Speed Reducers & Right Angle Drives


Precision Bu-ord Type Speed Reducers
The basic SI gearhead design is adapted to the double-ended Speed Reducers. The transition is accomplished by removing the motor and inserting the speed reducer input assembly using the same clamp to hold it securely and accurately in position. Either input or output end can be mounted in position since dimensions on both ends are identical. Models S9115A-T6123, S9115A-T6123A, and S9118A-T6128 single-end speed reducers use a compact reduction system whose input and output shafts are coaxially extended from the mounting end, enabling the design engineer to insert a large reduction at any location in the gear train with minimum space and backlash requirements. Consult the SDP/SI engineering staff for special applications.

Commercial & Precision Right Angle Speed Reducers
Precision quality worm gear speed reducers for high-torque applications, input speeds up to 6000 rpm are available in multiple ratios. Speed reducers are available in other styles where special shaft diameters or extensions are required. Small to miniature sized commercial quality worm gear speed reducers are also offered in multiple ratios.

Precision Synchro Clamps
Precision Synchro Mounting Clamps in a variety of styles, sizes and materials are available off-the-shelf. Commercial synchro mounting clamps are also offered, the difference being the material.

Many applications require a custom unit. Below is a list of some of the special applications gearheads and speed reducers that Sterling Instrument can produce from their inventory of existing designs.
Zero-Backlash Speed Reducers: For applications which require minimal lost motion throughout the gear train.
Splined Shaft Speed Reducers: For applications which require direct meshing with other component parts of the gear train.
Low-Backlash Speed Reducers: For applications which do not require zero backlash, but do require lower backlash than our standard units.
Tandem Speed Reducers: For applications which require reduction ratios higher than shown for our standard units.
Exact Ratio Speed Reducers:BuOrd Speed Reducers For applications requiring reduction ratios which are even integers.
Integral Slip Clutch Speed Reducers: For applications which require a built-in torque limiting device.
Heavy-Duty Speed Reducers: For applications which require two or three times the available output torque of standard speed reducers.
