INTRODUCTION

This service manual pertains to the disassembly and assembly of CAMCO’s 1.5 link, 2.0 link, 3.0 link, 4.5 link, and 6.0 link “Table Top” Precision Link Conveyors and CAMCO’s 6.0 and 9.0 “HeavyDuty” Precision Link Conveyors.

The CAMCO Precision Link Conveyor comes in two types: “over and under” and “carousel”. Both are driven by a CAMCO Index Drive containing cam followers and a precision ground cam. Inspection and service on the Index Drives is covered in a separate Service Manual for the specific model Index Drive.

This manual is to be used in conjunction with the "General Service Manual" which describes the lubrication and general maintenance of CAMCO Index Drives.

Drawings of the various size links are included in this manual. The procedures in this manual reference the item numbers of these drawings.

Also included is a complete Bill of Materials for your convenience in identifying and ordering spare or replacement parts.

Some users of CAMCO’s Precision Link Conveyors have the facilities and trained personnel to accomplish service repair. You must determine the extent to which intricate servicing should be done in your facility. When in doubt, CAMCO recommends that CAMCO trained serviceman make the repairs.

GENERAL DESCRIPTION

The CAMCO Precision Link Conveyor is a precision mechanical device that requires no internal adjustment during its expected service life when operated within rated loads and speeds.

All CAMCO Precision Link Conveyors employ the “link on link” design, meaning all links are identical to each other and can be used for fixture mounting, rather than the “link on spacer bar” design which permits only every other link to be used for fixture mounting.

The connection of the two links consists of a precision ground link pin (2) with precision needle bearings (1 and 6) in each link ear.

The ends of pins (2) are fitted with precision link pin followers (3) which ride in the main frame guides and support the loads on the face of the link as well as restricting face “in and out” movement.

Each link is furnished with link support cam followers (10) to support loads and eliminate any movement between the link and conveyor main frame.

WARNINGS AND CAUTIONS

Statements in this manual preceded by the words WARNING or CAUTION and printed in italics are very important. We recommend you take special notice of these during service or repair.

WARNING: Means there is the possibility of personal injury to yourself or others.

CAUTION:

Means there is the possibility of damage to the CAMCO unit.

SPARE P AR TS KIT

CAMCO offers a Spare Parts Kit for all CAMCO Precision Link Conveyors. These kits include link pin, needle bearings, followers, locknuts, shims and retaining rings required to rebuild (one) link assembly. These are components that will most likely require replacement during repair of your Conveyor. CAMCO recommends several Spare Parts Kits be purchased and kept on hand to insure against “down time” in the event of damage to the link components.

Individual components may be purchased in any quantity by specifying the part numbers, as noted in the Bill of Materials provided in this service manual.

BEFORE ST ARTING

Before starting disassembly of your CAMCO unit you should read and review the following instructions. These provide important information on parts and procedures necessary to successfully complete your repair.

Comply with all Read the “Trouble Shooting Guide” section of your “General Service Manual” before disassem-

bling CAMCO units. CAMCO recommends returning defective equipment for inspection and repair whenever possible.

Warnings and Cautions.

CAMCO uses Loctite to secure all screws and setscrews. If you encounter a fastener that is difficult to remove, apply heat to the screw and remove while still warm.

CONVEYOR LUBRICA TION INFORMA TION

GENERAL

The following is a recommendation for “Clean” Environment “Moderate” Loading and “30” Cycles per min.

Lubrication of the CAMCO’s Precision Link Conveyors is largely dependent upon Work Environment, Conveyor Loading and Cycle Rate, therefore a “standard” lube interval can-

Lubrication should be done at Take-Up end of the conveyor with the link in dwell and the motor stopped.

LUBRICATION OF SPROCKET BEARINGS

The flange bearings supporting the Sprocket/ Input Shaft should be lubricated, approx. every 2000 working hours, with NGLI #3 bearing grease.

LUBRICATION OF PRECISION LINKS

Followers equipped with lube fitting should be given a shot of Lithium Soap grease having a #1 consistency at least once every 2000 hours of operation, or 6 months, whichever is less.

In order to lubricate the link support followers (10), it may be necessary to remove any mounting fixtures or tooling which may have been added by the machine builder other than

OIL CAN APPLICATION BETWEEN THE LINK AND FOLLOWER AT BOTH ENDS OF LINK PIN

CAMCO, if provisions have not been made to access these lube fittings.

To lubricate the link pin followers (3), the conveyor drive should be placed in dwell, at which time the lube fittings can be accessed through the holes provided in the straight or radical guides. Index once and repeat the procedure until all the links have been lubricated.

NOTE: Both top and bottom guide rails (car-

ousel), and left and right guide rails (over and under) have the lube access holes. Both should be lubricated.

NOTE: If only one access hole is provided in

each side, it may be necessary to hand crank the reducer until the lube fittings appear. Repeat this procedure until all links have been lubricated.

CHAIN OR IDLER LUBRICA TION

LINE SHAFT LUBRICA TION

All idlers (chain or belt) are supplied with a grease fitting and should be lubricated at least once a month. Roller chains are used in some applications to drive the line shaft or provide power to optional equipment such as indexers, oscillators, pick and place units, etc. These chains should be brushed periodically with a light machine oil. Timing belts do not require any lubrication.

OIL SEAL INST ALLA TION RECOMMENDA TIONS

We recommend that all seals be replaced anytime the device is being disassembled whether they are damaged of not, as most damage to oil seals occurs at assembly when recommended practice for seal installation is generally not followed.

Check dimensions to be sure that shaft and bore diameters match those specified for the seal selected.

Check seal for damage that may have occurred prior to installation. A sealing lip that is turned back, cut or otherwise damaged should be replaced.

Check bore to see that leading edge is deburred. A rounded corner or chamfer should be provided.

Check shaft and remove surface nicks, burrs and grooves and look for spiral machine marks that can damage the seal lip.

Check shaft end and remove burrs or sharp edges. Where the installation requires the shaft seal against the sealing lip, the shaft end should be chamfered.

On conveyors supplied with a line shaft or power take-off shaft, provisions have been made in the support bearings of these shafts for periodic lubrication. These bearings are to be greased at least once every 500 hours of operation with EXXON Andok “C” or equivalent NGLI #4 bearing grease.

GENERAL MAINTENANCE LUBRICA TION

The general condition of all unpainted components should be observed periodically and given a light spray of machine oil as required to retard rust.

the edges of the spline or keyway as much as possible and lubricate with a hard, fibrous grease.

Check seal direction making sure that the new seal faces in the same direction as the original. Generally, the lip faces the lubricant or fluid to be sealed.

Prelubricate the sealing element before installation by wiping with lubricant being retained.

Use correct installation tool — press fitting tools should have an outside diameter

0.010" smaller than the bore size. If possible, center of tool should be relieved so that pressure is applied only at the OD.

10.

Use proper driving force, where possible an arbor press; otherwise, a dead blow hammer to avoid popping the spring out of the seal. NEVER HAMMER DIRECTLY ON THE SURFACE OF THE SEAL.

11.

Bottom out the tool or seal to avoid cocking the seal in the bore. This also positions the seal correctly on the shaft.

Check splines and keyways for sharp edges and protect the seal lip with an assembly sleeve or shim stock. If not available, round

12.

Check for parts interference from other machine parts that might rub against the seal to cause friction and damaging heat.
