In its GERWAH product range, RINGFEDER POWER TRANSMISSION offers an ample portfolio of pluggable elastomere couplings for practically any case of application.
When it comes to absorbing vibrations and shocks in drives and guaranteeing a precise and smooth power transmission, the elastomere couplings from the GERWAH portfolio are the first choice. They boast excellent running performance and compensate radial, axial, and angular misalignments. Depending on their dimensions, the couplings are fit for transmitting torques of up to 2.400 newton metres. Thanks to their compact design and their electrically insulating qualities they can be used in a wide range of applications.
GERWAH couplings stand out thanks to their first-class selection of material. Depending on the frame size, hubs are either made of high-strength aluminium or steel. Only recently a new manufacturing line was brought into service which took the quality of the elastomere spiders to an unprecedented level. Customers can now choose among five standard degrees of hardness ranging from shore 80A to shore 64D. This allows them to optimize performance and adapt the couplings to their individual requirements in terms of torsional rigidity and vibration behaviour.
As many as seven different models are available catering to a wide range of possible applications. There are two compact miniature couplings specifically designed to be used in confined spaces or areas which are difficult to access. The element is connected to the shaft by means of radial set screws (production series GWE 5102) or by means of a clamping hub (production series GWE 5103).
The various hub variants guarantee maximum flexibility. The GWE 5107 has been equipped with an expanding clamp and a clamping hub which qualifies it to be used in hollow shafts. With regards to easy installation the GWE 5106 series with clamping hub in split hub design is the measure of all things. The equivalent self-aligning couplings from the GWE 5104 series are slotted once up to size 19 and twice from size 24 on.
On top of that, RINGFEDER POWER TRANSMISSION offers its customers the GWE 5112 with an outer conical tapered end. Thanks to its symmetric design, this coupling guarantees for perfect concentric running and is thus qualified for highest torques. The GWE 5103 series strikes a balance between a reduced total length and perfect vibration damping qualities and is available with a single-slotted clamping hub.
It goes without saying that when it comes to special applications which go beyond the standard portfolio the engineers at RINGFEDER POWER TRANSMISSION are glad to develop tailor-made special solutions and support their customers in word and deed whenever questions arise.
