Reducer Manual

INSTALLATION

WARNING: Improper installation of the gear reducer may cause injury to personnel, gear reducer failure, or damage to driven equipment. Load conditions must be within the published catalog ratings with the recommended A.G.M.A. service factors properly applied.

SAFETY

WARNING: Rotating equipment is potentially dangerous and should be properly guarded. The user is responsible for checking all applicable safety codes in his area and providing suitable guards.

A. General

The reducer should be mounted on a flat surface on the machine or foundation, securely bolted down and accurately aligned. Shims under the mounting base should be used when required to provide a level mounting surface.

B. Solid Shaft Mounting

The output shaft can be connected to the load by flexible coupling, sprocket and chain, sheave and V belt, or pinion. Check to insure proper alignment and tension of all components. If sprocket, sheave, orpinion is used, mountascloseto gear housing as possible to minimize bearing load and shaft deflection. Overhung load must be checked to make certain it does not exceed published capacity.  When couplings, sheaves, sprockets, or pinions are mounted, it is important that extreme care be used. It is quite easy to damage internal parts by heavy blows used in trying to drive one of these parts on the shaft. It is recommended that a bore be selected to give a light driving fit. If a press fit is required, it is suggested that the external element be heated to assure an easy assembly. Heating beyond 250 degrees F. (1 21 C.) is not recommended, as heat conducted along the shaft, may damage the shaft seal.

C. Hollow Shaft Mounting

The torque arm of the Shaft mounted worm gear reducer must not be mounted too rigidly. If the torque arm is held down without any flexibility, shaft eccentricity, which is usually present, can overload the bearings of the gear reducer. The flexible grommet provided with all torque arms must be retained, or some other suitable means provided to allow the torque arm to be mounted with some flexibility. The torque arm should be mounted in tension (based on direction of rotation).

D. Long Term Storage (6 months and up)

Units should be stored in a protected area (preferably indoors). If stored outdoors, they should be covered to be protected from rain and snow. Wherever stored, units should be filled completely with oil. The input shaft should be rotated so that the output shaft makes at least one revolution per month. The input and output shafts should be covered with grease to protect from corrosion and rust. At start up time, completely drain storage oil and fill to proper oil level with the correct lubricant.

LUBRICATION

All Electra worm reducers and gearmotors are shipped with oil.
