Brake lining seat and spinning rotor assembly

The utility model relates to a brake lining seat and a spinning rotor assembly. The brake lining seat is used for mounting the brake lining to a rotor brake unit of a spinning rotor assembly. The spinning rotor assembly is used for the rotor spinning machine. In order to provide a brake lining seat and a rotor brake unit of a spinning rotor assembly, which can be reliably operated in order to particularly prevent a user operating a rotor spinning machine from being injured and can quickly and reliably reduce the speed of a spinning rotor shaft, the brake lining seat has a fastening region for mounting the brake lining seat to the rotor brake unit, a mounting region for mounting the brake lining to the brake lining seat, wherein a surface of the mounting region for supporting the brake lining is curved. 本实用新型涉及一种制动衬片座和纺纱转杯组件。制动衬片座用于将制动衬片安装至纺纱转杯组件的转杯制动单元。纺纱转杯组件用于转杯纺纱机。为了提出能可靠操作以便尤其避免操作转杯纺纱机的使用者受伤且能够快速可靠地减速纺纱转杯轴的制动衬片座以及纺纱转杯组件的转杯制动单元，该制动衬片座具有：用于将该制动衬片座安装至该转杯制动单元的紧固区，用于将该制动衬片安装至该制动衬片座的安装区，其中该安装区的用于支承该制动衬片的表面是弯曲的。
