The invention relates to a speed reducer, a hydraulic motor, a construction machine and a manufacturing method of the speed reducer. The speed reducer is provided with a planetary gear type speed reduction part and an end cover part. The planetary gear-type speed reduction unit has a sun gear to which driving force is input, and a planetary gear that meshes with the sun gear. The end cover part is disposed so as to face an axial end face of the sun gear of the planetary gear-type speed reduction part. At least one of a cover end surface of the end cover section facing the end surface of the sun gear and the end surface of the sun gear has a surface-hardened section in which the surface of the portion in contact with each other is hardened.
本发明涉及减速器、液压马达、施工机械以及减速器的制造方法。本发明的减速器具有行星齿轮式减速部和端部盖部。行星齿轮式减速部具有被输入驱动力的太阳齿轮和与太阳齿轮啮合的行星齿轮。端部盖部配置为与行星齿轮式减速部的太阳齿轮的轴向上的端面相对。端部盖部的与太阳齿轮的端面相对的盖端面和太阳齿轮的端面中的至少任一者具有对彼此接触的部位的表面实施了硬化处理的表面硬化处理部。
