Abstract
The utility model relates to an electromagnetic braking device comprising an iron core assembly, a guide pin (5) is arranged on the iron core assembly and is connected with an armature (9), a brake disc (10) is fixedly clamped between the armature (9) and a traction machine, friction plates (11) are arranged at two sides of the brake disc (10) and are connected with a rotating shaft of the traction machine by splines. The electromagnetic braking device is characterized in that a chute (13) is arranged in a ring-shaped area at the contact position of the armature (9) and the friction plates (11). By arranging the chute on the armature of the braking device, the friction force between the armature and the braking disc can be enhanced, therefore, the braking force of the braking device is enhanced and the braking effect of the braking device is improved. Furthermore, due to the design of the chute, an air gap of the contact surface is added, so that the braking noise of a brake can be remarkably reduced by more than 5dB.
Description
Technical field
The utility model relates to the electro-magnetic braking device of a kind of brake equipment, particularly a kind of elevator traction machine.
Background technology
At present, along with the continuous development of national economy and the raising of people's living standard, modern high-rise building spreads all over town and country.For guaranteeing rapid, the safety of flow of personnel in the skyscraper, satisfy the allegro needs of the modern life, improve the in-use performance of operating efficiency and equipment, also more and more higher to the design and the manufacturing requirement of elevator.And the deceleration and stopping performance of towing machine directly has influence on the safety and effectiveness of elevator.Existing towing machine brake equipment friction lining all is set on brake disc, to improve the braking force of brake equipment.But how by simple structure, further improve friction force to increase the braking force of brake equipment, be the difficult problem that those skilled in the art need solution badly always.
The utility model content
The purpose of this utility model is, a kind of electro-magnetic braking device is provided.It can increase the braking force of brake equipment, promotes the braking effect of drg.
The technical solution of the utility model: a kind of electro-magnetic braking device, comprise core assembly, core assembly is provided with guide finger and links to each other with armature, clamping has brake disc between armature and the towing machine, the brake disc both sides are provided with friction lining, and link to each other with the rotating shaft of towing machine by spline, it is characterized in that: described armature with the annular region of the contact position of friction lining, be provided with skewed slot.
In the aforesaid electro-magnetic braking device, described skewed slot is evenly arranged, and becomes 30～60 degree with the straight line of crossing skewed slot mid point and armature center.
In the aforesaid electro-magnetic braking device, the described skewed slot degree of depth is 2～5mm, and width is 1～3mm, is spaced apart 6～10mm.
Compared with prior art, the utility model is by being provided with skewed slot on the armature of brake equipment, can increase the friction force between the friction lining of armature and brake disc, thereby increased the braking force of brake equipment, promoted the braking effect of brake equipment.And the design of skewed slot has increased the air gap of contact surface, can significantly reduce more than the brake noise 5dB of drg.
