3. The scraper oil scraping lubrication speed reducer as claimed in claim 2, wherein: the upper edge of the outer groove plate is lower than the main shaft.

Technical Field

The invention relates to a speed reducer, in particular to a scraper oil scraping lubrication speed reducer.

Background

The lubrication of the existing speed reducer is mostly carried out by spraying and lubricating the lubricating oil pumped to the top by an external oil tank of the machine body or the lubricating oil pumped to the lower part in the machine body through an external lubricating pump or a self-contained lubricating pump, the lubrication of the existing speed reducer can effectively aim at the meshing part of gears and worm gears, but the existing speed reducer does not have better lubrication on a supporting bearing positioned on the side wall of the box body.

Disclosure of Invention

The invention provides a scraper oil scraping lubrication speed reducer which is simple in structure and can effectively lubricate a supporting bearing on the side wall of a box body.

The technical scheme adopted by the invention is as follows: the utility model provides a scraper blade frizing lubrication speed reducer, includes box, main shaft, worm wheel, worm axle, and the worm wheel meshing worm axle output in the main shaft cross-under box, the perpendicular meshing of worm wheel sets up the worm axle top in the box, its characterized in that: the oil collecting device is characterized by further comprising a scraping plate and an oil pool groove, wherein the scraping plate is arranged in the center of the two side faces of the worm wheel in a front-back mode, the vertical gaps are formed between the front portion and the rear portion of the center of the two side faces of the worm wheel, the bottom of the scraping plate is connected with an oil collecting groove, the oil pool groove is formed in the inner wall of the box body parallel to the two side faces of the worm wheel.

The oil sump groove structure is a groove-shaped structure with an upward opening, the outer groove plate is obliquely abutted against the inner wall of the box body, the oil sump groove is not provided with an inner groove plate, the oil sump groove is directly communicated with a supporting bearing of the main shaft, and the oil collecting groove is correspondingly connected to the outer groove plate.

The upper edge of the outer groove plate is lower than the main shaft.

When the worm wheel is meshed with the worm shaft, the lubricating oil at the lower part in the speed reducer box body is brought to the front and rear positions of the center by the side face of the worm wheel, the lubricating oil is scraped to fall to the oil collecting groove at the bottom of the worm wheel by the scraping plate, the lubricating oil flows to the oil pool groove through the oil collecting groove, and the lubricating oil in the oil pool groove is directly communicated with the position of the supporting bearing on the side wall of the box body, so that the worm wheel is sufficient in lubrication, and the service.

Drawings

FIG. 1 is a schematic structural view of the present invention;

fig. 2 is a left side view in half section of fig. 1.

In the figure: the device comprises a box body 1, a main shaft 2, a supporting bearing 3, a worm wheel 4, a worm shaft 5, a scraping plate 6, an oil collecting tank 7, an oil pool tank 8 and an outer trough plate 9.

Detailed Description

The following further description is made in conjunction with the accompanying drawings and examples.

As shown in fig. 1 and 2, the scraper oil scraping lubrication speed reducer comprises a box body 1, a main shaft 2, a support bearing 3, a worm wheel 4, a worm shaft 5, a scraper 6, an oil collecting tank 7 and an outer tank plate 9. The main shaft 2 is connected on the box body 1 in a penetrating mode through the supporting bearing 3, the worm wheel 4 is connected on the main shaft 2 in a penetrating mode, the worm wheel 4 is meshed with the worm shaft 5, an oil pool groove 8 is formed in the side wall of the box body 1 at the position of the supporting bearing 3, the oil pool groove 8 is lower than the main shaft 2, the oil pool groove 8 is formed in the mode that an outer groove plate 9 is obliquely connected on the side wall of the box body 1 in a surrounding mode and does not have an inner groove plate, the oil pool groove 8 is directly connected with the side wall of the box body and is directly communicated with the supporting bearing 3, the upper portion of the outer groove plate 9 is connected with an oil collecting groove 7 communicated with the oil collecting groove, the oil collecting groove 7 is connected with the front portion of the center.
