Abstract
A displacement compensation device of an electromagnetic disc brake comprises a spring, a guide post, a brake armature and a brake magnetic yoke, and is characterized in that a top sleeve is fixedly connected with the brake armature through a bolt, the top sleeve and the brake armature are both sleeved on the guide post, a conical sleeve is arranged between the top sleeve and the brake armature, a steel ball and the spring are arranged in the conical sleeve, and the steel ball is contacted with the top sleeve under the action of the spring force; the disc brake magnetic yoke is fixedly arranged on the outer side surface of the conical sleeve. The utility model discloses an electromagnetism disc type stopper displacement compensation arrangement can realize the air gap automatic compensation function under the condition that does not change the current foundation structure of electromagnetism disc type stopper to avoid the stopper because of the air gap too big, the unable incident that releases and lead to of stopper, and can prolong the maintenance adjustment cycle of stopper and improve the factor of safety of whole driving chain.
Description
Technical Field
The utility model relates to an industrial brake field specifically is an electromagnetism disc type stopper displacement compensation arrangement.
Background
The electromagnetic disc brake is a commonly used brake in the industrial field, and is generally used for hoisting equipment braking, wind power equipment braking, light industry mechanical braking and the like. The existing electromagnetic disc brake mainly comprises a magnetic yoke provided with a coil, an armature, a spring, a friction disc, a spline sleeve and other parts, wherein the spring is arranged in the magnetic yoke, and the armature can move along the axial direction. The magnetic yoke is fixed on the base by mounting screws, after the air gap is adjusted to a specified value, the spline sleeve is connected with the transmission shaft by a key, and the external spline of the spline sleeve is matched with the internal spline of the friction disc. When the coil is powered off, under the action of spring force, the friction disc, the armature and the base generate friction force, and the transmission shaft is braked through the spline sleeve; when the coil is electrified, the armature is attracted to the magnetic yoke under the action of electromagnetic force, so that the friction disc is loosened, and the brake is released. The rated air gap of the electromagnetic disc brake is enlarged due to abrasion, when the air gap exceeds the maximum air gap value, the brake cannot be released or the braking torque is small, even a great accident is caused, and therefore the air gap must be frequently checked and readjusted.
Disclosure of Invention
The utility model aims at providing an electromagnetism disc type stopper displacement compensation arrangement that simple structure, stability are good, need not artificial adjustment air gap value.
The utility model discloses an electromagnetic disc type brake displacement compensation device, including spring, guide pillar, stopper armature, stopper yoke, its characterized in that, the top cover passes through bolt and stopper armature fixed connection, and both are overlapped on the guide pillar, and the taper sleeve sets up between top cover and stopper armature, and steel ball, spring mounting are in the taper sleeve, and the steel ball contacts with the top cover under the effect of spring force; the disc brake magnetic yoke is fixedly arranged on the outer side surface of the conical sleeve.
The utility model discloses an electromagnetism disc type stopper displacement compensation arrangement's theory of operation is, and the top cover links with stopper armature when electro-magnet actuation and release, and the toper cover links with the stopper yoke. When the air gap of the brake is normal, the spring enables the steel ball to clamp the gap between the conical sleeve and the guide post through pretightening force, so that the magnet yoke of the brake is fixed; when the friction gasket is abraded and the air gap is enlarged, the ejector sleeve presses the steel ball to separate from the conical sleeve, and when the brake is electrified and attracted, the armature of the brake drives the ejector sleeve to separate from the steel ball; at the moment, the brake magnetic yoke and the conical sleeve are in a free state, move towards the steel ball under the action of self weight, move to the steel ball to clamp the gap between the conical sleeve and the guide post again, and the downward movement displacement of the brake magnetic yoke and the conical sleeve is the compensation value of the air gap of the brake. When the friction lining is worn to the maximum value next time, the action is repeated, and the brake has the function of air gap automatic compensation.
The utility model discloses an electromagnetism disc type stopper displacement compensation arrangement can realize the air gap automatic compensation function under the condition that does not change the current foundation structure of electromagnetism disc type stopper to avoid the stopper because of the air gap too big, the unable incident that releases and lead to of stopper, and can prolong the maintenance adjustment cycle of stopper and improve the factor of safety of whole driving chain.
