[0030] Such as Figure 1-6 As shown, a reducer wet normally closed brake in this embodiment includes a reducer cylinder 1, an input shaft 2, an inner friction plate 3 and an outer friction plate 4 that are set in the cylinder cavity and fitted on the input shaft 2, The reducer cylinder 1 is provided with a brake working chamber 5 and a lubricating oil storage chamber 6 wrapped on the outer surface of the brake working chamber 5, and the inner friction plate 3 and the outer friction plate 4 are arranged in the brake working chamber 5, the oil level of the lubricating oil storage chamber 6 is higher than the height of any inner friction plate 3 or outer friction plate 4, so that the brake can be immersed in the lubricating oil as a whole, exchange heat directly, and improve the heat exchange level. The lubricating oil storage chamber 6 is provided with an oil filling port 7 communicating with the outside, which is convenient for directly adding lubricating oil into the lubricati...

[0040] Such as Figure 7 As shown, the difference from the first embodiment is that in this embodiment, a vertical through groove 14 is provided between the lubricating oil storage chamber 6 and the brake working chamber 5, and the vertical through groove 14 is arranged on the inner friction plate 3 and the outer friction plate 3. On the circumferential area corresponding to the friction plate 4, multiple vertical through grooves 14 can be arranged along the circumferential direction to improve the heat dissipation effect. At the same time, the length of the vertical through groove 14 is greater than the total thickness of the inner friction plate 3 and the outer friction plate 4, namely Heat dissipation for all friction plates, further improve the working environment of the brake, improve heat dissipation effect and service life.

Abstract

The invention discloses a reducer wet normally closed brake, which belongs to the technical field of reducer brakes, and comprises a reducer cylinder body, an input shaft, an inner friction plate and an outer friction plate set in the cylinder cavity and sleeved on the input shaft. The cylinder body of the reducer is provided with a brake working cavity and a lubricating oil storage cavity wrapped on the outer surface of the braking working cavity, the inner friction plate and the outer friction plate are arranged in the braking working cavity, and the lubricating oil storage The oil level of the storage chamber is higher than the height plane where any inner friction plate or outer friction plate is located, and the lubricating oil storage chamber is provided with an oil filling port communicating with the outside. In the present invention, by setting the lubricating oil storage chamber whose oil level is higher than that of the friction plate, the whole brake is soaked in the lubricating oil to directly exchange heat, reduce the calorific value of the brake, improve the service life, and at the same time enable the brake to be used for higher Speed, extending its application occasions.

Description

technical field [0001] The invention belongs to the technical field of reducer brakes, and in particular relates to a wet normally closed brake used for the braking of a reducer. Background technique [0002] The existing planetary reducer brakes have the following problems: the lubricating oil circulation in the brake does not have a special oil inlet and outlet circulation path, and only exchanges through the gap between the outer friction plate and the cylinder body, the oil circulation is limited, and the heat exchange level Poor, resulting in brake heat accumulation, high temperature, and increased wear, thereby reducing the service life of the brake and even the reducer. At the same time, the lubricating oil only enters the gearbox through the friction plate, which is inefficient and inconvenient. [0003] In view of the above problems, it is necessary to improve the structure of the existing brake and add a special lubricating oil channel, which can quickly take away ...
