Abstract

The invention relates to the field of hub motor sealing and discloses a sealing member for use between the stator and the rotor of a motor and a hub motor. The sealing member (1) is used for line sealing, surface sealing, or multi-lip sealing a portion. The sealing member (1) comprises an annular support body (2). A first sealing lip (3) and a second sealing lip (4) are integrally formed on the support body (2). The first sealing lip (3), the second sealing lip (4) and the support body define a storage opening (5). The inside or outside of the support body (2), the inside or outside of the first sealing lip, or the inside or outside of the second sealing lip is provided with a metal skeleton (6) for improving the assembly strength of the sealing member (1). The sealing member can achieve reliable sealing and automatic compensation.

Description

technical field

[0001] The invention relates to the field of hub motor seals, in particular to a seal used between a motor stator and a rotor and a hub motor. Background technique

[0002] Chinese invention patent CN102007676B discloses an outer rotor type motor and an outer rotor type in-wheel motor. It discloses a technical solution as follows: the outer rotor type motor includes: a stator module formed in a cylindrical shape with a closed rear end, the stator The module is installed on the shaft passing through the central part of the rear end of the stator module; the stator is fixedly installed on the outer circumferential surface of the stator module; the main cooling part is arranged inside the stator module On the peripheral surface, in order to reduce the temperature of the corresponding part, the main cooling part includes one or more recessed grooves formed along the inner peripheral surface of the stator module, and the grooves are formed in a plurality of axial ...
