DodgeRight Angle Worm Gear Reducer, 15:1 Ratio, 2.00 in Centre Distance, 56C Quill Input, 1 in Right Hand Output

Product Description

What this part is

A Dodge Tigear-2 right-angle worm gear speed reducer in the 2.00 in centre-distance frame, 15:1 nominal ratio, with a NEMA 56C quill input taking a 5/8 in motor shaft and a 1 in solid output shaft on the right-hand side. The worm set turns the drive through 90°, reduces speed and multiplies torque, the workhorse arrangement on conveyors, feeders, augers, mixers and packaging drives.

Decoding the order code

Tigear-2 numbers read as centre distance, input style, ratio, output shaft, motor frame. 20: 2.00 in centre distance, the gear case size and mounting footprint. Q: quill input, where the motor shaft enters a hollow quill in the reducer with no separate coupling. 15: 15:1 nominal reduction. R: solid output shaft on the right-hand side viewed from the input. 56: NEMA 56C motor flange, 5/8 in motor shaft.

What these specs mean in practice

Quill input is not the same as a C-face coupled input. The motor shaft becomes the worm input, so shaft diameter and length matter as much as the flange bolt pattern. There is no coupling to buy and none to wear out.

Centre distance, not ratio, sets the torque class. The 2.00 in frame is the small end of the Tigear-2 range; 2.3, 2.6 and 3.0 in frames are stronger and share no housing dimensions.

15:1 is a mid-range worm ratio and is not a self-locking arrangement.

R is the output hand. The L build is a mirror image.

Published specifications

Type: right-angle worm gear speed reducer, Dodge Tigear-2. Nominal ratio: 15:1. Centre distance: 2.00 in. Input: NEMA 56C quill, 5/8 in motor shaft. Output: 1 in solid shaft, right hand. Shaft orientation: right angle (90°). Housing: cast iron. Lubrication: factory filled and sealed. UPC: 782475748433. Origin: United States.

Quantity and configuration

One reducer. No motor is included; gearbox only. New old stock.

Mounting data

The motor shaft diameter and usable length set whether a motor seats in the quill. The unit is factory filled and sealed for a specified mounting position, and the correct oil level differs between mounting positions.

Interchange guidance

20Q15L56 is the opposite-hand output build. Other 20-series ratios share the housing and mounting but change output speed. A-code builds are C-face coupled rather than quill and do not interchange with a Q-code unit. Dodge Tigear-2 now ships under Regal Rexnord with unchanged numbering.
