Description

Technical Field

[0001] The utility model relates to the technical field of brake equipment, in particular to a fully enclosed electromagnetic brake. Background Art

[0002] The brake connection to the motor must be installed at the rear of the motor. The motor's rear cover requires a flat mounting surface, the motor shaft must be modified, the bushing mounting position must be machined, and the brake air hood must be lengthened. This work is beyond the capabilities of non-professionals. Furthermore, because the brake base plate, brake pads, and brake armature plate are exposed to harsh conditions for a long time, the original electroplating layer of the electromagnetic brake corrodes and oxidizes, leading to rust or dust accumulation. This can cause the electromagnetic brake to malfunction and fail to operate properly, shortening its service life.

[0003] In view of this, we propose a fully enclosed electromagnetic brake to solve the existing problems. Utility Model Content

[0006] Preferably, the coil body has at least one coil groove on a side facing the brake base plate, and the coil groove is recessed inward from the bottom of the second accommodating groove. The coil body also includes a coil, and the coil is arranged in the coil groove.

[0007] Preferably, the coil groove and the second accommodating groove are integrally formed.

[0008] Preferably, the armature plate, brake pad and brake base plate are sealed in the first receiving groove and the second receiving groove of the coil body, so that the core components of the fully enclosed electromagnetic brake are not exposed to the external environment, effectively avoiding corrosion, oxidation and other problems of the fully enclosed electromagnetic brake, and greatly extending the life of the fully enclosed electromagnetic brake.

[0009] Preferably, the coil body has three through holes, and the through holes are connected to the armature plate gap sleeve and the brake base plate, wherein the armature plate, the brake pad and the base plate are stacked in sequence, and the brake spring on the coil body is used to press the armature plate against the brake pad and the base plate, so that the brake pad generates friction with it.

[0010] Compared with the prior art, the beneficial effects of the present invention are:

[0011] The utility model designs the brake as an independent component. When it is needed for emergency braking or locking the shaft to prevent the motor from rotating due to power failure, the brake can be directly taken out and installed in the front section of the motor output shaft and locked. No modification, processing or other processes are required, and the installation is easy. BRIEF DESCRIPTION OF THE DRAWINGS

[0015] The technical solution of the present invention is further described below with reference to the accompanying drawings and specific embodiments.

[0016] Example 1

[0017] like Figure 1 As shown, the utility model proposes a fully enclosed electromagnetic brake, including a front flange 6, a coil body 2, an armature plate 3, a brake pad 4, a brake base plate 5, an input flange 1 and an oil seal 7, which are arranged in sequence from left to right. The front face of the coil body 2 has a protruding guide, which tightly fits with an inwardly recessed receiving groove on one side of the front flange 6 to ensure sealing. The side of the coil body 2 facing the brake base plate 5 has an inwardly recessed receiving groove. The armature plate 3, the brake pad 4 and the brake base plate 5 are coaxially arranged in the receiving groove in sequence, and the brake base plate 5 is sealed with the inner wall surface of the receiving groove of the coil body 2. The base plate has an inwardly recessed receiving groove that tightly fits with the protruding guide of the input flange 1. Furthermore, the front flange 6 and the input flange 1 have inner holes that can be equipped with oil seals 7, which can tightly fit with the brake axis.

[0018] Furthermore, the coil body 2 has at least one coil groove on one side facing the brake base plate 5, and the coil groove is recessed inward from the bottom of the accommodating groove. The fully enclosed electromagnetic brake also includes a coil, and the coil is arranged in the coil groove.

[0019] Furthermore, the coil groove and the accommodating groove are integrally formed.

[0020] Furthermore, by sealing the armature plate 3, the brake pad 4 and the brake base plate 5 in the receiving groove of the coil body 2, the core components of the fully enclosed electromagnetic brake are not exposed to the external environment, effectively avoiding the corrosion, oxidation and other problems of the fully enclosed electromagnetic brake, and greatly extending the life of the fully enclosed electromagnetic brake.

[0021] Furthermore, the brake coil body 2 has three through holes and is connected to the armature plate 3 through a gap sleeve and the brake base plate 5, wherein the armature plate 3, the brake pad 4 and the base plate are stacked in sequence, and the brake spring on the coil body 2 is used to press the armature plate 3 against the brake pad 4 and the base plate, so that the brake pad 4 generates friction with it.

[0022] Furthermore, there is an external C buckle on the integrated gear shaft. After the bearing is pressed into the limit, the C buckle is clamped to limit the bearing, and then it is matched with the brake pad 4 that passes through. The bearing also has a bearing chamber on the base plate to fix the position to achieve overall positioning.

[0023] Furthermore, the front flange 6 has four dish-shaped holes connected to the base plate, which can make it tightly connected without interfering with other components. The front flange 6 has an oil seal 7 to seal its front end. The input flange 1 also has four dish-shaped holes to connect to the front of the coil body 2. The input flange 1 also has an oil seal 7 to seal its rear end.

[0024] Furthermore, the coil body 2 has a wire outlet hole and two threaded holes for installing a waterproof wire box to seal the entire machine. The waterproof wire box can be installed with a rectifier for users with different voltage requirements.

[0025] Furthermore, the PCD mounting holes of the input flange 1 are aligned with those of the matching motor, allowing for direct installation and securement. The front flange 6 of the present invention is consistent with the motor's front flange 6 in terms of outer diameter, guide, PCD mounting hole, and output shaft parameters, allowing users to quickly install without having to modify the original equipment.

[0026] The above specific embodiments are only several preferred embodiments of the present invention. Based on the technical solutions of the present invention and the relevant inspirations of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above specific embodiments.
