The PGR PHC/PBC series belongs to PGR's helical cycloidal gearboxes, combining a cycloidal input stage with helical and bevel output housings. Unlike conventional gear units, motion is transmitted by drive elements rolling over each other rather than by gear teeth sliding against each other. This meets the demand for efficiency even at high ratios, compact size, economy and product reliability.
The series covers 0.2–75 kW, 7–60332 Nm and ratios of 6–658503. Low noise, easy installation, overload capacity, no thermal factor limitation and a long service life are among its main advantages. Input options include a motor connection with PAM adapter, a C-Face coupling and a W free input shaft. The cycloidal kit in the input stage is lubricated independently of the main housing: up to size 611 with grease in all mounting positions, and from size 614 upwards with oil or grease depending on the mounting position.
PHC and PBC gearboxes come with a hollow output shaft as standard; plug-in, solid and shrink disc output shafts, flanges, torque arms and platforms are available on request. PHC output housings are GG25 grey cast iron and PBC output housings GG40 ductile iron.
Features
Rolling power transmission
Drive elements roll over each other to transmit motion, instead of the sliding contact found in conventional gearing.
High efficiency at high ratios
Runs efficiently across a ratio range of 6–658503, even at high ratios.
Low noise, overload capacity
Combines low noise and overload capacity with a compact size.
No thermal limitation
No thermal factor limitation and a long service life are key reasons to choose the series.
Independently lubricated cycloidal kit
The cycloidal kit in the input stage is lubricated separately from the main housing and is easy to assemble.
Wide choice of outputs
Hollow shaft as standard; plug-in, solid or shrink disc shafts, flanges, torque arms and platforms on request.
