H Series Helical Worm Universal Mount Gear Reducers
 

 

 Tramec Series  "H" helical worm gear speed reducers are an exciting new range of aluminum worm gear reducer and cast iron worm gear reducer for the TVT Group around the globe.  While directly interchangeable to the old fashioned NMRV, the  - H range is heat sink free (easier to clean, less opportunity to collect dirt), and paint free (corrosion resistance cast into alloy) and machined on six sides for precision universal mounting.  H types available in easy to service "coupling" style input, as well as single and double input shafts, and the H helical primary design is unique to Tramec and is known as a reliable, low cost, efficient, easy to use high ratio helical/worm gearbox....available quickly!!!  1 or many pieces.

  • Automated assembly machinery.
  • Servo, Step, AC and DC Gearmotors, and Gear Brake Motor configurations directly from TVT production.
  • Ideal for storage retrieval systems, and other material handling equipment requiring more gearbox for less money.
  • Packaging machinery where noise, leak free operation, and reliability 24/7 is desirable.
  • Medical device equipment, surgical beds, hand driven and motor driven, NC surgical beds.
  • Drive for linear actuators.
  • Lightweight & powerful winch drives.
  • Food processing machinery.
  • Solar tracking, solar panel positioning, high ratio drive systems.
  • Applications requiring small and large sdouble, and triple reduction worm gearing.
  • Machine builders seeking mechanical torque limiter integral (ITL) to gear drive.
H series is designed in a modular vacuum diecast gearcase, leak free, and machined on fully automated CNC machining centers to provide a product that is readily adaptable, quick to assemble, and very cost competitive via a design & manufacture advantage approach.   We can quickly assemble standard parts into a near infinite combination of input, output, ratio, and mounting configuration to suit your need exactly... and ship quickly one piece or many.   Creative solutions, such as double output flanges, double input flanges, one motor with two reducers in AC or DC gearmotors, with our without brakes, can be created quickly without high expense.

  • Housing: Vacuum diecast corrosion resistant alloy aluminum in sizes 40 to 75, Engineered cast iron sizes 90 to 130.
  • Shaft or Flanged Input style available for immediate assembly.
  • Outputs: Single or Double Shafts, Hollow, and torque limiter outputs with torque-arm, flange, and universal foot mounting.
  • Gears: Superclean & hard forged bronze over cast iron hub machined to high recess action profile.
  • Worms: Machined from solid steel bar (not roll formed), then case carborized, quench hardened, and ground.
  • Bearings: Precision Tapered Roller & Ball - ISO Grade Manufactured of 52100 Vacuum Degassed Steels.
  • Tested for Noise, backlash, fit, and finish. ISO 9002 production.
  • 531 to 16000 in-lbs output torque (T2N).
  • i = 30 to 400/1 in standard ratios... to 40,000/1 (see XX, KX, KK Series).
  • Reduced backlash and servo inputs available by request.
  • ITL (Integrated Mechanical Torque Limiter) optional.
