Abstract
The invention relates to the field of brakes, in particular to a power-losing electromagnetic brake free of air gap measuring. The power-losing electromagnetic brake free of air gap measuring comprises a magnetic conductor. A plurality of mounting bolts are arranged on the magnetic conductor. Meanwhile, the uppermost end of each mounting bolt is connected with a hollow bolt. An armature is arranged on the upper end face of the magnetic conductor and connected with the hollow bolts. A nylon air gap positioning clamp is arranged outside the hollow bolts and located at the upper end of the armature. The power-losing electromagnetic brake has the beneficial effects that an air gap can be fixed within a reasonable value range through the open nylon air gap positioning clamp, a user can directly assemble the power-losing electromagnetic brake on a machine without conducting air gap adjustment and measurement, and accordingly the performance of the power-losing electromagnetic brake can be given into play to a greater extent.
Description
Technical field
The present invention relates to brake field, specifically a kind of powerless magnetic brake exempting to survey air gap。
Background technology
The application of present brake is further frequent, is typically all in armature adhesive to the adhesive face of magnetic conductor by suction against the force of the spring, thus releasing braking, now braking dish is in release conditions, will rotate freely along with motor shaft；When magnetic conductor power-off, magnetic attraction force disappears, and armature be will push against this side of braking dish under spring force, thus producing brake force, it is achieved power-off brake (brake)。But the air gap (δ) wherein between magnetic conductor and armature is very crucial, in prior art, this air gap passes through hollow bolt, adjusts to theoretical value energising test with clearance gauge。But so hollow bolt is not done axial restriction, it is easy to cause that air gap changes, and user is also performed to air gap adjustment and closes and measure。So needing a kind of powerless magnetic brake exempting to survey air gap。
Summary of the invention
It is an object of the invention to provide a kind of powerless magnetic brake exempting to survey air gap。
For realizing such purpose, the technical scheme is that a kind of powerless magnetic brake exempting to survey air gap, it is characterized in that, the described powerless magnetic brake exempting to survey air gap includes magnetic conductor, described magnetic conductor is provided with multiple installation bolt, each described installation bolt is topmost connected to a hollow bolt simultaneously, simultaneously in described magnetic conductor upper surface, and it is connected with hollow bolt, it is provided with an armature, outside described hollow bolt and be also at armature upper end position place and be provided with a nylon air gap locator card。
Described a kind of powerless magnetic brake exempting to survey air gap, it is characterised in that the setting of described nylon air gap locator card so that there is between armature and magnetic conductor an air gap。
Described a kind of powerless magnetic brake exempting to survey air gap, it is characterised in that be provided with three on described powerless magnetic brake and install bolt。
The beneficial outcomes of the present invention:
The present invention adopts nylon open-type air gap locator card then can be fixed in reasonable value range by air gap, and user does not need to carry out air gap adjustment conjunction and mensuration, so that it may directly install, thus from the performance that more can give full play to this product。
