  12. 12. Jacton Electromechanical Co.,Ltd http://www.screw-jack.com12Operation ManualPlease read this entire document prior to operating the miter gearbox. Miter gearbox failure or injuryto operators may be caused by improper installation, operation or maintenance.InstallationMiter gearboxs must be mounted on a rigid, structurally sound baseplate. Ensure that miter gearboxmounting pads rest evenly on the baseplate. The use of shims may be required to avoid housingdistortion which could alter the gear mesh or cause premature bearing failure.The miter gearbox may be driven by direct coupling, flexible coupling, or V-belt drive. Couplersshould require only a light force to install. The driveline must be accurately aligned within theequipment manufacturers requirements to limit operating loads and minimize thrust loads on themiter gearbox shaft. V-belt drives must be mounted close to the housing to minimize excessiveoverhung loading which could result in early bearing or shaft failures. Sheaves must fit correctly. Atinstallation, a tight forced fit could move the shaft from its normal position and cause internal damage.A loose fit could induce excessive vibration during operation and cause shaft damage or breakage.WarningWhen mounting the miter gearbox, the buyer is responsible to properly determine the quality or gradeof fastener, thread engagement, load carrying capacity, and torque requirements.WarningThe buyer is responsible to provide protective shields over all external rotating parts, couplers, orshaft extensions mounted on or with the miter gearbox. Protective clothing must be worn wheninstalling or maintaining the miter gearbox and operating system.Initial operation should be carried out under no-load conditions. Before applying power to the mitergearbox installation, review the following:1. Check tightness of mounting bolts.2. Check for proper oil level in miter gearbox.3. Be certain that tools, debris, etc., are clear from rotating parts.4. Rotate shafts by hand. If they do not rotate freely, check for uneven mounting, couplingmisalignment or excessive belt tension.If all tests are satisfactory, make connections to shafts, ensure that all safety devices are in place,and begin operation.LubricationAll miter gearboxes are factory tested prior to shipment. They include the correct amount of oil unlessspecified by the customer to be shipped dry. Shaft bearings are splash lubricated and partiallysubmerged in oil when the miter gearbox is mounted horizontally. After installation, remove thedipstick and verify correct oil level. If no dipstick is provided, determine level by any appropriatemethod. In general, the oil level should be approximately half the depth of the miter gearbox (to theparting line) for horizontal mounting, or to the shaft centerlines, if mounted other than horizontally.CautionPrior to operation, make sure the miter gearbox contains the correct amount of oil. If under-filled orover-filled, damage to the miter gearbox or injury to personnel may result.
  13. 13. Jacton Electromechanical Co.,Ltd http://www.screw-jack.com13Approved Lubricants:For miter gearboxs operating in an ambient temp of –20 Deg. C and +85 Deg. CMiter gearbox lubricant brand is VG220 (ISO viscosity class)When low speed less than 100Rpm, optional grease lubricantCautionDonot combine synthetic with non-synthetic oils in the miter gearbox.MaintenanceWarningDisconnect power prior to any maintenance and do not bypass or inactivate any safety or protectivedevice. Lock out and tag the power supply to prevent unexpected application of power.Routinely inspect mounting bolts, couplers,or other power transmitting devices to ensure all parts arefirmly anchored.Keep shafts and vent plugs (when included) clean to prevent foreign particles fromentering seals or housing. Inspect daily for any oil leaks and any unusual noises. Inspect weekly forend play in shafts. Inspect belt drive tension after the first ten hours of operation and periodicallythereafter.Check the oil level every 24 hours of operation. In the beginning to change the oil when the mitergearbox has been in service for two weeks or 100 ~ 200 hours. Routine oil change intervals will varyfor each particular installation depending on the severity of the environment. Normal changes shouldoccur half ~ 1year or 1000 ~ 2000 hours of operation. The longest life at continuous service will berealized when the oil temperature does not exceed +85 deg. C. For oil substitutions, or for high inputspeeds, contact Jacton engineers.WarningDonot change or add oil while the miter gearbox is running. Damage to the miter gearbox or injury topersonnel may result. The miter gearbox housing, oil, plugs, and associated components may reachhigh temperatures and cause severe burns. Use extreme care when servicing the miter gearbox.Trouble Shooting
  14. 14. Jacton Electromechanical Co.,Ltd http://www.screw-jack.com14Frequently Asked QuestionsHow Do I Know Which Shaft Of Miter gearbox Is As Input Shaft?When using a 1:1 ratio gearbox ,it does not matter which shaft is used as the input shaft. Normally,X-shaft is input shaft, Y-shaft is output shaft. For other reduction gear ratios input shaft is same as 1:1ratio gearbox, but for increasing gear ratios input shaft, which is Y-shaft is input shaft, X-shaft isoutput shaft.Can I Use Miter gearbox As Speed Increaser?All miter gearbox can be used as speed increaser, by inputting on the output side of the gearbox,however it is important to check whether the miter gearbox can handle the power and speed. Whenusing as an increaser, the input speed does not exceed the specifications recommended maximumspeed. Special gearbox is available where the pinion can be put on the through shaft so that twooutput shaft increase the speed.Are Miter gearboxes Supplied Filled With Gear Oil?Yes, all miter gearboxes are filled gear oil prior to shipment, customers can install them and use themdirectly. Note: for low speed applications (100 rpm input speed and below) miter gearboxes may berecommended to have grease lubrication.How Often Should I Change Gear Oil In The Miter gearbox?Check the gear oil level every 24 hours of operation. In the beginning to change the gear oil when themiter gearbox has been in service for two weeks or 100 ~ 200 hours. Routine oil change intervals willvary for each particular installation depending on the severity of the environment. Normal changesshould occur half ~ 1year or 1000 ~ 2000 hours of operation. The longest life at continuous servicewill be realized when the oil temperature does not exceed +85 deg. C. For oil substitutions, or for highinput speeds, contact Jacton engineers.How Transmission Efficiency Of Miter gearbox?The miter gearbox transmission efficiency up to 98%
