Servo gears: AP / HP servo gears

Product catalog summary

Overview
ESR Pollmeier GmbH specializes in planetary and hybrid gears for ESR servo motors, offering reduction ratios from 4:1 to 100:1 and rated output torque up to 200 Nm. The AP and HP series include one-stage and two-stage planetary gears with low torsional backlash and high torsional rigidity, as well as hybrid gears combining precision planetary gears with preceding spur gears.

Product and Service Offerings
ESR provides complete drive packages that include servo amplifiers, motors, position sensors, gearboxes, and brakes, along with power supply units, connectors, cables, and software. These components are designed to work seamlessly together, ensuring smooth installation and reliable operation. ESR also offers consulting services to help customers select the appropriate servo drive for their applications.

Applications
The gears are suitable for high dynamics and accuracy in various applications, including handling and assembly systems, optical disc production, packaging, textile, plastics processing, coiling, flame cutting, measuring and testing, and electronics production machinery.

Characteristics of AP and HP Servo Gears
Design: The gears are available as planetary or hybrid gears, with one-stage reductions from 4:1 to 10:1 and two-stage up to 100:1. They can be adapted to various applications due to different output shafts and flange designs.
Planetary Gears (AP): These gears offer low torsional backlash and high torsional rigidity, with output torques ranging from 32 to 1500 Nm.
Hybrid Gears (HP): Combining planetary and spur gears, these offer high output torque and power density, with output torques from 15 to 360 Nm.

Additional Features
AP and HP gears feature fixed planetary output gears with exchangeable spur gear modules, allowing for on-site adaptation. The design includes separate lubrication for input and output bearings, enabling flexible installation. The gears also have a finned die-cast box for effective heat dissipation.

Motor Mounting and Output Shaft Options
The gears are mounted to motors by ESR personnel, with two flange designs available for each frame size. Standard shafts are without keyway, but options with keyway and thread are available. Angular or belt-driven back gears can be connected if required.

Performance Specifications
The document includes detailed performance specifications, including permissible shaft load, rated lifetime of output bearings, and average output speed. It also provides information on how to order, including options for housing, output shaft, motor interface, and reducer type.

Catalog excerpts

Servo gears of the AP and HP series: one-stage and two-stage planetary gears with low torsionalbacklash and high torsional rigidity, or hybrid gears, comprising a precision planetary gear and a preceding spur gear. > ESR drive packages consist of servo ampli- fiers, servo motors, position sensors, gear boxes, and brakes. They are supplemented by power supply units, connectors, cables (ready- assembled on request), and software. All parts of the package are matched and have been tested as combinations. The delivery of the complete drive system from a single source guarantees smooth installation, reliable opera- tion, and definite system responsibility on the part of one single supplier.Our service offer includes individual drive sys-tem determination.

General The servo gears described here are available in two series as planetary gears orhybrid gears. With one-stage reduction from 4 : 1 to 10 : 1, two-stage up to100 : 1, and options like different output shafts they can be adapted to various applications. AP and HP servo gears can be used in combination with virtually allESR servo motors because of oblong holes in the motor mounting flange each gear frame size is available with two flange designs. Design In the main units of the AP and HP servo gears evolvent gear wheels provide thereduction and the power transmission. Optimally arranged as...

Further advantages Fixed planetary output gear, combined with an exchangeable spur gearmodule, for reductions from 4 : 1 to 90 : 1 in a housing of the same size. Adaptation can be carried out on-site! Spur gear module made of one piece of casting, inner contours adapted to thespur gear wheels and machined while clamped, for exact parallel axes, optimal lubricant dispersion, and smooth run with less wear and tear. Input and output bearing lubricated separately, so the gear can be installed inany way desired. Finned die-cast box with large surface area provides for good heat dissipation,resulting...
