ASSEMBLY INSTRUCTIONS 1- Install drive end assembly to the end of a conveyor frame, bolt together with 1/2 x 1 1/4 hex. bolt, lock washers and nuts. 2- Install pan section sides on the conveyor frame slide the hinge pin through the slotted cross members at the ends of the frame section, as shown, fix the hinge to the pan section with 3/8 x 3/4 carriage bolts, lock washers and nuts. 3- Bolt together conveyor frames with 1/2 x 1 x 1/4 hex bolts, lock washers and nuts. 4- Fix a return roller support with a round hole on one side and one with a D hole on the other side to the tabs on the bottom tubes of the frame with 3/8 x 3/4 car. bolt, lock washers and nuts 6- Secure return roller assembly between the supports with a cutter pin. 7- Bolt idler end assembly to the end of the conveyor sections, use 1/2 x 1 1/4 hex. bolts, lock washers and nuts. 8- Put some never seez or grease on motor shaft to make it easier to remove for later maintenance, install the key and fix it to the gear box with bolts. 9- Assemble hopper supports to idler end frame but don t tight the bolts before installing conveyor belt. 10- Assemble hopper sides to hopper end and the assembly to the hopper supports. 5- Bolt together conveyor frame weldments, use 1/2 x 1 1/4 hex. bolt, flat washers, locks washers and nuts. 7
INSTALLATION OF "ALLIGATOR" STAPLE BELT FASTENER Length of belt required: Twice the length of conveyor sections plus 9 feet 6 inches. 1- Lay out belt on a solid work surface, (a piece of plywood laid on section makes a handy work bench), set a framing square along belt and cut at 90 degree angle with utility knife. IMPORTANT: A square cut is necessary for the belt to run straight on the rollers. 2- Center fastener strip on belt. Figure no.1 7- Repeat the procedure at each end of the belt to secure the fastener strip. Follow the sequence as shown in figure no.2. IMPORTANT: The word "ALLIGATOR" on fasteners should face up 3- Place the applicator tool in the center of the fastener strip. Push applicator and fastener strip tight against the belt end. Set cam levers firmly in place away from belt. See figure no.1 4- Insert staples. Use a staple dispenser or place individual staples in slot by hand. 5- VERY IMPORTANT: Position staple driver in applicator and push staples down by hand until staples contact belt. Otherwise staples can wander when driven by hammer. 6- Using lightweight hammer, strike staple driver until staple clinches on the anvil. Do not overdrive staples as fastener can be distorted. Figure no.2 8- After all staples are driven, turn the belt over and with a flat steel plate under the fastener strip, peen the staples ends flush with the surface of fastener strip. IMPORTANT: Be careful not to crush fastener loops. 8
9- Notch belt as needed in order to keep the belt from catching conveyor frame work, see figure no.3 10- After applying fasteners to both ends of belt, mesh loops together and insert hinge pin. Use pliers to crimp hinge pin retaining washers on to pin ends. Figure no.3 CONVEYOR BELT Run belt on top of the conveyor sections, around idler end, over the return wheels assemblies and over tension rollers and around the drive roller and back on top of the sections, see figure no.4. NOTE : Make certain idler roller is all the way in. DRIVE IDLER END Figure no.4 9
TRACKING BELT Start by making sure that the adjuster bolts at the idler are tightened equally. The primary rule of tracking a conveying belt is : the belt moves towards that end of the pulley where it contacts first. If the belt moves to one side, move that end of the pulley out or the other end of the pulley in. CAUTION : Don t take chances, make sure everyone is clear of machine before operating. 1. Turn on motor and check to see if belt runs centered on drive roller. 2. If adjustment is necessary, TURN OFF MOTOR, loosen bearing bolts on adjusting screw side, loosen also gear box brackets bolts and also the gear box bolts in order to allow the gear box to move and stay in line as the drive roller is moved outward or inward. If the belt moves to the gear box side, move the end of the roller out, if the belt moves to the opposite side, move the end of the roller in. 3. Tighten all the bolts. 4. Run conveyor and check belt alignment, if further adjustments are necessary, repeat steps 1, 2, 3. 5. Check to see if belt runs centered on the idler roller. 6. If adjustment is necessary TURN OFF MOTOR and, with adjusting nut, move right end of the idler roller out if belt runs off the right or move left end of the idler roller out if the belt runs off the left. 7. Run conveyor and check belt alignment, if further adjustments are necessary, repeat step. BASIC RULES FOR TIGHTENING A CONVEYING BELT There is no formula for setting the proper tension of a carrying belt. Belt tension must be tight enough to: A) Prevent slippage between the drive pulley and the belt. B) Force the belt to conform to the crown on the crowned pulleys Belt tightening is done by means of the adjusting rods at the idler end. NOTE: When tracking the belt, allow the belt to run several minutes and at least three full belt revolutions to determine if additional adjustement si required. Check tracking while machine is loaded. Check tracking during the first 2-10 hours after start up. Check tracking periodically afterwards. 10
STARTING UP CAUTION : Don t take chances, make sure everyone is clear of machine before running. It may take many hours of running, under full load, for the gears their to reach highest efficiency. The gearbox may, if necessary, be put to work under full load immediately. However, it is better for the ultimate life of the gear to be run under gradually increasing loads (reaching the full load after about 20 to 40 hours) Temperature rise on the initial run will be higher than the temperature eventually reached after the gearbox is fully run-in. IMPORTANT: Reasonable precautions should be taken to avoid overloads in the early stage of running. MAINTENANCE CAUTION: Make sure the power is off before inspection. To maintain free ventilation of the gear box, the breather hole in the filler plug (air-vent) should be kept clear at all times. Regularly inspect set screw and reducer mounting bolts for tightness because loose fasteners can cause misalignment and excessive wear. - Check oil in gear box. - Grease flange bearings at drive and idler ends. - Oil chain on power brush. Use light weight oil. MONTHLY LUBRICATION CHANGING LUBRICANT - After 100 hours of running, a new worm gear unit should be drained, flushed and refilled with proper oil. - Oil should be changed at least every 2500 operating hours or every 6 months, whichever occurs first. - Never mix 2 different types of oil. Be sure to drain and wash before using another type of oil. 11
SELECTION OF LUBRIFICANT Lubricating oil must have a viscosity sufficient to reduce friction and allow the speed reducer to operate smoothly under high load and impact. Consult table below for the choice of lubricant. Where the temperature range is expected, the synthetic oil EXXON SHC 629 is recommended. Please keep in touch with our engineering department, especially when operating reducers under special conditions such as high or low speed, high temperature or heavy loads.
