By adding a brake body and a brake pad, three groups of brake pads are installed, and the three groups of brake pads are installed on the right side of the armature disk in a circumferentially evenly distributed manner through hexagon socket bolts, so that a single group of brake pads can be replaced separately.

Description

Technical Field

[0001] The utility model belongs to the technical field of brakes, and particularly relates to an electromagnetic reverse brake. Background Art

[0002] The electromagnetic reverse brake is a braking device that works on the electromagnetic principle. It is mainly used to quickly brake or maintain a certain position of a motor or other rotating equipment. The working principle of this brake is based on the reverse action of electromagnetic force. When the electromagnetic coil is energized, the brake is released from the braking state. When the coil is de-energized, the brake is braked by the spring or gravity. The electromagnetic coil in the electromagnetic reverse brake is an important component and a key part that determines whether the brake is braked or not. When the electromagnetic reverse brake is used for a long time or braked frequently, its electromagnetic coil is in a high-use state, so the electromagnetic coil will face damage and other situations. This requires the electromagnetic coil of the electromagnetic reverse brake to be repaired or replaced. Most of the electromagnetic coils in the common electromagnetic reverse brake are fixed by bolts and other methods. When repairing or replacing the electromagnetic coil, it is often necessary to use additional tools for disassembly and assembly, which makes it inconvenient to disassemble and assemble the electromagnetic coil, which is not conducive to quickly repairing the electromagnetic reverse brake to restore it to normal working state.

[0003] Secondly, the fixing bolts used by different electromagnetic reverse brakes may be different, which makes some wrenches unusable, resulting in an increase in the number of tools that need to be prepared.

[0004] In summary, there are some problems in the use of the electromagnetic coil bolt-fixed structure in the electromagnetic reverse brake, so it is hoped to propose a new structure to solve the above technical problems. Utility Model Content

A group of armature springs are provided at the upper and lower ends of the right side surface of the left main body.
