1 1.7 Travel wheel materials EN-GJS-700-2 (GGG 70) Travel wheels with Hydropur tyre Polyamide Application of the various travel wheel types GJS-700-2 (GGG 70) is a spheroidal graphite cast iron, a material with a self-lubricating effect owing to the graphite incorporated in it. This means that the wheels feature high resistance to wear for a low travel resistance, with rail wear also being reduced to a minimum. The high inherent damping effect of the travel wheels guarantees good running characteristics for the travel unit. Travel wheels which perform a guide function, e.g. flange-guided, with a minimum gap between the edge of the tread and the travel wheel rail of 1 mm and a guide roller assembly with the same distance are available. If extreme wear is expected, e.g. casting sand or similar, the travel wheel tread surface or guide flange can be hardened to 56 ± 2 HRc for slipfree operation. This hardening is only to reduce wear. Hydropur is a polyurethane elastomer which features good resistance to hydrolyses compared to other conventional polyurethanes (such as Vulkollan, for example). This material features significantly higher friction values compared to GJS (GGG) wheels, thus making travel wheels with a Hydropur tyre predestined for highly dynamic applications. Running noises are reduced to a minimum owing to the good dampening characteristics. Attention must be paid to the considerably reduced permissible load capacities compared to wheels of GJS-700-2 (GGG 70). Wheels with Hydropur tyres are particularly suitable for operation on concrete surfaces owing to the low contact area pressure or in the case of particularly high acceleration rates of up to 1,5 m/s 2 for friction drives due to the high friction coefficient between the travel wheel tyre and counterpart material. This material can be used at up to 100 ºC for high temperature applications. Compared to GJS-700-2 (GGG 70) travel wheels, travel wheels made of polyamide (PA 6 casting) feature significantly reduced travel noise for comparable friction values. Attention must also be paid to the significantly reduced permissible load capacity compared to travel wheels made of GJS-700-2 (GGG 70). Owing to the high specific contact pressure as a result of the round shape, polyamide is only suitable for operation on steel materials or similar. Properties Spheroidal graphite cast iron Hydropur Polyamide Stainless High acceleration with friction connection above 0,5 m/s2 O O O High acceleration as positive connection above 0,5 m/s2 H igh pressure: wheel/rail C ounterpart material: steel Counterpart material: aluminium O O C ounterpart material: concrete C ounterpart material: screed Counterpart material: wood O Temperature up to 100 ºC ( 112 to ) O O O O High humidity at high temperatures O O O O utdoor operation with ice and snow O O suitable partially suitable not suitable 20521b.p65/0107 Travel wheels with hardened treads For operating conditions in which increased travel wheel wear is likely (e.g. rails with extreme dirt accumulation), the running surfaces and flanges of the spheroidal graphite cast iron travel wheels can be hardened (to a depth of 2 to mm). For this to be possible, travel wheel s 112 must not feature any flange wear indicators. Hardening is then to 56 ± 2 HRc. 19
1 1.8 Paint finish Standard 112 The aluminium wheel block housings are provided with a weather-resistant powder coating in RAL 7001 (silver grey) with a minimum thickness of 90 µm before leaving the factory. A uniform coating quality is ensured by a works standard oriented to meet wheel block housing requirements (ident no. 012 26 99). 0 Primer coat: Single coat of silver grey paint, coat thickness approx. µm Finish coat: Silver grey RAL 7001, % shine, approx. µm Special paint finish 112 For special paint finishes, wheel blocks can be supplied with a dual component PUR finish coat at the request of the customer. If the paint finish is to be applied by the customer, attention must be paid to works standard for special paint finish on powder-coated wheel block surfaces (ident no. 012 28 99). 0 For non-standard RAL colours, a corresponding finish coat may be applied to wheel blocks at the request of the customer. Special paint finishes on request. Acid-resistant paint finish 112 The surfaces of wheel blocks with a powder-coated finish may be used in environments with acid vapours without any treatment. Alternatively, a dual component acid protection paint finish may be applied to appropriately pre-treated housings. Wheel blocks must also be fitted with ball bearings featuring double lip seals. The gap between the housing and the cover is seated with an acid-proof varnish. 0 Wheel blocks can be supplied with an acid protection paint finish for applications in environments with acid vapours. 20 20521b.p65/0107
