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 Shown is the front of a motor 1, such as an explosion-proof motor, where a mounting flange 3 with through holes 4 is provided in front of the frame 2 to mount the motor using screws, bolts, etc. Projecting from the front of the frame 2 is an end portion 5 of the motor shaft, said end portion having a slot 6 for receiving 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 said casing consists of a first part 11 designed to be mounted on the flange 3 of the electric motor 1; The second part 12, which is provided with a seal, is 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 can be of any shape and size, or a shape and size similar to the mounting flange 3 of the motor 1, such as figure 1 As shown, and with the through holes 14, its arrangement is...

Abstract

The invention relates to a braking device (10) of a mechanism driven by an electric motor (1), in particular described as an explosion-proof electric motor. The casing (11, 12) of the device is detachable from the frame (2) of the electric motor, and the casing includes a shaft (20) which connects, in rotation, to a shaft (5) driven by the electric motor connection device.

Description

technical field [0001] The present invention generally relates to a braking device for a mechanism driven by an electric motor, and in particular, relates to a braking device for a mechanism driven by an explosion-proof electric motor. Background technique [0002] Explosion-proof motors are usually installed in places or environments where substances that may cause combustion and / or explosion are present. For these reasons, explosion-proof motors must be manufactured to ensure that the internal parts of the motor are completely isolated from the external environment. In addition to the widespread use of seals, machining is required to be extremely precise to achieve extremely tight tolerances. Therefore, the production of electric motors with explosion-proof properties is inherently complicated 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 co...
