2. A metallurgical reducer according to claim 1, wherein: and the small holes are staggered with nut inner holes or air holes.

Technical Field

The invention relates to a speed reducer, in particular to a speed reducer for metallurgy.

Background

The speed reducer for metallurgy needs to be lubricated, ventilative, visual control because of its high temperature environment characteristic of use, and when the speed reducer carries out oil spray lubrication, lubricating oil easily sputters from ventilative cap blowout, influences the service environment, and disposes ventilative cap and sight hole structure alone, is unfavorable for retrenching the structure, increases the manufacturing cost.

Disclosure of Invention

The invention provides a speed reducer for metallurgy, which has a simple structure, combines a ventilation cap and a visual hole, and effectively prevents the ventilation cap from sputtering and spraying oil.

The technical scheme adopted by the invention is as follows: the utility model provides a speed reducer for metallurgy, includes the box, and the box top is equipped with towards the lubricated oil spout of box inside oil spray, and box lower part lateral wall is equipped with oil drain port, its characterized in that: the side wall of the upper part of the box body is provided with a sight hole, a sight hole cover is arranged on the sight hole, an air vent is arranged on the sight hole cover, an installation nut corresponding to the air vent is arranged on the inner side of the sight hole cover, or the air vent is a threaded hole, a ventilation cap is screwed on the air vent through an installation nut or threaded hole structure, a blocking cover for covering the installation nut or the air vent is arranged on the inner side of the sight hole cover, and a small hole is arranged on.

And the small holes are staggered with nut inner holes or air holes.

According to the invention, the vent hole is formed in the viewing hole cover, the mounting nut or the vent hole internal thread is screwed with the ventilation cap, the ventilation cap and the visual hole are combined, the processing of the speed reducer box body is simplified, the production and manufacturing cost is reduced, meanwhile, the mounting nut or the inner side of the vent hole is covered with the blocking cover with the small hole, the small hole is staggered with the mounting nut inner hole or the vent hole, the normal ventilation and the lubricating oil sputtering prevention are both realized, the sputtering oil injection of the ventilation cap can be effectively prevented, and the safe and environment-friendly ventilation and visual monitoring operation is ensured.
