ALUMINUM WORM GEAR SPEED REDUCER

INSTRUCTION MANUAL

Read these instructions thoroughly before installing or operating the gearbox.

GENERAL INSTALLATION INSTRUCTIONS

• Leave the protective shaft sleeves in place for safe handling of the gearbox during installation.

• This speed reducer is tested and filled with synthetic oil prior to shipment (Refer to the Lubrication

and Maintenance section for more information.)

• Align all shafts accurately, since improper alignment can result in premature failure.

• For hollow-bore output gearboxes – Use anti-seize compound when inserting the load shaft into

the Hollow Output Shaft. It is preferable to size the load shaft with sufficient length to allow

complete insertion through the Hollow Output Shaft of the gearbox. This allows equal support of

the load shaft by both of the output shaft bearings, and permits the use of the output shaft set

screws to lock the two shafts together on both sides of the gearbox. At minimum, the load shaft

should be inserted at least half way into the hollow output shaft, and secured with the setscrews

on the insertion end of the gearbox.

• Mount the gearbox to a rigid foundation, and use the maximum possible bolt size. Periodically

inspect the mounting bolts. (Refer to the Lubrication and Maintenance section for allowable

mounting orientations.)

• Mount auxiliary drive components such as sprockets, gears and pulleys on the gearbox shafts as

close to the housing as possible in order to minimize the effects of side loading. Avoid force fits

that might damage bearings or gears.

• Check and record gear backlash at installation and again at regular intervals. This should be done

by measuring the degrees of rotary movement of the output shaft (rotating alternately clockwise

and counterclockwise) while holding the input shaft stationary. The gearbox should be replaced

when the backlash exceeds four times the measurement taken at installation.

• Initial operating temperatures may be higher than normal during the break-in period of the gear

set.For maximum life, DO NOT ALLOW THE SPEED REDUCER TO OPERATE CONTINUOUSLY

ABOVE 225°F at the gear case. In the event of overheating, check for overloads or high ambient

temperatures. Keep shafts and vent plugs clean to prevent foreign particles from entering seals or

gear housing.

Preparing the Area

Clean the work area until it is free of debris and dust before disassembling the Reducer.

Contaminates can adhere to oil coating the parts and may damage the mechanism. Have a clean

container ready to place the parts during the disassembly process.

Tools Required

• 6mm Allen Wrench

• Torque Wrench

-Worm Gear Speed Reducers are Not To Be Considered a Fail Safe Or Self-Locking Devices. If These

Features Are Required, A Properly Sized Independent Holding Device Should Be Utilized.

-Depending Upon Gear Geometry and Operating Conditions, Worm Gear Speed Reducers May Or

May Not Back Drive. Special Consideration Should Be Given To High Inertia Loads Connected

To The Reducer Output Shaft.

-Reducers Driven By Brake Motors Must Be Sized To Accommodate Motor Driving and Brake and

Inertia Loads To Prevent The Braking Torque Or Inertia Loads From Exceeding The Motor Rating.

2. Lubrication and Maintenance

2.1 Lubrication

This speed reducer is shipped with oil and it is not necessary to fill it before use.

2.2 Oil Changes

The Speed Reducer is shipped to you filled with synthetic lubricant which should be changed every

6,000 hours of operation or every 2 years, which ever comes first.

It is very important to use the proper lubricant type. It is also very important to keep the oil free

from oxidation and contamination by water or debris.

1. Remove the oil Drain Plug (#6) to completely drain out the oil.

2. Replace the Drain Plug (#6) and remove the Steel Plug (#7). Refill with 10.14 oz. of recom-

mended gear oil.

3. Install the Steel Plug (#7) and torque to 195 in. lbs.

Note: If you fill the speed reducer with a synthetic lubricant, please use the original steel plug (see

fig.1).If you fill the speed reducer with a mineral lubricant, please use the supplied plastic air vent

for air bleeding (see fig.2).

Installation

1.1 Motor and Speed Reducer

RV series speed reducers are shipped with oil so they do not need to be filled before use.

1.2 Motor Wiring

To Power Supply

Connection of the electric motor to the power supply should be made by a qualified electrician. The

current rating of the motor will be identified on the motor plate, and the correct sizing of the wire to

meet electrical regulations is essential.

1.3 Mounting the Electric Motor to the Speed Reducer

1. Apply anti-seize compound to the Motor Shaft

2. Line up the electric motor key with the Input Hollow Shaft Key Slot（#17） and slip the Motor

Shaft into the Bore of Input Hollow Shaft(#18)

3. Install the four 3/8-16 UNC bolts and lock washers and tighten bolt (torque it to 225 in. lbs.)

evenly for a solid fit between Motor and “C” flange

1.4 Mounting The Speed Reducer

To mount the speed reducer feet to the equipment use 3/8" UNC bolts (Minimum ISO grade 8.8) and

torque them to 750 in-lbs.

It can either be free standing by foot mounting, or if required, mounted on a standard base-plate

with a foot mounted motor correctly aligned

a) Align the Speed Reducer

Note: It is important to insure when aligning the speed reducer on the base-plate that all machined

mounting points are supported over their full area.

During the final assembly insure the unit or base-plate are not distorted. This will cause strain on

the gear case resulting in the possible misalignment of the shafts and gearing.

b) Install safety guards in accordance with local regulations

c) Check the motor wiring diagram for the correct direction of rotation. This is important when a

load holding device has been added.
