Correct angle gearboxes (worm and planetary) are rugged and built for 90° turns. Inline reducers (parallel shaft and planetary) are an ideal match for motors with high insight speeds, or when gearmotor efficiency is important. Contact our technical sales staff for help identifying which gearbox alternative is best for you.
RIGHT ANGLE REDUCERS
WORM GEAR REDUCER
Groschopp’s worm equipment reducers are designed with a hollow bore and invite for a corner change with optional dual result. The reducers come in 12 ratios ranging from 5:1 to 100:1, with non-back-drivable ratios 30:1 and higher. Our right angle gearboxes are designed with five mounting options providing versatility when incorporating the reducer into item.
RIGHT ANGLE BEVEL GEARBOX
bevel-right-angle-gearbox
The right angle bevel gearbox combines the features of our right angle worm and planetary inline reducers. With a good and efficient right angle configuration, our correct angle planetary gearboxes offer a robust solution. The proper angle bevel gearbox comes in 18 ratios ranging from 5:1 to 1000:1, in fact 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 speed reducers. These gearboxes are designed to handle varying loads with little backlash. With body sizes 52cm, 62cm, and 81cm, 12 ratios ranging from 5:1 to 308:1, we have a solution to fit your needs. Our 52 frame size can be available with plastic-type material gears for noise-sensitive applications.
INLINE PLANETARY GEARBOX
inline-planetary-gearbox
Our inline planetary gearbox configurations provide the highest efficiency and best result torque of all our speed reducers. These gearboxes are made to manage varying loads with little backlash. Planetary gear reducers operate more quietly than parallel shaft reducers. With 18 ratio options ranging from 5:1 to 1000:1, we have a solution to fit your needs.
PARALLEL SHAFT GEARBOX
parallel-shaft-gearbox
Parallel shaft gearboxes will be the top choice for continuous duty applications. Their equipment cluster design provides a highly effective method for dissipating warmth. Parallel shaft gearboxes possess the shortest amount of our inline gear reducer options therefore they work well in conditions with limited space. Our parallel shaft gear reducers provide an affordable drop-in replacement solution for most small parallel shaft gearmotors.

There are three main parts 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 may be the ring gear.
Planetary Reducer & Gearmotor
Planetary Gearbox – DieQua Corporation
Planetary gearboxes can produce many different reduction ratios due to the different world gears that revolve around the sun gear. Planetary gearboxes are made of heavy duty metallic such as steel and are able to handle large shock loads well. However, different planetary gearboxes are designed for specific speed, load and torque capacities. The predominant use for planetary gearboxes can be in motor vehicles with automatic transmissions. Unlike manual tranny, in which the operator is responsible for switching gears, automobiles that have automatic transmissions make use of clutches, brake bands and planetary gearboxes to change the inputs and outputs, therefore adjusting the speeds appropriately.
An automatic tranny contains two complete planetary gearsets placed together into one element. Planetary gearboxes are also found in electric screwdrivers, sprinklers and applications that want huge or multiple reductions from a compact mechanism. Planetary gearboxes are one of many variations of quickness reducers and it is essential that the right mechanism is used. Gearboxes may even be combined to produce the desired results and the most common kinds are helical equipment reducers, worm gear reducers and inline gear reducers.
Planetary gearboxes gain their advantages through their design. The sun gear’s central placement allows the earth gears to rotate in the same direction and for the ring gear (the advantage of the planet carrier) to carefully turn the same way as the sun gear. In a few arrangements sunlight gear can simultaneously turn all the planets as they also engage the ring gear. Any of the three components could be the input, the output or kept stationary, which results in lots of different reduction ratio possibilities.
In many planetary gearboxes one element is held stationary with another element serving as the input and the other as output. The decrease ratios for planetary gearboxes are influenced by the number of the teeth in the gears and what elements are involved. Generally, the load ability and torque boosts with the number of planets in the system because the load is usually distributed among the gears and there can be low energy waste materials; planetary gearboxes are extremely efficient, averaging between 96 and 98%. The look is complex, however, and difficult to access for repairs or maintenance.
Axial or Inline gearboxes refer to this kind of types as Helical, Shaft mounted, or planetary styles.
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 within applications requiring high permissible radial force, stepped ratios and low backlash.
Shaft-mounted or otherwise known as Parallel shaft gearboxes offer an inline option with a versatile and space conserving foot print. This is actually 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.
