Abstract
The utility model belongs to technical field of bearings, the Biserial cylindrical roller bearing of specifically a kind of pulley blocks collection sealing and dustproof and one.The bearing includes outer ring, inner ring, rolling element, inner ring fuel feed hole, locating snap ring, and the bearing further includes dustproof cover, card slot and Spring Card；Card slot is located in outer rollaway nest, and Spring Card is embedded in card slot, and outer diameter and the outer rollaway nest of dustproof cover are interference fitted, and there are gaps for the internal diameter of dustproof cover and the rib of inner ring.The utility model bearing integrates sealing and dustproof, not only strengthens the overall structure of bearing, and can prevent the bearing sequence of sanqu songs within a particular musical mode, need not fix two bearing inner races using retainer again, increase the efficiency of assembling of bearing, reduce processing cost.
Description
Technical field
The utility model belongs to technical field of bearings, and specifically a kind of pulley blocks are justified with collection sealing and dustproof and the biserial of one
Column rod bearing.
Background technology
Pulley blocks are used in fields such as handling machinery, mining machinery, building machinery, shop traveller, deep-sea engineerings,
With the development of modern science and technology, pulley blocks also experienced development and change at full speed, and play rotation supporting role to pulley blocks
Bearing play crucial effect wherein.Pulley blocks require light dead-weight, high-mechanic, high rotating speed, are convenient for lubricating maintenance, therewith
Mating bearing will also reach these requirements.
In some engineerings, line speed is high, and frequent starting, thus difficulty meets modern production to traditional pulley blocks
Efficiently, the requirement of high quality, high reliability, it is increasingly arduous that research and development Novel pulley group obtains task, at the same time, research and development and pulley blocks
Mating bearing is also extremely urgent.
Invention content
The purpose of this utility model is to provide a kind of Biserial cylindrical roller bearing of pulley blocks collection sealing and dustproof and one.
For achieving the above object, the utility model uses following technical scheme：
A kind of pulley blocks Biserial cylindrical roller bearing for integrating sealing and dustproof, including outer ring, inner ring, rolling element,
Inner ring fuel feed hole, locating snap ring, which is characterized in that the bearing further includes dustproof cover, Spring Card；Spring Card is embedded in outer rollaway nest
In card slot, outer diameter and the outer rollaway nest of dustproof cover are interference fitted, and there are gaps for the internal diameter of dustproof cover and the rib of inner ring.
Compared with prior art, the beneficial effects of the utility model are：Bearing of the present invention integrates sealing and dustproof, not only
The overall structure of bearing is strengthened, and the bearing sequence of sanqu songs within a particular musical mode can be prevented, need not two bearing inner races be fixed using retainer again, is increased
The efficiency of assembling of bearing, reduces processing cost.

Specific implementation mode
The utility model is described further below in conjunction with specific implementation mode.
A kind of pulley blocks Biserial cylindrical roller bearing for integrating sealing and dustproof, including outer ring 01, inner ring 02, rolling
Body 03, inner ring fuel feed hole 07, locating snap ring 04, which is characterized in that the bearing further includes dustproof cover 05, Spring Card 06；Slot
In in outer rollaway nest, Spring Card 06 is embedded in the card slot in outer rollaway nest, and outer diameter and the outer rollaway nest of dustproof cover 05 are interference fitted, dustproof cover
There are gaps for the rib of 05 internal diameter and inner ring.
Dustproof cover outer diameter and outer rollaway nest are interference fitted by the utility model bearing, and the rib of dustproof cover internal diameter and inner ring has one
Fixed gap A（See attached drawing 2）, ensure that lubricant cannot be leaked from Bearing inner when bearing operation, and can be below certain oil pressure
Just pulley blocks internal bearings lubricant is replaced, discarded lubricant is passed through dustproof cover and inner ring rib by new lubricant
Gap A ejection, play the role of sealing and dustproof；Spring Card is embedded in the card slot of outer rollaway nest, not only strengthens the entirety of bearing
Structure, and the bearing sequence of sanqu songs within a particular musical mode can be prevented, need not two bearing inner races be fixed using retainer again, increase the assembly effect of bearing
Rate reduces processing cost.
