RH gearheads suit high reduction ratios
Right-angle gearhead offers a double technology advantage for all applications with high reduction ratios (i=12 or more) bringing far-reaching enhancements for machine building and automation.
TPK+ is a two-stage right-angle gearhead for servo applications featuring a robot flange according to ISO 9409 (without a pin) It is equipped on the output side with the alpha TP+ planetary gearhead introduced just last year

Planetary gearheads ease inertia matching
Economy planetary gearheads have ratios that make it easier to match inertias and to achieve optimized servomotor performance in the mid-level range of gearhead sizing.
Right-angle gearheads have hollow shafts
A low-backlash hypoid gearhead with a hollow-shaft, right angle design offers high torque and speed, gear ratios in a single stage, low noise, high efficiency and freedom from wear.
The focus of TPK+ is on power density, notably in the torque, the torsional stiffness and the torsional backlash.
This double technology advantage is the sum of the following components.
* An extremely precise, helical-toothed planetary gearhead stage is mounted at the TPK+ output.

Software simplifies gear reducer search
Cymex calculation software will help you find the optimal gear reducer making use of databases, in which all Alpha products and over 6000 motors of other manufacturers are stored.
Maintenance-free gear reducers are efficient
Maintenance-free gear reducers offer outstanding efficiency with low tortional backlash and have the option of adding an integrated geared pulley drive system for right-angle drive.
Optimized helical gearing not only assures the high power density, positioning accuracy and stiffness typical of planetary gearheads but also facilitates exceptionally smooth running.
* Thanks to the hypoid gearset at the input (up to i=10 in a single stage), there are now many applications in which a two-stage gearhead can take the place of a three-stage bevel-planetary gearhead.
Once again, unprecedented smooth running is guaranteed by the innovative hypoid teeth.
Added to this, TPK+ offers high continuous speeds and up to 200% more torque than bevel gearheads.
Like the other right-angle gearheads in the alpha family, TPK+ is integrated in cymex, our unique sizing software application.
cymex allows an almost infinite number of drive solutions with different geometries, powers, moments of inertia, etc to be identified with a few simple mouse clicks.
In addition to the gearhead selection process, cymex also optimizes the other drive train components, including the motor and the machine elements at the gearhead output.
The cymex 'motor library' currently has the largest database of motor manufacturers in the world.
* The benefits of TPK+ are listed at a glance.
Smaller sizes owing to the powerful planetary stage.
Improved end product quality.
Only a third of the weight of servo worm gearheads with similar torque.
Design work is simplified, e g, TPK+ can replace cam mechanisms or combinations of several gearhead stages/timing belts - the low torsional backlash of the integrated TP+ planetary stage plays a crucial role in making this possible.
Better value for money (compared to bevel-planetary gearheads) with a wide range of reduction ratios because only two gearhead stages are needed instead of three.
The superior torsional and tilting stiffness is reflected in the increased precision of dynamic processes and the resulting higher productivity.
Smooth running means higher travel speeds free from irritating vibrations.
As a full service supplier, alpha is excellently placed to identify new and better drive solutions: TPK+ can optionally be supplied with alpha's rack-and-pinion system.
With its high torsional stiffness, rugged design and optional binary reduction ratios, TPK+ offers unrivalled advantages for 'endless positioning' applications.
