(54) SEAL TRACK CHAIN SEAL

one

The invention relates to the field of transport engineering, mainly to tracked vehicles,

According to the main author. St. No. 518409. Known is the seal of the hinge of the track chain, containing cuffs reinforced with rings made in the form of petal spring. washers 1.

However, such a seal is not long-lasting, because if two petal washers are installed, the latter can move with one another, thus disrupting their connection.

The purpose of the invention is to increase the durability of compaction by increasing its elasticity.

This is achieved by the fact that in the proposed seal between the petal spring washers, a separating ring is installed around the circumference of the inner diameter.

FIG. 1 shows a seal; in fig. 2 - distance ring.

Seal 1 of the hinge track chain contains pair-mounted petal spring washers 2 installed with camber

outward or inward. A circumferential ring 3 is installed between the washers around the circumference and inner diameter; this ensures an increase in the elasticity of the connection of the spring washers 2. The seal is mounted on the finger 4. There is a sleeve b inside the link 5 of the track chain. The end of the finger 4 is installed in the boss 7 near the located link. Between vtul1 oy 6 and link 5 on the finger 4 is installed a distance ring 8,

Compaction works as follows.

The edges of the seal 1 are adjacent to the boss 7 and the sleeve 6, thereby sealing the hinge. Seal 1 has the necessary elasticity due to the fact that it is reinforced with lobe washers 2, which have a long stroke. Ring 8 serves to protect the seal from increased axial force during assembly and operation, and ring 3 provides increased elasticity.

Thanks to this seal design, it is durable and reliable.
