SUMMERY OF THE UTILITY MODEL

The utility model aims at providing a rolling device installs the bearing between gyro wheel and transmission shaft, sets up the retaining ring on the bearing, adjusts conveying speed through the speed of bearing operation, need not the shut down and changes the sprocket, can furthest's assurance production the continuity, the retaining ring has reduced the metal friction greatly reduced noise of bearing and gyro wheel simultaneously.

The utility model provides a rolling device, including transmission shaft, bearing, gyro wheel and sleeve, the bearing passes through the mounting screw on the transmission shaft, the gyro wheel passes through the sleeve to be fixed the gyro wheel on the transmission shaft, be provided with spacer ring and spacer ring retaining ring between bearing and the transmission shaft, be equipped with gyro wheel retaining ring and piston ring between gyro wheel and the transmission shaft, play sealed effect between gyro wheel and the transmission shaft through gyro wheel retaining ring, piston ring and sleeve.

The further improvement lies in that: and a bearing retainer ring is arranged between the roller and the bearing.

The further improvement lies in that: the transmission shaft is provided with a straight-through type pressure injection oil cup, and an oil cup retainer ring is arranged between the straight-through type pressure injection oil cup and the transmission shaft.

The further improvement lies in that: and a pressing plate is arranged outside the oil cup retainer ring and forms a protective layer outside the straight-through type pressure injection oil cup.

Chain conveyor rolling device generally adopts drive sprocket, if there is different conveying speed's needs in the material transportation process, can only shut down, the artifical drive sprocket that changes, the adjustment tooth ratio, just can change the functioning speed of chain piece, neither safety influences production again, this application installs the bearing between gyro wheel and transmission shaft, set up the bearing retaining ring on the bearing, adjust conveying speed through the speed of bearing operation, it changes the sprocket to need not to shut down, the continuity of furthest's assurance production, the metal friction greatly reduced the noise that the bearing retaining ring has reduced bearing and gyro wheel simultaneously. The roller is externally provided with a roller retainer ring, an expansion ring and a sleeve to form sealing, the structure is compact, sliding friction is replaced by rolling friction, the running resistance is low, no dust is leaked into the roller in the material conveying process, the abrasion is reduced, and the service life of the roller is prolonged. The direct-through type pressure filling oil cup on a general transmission shaft directly fills lubricating grease into the oil cup, the lubricating grease is screwed by the oil cup cover, and the oil cup is inevitably damaged or loosened due to vibration when the lubricating grease is lubricated.

The utility model discloses beneficial effect: the conveying speed is adjusted through the speed of the bearing operation, the chain wheel does not need to be replaced after the machine is stopped, the production continuity can be ensured to the maximum extent, and meanwhile, the metal friction between the bearing and the roller is reduced by the retainer ring, so that the noise is greatly reduced; the roller is externally provided with the check ring, the piston ring and the sleeve to form sealing, the structure is compact, sliding friction is replaced by rolling friction, the running resistance is low, no dust is leaked into the roller in the material conveying process, the abrasion is reduced, and the service life of the roller is prolonged.
