摘要： An electrically driven power transmission system box assembly positioned by stepped pins (5) and the installation method thereof are disclosed. The box assembly comprises: a housing and shaft string assembly (4), several stepped pins (5), a first housing (3), and a first bearing. The housing and shaft string assembly (4) comprises a housing and a shaft string (9) supported on the housing. The stepped pin (5) comprises an engagement section and a guide section, a diameter of the engagement section is greater than a diameter of the guide section, and an end part of the engagement section is fixed in a fixing pin hole of the housing. The first housing (3) is installed and fixed to the housing and shaft string assembly (4) under the guidance of the guide section. The rear end of the shaft string (9) is supported on the first housing (3) via the first bearing. This technical solution utilizes the larger radial gap between the guide section of the stepped pin (5) and the positioning pin hole to prevent surface scratches on the raceway of the first bearing caused by the compression between the inner ring and rollers of the first bearing (7) during the assembly process of the shaft string (9) and the first housing (3), thereby improving the service life of the bearing and the entire system.

摘要： An electromagnetic clutch is disclosed. The electromagnetic clutch comprises a fixed component, a driven component and an elastic component (1). The fixed component comprises a magnetic yoke (2), the magnetic yoke (2) is provided thereon with multiple iron cores (3), and each iron core (3) is provided thereon with a coil (4). The driven component comprises an armature disc, and the armature disc is provided thereon with multiple magnets (6). The armature disc and the magnetic yoke (2) are disposed correspondingly, and the iron cores (3) and the magnets (6) are disposed correspondingly. The elastic component (1) is used to keep the armature disc at a disengaged position from magnetic yoke (2). When the coil (4) is energized in a forward direction, the iron core (3) attracts the magnet (6), and the armature disc overcomes an elastic force of the elastic component (1) and moves to an engaged position with the magnetic yoke (2), so that the fixed component and the driven component are connected for transmission. When the coil (4) is energized in a reverse direction, the iron core (3) generates an electromagnetic force to reduce an attractive force of the magnet (6), the elastic force of the elastic component (1) overcomes the attractive force of the magnet (6), and repels the armature disc to a disengaged position from the magnetic yoke (2).

摘要： The present disclosure discloses a stator punching piece, stator core and motor. The stator punching piece is formed by die stamping. An outer circumference of the stator punching piece is provided with a continuous concave-convex structure extending in an axial direction of the stator punching piece for a cooling medium to flow therethrough, so as to increase an heat dissipation area of an outer circumference of a stator core composed of the stator punching pieces and improve a flow state of the cooling medium on the outer circumferential surface of the stator core, thereby increasing a rated power and rated torque of a motor. Since the stator punching piece is formed by die stamping, changing the shape of the outer edge of the stator punching piece has no effect on the manufacturing cost of the motor. Without increasing the cost, the rated power and rated torque of the motor can be increased by 5-10%.
