SMR Gearbox Installation
Satisfactory performance is dependent upon proper installation. lubrication and upkeep. consequently it is vital that the directions during the set up and upkeep leaflet. supplied with just about every gearbox. are followed meticulously. some of the critical aspects of belt and torque-arm installation are listed below.
1. Install pulley on gearbox input shaft as near on the reducer possible, and mount reducer on driven shaft as close to bearing as sensible. failure to perform this may cause excess loads from the input shaft bearings and output bearings and could cause their premature failure.
2. Install motor and wedge belt drive using the belt pull at approximately 90° on the center line concerning driven and input shafts. this will likely allow tensioning of your wedge belt drive with all the torque arm which need to ideally be in tension. if output hub runs anti-clockwise. torque arm must be positioned the best.
three. lnstall torque-arm fulcrum on the rigid help to ensure the torque-arm will probably be at around proper angles to the center line with the driven shaft plus the torque arm case bolt. ensure that there may be sufficient take up from the turnbuckle for belt stress adjustment.
Retain near.
Bell drive may very well be situated in any hassle-free postion. should the torque arm is usually to be made use of to tighten the belts, the drive must be at about tight angle on the line in between the input and output shafts.
Bell drive can be found to your right if desired.
If output hub rotates clock-wise. place belt drive and torque arm in opposite course to that shown within the illustration.
Torque arm and belt take up.
Torque arm could be mounted on the right if preferred.

the best way to order 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 2 flange mount
Eighth digit: indicates output hub bore needed: one standard metric bore. two different metric bore.
Example
Size e unit twenty:1 nominal gear ratio, shaft mounted with regular metric hub bore (55mm): SMR-E2001
It backstop are essential, these really should be order separately. and should specify the output hub rotation. E.g.: SMR-E2001 finish 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 in which it is essential to prevent reversal of rotation. it’s promptly installed inside the reducer, by merely getting rid of a cover plate
Note: For ratio five: 1 gear box, backstop usually do not proposed.
Flange mounting
SMR situation layout is this kind of that the reducer might be bolted direct to supporting framework. this flange mounting utilization of the reducer may well allow designers to omit a bearing or pillow block, however it does. obviously. do away with the quick belt adjustment function characteristic of shaft mount.
Note: Conventional SMR gearbox never drill mount screws. when customer have to have these types mount, please specify from the buy.
