Abstract
Different belt tensioning rollers (1) are produced according to a universal concept in that different belt tensioning roller (1) main parts (2), each of which has at least one reinforcing element (9, 14, 15) and each of which can be combined with a rolling bearing (10), are additively manufactured on the basis of a uniform roller basic design (GF) by making different modifications to the roller basic design (GF).
Claims20
A method for producing belt tensioning rollers, wherein, on the basis of a uniform basic roller shape, different main bodies of belt tensioning rollers, which each have at least one reinforcement, are produced generatively by various modifications of the basic roller shape.
A method for producing a set of belt tensioning rollers comprising:
- providing a powder material;
- generatively forming a plurality of main bodies of the set of belt tensioning rollers with the powder material, wherein a respective main body is formed to include one or more reinforcement webs, at least two cavities, and a depowdering opening, wherein the depowdering open is configured for removal of the powder material following formation of the respective main body.
A belt tensioning device comprising:
- one or more belt tensioning rollers, wherein a respective belt tensioning roller comprises a main body and includes a reinforcement, wherein the main body is configured to receive a rolling bearing held in an inner wall of the main body, wherein the main body has two cavities including an outer cavity defined by a belt support wall and an inner cavity defined by the inner wall, wherein the main body includes an opening for removal of powder used to form the main body.
