The utility model provides an upper supporting roller further sets up to: the main shaft vertically penetrates through the inside of the supporting roller.

The utility model provides an upper supporting roller further sets up to: the shaft sleeve is made of polyurethane rubber.

The utility model provides an upper supporting roller further sets up to: the oil seals are symmetrical with each other about a longitudinal central axis of the main shaft.

The utility model provides an upper supporting roller further sets up to: the lower surface of the bearing is tightly attached to the upper surface of the bearing base.

The utility model provides an upper supporting roller further sets up to: the screw and the washer form a disassembly structure.

Compared with the prior art, the utility model discloses following beneficial effect has:

(1) this go up the supporting roll, be the polyurethane rubber coating through the axle sleeve, wrap up the axle sleeve in the outside of main shaft, the axle sleeve is polyurethane rubber coated roller, and the supporting roll that prevents that can be fine is too big at operation in-process noise, and the axle sleeve can reduce appropriate amount of noise, can not make the bucket wheel body wearing and tearing big simultaneously to influence the use of whole supporting roll.

(2) The upper supporting roller is of a disassembly structure formed by the screw and the gasket, the gasket is sleeved outside the screw, and the friction force of the screw can be increased, so that the fixing position of the screw is firmer.

[ description of the drawings ]

Fig. 1 is a schematic view of the overall structure of the present invention;

fig. 2 is a schematic side view of the present invention.

In the figure: 1. the device comprises a main shaft, 2, a supporting roller, 3, a shaft sleeve, 4, an oil seal, 5, a bearing, 6, a bearing base, 7, a bolt, 8, a taper pin, 9, a screw, 10, a red steel plate, 11 and a gasket.

[ detailed description ] embodiments

An upper support roller according to the present invention will be described in further detail with reference to the following embodiments.

As shown in fig. 1-2, the utility model provides a technical solution: an upper supporting roller comprises a main shaft 1, a supporting roller wheel 2, a shaft sleeve 3, an oil seal 4, a bearing 5, a bearing base 6, a bolt 7, a taper pin 8, a screw 9, a red steel plate 10 and a gasket 11, wherein the supporting roller wheel 2 is sleeved outside the main shaft 1, the shaft sleeve 3 is arranged on the left side of the supporting roller wheel 2, the oil seal 4 is arranged at the upper end and the lower end of the left side of the shaft sleeve 3, the bearing 5 is arranged on the left side of the oil seal 4, the bearing base 6 is arranged at the lower end of the bearing 5, the bolt 7 is arranged inside the upper end of the bearing 5, the taper pin 8 is arranged at the front end and the rear end of the bearing 5, the screw 9 is arranged on the inner side of;

the main shaft 1 vertically penetrates through the inside of the supporting roller 2, and the supporting roller 2 can be sleeved outside the main shaft 1;
