servo worm reducer

EP offers a full range of modular servo gearboxes /worm reducers. The modular design permits configurations with motor source flange and end result pinion for rack and pinion drives, along with solid output shafts, Hollow bore output, and suggestions shafts for all the positioning applications. The modular style allows for universal mounting of the gearbox in any orientation.
Servo-Worm Reducers were specifically developed for use with the latest servo motors found in applications that demand specific positioning and repeatability.
These reducers are suitable for applications in material handling, automation, equipment tool, and robotics.

High-Torque (HT) Servo-Worm Reducers
This standard range of Servo-Worm Reducers are simply perfect for use in applications that demand high precise positioning, performance and repeatability. They were especially developed for make use of with state-of-the-art servo engine technology, providing restricted integration of the motor to the machine. Angular backlash of less than 1 arc-moments is provided standard.
They are available in four sizes (50 mm to 100 mm center distance) with input speeds up to 5,000 rpm, reduction ratios from 4.75 to 52:1 and output torque capacities up to 885 lb.ft. A wide range of motor couplings and mounting flanges are available for assembly to almost all servo motors, and the hollow bore result can be utilised to mount result shafts, pinion shafts, or other drive elements.
Standard applications for these reducers include precision rotary axis drives, traveling gantries & columns, material handling axis drives, zero-backlash axis drives and electronic line shafting. Industries dished up include Material H, ling, Aerospace, Automation, Machine Device and Robotics.
Gearing: Internal gear style was optimized to provide an angular backlash of less than 1 arc-minutes at assembly, with the choice of “in the discipline” adjustable backlash in the event necessary.
Bearings: Input angular get in touch with bearings for high source speed, and robust output tapered-roller bearings for superior radial and axial load capacity.
Housing: Light weight aluminum housing for good heat dissipation, with essential source flange for servo motors and universal mounting on any face.
Output: The result bore is available with a good compression-type hub or a ISO 9409-1 flange (see dimension webpages). We give a line of add-ons to adapt these outputs to direct shafting, Rack & Pinions, or other gearing types.
This gearbox utilizes a 30:1 ratio worm-travel reduction for applications that want extremely slow and smooth rotational motion. The worm-drive design not merely minimizes backlash but likewise eliminates back-generating the gearmotor so a position can be held even when power is not applied. The precision ground 3/8” stainless steel result shaft is supported by dual 3/8” ABEC 5 ball bearings to aid lots from any orientation. The ¼” ABS plastic and lightweight aluminum structure offers a rigid framework without adding unnecessary weight and is very easily mounted to any flat work surface by utilizing the bottom mounting tabs. Our Common Spur Gear motors will continue to work with this gearbox (engine distributed separately). The Vertical Shaft Worm-Drive Gearbox is simply perfect for turn-tables, time-lapse systems and low-rate applications that want high precision and torque.
Motor RPM required = 1 / (minutes per rotation desired / 30)
Example: 1 / (ten minutes per rotation / 30) = 3 RPM motor needed to achieve 10 minutes per rotation (in max speed)
now offers an economical right position gearhead for make use of with small NEMA 23 through 56 and similar little metric servo and stepper motors. These reducers happen to be most appropriate for basic action and suggestions speeds of 2000 rpm where profile request costs certainly are a major consideration.

Worm Gears are best angle drives providing huge swiftness ratios on comparatively short center distances from 1/4” to 11”. When correctly installed and lubricated they function as quietist and smoothest jogging type of gearing. Because of the high ratios practical with worm gearing, optimum speed reduction could be accomplished in much less space than many other types of gearing. Worm and worm gears are powered by nonintersecting shafts at 90° angles.
EFFICIENCY of worm gear drives depends to a sizable level on the helix angle of the worm. Multiple thread worms and gears with higher helix angle prove 25% to 50% better than single thread worms. The mesh or engagement of worms with worm gears creates a sliding action creating considerable friction and greater loss of efficiency beyond other types of gearing. The use of hardened and floor worm swith bronze worm gears rises efficiency.
LUBRICATION is an essential factor to boost efficiency in worm gearing. Worm equipment action generates considerable heat, decreasing efficiency. The volume of electric power transmitted at confirmed temperature raises as the efficiency of the gearing raises. Proper lubrication enhances effectiveness by reducing friction and heat.
RATIOS of worm equipment sets are dependant on dividing the number of teeth in the gear by the number of threads. Thus one threads yield bigger ratios than multiple threads. All EP. worm equipment sets are available with either left or right hand threads. EP. worm gear sets can be found with Triple, Qua, Double and Single-druple Threads.
Protection PROVISION: Worm gearing shouldn’t be used as a good locking mechanism to carry heavy weights where reversing actions can cause harm or injury. In applications where potential injury is non-existent and self-locking is preferred against backward rotation then use of a single thread worm with a minimal helix angle quickly locks the worm gear travel against backward rotation.
Materials recommended for worms is usually hardened steel and bronze for worm gears. On the other hand, depending on the application unhardened metal worms operate adequately and more economically with cast iron worm gears at 50% horsepower ratings. In addition to steel and hardenedsteel, worms are available in aluminium, stainless, bronze and nylon; worm gears can be found in steel, hardened metal, stainless, metal, nylon and non-metallic (phenolic).
EP also sells equipment tooth measuring gadgets called GEAR GAGES! Gear Gages decrease mistakes, save time and money when identifying and purchasing gears. These pitch templates are available in nine sets to identify all the standard pitch sizes: Diametral Pitch “DP”, Circular Pitch “CP”, Exterior Involute Splines, Metric Module “MOD”, Stub Tooth, Fine Pitches, Coarse Pitches and Uncommon Pitches. Refer to the section on GEAR GAGES for catalog figures when ordering.
