SU529953A1 - Device for liquid lubrication of open gear mechanical press - Google Patents

Description

The invention relates to the field of forging and pressing machinery, in particular, to devices for lubricating gears of 13 open gears of mechanical presses.

Modern mechanical presses are known, and the main drive element is open (located on the tan part of the bed) gear 1.

Known; 1s also the advantages of liquid omazka elements of presses, including the gears of their drives, then sra | vnemu with grease 2.

The use of liquid is lubricated in open gear mechanical presses requires a guaranteed exclusion of the possibility of lubricant leaks, as they lead to contamination of the machine and the workplace, and in forge shops (for example, in the mountains there are cementing and edging presses, metal heated to forging temperature ), leaks may cause a fire.

Therefore, in known open-gear gearing systems of press presses, hermetic cavities or crankcases are used, according to the design of which the systems can be divided into two groups 3, 4.

by stubs in the place of exit of the shafts on which gears gears are mounted, from the bed and crankcase. The disadvantage of this design is the possibility of failure of seals, the replacement of which requires the dismantling of gears from the shafts.

Another structure is characterized in that the gears of the transmission are placed in the cavity formed by the artificially developed walls of the crosshead of the press, which together with the cover form a sealed housing. This design is highly reliable, but is associated with a significant increase in size and weight of the press beam, and since gaba rits are not determined by its strength and stiffness, but solely by the dimensions of the gear train, which is formed by artificially developed crossheads.

The aim of the invention is to provide an open gear lubrication system for a mechanical press, | Without seals, subject to wear or aging, ensuring minimum dimensions and weight.

In the proposed device, this is due to the fact that B: 1 the crankcase portion adjacent to the bed is provided with protrusions covering the gear shafts and orienting the lubricant leaks into the cavity connected to the drain pipe.

FIG. 1 shows the device, a general view; 1ha of FIG. 2 is a section through lo-A in FIG. one; in fig. 3 - on the fit. 2

The crankcase /, inside of which gears 2 and 3 of gear and gear are located, is fixed on the crossbar 4 presses by means of bolts 5. The outer part of the crankcase is closed by a lid 6, which forms a labyrinth seal with the surface of the press 7 which is built in the shunt-nu. Roofs 8 are welded to traverse 4, forming a cavity for collecting oil flowing out at the junction of the casing / with grass. 4. This cavity is connected to the drain pipe} 0 discharging working oil from the crankcase U.

Oil from the feed pipe // goes to the place of engagement of the gears 2 and 3 (see Fig. 1) and then flows down the crankcase walls downwards, from where it is removed through the drain pipe 0 (see Fig. 2). A part of the oil, which is sprayed by a gear drive or when it flows out of Podschippiks of its shafts, leaks at the junction of the crankcase / with the crossmember 4. Since these / places on the crankcase are made in the form of L-shaped projections (see Fig. 2, 3). the gear shafts, the oil leaks are directed only towards the oil-receiving cavity formed by the traverse 4 visors 5, from which the pipe 9 is diverted into the drain pipe 10.
