Gear Reducer suits endless positioning applications.
October 12, 2006 -
Two-stage right-angle gearhead, TPK+, is equipped with alpha TP+ planetary gearhead on output side and features helical-toothed planetary gearhead stage mounted at TPK+ output. Hypoid gearset at input (up to i=10 in single stage) enables product to take place of 3-stage bevel-planetary gearhead. Offered with range of reduction ratios, gearhead offers smooth, vibration-free running with torsional and tilting stiffness that lend to precision of dynamic processes.

Alpha's TPK+ Dual Technology Gear Reducer
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. 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+ 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.
