Introducing the New Model HP The Textron Power Transmission Drive Advantage
Double Enveloping Worm Gear Reducer The element that distinguishes Textron Power Transmission
Textron Power Transmission introduces the Model HP reducers products from all the others is the double enveloping design. The

• Accuracy

• Minimum Backlash

Measuring Backlash: • Smooth Motion

Backlash is measured at the pitchline of the gear by rotating
the output shaft while holding the input shaft stationary. Application Assistance:

 PRODUCT SAFETY
0209

IMPORTANT
Product Safety Information
General - The following information is important in ensuring safety. It must be brought to the attention of personnel involved in the selection of
power transmission equipment, those responsible for the design of the machinery in which it is to be incorporated and those involved in its
installation, use and maintenance.
Our power transmission equipment will operate safely provided it is selected, installed, used and maintained properly. As with any power
transmission equipment proper precautions must be taken as indicated in the following paragraphs, to ensure safety.
Potential Hazards - these are not necessarily listed in any order of severity as the degree of danger varies in individual circumstances. It is
important therefore that the list is studied in its entirety:-
1) Fire/Explosion
(a) Oil mists and vapour are generated within gear units. It is therefore dangerous to use naked lights in the proximity of gearbox openings,
due to the risk of fire or explosion.
(b) In the event of fire or serious overheating (over (over 570 oF (300 oC)), certain materials (rubber, plastics, etc.) may decompose and
produce fumes. Care should be taken to avoid exposure to the fumes, and the remains of burned or overheated plastic/rubber materials
should be handled with rubber gloves.
2) Guards - Rotating shafts and couplings must be guarded to eliminate the possibility of physical contact or entanglement of clothing. It
should be of rigid construction and firmly secured.
3) Noise - High speed gearboxes and gearbox driven machinery may produce noise levels which are damaging to the hearing with prolonged
exposure. Ear defenders should be provided for personnel in these circumstances. Reference should be made to state and federal
regulations for reducing exposure of employed persons to noise.
4) Lifting - Where provided (on larger units) only the lifting points or eyebolts must be used for lifting operations (see maintenance manual or
general arrangement drawing for lifting point positions). Failure to use the lifting points provided may result in personal injury and/or damage
to the product or surrounding equipment. Keep clear of raised equipment.
5) Lubricants and Lubrication
(a) Prolonged contact with lubricants can be detrimental to the skin. The manufacturer's instruction must be followed when handling
lubricants.
(b) The lubrication status of the equipment must be checked before commissioning. Read and carry out all instructions on the lubricant
plate and in the installation and maintenance literature. Heed all warning tags. Failure to do so could result in mechanical damage and
in extreme cases risk of injury to personnel.
6) Electrical Equipment - Observe hazard warnings on electrical equipment and isolate power before working on the gearbox or associated
equipment, in order to prevent the machinery being started.
7) Installation, Maintenance and Storage
(a) In the event that equipment is to be held in storage, for a period exceeding 6 months, prior to installation or commissioning, we must be
consulted regarding special preservation requirements. Unless otherwise agreed, equipment must be stored in a building protected from
extremes of temperature and humidity to prevent deterioration.
The rotating components (gears and shafts) must be turned a few revolutions once a month (to prevent bearings brinelling).
(b) External gearbox components may be supplied with preservative materials applied, in the form of a "waxed" tape overwrap or wax film
preservative. Gloves should be worn when removing these materials. The former can be removed manually, the latter using white spirit
as a solvent.
Preservatives applied to the internal parts of the gear units do not require removal prior to operation.
(c) Installation must be performed in accordance with the manufacturer's instructions and be undertaken by suitably qualified personnel.
(d) Before working on a gearbox or associated equipment, ensure that the load has been removed from the system to eliminate the
possibility of any movement of the machinery and isolate power supply. Where necessary, provide mechanical means to ensure the
machinery cannot move or rotate. Ensure removal of such devices after work is complete.
(e) Ensure the proper maintenance of gearboxes in operation. Use only the correct tools and our approved spare parts for repair and
maintenance. Consult the Maintenance Manual before dismantling or performing maintenance work.
8) Hot Surfaces and Lubricants
(a) During operation, gear units may become sufficiently hot to cause skin burns. Care must be taken to avoid accidental contact.

(b) After extended running the lubricant in gear units and lubrication systems may reach temperatures sufficient to cause burns. Allow
equipment to cool before servicing or performing adjustments.
9) Selection and Design
(a) Where gear units provide a backstop facility, ensure that back-up systems are provided if failure of the backstop device would endanger
personnel or result in damage.
(b) The driving and driven equipment must be correctly selected to ensure that the complete machinery installation will perform satisfactorily,
avoiding system critical speeds, system torsional vibration, etc.
(c) The equipment must not be operated in an environment or at speeds, powers, torques or with external loads beyond those for which it
was designed.
(d) As improvements in design are being made continually the contents of this catalog are not to be regarded as binding in detail, and
drawings and capacities are subject to alterations without notice.

The above guidance is based on the current state of knowledge and our best assessment of the potential hazards in the operation of the gear
units.
Any further information or clarification required may be obtained by contacting our Application Engineers.
