SMR Gearbox Installation
Satisfactory efficiency relies on proper set up. lubrication and maintenance. for that reason it is crucial the directions inside the installation and upkeep leaflet. provided with every single gearbox. are followed very carefully. some of the essential aspects of belt and torque-arm installation are listed beneath.
one. Install pulley on gearbox input shaft as shut to the reducer doable, and mount reducer on driven shaft as shut to bearing as useful. failure to complete this may result in excess loads from the input shaft bearings and output bearings and could induce their premature failure.
two. Install motor and wedge belt drive with all the belt pull at approximately 90° towards the center line amongst driven and input shafts. this will permit tensioning on the wedge belt drive using the torque arm which should preferably be in stress. if output hub runs anti-clockwise. torque arm need to be positioned the correct.
three. lnstall torque-arm fulcrum on the rigid assistance in order that the torque-arm will probably be at about right angles on the center line through the driven shaft as well as the torque arm case bolt. be sure there’s enough consider up while in the turnbuckle for belt stress adjustment.
Hold shut.
Bell drive might be situated in any practical postion. in case the torque arm will be to be utilized to tighten the belts, the drive ought to be at about tight angle on the line involving the input and output shafts.
Bell drive could be positioned to your right if sought after.
If output hub rotates clock-wise. position belt drive and torque arm in opposite path to that shown inside the illustration.
Torque arm and belt consider up.
Torque arm may be mounted towards the proper if wanted.

ways to buy 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 normal metric bore. two alternative metric bore.
Illustration
Dimension e unit 20:one nominal gear ratio, shaft mounted with common metric hub bore (55mm): SMR-E2001
It backstop are essential, these must be purchase separately. and need to specify the output hub rotation. E.g.: SMR-E2001 finish with backstop. within the input shaft side, the output hub’s rotation is in clockwise.
optional Extras
Backstops
A backstop might be incorporated on applications in which it truly is required to reduce reversal of rotation. it’s quickly put in inside the reducer, by just getting rid of a cover plate
Note: For ratio 5: one gear box, backstop will not proposed.
Flange mounting
SMR case layout is such that the reducer might be bolted direct to supporting framework. this flange mounting use of the reducer may allow designers to omit a bearing or pillow block, but it does. naturally. get rid of the straightforward belt adjustment attribute characteristic of shaft mount.
Note: Normal SMR gearbox tend not to drill mount screws. when client will need these varieties mount, please specify within the purchase.

Shaft Mount Reducer are metric in design throughout and also have energy ratings to AGMA standard. Shaft Mount Reducers provide a really easy approach of cutting down speed, because it is mounted right within the driven shaft as an alternative to requiring foundations of its own. It eliminates using one particular, and from time to time two, versatile couplings and external belt take-up arrangements, A torque-arm anchors the reducer and presents swift, straightforward adjustment on the Wedge Belts by means of its turnbuckle.
Shaft Mount Reducers are produced in eight gear case sizes, nominal gear ratios are five:one, 13: one and twenty: 1, An incredibly wide choice of ultimate driven speeds is often determined through the utilization of an appropriate input Wedge Belt Drive.
The units will usually be oil lubricated, nevertheless they are equally ideal for extended lifestyle synthetic lubricants.
Identify the output speed on the gear units, multiply the absorbed electrical power (or Motor energy if absorbed electrical power nit identified) from the service component picked in phase 1.
Note: Gear units are momentarily capable of transmitting twice (2X) the rated capacity on commence or all through operation.
Unit choice
The selection of single or double reduction gearbox will likely be established through the output velocity necessary . The typical working speeds for every with the gearboxes might be observed while in the electrical power rating and belt drive tables.

1.0utput Velocity
Refer on the Drive Assortment Tables and beneath the appropr-late gearbox dimension and ratio go through down the column headed ‘Output Speed’until an Output Speed equal or near to that needed is found. The recommended gearbox ratio is provided while in the very first column
two.Pulley Diameters
Read across in the picked output speed to get each driving and drives pulley pitch diameters, groove part and also the ideal variety of belts.
Note: in many circumstances a single belt is recommended, staying adequate for electrical power transmission functions
3.Center Distance
Belt length and center distance is usually discovered by referring to the proper pages in the “Wedge Belt Drives” catalogue.
