The invention relates primarily to precision engineering.

The purpose of the invention is to increase the reliability of transmission by providing guaranteed lubrication of the transmission during long-term operation.

Fig, 1 shows a gear transmission, a cut along the shafts; in Fig.2 a section aa in Fig.1.

A gear transmission contains a housing 2 placed in support 1, which is filled with grease 3. The housing 2 consists of two parts 4 and 5

In the left part 4 of the housing (Fig. 2), at least two shafts 6 and 7 are installed with gear wheels, respectively 8 and 9. Second, the right part 5 of housing 2 is placed in the support 1 with the possibility of rotation relative to the first and kinematically connected with gears 8 and 9 due to the thickening on the inner surface of the right part 5 of the crown ring 10 and is placed in the casing 2 of an additional gear that interacts with the gear 10 and the gear 9.

In the housing in the right part 5, four pieces of radial partitions 12 are placed to hold the lubricant and ensure its rotation together with the housing. The baffles are rectangular plate profiles that are installed so as not to hinder the rotation of the gear unit.

with gears 8 and 9 Gear gear works as follows. When the gear wheels 8, 9 and 11 are rotated, their teeth capture the lubricant and throw it to the periphery. As a result of the interaction of the wheel 11 with the ring gear O - on the inner surface of the housing, the latter slowly rotates together with the lubricant 3, 2 sludge.

Gear transmission works as follows.

B the initial moments of rotation of gear wheels. 8, 9, and 11, their teeth capture lubricant particles and, under the action of centrifugal forces, throw it to the periphery, resulting in a gap.

At the same time, the gear wheel 11, interacting with the ring gear 10, begins to slowly rotate the housing 2 together with the lubricant 3. After a certain predetermined period of time as the body rotates, the lubricant 3 again touches the wheel 11 and partially passes to the gear tooth, after which a gap is formed again between grease and gear teeth 8 and 9,

Formula C1 inventions
