A kind of urgently dust-proof, etch-proof bearing screw rod of exploitation.
Invention content
In order to overcome shortcoming and defect existing in the prior art, the purpose of this utility model is to provide kind of a dustproof anticorrosives
The bearing built-in screw rod of erosion, the matched bearing of the screw rod can dustproof anticorrosive erosion, and it is simple in structure, it is easy for installation.
The purpose of this utility model is achieved through the following technical solutions：A kind of bearing built-in screw rod of dustproof anticorrosive erosion,
Including screw rod, the bearing assembly that is sheathed on screw rod, it is connected to seal assembly of the bearing assembly for sealed bearing assembly.
Further, the bearing assembly include the axle sleeve for being sheathed on screw rod, the bearing that is installed in axle sleeve, the bearing
It is connect with screw coaxial.
Further, the axle sleeve includes the second part for being sheathed on the first part of screw rod and being connect with first part,
The diameter of the second part is more than the diameter of first part, and bearing is installed in second part and coaxially connects with first part
It connects.
Further, the seal assembly include the thimble being sheathed in bearing, the extension being connect with thimble and with prolong
The flange of extending portion connection, the thimble are respectively positioned on extension in axle sleeve, and the flange abuts axle sleeve.
Further, the seal assembly further includes the nut of connection and extension, is arranged the pipe sleeve and use with extension
Pipe sleeve is abutted in one end of the oil sealing of sealing, the oil sealing, the other end of oil sealing abuts bearing.
Further, the pipe sleeve is copper pipe set.
The beneficial effects of the utility model are：The utility model is by the way that bearing holder (housing, cover) to be set on screw rod, and than traditional axis
Seal assembly has been held more than screw rod, and can play prevents dust from entering in bearing in this way, damages bearing；It can avoid bearing and sky simultaneously
The contact of gas and water plays corrosion-resisting function, effectively extends the service life of bearing screw rod.

Specific implementation mode
For the ease of the understanding of those skilled in the art, the utility model is made into one with reference to embodiment and attached drawing 1
The explanation of step, the content that embodiment refers to not are the restriction to the utility model.
Please refer to attached drawing 1, a kind of bearing built-in screw rod of dustproof anticorrosive erosion, including screw rod 1, the axis for being sheathed on screw rod 1
Bearing assembly 2 is connected to seal assembly 3 of the bearing assembly 2 for sealed bearing assembly 2.
The utility model is by the way that bearing 22 to be sheathed on screw rod 1, and the seal assembly 3 more than traditional bearing screw rod, this
Sample, which can play, prevents dust from entering in bearing 22, to damage bearing 22；It can avoid connecing for bearing 22 and air and water simultaneously
It touches, plays corrosion-resisting function, effectively extend the service life of 22 screw rod 1 of bearing.
Further, the bearing assembly 2 includes being sheathed on the axle sleeve 21 of screw rod 1, the bearing 22 being installed in axle sleeve 21,
The bearing 22 and screw rod 1 are coaxially connected.
The utility model reduces the chance that bearing 22 is contacted with the external world, plays by the way that bearing 22 to be installed in axle sleeve 21
Dust-proof effect.
Further, the axle sleeve 21 includes being sheathed on the first part 211 of screw rod 1 and being connect with first part 211
Second part 212, the diameter of the second part 212 are more than the diameter of first part 211, and bearing 22 is installed in second part
It is in 212 and coaxially connected with first part 211.
For the use of the new type by two parts for being set as being connected with each other by axle sleeve 21, first part 211 is socketed on screw rod 1
It is interior, bearing 22 and first part 211 is coaxially connected and in the second part 212, it is effective reduce bearing 22 with it is extraneous
The probability of connection plays dust-proof effect.
Further, the seal assembly 3 includes the thimble 31 being sheathed in bearing 22, the extension being connect with thimble 31
32 and the flange 33 that is connect with extension 32, the thimble 31 be respectively positioned in axle sleeve 21 with extension 32, the flange 33 abuts
Axle sleeve 21.
The utility model is by setting seal assembly 3 to the thimble being sheathed in bearing 22 31, connecting with thimble 31
