The invention relates to a permanent-magnet offset radial magnetic bearing. It includes radial stator, control coil, circle permanent magnet, exterior magnetic pole iron core and rotator covered by rotator iron core. The permanent-magnet offset radial magnetic bearing has advantage of simple structure, small volume, and light weight. It has a broad application prospect in kinds of magnetic suspension systems that take up small space on radial direction.

The invention relates to a motor, in particular to a permanent-magnet synchronous traction motor for a motor train. The permanent-magnet synchronous traction motor for the motor train solves the problem that an existing permanent-magnet synchronous motor is not suitable for being directly used as a permanent-magnet synchronous traction motor for a motor train due to structure defects. The motor adopts a novel rotor magnetic circuit structure punching plate, a high-integration compact type rotor structure, a detachable connecting box structure and a lead structure. A connecting box can be conveniently disassembled so that the motor can be installed easily. A U-shaped magnetic circuit permanent magnet structure of an inner rotor is adopted, the magnetic separation bridge and circular bead design is added, and therefore the start and overload capacity of the motor can be improved. A rotor pressing ring at the driving end integrates rotor core pressing, permanent magnet end face pressing, rotor dynamic balancing and an inner seal ring labyrinth seal structure into a whole, the advantages that the structure is compact, the axial occupied space is small, and the installation is convenient are achieved, and the motor can be widely applied in the field of locomotive trains. According to the research, development and the operation of the permanent-magnet synchronous traction motor for the motor train, realistic bases are supplied for the permanent-magnet motor to research and develop a permanent-magnet traction motor structure with higher power, higher rotation speed and higher power density.

The invention provides a connector. The connector comprises an elastic body unit with two members to be connected, wherein the members to be connected each comprise a star-shaped part with a star-shaped part arm, the two star-shaped parts are arranged oppositely and axially arranged in a staggered mode so that a plurality of containing spaces are formed between the star-shaped part arms. Elastic bodies are arranged in the containing spaces. The connector is simple and compact in structure and small in axial occupied space.

The invention provides a connector comprising an elastomer unit having two pieces to be connected. Wherein, the pieces to be connected respectively have a connecting arm, and the two connecting arms are arranged opposite to each other and staggered from each other along the axial direction. The end region of the connecting arm is connected to the elastic ring. The connector provided by the invention has a compact structure and occupies little space in the axial direction.

The invention relates to a washing machine deceleration clutch and a washing machine. The deceleration clutch comprises an input shaft, a deceleration device, a clutch device, an output shaft and an output shaft sleeve, wherein the clutch device is at least partially arranged on the periphery of the deceleration device; the clutch device at least comprises a clutch shaft sleeve capable of axially moving and a driving device driving the clutch shaft sleeve to axially move; the clutch shaft sleeve is arranged outside an annular gear of the deceleration device and is in a connection with the annular gear in way of being capable of sliding relative to the annular gear but incapable of rotating relative to the same; the driving device drives the clutch shaft sleeve to axially move to control different output states of the output shaft and the output shaft sleeve; the driving device comprises at least one clutch press plate coaxially arranged with the clutch shaft sleeve; and the clutch press plate can circumferentially rotate to drive the clutch shaft sleeve to axially move. The deceleration clutch is simply structured and axially occupies small space; and overall height of the deceleration height can be reduced and washing capacity can be increased.
