In order to achieve the above object, the present utility model is realized by the following technical scheme: the utility model provides a tension compression roller, includes dabber and roller, the dabber is located the roller, the gland has all been installed at the both ends of roller, installs the biserial tapered roller bearing corresponding with two glands respectively between the both ends of dabber and the roller, has all installed TC skeleton oil blanket and for the axle ladder circle between dabber and the two glands, installs the spacer bush corresponding with the dabber between gland and the biserial tapered roller bearing, and the little round nut corresponding with the gland has all been installed at the both ends of dabber.

Furthermore, a round nut stop washer is arranged between the small round nut and the double-row tapered roller bearing.

Further, a first O-shaped ring is arranged between the gland and the inner wall of the roller.

Further, a second O-shaped ring is arranged between the double-row tapered roller bearing and the gland.

Further, a sealing structure is formed among the mandrel, the two pressing covers, the TC framework oil seal and the stepped ring for the shaft.

Furthermore, an inner hexagon bolt is arranged between the gland and the roller.

Furthermore, lubricating grease is arranged between the double-row tapered roller bearing and the roller and between the double-row tapered roller bearing and the mandrel.

The utility model has the beneficial effects that: the utility model relates to a tension compression roller, which comprises a mandrel; a gland; TC framework oil seal; step ring for shaft; double row tapered roller bearing.

1. The TC framework oil seal and the stepped ring for the shaft are arranged between the mandrel and the two pressing covers, so that the joint of the mandrel and the pressing covers can be well sealed, and water is prevented from entering the tension press roller from the joint of the mandrel and the pressing covers to affect the tension press roller.

2. By installing the double-row tapered roller bearings and adjusting the positions of the double-row tapered roller bearings, the bearing capacity of the double-row tapered roller bearings in the axial direction and the radial direction can be improved by installing the double-row tapered roller bearings at the two ends of the mandrel, so that the service life of the tension press roller can be prolonged to 12-18 months compared with the service life of the original tension press roller for 2-4 months.

Detailed Description

The utility model is further described in connection with the following detailed description, in order to make the technical means, the creation characteristics, the achievement of the purpose and the effect of the utility model easy to understand.

Referring to fig. 1 and 2, the present utility model provides a technical solution: the utility model provides a tension compression roller, includes dabber 1 and roller 10, dabber 1 is located roller 10, and gland 12 has all been installed at the both ends of roller 10, installs the biserial tapered roller bearing 8 that respectively correspond with two glands 12 between dabber 1's both ends and the roller 10, has all installed TC skeleton oil blanket 2 and for the axle ladder circle 3 between dabber 1 and two glands 12, installs the spacer bush 5 corresponding with dabber 1 between gland 12 and the biserial tapered roller bearing 8, and little round nut 6 corresponding with gland 12 has all been installed at dabber 1's both ends.

In the embodiment, a round nut stop washer 7 is arranged between a small round nut 6 and a double-row tapered roller bearing 8, a first O-shaped ring 4 is arranged between a gland 12 and the inner wall of a roller 10, a second O-shaped ring 11 is arranged between the double-row tapered roller bearing 8 and the gland 12, a sealing structure is formed among a mandrel 1, two glands 12, a TC framework oil seal 2 and a shaft stepped ring 3, an inner hexagon bolt 9 is arranged between the gland 12 and the roller 10, and lubricating grease is arranged between the double-row tapered roller bearing 8 and the roller 10 as well as between the mandrel 1.
