Correct angle gearboxes (worm and planetary) are tough and built for 90° turns. Inline reducers (parallel shaft and planetary) are a perfect match for motors with high input speeds, or when gearmotor effectiveness is important. Contact our technical sales staff for help determining which gearbox option is most beneficial for you.
RIGHT ANGLE REDUCERS
WORM GEAR REDUCER
Groschopp’s worm equipment reducers were created with a hollow bore and allow for a corner change with optional dual output. The reducers come in 12 ratios which range 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 right 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 correct angle planetary gearboxes offer a robust solution. The right angle bevel gearbox will come 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 acceleration reducers. These gearboxes are created to deal with varying loads with little backlash. With frame 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 gears for noise-sensitive applications.
INLINE PLANETARY GEARBOX
inline-planetary-gearbox
Our inline planetary gearbox configurations supply the highest performance and best output torque of all our rate reducers. These gearboxes are created to deal with varying loads with little 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 gear cluster design provides an effective method for dissipating heat. Parallel shaft gearboxes possess the shortest amount of our inline equipment reducer options therefore they work very well in conditions with limited space. Our parallel shaft gear reducers provide an affordable drop-in replacement solution for most small parallel shaft gearmotors.
The typical precision PE-series inline planetary gearheads can be found in 40-155mm frame sizes and provide high torque, low backlash, high input speeds and a small package size with an excellent price/performance ratio.
The PE-series planetary gearbox is the perfect economy gearbox for all applications where substantially low backlash isn’t of vital importance.

There are three main elements in a planetary gearbox: the sun gear, the earth gears and the ring gear. The gears are mounted on the planet carrier that has teeth on the inside, which may be the ring gear.
Planetary Reducer & Gearmotor
Planetary Gearbox – DieQua Corporation
Planetary gearboxes are able to produce many different reduction ratios due to the different planet gears that revolve around sunlight gear. Planetary gearboxes are made of heavy duty metallic such as for example steel and are able to handle large shock loads well. However, different planetary gearboxes are designed for specific acceleration, load and torque capacities. The predominant use for planetary gearboxes is definitely in automobiles with automatic transmissions. Unlike manual transmitting, in which the operator is responsible 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 tranny contains two complete planetary gearsets positioned together into one component. Planetary gearboxes are also used in electrical screwdrivers, sprinklers and applications that want huge or multiple reductions from a compact mechanism. Planetary gearboxes are one of many variations of velocity reducers and it is essential that the right mechanism is used. Gearboxes could even be combined to produce the desired results and the most common kinds are helical gear reducers, worm gear reducers and inline gear reducers.
Planetary gearboxes gain their advantages through their design. Sunlight gear’s central position allows the earth gears to rotate in the same path and for the ring gear (the edge of the planet carrier) to turn the same way as the sun gear. In a few arrangements the sun gear can simultaneously change all the planets as they also engage the ring gear. The three components could be the insight, the output or held stationary, which results in lots of different reduction ratio options.
In lots of planetary gearboxes one component is held stationary with another element serving as the input and the other as output. The reduction ratios for planetary gearboxes are dependent upon the number of teeth in the gears and what parts are engaged. Generally, the strain ability and torque boosts with the amount of planets in the machine because the load can be distributed among the gears and there is low energy waste; planetary gearboxes are highly efficient, averaging between 96 and 98%. The look is complex, nevertheless, and difficult to gain access to for repairs or maintenance.
Axial or Inline gearboxes refer to such types as Helical, Shaft mounted, or planetary styles.
These gearboxes are extremely common options for most commercial applications due to 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 actually the only inline gearbox version with the choice of a hollow output shaft.
Planetary gearboxes are usually chosen for high tech, high torque, high speed applications requiring severe accuracy.
