SMR Gearbox Installation
Satisfactory functionality depends upon suitable installation. lubrication and servicing. therefore it’s important that the instructions during the installation and maintenance leaflet. provided with every gearbox. are followed very carefully. a number of the critical facets of belt and torque-arm installation are listed below.
one. Install pulley on gearbox input shaft as near on the reducer feasible, and mount reducer on driven shaft as shut to bearing as sensible. failure to try and do this may result in extra loads during the input shaft bearings and output bearings and could bring about their premature failure.
2. Install motor and wedge belt drive using the belt pull at roughly 90° towards the center line among driven and input shafts. this will allow tensioning of the wedge belt drive with all the torque arm which ought to ideally be in tension. if output hub runs anti-clockwise. torque arm ought to be positioned the correct.
3. lnstall torque-arm fulcrum on the rigid support to ensure the torque-arm is going to be at around correct angles for the center line through the driven shaft and also the torque arm situation bolt. ensure that there’s adequate take up during the turnbuckle for belt tension adjustment.
Retain close.
Bell drive might be found in any handy postion. if the torque arm is to be utilised to tighten the belts, the drive needs to be at about tight angle towards the line in between the input and output shafts.
Bell drive could possibly be positioned to your proper if sought after.
If output hub rotates clock-wise. place belt drive and torque arm in opposite course to that shown in the illustration.
Torque arm and belt consider up.
Torque arm may very well be mounted to your right if preferred.

the best way to purchase the SMR gear box
Gearbox Coding
Gearbox coding
To start with 3 letters: SMR
Fourth letter, unit dimension: BCD EFG HJ
Fifth and sixth digits, ratio code: 05 13 twenty
Seventh digit. signifies assembly: O shaft mounted velocity reducer 2 flange mount
Eighth digit: signifies output hub bore needed: 1 regular metric bore. 2 substitute metric bore.
Illustration
Size e unit 20:1 nominal gear ratio, shaft mounted with common metric hub bore (55mm): SMR-E2001
It backstop are necessary, these should be purchase individually. and must specify the output hub rotation. E.g.: SMR-E2001 full with backstop. inside the input shaft side, the output hub’s rotation is in clockwise.
optional Extras
Backstops
A backstop may be integrated on applications wherever it is actually important to prevent reversal of rotation. it can be speedily put in within the reducer, by basically getting rid of a cover plate
Note: For ratio five: one gear box, backstop never encouraged.
Flange mounting
SMR case layout is such that the reducer is often bolted direct to supporting framework. this flange mounting utilization of the reducer might allow designers to omit a bearing or pillow block, nonetheless it does. of course. eradicate the uncomplicated belt adjustment feature characteristic of shaft mount.
Note: Typical SMR gearbox tend not to drill mount screws. when customer want these sorts mount, please specify during the purchase.

Shaft Mount Reducer are metric in style and design all through and also have power ratings to AGMA conventional. Shaft Mount Reducers deliver an incredibly convenient method of lowering velocity, since it is mounted immediately within the driven shaft as an alternative to requiring foundations of its very own. It eliminates the use of 1, and at times two, versatile couplings and external belt take-up arrangements, A torque-arm anchors the reducer and delivers speedy, simple adjustment on the Wedge Belts by way of its turnbuckle.
Shaft Mount Reducers are manufactured in eight gear situation sizes, nominal gear ratios are five:1, 13: one and 20: 1, A very wide preference of ultimate driven speeds is usually established through the utilization of an appropriate input Wedge Belt Drive.
The units will normally be oil lubricated, but they are equally suitable for extended daily life synthetic lubricants.
Ascertain the output pace of the gear units, multiply the absorbed power (or Motor energy if absorbed power nit known) from the services component chosen in phase one.
Note: Gear units are momentarily capable of transmitting twice (2X) the rated capacity on start out or for the duration of operation.
Unit selection
The preference of single or double reduction gearbox will probably be established through the output pace demanded . The regular operating speeds for each in the gearboxes can be observed within the electrical power rating and belt drive tables.
Note : When use five:1 Gear Units, the Back halt do not suggested.
