Problems solved by technology

[0005] Furthermore, given the delicate handling required in the manufacture of self-braking electric motors with explosion-proof properties, any problem arising in the brake or electric motor alone inevitably leads to the need for replacement of the entire mechanism
In fact, any repair and / or overhaul operation that replaces one or more components in the entire mechanism may affect its explosion protection performance and thus pose an unacceptable risk for the specific application for which it is intended

Embodiment Construction

[0025] Figure 1 shows the front of a motor 1, such as an explosion-proof motor, in which a mounting flange 3 with through holes 4 is provided on the front of the frame 2 for mounting the motor using screws, bolts, or the like. Projecting from the front of the frame 2 is an end portion 5 of the motor shaft, said end portion having a slot 6 to accommodate known connectors such as keys.

[0026] The braking device 10 according to the embodiment shown here comprises a casing with an explosion-proof seal, wherein the casing consists of a first part 11 designed to be mounted on the flange 3 of the electric motor 1; and a first part 11; The second part 12 is provided with a seal fixed to the first part 11 in a detachable manner. The front of the second part 12 of the casing includes a mounting flange 13, wherein the mounting flange 13 may be of any shape and size, or similar to the mounting flange 3 of the motor 1, as shown in Figure 1 shown with through holes 14 in the same arrange...

Abstract

A braking device for equipment driven by an electric motor, in particular by an explosion-proof electric motor, is described. The casing of the device is separate from the frame of the electric motor and means are provided for connecting during rotation the rotating shaft to a shaft of the brake device driven by an electric motor.

Description

technical field [0001] The present invention generally relates to a braking device for a mechanism driven by an electric motor, and in particular, to a braking device for a mechanism driven by an explosion-proof electric motor. Background technique [0002] Explosion-proof electric motors are usually installed in locations or environments where substances that may cause combustion and / or explosion are present. For these reasons, explosion-proof motors must be manufactured so that the internal parts of the motor are completely isolated from the external environment. In addition to the widespread use of seals, particularly precise machining is required to achieve extremely tight tolerances. Therefore, the production of electric motors with explosion-proof properties is itself complex and expensive. [0003] If it is necessary to manufacture an explosion-proof motor with self-braking performance, it will be more complicated and further increase the processing cost, in other w...
