The hubs are linked by fitting keys, toothed shafts or interference fit assemblies with the work machines. The toothing of hubs is achieved by crowned toothing. The thickness of the teeth decreases with increasing tooth width. Thanks to the crowned toothing, the swivel range is implemented with a small tooth flank clearance. The combination of small tooth flank clearance and centering in the toothing allows a smooth running over the entire speed and torque range.<br \/>\nThe couplings in a double cardanic design (two hinge planes) are able to compensate radial, angular and axial shaft displacements. The grease lubrication ensures a low maintenance effort and a long durability. O-rings or double lip seals are inserted to seal the coupling space filled with grease.<\/p>\n<p>Kupplungswerk Dresden has many years of experience in the sector of development and manufacturing of special gear couplings for many different applications.<\/p>\n<p>Models:<br \/>\nmodel A: standard design;<br \/>\nmodel B: design for holding disc;<br \/>\nmodel C: design axial clearance limited;<br \/>\nmodel S: design with centrally located brake disc;<br \/>\nmodel H: design with spacer;<br \/>\nmodel U: design with undivided sleeve.<\/p>\n<p>&nbsp;<\/p>\n","protected":false},"featured_media":1036,"template":"","meta":{"inline_featured_image":false,"_vp_format_video_url":"","_vp_image_focal_point":[]},"class_list":{"0":"post-632","1":"product","2":"type-product","3":"status-publish","4":"has-post-thumbnail","6":"product_cat-mufty-kwd","7":"product_cat-mufty","9":"first","10":"instock","11":"shipping-taxable","12":"product-type-simple"},"acf":[],"aioseo_notices":[],"_links":{"self":[{"href":"https:\/\/vlakita.com\/en\/wp-json\/wp\/v2\/product\/632"}],"collection":[{"href":"https:\/\/vlakita.com\/en\/wp-json\/wp\/v2\/product"}],"about":[{"href":"https:\/\/vlakita.com\/en\/wp-json\/wp\/v2\/types\/product"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/vlakita.com\/en\/wp-json\/wp\/v2\/media\/1036"}],"wp:attachment":[{"href":"https:\/\/vlakita.com\/en\/wp-json\/wp\/v2\/media?parent=632"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
