Abstract

The invention discloses a brake rotor fixing mechanism and an installation method thereof. The mechanism comprises a stator fixed to an end cover of a motor through a bolt, and a rotor connected with a motor shaft in an integrally formed mode, wherein the stator and the rotor are coaxially installed, the rotor is located on the outer side of the stator, an axial gap is reserved between the stator and the rotor, the rotor comprises an armature, a leaf spring, a flange and a fastening ring, the armature is located on the outer side of the stator, the leaf spring is arranged between the outer side of the armature and the inner side of the flange, a flange boss on the outer side of the flange is connected with the motor shaft in a sleeving mode, an open groove is formed in the flange boss, and the fastening ring is connected to the flange boss in a sleeving mode to squeeze and deform the flange boss so as to clamp the motor shaft. According to the brake rotor fixing mechanism and the installation method thereof, axial movement is avoided, structure is simple, installation is easy, reliability is high, cost is low, the mechanism can be used under positive and negative impact and in a high-vibration environment, and application prospects are broad.

Description

technical field [0001] The invention relates to the technical field of brake fixing, in particular to a brake rotor fixing mechanism and an installation method thereof. Background technique [0002] At present, the fixing method of the motor shaft and the brake is mainly a jackscrew plus a keyway structure, such as figure 1 As shown, the structure of the brake includes a stator 101, a rotor 102, an air gap 103, an armature 104, a spring leaf 105, a flange 106, a top screw 107, and a keyway 108. The motor shaft and the brake are matched through the top screw 107 and the keyway 108. Fixed, this conventional fixed structure has low reliability and is not suitable for positive and negative impact and high vibration environments, and there is a risk of axial movement, low reliability, not suitable for positive and negative impact and high vibration environments, and , it is necessary to process the keyway structure, increase the processing and installation process, and the cost ...
