Embodiment Construction

[0009] In order to further understand the invention content, characteristics and effects of the present invention, the following examples are given, and detailed descriptions are as follows in conjunction with the accompanying drawings:

[0010] see figure 1 , a one-way braking electromagnetic safety brake, including a shaft sleeve 6 that rotates with the motor shaft 7, the shaft sleeve 6 is supported on the motor shaft 7 through a one-way bearing 9 and a support bearing 8, and a card is opened on the shaft sleeve 6 The ring groove is used to install the collar to fix the bearing. The inner and outer sides of the shaft sleeve 6 are equipped with friction discs 10, and the inner side of the shaft sleeve 6 is equipped with a flange 12 fixedly connected to the rear end surface of the motor 1. The armature 11 and the end cover 2 are installed in sequence to the outside. The armature 11 is looped on the sleeve 6 and is adjacent to the friction disc 10 on the outer surface of the sl...

Abstract

The invention discloses a unidirectionally-braking electromagnetic safety brake comprising a shaft sleeve, wherein the shaft sleeve rotates along with a motor shaft. The shaft sleeve is supported on the motor shaft through a one-way bearing and a supporting bearing, friction discs are arranged on an inner side surface and an outer side surface of the shaft sleeve, a flange is arranged on the inner side of the shaft sleeve and is fixedly connected with the back end face of a motor, an armature and an end cover are sequentially arranged on the outer side of the shaft sleeve from inside to outside, the armature is movably sleeved on the shaft sleeve and is adjacent to a friction discs on the outer side surface of the shaft sleeve, the end cover is internally provided with an electromagnet and a spring, the electromagnet is adjacent to the armature, the spring is in contact with the armature and the end cover is fixedly connected with the flange. According to the unidirectionally-braking electromagnetic safety brake disclosed by the invention, based on a traditional disc type electromagnetic brake, a one-way clutch is built-in reasonably, thus transmission components with two functions are organically combined, and the one-way braking moment can be selectively supplied; in addition, the other direction is free, one-way braking can be carried out and the free rotation in the other direction can be carried out without manual intervention to release risks in a power failure state.

Description

technical field [0001] The invention relates to an electromagnetic safety brake, in particular to a one-way braking electromagnetic safety brake. Background technique [0002] In industrial transmission technology, electromagnetic safety brake is an important application form. It mainly works in the power-off state, and provides braking protection for the equipment in the case of power loss. Due to the electromagnetic mode of operation, this type of brake usually works in a 0-1 state, that is, in a de-energized state, and cannot be adjusted in any way except by manual intervention. With the development of modern transmission technology, the safety requirements for brakes are getting higher and higher, such as wind power equipment such as construction, machinery, fans, pumps, and even automobile brakes (slope applications) are required to provide a one-way braking electromagnetic brake . This kind of electromagnetic brake can perform one-way braking in the state of power f...
