What Are The Main Accessories in The Gearbox

Gear reducer accessories are very important parts in the gear reducer. We are not sure if we have paid attention to some of its important parts in our daily use of the gear 

reducer, and whether we are clear about the roles played by these important parts. In fact, there are many important parts in the gearbox, so it is recommended that we 

take a look at the role it plays together.

Introduction to the primary accessories of reducer accessories:

1. The box and cover are the supporting and containment components of the transmission parts in the reducer, with a complex structure. The box between them is subjected 

to pressure and requires outstanding rigidity, vibration reduction, and sealing. When producing individual small batches of box covers and boxes, gray cast iron materials (HTl

50 or HT200) are selected and cast into shape using a craftsmanship molding method; Alternatively, carbon structural steel (Q235A) can be selected and welded by manual arc 

welding.

2. The shaft, gear shaft, and gear are all important transmission parts in the reducer. The shaft and gear shaft are subjected to the combined action of bending short and twi-

sting short, requiring good comprehensive mechanical performance; The gear shaft and the tooth portion of the gear are subjected to significant contact and bending stresses, and should have outstanding wear resistance and high strength. When producing single pieces, medium carbon steel (45 steel) can be used to form by free forging or die for-

ging, or round steel bars made of medium carbon steel can be turned.

3. The rolling shaft in the reducer receives radial and axial compressive stress, requiring high strength and wear resistance. Rolling bearings are standard parts, and their inner 

and outer rings are made of corrugated bearing steel (GCrl5) for enlarged casting. Rolling balls are made of rolling bearing steel (GCrl5) for spiral oblique rolling, and the cage 

is made of high-quality carbon structural steel (08 steel) for stamping.

4. The primary function of bearing end caps is to prevent bearing movement and provide protection.

5. The bolts and nuts serve to fix the box cover and body, and the bolt rod is subjected to longitudinal (axial) tensile stress, bending stress, and transverse shear stress. The 

quality of the gearbox and every component that makes up it are important. As long as the quality of each component is good, the quality of the gearbox is good. If you want 

to purchase products with better quality, it is important to choose a reputable manufacturer.

In addition to the accessories mentioned above, there are other important accessories in the gearbox. For example, oil seals are used as seals inside bearings or gearboxes in gearboxes, which can prevent lubricating oil leakage and dust from entering, thus ensuring the normal operation of the gearbox. At the same time, the oil seal can also withs

tand certain pressure and temperature to protect the internal parts of the reducer from damage. In addition, lubricating oil is an indispensable accessory in the gearbox, which 

can lubricate the internal parts of the gearbox, reduce wear and friction, and extend the service life of the gearbox.

Therefore, when using a reducer, it is also very important to choose and replace the appropriate lubricating oil correctly. In short, every accessory in the gearbox plays an impor

tant role, and only when each component can play its best role can the quality and performance of the gearbox be guaranteed.
