Solar gearbox
The solar gearbox is the latest gearbox offered to the industry. The reason for its name is the way the gears are placed and its movement. This gearbox is used to transmit the maximum torque in the smallest possible dimensions, which is called torque density. The solar gearbox consists of a sun gear (central) which is surrounded by a planetary idler gear or pinion that is integrally placed on the rack or planetary carrier on its support axis, and the rack is also surrounded inside the inner gear or ring. There is a lot of driving stress on the teeth, so the load is balanced, so this design is more durable. The gear of the solar gearbox can be more resistant than the standard gear and transmit high torques.
Technical specifications of the solar gearbox
The members of the solar assembly (ring, solar, rack) in automatic transmissions are fixed or driven by clutches and bands. In general, five different modes can be examined in the set. Of course, it should be known that the set cannot have five modes in the gearbox. In gearboxes, they use two or three sets to create a suitable gear ratio.
Technical specifications of the solar gearbox
In the solar gear gearbox motor, the gears slide on top of each other and rotate around the middle axis of the (solar) gear. A solar gear gearbox consists of a solar gear and a ring, a number of star gears and a star gear rack ring. . In the solar gear system, which has three main components, one of these three components must be fixed so that the other two components can transmit the power as a driver and mover.

Types of solar gearbox based on connection type
Solar gearboxes are available as hollow input shaft, single spline, flanged (MC), base (UC), female shaft (FS).
Step motor and servo motor solar gearbox
Step motor and servo motor are high precision devices. Therefore, the gearbox used must have very little slack. Step motor solar gearbox, which is also known as small solar gearbox, has this feature. The unique design of this gearbox has made it able to be installed on servo motor and stepper motor alone without the use of connecting tools. This gearbox is used in CNC machines, rocket launchers, etc.
Important points in checking modes
Pay attention to the number of solar gears, the number of ring gears and the number of rack gears.
The driver means the member to which the input torque is applied and transfers the force to the moving member.
Gear ratio = the number of moving gears divided by the number of driving gears
Different device modes:
Rule of thumb: no member is involved.
The direct rule is that it is enough to integrate two members together.
Rear gear: In this mode, the rack is fixed and we will have two modes, the optimal mode is that the sun is driven and the ring is mobile. Because in this case we will have an increase in torque. In the second case, we will increase the gear ratio, which is not suitable for reverse gear.
The heavy gear rule has two modes.
(moving shelf - driving ring - fixed solar)
(moving frame - fixed ring - solar drive) the greatest increase in torque
Overdrive Law:
(drive rack - fixed ring - moving sun) the greatest increase in gear ratio
(Moving rack - movable ring - fixed solar)
Investigating power transmission in the solar gearbox assembly
To check the modes, one must have a good perception to visualize the direction of the components. It will be easier to understand if you have a replica of this collection. For each gear, the direction of the sun, ring, rack and pinions should be considered.
The direction of rotation of ring and pinion due to the internal gear of ring always agree with each other and the direction of rotation of sun and pinion are opposite, like two external gears.
Investigating one of the modes (heavy gear law) solar drive - moving rack - fixed ring
As you can see, the power (distance) is transferred to the rack from the sun that rotates clockwise, because the ring is fixed, so the pinions rotate in the opposite direction. The rotation direction of the shelf (output) will be in the right direction because there is no escape.

The advantages of solar gear motor compared to helical and worm gear
Because these gearboxes are the new generation of gearboxes in the world, they have a superior metallurgical structure, and due to the structure of these gearboxes, the gear engagement level has increased up to two times, which reduces the pressure on the gears and increases the service life of these gearboxes. becomes
The small volume of these gearboxes is one of their advantages due to the way the gears are placed, which makes it easier to work with these gearboxes.
Due to the internal structure of these products, their repairs are very easy and fast, which reduces the concern of the consumer in the field of repairs and maintenance.
Very high efficiency up to 98%
Long service life due to balanced distribution of load between floors
Very little slack due to the high precision in gear machining
