Product Details

Our business enterprise can independently layout and system forging dies in keeping with the drawings, and has many years of experience in forging planetary carriers. the burden of the cast planet provider product can attain 6kg-400kg, and the forging needs to be completed via heating, pre-forging, forming, trimming and other strategies. various materials consisting of 42crmo, 4140, 4130, 40cr, 20crmnmo, 18crnimo7-6, 410ss may be forged.

Planet Carrier

Planetary gear means that the rotation axis is not fixed, and it is installed on a rotatable bracket (blue) (the black part in Figure 1 is the housing, and the yellow part is the bearing). In addition to the planetary gears (green) rotating around their own rotating shafts (B-B) like fixed shaft gears, their rotating shafts also rotate around the axis (A-A) of other gears with the blue bracket (called planetary carrier). The rotation around its axis is called "rotation", and the rotation around the axis of other gears is called "revolution", just like the planets in the solar system, hence the name.

The planetary gear mechanism is divided into single planet row and double planet row according to the different groups of planetary gears installed on the planet carrier.

Compared with ordinary gear transmission, planetary gear transmission has many unique advantages. The most remarkable feature is that the power can be divided when transmitting power, and the input shaft and output shaft are on the same horizontal line. Therefore, planetary gear drive has been widely used in reducer, speed increaser and transmission device of various mechanical transmission systems. Especially because of its characteristics of "high load, large transmission ratio", it has been widely used in aircraft and vehicles (especially heavy vehicles).

The planetary gear also plays a great role in the torque transmission of the engine. Because the speed and torque characteristics of the engine are quite different from the road driving requirements, the above characteristics of the planetary gear can be used to convert the power of the engine to the driving wheel properly. The automatic transmission in the automobile also uses these characteristics of planetary gears to obtain different transmission ratios by changing the relative motion relationship of various components through clutches and brakes.

However, due to the complex structure and working condition of planetary gears, their vibration and noise problems are also quite prominent, which easily lead to such failure phenomena as gear tooth fatigue pitting, tooth root crack and even gear tooth or shaft fracture, thus affecting the operating accuracy, transmission efficiency and service life of equipment.

Customers in any industry the usage of forgings can request a quote for any amount of forgings, from one prototype at a time and small batches to high volume manufacturing. our extensions consist of gear slicing to finished gear size.
