Planetary Gearboxes

In all the gear transmissions described so far, the gears are assembled on waves that are placed in a fixed gear. There are other gears in which one or more wheels are assembled on waves whose position changes during the operation of the gear, i.e. in addition to the rotational motion of the gear the shaft axis makes another rotational motion whose center of rotation is the axis of rotation of a central wheel in the gear. These gearboxes are planetary gearboxes.

In a planetary gear, a moving gear is called a “sun”, around the “sun” revolve at least 3 satellites, the satellites revolve inside a ring called a “planetary gear”. In the planetary gear, the planetary wheels are supported by a “plant carrier” (holder) to which the exit shaft is attached.
It is possible to make a planetary gearboxbetween the input axis and the output axis.

And

Planetary gearboxes have large transmission ratios in small gearbox dimensions. And
Planetary gears also use the propulsion systems required for variable transmission ratios. They make it possible to achieve different exit speeds at the same speed as entering the relay.

Technical data:

• The gearboxbody is made of shock-absorbing gray cast iron. The lower part is an oil tank and the gears are placed inside of it.
• Gears are made of nickel-chrome 15CrNi6 chrome-plated and tempered for 60 HRc surface hardness.
• Gears are sharpened with great precision at AGMA 11, ISO 6 level, ensuring long and quiet operation of the gearboxes.
• Hinges with large diameters for a high level of accuracy and better uniform difficulty.
• Wave edges are sharpened at k6 endurance for diameters up to 50 mm. Wave ends for diameters above 50 mm are sharpened at m6 endurance. Defects according to DIN6885 / 1.
• Bearings All hinges are supported by conical and ball bearings with standard freedom.
• The bearings are capable of carrying radial and axial loads in combination.
• Lubrication and lubrication system for all gearboxes including standard breather.
• The efficiency of the relay, as a result of advanced design and precise processing, efficiencies is extremely high and they reach up to 97% depending on the speed of rotation and the transmission ratio. Proper efficiency will be achieved after 10 hours of work at full load.
• Starting overload, all gears are designed to withstand a starting torque of 200% for 15 seconds, 150% for 60 seconds, and overdrive of 125% appearing once a day for 1 hour.

Complementary Products:

• Assemble the brake to an internal return to prevent rotation of the gearboxes in the opposite direction under the external load.
• The spring-loaded safety brake assembly is electromagnetically released.
• Wave protrusions in special dimensions, central drills according to DIN 332.
