Description
Technical field
The utility model is related to a kind of bearings, more particularly, to a kind of double-row angular contact bal bearing with greasing hole.
Background technology
Double-row angular contact bal bearing can bear radial and axial joint load based on larger radial load and torque is negative
Lotus limits the both sides axial displacement of axis.It is mainly used for limiting in axis and the component of shell bi-directional axial displacement.
Double row angular contact is one kind of bearing type, the design of double-row angular contact bal bearing substantially with single-row angular contact ball
Bearing is identical, but only takes up smaller axial space.Double-row angular contact bal bearing can bear radial load and act on two
The axial load in direction, it can limit axis or shell bi-directional axial displacement.Bearing configuration with a higher rigidity can be provided, and can be held
By tilting moment.
Double-row angular contact bal bearing in prior art is in operation process, when internal lubrication fat is lost in because of high temperature failure,
It needs to dismantle the filling that double-row angular contact bal bearing carries out grease, to keep the good greasy property of bearing, and can also reduce
Friction between bearing and axis, but there is the technical problem of dismounting trouble and fat inconvenience of refueling.
Utility model content
The utility model devises a kind of double-row angular contact bal bearing with greasing hole, and the technical issues of solving is existing
Double-row angular contact bal bearing in technology is in operation process, when internal lubrication fat is lost in because of high temperature failure, needs to dismantle biserial
Angular contact ball bearing carries out the filling of grease, but there is the technical problem of dismounting trouble and fat inconvenience of refueling.
In order to solve above-mentioned technical problem, the utility model uses following scheme:
A kind of double-row angular contact bal bearing with greasing hole, including bearing outer ring (1) and bearing inner race (2), bearing outer ring
(1) and common the top of bearing inner race (2) with common bottom to be respectively equipped with a dust-proof sealing structure (3), bearing outer ring
(1) raceway between bearing inner race (2) is vertically equipped with upper layer steel ball (5) and lower layer's steel ball (6), it is characterised in that:In bearing
The greasing hole that is radially equipped with of inner ring (2) leads to (7), and exterior space, the greasing through-hole are led in described greasing through-hole (7) one end
(7) other end leads to the junction of upper layer steel ball (5) and lower layer's steel ball (6), and lubricating grease enters raceway by greasing through-hole (7).
Further, dust-proof sealing structure (3) includes dustproof cover and sealing ring, dustproof cover in bearing outer ring (1) and bearing
The junction of circle (2) is sealed by a seal ring.
Further, upper layer steel ball (5) and lower layer's steel ball (6) are designed with a mounting hole, upper layer steel ball (5) and lower layer's steel ball
(6) mounting hole is entered by a retainer (4) respectively, and retainer (4) limits upper layer steel ball (5) and lower layer's steel ball (6) rotation
Direction.
The double-row angular contact bal bearing with greasing hole has below compared with traditional double-row angular contact bal bearing beneficial to effect
Fruit:
(1) double-row angular contact bal bearing of the utility model with greasing hole so that bearing exempts to dismount, and realizes repeatedly supplement profit
The occasion of consistent lubricant, it is easy to utilize.
(2) the utility model is equipped with greasing hole on bearing inner race can greatly reduce friction, improve lubricating condition, from
And extend the service life of bearing.

Specific implementation mode
With reference to Fig. 1, the utility model is described further:
As shown in Figure 1, a kind of double-row angular contact bal bearing with greasing hole, including bearing outer ring 1 and bearing inner race 2, axis
Common the top of bearing outer-ring 1 and bearing inner race 2 with common bottom to be respectively equipped with a dust-proof sealing structure 3, bearing outer ring 1
Raceway between bearing inner race 2 is vertically equipped with upper layer steel ball 5 and lower layer's steel ball 6, and greasing is radially equipped in bearing inner race 2
Hole logical 7, lead to 7 one end of greasing through-hole exterior space, and 7 other end of greasing through-hole leads to the connection of upper layer steel ball 5 and lower layer's steel ball 6
Place, lubricating grease enter raceway by greasing through-hole 7.
Dust-proof sealing structure 3 includes dustproof cover and sealing ring, the junction of dustproof cover and bearing outer ring 1 and bearing inner race 2
It is sealed by a seal ring.Upper layer steel ball 5 and lower layer's steel ball 6 are designed with a mounting hole, upper layer steel ball 5 and lower layer's steel ball 6
Mounting hole is entered by a retainer 4 respectively, and retainer 4 limits upper layer steel ball 5 and 6 direction of rotation of lower layer's steel ball.
Compared with the prior art, the bearing with greasing hole may be implemented to exempt to dismount, and repeatedly refuel fat.When bearing was operating
Cheng Zhong when internal lubrication fat is lost in because of high temperature failure, does not have to dismounting bearing, can directly be supplemented to Bearing inner by greasing hole
Lubricating grease keeps the good greasy property of bearing, and can also reduce the friction between bearing and axis.
Illustrative description has been carried out to the utility model above in conjunction with attached drawing, it is clear that the realization of the utility model not by
The limitation of aforesaid way, if the various improvement of the methodology and technical solution progress of the utility model are used, or without
It improves and the design of the utility model and technical solution is directly applied into other occasions, in the scope of protection of the utility model
It is interior.
