Abstract

a rack comprising a rigid base which accepts the forces generated by a passing mobile drive, where the base has a continuous elastic strip stuck along the track and which also accepts the drive loads. Pref. the track is a rack and pinion system and the elastic strip is a layer of rubber of varying thickness laid over the rack tooth profile. The bodies of the teeth may be relieved as pockets filled with sand, concrete fibres, polyurethane resins or similar materials. Pref. the pinion also transmits its stresses via a layer of elastic material. Pref. the layer of elastic material is a synthetic rubber such as neoprene, "perbunan", "viton" or a silicone rubber. Pref. the rubber is itself covered with a hard flexible coating having a low coeff. of friction w.r.t. the material used for the teeth of the pinion. Esp. suitable for inclined rail systems on hillsides or for pairs of racks mounted on each side of a track for a vehicle moving on pneumatic cushions. The rubber layers accommodate slight mismatching between the engaging tooth systems, increase the maximum couple possible by allowing deformation of the contact area, and suppress noise. The filler is used to reduce weight and cost, and also help reduce noise.
