Detailed Description

The technical scheme of the utility model is further explained by combining the drawings and the embodiment.

As shown in the figure, the wear-resistant transmission system of the vertical circulating garage comprises a motor, a speed reducer, a driving disc 4 and a chain 2, wherein guard plates 3 are uniformly distributed on the chain 2, the upper ends of the guard plates 3 are fixedly connected onto chain links 7 of the chain 2, and the bottom ends of the guard plates 3 are rotatably connected onto a bearing shaft 6 of a support frame 5.

In order to ensure that the guard plate 3 can be positioned at the topmost end when the trailer frame 5 rotates to the top end of the main body frame 1, the number of the chain links 7 at the driving disc 4 needs to be limited. In this embodiment, the number of the drive disks 4 corresponding to the number of the links 7 is 5.

The chain link 7 is composed of a pair of oblong steel plates 8, and two ends of each steel plate 8 are connected through pins 10. Be provided with gasket 9 between pin 10 and the steel sheet 8, the pin 10 end sets up the through-hole, sets up a few font card silk 12 in the through-hole, and pin 10 realizes dying to the lock of steel sheet 8 through card silk 12. The pin 10 is sleeved with a roller 11, and the roller 11 is positioned between the steel plates 8. A copper sleeve 13 is also arranged between the pin 10 and the roller 11, and the copper sleeve 13 is fixed on the pin 10. Compared with a bearing, the copper sleeve 13 is made of self-lubricating materials, does not need to be frequently lubricated, is high in bearing capacity, does not need to consider the condition of removing beads, is wear-resistant and has a long service life.

The bottom end of the guard plate 3 is provided with a shaft hole, and a steel wear-resistant shaft sleeve 17, a copper oilless bushing 16 and a locking sleeve 18 are nested in the shaft hole. One end of the wear-resistant shaft sleeve 17 is provided with a limiting ring, the other end of the wear-resistant shaft sleeve is locked through a nut 14, and a check washer 15 is arranged between the nut 14 and the guard plate 3. The oilless bushing 16 replaces the bearing, reducing wear losses at the connection. The locking sleeve 18 is locked at the end part of the bearing shaft 6 through internal threads, and the tail end of the locking sleeve 18 is provided with a limiting ring for preventing falling. The two ends of the bearing shaft 6 are limited by the limiting rings, so that the bearing shaft 6 is prevented from falling off from the guard plate 3.

In conclusion, the wear-resistant transmission system of the vertical circulating garage adopting the structure uses the self-lubricating component to replace a bearing, frequent lubrication is not needed, the wear-resistant performance is good, and the service life is long.
