Fixed parts.Bearing is a kind of very important parts in contemporary plant equipment.Its major function is support machinery rotation
Swivel, to reduce mechanical load coefficient of friction of the equipment in transmission process.By the difference of motor element frictional property, bearing
Rolling bearing and the class of sliding bearing two can be divided into.Bearing is the important foundation parts of all kinds of mechanized equipments, its precision, property
Energy, life and reliability play conclusive effect to the precision, performance, life and reliability of main frame.In engineering goods, axle
Hold and belong to high-precision product, not only need the comprehensive support that the subjects such as mathematics, physics are theoretical, and need material science,
Heat treatment technics, Precision Machining and e measurement technology, Numeric Control Technology and effective numerical method and powerful computer technology
Serviced for it Deng subjects, therefore bearing is a product for representing national science and technology strength again.
Bearing block is for connection to the part with spring bearing, and existing bearing block does not possess dust reduction capability, and dust holds very much
Easily paste on bearing, influence the rotation of bearing, dismantled during bearing cleaning very inconvenient.
The content of the invention
It is an object of the invention to provide a kind of dustproof bearing seat, to solve the problems mentioned in the above background technology.
To achieve the above object, the present invention provides following technical scheme：A kind of dustproof bearing seat, including main body, the master
Body is made up of bearing base and bearing cap, and the both sides of the bearing cap are bolted to connection on the bearing base, institute
State and cylinder roller bearing is installed between bearing base and bearing cap, the outer ring of the cylinder roller bearing and the bearing base
It is fixedly connected with bearing cap, the inner ring of the cylinder roller bearing is fixedly installed synchronous axle sleeve, the bearing base and bearing
The position of synchronizing shaft set contact described in Gai Yu is provided with annular projection, and the outer surface of the synchronous axle sleeve is in correspondence annular
Raised position offers the groove adaptable with annular projection, and the annular projection is embedded in the recessed of the synchronous axle sleeve
In groove, dust ring is provided with the groove.
It is preferred that, the synchronous axle sleeve is internally provided with the axis hole for installing rotating shaft, and the side wall of the synchronous axle sleeve is opened
Provided with spacing screw.
It is preferred that, oil filler point is provided with the top of the bearing cap, the oil filler point is connected with cylinder roller bearing.
It is preferred that, the annular projection is located at the both sides of the cylinder roller bearing.
It is preferred that, the dust ring is O-ring.
Compared with prior art, the beneficial effects of the invention are as follows：
1st, the present invention is synchronous by being provided with annular projection in the position contacted with synchronizing shaft set in bearing base and bearing cap
The outer surface of axle sleeve offers the groove adaptable with annular projection in the raised position of correspondence annular, and annular is raised
In the groove for being embedded in synchronous axle sleeve, so as to be set by the raised turning of annular, effectively it can prevent dust from entering
Enter in cylinder roller bearing.
2nd, the present invention, being capable of further protection and sealing circle by setting dust ring between annular projection and groove
Post roller bearing, has the advantages that simple in construction, easy to use, using effect is good.
