Technique of Belt Tensioning
one. Calculate the deflection distance in mm on a basis of 16mm per meter of span. Center distance(m) x 16=Defection(mm).
two. Use a spring stability and rule measure the force from the belt, when the worth falls within the values given, the drive must be satisfactory. Othewise, utilize the Torque arm’s turnbuckle adjust the tension of the belt. (Note, the force course as well as the belt need to be a suitable angle).

SMR Gearbox Installation
Satisfactory overall performance depends upon proper set up. lubrication and servicing. thus it is vital that the instructions while in the installation and maintenance leaflet. supplied with every gearbox. are followed carefully. a few of the significant facets of belt and torque-arm installation are listed beneath.
one. Install pulley on gearbox input shaft as close on the reducer feasible, and mount reducer on driven shaft as shut to bearing as practical. failure to perform this will trigger excess loads inside the input shaft bearings and output bearings and could cause their premature failure.
two. Install motor and wedge belt drive using the belt pull at around 90° for the center line amongst driven and input shafts. this can permit tensioning in the wedge belt drive with all the torque arm which need to ideally be in tension. if output hub runs anti-clockwise. torque arm should be positioned the best.
three. lnstall torque-arm fulcrum on a rigid assistance to ensure the torque-arm are going to be at about proper angles towards the center line through the driven shaft and also the torque arm case bolt. make sure there is adequate consider up in the turnbuckle for belt tension adjustment.
Preserve close.
Bell drive might be located in any practical postion. when the torque arm will be to be applied to tighten the belts, the drive needs to be at about tight angle to the line amongst the input and output shafts.
Bell drive could be located for the appropriate if preferred.
If output hub rotates clock-wise. position belt drive and torque arm in opposite direction to that shown while in the illustration.
Torque arm and belt get up.
Torque arm may be mounted for the ideal if wanted.

how you can order the SMR gear box
Gearbox Coding
Gearbox coding
Initially 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 demanded: 1 conventional metric bore. two substitute metric bore.
Example
Size e unit 20:1 nominal gear ratio, shaft mounted with typical metric hub bore (55mm): SMR-E2001
It backstop are needed, these needs to be order individually. and have to specify the output hub rotation. E.g.: SMR-E2001 complete with backstop. inside the input shaft side, the output hub’s rotation is in clockwise.
optional Extras
Backstops
A backstop may perhaps be integrated on applications the place it is actually essential to avert reversal of rotation. it is actually promptly 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 style and design is this kind of the reducer is often bolted direct to supporting framework. this flange mounting utilization of the reducer may well permit designers to omit a bearing or pillow block, however it does. naturally. eliminate the straightforward belt adjustment function characteristic of shaft mount.
Note: Common SMR gearbox will not drill mount screws. when buyer need to have these kinds mount, please specify inside the order.

Shaft Mount Reducer are metric in style throughout and also have energy ratings to AGMA typical. Shaft Mount Reducers present a really effortless technique of cutting down speed, because it is mounted directly around the driven shaft rather than requiring foundations of its personal. It eliminates the usage of one particular, and occasionally two, versatile couplings and external belt take-up arrangements, A torque-arm anchors the reducer and supplies swift, uncomplicated adjustment of the Wedge Belts by means of its turnbuckle.
Shaft Mount Reducers are produced in eight gear situation sizes, nominal gear ratios are five:1, 13: 1 and twenty: one, A really broad preference of ultimate driven speeds is often determined from the utilization of an proper input Wedge Belt Drive.
The units will generally be oil lubricated, but they are equally suitable for lengthy daily life synthetic lubricants.
Figure out the output speed in the gear units, multiply the absorbed energy (or Motor energy if absorbed energy nit regarded) by the service issue selected in stage one.
Note: Gear units are momentarily capable of transmitting twice (2X) the rated capacity on start off or through operation.
Unit variety
The selection of single or double reduction gearbox is going to be determined by the output pace expected . The normal working speeds for every on the gearboxes may be observed inside the electrical power rating and belt drive tables.

one.0utput Velocity
Refer to the Drive Choice Tables and beneath the appropr-late gearbox dimension and ratio read through down the column headed ‘Output Speed’until an Output Speed equal or close to to that necessary is found. The suggested gearbox ratio is offered from the first column
2.Pulley Diameters
Read across from your selected output pace to get the two driving and drives pulley pitch diameters, groove segment along with the acceptable amount of belts.
Note: in lots of situations one particular belt is advisable, staying satisfactory for electrical power transmission functions
3.Center Distance
Belt length and center distance can be observed by referring for the ideal pages with the “Wedge Belt Drives” catalogue.
Variety of linked belt for driving speeds other than 1440 rpm
