Right angle gearboxes (worm and planetary) are durable and built for 90° turns. Inline reducers (parallel shaft and planetary) are a perfect match for motors with high input speeds, or when gearmotor efficiency is important. Contact our technical sales staff for help identifying which gearbox option is best for you.
RIGHT ANGLE REDUCERS
WORM GEAR REDUCER
Groschopp’s worm gear reducers were created with a hollow bore and allow 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 correct angle gearboxes were created with five mounting choices providing flexibility when incorporating the reducer into item.
RIGHT ANGLE BEVEL GEARBOX
bevel-right-angle-gearbox
The proper angle bevel gearbox combines the top features of our right angle worm and planetary inline reducers. With a good and efficient correct angle configuration, our right angle planetary gearboxes provide a robust solution. The proper 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 small planetary gearbox configurations provide the smallest footprint and quietest operation of our quickness reducers. These gearboxes are designed to handle varying loads with small backlash. With frame sizes 52cm, 62cm, and 81cm, 12 ratios ranging from 5:1 to 308:1, we have a solution to suit 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 performance and best output torque of most our velocity reducers. These gearboxes are made to handle varying loads with little backlash. Planetary gear reducers operate more quietly than parallel shaft reducers. With 18 ratio choices which range 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 temperature. Parallel shaft gearboxes have the shortest length of our inline gear reducer options therefore they work very well in environments with limited space. Our parallel shaft equipment reducers provide an affordable drop-in alternative solution for most small parallel shaft gearmotors.

There are three main components in a planetary gearbox: sunlight gear, the planet gears and the ring gear. The gears are mounted on the planet carrier that has teeth on the inside, which is 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 constructed of heavy duty metallic such as steel and are in a position to handle large shock loads well. However, different planetary gearboxes are created for specific acceleration, load and torque capacities. The predominant use for planetary gearboxes is usually in motor vehicles with automated transmissions. Unlike manual transmission, where the operator is accountable 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 accordingly.
An automatic tranny contains two complete planetary gearsets placed together into one component. Planetary gearboxes are also used in electrical screwdrivers, sprinklers and applications that require huge or multiple reductions from a compact system. Planetary gearboxes are among the many variations of swiftness reducers and it is important that the right mechanism can be used. Gearboxes could even be combined to produce the desired results and the most common kinds are helical equipment reducers, worm equipment 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 advantage of the earth carrier) to carefully turn the same manner as the sun gear. In some arrangements the sun gear can simultaneously convert all the planets as they also engage the ring gear. Any of the three components could be the insight, the output or held stationary, which results in lots of different reduction ratio possibilities.
In many planetary gearboxes one element is held stationary with another component 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 involved. Generally, the strain ability and torque raises with the amount of planets in the system because the load is distributed among the gears and there can be low energy waste; planetary gearboxes are highly efficient, averaging between 96 and 98%. The look is complex, however, 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 very common options for most industrial 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 saving foot print. This is actually the only inline gearbox edition with the option of a hollow output shaft.
Planetary gearboxes are often chosen for high tech, high torque, high speed applications requiring severe accuracy.
