SMR Gearbox Installation
Satisfactory effectiveness is determined by right set up. lubrication and servicing. for that reason it is important the guidelines in the set up and maintenance leaflet. provided with just about every gearbox. are followed thoroughly. several of the essential elements of belt and torque-arm set up are listed below.
1. Install pulley on gearbox input shaft as shut to your reducer feasible, and mount reducer on driven shaft as near to bearing as practical. failure to try and do this can bring about extra loads from the input shaft bearings and output bearings and could lead to their premature failure.
two. Install motor and wedge belt drive together with the belt pull at approximately 90° on the center line amongst driven and input shafts. this will likely allow tensioning with the wedge belt drive with all the torque arm which should ideally be in tension. if output hub runs anti-clockwise. torque arm ought to be positioned the ideal.
three. lnstall torque-arm fulcrum on a rigid help in order that the torque-arm are going to be at approximately suitable angles on the center line with the driven shaft along with the torque arm case bolt. make certain there is certainly sufficient consider up during the turnbuckle for belt tension adjustment.
Retain close.
Bell drive can be found in any practical postion. should the torque arm should be to be employed to tighten the belts, the drive should be at about tight angle towards the line among the input and output shafts.
Bell drive might be positioned to your ideal if preferred.
If output hub rotates clock-wise. position belt drive and torque arm in opposite path to that proven while in the illustration.
Torque arm and belt take up.
Torque arm could be mounted to the correct if wanted.

how you can purchase the SMR gear box
Gearbox Coding
Gearbox coding
First three letters: SMR
Fourth letter, unit dimension: BCD EFG HJ
Fifth and sixth digits, ratio code: 05 13 20
Seventh digit. signifies assembly: O shaft mounted speed reducer two flange mount
Eighth digit: signifies output hub bore essential: one conventional metric bore. 2 alternative metric bore.
Example
Size e unit 20:one nominal gear ratio, shaft mounted with conventional metric hub bore (55mm): SMR-E2001
It backstop are demanded, these ought to be order separately. and will have to specify the output hub rotation. E.g.: SMR-E2001 full with backstop. in the input shaft side, the output hub’s rotation is in clockwise.
optional Extras
Backstops
A backstop could be incorporated on applications where it truly is needed to avert reversal of rotation. it is quickly installed within the reducer, by simply getting rid of a cover plate
Note: For ratio five: one gear box, backstop usually do not proposed.
Flange mounting
SMR situation style and design is such that the reducer is usually bolted direct to supporting framework. this flange mounting use of the reducer may perhaps allow designers to omit a bearing or pillow block, but it does. of course. reduce the straightforward belt adjustment feature characteristic of shaft mount.
Note: Conventional SMR gearbox don’t drill mount screws. when client need these kinds mount, please specify during the purchase.

Shaft Mount Reducer are metric in style throughout and have power ratings to AGMA conventional. Shaft Mount Reducers provide an incredibly handy process of decreasing speed, since it is mounted directly to the driven shaft rather than requiring foundations of its very own. It eliminates the usage of 1, and occasionally two, versatile couplings and external belt take-up arrangements, A torque-arm anchors the reducer and gives fast, effortless adjustment with the Wedge Belts by means of its turnbuckle.
Shaft Mount Reducers are manufactured in eight gear case sizes, nominal gear ratios are five:1, 13: one and 20: 1, A very wide choice of final driven speeds might be determined from the use of an acceptable input Wedge Belt Drive.
The units will generally be oil lubricated, nevertheless they are equally appropriate for prolonged daily life synthetic lubricants.
Identify the output speed from the gear units, multiply the absorbed energy (or Motor electrical power if absorbed electrical power nit known) by the service issue chosen in stage one.
Note: Gear units are momentarily capable of transmitting twice (2X) the rated capacity on start or all through operation.
Unit choice
The decision of single or double reduction gearbox is going to be established through the output pace needed . The typical operating speeds for each from the gearboxes could possibly be observed while in the electrical power rating and belt drive tables.
