DX-DO Series — Dual-Output and Vertical-Output Worm Gear Reducer<\/h2>\n

The DX-DO Series addresses two niche layout requirements that the standard A-type and S-type models do not cover. The DX variant<\/strong> extends the output shaft through both sides of the housing, creating a dual horizontal drive that powers two parallel loads — twin conveyor rollers, split chain drives, or symmetrical gate arms — from a single motor and worm gear reducer<\/strong>. The DO variant<\/strong> rotates the output axis 90° so the shaft points vertically upward, which suits valve actuators, vertical screw lifts, and roof-vent openers. Both models integrate an IEC motor flange for direct motor attachment and are available in thirteen frame sizes (WP40–WP250) with ratios from 5:1 to 60:1.<\/p>\n

\"DX-DO<\/div>\n

Where Dual and Vertical Outputs Add Value<\/h2>\n

Split Conveyor Drives (DX)<\/h3>\n

Packaging lines running twin-belt or twin-chain conveyors in parallel often need both sides to rotate at exactly the same speed. A DX reducer solves this by driving both chains from the same worm wheel output shaft, guaranteeing synchronous speed without electronic coordination. This is a common arrangement on Bosch Rexroth and Hytrol pallet-transfer systems where tracking accuracy between lanes matters. The solid dual-end output shaft accepts sprockets, pulleys, or couplings on both sides, and the foot-mounted housing bolts to a standard cross-member between the two conveyor frames.<\/p>\n

Vertical Actuators and Screw Jacks (DO)<\/h3>\n

When the driven shaft must point upward — to raise a sluice gate, tilt a solar panel array, or lift a mezzanine platform — the DO configuration places the output shaft vertically while the motor remains horizontal. At ratios of 30:1 and above, the inherent self-locking worm gearbox<\/strong> property holds the load in position without a separate brake, which simplifies the control circuit and reduces hardware cost. Frame sizes WP80–WP175 cover the torque range most screw-jack and linear-actuator applications require.<\/p>\n

Specifications at a Glance<\/h2>\n

Torque and power data below apply at 1,500 r\/min input. The DX and DO share the same gear pair and housing as every other single-stage model on the speed reducer gearbox<\/a> platform, so efficiency and bearing ratings are identical.

\"DX-DO<\/p>\n

DX dual-output and DO vertical-output shaft configurations<\/p>\n<\/div>\n

Engineering and Construction<\/h2>\n

The DX-DO housing is a one-piece grey cast-iron casting with foot pads machined on two perpendicular planes. For the DX variant, the output bore is bored through the full housing width and fitted with sealed bearings at both ends, ensuring the dual output shaft runs concentrically even under asymmetric loading. The DO variant uses the same bore but installs a bearing cap on the lower face, directing the shaft upward. Both variants accept the standard B5\/B14 IEC motor flange on the input side with h6-tolerance bore and parallel keyway. The worm shaft is case-hardened alloy steel ground to a mirror finish; the worm wheel is centrifugally cast tin-bronze (ZCuSn10Pb1) hobbed to full-depth involute profile. Oil seals on every shaft penetration are double-lipped NBR with a dust-exclusion outer lip to handle industrial environments.<\/p>\n

Oil and Maintenance<\/h2>\n

Fill with ISO VG 220–320 EP gear oil for temperatures up to 40 °C. For the DO vertical-output arrangement, check that the oil level fully submerges the lower worm-wheel tooth zone — the fill quantity is higher than horizontal configurations and is specified per frame in the installation manual. First oil change at 100 hours, then every 2,500 hours or annually. Inspect shaft seals for weeping during each oil change; the DO variant places the lower seal under a small head of oil, so any wear shows up as drips beneath the housing.<\/p>\n

Frequently Asked Questions<\/h2>\n
\n1. What is the difference between DX and DO? +<\/span><\/summary>\n
DX<\/strong> has dual horizontal output shafts extending from both sides of the housing — useful when two parallel loads must be driven from one motor. DO<\/strong> has a single output shaft pointing vertically upward, ideal for vertical pump or valve-actuator drives.<\/div>\n<\/details>\n
\n2. Can I use only one side of the DX dual output? +<\/span><\/summary>\n
Yes. Cap the unused shaft end with the supplied dust cover and key blank. The bearing arrangement supports single-side loading without modification.<\/div>\n<\/details>\n
\n3. Is the DO orientation suitable for outdoor installations? +<\/span><\/summary>\n
The standard IP55-equivalent sealing handles rain and dust. For fully exposed or washdown environments, add stainless-steel shaft seals and a breather filter. Contact us for the upgraded seal package.<\/div>\n<\/details>\n
\n4. What motor mounting position does the DX-DO use? +<\/span><\/summary>\n
Both variants use the same IEC motor flange with the input shaft entering horizontally. The motor sits perpendicular to the output axis, forming the characteristic right angle worm gearbox<\/strong> geometry.<\/div>\n<\/details>\n
\n5. Are replacement worm wheels available for the DX-DO? +<\/span><\/summary>\n
Yes. The worm wheel is identical across all single-stage WP models of the same frame size. Order by frame number (e.g. WP120 worm wheel) and it fits the DA, DS, DKA, DKS, DX, and DO variants interchangeably.<\/div>\n<\/details>\n
