HYTROL 4A RH Right Angle Gear Reducer C-Face

INTRODUCTION

This manual provides guidelines and procedures for installing, operating, and maintaining your conveyor. A complete parts list is provided with recommended spare parts highlighted in gray. Important safety information is also provided throughout the manual. For safety to personnel and for proper operation of your conveyor, it is recommended that you read and follow the instructions provided in this manual.

Receiving and Uncrating

  1. Check the number of items received against the bill of lading.
  2. Examine condition of equipment to determine if any damage occurred during shipment.
  3. Move all crates to area of installation.
  4. Remove crating and check for optional equipment that may be fastened to the conveyor. Make sure these parts (or any foreign pieces) are removed.

NOTE : If damage has occurred or freight is missing, contact your Hytrol Integration Partner.

How to Order Replacement Parts

Included in this manual are parts drawings with complete replacement parts lists. Minor fasteners, such as nuts and bolts, are not included.
When ordering replacement parts:

  1. Contact Dealer from whom conveyor was purchased or nearest HYTROL Integration Partner.
  2. Give Conveyor Model Number and Serial Number or HYTROL Factory Order Number.
  3. Give Part Number and complete description from Parts List.
  4. Give type of drive. Example—8” End Drive, 8” Center Drive, etc.
  5. If you are in a breakdown situation, tell us.

General Information

Most HYTROL conveyor drives are supplied with the HYTROL Speed Reducer. Models 4A and 5A Speed Reducers are used with V-Belt drives, whereas the 4AC and 5AC Reducers are supplied with the “C” Face Drive.

Determining Gear Ratio

To determine the ratio and/or the assembly date of a HYTROL Reducer, refer to the numbers stamped on the end of the output shaft.
Figure 4A shows the location of these numbers. AVAILABLE RATIOS ARE ALSO CHARTED IN THIS FIGURE.

Determining Right or Left Hand Reducer

To determine a right hand or left hand HYTROL Reducer, look into the output shaft with the input shaft on the high side. If the input is on the right side, it is a right hand reducer. If it is on the left, it is a left hand reducer. (See Figure 4B).

MAINTENANCE

The HYTROL Speed Reducer, if properly used, should require little maintenance except for scheduled lubrication. Instructions for changing oil and recommended lubricants are as follows.

Lubrication

Initial Oil Change–Drain the oil in a new Speed Reducer after approximately 500 hours of operation and refill with recommended oil from lubrication chart (Figure 5B).

Regular Oil Change–After initial change, in normal conditions, the oil should be changed every 2500 hours of operation, or every 6 months, whichever is first.
To Refill–Determine position of Reducer from Figure 5A and refill with amount of oil shown in capacity chart (Figure 5C).

Installation Instructions for Vent Plug

  1. Determine position of reducer after equipment has been installed. (See Figure 5A).
  2. Remove solid pipe plugs & install vent plug in position indicated by drawings. (Other positions may cause leakage).
  3. If reducer is mounted in position “C” or “D”, remove oil level plug & insure that oil is up to this hole. If not, add oil until it comes up to this level (approx. 1/4 qt in the 4A, 1/2 qt in the 5A). To add oil, remove pipe plug or vent at the uppermost part.
  4. Position “F” not recommended-premature oil leakage may occur around input shaft seal. Use this position only if no other will work.

Removal & Installation

If the speed reducer is removed from the conveyor for maintenance purposes, the following precautions should be taken upon reinstalling the reducer:

  1. When the reducer is used in conjunction with sheaves and sprockets, care should be taken to insure that shafts are parallel and sheaves and/or sprockets are in alignment. This will prevent damage to bearings, chain and sprockets, sheaves and V-Belts.
  2. Sheaves and sprockets should be properly keyed and tightened to the shafts to prevent wear to the shaft and bores. Extreme belt or chain tension should be avoided.
  3. When assembling sheaves or sprockets on reducer shafts, they should be installed as close to the reducer housing as possible. Sheaves or sprockets should not be driven onto the shaft. This could result in damage to bearings and/or reducer housing.

“C” Face Motors

Models 4AC and 5AC speed reducers are supplied with a “C-Face” adapter and are coupled directly to the motor by coupling gears and sleeve. To replace the coupling, refer to Figure 5D and follow the instructions listed below.

  1. Install 3/4” bore coupling gear to reducer shaft using 3/16” x 1” long shaft key. Tighten set screws through hole in “C-Face” adapter.
  2. Install coupling gear to motor (refer to chart for correct bore size). Locate 2-1/32” from face of motor using 3/16” x 1” long shaft key. Tighten set screws.
  3. Place sleeve onto coupling gear on motor and ease motor into place (look through hole in “C-Face” adapter to see that sleeve seats onto coupling gear of reducer).
  4. Align motor mounting holes to “C-Face” adapter and install mounting bolts.
  5. “C” – face adapters use a plastic coupling to connect the motor shaft to the reducer input shaft. A gear is mounted to the end of each shaft. The gears nest inside the plastic coupling.

It is important for these gears to be properly spaced on the shafts. Incorrect gear setting can result in excessive coupling noise and bearing failure.
The Hytrol Motor Coupler Gage should be used to space coupling gears whenever the motor or reducer is changed out. The Motor Coupler Gage is a plastic template that mounts over the motor flange or the reducer adapter. This gage will accurately locate both gears to their correct setting on the shaft. The illustration on the face of the gage shows how to use it.
