Description
Technical field
It the utility model is related to field of bearings, more particularly to the dust-proof rolling bearing that a kind of Spring Card is spacing.
Background technology
Bearing is a kind of important parts in contemporary plant equipment, and its major function is the mechanical rotary body of support, is dropped
Coefficient of friction in low mechanical rotary body motion process, and ensure its rotating accuracy.
By the difference of motor element frictional property, bearing can be divided into rolling bearing and the major class of sliding bearing two, wherein rolling
Bearing is normalized, seriation, but its radial dimension, vibration and noise are larger compared with sliding bearing, and price is also higher.
Rolling bearing is typically made up of outer ring, inner ring, rolling element and the part of retainer four, and the effect of radial support is good, but
It is to be difficult to undertake larger axial force, and dirt exclusion capabilities are limited.
Utility model content
The purpose of this utility model is to provide a kind of Spring Card spacing dust-proof rolling bearing, lifts dust-proof effect and axle
To structural strength.
To use following technical scheme up to this purpose, the utility model：
A kind of spacing dust-proof rolling bearing of Spring Card, including：Bearing outer ring and bearing inner race, the bearing inner race are concentric
It is arranged among bearing outer ring, circle cylinder swivel is provided between the bearing outer ring inwall and bearing inner race and carries out rolling company
Connect, the sealing ring positioned at cylinder swivel both sides, the sealing ring medial surface and cylinder swivel are provided with the bearing outer ring
Ball is respectively arranged between end and carries out rolling connection, the bullet being respectively arranged with the bearing outer ring on the outside of sealing ring
Spring card.
Wherein, the end set of the cylinder swivel has the first arc groove corresponding with ball.
Wherein, the sealing ring medial surface is arranged at intervals with the second arc groove corresponding with ball.
Wherein, it is respectively arranged with the bearing outer ring inwall and corresponding with Spring Card neck is installed.
Wherein, the bearing outer ring side is provided with the oil filler point for pointing to cylinder swivel.
Wherein, evagination is provided with the first spacing collar positioned at cylinder swivel both sides on the bearing outer ring inwall.
Wherein, evagination is provided with the second spacing collar positioned at cylinder swivel both sides on the bearing inner race outer wall.
The beneficial effects of the utility model：The spacing dust-proof rolling bearing of a kind of Spring Card, using Spring Card to sealing ring
Spacing, the structural stability and dust seal effect of lift-off seal ring are carried out, spacing, utilization is being carried out to ball using sealing ring
Ball is rotated to resist the friction of cylinder swivel, and the axial direction of lifting cylinder swivel supports, and structural stability is good.
