SMR Gearbox Set up
Satisfactory functionality will depend on suitable installation. lubrication and upkeep. consequently it is crucial the directions during the set up and upkeep leaflet. provided with just about every gearbox. are followed very carefully. a number of the essential aspects of belt and torque-arm set up are listed under.
1. Install pulley on gearbox input shaft as shut to the reducer doable, and mount reducer on driven shaft as close to bearing as sensible. failure to carry out this can bring about extra loads during the input shaft bearings and output bearings and could lead to their premature failure.
2. Install motor and wedge belt drive together with the belt pull at somewhere around 90° to the center line concerning driven and input shafts. this will allow tensioning of your wedge belt drive together with the torque arm which should preferably be in stress. if output hub runs anti-clockwise. torque arm must be positioned the right.
3. lnstall torque-arm fulcrum on the rigid help to ensure that the torque-arm will likely be at roughly suitable angles on the center line with the driven shaft plus the torque arm situation bolt. be sure there exists ample take up while in the turnbuckle for belt stress adjustment.
Continue to keep shut.
Bell drive can be positioned in any convenient postion. in case the torque arm would be to be utilized to tighten the belts, the drive need to be at about tight angle on the line between the input and output shafts.
Bell drive may very well be positioned to your right if sought after.
If output hub rotates clock-wise. place belt drive and torque arm in opposite route to that proven in the illustration.
Torque arm and belt take up.
Torque arm could be mounted to the proper if desired.

tips on how to order the SMR gear box
Gearbox Coding
Gearbox coding
First three letters: SMR
Fourth letter, unit size: BCD EFG HJ
Fifth and sixth digits, ratio code: 05 13 twenty
Seventh digit. signifies assembly: O shaft mounted speed reducer 2 flange mount
Eighth digit: indicates output hub bore expected: one regular metric bore. 2 choice metric bore.
Example
Size e unit 20:1 nominal gear ratio, shaft mounted with conventional metric hub bore (55mm): SMR-E2001
It backstop are required, these should be order separately. and have to specify the output hub rotation. E.g.: SMR-E2001 comprehensive with backstop. during the input shaft side, the output hub’s rotation is in clockwise.
optional Extras
Backstops
A backstop could be integrated on applications the place it is actually necessary to prevent reversal of rotation. it is actually swiftly put in inside the reducer, by merely getting rid of a cover plate
Note: For ratio five: 1 gear box, backstop never proposed.
Flange mounting
SMR case design is this kind of that the reducer might be bolted direct to supporting framework. this flange mounting utilization of the reducer may permit designers to omit a bearing or pillow block, nevertheless it does. of course. eradicate the easy belt adjustment characteristic characteristic of shaft mount.
Note: Conventional SMR gearbox usually do not drill mount screws. when purchaser need these varieties mount, please specify within the order.
