SMR Gearbox Installation
Satisfactory efficiency is determined by right installation. lubrication and servicing. thus it is necessary the instructions within the set up and servicing leaflet. provided with every gearbox. are followed carefully. a number of the vital elements of belt and torque-arm set up are listed under.
1. Install pulley on gearbox input shaft as shut for the reducer achievable, and mount reducer on driven shaft as near to bearing as sensible. failure to perform this will cause excess loads from the input shaft bearings and output bearings and could result in their premature failure.
2. Install motor and wedge belt drive using the belt pull at around 90° for the center line among driven and input shafts. this will likely permit tensioning of your wedge belt drive with all the torque arm which need to preferably be in stress. if output hub runs anti-clockwise. torque arm must be positioned the correct.
three. lnstall torque-arm fulcrum on the rigid assistance in order that the torque-arm will probably be at approximately appropriate angles to your center line through the driven shaft as well as the torque arm case bolt. ensure there is adequate get up while in the turnbuckle for belt tension adjustment.
Preserve shut.
Bell drive can be located in any practical postion. should the torque arm is to be used to tighten the belts, the drive ought to be at about tight angle towards the line amongst the input and output shafts.
Bell drive may be located towards the proper if preferred.
If output hub rotates clock-wise. place belt drive and torque arm in opposite direction to that proven during the illustration.
Torque arm and belt take up.
Torque arm might be mounted to your appropriate if sought after.

the way to buy the SMR gear box
Gearbox Coding
Gearbox coding
Initially 3 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 pace reducer two flange mount
Eighth digit: signifies output hub bore demanded: 1 common metric bore. 2 alternative metric bore.
Example
Dimension e unit twenty:1 nominal gear ratio, shaft mounted with normal metric hub bore (55mm): SMR-E2001
It backstop are required, these really should be purchase individually. and have to specify the output hub rotation. E.g.: SMR-E2001 comprehensive with backstop. inside the input shaft side, the output hub’s rotation is in clockwise.
optional Extras
Backstops
A backstop may possibly be integrated on applications where it truly is required to reduce reversal of rotation. it truly is promptly set up within the reducer, by basically removing a cover plate
Note: For ratio 5: one gear box, backstop tend not to proposed.
Flange mounting
SMR situation layout is this kind of that the reducer is often bolted direct to supporting framework. this flange mounting utilization of the reducer could permit designers to omit a bearing or pillow block, but it does. obviously. eradicate the quick belt adjustment function characteristic of shaft mount.
Note: Conventional SMR gearbox usually do not drill mount screws. when buyer have to have these types mount, please specify from the purchase.

Shaft Mount Reducer are metric in design and style during and also have electrical power ratings to AGMA typical. Shaft Mount Reducers offer an extremely hassle-free method of minimizing velocity, since it is mounted immediately to the driven shaft instead of requiring foundations of its own. It eliminates using one particular, and from time to time two, flexible couplings and external belt take-up arrangements, A torque-arm anchors the reducer and presents rapid, straightforward adjustment of your Wedge Belts by way of its turnbuckle.
Shaft Mount Reducers are produced in eight gear situation sizes, nominal gear ratios are five:1, 13: one and twenty: one, A very wide decision of ultimate driven speeds could be determined by the use of an acceptable input Wedge Belt Drive.
The units will normally be oil lubricated, however they are equally suitable for lengthy daily life synthetic lubricants.
Ascertain the output speed in the gear units, multiply the absorbed electrical power (or Motor energy if absorbed energy nit acknowledged) from the service aspect chosen in step 1.
Note: Gear units are momentarily capable of transmitting twice (2X) the rated capability on get started or during operation.
Unit variety
The preference of single or double reduction gearbox might be determined by the output speed required . The standard working speeds for every in the gearboxes may be observed in the energy rating and belt drive tables.
Note : When use 5:1 Gear Units, the Back cease usually do not recommended.
choice of linked belt drive for 1440 rpm electrical motors
1.0utput Pace
Refer on the Drive Selection Tables and beneath the appropr-late gearbox size and ratio go through down the column headed ‘Output Speed’until an Output Speed equal or close to to that required is discovered. The suggested gearbox ratio is offered in the 1st column
2.Pulley Diameters
Study across from your selected output velocity to obtain each driving and drives pulley pitch diameters, groove area along with the acceptable number of belts.
Note: in many circumstances a single belt is suggested, getting ample for electrical power transmission functions
3.Center Distance
Belt length and center distance may be discovered by referring towards the suitable pages of the “Wedge Belt Drives” catalogue.
Selection of related belt for driving speeds aside from 1440 rpm
1.Gearbox input Shaft Speed
Multiply the gearbox output pace by the Exact GEAR RATIO to obtain the gearbox input shaft pace.
