SMR Gearbox Installation
Satisfactory functionality will depend on proper set up. lubrication and maintenance. therefore it is important that the directions while in the installation and maintenance leaflet. supplied with every single gearbox. are followed cautiously. several of the essential facets of belt and torque-arm set up are listed beneath.
1. Install pulley on gearbox input shaft as close to your reducer doable, and mount reducer on driven shaft as shut to bearing as useful. failure to carry out this can result in extra loads within the input shaft bearings and output bearings and could bring about their premature failure.
2. Install motor and wedge belt drive with all the belt pull at about 90° to your center line involving driven and input shafts. this will allow tensioning from the wedge belt drive with the torque arm which should really ideally be in tension. if output hub runs anti-clockwise. torque arm need to be positioned the appropriate.
3. lnstall torque-arm fulcrum on a rigid help to ensure the torque-arm is going to be at roughly ideal angles towards the center line with the driven shaft plus the torque arm case bolt. ensure that there is certainly enough take up during the turnbuckle for belt stress adjustment.
Retain close.
Bell drive may be situated in any effortless postion. in the event the torque arm is always to be employed to tighten the belts, the drive must be at about tight angle on the line concerning the input and output shafts.
Bell drive could be situated for the suitable if wanted.
If output hub rotates clock-wise. position belt drive and torque arm in opposite route to that proven within the illustration.
Torque arm and belt consider up.
Torque arm could possibly be mounted towards the ideal if desired.

ways 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. indicates assembly: O shaft mounted velocity reducer two flange mount
Eighth digit: indicates output hub bore expected: one regular metric bore. two substitute metric bore.
Instance
Size e unit twenty:one nominal gear ratio, shaft mounted with common metric hub bore (55mm): SMR-E2001
It backstop are needed, these must be buy individually. and have to specify the output hub rotation. E.g.: SMR-E2001 total with backstop. inside the input shaft side, the output hub’s rotation is in clockwise.
optional Extras
Backstops
A backstop could be incorporated on applications in which it is actually necessary to stop reversal of rotation. it can be quickly installed inside the reducer, by just removing a cover plate
Note: For ratio 5: one gear box, backstop do not proposed.
Flange mounting
SMR situation style is such the reducer may be bolted direct to supporting framework. this flange mounting use of the reducer may possibly allow designers to omit a bearing or pillow block, however it does. naturally. reduce the easy belt adjustment characteristic characteristic of shaft mount.
Note: Typical SMR gearbox never drill mount screws. when client have to have these sorts mount, please specify during the order.

Shaft Mount Reducer are metric in design throughout and also have electrical power ratings to AGMA normal. Shaft Mount Reducers supply a really effortless system of cutting down velocity, because it is mounted immediately to the driven shaft in lieu of requiring foundations of its own. It eliminates using a single, and in some cases two, versatile couplings and external belt take-up arrangements, A torque-arm anchors the reducer and presents speedy, simple adjustment with the Wedge Belts by means of its turnbuckle.
Shaft Mount Reducers are manufactured in eight gear situation sizes, nominal gear ratios are five:1, 13: one and twenty: 1, A really broad preference of last driven speeds might be determined by the utilization of an appropriate input Wedge Belt Drive.
The units will typically be oil lubricated, but they are equally appropriate for prolonged life synthetic lubricants.
Identify the output velocity with the gear units, multiply the absorbed power (or Motor power if absorbed energy nit known) from the services aspect selected in phase one.
Note: Gear units are momentarily capable of transmitting twice (2X) the rated capacity on commence or for the duration of operation.
Unit selection
The alternative of single or double reduction gearbox will probably be established by the output speed essential . The usual working speeds for each of the gearboxes may be observed in the power rating and belt drive tables.
Note : When use five:one Gear Units, the Back prevent tend not to recommended.

1.0utput Speed
Refer for the Drive Selection Tables and beneath the appropr-late gearbox size and ratio study down the column headed ‘Output Speed’until an Output Speed equal or near to that needed is found. The suggested gearbox ratio is offered within the initial column
two.Pulley Diameters
Go through across from the selected output velocity to obtain the two driving and drives pulley pitch diameters, groove section as well as ideal quantity of belts.
Note: in many instances one belt is advised, getting ample for power transmission functions
three.Center Distance
Belt length and center distance is often uncovered by referring to your suitable pages with the “Wedge Belt Drives” catalogue.
Variety of linked belt for driving speeds other than 1440 rpm
