Right angle gearboxes (worm and planetary) are tough and built for 90° turns. Inline reducers (parallel shaft and planetary) are an ideal match for motors with high insight speeds, or when gearmotor performance is important. Get in touch with our technical sales staff for help determining which gearbox answer is most beneficial for you.
RIGHT ANGLE REDUCERS

Groschopp's worm equipment reducers were created with a hollow bore and allow for a corner turn with optional dual result. The reducers can be found in 12 ratios ranging from 5:1 to 100:1, with non-back-drivable ratios 30:1 and higher. Our correct angle gearboxes are designed with five mounting choices providing versatility when incorporating the reducer into product.
RIGHT ANGLE BEVEL GEARBOX
bevel-right-angle-gearbox
The proper angle bevel gearbox combines the top features of our correct angle worm and planetary inline reducers. With a good and efficient right angle configuration, our right angle planetary gearboxes offer a robust solution. The proper angle bevel gearbox comes in 18 ratios ranging from 5:1 to 1000:1, and it is back-drivable at all ratios.
INLINE REDUCERS
I-SERIES PLANETARY GEARBOX
i-series-planetary-gearbox
Our I-Series little planetary gearbox configurations supply the smallest footprint and quietest operation of our quickness reducers. These gearboxes are designed to handle varying loads with small backlash. With framework sizes 52cm, 62cm, and 81cm, 12 ratios ranging from 5:1 to 308:1, we've a solution to fit your needs. Our 52 frame size is also available with plastic-type gears for noise-delicate applications.
INLINE PLANETARY GEARBOX
inline-planetary-gearbox
Our inline planetary gearbox configurations provide the highest effectiveness and best output torque of all our acceleration reducers. These gearboxes are designed to handle varying loads with small backlash. Planetary gear reducers operate more quietly than parallel shaft reducers. With 18 ratio choices ranging from 5:1 to 1000:1, we have a solution to suit your needs.
PARALLEL SHAFT GEARBOX
parallel-shaft-gearbox
Parallel shaft gearboxes are the best choice for continuous duty applications. Their equipment cluster design provides a highly effective method for dissipating heat. Parallel shaft gearboxes possess the shortest length of our inline equipment reducer options therefore they work well in environments with limited space. Our parallel shaft equipment reducers provide an affordable drop-in substitute solution for most small parallel shaft gearmotors.

There are three main elements in a planetary gearbox: sunlight gear, the earth gears and the ring gear. The gears are attached to the planet carrier which has teeth inside, which is the ring gear.
Planetary Reducer & Gearmotor
Planetary Gearbox – DieQua Corporation
Planetary gearboxes can produce many different reduction ratios because of the different world gears that revolve around sunlight gear. Planetary gearboxes are made of heavy duty steel such as steel and are in a position to handle large shock loads well. However, different planetary gearboxes are made for specific swiftness, load and torque capacities. The predominant use for planetary gearboxes can be in automobiles with automatic transmissions. Unlike manual transmitting, where the operator is accountable for switching gears, automobiles that have automatic transmissions use clutches, brake bands and planetary gearboxes to improve the inputs and outputs, thereby adjusting the speeds accordingly.
An automatic transmitting contains two complete planetary gearsets placed together into one element. Planetary gearboxes are also used in electrical screwdrivers, sprinklers and applications that require huge or multiple reductions from a concise system. Planetary gearboxes are one of many variations of swiftness reducers and it is essential that the right mechanism is used. Gearboxes may even be combined to produce the desired outcomes and the most typical kinds are helical gear reducers, worm gear reducers and inline gear reducers.
Planetary gearboxes gain their advantages through their design. Sunlight gear's central placement allows the planet gears to rotate in the same direction and for the band gear (the edge of the planet carrier) to carefully turn the same way as sunlight gear. In a few arrangements sunlight gear can simultaneously convert all the planets because they also engage the band gear. The three components could be the input, the output or kept stationary, which results in lots of different reduction ratio possibilities.
In lots of planetary gearboxes one element is held stationary with another element serving as the input and the other as output. The reduction ratios for planetary gearboxes are influenced by the number of tooth in the gears and what parts are engaged. Generally, the strain ability and torque increases with the number of planets in the machine because the load is distributed among the gears and there is usually low energy waste materials; planetary gearboxes are extremely efficient, averaging between 96 and 98%. The look is complex, nevertheless, and difficult to access for repairs or maintenance.
Axial or Inline gearboxes refer to this kind of types as Helical, Shaft mounted, or planetary designs.
These gearboxes are extremely common choices for most commercial applications because of their robust nature, high permissible radial forces, closely stepped ratios and low backlash.
Helical gearboxes can typically be found in applications requiring high permissible radial force, stepped ratios and low backlash.
Shaft-mounted or otherwise referred to as Parallel shaft gearboxes offer an inline option with a versatile and space conserving foot print. This is the only inline gearbox version with the choice of a hollow output shaft.
Planetary gearboxes are usually chosen for hi-tech, high torque, high speed applications requiring intense accuracy.
