Abstract
It the utility model proposes the sealing structure of protection bearing in bearing block, can play a protective role, and realize zero abrasion and radiating effect, can be used for a long time.The structure includes sealing ring, labyrinth ring and O-ring；Bearing block is equipped with bearing gland built with several bearings, one end of bearing block, and sealing ring is installed in the other end of bearing block, bearing gland and is set with labyrinth ring；One screw mandrel penetrates bearing block and sequentially passes through sealing ring, several bearings and labyrinth ring；The madial wall of sealing ring is arranged with an annular groove along its circumference, and O-ring is embedded in the annular groove, and sealing ring is interference fitted by O-ring and screw mandrel.The utility model along its circumference in sealing ring madial wall by being arranged with an annular groove, O-ring is embedded in the annular groove, and it is interference fitted with screw mandrel formation, screw mandrel is in actual use because the waste oil that lubrication is produced can be in screw mandrel surface following current to sealing ring, because the sealing function of O-ring is so waste oil will not enter inside bearing block.
Description
Technical field
The utility model belongs to machine tool technology field, more particularly to the sealing structure of protection bearing in bearing block.
Background technology
The screw rod transmission structure of current machine industry, protects the mode of bearing, all with oil sealing, and on the one hand bearing block is processed
It is required that high, the long-term use of another aspect oil sealing is easy to wear, causes seal failure, does not reach protection bearing effect.
Utility model content
The utility model proposes the sealing structure of protection bearing in bearing block, it can play a protective role, and realize zero
Abrasion and radiating effect, can be used for a long time.
Technical solutions of the utility model are as follows：
Protect the sealing structure of bearing in bearing block, including sealing ring, labyrinth ring and O-ring；Bearing block is built with some
Individual bearing, one end of bearing block is equipped with bearing gland, and the sealing ring is installed in the other end of bearing block, the bearing gland
It is set with labyrinth ring；One screw mandrel penetrates the bearing block and sequentially passes through sealing ring, several bearings and labyrinth ring；The sealing
The madial wall of ring is arranged with an annular groove along its circumference, and the O-ring is embedded in the annular groove, and the sealing ring is by O-ring and silk
Bar is interference fitted.
Further, the bearing block is installed and a heavy oil groove is circumferentially arranged with one end end face of sealing ring, described close
Seal ring is placed on heavy oil groove provided with a barb-like extension, and one and unloading that the heavy oil groove is connected are offered on the bearing block
Oilhole.
Further, gap coordinates between the sealing ring and bearing block.
Further, in addition to spacer ring, the spacer ring be arranged at several bearings wherein adjacent two bearings it
Between, the spacer ring includes outer spacer ring and interior spacer ring.
By above description, compared with prior art, the utility model has the following advantages that the utility model：
1st, O-ring is embedded in the annular groove by the utility model by being arranged with an annular groove along its circumference in sealing ring madial wall
It is interior, and be interference fitted with screw mandrel formation, screw mandrel is in actual use because the waste oil that lubrication is produced can be along screw mandrel surface
On following current to sealing ring, because O-ring sealing function thus waste oil will not enter bearing block inside, prevent lubricating oil from entering axle
Hold internal ice and be drained to outside.
2nd, the utility model is concavely provided with heavy oil groove in the end face of bearing block, when waste oil cannot be introduced into inside bearing block,
It can overflow into heavy oil groove, ice is discharged from oilhole is unloaded.
3rd, O-ring of the present utility model is interference fitted in screw mandrel, and when screw mandrel is rotated, sealing ring is by O types circle and screw mandrel
Together rotate, while coordinate in bearing block gap, realize heat that the bearing in zero abrasion, bearing block operationally produces via
Gap discharge of gap and labyrinth ring of the sealing ring between bearing block between bearing gland, reduces thermal deformation.
