The new TPK+ right-angle gearhead opens the door to far-reaching enhancements for numerous key applications in the machine building and automation industries.
The new TPK+ right-angle gearhead from Alpha Gear drives offers a double technology advantage for all applications with high reduction ratios (i=12 or more).
It opens the door to far-reaching enhancements for numerous key applications in the machine building and automation industries.
The 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.
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.
Optimised 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, Alpha's bespoke sising 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 optimises 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.
