roller Spacer: This spacer ensures proper spacing and alignment between the cylindrical rollers, promoting smooth operation and load distribution.
Cylindrical Roller 11X18Ⅲb GB4661: The cylindrical rollers are key components in the assembly, responsible for transmitting power and supporting load.
Planetary Wheel: The planetary wheels work in conjunction with the sun wheel and other components, aiding in torque distribution and gear engagement.
Planetary Wheel Spacer: This spacer ensures proper spacing and alignment of the planetary wheels, enhancing the overall functionality of the assembly.
Elastic Retaining Ring for Hole: With its elastic properties, this retaining ring secures components within the assembly, preventing any unintended displacement.
Hole with Flattened Steel Wire Retaining Ring: This specially designed hole features a flattened steel wire retaining ring to securely hold components in place during operation.
Rolling Bearing 61820 GB/T276: A high-quality rolling bearing used within the assembly to facilitate smooth rotations and reduce friction.
Inner Gear Ring: The inner gear ring is responsible for meshing with the planetary wheels, enabling effective power transmission and gear selection.
Gear Ring Holder: This component securely holds the inner gear ring in place, ensuring proper alignment and engagement with other gears.
