摘要： A magnetic encoder capable of securing sufficient adhesive strength of a scale molded member, preventing occurrence of cracking, breakage, etc., of the molded member, and also manufacturing at a low cost with high productivity is provided.
The present invention is directed to a magnetic encoder equipped with an annular core 20 and an annular scale molded member 42 formed on one surface of the core 20 and constituted by a plastic magnetic material multipolarly magnetized in the circumferential direction thereof. In this encoder, a plurality of radial grooves 21 extended radially and opened in a radially inward direction of the core are formed on one surface of the core 20 so that the grooves are arranged in the circumferential direction, and a filled molded portion 42 constituted by a plastic magnetic material filled in the radial groove 21 is integrally formed with the scale molded member 40.摘要翻译： 提供能够确保标尺模制构件的足够的粘合强度，防止模制构件的龟裂，断裂等的发生，以及以低生产率低成本地制造的磁编码器。 本发明涉及一种磁性编码器，其配备有环形芯20和形成在芯体20的一个表面上并由在其圆周方向上多极磁化的塑料磁性材料构成的环形鳞片模制构件42。 在该编码器中，在芯体20的一个表面上沿径向向内延伸的多个径向槽21形成在圆周方向上布置的填充模制部分42和填充模制部分42 填充在径向槽21中的塑料磁性材料与标尺模制构件40一体地形成。

摘要： A magnetic encoder is provided which can prevent a magnetized member from being separated from a fixed member to which the magnetized member is fixed under a severe temperature environment.
The encoder includes a fixed member which is fixed to a rotating member and a magnetized member 15 which is attached to the fixed member. The magnetized member 15, which is molded by mixing a magnetic powder in a resin, is bonded to the fixed member with a silicone resin based adhesive, and a thickness of an adhesive layer of the silicone resin based adhesive is 50 µm or more and 100 µm or less. In addition, an adhesive surface 17 of the fixed member with the magnetized member 15 is worked to be roughened.摘要翻译： 提供了一种磁性编码器，其可以防止磁化构件在恶劣的温度环境下与被固定的构件固定的固定构件分离。 编码器包括固定到旋转构件的固定构件和附接到固定构件的磁化构件15。 通过将树脂中的磁性粉末混合而成型的磁化部件15用硅树脂系粘合剂粘接在固定部件上，硅树脂系粘合剂的粘接层的厚度为50μm以上100 μm以下。 此外，固定构件与磁化构件15的粘合表面17加工成粗糙化。

摘要： This invention provides a magnetic encoder that can satisfactorily ensure the adhesive strength of a scale molded product, can prevent the occurrence of cracking, fissuring or the like in the molded product, and further can be manufactured at low cost with high productivity. The magnetic encoder comprises an annular core metal (20) and an annular scale molded product (42) provided on one side of the core metal (20) and formed of a plastic magnetic material which has been multipolarly magnetized in the circumferential direction. In this encoder, a plurality of radially provided grooves (21) extended radially on one side of the core metal (20) and open to the internal diameter direction are circumferentially arranged, and a filling molded part (42) formed of a plastic magnetic material filled into the radially provided grooves (21) is provided integrally with a scale molded product (40).
